how have european freshwater fish species changed over time?




over time, humans have contributed to the loss of native species and have introduced non-native species throughout europe. a new analysis shows how european freshwater fish have changed profoundly since 1840. at the continental scale, the contemporary fauna holds net 11 more species today as exotic ...

three new sub-species of snow leopard discovered




a recent research paper in the journal of heredity reveals that there are three sub-species of snow leopard. until now, researchers had assumed this species, panthera uncia, was monotypic.



study sheds new light on how species extinction affects complex ecosystems




research by the university of southampton has found that methods used to predict the effect of species extinction on ecosystems could be producing inaccurate results. this is because current thinking assumes that when a species vanishes, its role within an environment is lost too.

reducing pressure on predators, prey simultaneously is best for species' recover




corvallis, ore. - reducing human pressure on exploited predators and prey at the same time is the best way to help their populations recover, a new study indicates.the findings about synchronous recovery are important because historically about half the attempts at species restoration have amounted ...

new species evolve faster as mountains form




plants in the hengduan mountains. credit: jian huang.mountains, like rainforests, are hotbeds of biodiversity. but scientists aren't sure why. for years, they've thought that it might be related to the new environments that arise when mountains form— as plants and animals adapt to the new micro-ha...



new york schools help cornell monitor local waterways for invasive species




invasive aquatic species like round goby, asian carp, and sea lamprey are a growing problem in new york state. their presence impacts water quality, food supply, recreation and tourism, as well as human and animal health. early detection is a critical first step in monitoring a species' spread and m...

ecological value of exotic water plants equals that of indigenous species




when it comes to their role in aquatic ecosystems, exotic water plants are generally no different than indigenous species. in fact, they can be an asset. that doesn't mean all exotic species should be given free rein. but they can be managed more effectively if you focus on their properties and not ...
