Researchers studied the genome of wasp species which attack different aphid species, in order to understand which adaptations allow them to get around their hosts’ defenses.
Smaller organisms are typically more abundant than larger ones, which is a fundamental characteristic of ecological communities. How environmental pulse disturbances affect these « abundance pyramids » remains poorly understood. In a study recently published in Ecology Letters, researchers from iEES Paris and the University of Zürich showed that disturbances which are not size-selective still […]
