Proposals being accepted for ecology research funding

The Ecology Institute announced a call for proposals for its Flower Grant program. The funds aim to support ecology research focused across the institute’s five core themes: resilience and adaptation; provision of ecosystem goods and services; ecology at the interface; rapid evolutionary change; and ecological foundations.

South African forests show pathways to a sustainable future

Native forests make up one percent of the landscape in South Africa but could play a key role in reducing atmospheric carbon and identifying sustainable development practices that can be used globally to counter climate change, according to a Penn State researcher.
