By deciphering the genetic code of the barbelled giant, scientists expect to better understand the secrets of the wels catfish's exceptionally rapid growth, enormous appetite and longevity.
Although less than one per cent of all water in the world is freshwater, it is what we drink and use for agriculture. In other words, it's vital to human survival. York University researchers have just created a publicly available water quality database for close to 12,000 freshwater lakes globally - almost half of the world's freshwater supply - that will help scientists monitor and manage the health of these lakes.
Innovative new projects using effluent to restore flow in rivers, like the Santa Cruz River Heritage Project, are showing almost immediate positive biodiversity effects, and the return of species (such as dragonflies, mayflies and caddisflies) to these rivers after very long dry spells can be incredibly fast.
Jellyfish could replace fish and chips on a new sustainable takeaway menu to help keep threatened species off the plate. University of Queensland researchers found 92 endangered and 11 critically endangered species of seafood were caught in oceans around the world after analysing global industrial fishing records.
Researchers have identified an invasive blood-sucking parasite on mud shrimp in the waters of British Columbia's Calvert Island. The discovery represents the northern-most record of the parasite on the West Coast and is likely an indication of its ability to spread without human transport.
A new study shows that despite global commitments to address plastic pollution, growth in plastic waste, or 'plastics emissions' continues to outpace reduction. What's more, the study shows that even if governments around the world adhere to their ambitious commitments to curb plastic pollution, annual plastic emissions may increase more than six-fold by 2030.
New research looks at the swimming and sinking kinematics of nine species of warm water pteropods (sea snails) to shed light on their ecology, predator-prey interactions, and vertical distributions. By using a high-speed stereophotogrammetry system, investigators were able to focus on how the shell shape, body geometry, and body size affect their swimming behavior from a fluid mechanics perspective, while image analysis and metabarcoding related swimming behaviors to night time and daytime vertical distributions.
Deep-sea coral reefs face challenges as changes to ocean chemistry triggered by climate change may cause their foundations to become brittle, a study suggests.
Current research suggests that more complex life-forms, including humans, evolved from a symbiosis event of Bacteria and another single-celled organism known as Archaea. However, evidence of a transition period in which the two organisms mixed where nowhere to be found. That is, until now. In the deep waters of the Black Sea, a team of scientists from NIOZ and Utrecht University found microbes that can make membrane lipids of unexpected origin.
Research led by ecologists at the University of Toronto examining plastic pollution entering oceans, rivers and lakes around the world annually, outlines potential impacts of various mitigation strategies over the coming decade. The researchers estimate the scale of human response needed to reduce future emissions and manage what's already floating around out there and recommend a fundamental shift to a framework based on recycling where end-of-life plastic products are valued rather than becoming waste.
