University of Queensland research has found despite considerable conservation efforts, the illegal killing of critically endangered orangutans on Borneo may be an ongoing threat to the species.
Predators must eat to survive — and to survive, prey must avoid being eaten. One theory, the Wolf-Mangel model, suggests predators could use false attacks to tire prey out or force them to take bigger risks, but this has been hard to show in practice.
Named after its habitat preference, Paroedura manongavato, from the Malagasy words “manonga” (to climb) and “vato” (rock), is a bouldering expert. Part of its “home range” is also very well-known to rock climbers for its massive granitic domes.
Tens of thousands of endangered sharks and rays are caught by small-scale fisheries off the Republic of the Congo each year, new research shows.
It's tough to catch the eye of a potential mate when you’re dressed all in black with no fancy feathers to jiggle around. But a tiny bird called the Blue-black Grassquit has found a way. Learn about this fascinating species during the 2023 Paul C. Mundinger Distinguished Lectureship presented by the Cornell Lab of Ornithology.
Killer whales are some of the oceans’ top predators, but even they can be exposed to environmental pollution. In the largest study to date on North Atlantic killer whales, researchers in ACS’ Environmental Science & Technology report the levels of pollutants in 162 individuals’ blubber.
Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research from the University of Georgia’s Savannah River Ecology Laboratory and Warnell School of Forestry and Natural Resources. Within 24 months of the start of control efforts in the study area located around the Savannah River Site in Aiken, South Carolina, researchers found a reduction of about 70% in relative abundance of pigs and a corresponding decline in environmental rooting damage of about 99%.
Porcupines of the genus Coendou are arboreal, herbivorous, nocturnal rodents distributed in tropical and subtropical regions of the Americas.
The “Margaritaville” in Jimmy Buffett’s famous song isn’t a real place, but it’s long been associated with the Florida Keys. This string of tropical islands is home to the only living coral barrier reef in the continental US, along with many animals found nowhere else in the world.
A team of researchers from Queen Mary University of London and the University of Campinas in Brazil has found that tropical forest ecosystems are more reliant on aquatic insects than temperate forest ecosystems and are therefore more vulnerable to disruptions to the links between land and water.
James Stroud, assistant professor in the School of Biological Sciences at the Georgia Institute of Technology, measured natural selection in four Anolis lizard species in the wild for five consecutive time periods over three years.
Diseases are among the major causes of tree mortality in both forests and urban areas. New diseases are continually being introduced, and pathogens are continually jumping to new hosts, threatening more and more tree species.
Researchers at the Francis Crick Institute have shown that pregnancy hormones ‘rewire’ the brain to prepare mice for motherhood.
Palaeontologists at University College Cork (UCC) have found the first molecular evidence of phaeomelanin, the pigment that produces ginger colouration, in the fossil record.

Acoels have been found to host a wide diversity of symbiotic, photosynthetic microalgae.
A new method has been developed for fabricating 3D compound eyes. The technique uses a 3D laser to ablate a curved surface, followed by etching in acid. This method can produce high-quality 3D concave lens arrays that can be used to make soft compound eyes.
Researchers have developed a new method to analyse facial expressions, as part of efforts to better understand animal communication.
This asynchronous beating comes from how the flight muscles interact with the physics of the insect’s springy exoskeleton. This decoupling of neural commands and muscle contractions is common in only four distinct insect groups. For years, scientists assumed these four groups evolved these ultrafast wingbeats separately, but research from the Georgia Institute of Technology and the University of California, San Diego (UC San Diego) shows that they evolved from a single common ancestor. This discovery demonstrates evolution has repeatedly turned on and off this particular mode of flight. The researchers developed physics models and robotics to test how these transitions could occur.
For the first time, big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to nonbreeding grounds, and back north again during spring migration.
Laden with dissolved salt, Antarctic waters can hover just above freezing and even dip below it. Temperatures this low would likely kill the animals that prosper in warmer waters further north. Yet, some creatures have found ways to live in this inhospitable cold.
Gut microbes found in wild wolves may be the key to alleviating a debilitating gastrointestinal condition common to domestic dogs, according to a study led by researchers at Oregon State University – Cascades.
RUDN University biologists and colleagues from Egypt and Saudi Arabia were the first to study the effect of nanoparticles of the natural polymer chitosan on the fish's health in aquaculture. It turned out that chitosan nanogel increases the resistance to a dangerous yeast by 22%. It increases the productivity of fisheries.
A new device, currently being designed by a University of Adelaide PhD candidate, could help to close a loophole currently being exploited by illegal wildlife traffickers.
During a recent review of the U.S. Fish and Wildlife Service’s recovery plans for more than 200 endangered and threatened vertebrate species in the United States, Michigan State University researchers made an interesting discovery.
A Florida State University biologist has proposed a new idea about how animals choose their mates, and mathematical tests suggest that it could challenge the previous understanding into picking partners.
Genetic quality or genetic compatibility? What do female fruit flies prioritize when mating? Researchers at the University of Zurich show that both factors are important at different stages of the reproductive process and that females use targeted strategies to optimize the fitness of their offspring.
Predation is a driving force in the evolution of anti-predator strategies, and death feigning, characterized by immobility in response to threats, is a common defensive mechanism across various animal species.
Sometimes simple solutions are better. It all depends on the nature of the problem. For humpback whales, the problem is the rope connecting a crab trap on the seafloor to the buoy on the surface. And for fishermen, it’s fishery closures caused by whale entanglements.
Recent study sheds new light on the enigmatic early evolution of snakes by examining an unexpected source: their brains. The results emphasise the significance of studying both the soft parts of animals’ bodies and their bones for understanding how animals evolved.
