New research finds tropical forest disturbance goes beyond species loss and includes a shift towards smaller seeds and an increase in the proportion of trees dispersed by animals, impacting how the ecosystem functions. The findings are published in the British Ecological Society journal, Journal of Ecology.
They might not be as popular as jaguars and parrots, but fish hold the key to lots of the Amazon rainforest's secrets. Studying the different kinds of fish living in the region's lakes and rivers helps scientists understand how rainforest ecosystems are connected. An investigation of fish populations is helping scientists make a case that protecting one tiny corner of the Guiana Shield can help protect rivers and biodiversity across the Amazon.
In 1988, a 6.9 magnitude earthquake struck near the northern Armenian city of Spitak. The temblor destroyed cities and is estimated to have killed between 25,000 and 35,000 people, many of whom were schoolchildren. The latest findings from a long-term, UCLA-led study reveal that children who survived the quake and received psychotherapy soon after have experienced health benefits into adulthood.
How Did Dinosaur Parents Know When Their Kids Had a Fever? Prehistoric egg shells provide clues to dinosaurs' evolution from cold- to warm-blooded creatures.
Research by an international team of scientists led by University of New Mexico Professor Yemane Asmerom suggests contraction of the Intertropical Convergence Zone (ITCZ) during a warming Earth, leading in turn to drying of the Neotropics, including Central America, and aggravating current trends of social unrest and mass migration.
In her AAAS talk, ASU researcher Katie Cramer outlines the evidence of the long-ago human footprints that set the stage for the recent coral reef die-offs we are witnessing today. Her studies have examined the origins of Caribbean coral reef declines by tracking changes over the past 3,000 years in the composition of a variety of fossils found in reef sediment cores she collected from Panama, including coral skeletons, fish teeth, urchin spines, mollusk shells, and others.
Researchers from the school of Geographical Sciences at Guangzhou University have revealed the stark decline of China's intertidal wetlands by studying archives of satellite imaging data. The area of these wetlands reduced by 37.62% between the 1970s and 2015, placing these vulnerable yet valuable ecosystems and the species they support under increased pressure from anthropogenic development and future sea level rise.
A Michigan State University- and University of Maryland-led study featured on the cover of this week's Science magazine should sound alarm bells regarding the "biodiversity crisis" or the loss of wildlife around the world.
New research published in Nature Communications shows that the ability of tropical forests to lock up carbon depends critically upon a group of trees that possess a unique talent -- the ability to fix nitrogen from the atmosphere.
American consumers are hungry for more climate-friendly plant-based diets, but they need more information, according to a new survey by the Yale Program on Climate Change Communication and the Earth Day Network.
