Fish populations tend to do better in places where rigorous fisheries management practices are used, and the more measures employed, the better for fish populations and food production, according to a new paper published Jan. 11 in Nature Sustainability.
In what may be a sign of climate-change-induced conflict, researchers have captured rare photographic evidence of a jaguar killing another predatory wild cat at an isolated waterhole in Guatemala.
A rare study shows how one of Georgia’s barrier islands provides a safe haven for gopher tortoises and gives researchers at the University of Georgia evidence to prove species relocation is an effective conservation tool.
A new study, ‘150 million years of sustained increase in pterosaur flight efficiency’, published in the journal Nature has shown that pterosaurs – a group of creatures that became Earth’s first flying vertebrates – evolved to improve their flight performance over their 150 million-year existence, before going extinct at the same time as dinosaurs 66 million years ago.
Scientists from the University of Bristol and the Royal Veterinary College have discovered how birds are able to fly in gusty conditions – findings that could inform the development of bio-inspired small-scale aircraft.
MADISON – Ecologists at the University of Wisconsin–Madison have found that carnivores living near people can get more than half of their diets from human food sources, a major lifestyle disruption that could put North America’s carnivore-dominated ecosystems at risk.
Scientists report evidence of a hibernation-like state in Lystrosaurus, an animal that lived in Antarctica during the Early Triassic 250 million years ago. The fossils are the oldest evidence of a hibernation-like state in a vertebrate, and indicate that torpor arose in vertebrates even before mammals and dinosaurs evolved.
A study by WCS and partners produced new analyses to pinpoint the most important forests for biodiversity conservation remaining in Central Africa.
Infertility is a worldwide clinical problem for human health that affects 8 to 12 percent of couples. A new study from Washington University in St. Louis has implications for understanding some age-related aspects of male reproductive health in primates, including humans. Older male rhesus monkeys sire fewer offspring, even though they appear to be mating as much as younger monkeys with similarly high social status.
A new study published in the journal PLOS ONE finds graying hair is not indicative of a chimpanzee’s age.
MERMAID, an open-source tech platform for marine scientists, is for the first time launching an interactive map that provides an insider’s view of the ecosystem data collected from coral reefs by field scientists around the world.
A new global study has found that only 2.5 percent of tropical reefs are formally protected and conserved through laws and regulations. These numbers are significantly lower than previous estimates, and highlight an urgent need for governments, communities, and partnering organizations to create and expand marine reserves to protect these ecosystems which support more than 500 million people worldwide.
The Wildlife Conservation Society (WCS) released a photo today of a single Asiatic wild ass or khulan (Equus hemionus hemionus) crossing a previously impenetrable barrier along the Trans Mongolian Railroad – the first known crossing by this near-threatened species into the eastern steppe in 65 years.
There is a world of life on the backs of loggerhead sea turtles, and it’s more abundant and diverse than scientists knew. An international team led by Florida State University researchers found that more than double the number of organisms than previously observed live on the shells of these oceanic reptiles, raising important questions about loggerhead sea turtle ecology and conservation.
Aerial drone footage provides the first evidence of adult blacktip sharks using shallow waters as a refuge from a huge predator – the great hammerhead. Before this study, documentation of adult sharks swimming in shallower waters to avoid predation did not exist. Unmanned aerial vehicles enable scientists to unobtrusively observe behaviors in the wild, providing insight into seldom-seen predator-prey interactions. When it comes to sharks, this “hammerhead” time video proves you “can’t touch this.”
University of Washington researchers have discovered that large predators play a key yet unexpected role in keeping smaller predators and deer in check. Their “fatal attraction” theory finds that smaller predators are drawn to the kill sites of large predators by the promise of leftover scraps, but the scavengers may be killed themselves if their larger kin return for seconds.
A team of researchers from the University of Georgia and San Diego State University has found that the practice of feeding wildlife could be more detrimental to animals than previously thought.
Researchers at Ohio University have published a new study in collaboration with Ugandan scientists, cautioning that humans place endangered mountain gorillas at risk of disease transmission during tourism encounters.
Teach a chimpanzee to fish for insects to eat, and you feed her for a lifetime. Teach her a better way to use tools in gathering prey, and you may change the course of evolution.For most wild chimpanzees, tool use is an important part of life — but learning these skills is no simple feat. Wild chimpanzees transfer tools to each other, and this behavior has previously been shown to serve as a form of teaching.
A new study by a team of Russian and American scientists revealed the first-ever detailed analysis of a tigress from the birth of her cubs through their first four months.
Psychologist observing two chimpanzees in a zoo have discovered that they performed a behaviour hitherto never seen, they coordinated together in a rhythmic social ritual.
A new study in the journal PLOS One says Glacier National Park’s iconic mountain goats are in dire need of air conditioning.
