<p>College life, often depicted as exhilarating and liberating, is also synonymous with stress due to the amalgamation of academic pressures, work, and personal responsibilities. Recognizing the myriad of pressures students face, universities have initiated innovative stress relief programs. One such program named “Pet Your Stress Away” encourages students to pet <a href="https://www.earth.com/news/therapy-dogs-boost-cognitive-skills-in-college-students/" target="_blank" rel="noreferrer noopener">dogs</a> and cats. </p>



<p>The essence of these programs is allowing students to interact with furry friends, aiming to alleviate stress and improve overall mood. Scientists at <a href="https://wsu.edu/" target="_blank" rel="noreferrer noopener">Washington State University</a> (WSU) have substantiated the effectiveness of these programs, revealing their capability to yield significant stress-relieving physiological benefits beyond just elevating moods.</p>



<h2 class="wp-block-heading" id="h-reaping-benefits-in-just-ten-minutes">Reaping benefits in just ten minutes</h2>



<p>Patricia Pendry, an Associate Professor in WSU’s Department of Human Development, underscores the impact of animal interaction, stating, “Just 10 minutes can have a significant impact”. </p>



<p>The study, conducted by Pendry along with WSU graduate student Jaymie Vandagriff and published in <a href="https://journals.sagepub.com/doi/10.1177/2332858419852592" target="_blank" rel="noreferrer noopener">AERA Open</a>, demonstrated that students experiencing interaction with cats and dogs showed a marked reduction in cortisol, a major stress hormone. </p>



<p>These findings are pivotal as they represent the first instance where reductions in cortisol levels in students were observed during a real-life intervention outside the laboratory setting.</p>



<h2 class="wp-block-heading" id="h-how-the-study-was-conducted">How the study was conducted</h2>



<p>The meticulously designed study included 249 college students who were randomly segregated into four distinct groups. The students in the first group were given the opportunity to interact directly with cats and <a href="https://www.earth.com/news/your-dog-feel-stress/" target="_blank" rel="noreferrer noopener">dogs</a>, allowing them to pet and play with the animals for ten minutes. </p>



<p>To gauge the variable impacts of differing animal exposures, the second group observed others interacting with the animals while awaiting their turn. The third group viewed a slideshow featuring the animals, and the fourth was waitlisted, anticipating interaction but initially without any engagement or stimuli.</p>



<h2 class="wp-block-heading" id="h-significant-cortisol-reduction-from-petting-dogs">Significant cortisol reduction from petting dogs</h2>



<p>The methodological approach included collecting several salivary cortisol samples from each participant from the time they woke up. The subsequent data analysis revealed that students who engaged directly with the animals exhibited significantly lower cortisol levels in their saliva post-interaction. These compelling results remained consistent, even accounting for the varying initial cortisol levels amongst students.</p>



<p>Benefits beyond surface-level</p>



<p>Universities' incorporation of “Pet Your Stress Away” programs is rooted in the acknowledgement of the multi-faceted pressures inundating students. These programs don’t merely serve as a transient mood enhancer. They penetrate deeper, offering tangible physiological benefits by significantly reducing stress levels.</p>



<p> The study validates the potency of these programs, highlighting their ability to create a holistic, positive impact within a mere ten-minute interaction window.</p>



<p>In summary, the innovative stress reduction programs instituted by many universities manifest a proactive approach to address the escalating stress levels amongst students, combining academic vigor with emotional well-being. The conclusive evidence provided by the study conducted at Washington State University accentuates the vital role such programs can play in fostering a balanced and conducive learning or working environment. </p>



<p>By allowing a short respite through animal interaction, universities are not just enhancing student mood but are also contributing to their overall well-being by inducing physiological changes that combat stress.</p>

<p>In a recent study led by Professor Adrian David Cheok at the <a href="https://www.u-tokyo.ac.jp/en/" target="_blank" rel="noreferrer noopener">University of Tokyo</a>, researchers have successfully deciphered the emotional states of chickens through their <a href="https://www.earth.com/news/zebra-finches-use-both-calls-and-vision-to-coordinate-flight/">vocalizations</a>. This unique endeavor seeks to bridge the interspecies communication gap.</p>



<h2 class="wp-block-heading" id="h-chicken-vocalizations">Chicken vocalizations</h2>



<p>The research, which is still awaiting peer review, has reported a groundbreaking achievement. The team determined the six emotional states of chickens - hunger, fear, anger, contentment, excitement, and distress - with 80% accuracy solely based on vocalizations.&nbsp;</p>



