Local extinction of Southern California mountain lions possible within 50 years

Two isolated mountain lion populations in southern California’s Santa Ana and Santa Monica Mountains are at risk of local extinction, perhaps as soon as within 50 years, according to a study published in the journal Ecological Applications. The extinction risk is due to low genetic diversity and mortality that affects the stability of the population. But increasing connectivity could help.

Evidence rogue waves are getting more extreme

Research suggests that ‘rogue’ waves are occurring less often, but becoming more extreme. Scientists have, for the first time, used long-term data from a wide expanse of ocean to investigate how these rare, unexpected and hazardous ocean phenomena behave.

Review of noise impacts on marine mammals yields new policy recommendations

Marine mammals are particularly sensitive to noise pollution because they rely on sound for so many essential functions, including communication, navigation, finding food, and avoiding predators. An expert panel has now published a comprehensive assessment of the available science on how noise exposure affects hearing in marine mammals, providing scientific recommendations for noise exposure criteria that could have far-reaching regulatory implications.

Coastal ecosystems suffer from upriver hydroelectric dams

Researchers found that inland river dams can have highly destructive effects on the stability and productivity of coastline and estuarine habitats, which provide protection from storms, commercial fishery habitats, and belowground carbon storage.

New study shows human impact erodes chimpanzee behavioral diversity

(San Diego Zoo Global) A research team led by the Max Planck Institute for Evolutionary Anthropology and the German Centre for Integrative Biodiversity Research investigated whether chimpanzee behavioral diversity is reduced when there is high human impact on their habitats. By comparing sets of chimpanzee behaviors across a large number of social groups exposed to different levels of human disturbance, the scientists found a reduction in behavioral diversity when human impact was high. The results of the study were published this week in the journal Science.
