Potential problems of removing one invasive species at a time: Interactions between invasive vertebrates and unexpected effects of removal programs

摘要: Although the co-occurrence of nonnative vertebrates is a ubiquitous global phenomenon, study interactions between invaders poorly represented in literature. Limited understanding co-occurring can be problematic for predicting how removal only one invasive—a common management scenario—will affect native communities. We suggest trophic food web framework effects single-species on biodiversity. used literature search and meta-analysis to assess current invasive vertebrate affects biodiversity relative when two invasives are present. The majority studies focused carnivores, mainly within aquatic systems, which highlights critical knowledge gap our vertebrates. found that caused significant negative effect species compared were These unexpected results could arise because positioning hierarchy (e.g. carnivore-carnivore or carnivore-herbivore). consider there important gaps determinate multiple co-existing ecosystems, this information precious management.
