According to the niche variation hypothesis (NVH), populations with wider niches are phenotypically more variable than those narrow niches. Giller expanded NVH, suggesting that width, morphological variation, and genetic diversity all positively correlated. However, has been a subject of debate discussion. In present study, NVH was tested by analyzing relationships among trophic Hemiculter leuc...

In this study, we aimed to characterize the fish community structure and identify the drivers contributing to homogenization/differentiation processes in four tributaries to the Pearl River, Guangxi Province, China, over the past few decades. We sampled 22 sites seasonally from 2013 through 2015, and these sites were selected based on archived records of previous sampling conducted in the 1980s...

Fish assemblages inhabiting the Taizi River basin have been severely degraded by anthropogenic disturbances, which weaken basin’s ecological function and limited revitalization of northeast industrial base. Long-term rehabilitation has conducted to restore fish fauna improve habitat conditions. To explore distribution patterns key factors after this rehabilitation, a comprehensive detailed surv...

The Sun Moon lake in Central Taiwan is a known endemic area for clonorchiasis. Of the 45 fresh water fish, Hemiculter leucisculus, from the lake that were examined by artificial gastric juice digestion in October 1995, all were found to harbor metacercariae in their muscle. The number of metacercariae isolated from each fish ranged from 2 to 2,185, with an average of 254. A total of 11,443 meta...

The introduction of non-native fish species is known to have adverse effects on aquatic ecosystems, but their effect plateau lakes not well studied. In this study, we examined the Japanese smelt (Hypomesus nipponensis) invasion assemblage in Lake Erhai, a subtropical lake southwestern China. Through cluster analysis and non-metric multidimensional scaling (NMDS), found significant shift: popula...
