Des chercheurs australiens estiment que ressusciter des espèces disparues pourrait conduire à la réduction des moyens destinés à la conservation de celles encore en vie.

Carbon emissions to the atmosphere from streams and rivers are expected to increase as warmer water temperatures stimulate faster rates of organic matter breakdown. But a new study led by University of Utah researcher Jennifer J. Follstad Shah, in collaboration with a team of 15 scientists in the U.S. and Europe, suggests these decay rates may not increase as much as expected.

Giant pandas’ patches are among the most striking of any mammal : black ears and eye spots set against a white face, with dark limbs and shoulders abutting a white neck and torso. Scientists have proposed dozens of reasons for the animals’ piebald appearance.

Tracking changes in ecosystems is both vital and extremely difficult. We need to know how differences in climate and land use will affect the success of different species, and what impacts this will have on the wider environment. Plant-pollinator interactions are particularly important for the stability of ecological communities, but how will these relationships be affected in the future and what will happen to the ecosystem services they provide ?

Une étude, publiée dans « PloS One », fait du pachyderme le plus petit dormeur du monde animal, avec deux heures de sommeil par nuit.
