Many seabirds in the Northern Hemisphere are struggling to breed — and in the Southern Hemisphere, they may not be far behind. These are the conclusions of a study, published May 28 in Science, analyzing more than 50 years of breeding records for 67 seabird species worldwide.
Adding wheat can boost yields, increase economic return, and improve soil
With its tree-laden campus and adjacent protected natural reserves, UCI enjoys being home to a great variety of bird species. One particular raptor continues to capture the attention of the many avid birders in Orange County: the white-tailed kite. This iconic bird of Orange County – named for its ability to hover in the air while hunting –nearly went extinct throughout California in the early 1900s due to human-related threats.
New research published in special issue of Sustainability co-edited by NAU researcher finds that biodiversity commitments will be key to freshwater protection
In previously unstudied gopher tortoise aggregations, researchers found that overall, 42.9 percent had circulating antibodies to an infectious bacterium that causes upper respiratory tract disease. Physical examination showed that 19.8 percent had clinical signs consistent with upper respiratory tract disease and 13.2 percent had some form of physical abnormality. None of the tortoises tested positive for Ranavirus or Herpesvirus, which represents important baseline data, since these viruses are thought to be emerging pathogens of other tortoise and turtle species.
A proposal to conduct the first comprehensive assessment of groundwater biodiversity in the central and eastern United States has earned a University of Alabama in Huntsville (UAH) assistant professor of biological science a five-year, $1.029 million National Science Foundation (NSF) CAREER award.

For the past 50 years, the U.S. Fish and Wildlife Service (USFWS) has been assembling counts of bald eagle nests to track the triumphant recovery of America’s national symbol. But in its new bald eagle population report – tabulated with the help of results using eBird data from the Cornell Lab of Ornithology – the USFWS found many more eagles than previously thought to exist in the Lower 48 states.
Why are “ghost forests” filled with dead trees expanding along the mid-Atlantic and southern New England coast? Higher groundwater levels linked to sea-level rise and increased flooding from storm surges and very high tides are likely the most important factors, according to a Rutgers study on the impacts of climate change that suggests how to enhance land-use planning.
Using NASA satellite images and machine learning, researchers with The University of Texas at Austin have mapped changes in the landscape of northwestern Belize over a span of four decades, finding significant losses of forest and wetlands, but also successful regrowth of forest in established conservation zones that protect surviving structures of the ancient Maya.

The U.S. Fish and Wildlife Service is reaching the end of a public debate on migratory bird protections — a debate that has focused on a Trump administration-imposed restriction to the Migratory Bird Treaty Act. The Trump rule, which the…
It’s made for long-distance travel, yet movement patterns of the whitespotted eagle ray remain a mystery. Between 2016 and 2018, scientists fitted 54 rays with acoustic transmitters and tracked them along both the Gulf of Mexico and Atlantic coasts of Florida, which differ in environmental characteristics. Results of the study reveal striking differences in travel patterns on the Atlantic coast compared to the Gulf coast. Findings have significant conservation and adaptive management implications for this protected species.
“Shell-crushing,” an explosive sound, occurs when marine animals crack open hard shells like clams to eat the edible tissue. There hasn’t been any data to support this feeding noise, until now. A study is the first to quantify these sounds using underwater acoustics in a marine animal in a controlled setting. Scientists know what type of shell a ray is eating based on the sound it makes and show it’s audible above ambient noise in lagoons out to 100 meters.

How the larvae of colorful clownfish that live among coral reefs in the Philippines are dispersed varies widely, depending on the year and seasons – a Rutgers-led finding that could help scientists improve conservation of species. Right after most coral reef fish hatch, they join a swirling sea of plankton as tiny, transparent larvae. Then currents, winds and waves disperse them, frequently to different reefs.
Second only to the spiny lobster, the queen conch is a prized delicacy long harvested for food and is revered for its beautiful shell. Conch populations have dwindled so low, creating a dire and urgent situation in ecological and economic terms. To preserve this most significant molluscan fishery in the Caribbean, the world’s leading expert on queen conch aquaculture has published an 80-page, step-by-step user manual that provides complete illustrations and photos of how to culture and restore the queen conch.
Conservation of fish and other marine life migrating from warming ocean waters will be more effective and also protect commercial fisheries if plans are made now to cope with climate change, according to a Rutgers-led study in the journal Science Advances.
Scientists from the Cornell Lab of Ornithology and Colorado State University used observations from the Lab’s eBird citizen-science program to estimate the seasonal species richness of nocturnally migrating passerines within 333 well surveyed urban areas in the contiguous U.S. “Richness” is defined as the number of different species in an area.
Using active acoustic telemetry and sonar data, a study provides the first detailed documentation of a shallow water fish diving 450 feet deep to spawn. Prior research has shown that bonefish dive about 164 feet to spawn, but this new and unprecedented study reveals that they reached depths of 450 feet, and moved below 325 feet for two hours before spawning in a rush upward to 220 feet deep.
The findings of a new report suggest that integrated strategies across food production, biodiversity, climate, and diets can meet the objectives of the Paris Agreement and the Sustainable Development Goals (SDGs).
A new report called Innovative Finance for Conservation: Roles for Ecologists and Practitioners, explores how private investment could boost conservation in a big way.
A collaboration between researchers from Cornell University and the University of Wisconsin-Madison has found that small, community-based reserves in Thailand’s Salween River Basin are serving as critical refuges for fish diversity in a region whose subsistence fisheries have suffered from decades of overharvesting.
A new study confirmed that the rabbit-sized rodent sequesters poison from the bark of Acokanthera schimperi, known as the poison arrow tree, into specialized fur for defense. The researchers also discovered an unexpected social life—the rats appear to be monogamous and may even form small family units with their offspring.
Scientists tagged and released a young, rare female smalltooth sawfish — a significant step for sawfish research and recovery efforts in Florida. The 10-year acoustic tag is a major milestone in providing crucial capacity to tell where these mysterious and endangered fish are headed in the future.
Following the presidential election, a leading group of scientists are making the case that a “rule reversal” will not be sufficient to allow the Endangered Species Act to do its job of protecting species. Instead, they’re calling for deeper improvements to the rules the U.S. Fish & Wildlife Service and the National Marine Fisheries Service use to apply the law–aiming to make the Act more effective and to gain bipartisan and industry support in an era of accelerating climate change.
The team’s analysis and policy recommendations were published in the journal Science.
A rare study shows how one of Georgia’s barrier islands provides a safe haven for gopher tortoises and gives researchers at the University of Georgia evidence to prove species relocation is an effective conservation tool.
Research shows willow trees may pair well with grass crops in alley cropping systems
High yields, conservation benefits seen from well-managed perennial groundcover
Fossil records of bonefish go back 138 million years, but large gaps about their biology remain. In just four years, scientists have successfully spawned bonefish in captivity and have figured out their life cycle to help inform management and conservation of this revered fishery. In the Florida keys alone, the annual economic impacts exceed $465 million. Florida’s recreational and commercial fishing industries and associated businesses account for billions of dollars that drive the economic engine for the state each year and contribute to hundreds of thousands of jobs.
Restoration efforts can potentially be 13 times more cost-effective when it takes place in the highest priority locations, according to a new landmark study.
For the first time, a research team has obtained high resolution sedimentary core samples from Lake Tanganyika. The samples show that high frequency variability in climate can lead to major disruptions in how the lake’s food web functions. The changes could put millions of people at risk who rely on the lake for food security. The team says the findings are a critical building block toward research-informed policymaking in the Lake Tanganyika region.
