Iconic Joshua trees are facing extinction

By UC Riverside 8/8/2019 They outlived mammoths and saber-toothed tigers. But without dramatic action to reduce climate change, new research shows Joshua trees won’t survive much past this century. UC Riverside scientists wanted to verify earlier studies predicting global warming’s deadly effect on the namesake trees that millions flock to see every year in Joshua Tree National Park. They also…

Saving coral: New guidelines to protect and preserve Caribbean coral

By Ohio State University 7/25/2019 A consortium of coral experts today published new guidelines that could help corals in the Caribbean adapt to warmer, more acidic waters caused by climate change. The guidelines are the first of their kind to offer a definitive plan for collecting, raising and replanting corals in an attempt to maximize their chances for survival. The…

Trees suffered in drought-stricken African savanna

By Yale University 7/30/2019 Savannas cover about 40% of the area of the tropics, yet little is known about the effects of drought on their ecosystems.  A new Yale-led study published in the journal Ecology shows that a severe drought between 2014 and 2016 in Kruger National Park in South Africa killed off a large number of trees, a finding that somewhat…

Plants defend against insects by inducing ‘leaky gut syndrome’

By Pennsylvania State University 7/22/2019 UNIVERSITY PARK, Pa. — Plants may induce “leaky gut syndrome” — permeability of the gut lining — in insects as part of a multipronged strategy for protecting themselves from being eaten, according to researchers at Penn State. By improving our understanding of plant defenses, the findings could contribute to the development of new pest control…

Is wildfire management ‘for the birds’?

By UC Berkeley 7/2/2019 Spotted owl populations are in decline all along the West Coast, and as climate change increases the risk of large and destructive wildfires in the region, these iconic animals face the real threat of losing even more of their forest habitat. Rather than attempting to preserve the owl’s remaining habitat exactly as is, wildfire management —…

Parasites hinder reproduction for seabird mothers

By University of Liverpool 7/19/2019 A study by the University of Liverpool and Centre for Ecology & Hydrology (CEH) has found that parasites reduced female seabirds’ reproductive success by 30%, whilst seeming to have little effect on male seabirds. A seven year study of European shags on the Isle of May off the East coast of Scotland sought to explore the impact…

Researcher documents cascading effects of parasites on underwater ecosystems

By Florida State University 6/11/2019 Research by an evolutionary biologist from Florida State University has shown parasites have important and far-reaching effects on predatory fish and the ecosystems they inhabit. These findings, published this week in the journal Ecology, provide important evidence for the little-studied role of parasites in trophic cascades, which are powerful, indirect interactions that can affect entire…

“Extinct” tree re-discovered by ecology student on Indonesian island

By Manchester Metropolitan University 7/4/2019 A rare tree has been re-discovered in a remote area of Indonesia decades after it was thought to be extinct. Liam Trethowan, an ecology PhD student at Manchester Metropolitan University, spotted a cluster of ‘Kalappia’ trees some 200 km from where it was last seen in the 1970s while conducting fieldwork in the Indonesian rain…
