ecological principles for managing land use
... The full ecological effects of human activities often are not seen for many years. The imprint of a land use may persist on the landscape for a long time, constraining future land use for decades or centuries even after it ceases. Long-term effects of land use or management may be difficult to predi ...

Waterfalls drive parallel evolution in a freshwater goby
... Waterfalls may affect fish distribution and genetic structure within drainage networks even to the extent of leading evolutionary events. Here, parallel evolution was studied by focusing on waterfall and the landlocked freshwater goby Rhinogobius sp. YB (YB), which evolved from amphidromous R. brunn ...

As the reproductive biology of most target species has not been studied, and as the capture of rarer alleles would require a markedly increased sample size, collectors are advised to sample from in excess of 50 individuals, from within a single population, where available. This analysis suggests tha ...
