New international research reveals the far-reaching impacts of forest cover loss on global biodiversity. The study, led by the University of Edinburgh and the University of St Andrews, investigated the impacts of forest loss on species and biodiversity over time and around the world, revealing both losses and gains in species.
Focusing on biodiversity data spanning(跨越) 150 years and over 6,000 locations, the study, published in Science, reveals that as tree cover is lost, plants and animals are responding to the transformation of their natural habitats.
Bringing together over 5 million records of the numbers of different plants and animals with information on both historic and contemporary peaks in forest loss, the researchers discovered both immediate and delayed effects of forest loss on ecosystems.
The pace at which biodiversity responds to forest loss varies from a few years, as is the case for light-loving plants and insects, to decades for long-living trees and larger birds and mammals. Gergana Daskalova, a Ph.D. student in the School of GeoSciences at the University of Edinburgh and lead author of the study, said, "Changes in the biodiversity of the planet's forests matter because they will reflect how these landscapes look, the types of species they support and the benefits that forests provide for society like clean air and water.”
Maria Dornelas, a co-senior author from the School of Biology at the University of St Andrews, continued, "Humans are undoubtedly changing the planet. Yet, global analyses of how biodiversity is changing over time are revealing biodiversity changes are nuanced(有细微差别的) and variable.”
She added, "With a better understanding of the different ways, both positive and negative, in which forest loss influences biodiversity, we can improve future conservation and restoration of global ecosystems.”