<p>The preliminary findings have been documented in a paper submitted to <em>Nature Scientific Reports</em> and initially published in <a href="https://www.researchsquare.com/article/rs-3034567/v1" target="_blank" rel="noreferrer noopener">Research Square</a>.</p>



<p>Cheok, otherwise recognized for his sex robot research, humorously commented on this novel venture: “It’s a cluckin’ great leap for science! And this is just the beginning."</p>



<p>"We hope to be able to adapt these AI and ML techniques to other animals and lay the groundwork for incredible intelligence in the various animal-related industries. If we know what animals are feeling we can design a much better world for them.”</p>



<h2 class="wp-block-heading" id="h-deep-emotional-analysis-learning-deal">Deep Emotional Analysis Learning (DEAL)</h2>



<p>“Our methodology employs a cutting-edge AI technique we call Deep Emotional Analysis Learning (DEAL), a highly mathematical and innovative approach that allows for the nuanced understanding of emotional states through auditory data,” explained Cheok.&nbsp;</p>



<p>The innovative AI technique holds the promise of designing a more humane environment for animals by better comprehending their feelings.</p>



<h2 class="wp-block-heading" id="h-collaborative-expertise-nbsp">Collaborative expertise&nbsp;</h2>



<p>"We conducted our study with a sample of 80 chickens, meticulously recording and analyzing their vocalizations under various conditions," wrote the study authors.&nbsp;</p>



<p>"To ensure the accuracy of our system's interpretations, we collaborated with a team of eight animal psychologists and veterinary surgeons, who provided expert insights into the emotional states of the chickens."</p>



<h2 class="wp-block-heading" id="h-accurate-results">Accurate results</h2>



<p>The researchers meticulously analyzed approximately 200 hours of chicken sounds. The AI system was trained on half of these recordings, where each sound was labeled with a corresponding emotional state.&nbsp;</p>



<p>When tested on the remaining 100 hours of chicken vocalizations, the system impressively pinpointed the chickens' emotional states most of the time.</p>



<h2 class="wp-block-heading" id="h-animal-welfare">Animal welfare</h2>



<p>“This research not only opens up new avenues for understanding and improving animal welfare but also sets a precedent for further studies in AI-driven interspecies communication,” said the study authors.</p>



<p>They noted that chickens are “highly social animals” and plan to create a free app so that farmers can use the technology to communicate with their chickens.</p>



<p>According to the researchers, this study not only enhances our understanding of animal welfare but also sets the foundation for further exploration in AI-facilitated interspecies communication.&nbsp;</p>



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



<p>Farming Online recognizes the immense potential of this research, saying that it could redefine animal welfare, advance veterinary medicine, improve poultry farming conditions, and assist animal behavior research, among other applications.</p>



<p>"The novelty of our approach lies in its application of sophisticated AI techniques to a largely unexplored area of study," concluded the researchers.</p>



<p>"By bridging the gap between human and animal communication, we believe our research will pave the way for more empathetic and effective interactions with the animal kingdom."</p>

AI can now interpret the emotional states of chickens through their noises

In a recent study led by Professor Adrian David Cheok...

<p>A recent study from <a href="https://www.elte.hu/en/" target="_blank" rel="noreferrer noopener">Eötvös Loránd University</a> has explored the question of why flat-faced dogs are so popular despite their major health risks.&nbsp;</p>



<p>The results of the study suggest that flat-faced dogs such as pugs and <a href="https://www.earth.com/news/english-bulldogs-are-suffering-from-poor-breeding-practices/">bulldogs</a> have infant-like traits and behaviors that humans find irresistible.</p>



<p>"Infant-like traits may be present not only in appearance but also in behavior in brachycephalic breeds, eliciting caring behavior in owners," wrote the study authors.</p>



<h2 class="wp-block-heading" id="h-health-issues">Health issues</h2>



<p>Pugs and French bulldogs, with their wrinkled faces and flat noses, have charmed their way into the hearts of many dog lovers</p>



<p>However, these brachycephalic breeds are also prone to severe health issues, raising questions about the seemingly paradoxical rise in their popularity.&nbsp;</p>



<h2 class="wp-block-heading" id="h-why-are-brachycephalic-dogs-so-popular">Why are brachycephalic dogs so popular?</h2>



<p>The term "brachycephalic" refers to breeds of dogs that have flattened faces and shortened muzzles, a result of selective breeding rather than natural evolution.&nbsp;</p>



