Iconic savanna mammals face genetic problems due to fences and roads
Whether by way of Attenborough, Disney or National Geographic, the iconic scene is familiar to many. The ground trembles and clouds of dust swirl as enormous hordes of large animals thunder across the African savanna, cross rivers en masse and are pi.....»»
Ocean currents threaten to collapse Antarctic ice shelves, study finds
A new study published in Nature Communications has revealed that the interplay between meandering ocean currents and the ocean floor induces upwelling velocity, transporting warm water to shallower depths. This mechanism contributes substantially to.....»»
Certified timber harvesting of tropical forests proves beneficial for gorillas and elephants
Forest Stewardship Council (FSC)-certified timber harvesting areas in Gabon and Congo boast a greater abundance of larger mammals, such as leopards, gorillas, and elephants, than non-FSC forests......»»
Heat from El Niño can warm oceans off West Antarctica—and melt floating ice shelves from below
As snow falls on Antarctica, layers build up and turn to ice. Over time, this compressed snow has become a continent-sized glacier, or ice sheet. It's enormous—almost double the size of Australia and far larger than the continental United States......»»
Rising sea surface temperatures have led to profound changes in macroalgae communities over the last 40 years: Study
A study conducted off the coast of Biscay shows that cold-affinity algae species are gradually being replaced by warm-affinity ones......»»
New young and warm Jupiter-like exoplanet detected
An international team of astronomers reports the detection of a new young and warm exoplanet orbiting a distant star. The newfound alien world, designated TOI-4862 b (or NGTS-30 b), is similar in size and mass to Jupiter. The finding was published Ap.....»»
Mediterranean marine worm has developed eyes "as big as millstones"
Scientists are amazed at the discovery of a bristle worm with such sharp-seeing eyes that they can measure up to those of mammals and octopuses. Researchers from the University of Copenhagen and Lund University suspect that these marine worms may hav.....»»
Rare Javan rhino calf spotted in Indonesia
A new Javan rhinoceros calf has been spotted at an Indonesian national park, giving hope for the conservation of one of the world's most endangered mammals......»»
Tiny cracks in rocks may have concentrated chemicals needed for life
The gentle flow of warm fluids could have given pre-life chemistry a boost. Enlarge / Active geology could have helped purify key chemicals needed for life. (credit: Christof B. Mast) In some ways, the origin of life is.....»»
Unlocking Arctic mysteries: How melting ice shapes our climate
Recent decades have witnessed rapid changes in the Arctic climate, with warming rates surpassing global averages by three to four times. This puzzling "Warm Arctic, Cold Eurasia" climate phenomenon has profound implications, sparking scientific curio.....»»
Tropical cyclones may be an unlikely ally in the battle against ocean hypoxia
Tropical cyclones, also known as hurricanes and typhoons, are meteorological phenomena that occur over tropical and subtropical oceans experiencing low atmospheric pressure, where water vapor from the warm oceans condenses to produce spiraling cloud.....»»
Atmospheric scientists link Arctic sea loss ice to strong El Niño events
El Niño, a climate pattern where warm waters in the eastern Pacific fuel hotter weather, is finally beginning to wane after bringing a long stretch of record heat and heavy precipitation across the world since last summer......»»
Small birds spice up the already diverse diet of spotted hyenas in Namibia
Spotted hyenas are known for hunting (or scavenging) larger mammals such as antelopes and occasionally feed on smaller mammals and reptiles. Being flexible in the choice of prey is a strategy of generalists—and this even extends to small passerine.....»»
Ancient isolation"s impact on modern ecology: How deep biogeographic divides drive divergent evolutionary paths
A new study led by Michigan State University researcher Peter Williams sheds light on the profound influence of deep geographic isolation on the evolution of mammals. Published in Nature Communications, the research reveals how long-lasting separatio.....»»
Invasive Pacific oyster proliferation during Blob marine heat wave portends similar events as seas warm
Pacific oysters, non-native to the United States but farmed in the U.S. for aquaculture, are an invasive species. During the Pacific Blob heat wave in the mid-2010s, as sea temperatures in Washington state's Puget Sound rose to 3°C above average, th.....»»

Killer whales use specialized hunting techniques to catch marine mammals in the open ocean
Killer whales foraging in deep submarine canyons off the coast of California represent a distinct subpopulation that uses specialized hunting techniques to catch marine mammals, Josh McInnes at the University of British Columbia and colleagues report.....»»
Genetic basis for the evolution of hair discovered in the clawed frog
The development of hair was of central importance for the evolution of mammals and, thus, also of humans. However, the evolutionary origin of the genetic program of hair was previously unknown. An international research team led by Leopold Eckhart fr.....»»
