Fish Species Diversity

The influence of spatial, temporal and environmental factors on fish species diversity in headwater streams in Paraguay and Paraná basins, Brazil was examined. A total of 4,605 individuals were sampled, distributed in 60 species. The sampled streams in Paraná basin presented a larger total species richness (42) than Paraguay streams (40). However the estimated richness was larger in Paraguay basin (53) than Paraná streams (50). The streams of Paraná basin had a greater mean species richness and evenness, while more individuals per sample were found in the Paraguay basin. Difference between the sub-basins were found in the Paraguay basin, while for the basin of Paraná, richness and evenness vary significantly between the sub-basins, but the number of individuals varied seasonally. The most important environmental factors to species diversity and abundance were altitude, water temperature, stream width and stream depth for both the basins.

Fish Species Diversity

Stream and lake fishes are important economic and recreational resources that respond to alterations in their surrounding watersheds and serve as indicators of ecological stressors on aquatic ecosystems. Research suggests that fish species diversity is largely influenced by surface water connectivity, or the lack thereof; however, few studies consider freshwater connections and their effect on both lake and stream fish communities across broad spatial extents. We used fish data from 559 lakes and 854 streams from the midwestern/northeastern United States to examine the role of surface water connectivity on fish species richness and community composition. We found that although lakes and streams share many species, connectivity had a positive effect on species richness across lakes and streams and helped explain species composition. Taking an integrated approach that includes both lake and stream fish communities and connectivity among freshwaters helps inform scientific understanding of what drives variation in fish species diversity at broad spatial scales and can help managers who are faced with planning for state, regional, or national scale monitoring and restoration.

Fish Species Diversity

Abstract Transposable elements (TEs) are genomic sequences that can move, multiply, and often form sizable fractions of vertebrate genomes. Fish belong to a unique group of vertebrates, since their karyotypes and genome sizes are more diverse and complex, with probably higher diversity and evolution specificity of TE. To investigate the characteristics of fish TEs, we compared the mobilomes of 39 species, and observed significant variation of TE content in fish (from 5% in pufferfish to 56% in zebrafish), along with a positive correlation between fish genome size and TE content. In different classification hierarchies, retrotransposons (class), long terminal repeat (order), as well as Helitron, Maverick, Kolobok, CMC, DIRS, P, I, L1, L2, and 5S (superfamily) were all positively correlated with fish genome size. Consistent with previous studies, our data suggested fish genomes to not always be dominated by DNA transposons; long interspersed nuclear elements are also prominent in many species. This study suggests CR1 distribution in fish genomes to be obviously regular, and provides new clues concerning important events in vertebrate evolution. Altogether, our results highlight the importance of TEs in the structure and evolution of fish genomes and suggest fish species diversity to parallel transposon content diversification.
