A network of fish ponds supported a permanent human settlement in the seasonal drylands of Bolivia more than one thousand years ago, according to a new study published May 15, 2019 in the open-access journal PLOS ONE by Gabriela Prestes-Carneiro of Federal University of Western Para, Brazil, and colleagues.
Infrastructure development and other man-made changes have already fragmented or disrupted two-thirds of Earth's longest rivers. Dams and reservoirs are the leading contributors to connectivity loss in global rivers. A team of 34 international researchers from World Wildlife Fund (WWF), McGill and other institutions assessed the connectivity status of 12 million kilometers of rivers worldwide, providing the first-ever global assessment of the location and extent of the planet's remaining free-flowing rivers.
The Sea Lab's Discovery Hall Programs Outreach Coordinator Rachel McDonald's work conducting outreach on ACER's research is featured in a special issue of the Gulf of Mexico Research Initiative's (GoMRI) Current: The Journal of Marine Education.
An international team led by IGB is providing one of the first proofs of the complex learning behavior of fish in a recent study. The Atlantic sturgeon is considered extinct in Germany. The IGB is coordinating their reintroduction and is investigating whether sturgeon training can increase their fitness for the wild. An important fitness factor is their feeding behavior. Already a two-week 'learning lead' made the search for food more efficient.
Lifelong chemical records stored in the canine teeth of an elusive group of seals show that the seals remain in freshwater their entire lives and are likely a distinct population from their relatives in the ocean. Their home territory, Iliamna Lake, is in the heart of the proposed Pebble Mine project.
In the wild and in the lab, researchers find a relationship between higher water temperature and a lower percentage of female flounder, a cause for concern.
For the first time, researchers at King's College London, in collaboration with the University of Suffolk, have found a diverse array of chemicals, including illicit drugs and pesticides in UK river wildlife. The study published today in Environment International, looked at the exposure of wildlife, such as the freshwater shrimp Gammarus pulex, to different micropollutants (chemicals found at exceptionally low levels) and the levels of these compounds in the animals.
What makes the red lionfish (Pterois volitans) such a successful and powerful invader in Atlantic Ocean waters compared to its rather lamb-like existence in its native Pacific Ocean? A new NC State study sorts it out.
The taxonomic and trophic composition of freshwater fishes in the Ohio River Basin has changed significantly in recent decades, possibly due to environmental modifications related to land use and hydrology, according to a study published April 24 in the open-access journal PLOS ONE by Mark Pyron of Ball State University, and colleagues.
Global warming has caused twice as many ocean-dwelling species as land-dwelling species to disappear from their habitats, a unique Rutgers-led study found. The greater vulnerability of sea creatures may significantly impact human communities that rely on fish and shellfish for food and economic activity, according to the study published in the journal Nature.
