Climate is most important factor in where mammals choose to live, study finds      (via sciencedaily.com)     Original source 

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.

The ancestor of all modern birds probably had iridescent feathers      (via sciencedaily.com)     Original source 

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.

How evolution tamed a deadly virus and why we should still worry      (via sciencedaily.com)     Original source 

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.

See less to move better: Dynamic schooling of fish by visual selection and focus      (via sciencedaily.com)     Original source 

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.

Morals are key to consumer views on lab-grown meat, study finds      (via sciencedaily.com)     Original source 

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.

The most endangered fish are the least studied      (via sciencedaily.com)     Original source 

The most threatened reef fishes are also the most overlooked by scientists and the general public. Scientists measured the level of human interest in 2,408 species of marine reef fish and found that the attention of the scientific community is attracted by the commercial value more than the ecological value of the fishes. The public, on the other hand, is primarily influenced by the aesthetic characteristics of certain species, such as the red lionfish (Pterois volitans) and the mandarinfish (Synchiropus splendidus).

Logged forests can still have ecological value -- if not pushed too far      (via sciencedaily.com)     Original source 

Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.
