More Harm than Good: When Invader Vulnerability to Predators Enhances Impact on Native Species
Invasion biologists typically regard susceptibility of an invasive species to native predators as a fortuitous condition that increases biotic resistance to the invasion. The line of reasoning is that predation weakens the net impact of the invader and reduces its ability to displace native competitors. However, predation on invasives is a coupled interaction; every invader consumed also enhanc...
متن کاملEffects of native species diversity and resource additions on invader impact.
Theory and empirical work have demonstrated that diverse communities can inhibit invasion. Yet, it is unclear how diversity influences invader impact, how impact varies among exotics, and what the relative importance of diversity is versus extrinsic factors that themselves can influence invasion. To address these issues, we established plant assemblages that varied in native species and functio...
متن کاملAnalysis of the Jobs Resource Utilization on a Production System
In HPC community the System Utilization metric enables to determine if the resources of the cluster are efficiently used by the batch scheduler. This metric considers that all the allocated resources (memory, disk, processors, etc) are full-time utilized. To optimize the system performance, we have to consider the effective physical consumption by jobs regarding the resource allocations. This i...
متن کاملDe novo transcriptome sequencing of a non-model polychaete species.
Transcriptome sequencing is a useful method for studying gene-sequences data, especially in non-model organisms whose genomic sequences are yet to be determined. Indeed, even without any genome reference, transcripts can be assembled de novo to produce a genome-scale transcription map. Here we describe a de novo transcriptome assembly for the polychaete worm Ophryotrocha diadema, generated from...
متن کاملGrassland invader responses to realistic changes in native species richness.
The importance of species richness for repelling exotic plant invasions varies from ecosystem to ecosystem. Thus, in order to prioritize conservation objectives, it is critical to identify those ecosystems where decreasing richness will most greatly magnify invasion risks. Our goal was to determine if invasion risks greatly increase in response to common reductions in grassland species richness...
