A new study published in the journal River Research and Applications provides insight into the magnitude of the effect this waterfall has on endangered fishes in the San Juan River. From 2015-2017 more than 1,000 razorback sucker and dozens of Colorado pikeminnow were detected downstream of the waterfall. Some fish moved to this location from up to 600 miles away in the Colorado River.

A comprehensive analysis of Mesosaurus fossils shows that bones from adults share similarities with land-dwelling animals -- suggesting older Mesosaurus were semi-aquatic, whereas the juveniles spent their time in the water. This new research emphasizes the importance of thoroughly analyzing fossilized remains from across all stages of a reptile's life to get a full appreciation of its lifestyle and behavior.

Researchers have long questioned what impact climate change has on the rate at which corals are growing and building reef habitats in the Florida Keys. A new study from the University of North Carolina at Chapel Hill explored this topic, finding both good and bad news. The rate of coral skeletal growth in the Florida Keys has remained relatively stable over time, but the skeletal density of the region's corals is declining, possibly due to ocean acidification.

Scientists have discovered a new family of molecules that work together to precisely remove unwanted DNA during reproduction in single-celled, freshwater organisms called ciliates.

Silver nanoparticles are increasingly being used in consumer products, such as clothing and personal care products, in the medical and pharmaceutical industry, and in the food industry. That is why their presence is expected to increase in the environment where they can exert harmful effects on organisms. The UPV/EHU's 'Cell Biology in Environmental Toxicology' research group has analysed adult zebrafish to find out the effects that in the long term can be caused by these silver particles present in fresh water.

Ingestion of degrading ocean plastics likely poses a substantial risk to the survival of post-hatchling sea turtles because the particles can lead to blockages and nutritional deficiencies, according to new research.

An international team of researchers has outlined a plan for how to measure changes in key traits of animals and plants and provide these data to policymakers to improve natural resource management and keep nations on track to meet global biodiversity and sustainability goals.

A carbon source stemming from daily fish migrations is implicated in the global carbon cycle.

Inspired by the negative results in the recently published largest-scale analysis of the relation between population density and positions in geographic ranges and environmental niches, a team of US and Mexican scientists identified several issues in the methodology used, able to turn the tables in the ongoing debate. Their findings are published in the innovative open access journal Rethinking Ecology.
