Page 13: Research news on endangered species

An endangered species is a taxonomic group (typically at the species level) that faces a very high risk of extinction in the near future across all or a significant portion of its range, as determined by quantitative assessment criteria such as population size, rate of decline, geographic range, and degree of habitat fragmentation. In conservation biology and environmental policy, endangered status guides prioritization of management actions, legal protections, and resource allocation. Scientific evaluation commonly uses standardized frameworks (e.g., formal Red List–type criteria) based on demographic trends, reproductive rates, and known or projected threats, including habitat loss, overexploitation, invasive species, pollution, and climate change.

Bottom trawling is scraping oceans of wildlife

Bottom trawlers extract one-quarter of the world's fisheries catches by weight and raise significant ecological, economic and social concerns. Given that, you'd think there would be an answer to basic questions in fisheries: ...

Beluga calls deciphered to bolster conservation efforts

Alaska's Cook Inlet was home to nearly 1,300 beluga whales in the late 1970s, but today the population hovers around 300. Despite almost two decades of recovery work, the whales aren't bouncing back. The Cook Inlet belugas ...

Complex habitat crucial to brush-tailed rock-wallaby survival

Brush-tailed rock-wallaby populations have dwindled for more than a century due to historical hunting for the European fur trade and competition and predation from introduced species. New research shows terrain complexity ...
