The threat posed by invasive non-native species worldwide requires a global approach to identify which introduced are likely pose an elevated risk of impact native and ecosystems. To inform policy, stakeholders management decisions on threats aquatic ecosystems, 195 assessors representing 120 assessment areas across all six inhabited continents screened 819 from 15 groups organisms (freshwater, brackish, marine plants animals) using the Aquatic Species Invasiveness Screening Kit. This...
Abstract Anthropogenic stream impoundments often result in altered flow regimes and reservoir formations. Functional fish characteristics may change response to conditions, understanding the underlying mechanisms at work (e.g. natural selection phenotypic plasticity) is of great importance both evolutionary conservation contexts. Cyprinella lutrensis a widely distributed minnow native systems Missouri, U.S.A. Following impoundment Osage River, C. currently occurs resultant Truman Reservoir...
The relationships of Guiana Shield members Trichomycterus are examined using three mitochondrial genes (Cytochrome Oxidase 1, Cytochrome b, and 16s) one nuclear gene (RAG 2). A time-calibrated phylogeny is implemented to examine how diversification related the timing major geographical events in Shield. There was topological discordance among trees; however, they overall suggest presence two subclades. T. guianensis subclade consists strongly supported sp. 'Potaro, elongate' (Potaro R.)...
The Gymnotiformes, or electric knifefishes, is a clade of freshwater ostariophysan fishes native to tropical South and Central America that are easily recognized by the presence an elongate body undulating anal fin, lack dorsal pelvic fins. In this study, we report on unusual specimens Black Ghost Knifefish Apteronotus albifrons (Apteronotidae) exported from Asian aquaculture facilities, which exhibit fin located median surface. This exhibits distinctive ball-and-socket articulating joint...
