Evaluating detectability of freshwater fish assemblages in tropical streams: Is hand-seining sufficient?

Unprecedented threats to natural ecosystems mean that accurate quantification of biodiversity is a priority, particularly in the tropics which are underrepresented in monitoring schemes. Data from a freshwater fish assemblage in Trinidad were used to evaluate the effectiveness of hand-seining as a survey method in tropical streams. We uncovered large differences in species ...

Immediate impact of the tsunami associated with the 2011 Great East Japan Earthquake on the Plecoglossus altivelis altivelis population from the Sanriku coast of northern Japan

The huge tsunami associated with the 2011 Great East Japan Earthquake severely impacted the ecosystems on the Sanriku coast of Japan. The life history traits of ayu, Plecoglossus altivelis altivelis, which have a one-year amphidromous life history, were investigated by otolith analyses in two rivers of the Sanriku coast just after the tsunami compared with results before the ...

The effect of dams on the larval abundance and composition of four carp species in key river systems in China

The four species of carp present in China (grass carp, black carp, silver carp and bighead carp) are all commercially important freshwater fish species. However, the construction of large-scale hydraulic projects, such as dams, along with other anthropogenic changes to river systems has resulted in the rapid decline in abundance of all four carp species. Indeed, the effect of dams ...

Plastic life-history variation along the course of a steep mountainous river in male Cottus hangiongensis (Pisces: Cottidae)

To elucidate the causes of clinal life-history variation in male freshwater amphidromous Cottus hangiongensis found along the river courses, we examined the genetic composition of upstream, midstream, and downstream groups using microsatellite DNA markers and different growth patterns among juvenile individuals before and after they ascended a small, steep mountainous river in ...
