TL;DR: Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation, and current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups.

TL;DR: To achieve true sustainability, assessments of new projects must go beyond local impacts by accounting for synergies with existing dams, as well as land cover changes and likely climatic shifts, and call for more sophisticated and holistic hydropower planning.

TL;DR: In this article, the authors evaluated how congruent three commonly used metrics of diversity were among taxa for six groups of freshwater species and found that broad-scale patterns of species richness, threatened-species richness and endemism lack congruence among these metrics.

TL;DR: A comprehensive IUCN Red List assessment of the freshwater crabs, which was the first time that such a study had been attempted on a global scale for any group of freshwater invertebrates, shows that the proportion of freshwater crabs threatened with extinction is equal to that of reef-building corals, and exceeds that of all other groups assessed except for amphibians.

TL;DR: The first global assessment of an insect order (Odonata) provides new context to the ongoing discussion of current biodiversity loss and finds that one in 10 species of dragonflies and damselflies is threatened with extinction.
