Impacts of invasive alien marine species on ecosystem services and biodiversity:a pan-European review
A good understanding of the mechanisms and magnitude of the impact of invasive alien species on ecosystem services and biodiversity is a prerequisite for the efficient prioritisation of actions to prevent new invasions or for developing mitigation measures. In this review, we identified alien marine species that have a high impact on ecosystem services and biodiversity in European seas, classif...
متن کاملThe 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 کاملImportance of genetic diversity in eelgrass Zostera marina for its resilience to global warming
Effects of global warming on marine ecosystems are far less understood than they are in terrestrial environments. Macrophyte-based coastal ecosystems are particularly vulnerable to global warming, because they often lack species redundancy. We tested whether summer heat waves have negative effects on an ecologically important ecosystem engineer, the eelgrass Zostera marina L., and whether high ...
متن کاملEngineering or food? mechanisms of facilitation by a habitat- forming invasive seaweed
Nonnative species that form novel habitats strongly affect ecosystem processes. The effects of these ecosystem engineers can be both positive and negative but the mechanisms behind their effects are not well described. In this study we determined the relative importance of three main mechanisms by which invasive ecosystem engineers can facilitate native fauna. The engineer may provide new physi...
متن کاملEvaluation of the Impact of Actors on Ecosystem Accounting
This study aimed to evaluate the effect of type of players on ecosystem accounting system using structural equations. In total, 84 activists in the field of environmental accounting (ecosystem) were selected through convenience sampling. Subjects filled the 22-item questionnaire of components of actor network and the 25-item questionnaire of ecosystem accounting. Given the fact that the signifi...
