As aquatic oxygen levels decrease with the changing climate, marine and lakewater species face a challenging task of adapting to hypoxic environments – or risk perishing. To examine potential for adaptation, researchers investigated two populations of threespine stickleback: one from a lake that naturally experiences seasonal long-term hypoxia and the other one that does not.

Exposure to low oxygen levels as embryos shapes adult zebrafish behavior 
As a result of climate change, low-oxygen or hypoxic areas have spread to many fish habitats over the past few years. A new study attempts to understand the effect of the exposure to hypoxic conditions during embryo development in zebrafish on their behavior later in life. Researchers found that zebrafish that were exposed to […]
