Phylogenetic community structure: temporal variation in fish assemblage
Hypotheses about phylogenetic relationships among species allow inferences about the mechanisms that affect species coexistence. Nevertheless, most studies assume that phylogenetic patterns identified are stable over time. We used data on monthly samples of fish from a single lake over 10 years to show that the structure in phylogenetic assemblages varies over time and conclusions depend heavil...
متن کاملTemporal and spatial distribution pattern of Bullacta exarata in a tidal flat at south shore of Hangzhou Bay, China
The distribution pattern of Bullacta exarata was studied in different seasons of 2004 at south shore of Hangzhou Bay, China. We found that the distribution pattern of B. exarata was aggregated in each season by Taylor's power regression and Iwao's plot regresses methods (P < 0.001). Based on two-way ANOVA analysis, the results indicated that the densities were significantly affected by the fact...
متن کاملSpatial and Temporal Variation in Fish Assemblage Structure in Village Creek, Hardin County, Texas
-Fish assemblages were sampled seasonally at Village Creek, a blackwater tributary of the Neches River in Hardin County, Texas. Forty-four fish species were captured from aquatic mesohabitats that included backwater pools, deep channel pools, sloping sandbanks, sandy riffles, and shallow channel margins. Associations between fish assemblage structure and mesohabitats were strong, yet also affec...

متن کاملSpatio-temporal variation of fish taxonomic composition in a South-East Asian flood-pulse system
The Tonle Sap Lake (TSL) is a flood-pulse system. It is the largest natural lake in South-East Asia and constitutes one of the largest fisheries over the world, supporting the livelihood of million peoples. Nonetheless, the Mekong River Basin is changing rapidly due to accelerating water infrastructure development (hydropower, irrigation, flood control, and water supply) and climate change, bri...
