Among pet snakes and lizards, the biggest-selling species are also the most likely to be released by their owners -- and to potentially become invasive species, according to a Rutgers study published today in the Journal of Applied Ecology. The study by Rutgers University-New Brunswick ecologists provides new clarity on how and why the exotic pet trade has become the primary venue by which reptiles and amphibians arrive in non-native lands, the first step to becoming ecologically damaging invaders.
Studying the effects of contraceptive medications on feral cat populations is difficult, but relying on standard laboratory settings is unrealistic. That's why a group of University of Illinois researchers created a unique study environment designed to bridge the gap between the lab and the real world. In short, it's a cat wonderland in which resident cats help to advance science.
The Southern California coast harbors some of the world's highest concentrations of an algal toxin perilous to wildlife and people. The most thoroughgoing assessment of the problem shows it's getting worse due to manmade and natural conditions.
A new large-data study of bivalves and gastropods in the Atlantic Ocean suggests laziness might be a fruitful strategy for survival of individuals, species and even communities of species.
New findings reveal that earlier springs and hotter summers in the northeastern U.S. are making resident lobsters increasingly susceptible to epizootic shell disease, a condition that has depleted the southern New England population and severely impacted the local lobster fishery.
Fisheries management has often been characterized by regulatory policies that result in panaceas -- broad based policy solutions that are expected to address several problems, which result in unintended consequences. An international research team shows how one size fits all policies like individual transferable quotas may be doomed from the onset, as these policies perpetuate 'the panacea mindset.' The team calls for a more customized policy approach in a new piece that will be published this week in the Proceedings of the National Academy of Sciences.
Climate change and other external forces are causing rapid marine community shifts in Japan's coastal ecosystems. Better understanding of species distribution dynamics, as driven by these factors, can improve conservation efforts and climate change management.
Many people rely on contact lenses to improve their vision. But these sight-correcting devices don't last forever and they are eventually disposed of in various ways. Now, scientists are reporting that throwing these lenses down the drain at the end of their use could be contributing to microplastic pollution in waterways. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
Dartmouth scientists have created a more sustainable feed for aquaculture by using a marine microalga co-product as a feed ingredient. The study is the first of its kind to evaluate replacing fishmeal with a co-product in feed designed specifically for Nile tilapia. The results are published in the open access journal, PLOS ONE.
Scientists have found that sunscreen from bathers releases significant quantities of polluting TiO2 (titanium dioxide) into the sea. This has the potential to harm marine life. This work, which comes from research on beaches in the South of France, was presented at the Goldschmidt geochemistry conference in Boston (see below).
