In einer Science-Publikation werden die Auswirkungen der invasiven Ameise Pheidole megacephala auf ein Ökosystem in Kenia beschrieben
Abstract
Human activity is driving the rapid loss of global biodiversity, through declines in individual species and the wholesale destruction of ecosystems (1). This loss can arise from myriad forms of anthropogenic disturbance that include land conversion, hunting, pollution, resource extraction, and climate change (2). Although it is often straightforward to document the direct effects of disturbance on species and habitats, these impacts can ripple throughout food webs by altering interactions among species. These indirect effects may have far-reaching consequences that are not immediately apparent, but could fundamentally alter ecosystems. On page 433 of this issue, Kamaru et al. (3) describe how one disturbance—the introduction of an invasive species—disrupted an interaction between trees and ants, and traced its consequences through an African savanna landscape.
