New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
UT Arlington research finds wastewater treatment plants are still not effectively removing dangerous microplastics Despite advances in wastewater treatment, tiny plastic particles called microplastics are still slipping through, posing potential health and environmental hazards, according to new research from The University of Texas at Arlington. Because plastic is inexpensive to produce yet lightweight and sturdy, manufacturers have found it ideal for use in nearly every consumer good, from food and beverage packaging to clothing and beauty products. The downside is…
Farmers apply nitrogen fertilizers to crops to boost yields, feeding more people and livestock. But when there’s more fertilizer than the crop can take up, some of the excess can be converted into gaseous forms, including nitrous oxide, a greenhouse gas that traps nearly 300 times as much heat in the atmosphere as carbon dioxide. About 70% of human-caused nitrous oxide comes from agricultural soils, so it’s vital to find ways to curb those emissions. Before they can recommend practices…
Research team tests how stream contents and flow impact microplastic retention Microplastics, tiny plastic particles found in everyday products from face wash to toothpaste, are an emerging threat to health and ecology, prompting a research team to identify what keeps them trapped in stream ecosystems. Everyday actions like washing synthetic clothing and driving, which wears down tires, contribute to an accumulation of microplastics in environments from city dust to waterways. These plastics often carry toxic chemicals that can threaten the…
In the largest study of its kind, researchers at the Florida Museum of Natural History have used data from a 120-year-old program managed by the U.S. Department of Agriculture to quantify the effects of introduced species. The researchers included more than 5 million measurements from individual trees across much of eastern North America and showed the rate at which introduced species are spreading has increased over the last two decades. Additionally, native tree diversity is on the decline in areas…
Global bird sightings from citizen scientists and view into “climate niches” reveals unexpected risks for some birds. Biologists have long debated why some plants and animals can adjust to a wide range of climates, while others can’t. Understanding why could help conservation managers and decision makers identify which species are most vulnerable to climate change. A new study in Nature Communications by researchers at The University of Texas at Austin evaluated global distribution maps and other data for about 1500…
The ‘Barbarian Conspiracy’ of 367 CE was one of the most severe threats to Rome’s hold on Britain since the Boudiccan revolt three centuries earlier. Contemporary sources indicate that components of the garrison on Hadrian’s wall rebelled and allowed the Picts to attack the Roman province by land and sea. Simultaneously, the Scotti from modern-day Ireland invaded broadly in the west, and Saxons from the continent landed in the south. Senior Roman commanders were captured or killed, and some soldiers…
In the global carbon cycle microorganisms have evolved a variety of methods for fixing carbon. Researchers from Bremen and Taiwan have investigated the methods that are utilized at extremely hot, acidic and sulfur-rich hydrothermal vents in shallow waters off the island of Kueishantao, Taiwan. A team working with first author Joely Maak of MARUM – Center for Marine Environmental Sciences at the University of Bremen has now published their study in the professional journal Biogeosciences. Extremely harsh conditions can be…
New study uses modern molecular and evolutionary techniques to reassess a foundational, 67-year-old study in warblers A spat between birds at your backyard birdfeeder highlights the sometimes fierce competition for resources that animals face in the natural world, but some ecologically similar species appear to coexist peacefully. A classic study in songbirds by Robert MacArthur, one of the founders of modern ecology, suggested that similar wood warblers — insect-eating, colorful forest songbirds — can live in the same trees because…
Is sauerkraut more than just a tangy topping? A new University of California, Davis, study published in Applied and Environmental Microbiology suggests that the fermented cabbage could help protect your gut, which is an essential part of overall health, supporting digestion and protecting against illness. Authors Maria Marco, professor with the Department of Food Science and Technology, and Lei Wei, a postdoctoral researcher in Marco’s lab, looked at what happens during fermentation — specifically, how the metabolites in sauerkraut compared to those…
The sun may rise every morning, but the amount of sunlight reaching the Earth’s surface can substantially vary over decades, according to a perspectives article led by an international research team. The article, published on March 15 in Advances in Atmospheric Science, suggests that stages of “dimming” and “brightening” correspond with increased air pollution and implementation of clean energy solutions, respectively. “The amount of sunlight — which is solar radiative energy — we receive at the Earth’s surface is not…
New research explores geological processes along plate boundaries Being a geophysicist can sometimes feel like being a detective —uncovering clues, and then building a case based on the evidence. In a new article published in Science Advances, a collaborative team led by the Woods Hole Oceanographic Institution (WHOI), presents a never-before-seen image of an oceanic transform fault from electromagnetic (EM) data collected at the Gofar fault in the eastern Pacific Ocean. The National Science Foundation funded work reveals unexpected brine…
With a prestigious Max Planck Fellowship (2025–2028), microbiologist Gabriele Berg from the Leibniz Institute for Agricultural Engineering and Bioeconomy (ATB) is launching a research collaboration with chemist Markus Antonietti at the Max Planck Institute of Colloids and Interfaces. Together, they’re developing a solution to soil exhaustion and infertility: a custom-made soil created in the lab from plant residues, enriched with carefully selected microorganisms. This biologically active soil is designed to restore microbial balance, support plant health, capture CO₂—and ultimately break…

Urgent action is needed to protect endangered species, human health and industry from the impacts of the Caspian Sea shrinking, research led by the University of Leeds has found. Water levels in the Caspian Sea – the world’s largest landlocked water body – are getting lower, as hotter temperatures cause more water to evaporate than is flowing in. Even if global warming is limited to below 2°C, it is likely that the level of the Caspian Sea will decline by 5…
Researchers conduct batch adsorption testing in different soil types to understand the adsorption and aggregation behavior of nanoplastics in soil Plastics are everywhere—from packaging and textiles to electronics and medical devices. As plastic waste breaks down, it releases microscopic particles that can penetrate our ecosystems, hinder plant growth, and potentially transfer harmful pollutants to organisms, including humans. Therefore, these plastic particles are a potential threat to the ecosystem, especially in their nanoparticulate form (1–100 nm diameter), which can penetrate the…
