Diel changeover in sandbank fish assemblages in a neotropical floodplain river
Fishes were collected over 7 months (February to June and November to December 1999) from seven sandbanks located on the main channel of the Cinaruco River, Venezuela. Significant shifts in assemblage structure and species richness were documented between diurnal and nocturnal samples. Seine samples standardized for effort yielded 41 604 individual fishes representing seven orders, 25 families,...
متن کاملRegionally nested patterns of fish assemblages in floodplain lakes of the Magdalena river (Colombia)
We investigated if fish assemblages in neotropical floodplain lakes (cienagas) exhibit nestedness, and thus offer support to the managers of natural resources of the area for their decision making. The location was floodplain lakes of the middle section of the Magdalena river, Colombia. We applied the nested subset analysis for the series of 30 cienagas (27 connected to the main river and three...
متن کاملRiver Floodplain Connectivity and Lateral Fish Passage: A Literature Review
Floodplains play a key role in the ecology of the Upper Mississippi River; however, humans have significantly affected the ecological function of floodplains by isolating them from the main stem of the river with levees. Impoundment and channel training within the main stem also influence floodplain function by altering the flow of water through the system. Because of the key role hydrology pla...
متن کاملFish assemblages and habitat ecology of River Pinder in central Himalaya, India
Snow-fed River Pinder -a tributary of River Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...
