Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.

Our increasing demand for metals and minerals is putting over four thousand vertebrate species at risk, with the raw materials needed for clean energy infrastructure often located in global biodiversity hotspots, a study has found.

Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.

Researchers have found New Zealand's endangered flightless birds are seeking refuge in the locations where six species of moa last lived before going extinct.

Brachiopods were evolving in new directions but this did not turn into evolutionary success in terms of the numbers of species, researchers have found.

We all know what it's like when the penny suddenly drops. Animals too experience such moments of insight. They could prove useful for research of consciousness.

Rock art explored by archaeologists in the Colombian Amazon has provided an insight into the complex relationship between the earliest settlers on the continent and the animals they encountered.

Mammals that have evolved more developed brains tend to have a smaller size difference between males and females of that species, according to new research.

Over the last century, a once-deadly mosquito-borne virus has evolved so that it no longer sickens humans. New research shows that changes in the virus's ability to target human cells paralleled the decline in illness and death. The findings offer important lessons in virology that may help guide better preparedness for future outbreaks of other viral diseases.

Hens fluff their head feathers and blush to express different emotions and levels of excitement, according to a new study.

Researchers conducted a breakthrough proof-of-concept study that found an HIV-like virus particle that could cease the need for lifelong medications.

Sometimes less is more. Researchers accurately modeled dynamic fish schooling by incorporating the tendency of fish to focus on a single visual target instead of the whole school, as well as other visual cues.

Researchers have captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.

Scientists have discovered that the serrated edges of Komodo dragons' teeth are tipped with iron. The study gives new insight into how Komodo dragons keep their teeth razor-sharp and may provide clues to how dinosaurs like Tyrannosaurus rex killed and ate their prey.

A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests.

World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists. Without this, work on tackling either crisis could inadvertently harm progress on the other.

Biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. A study based on labor-intensive fieldwork and analysis in tropical mountain regions shows that a warmer and drier climate will lead to massive losses of plant species.

Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research.

People's moral values could limit their uptake of lab-grown meat, a study suggests. People who say living a natural life is morally important to them are more likely to reject lab-grown meat -- also known as cultured or cultivated meat -- than those who do not, research shows.

A pioneering study has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. The study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.
