Fish Fauna in Iberian Mediterranean River Basins: Biodiversity, Introduced Species and Damming Impacts
1. We used a basin approximation to analyse distribution patterns of different components of biodiversity (taxonomic richness, endemicity, taxonomic singularity, rarity) and conservation status of freshwater fish fauna in 27 Mediterranean Iberian rivers. 2. Basin area alone explained more than 80% of variation in native species richness. Larger basins featured not only a higher number of native...
متن کاملAssessment of Fish Biodiversity in Oni River, Ogun State, Nigeria
For the purpose of sustainable exploitation of the fishery resources of Oni River, Ogun State, Nigeria, the fish biodiversity assessment was carried out. This was conducted by enumerating and identifying fish species composition, measuring the fish length, fish weight, assessing the fish abundance and biomass, determining the length-weight relationships and the length-frequency of the fishes. A...
متن کاملThe fish fauna of Anambra river basin, Nigeria: species abundance and morphometry.
The fish yields of most Nigeria inland waters are generally on the decline for causes that may range from inadequate management of the fisheries to degradation of the water bodies. Sustainable exploitation requires knowledge of the ichthyofaunal composition in the water bodies. We did a survey of fish species in Anambra river basin for 22 months. Fish samples were collected using four different...
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 کاملIberian fish records in the vertebrate collection of the Museum of Zoology of the University of Navarra
The study of freshwater fish species biodiversity and community composition is essential for understanding river systems, the effects of human activities on rivers, and the changes these animals face. Conducting this type of research requires quantitative information on fish abundance, ideally with long-term series and fish body measurements. This Data Descriptor presents a collection of 12 dat...
