Human Activity, not Ecosystem Characters, Drives Potential Species Invasions
0196 From the Asian tiger mosquito in the American South, to the Eurasian zebra mussel in the Great Lakes, to European quackgrass throughout the United States, invasions of non-native species can disrupt ecosystems, cause havoc with local economies, and even threaten health. A new study shows that, at least for freshwater fishes, the major driver of successful invasion is human development, not...
متن کاملAbundance of common species, not species richness, drives delivery of a real-world ecosystem service.
Biodiversity-ecosystem functioning experiments have established that species richness and composition are both important determinants of ecosystem function in an experimental context. Determining whether this result holds for real-world ecosystem services has remained elusive, however, largely due to the lack of analytical methods appropriate for large-scale, associational data. Here, we use a ...
متن کاملSimulating Invasions in a Spatially Structured Ecosystem
A recent distribution modell1] suggests that the success of ecological invasions diminish with the number of species in the resident community. However , such models generally lack any spatial structure or representation of the resources in the environment. The continuous distribution model of Casee1] was transformed into a connguration model that included a parameter for the dimensions of a sp...
متن کاملEvolutionary speed of species invasions.
Successful invasion may depend of the capacity of a species to adjust genetically to a spatially varying environment. This research modeled a species invasion by examining the interaction between a quantitative genetic trait and population density. It assumed: (I) a quantitative genetic trait describes the adaptation of an individual to its local ecological conditions; (2) populations far from ...
متن کاملThe Human Release Hypothesis for biological invasions: human activity as a determinant of the abundance of invasive plant species
Research on biological invasions has increased rapidly over the past 30 years, generating numerous explanations of how species become invasive. While the mechanisms of invasive species establishment are well studied, the mechanisms driving abundance patterns (i.e. patterns of population density and population size) remain poorly understood. It is assumed that invasive species typically have hig...
