Published Male southern elephant seals are picky eaters
(via sciencedaily.com) Original source New research suggests these large marine mammals are extremely fussy and only eat their favorite foods.
Published Conflict in full swing: Forest bats avoid large areas around fast-moving wind turbines
(via sciencedaily.com) Original source Not only do many bats die at wind turbines, the turbines also displace some species from their habitats over large areas. When the turbines are in operation at relatively high wind speeds, the activity of bat species that hunt in structurally dense habitats such as forests drops by almost 80 per cent within a radius of 80 to 450 meters around the turbine.
Published The choreography connecting kelp forests to the beach
(via sciencedaily.com) Original source A new study uncovers a symphony of synchrony between the kelp forest and beach, with broader implications for the beach food web as the climate changes.
Published Microbial awakening restructures high-latitude food webs as permafrost thaws
(via sciencedaily.com) Original source Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.
Published Understanding climate mobilities: New study examines perspectives from South Florida practitioners
(via sciencedaily.com) Original source A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.
Published From NYC to DC and beyond, cities on the East Coast are sinking
(via sciencedaily.com) Original source Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.
Published Western Cascades landscapes in Oregon historically burned more often than previously thought
(via sciencedaily.com) Original source Forests on the west slope of Oregon's Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought.
Published How technology and economics can help save endangered species
(via sciencedaily.com) Original source A lot has changed in the world since the Endangered Species Act (ESA) was enacted 50 years ago in December 1973. Experts are now discuss how the ESA has evolved and what its future might hold.
Published Insects already had a variety of defense strategies in the Cretaceous
(via sciencedaily.com) Original source Analyses of amber show that insect larvae were already using a wide variety of tactics to protect themselves from predators 100 million years ago.
Published How national policies affect forests in border regions
(via sciencedaily.com) Original source How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
Published Finding new ways to adapt to a growing weather threat
(via sciencedaily.com) Original source Research reveals a steady increase in the number of people at risk from tropical cyclones and the number of days per year these potentially catastrophic storms threaten health and livelihoods. The findings could help relief agencies, development banks, and other organizations plan more effective strategies for mitigating extreme weather impacts.
Published Reduced air pollution during pandemic points to way to preserve Himalayan glaciers
(via sciencedaily.com) Original source Reducing air pollution to levels similar to those during the coronavirus pandemic could protect the glaciers in the Himalayas and prevent them from disappearing by the end of the century. This is the conclusion reached by an international research team analyzing the situation during the COVID-19 lockdown in 2020.
Published World's smallest 'fanged' frogs found in Indonesia
(via sciencedaily.com) Original source Researchers have identified a species of frog new to science. The Indonesian amphibian is the size of a quarter, unlike its two-pound cousins, and has tiny fangs. Nearly uniquely among amphibians, they lay their eggs on the leaves of trees, and the males guard and tend to the nests.
Published Mesopotamian bricks unveil the strength of Earth's ancient magnetic field
(via sciencedaily.com) Original source Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study.
Published Little bacterium may make big impact on rare-earth processing
(via sciencedaily.com) Original source A tiny, hard-working bacterium -- which weighs one-trillionth of a gram -- may soon have a large influence on processing rare earth elements in an eco-friendly way.
Published Exoplanets' climate -- it takes nothing to switch from habitable to hell
(via sciencedaily.com) Original source The Earth is a wonderful blue and green dot covered with oceans and life, while Venus is a yellowish sterile sphere that is not only inhospitable but also sterile. However, the difference between the two bears to only a few degrees in temperature. A team of astronomers has achieved a world's first by managing to simulate the entirety of the runaway greenhouse process which can transform the climate of a planet from idyllic and perfect for life, to a place more than harsh and hostile. The scientists have also demonstrated that from initial stages of the process, the atmospheric structure and cloud coverage undergo significant changes, leading to an almost-unstoppable and very complicated to reverse runaway greenhouse effect. On Earth, a global average temperature rise of just a few tens of degrees, subsequent to a slight rise of the Sun's luminosity, would be sufficient to initiate this phenomenon and to make our planet inhabitable.
Published Global inventory of sound production brings us one step closer to understanding aquatic ecosystems
(via sciencedaily.com) Original source Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.
Published Some coral species might be more resilient to climate change than previously thought
(via sciencedaily.com) Original source Some coral species can be resilient to marine heat waves by 'remembering' how they lived through previous ones, research suggests.
Published Hotter weather caused by climate change could mean more mosquitoesv
(via sciencedaily.com) Original source Research along James River in Richmond suggests that climate change could shorten window for predators to prey on larvae.
Published Wildfires increasing across Eastern U.S.
(via sciencedaily.com) Original source Researchers examined 36 years of wildfire data in the eastern United States, focusing on fires that burned large areas. The overall trend for the region showed an increase in fire size, frequency, and shifts in seasonality and highlights a need for proactive management and individual preparedness for those living in this populous part of the country.
