Published Invasive rats transform reef fish behavior
(via sciencedaily.com) Scientists have discovered for the first time that invasive rats on tropical islands are affecting the territorial behavior of fish on surrounding coral reefs. The new study shows that the presence of invasive black rats on tropical islands is causing changes in the territorial behavior of the jewel damselfish -- a herbivorous species of tropical reef fish that 'farm' algae in the branches of corals.
Published Effects of highly pathogenic avian influenza on canids investigated
(via sciencedaily.com) Researchers have revealed the effects of high pathogenicity avian influenza virus infection on an Ezo red fox and a Japanese raccoon dog, linking their infection to a recorded die-off of crows.
Published Current Antarctic conservation efforts are insufficient to avoid biodiversity declines, study shows
(via sciencedaily.com) Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent's plants and wildlife by the year 2100, according to a new study.
Published Bird diversity increased in severely burned forests of Southern Appalachian mountains
(via sciencedaily.com) A new study found bird diversity increased in North Carolina mountain forest areas severely burned by wildfire in 2016, reinforcing that while wildfire can pose risks to safety and property, it can be beneficial to wildlife. The study results could help forest managers better predict bird responses to wildfire, and manage forests to benefit birds.
Published Palau's Rock Islands harbor heat-resistant corals
(via sciencedaily.com) Original source Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot. In the last 4 decades, marine heatwaves have caused widespread bleaching, and killed millions of corals. Because of this, a global search is underway for reefs that can withstand the heat stress, survive future warming, and act as sources of heat-tolerant coral larvae to replenish affected areas both naturally and through restoration.
Published Ecology: More than the sum of its parts
(via sciencedaily.com) Original source The number of simultaneously acting global change factors has a negative impact on the diversity of plant communities -- regardless of the nature of the factors.
