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 —…

How to restore a coral reef

By Pennsylvania State University 7/18/2019 New guidelines drafted by a consortium of concerned experts could enable corals to adapt to changing environments and help restore declining coral populations in the Caribbean. The guidelines provide a definitive plan for collecting, raising, and replanting corals that maximizes their potential for adaptation.  A new paper outlining the guidelines, authored by the restoration genetics…

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…

A legal framework for vector-borne diseases and land use

ESA 2019 Preview: Human-induced land use change is the primary driver of EIDs, including those carried by mosquitoes such as malaria, dengue, Zika, EEE, and West Nile. Why, then, does land-use planning often fail to recognize the effects these changes have on the risk of spreading disease?

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…