On a typical June day in Yellowstone, it's not unusual to see hundreds of bison grazing in the Lamar Valley.
A group of international conservationists is urging governments across the globe to adopt a new approach to address the impact of economic development on the natural world.
Emperor penguins are some of the most striking and charismatic animals on Earth, but a new study from the Woods Hole Oceanographic Institution (WHOI) has found that a warming climate may render them extinct by the end of this century. The study, which was part of an international collaboration between scientists, published Nov. 7, 2019, in the journal Global Change Biology.
Amazonia is home to the greatest number of species on earth, many now threatened, but a new study published October 22 in the open-access journal PLOS Biology by Jason Weir from the University of Toronto and Trevor Price from the University of Chicago hammers home Amazonia’s importance, showing that it is not only a place with many species, but one where it has taken an exceptionally long time for new species to form.
The fabled use of canaries in coal mines as an early warning of carbon monoxide stemmed from the birds' extreme sensitivity to toxic conditions compared to humans.
The Wildlife Conservation Society (WCS) and Pueblo of Pojoaque will co-host a conference to advance a bold vision: rewilding the North American continent with the American bison.
With the help of new technologies, a team led by the University of Washington has confirmed that piranhas lose and regrow all the teeth on one side of their face multiple times throughout their lives. How they do it may help explain why the fish go to such efforts to replace their teeth.
Wilderness areas, long known for intrinsic conservation value, are far more valuable for biodiversity than previously believed, and if conserved, will cut the world’s extinction risk in half, according to a new study published in the journal Nature.
Most of the pups born in an elephant seal colony in California over a span of five decades were produced by a relatively small number of long-lived "supermoms", according to a new study by researchers at the University of California, Santa Cruz.
Adaptations could have allowed these kangaroos to eat tougher foods than any living Australian herbivores
An international team of scientists, led by researchers at McMaster University, has solved a centuries-old mystery of ‘Fraser’s Clawed Frog’, an unusual and elusive species found in West Africa.
Sponsored by the university’s Center for Bat Research, Outreach, and Conservation, the free event’s theme this year is “Always Hanging Out! The Busy Social Lives of Bats,” focusing on bat social networks and behaviors.
Researchers at McMaster University who rush in after storms to study the behaviour of spiders have found that extreme weather events such as tropical cyclones may have an evolutionary impact on populations living in storm-prone regions, where aggressive spiders have the best odds of survival.
The largest study ever conducted of its kind has identified where and how to save coral reef communities in the Indo-Pacific, according to an international group of scientists from WCS (Wildlife Conservation Society) and other conservation NGOs, government agencies, and universities. The study outlines three viable strategies that can be quickly enacted to help save coral reefs that are threatened by climate change and human impacts.
An autonomous underwater vehicle (AUV) known as the REMUS SharkCam has been used in the UK for the first time to observe the behavior of basking sharks in the Inner Hebrides, off the west coast of Scotland.
A study that looks at how temperature influences the development of painted turtles may lead biologists to rethink the theoretical frameworks they use when analyzing the topic. The study, led by an Iowa State scientist, found wide variation within local populations, suggesting temperature sensitivity of embryonic development can vary significantly from one turtle nest to another within a single population.
Recent surveys of the population of endangered Bornean orangutans in Sabah, the Malaysian state in the north-east of Borneo, show mixed results. Populations have remained stable within well-managed forests
Like most megaherbivores, this species can have important effects on ecosystems and biogeochemical cycles. Yet, the influence of elephants on the structure, productivity and carbon stocks in Africa’s rainforests has been largely unknown; until now.
New research on the evolutionary relationships between tree sloths and their extinct giant relatives is challenging decades of widely accepted scientific research.
A distinct strain of canine distemper virus, which is a widespread virus of importance to wildlife and domesticated dogs, has been identified in wild animals in New Hampshire and Vermont, according to pathologists with the New Hampshire Veterinary Diagnostic Lab at the University of New Hampshire. No virus in this distinct subgroup of canine distemper virus has yet been reported in a domesticated dog.
In a paper published May 2 in Nature Communications, a University of Washington team reports that two major forces have shaped bat skulls over their evolutionary history -- echolocation and diet -- generating a huge diversity of skull shapes across more than 1,300 bat species today.
Findings support idea that dogs helping pack members is ancestral tendency, and not due to domestication
An international study published today in the journal Science argues that the current international target for the protected area estate, accepted by over 190 nations, is failing. They propose a new measurable target based on the best scientific evidence that they say will galvanize greater and more effective conservation efforts.
A sweeping new study published in the journal Science says that chimpanzee’s complex cultures – including the use of tools and other behaviors – are being lost as human disturbance expands into previously wild areas.