<p>Despite the known health risks, such as breathing and skin problems, these breeds have witnessed an unprecedented rise in ownership in recent years.&nbsp;</p>



<p>The Kennel Club reported a 2,747-percent increase in registered French Bulldogs since 2004 in the UK alone.</p>



<h2 class="wp-block-heading" id="h-the-brachycephalic-paradox">The brachycephalic paradox</h2>



<p>The researchers aimed to understand the so-called "brachycephalic paradox" - why these breeds continue to gain popularity despite well-documented welfare issues, high veterinary costs, and shorter lifespans.&nbsp;</p>



<p>"The focus of this paper is the ‘kindchenschema’ effect (also known as the cute effect); a well-studied phenomenon in psychological research in which infantile features in images of both children and animals are regularly found to provoke positive and affectionate feelings in human observers, and to prompt careful and nurturant behaviors," wrote the study authors.</p>



<p>"Our aim here is to discover whether relative muzzle shortening across a range of dog breeds is linked to the key facial features known to be appealing to, and to elicit nurturant behaviors in, human observers."&nbsp;</p>



<p>"Specifically, we sought to discover whether muzzle shortening in the sagittal plane of dogs’ heads (i.e. in profile) is statistically associated with known ‘kindchenschema’ features in the coronal plane (i.e. fronto-facial features such as the relative size of eyes and forehead)."</p>



<h2 class="wp-block-heading" id="h-how-the-research-was-conducted-nbsp">How the research was conducted&nbsp;</h2>



<p>The team used a unique experiment to compare 30 flat-faced dogs, including 15 English bulldogs and 15 French bulldogs, and 13 Hungarian Mudis, a breed with mid-length muzzles.</p>



<p>The dogs were presented with three boxes with different opening mechanisms, each containing a sausage.&nbsp;</p>



<p>The animals had two minutes to open the boxes while both the experimenter and the owner stood out of direct sight.&nbsp;</p>



<h2 class="wp-block-heading" id="h-what-the-researchers-learned-nbsp">What the researchers learned&nbsp;</h2>



<p>Interestingly, Mudis were much more adept at solving the task, but the brachycephalic breeds were 4.5 times more likely to look back at the human observers for help.</p>



<p>This suggests that short-faced dogs have a tendency to seek out human assistance when faced with problems. As a result, the dogs may be perceived as helpless - forging a stronger bond with their owners.&nbsp;</p>



<h2 class="wp-block-heading" id="h-the-kindchenschema-effect">The kindchenschema effect</h2>



<p>Furthermore, the assistance-seeking behavior of these dogs seems to be tied to the kindchenschema effect, just as the researchers had hypothesized.</p>



<p>The experts also confirmed that the short muzzle length in brachycephalic dogs correlates with more infant-like facial proportions.</p>



<h2 class="wp-block-heading" id="h-basic-human-instincts">Basic human instincts</h2>



<p>Despite the public's understanding of the adverse health impacts, the study suggests that the innate human tendency to care for creatures that appear helpless or childlike may override cognitive reasoning.&nbsp;</p>



<p>The behaviors of flat-faced dogs that people interpret as helplessness and help- seeking - together with childlike looks - seem to activate our basic nurturing instinct.</p>



<p>"Humans find it very difficult to cognitively override strong instinctive predispositions and still choose brachycephalic breeds, disregarding future health and welfare issues," wrote the researchers.</p>



<h2 class="wp-block-heading" id="h-paradoxical-appeal-nbsp">Paradoxical appeal&nbsp;</h2>



<p>This brings to light the ethical dilemma surrounding the demand for these breeds. While their "cute" features may be compelling, they also set the stage for a range of health problems.</p>



<p>"Recent research has indicated that many owners understand that brachycephalia can have adverse consequences for health but choose to keep such breeds anyway," wrote the researchers.</p>



<p>"This may be partly due to the perceived positive behavioral traits of some of these breeds, with owners’ denial of their dogs’ health problems, or with the paradoxical appeal of disabled dogs."&nbsp;</p>



<p>"Either way, there is little doubt that some aspects of the appearance of brachycephalic animals is also a crucial driver of ownership."</p>



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



<p>The study forces us to confront questions about responsible pet ownership and ethical breeding practices.&nbsp;&nbsp;</p>



<p>Going forward, increased awareness and education are crucial for prospective pet owners to make informed decisions that consider the well-being of these beloved animals.</p>



<p>The research is published in the journal <a href="https://www.nature.com/articles/s41598-023-41229-8#:~:text=Owners%20might%20interpret%20these%20behaviours,eliciting%20caring%20behaviour%20in%20owners." target="_blank" rel="noreferrer noopener"><em>Nature</em></a>.</p>

Flat-faced dogs are so popular because they have childlike traits

A recent study from Eötvös Loránd University has explored the...

