Native and Non-Native Supergeneralist Bee Species Have Different Effects on Plant-Bee Networks

open access: yesPLOS ONE, 2015
Los supergeneralistas, definidos como especies que interactúan con múltiples grupos de especies en redes ecológicas, pueden actuar como conectores importantes de subconjuntos de especies que de otro modo estarían desconectados. En Brasil, hay dos abejas supergeneralistas: la abeja Apis mellifera, una especie no nativa, y Trigona spinipes, una abeja ...
