The ability of the Osun River to support biodiversity is being threatened by pollution and can only be rescued if the contamination ends.
Just about every creature on Earth needs to grab some Zs from time to time. Imagine trying to doze while dodging great whites and killer whales.
The photographs show how climate change is disrupting our marine ecosystems – sometimes in ways previously unknown to marine scientists.
UV absorbents and industrial antioxidants are used in many household goods to protect them from UV radiation. They can have an adverse impact on ecosystems.
While official data is yet to be released, this year’s Mediterranean marine heatwave will likely have devastating ecological consequences.
The true cost of marine conservation often falls on vulnerable coastal communities. Can a ‘beneficiary pays’ approach protect both endangered species and the communities dependent on them?
Wetlands can help limit the spread of the voracious round goby, an invasive species that has infiltrated the Great Lakes and has become widespread in the St. Lawrence River.
Federal Labor has pledged to deliver the Murray Darling Basin Plan. But a new report casts serious doubt on that promise.
Migratory fish populations have collapsed worldwide in the last 50 years.
The first hammerhead shark was likely the result of a genetic deformity. A biologist explains how shark DNA reveals hammerheads’ history.
The newly discovered species – Qikiqtania – highlights evolution’s twisty, tangled path.
There is a need for nuanced discussions around the role of fisheries subsidies — even those that may be nominally harmful — to avoid further inequity and marginalization of small-scale fishers.
A biologist explains how researchers nail down the age of ancient fossils thanks to a physical process called radioactive decay.
There is a need for better innovations and policies to help improve the fisheries sector in this region.
We need to advance our understanding of the effects of microplastics on aquatic ecosystems, especially on small animals at the base of food webs that might be ingesting more of these particles.
Puerto Rico’s tourism industry is booming as nations lift COVID-19 travel restrictions, but development is displacing people who have lived along its coastlines for years.
Creating opportunities to meaningfully engage women in governance and decision-making is necessary to achieve gender equality in small-scale fisheries.
When humans eat fish, mussels and other foods containing antibiotics, the residual antibiotics may cause bacterial pathogens to become resistant.