<p>World Gorilla Day marks its 7th anniversary today, pushing for greater awareness and investment in gorilla conservation.</p>



<p>Since its inauguration in 2017, World Gorilla Day has served as a focal point for people worldwide to celebrate these magnificent creatures and commit to their protection. </p>



<p>While it is clear that collective action and awareness-raising have been making a difference, much more work remains to be done.</p>



<h2 class="wp-block-heading" id="h-the-legacy-of-dian-fossey">The legacy of Dian Fossey</h2>



<p>The celebration of World Gorilla Day coincides with the 50th anniversary of the Karisoke Research Center, founded by the late primatologist Dian Fossey.&nbsp;</p>



<p>As the longest-running gorilla field study site, Karisoke continues to focus on the research, conservation, and protection of gorillas in Africa. However, despite the dedication of numerous organizations and individuals, there is a need for increased investment and public awareness to bolster the survival chances for gorillas.</p>



<h2 class="wp-block-heading" id="h-critical-state-of-mountain-gorillas">Critical state of mountain gorillas</h2>



<p>The mountain gorilla, living in high-altitude mountain and bamboo forests, remains critically endangered. With just around 880 of them left in the wild, their habitat is constantly threatened by human activities.&nbsp;</p>



<p>For example, mining for coltan, a mineral used in small electronic devices, has led to significant habitat destruction in the eastern Democratic Republic of Congo, displacing or even killing gorillas.</p>



<h2 class="wp-block-heading" id="h-recycle-old-cell-phones">Recycle old cell phones</h2>



<p>The annual “Gorillas on the Line…Answer the Call” campaign focuses on recycling small electronic devices to decrease the demand for coltan and preserve gorilla habitats.&nbsp;</p>



<p>Recycling old cell phones and other devices helps reduce the negative impact of coltan mining on gorilla habitats.</p>



<h2 class="wp-block-heading" id="h-help-support-virunga-national-park">Help support Virunga National Park</h2>



<p>Protecting gorillas in conflict zones, particularly in Virunga National Park, is a monumental task that requires the tireless efforts of over 770 Rangers. Their unyielding spirit and determination are a testament to the significance of conserving this endangered species.</p>



<p>Over the past year, the security situation at Virunga National Park has become extremely dangerous, with rebel groups controlling the Park’s southern sector – an area which spans the endangered mountain gorilla habitat and Park headquarters. </p>



<p>"Tragically, ten of our brave Rangers have lost their lives in unprovoked attacks in 2023 alone," the park said on its <a href="https://virunga.org/" target="_blank" rel="noreferrer noopener">website</a>. "With the support of local communities, dedication of our Rangers and adoption of new technologies, we are persisting in our efforts to preserve the Park’s rich biodiversity."</p>



<p><a href="https://virunga.org/support-us/donate/#:~:text=Over%20the%20past%20year%2C%20the,unprovoked%20attacks%20in%202023%20alone." target="_blank" rel="noreferrer noopener">Your donation</a> will help us stand strong in the midst of these challenging circumstance.</p>



<h2 class="wp-block-heading" id="h-adopt-a-gorilla">Adopt a gorilla</h2>



<p>World Wildlife Fund (WWF) provides us with the opportunity to symbolically <a href="https://gifts.worldwildlife.org/gift-center/gifts/Species-Adoptions/Gorilla.aspx?sc=AWY2204OQ19293A01785RX&amp;gad=1&amp;gclid=Cj0KCQjwvL-oBhCxARIsAHkOiu1Re3bdC-CalTNUixRz80rUioRz6FHZwKsfYJTd5pgGOe5egKnUikMaAgL6EALw_wcB" target="_blank" rel="noreferrer noopener">adopt a gorilla</a> to support their conservation efforts. </p>



<p>"For more than 60 years, WWF has been protecting the future of nature. WWF works in nearly 100 countries and is supported by 1.3 million members in the United States and more than 5 million members globally," the organization says on its website.&nbsp;</p>



<p>"Your donation provides general support and makes you a member. 83% of spending is directed to worldwide conservation activities."</p>



