Global imprint of historical connectivity on freshwater fish biodiversity.
The relative importance of contemporary and historical processes is central for understanding biodiversity patterns. While several studies show that past conditions can partly explain the current biodiversity patterns, the role of history remains elusive. We reconstructed palaeo-drainage basins under lower sea level conditions (Last Glacial Maximum) to test whether the historical connectivity b...
متن کاملPredicting spatial similarity of freshwater fish biodiversity.
A major issue in modern ecology is to understand how ecological complexity at broad scales is regulated by mechanisms operating at the organismic level. What specific underlying processes are essential for a macroecological pattern to emerge? Here, we analyze the analytical predictions of a general model suitable for describing the spatial biodiversity similarity in river ecosystems, and benchm...
متن کاملBiodiversity of freshwater fish of a protected river in India: comparison with unprotected habitat.
In India, freshwater environments are experiencing serious threats to biodiversity, and there is an urgent priority for the search of alternative techniques to promote fish biodiversity conservation and management. With this aim, the present study was undertaken to assess the fish biodiversity within and outside a river protected area, and to evaluate whether the protected river area provides s...
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 کاملBiodiversity and Biogeography
As we have seen, life has been important in shaping its own environment throughout its 3.8 Ga* geologically recorded history. It has influenced earth-surface temperatures (Classes 2, 9, 10) through its involvement in the geochemical cycles that determine the world oceans salt content and the atmospheres composition (Classes 7-10). Overall, lifes effects have tended to compensate for the ther...
