A new study found that record-breaking whale entanglements in the Pacific Northwest were triggered by a unique marine heatwave, known as the 'Blob', which altered fish populations and habitats. The research has led to the development of online tools to help fishermen avoid entanglement risks.
New research found that male guppies exposed to predators have heavier brains than their counterparts living in predator-free conditions. This suggests a possible advantage under threat, allowing the fish to detect or react to predators better. In contrast, female guppies did not exhibit this pattern.
A new study in the Hudson-Raritan Estuary found that support for oyster restoration is linked to perceived risks to public health and the economy, rather than group membership. The research suggests that both conservationists and industry members may be receptive to similar appeals for oyster restoration projects.
Scientists from UC Santa Cruz and the Nature Conservancy released a report identifying lands in Florida that are potential targets for projects with multiple benefits, such as reduced flood exposure, conservation, and remediation of social vulnerability. The study proposes prioritizing property buyouts based on these factors to support...
The world lost more than twice as much interior forest area than it gained between 2000 and 2012, with a net loss of 3.76 million square kilometers. This resulted in a fragmentation of remaining forests, increasing ecological risks.
