The estimated number of monarch butterflies migrating to Mexico for winter has reached its second-lowest level ever for the 2023 to 2024 overwintering season. The estimate, based on the size of the butterflies’ hibernating forest area, has dropped by about 59% from the previous year, according to officials. Experts are pointing to extensive heat and […]
Sea otters started recolonizing their former habitat in a central California coastal estuary several decades ago, and erosion has since slowed by as much as 90 percent, according to a new study. Elkhorn Slough is an estuary dominated by salt marshes. Its marsh edges and creek banks had suffered from erosion, but when the sea […]
Quick Key Facts What Are ‘Wetlands’? A wetland is exactly what it sounds like: ground that is covered by or saturated with water for all or part of the year. The water that makes a wetland can come from a variety of different sources, including ocean tides; freshwater sources like lakes, rivers, or ponds; underground […]
A first-of-its-kind study by researchers from the Wildlife Conservation Society (WCS) and the University of Massachusetts Amherst (UMass Amherst) has found that older elephants will have less chance of survival as the climate warms, and this will reverberate throughout the surrounding landscape. The research team has developed models for potential mitigation scenarios, which have already […]
The National Oceanic and Atmospheric Administration’s (NOAA) Coral Reef Watch has added three new alert levels to track potential risks to coral reefs and other marine life following the hottest year on record. Previously, Coral Reef Watch’s Bleaching Alert Area product stopped at a Bleaching Alert Level 2, which warned of a “risk of reef-wide […]
A new study by a team of scientists with the Conservation Ecology Research Unit at South Africa’s University of Pretoria has found that the best way to keep elephant numbers stable is to let them roam freely in protected areas connected to buffer zones, rather than in “fortress” conservation areas where they have less space. […]
An analysis of data from the Royal Society for the Protection of Birds (RSPB) has found that fewer wild birds are visiting gardens in the UK. RSPB analyzed data from its annual Big Garden Birdwatch, which kicks off in late January each year since 1979. The Big Garden Birdwatch asks participants to spend at least […]
A new study using model predictions has uncovered a likely rapid accumulation of microplastics around Santa Cruz Island, an island in the Galápagos National Park of Ecuador. The model predictions point to an accumulation of plastics sized from 1 micron to less than 5 millimeters in waters around the human-populated island. The researchers behind the […]
In a major breakthrough, the first successful southern white rhino in vitro fertilization has been carried out by scientists. It could mean hope in the quest to save the northern white rhino, whose last remaining members — cousins of the southern rhino — are both female. Neither of the two northern white rhinos, Najin and […]
