To better understand the effects of climate change on the bird community in the Sierra Nevada region, researchers examined the impacts to birds from a recent extreme drought (2013-2016). The drought resulted in the widespread death of pine trees due to attacks by bark beetles, potentially impacting wildlife habitat. While the results were varied, researchers found that many bird species responded positively to the climate conditions associated with the drought, potentially offsetting the negative habitat impacts of the dead trees.
Researchers at the German Centre for Integrative Biodiversity Research (iDiv) and Martin Luther University Halle-Wittenberg (MLU) have succeeded in constructing, from scattered data, a world map of the diversity of tree species. Climate plays a central role for its global distribution; however, the number of species in a specific region also depends on the spatial scale of the observation, the researchers report in Nature Ecology and Evolution. The new approach could help improve conservation.
Simply protecting small forests will not maintain the diversity of the birds they support over the long run, a Rutgers-led study says. Forests need to be carefully monitored and managed to maintain their ecological integrity.
More than half of the carbon sink in the world's forests is in areas where the trees are relatively young -- under 140 years old -- rather than in tropical rainforests, research at the University of Birmingham shows.
While previous studies showed elk often move into areas disturbed by fires or timber harvest to take advantage of new plant growth, that isn't happening in Wyoming's Sierra Madre Mountains, where elk strongly avoid beetle-killed areas in the summer.
At the southern tip of the Himalayas, farmers in the Kangra region of India's Himachal Pradesh graze cattle among rolling hills and forests. The forests, under management by the state or farmer cooperatives, are thriving. But a new University of Illinois study shows, unlike state-managed forests, farmer cooperatives directly benefit both forest health and farmers.
White-tailed deer feeding habits shape the acoustic properties of their forest habitat, potentially affecting the vocal communication of understory-dwelling songbirds and other species, according to a study published Feb. 13, 2019 in the open-access journal PLOS ONE by Timothy J. Boycott from Vassar College, USA, and colleagues.
The experiment was spread over four continents, from the semiarid grasslands and savannas of Australia to lush pastures in Europe and prairies in America.
Texas A&M graduate student aids in the discovery of flying squirrels fluorescing pink in UV light.
Twenty-five years into a 100-year federal strategy to protect older forests in the Pacific Northwest, forest losses to wildfire are up and declines in bird populations have not been reversed, new research shows.
