Has a river dam affected the life‐history traits of a freshwater prawn? [PDF]

Ecology and Evolution, 2020
In recent years, species richness and diversity in aquatic ecosystems has declined as environments are increasingly impacted by anthropic actions. Freshwater prawns are well adapted to survive in a disturbed and heterogeneous environment.

Global consequences of dam-induced river fragmentation on diadromous migrants: a systematic review and meta-analysis. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The global proliferation of dams has altered flow and sediment regimes in rivers, presenting a major threat to freshwater biodiversity. Diadromous species, such as fishes, decapod crustaceans and gastropods, are particularly susceptible to fragmentation because dams obstruct their breeding migrations between coastal waters and rivers. Although
