Do ecological flows benefit exotic species ?
Rivers are among the ecosystems that have been most damaged by human pressure, especially in European countries where most streams are regulated. An important instrument to mitigate such impacts is to provide adequate ecological flows, which allows for the preservation of fish populations. Nowadays, many rivers are invaded by exotic species that, being more opportunistic and tolerant, are chang...
متن کاملEcological determinants of parasite acquisition by exotic fish species
Disease-mediated threats posed by exotic species to native counterparts are not limited to introduced parasites alone, since exotic hosts frequently acquire native parasites with possible consequences for infection patterns in native hosts. Several biological and geographical factors are thought to explain both the richness of parasites in native hosts, and the invasion success of free-living e...
متن کاملDeriving Field-Based Ecological Risks for Bird Species
Ecological risks (ERs) of pollutants are typically assessed using species sensitivity distributions (SSDs), based on effect concentrations obtained from bioassays with unknown representativeness for field conditions. Alternatively, monitoring data relating breeding success in bird populations to egg concentrations may be used. In this study, we developed a procedure to derive SSDs for birds bas...
متن کاملRestoring Balance: Using Exotic Species to Control Invasive Exotic Species
Invasive species threaten natural habitats worldwide, and active human management is required to prevent invasion, contain spread, or remediate ecosystems following habitat degradation. One powerful technology for invasive species management in sensitive habitats is biological control, the use of carefully selected upper-trophic-level organisms that utilize the exotic pest as a resource, thereb...
متن کاملLearning from Exotic Species
Research of unique features in exotic animal species often reveals unexpected biology and may even shed light on disease treatment. A recent paper by Tian et al. studies a long-lived, cancer-free rodent named the naked mole rat (Heterocephalus glaber) to understand the mechanism of cancer resistance. Previous work by the same group has suggested early contact inhibition (ECI) in the naked mole ...