<h2 class="wp-block-heading" id="h-more-about-gorillas">More about gorillas</h2>



<p>Gorillas are the largest of the great apes and are divided mainly into two species: the Eastern gorilla and the Western gorilla. Each of these species has two subspecies.&nbsp;</p>



<ul>
<li>Eastern gorilla: The subspecies are the Mountain gorilla and the Eastern Lowland gorilla.&nbsp;</li>



<li>Western gorilla: The subspecies are the Western Lowland gorilla and the Cross River gorilla.</li>
</ul>



<h3 class="wp-block-heading" id="h-habitat">Habitat</h3>



<p>Mountain gorillas are found in the cloud forests of Central Africa, specifically in Uganda, Rwanda, and the Democratic Republic of Congo. They live at elevations ranging from 8,000 to 13,000 feet.&nbsp;</p>



<p>Western Lowland gorillas inhabit the rainforests of Central and West Africa, including countries like Gabon, Cameroon, and the Republic of the Congo.</p>



<h3 class="wp-block-heading" id="h-social-structure-and-behavior">Social structure and behavior</h3>



<p>Gorillas live in groups called troops, which typically consist of one dominant male, known as the silverback, along with multiple females and their offspring. The silverback serves as the protector and decision-maker of the troop.&nbsp;</p>



<p>Gorillas communicate through vocalizations, body postures, and facial expressions. Their social structure is remarkably intricate, built on strong family ties and relationships.</p>



<h3 class="wp-block-heading" id="h-diet">Diet</h3>



<p>Gorillas are primarily herbivorous, relying on leaves, shoots, and stems as their main food sources. They also eat fruits, small insects, and, occasionally, small vertebrates. Their diet varies by habitat and availability of food sources.</p>



<h3 class="wp-block-heading" id="h-threats-and-conservation-efforts">Threats and conservation efforts</h3>



<p>The survival of gorillas is increasingly threatened due to habitat loss, poaching, and disease. For instance, diseases transmitted by humans, such as respiratory infections, have become a significant concern. Illegal hunting for bushmeat and capture for the illegal pet trade also puts pressure on gorilla populations.</p>



<p>Efforts to conserve gorillas include establishing and maintaining national parks and reserves, implementing anti-poaching measures, and community engagement programs to encourage local populations to become stewards of gorilla conservation. Initiatives like World Gorilla Day play a crucial role in raising awareness and funds.</p>



<h3 class="wp-block-heading" id="h-ecosystem-health">Ecosystem health</h3>



<p>Gorillas have a multifaceted role in maintaining the health and stability of their ecosystems. Their decline or extinction would have cascading effects, potentially leading to reduced biodiversity, compromised forest health, and weakened ecosystem services, emphasizing the importance of their conservation.</p>



<h4 class="wp-block-heading" id="h-seed-dispersal">Seed dispersal</h4>



<p>Gorillas have a primarily vegetarian diet, which includes a variety of fruits. After consuming these fruits, they excrete the seeds in different locations. This seed dispersal is vital for forest regeneration and increasing plant diversity. Many of the plants they consume rely on gorillas to help their seeds spread and germinate.</p>



<h4 class="wp-block-heading" id="h-nutrient-recycling">Nutrient recycling</h4>



<p>By feeding on vegetation and subsequently excreting waste, gorillas play a part in recycling vital nutrients in the forest ecosystem. Their waste enriches the soil, promoting plant growth.</p>



<h4 class="wp-block-heading" id="h-forest-health-and-dynamics">Forest health and dynamics</h4>



<p>Gorillas, particularly the Western Lowland gorilla, are known to clear vegetation in areas where they nest each night. This seemingly small act has a cumulative effect, creating clearings in forests that allow new plants to grow and letting sunlight penetrate deeper into the forest. This dynamic action affects forest composition and structure over time.</p>



<h4 class="wp-block-heading" id="h-control-of-herbivore-populations">Control of herbivore populations</h4>



<p>While gorillas are herbivores, their presence can influence the density and behavior of other herbivorous animals in the ecosystem due to competition for food resources.</p>



<h4 class="wp-block-heading" id="h-bioindicator-species">Bioindicator species</h4>



<p>Gorillas, being at the top of their food chain and reliant on a specific habitat, can serve as an indicator of the overall health of their ecosystem.&nbsp;</p>



<p>If gorilla populations are thriving, it often indicates that the lower levels of the food chain are in balance and that the habitat is healthy. Conversely, declining gorilla populations might indicate problems in the ecosystem.</p>



<h4 class="wp-block-heading" id="h-economic-and-cultural-importance">Economic and cultural importance</h4>



