( University of Arizona ) Western butterfly populations are declining at an estimated rate of 1.6% per year, according to a new report to be published this week in Science. The report looks at more than 450 butterfly species, including the western monarch, whose latest population count revealed a 99.9% decline since the 1980s.
Managing invasive species--not eliminating them altogether--is a better use of time and conservation resources in many cases, according to a study led by a University of Alberta biologist.
An exquisitely detailed global ocean model simulation from the National Center for Atmospheric Research (NCAR) has given scientists rare insight into where baby sea turtles may go in their "lost years" after they scramble off the sandy beaches where they are born and swim into the open ocean.
Nokia today announced that it will reduce emissions by 50% across both its own operations and products in use by 2030. The company’s new Science Based Targets (SBTs) fulfill its commitment to recalibrate in line with a 1.5°C global warming scenario.
Clemson University scientists have linked climatic fluctuations over the past one and a quarter-century with flower color changes.
Endangered Southern Resident killer whales prey on a diversity of Chinook and other salmon. The stocks come from an enormous geographic range as far north as Alaska and as far south as California's Central Valley, a new analysis shows.
Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it's uncertain whether chemicals applied to land decades ago can continue to influence the soil's health after switching to organic management.
Researchers are in the search for generalisable rules and patterns in nature. Biogeographer Julia Kemppinen together with her colleagues tested if plant functional traits show similar patterns along microclimatic gradients across far-apart regions from the high-Arctic Svalbard to the sub-Antarctic Marion Island. Kemppinen and her colleagues found surprisingly identical patterns.
Rising temperatures could reduce the efficiency of food chains and threaten the survival of larger animals, new research shows.
UNSW and The International Union for the Conservation of Nature (IUCN) have launched the world’s first Global Typology of Ecosystems, the first-ever comprehensive system for classifying and mapping all ecosystems on Earth based on both their functions and composition. The typology allows for more coordinated and effective approaches to conservation management.
