"Pour les plantes, l’extinction des espaces capables de disperser des graines est néfaste. En ce sens, ces animaux perdent la capacité à migrer vers des lieux moins inhospitaliers et impactés par le réchauffement climatique. Ce sont les conclusions d’une nouvelle étude publiée jeudi dans la revue Science."

Most plant species depend on animals to disperse their seeds, but this vital function is threatened by the declines in animal populations, limiting the potential for plants to adapt to climate change by shifting their ranges. Using data from more than 400 networks of seed dispersal interactions, Fricke et al. quantified the changes in seed disposal function brought about globally by defaunation. Their analyses indicate that past defaunation has severely reduced long-distance seed dispersal, cutting by more than half the number of seeds dispersed far enough to track climate change.

U.S. wildlife officials proposed greater protections for two rare insects in Glacier National Park on Monday, saying warmer temperatures caused by climate change are drying up the mountain streams where they live. The western glacier stonefly and the meltwater lednian stonefly live primarily in streams fed by cold water from glaciers and snowfields.
