Freshwater fish functional diversity shows diverse responses to human activities, but consistently declines in the tropics

Ecography, EarlyView.
Freshwater environments are intertwined with human activities and the consequence has been environmental degradation and biodiversity loss. Fish provide key ecological and economic benefits, and fish abundance and diversity can be affected by human activities resulting in functional diversity (FD) changes that might scale up to ecosystem impacts ...

Projected Warming of the Southern Ocean Disrupts Embryonic Development and Hatch Timing in Antarctic Fish

Global Change Biology Communications, EarlyView.
Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.