<p>While not a direct ecological role, gorillas play a crucial role in the local economy and culture of regions where they inhabit.&nbsp;</p>



<p>Gorilla trekking and ecotourism attract thousands of visitors, providing significant revenue and jobs. These tourism activities often fund conservation projects which benefit not only the gorillas but the broader ecosystem.</p>



<p>As we celebrate World Gorilla Day, it is essential to recognize their intrinsic value as unique and complex creatures, as well as their significance to ecosystems. The plight of the gorilla is more than a conservation issue; it is a call to uphold the interconnectedness of life on Earth.</p>

World Gorilla Day: Supporting the guardians of the forest

World Gorilla Day marks its 7th anniversary today, pushing for...

Photo,Of,A,Red-crowned,Amazon,amazona,Viridigenalis

<p>The endangered red-crowned parrot species is flourishing in the urban expanses of South Texas. This surprising discovery lies contrary to the usual detrimental impact of urban development on most animal species.</p>



<p>These vibrant birds have remarkably adapted to urban life despite widespread deforestation, pollution, and the illicit pet trade relocating them from their native habitats. The study was helmed by a <a href="https://www.tamu.edu/index.html" target="_blank" rel="noreferrer noopener">Texas A&amp;M</a>-led research team, co-authored by Dr. Donald J. Brightsmith and graduate student Simon Kiacz.</p>



<h2 class="wp-block-heading" id="h-unexpected-urban-dwellers">Unexpected urban dwellers</h2>



<p>Red-crowned parrots are characterized by their predominantly green plumage and distinctive cluster of red feathers on their heads. They originally inhabited a compact region in Northeastern Mexico. Due to rampant habitat destruction and illicit poaching, their existence is under severe threat in their native lands. </p>



<p>This fact makes their proliferation in urban Texas all the more extraordinary. The unauthorized trade often involves poaching of eggs or fledglings, later sold at exorbitant prices.</p>



<p>Simon Kiacz noted, "Parrots are popular pets in places like South Texas and Latin America.” The lack of awareness regarding their protected status, even among law enforcement, is alarming. It’s crucial to note that the animal trade has significantly contributed to the red-crowned parrots’ presence in Texas, with many being brought over legally in the 1980s.</p>



<h2 class="wp-block-heading" id="h-texas-embraces-red-crowned-parrots">Texas embraces red-crowned parrots</h2>



<p>Texas has embraced these fascinating birds, awarding them native species status which is pivotal for their protection. Dr. Brightsmith highlighted the importance of this status, stating, “Without native species status, it would be much more difficult to provide protection for the species.” </p>



<p>This acknowledgment spurred interest from <a href="https://tpwd.texas.gov/" target="_blank" rel="noreferrer noopener">Texas Parks &amp; Wildlife</a>, paving the way for extensive research on the adaptation and well-being of these parrots in South Texas.</p>



<h2 class="wp-block-heading" id="h-mapping-the-path-to-conservation">Mapping the path to conservation</h2>



<p>The research team meticulously counted and mapped the parrots, concentrating especially on the Rio Grande Valley. Remarkably, places like Brownsville have adopted the red-crowned parrot as their official mascot. </p>



<p>With around 900 parrots residing in South Texas, Kiacz and his team closely monitored their breeding activity. These observations have provided a comprehensive insight into their thriving population.</p>



<h2 class="wp-block-heading" id="h-symbiotic-urban-adaptation">Symbiotic urban adaptation</h2>



<p>The adaptation and thriving of red-crowned parrots in urban environments are unusual. The species, deemed as “synanthropes,” coexists harmoniously with human-made environments. Kiacz explains, “Humans have basically created the perfect environment for these parrots.” </p>



<p>The relationship stems from their mutual liking for well-watered, ornamental plants producing fruit and seeds year-round. Even the propensity to plant non-native palm trees has inadvertently provided perfect nesting cavities for these parrots, further solidifying their urban adaptation.</p>



<h2 class="wp-block-heading" id="h-coexisting-with-red-crowned-parrots">Coexisting with red-crowned parrots</h2>



<p>Despite their flourishing existence and negligible competition with local species for food, the parrots’ noise levels have been the sole inconvenience to the locals. The researchers hope that their findings will usher in heightened awareness and improved conservation efforts. They stress the importance of understanding and accepting these birds as part of the urban environment.</p>



