The research seminar was about the Neotropical Floodplain River, a biogeography region of the New World that stretches southward from the Tropic of Cancer and includes southern Mexico, Central and South America, and the West Indies. Specifically, the study site was conduced in the most southern part of Venezuela; the Cinaruco River which contains an enormous variety of fish. Some examples of the fish living in the river are the "electric" fish, sling rays, cat …showed first 75 words of 365 total…

The larger the C-score, the less was the coexistence between species pairs; C-scores are standardized and may be compared among matrices. The dynamic nature of tropical rain rivers habitats of variety complexity, are continuously made available and inhospitable. The nearly continuous assembly and reassembly of local communities are made by species of diverse colonization. Habitat simplification is predictable to result in reduced number of species in local habitats.
