Abstract Background To increase ecosystem resilience and biodiversity, the maintenance and improvement of structural and compositional diversity of forests has become an important goal in forest management for many forest owners and jurisdictions. At the same time, future harvesting intensity (HI) may increase to meet the demand for ...
As oil palm plantations expand across the world, razing swaths of tropical rainforests in their path, fears about their impact on the environment have also grown. In the plantations of Colombia, a new study has found yet another way they are altering global biodiversity: by impacting the diversity of mammals. “Some species do very well” […]...
Fire is a keystone process that drives patterns of biodiversity globally. In frequently burned fire-dependent ecosystems, surface fire regimes allow for the coexistence of high plant diversity at fine scales even where soils are uniform. The mechanisms on how fire impacts groundcover community dynamics are, however, poorly understood. Because fire can act as a stochastic agent of mortality, we hyp...
When it comes to the impact of climate change on ecosystems, we still have large knowledge gaps. Most experiments are unrealistic because they do not correspond to projected climate scenarios for a specific region. As a result, we lack reliable data on what ecosystems might look like in the future, as a team of biodiversity researchers from Central Germany show in the journal "Global Change Biolog...
This project focuses on biodiversity: the variety of all life on our planet. It highlights the crisis represented by huge losses of animal, insect, bird and plant life around the world, as well as innovations to tackle these losses....

CHANGCHUN, Sept. 15 (Xinhua) -- UNESCO's 2019 Man and the Biosphere (MAB) Youth Forum kicked off on Sunday in the Changbaishan Biosphere Reserve, northeast China. About 270 young people from 90 countries participated in the forum themed "Committed to Biodiversity"....
A lack of optimal gene combinations, as well as low levels of genetic diversity, is often associated with the formation of species range margins. Conservation efforts rely on predictive modelling using abiotic variables and assessments of genetic diversity to determine target species and populations for controlled breeding, germplasm conservation and assisted migration. Biotic factors such as inte...
New research finds that, for a given rise in global food production, the negative impact on biodiversity of cropland expansion is many times greater than of cropland intensification....

SettyAbstractAssessing the effects of harvesting on the population dynamics of important non-timber forest products (NTFPs) species is important for informing species conservation options, guiding sustainable harvesting practices and offtake and supp...
NEW DELHI: Ministers and representatives from nearly 200 countries have pledged to focus on land-based solutions that will contribute to preventing catastrophic climate change and the conservation of biodiversity. The pledge, the New Delhi Declaration, hammered out over the two-day long high level segment of the 14th general assembly of the United Nations Convention to Combat Desertification, has ...
Life on Earth is amazingly diverse, and exhibits striking geographical global patterns in biodiversity. A pair of companion papers published September 13th in Science reveal that mountain regions-especially those in the tropics-are hotspots of extraordinary and baffling richness. Although mountain regions cover only 25% of Earth's land area, they are home to more than 85% of the world's species of...
