Angling fish for food: Study finds recreational fishing accounts for 11% of reported harvest in inland fisheries
Rod and reel fishing is much more than a recreational activity: It makes an important contribution to the diet in many regions of the world. This is shown by an international team of researchers, including Robert Arlinghaus, Professor for Integrative.....»»
Unearthing the impacts of hydrological sensitivity on global rainfall
Georgia Tech researcher Jie He set out to predict how rainfall will change as Earth's atmosphere continues to heat up. In the process, he made some unexpected discoveries that might explain how greenhouse gas emissions will impact tropical oceans, af.....»»
Scientists find ancient, endangered lamprey fish in Queensland, 1400 km north of its previous known range
The Australian brook lamprey (Mordacia praecox) is part of a group of primitive jawless fish. It's up to 15 cm long, with rows of sharp teeth. Surprisingly, it doesn't use these teeth to suck blood like most lamprey species—it's non-parasitic......»»
Genetic study finds early summer fishing can have an evolutionary impact, resulting in smaller salmon
Atlantic salmon are caught by fisheries when the fish are migrating to spawn. A new study led by the University of Helsinki explored how salmon caught at different times during their spawning migration differ from each other genetically. The study on.....»»
Researchers develop bioinspired Bouligand structure for enhanced mechanical properties
Bouligand structures, found in natural materials like fish scales, lobster peritoneum and bones, are known for providing exceptional mechanical properties to biomaterials. While progress has been made in creating bioinspired materials, most research.....»»
Fish residues can compensate for raw materials shortages and improve our health in the bargain
More than a million tons of fish residues can rescue the food and cosmetic industries from raw materials shortages—and create new jobs. The key factors here are oils rich in omega-3, collagen and gelatin......»»
Animal behavior research better at keeping observer bias from sneaking in—but there"s still room to improve
Animal behavior research relies on careful observation of animals. Researchers might spend months in a jungle habitat watching tropical birds mate and raise their young. They might track the rates of physical contact in cattle herds of different dens.....»»

Oil palm plantations are driving massive downstream impact to watershed
The global demand for palm oil—the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick—is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainfores.....»»
Wildfires in wet African forests have doubled in recent decades, large-scale analysis finds
A new study presents the first large-scale analysis of fire patterns in West and Central Africa's wet, tropical forests. The number of active fires there typically doubled over 18 years, particularly in the Congo Basin. The increases are primarily du.....»»
Scientists advance research of harmful PFAS chemicals and their impacts
A bemused fishmonger at a seafood market in Portsmouth, N.H., weighed and packaged a dozen filets of fish and three lobster tails for his unusually exacting customers, Dartmouth researchers Celia Chen, Guarini, a research professor of biological scie.....»»
Why do male chicks play more than females? Study finds answers in distant ancestor
Play is widespread, but far from ubiquitous, across the animal kingdom. Especially common in mammals, play is also known to occur in taxa as diverse as birds, fish, octopuses, and even insects. But what is its function, given that natural selection n.....»»
