Recent invasions by non-native gobiid fish species that are ongoing in the Western European rivers Rhine and Meuse, will lead to interactions with native benthic fish species. Since both non-native gobiids and native benthic species are bottom dwelling species with a preference for shelter during at least part of their life cycle, it is likely that competition for shelter will occur between the...
this study was carried out to evaluate the chemical compoition of alosa caspia and results compared with clupeonella engrauliformis which is a common fish catch among clupeonella and clupeidae spp in caspian sea . results showed that the amount of fat, protein, ash and dry matter in alosa was higher than clupeonella. the fatty acid composition showed that the epa was very high in alosa that sho...
Predicting the success of a species' colonization into a novel environment is routinely considered to be predicated on niche-space similarity and vacancy, as well as propagule pressure. The role genomic variation plays in colonization success (and the interaction with environment) may be suggested, but has not rigorously been documented. To test an hypothesis that previously observed ecotype-sp...
Diadromous species are particularly vulnerable to climate change because they utilize both marine and freshwater habitat complete their life cycles. Dispersal plays an important role in restraining the distribution of plant animal species, is a key mechanism allow diadromous adapt changes suitability, but it often not included models that explore population trends under scenarios. The objective...
