The effects of climate change on the distribution of an invasive fish in Iran: Gambusia holbrooki (Girard, 1859)
Today, invasive species are considered as one of the major threats to biodiversity and ecosystem functions. The suitable habitats of these species are expected to be expanded under the effects of future climate change hence it is likely to threaten the existence of native species. Consequently, identifying the current and potential distribution range of invasive species is essential for managem...
متن کاملPredictors of male insemination success in the mosquitofish (Gambusia holbrooki)
Identifying targets of selection is key to understanding the evolution of sexually selected behavioral and morphological traits. Many animals have coercive mating, yet little is known about whether and how mate choice operates when these are the dominant mating tactic. Here, we use multivariate selection analysis to examine the direction and shape of selection on male insemination success in th...
متن کاملHomogenization dynamics and introduction routes of invasive freshwater fish in the Iberian Peninsula.
Nonnative invasive species are one of the main global threats to biodiversity. The understanding of the traits characterizing successful invaders and invasion-prone ecosystems is increasing, but our predictive ability is still limited. Quantitative information on biotic homogenization and particularly its temporal dynamics is even scarcer. We used freshwater fish distribution data in the Iberia...
متن کاملPerceived Risk of Predation Affects Reproductive Life-History Traits in Gambusia holbrooki, but Not in Heterandria formosa
Key to predicting impacts of predation is understanding the mechanisms through which predators impact prey populations. While consumptive effects are well-known, non-consumptive predator effects (risk effects) are increasingly being recognized as important. Studies of risk effects, however, have focused largely on how trade-offs between food and safety affect fitness. Less documented, and appre...
متن کاملGene Flow and Maintenance of Genetic Diversity in Invasive Mosquitofish (Gambusia holbrooki)
Genetic analyses contribute to studies of biological invasions by mapping the origin and dispersal patterns of invasive species occupying new territories. Using microsatellite loci, we assessed the genetic diversity and spatial population structure of mosquitofish (Gambusia holbrooki) that had invaded Spanish watersheds, along with the American locations close to the suspected potential source ...
