CITRIS researchers will implant 40 to 50 anadromous steelhead trout with acoustic tags to determine how much water they need in order to thrive.
Officials from the U.S. Fish and Wildlife Service (FWS) are estimating that over 10,000 migrating birds have died so far this year because of reduced water flow to the Lower Klamath National Wildlife Refuge in Oregon and California. Officials say the final death toll may be close to 20,000 birds.
A species of lizard is now extinct from the Hawaiian Islands, making it the latest native vertebrate species to become extirpated from this tropical archipelago.
After 25 years, former waste dump converted to endangered wildlife habitat in Guam.
More than 99 percent of Antarctic blue whales were killed by commercial whalers during the 20th century, but the first circumpolar genetic study of these critically endangered whales has found a surprisingly high level of diversity among the surviving population of some 2,200 individuals.
The Department of Justice and the Department of the Interior recently announced the arrest of seven people charged with trafficking endangered black rhinoceros horns.
Both climate change and humans were responsible for the extinction of some large mammals, according to research that is the first of its kind to use genetic, archeological, and climatic data together to infer the population history of large Ice-Age mammals.
When a species recovers enough to be removed from the federal endangered species list, the public trust doctrine – the principle that government must conserve natural resources for the public good – should guide state management of wildlife, scientists say.
For decades, scientists have believed that a relationship exists between how much biomass plant species produce and how many species can coexist. Stanley Harpole, assistant professor in the Department of Ecology, Evolution, and Organismal Biology at Iowa State University, was part of the team researching productivity and richness, and he says the research doesn’t support that relationship.
U.S. President Barack Obama announced diplomatic measures the United States will take against Iceland to condemn its whaling activities.
In parts of the world still rich in biodiversity, separating natural habitats from high-yielding farmland could be a more effective way to conserve wild species than trying to grow crops and conserve nature on the same land, according to a new study published today in the journal Science.
It reveals that, in 2008, the seal hunt generated only $513,000 – a poor comparison to seal-watching, which netted $2 million in direct tourism expenditure in the same period
Results from the first study of the Asian longhorned beetle (ALB) in forests show that the invasive insect can easily spread from tree-lined city streets to neighboring forests.
Panda poop contains bacteria with potent effects in breaking down plant material in the way needed to tap biomass as a major new source of “biofuels” produced not from corn and other food sources, but from grass, wood chips and crop wastes, scientists reported.
Rodger Dale DeVries, 73, a resident of Jenison, Mich., has pleaded guilty to illegally importing a polar bear trophy mount in 2007 from Canada into Michigan in violation of the Marine Mammal Protection Act.
Recent study of grasslands shows that species variety more important to ecosystem services than previously thought.
The team’s analysis—published in a recent issue of Science magazine’s Policy Forum—is the first study of global tuna and billfish populations using the methods of the International Union for Conservation of Nature (IUCN).
The study, say the authors, will help to conserve some of the world’s most important coral reefs by identifying reef systems where biodiversity is high and stress is low, ecosystems where management has the best chance of success.
Hunters have been credited with being strong conservation advocates for numerous game species in multiple countries. Would initiating a wolf hunt invoke the same advocacy for the carnivores?
The University of Denver (DU) Sturm College of Law Environmental Law Clinic filed a federal lawsuit aiming to protect the porbeagle shark from overfishing that has pushed the species to the brink of extinction and left it in need of federal protection, the students say.