<p>Kiacz emphasized the need for communal harmony stating, “the best help we can give these parrots is to teach people how to live with parrots as neighbors.” For instance, maintaining a dead, yet safe tree can provide nesting spaces for these parrots, fostering a symbiotic coexistence.</p>



<p>Brightsmith and Kiacz are currently delving deeper. They are studying the intricate relationships between red-crowned parrots and their sister species, exploring potential natural hybridization and its conservation implications.</p>



<p>In summary, the thriving existence of red-crowned parrots amidst urban sprawl is a testament to nature's resilience and adaptability. It opens up a plethora of opportunities for research and provides a unique perspective on urban conservation strategies, emphasizing the balance between urban expansion and biodiversity. </p>



<p>The exploration of harmonious coexistence and continued conservation efforts are essential steps towards protecting these vibrant beings, allowing them to continue being our colorful neighbors in the urban jungle.</p>



<p>This study was <a href="https://www.mdpi.com/1424-2818/15/7/878" target="_blank" rel="noreferrer noopener">recently published</a> in the scientific journal <em>Diversity</em>.</p>

<p>Recent research discovered that over 10% of English river sites contain hazardous levels of pesticides that are toxic to bees and also prohibited by the European Union (EU). </p>



<p>The alarming levels of neonicotinoids, particularly in rivers in the east of England, South East, and West Midlands, expose severe environmental concerns and potential risks to aquatic life and human health.</p>



<h2 class="wp-block-heading" id="h-damaging-presence-of-neonicotinoids">Damaging presence of neonicotinoids</h2>



<p>Of the 283 river sites that underwent examination by the Environment Agency between 2020 and 2022, at least one of the five neonicotinoids was present in 29. It is distressing to note that 55% of these 29 sites exhibited one or more neonicotinoids above the <a href="https://echa.europa.eu/environmental-quality-standards" target="_blank" rel="noreferrer noopener">Environmental Quality Standard</a> (EQS) set by the EU, deemed safe for aquatic species. Furthermore, over four times the acceptable limit of one or more pesticides marked 21% of the sites.</p>



<p>The research brought to light the presence of clothianidin, imidacloprid, and thiamethoxam. These pesticides, banned in the UK since 2018 for outdoor crops, are notorious for their harmful impacts on <a href="https://www.earth.com/news/omega-3-oil-may-help-protect-pollinators-from-pesticides/" target="_blank" rel="noreferrer noopener">bees</a> and aquatic organisms. </p>



<p>Thiacloprid and Acetamiprid were also identified. The former was prohibited in 2020 due to potential detrimental effects on human health, while the latter, still allowed in the UK, is known to accumulate and damage various living organisms.</p>



<h2 class="wp-block-heading" id="h-areas-with-highest-concentrations">Areas with highest concentrations</h2>



<p>The east of England, the West Midlands, and Yorkshire and Humber showcased the highest concentrations of neonicotinoids at single sites. The rivers Ivel, Nene, Ouse, Tame, and Waveney in these regions were the most prevalent for pesticide use.</p>



<p>Tessa Wardley, the Director of Communications and Advocacy at the <a href="https://theriverstrust.org/" target="_blank" rel="noreferrer noopener">Rivers Trust</a>, emphasized the likely understatement of the actual extent of neonicotinoid pollution in English rivers due to infrequent and inadequate monitoring by the <a href="https://www.gov.uk/government/organisations/environment-agency" target="_blank" rel="noreferrer noopener">Environment Agency</a>, especially during wet weather when the risk of rapid flushing of pesticides into rivers is heightened.</p>



<h2 class="wp-block-heading" id="h-controversy-and-debate">Controversy and debate</h2>



<p>This revelation coincides with ongoing debates within the government regarding the renewal of the usage of thiamethoxam for the fourth consecutive year. This debate has sparked controversy due to previous emergency authorizations contradicting expert counsel. </p>



<p>The EU Court of Justice, in January 2023, deemed such emergency authorizations of seeds treated with banned neonicotinoids as violations of EU law.</p>



<p>Nick Mole, Policy Officer at Pesticide Action Network UK, termed the findings as “hugely concerning,” urging the UK government to put a halt to ‘emergency’ extensions for the use of <a href="https://www.earth.com/news/neonicotinoids-kill-bees-and-threaten-hundreds-of-species/" target="_blank" rel="noreferrer noopener">banned pesticides</a> and to institute a robust and well-funded monitoring system for all UK water bodies urgently.</p>



<p>Barnaby Coupe, Land Use Policy Manager at The Wildlife Trusts, also criticized the UK government's ongoing approval of toxic pesticides, which he claims has ignored scientific findings and expert advice, resulting in a significant reduction in wildlife.</p>



