Ultrastructural evaluation of the oocytes and spermatozoa of the scleractinian coral Mussismilia harttii.

Global coverage of living coral has declined by half since 1950s. Reef-building species have been severely impacted in this climate crisis scenario, compromising the future of coral reefs. Despite their importance, there is a lack of knowledge regarding the reproductive biology of scleractinian corals.

Simulated climate change and atrazine contamination can synergistically impair zebrafish testicular function.

Elements that interfere with reproductive processes can have profound impacts on population and the equilibrium of ecosystems. Global warming represents the major environmental challenge of the 21st century, as it will affect all forms of life in the coming decades. Another coexisting concern is the persistent pollution by pesticides, particularly the herbicide Atrazine (ATZ), which is responsible for a significant number of contamination incidents in surface waters worldwide.
