Biodiversité

Déjà exploitées par des archéologues, des photographies prises par des satellites espions pendant la guerre froide (puis déclassifiées) devraient aussi servir à analyser la dégradation des milieux naturels, prône une étude dirigée par des scientifiques de l'université de Fribourg en Allemagne (BioScience).

As both a flagship and umbrella species, the giant panda (Ailuropoda melanoleuca) is one of the most heavily invested species in conservation. Here, we report the wide distribution range retreat of the leopard (Panthera pardus, 81% loss), snow leopard (P. uncia, 38%), wolf (Canis lupus, 77%) and dhole (Cuon alpinus, 95%) from protected areas in the giant panda distribution range since the 1960s. The present findings indicate the insufficiency of giant panda conservation for protecting these large carnivore species and suggest that future conservation efforts should target restoring ecosystems with high trophic complexity to facilitate the recovery of large carnivore populations. Comparing historical records with contemporary camera trap surveys, the authors report widespread declines in the occurrence of four large carnivore species from protected areas within the distributional range of the giant panda.
