Fish are particularly sensitive to connectivity loss as their ability to reach spawning grounds is seriously affected. The most common way to circumvent a barrier to longitudinal connectivity, and to mitigate its impacts, is to implement a fish passage device. However, these structures are often non-effective for species with different morphological and ecological characteristics so there is a ...

Previous research indicated that high predictive performance in species distribution modelling can be obtained by combining both biotic and abiotic habitat variables. However, models developed for fish often only address physical habitat characteristics, thus omitting potentially important biotic factors. Therefore, we assessed the impact of biotic variables on fish habitat preferences in four ...

Human pressures on water resources have been suggested as a driver of biological traits that induce changes in native fish populations. This study highlighted the interplay between environmental stress factors, mostly related to flow regulation, and longitudinal river gradient such growth, size structure somatic condition sentinel fish, Luciobarbus sclateri. We found an increase size-related me...

Hydropeaking is widely known for changing the quantity and quality of available habitat downstream hydroelectric facilities, thus affecting all stages fish life cycles. impacts on salmonids are studied, but knowledge its effects cyprinids, which dominant in Mediterranean areas, scarce. In this study, 11 Iberian barbel (Luciobarbus bocagei, Steindachner 1864) were tagged with radio transmitters ...

Amphibians that primarily breed in ephemeral wetlands are especially vulnerable to climate change because they rely on rainfall or temperature to initiate breeding and create suitable hydroregimes (water duration, timing, frequency, depth) for reproductive success. Hydroregime effects on reproductive success are likely to differ among species because of differences in reproductive strategies: t...

A taxonomic review of 23 species of the subgenus Pseudoophonus Motschulsky, 1844, the genus Harpalus Latreille, 1802, occurring in China is given, and a key to these species is provided. The species are divided in three species groups and five subgroups, the distinctive characters of which are listed. The following new synonyms are established: Harpalus calceatus Duftschmid, 1812 = Anisodactylu...
