Invasiones biológicas y pérdida de polinizadores

Montero-Castano, A., Calvino-Cancela, M., Rojas-Nossa, S., De la Rua, P., Arbetman, M., Morales, C.L. 2018. Biological invasions and pollinator decline. Ecosistemas 27(2): 42-51. Doi.: 10.7818/ECOS.1319 Biological invasions are among the main threats to biodiversity, and pollinators are not exempt from such threat.Here, we review the mechanisms through which animal and plant invasive species may affect pollinators, either directly or indirectly. We classified these mechanisms in four groups: (a) changes in habitat quantity or quality, (b) predation, (c) pathogen spread and (d) genetic introgression. We review the impacts of these mechanisms on the behaviour, demography and evolution of native pollinators and their communities. In addition, we highlight some current knowledge gaps about the effect of biological invasions on pollinators and suggest some measures to minimize such effects.