<h2 class="wp-block-heading" id="h-government-actions">Government actions</h2>



<p>In response, a spokesperson for the Department for Environment, Food, and Rural Affairs (DEFRA) assured that their comprehensive Plan for Water is addressing every source of pollution through enhanced investment, stricter regulation, and tougher enforcement. </p>



<p>They further highlighted the government's commitment to minimizing the risks and impacts of pesticides and reducing the use of insecticides by farmers through increased funding and sustainable farming incentives.</p>



<p>In summary, the new research has sparked renewed urgency and concern regarding the hazardous levels of prohibited pesticides in English rivers, revealing the far-reaching impacts on wildlife, aquatic life, and potentially human health. </p>



<p>The government is under increased pressure to enhance monitoring, regulation, and enforcement to combat the rising levels of harmful pesticides and to reconsider the allowances and extensions granted for the use of such chemicals in the agriculture sector.</p>

Concerning levels of bee-harming pesticides discovered in English rivers

<p>Traces of ancient proteins found in fossilized dinosaur feathers may shed new light on the evolution of feathers, according to a study from <a href="https://www.ucc.ie/">University College Cork</a>.</p>



<p>The research was led by Dr. Tiffany Slater and Professor Maria McNamara of UCC’s School of Biological, Earth, and Environmental Science. The experts collaborated with scientists based at Linyi University and the Stanford Synchrotron Radiation Lightsource.&nbsp;</p>



<h2 class="wp-block-heading" id="h-fossil-proteins">Fossil proteins</h2>



<p>"Fossil proteins are valuable tools in evolutionary biology. Recent technological advances and better integration of experimental methods have confirmed the feasibility of biomolecular preservation in deep time, yielding new insights into the timing of key evolutionary transitions," wrote the researchers.&nbsp;</p>



<h2 class="wp-block-heading" id="h-focus-of-the-study">Focus of the study</h2>



<p>The team analyzed 125-million-year-old feathers from the dinosaur Sinornithosaurus and the early bird Confuciusornis from China, in addition to a 50-million-year-old feather from the United States.</p>



<p>While previous research indicated that modern feathers have a different composition than ancient feathers, the new study reveals that they share the same protein composition.&nbsp;</p>



<p>According to the experts, this confirms that the chemistry of feathers originated much earlier than previously thought.&nbsp;</p>



<h2 class="wp-block-heading" id="h-beta-proteins-nbsp">Beta-proteins&nbsp;</h2>



<p>“It’s really exciting to discover new similarities between dinosaurs and birds,” said Dr. Slater.&nbsp;</p>



<p>“To do this, we developed a new method to detect traces of ancient feather proteins. Using X-rays and infrared light we found that feathers from the dinosaur Sinornithosaurus contained lots of beta-proteins, just like feathers of birds today.”&nbsp;</p>



<p>The team ran experiments to investigate how feather proteins break down during the fossilization process. This helped the experts interpret the chemical signals preserved in the fossil feathers.</p>



<h2 class="wp-block-heading" id="h-weird-chemistry">Weird chemistry</h2>



<p>“Modern bird feathers are rich in beta-proteins that help strengthen feathers for flight,” said Dr. Slater.&nbsp;&nbsp;</p>



<p>“Previous tests on dinosaur feathers, though, found mostly alpha-proteins. Our experiments can now explain this weird chemistry as the result of protein degradation during the fossilization process."&nbsp;</p>



<p>"So although some fossil feathers do preserve traces of the original beta-proteins, other fossil feathers are damaged and tell us a false narrative about feather evolution.”&nbsp;</p>



<p>The researchers noted that experiments show that feather beta-proteins can survive moderate thermal maturation. "As predicted by our experiments, analyses of Mesozoic feathers confirm that evidence of feather CBPs can persist through deep time," they wrote.</p>



<p>“Traces of ancient biomolecules can clearly survive for millions of years, but you can’t read the fossil record literally because even seemingly well-preserved fossil tissues have been cooked and squashed during fossilization," said study senior author Professor Maria McNamara.</p>



<p>"We’re developing new tools to understand what happens during fossilization and unlock the chemical secrets of fossils. This will give us exciting new insights into the evolution of important tissues and their biomolecules. “</p>



<p>The research is published in the journal <a href="http://dx.doi.org/10.1038/s41559-023-02177-8"><em>Nature Ecology and Evolution</em></a>.</p>
