Study reveals how climate change can significantly impact one of the world’s most important carbon-rich ecosystems
Researchers from the University of Portsmouth say a ‘one size fits all’ approach to preserving mangrove forests will not work
Virtual reality gives humans a turtle’s-eye view of wildlife
A virtual reality simulation designed by a University of Oregon professor could help spur people to environmental action. Participants in Project Shell don a virtual reality headset and take on the body of a loggerhead sea turtle, sporting flippers instead of arms. During a 15-minute immersive experience, they journey from a hatchling to an adult turtle, dodging hazards like ships and wayward fishing gear.
Monarch butterfly populations are thriving in North America
For years, scientists have warned that monarch butterflies are dying off in droves because of diminishing winter colonies. But new research from the University of Georgia shows that the summer population of monarchs has remained relatively stable over the past 25 years.
Shinnecock Bay Recognized as A New Global “Hope Spot”
Shinnecock Bay on the south shore of Long Island, New York, is being named a new “Hope Spot” by Mission Blue, an international organization that supports the protection of oceans worldwide. This distinction is the result of a decade of restorative work led by Stony Brook University scientists.
The space between us
Tree beta diversity — a measure of site-to-site variation in the composition of species present within a given area — matters more for ecosystem functioning than other components of biodiversity at larger scales. The finding has implications for conservation planning.
Scavengers can be picky eaters
A recent study conducted by researchers at the University of Georgia found that when presented with a smorgasbord of options, vertebrate scavengers were selective about what or whom they ate—providing insight into how nutrients can cycle through food webs.
U.S. Must Ramp up Ocean Conservation to Meet Global MPA Standards
A new analysis of marine protected areas (MPAs) reveals that many important ocean regions off mainland United States are significantly unprotected – with large portions of the coast having only five percent or less of its area conserved and a vast majority of the Mid-Atlantic coast unprotected.
These stunning 3D models of coral reefs are a crucial research tool
Martínez Quintana has created stunning 3D digital models that visualize the surface of coral reefs in painstaking detail. The artful re-creations aren’t just beautiful: They’re also filled with data on the distribution of young corals, known as recruits, that scientists are analyzing.
Global Bird Populations Steadily Declining
Staggering declines in bird populations are taking place around the world. So concludes a study from scientists at multiple institutions, published today in the journal Annual Review of Environment and Resources. Loss and degradation of natural habitats and direct overexploitation of many species are cited as the key threats to avian biodiversity. Climate change is identified as an emerging driver of bird population declines.

The effects of embodying wildlife in virtual reality on conservation behaviors
AbstractEfforts to mitigate environmental threats are often inversely related to the magnitude of casualty, human or otherwise. This “compassion fade” can be explained, in part, by differential processing of large- versus small-scale threats: it is difficult to form empathic connections…
Improving Georgia land conservation through algorithms
A team of University of Georgia researchers has created a model to help land developers and public officials identify the land that is best suited for conservation. Led by Fabio Jose Benez-Secanho, a former UGA graduate student, and Puneet Dwivedi, associate professor in the Warnell School of Forestry and Natural Resources, this first-of-its-kind algorithm considers a variety of factors not included in other models when calculating the value of land for conservation.

As invasive carp continue to pose ecological and economic threats to the Upper Mississippi River Basin, researchers at West Virginia University hope to uncover ways to minimize the species’ expansion.
Novel Tag Provides First Detailed Look into Goliath Grouper Behavior
A study is the first to reveal detailed behavior of massive goliath groupers. Until now, no studies have documented their fine-scale behavior. What is known about them has been learned from divers, underwater video footage, and observing them in captivity. Using a multi-sensor tag with a three axis accelerometer, gyroscope and magnetometer as well as a temperature, pressure and light sensor, a video camera and a hydrophone, researchers show how this species navigates through complex artificial reef environments, maintain themselves in high current areas, and how much time they spend in different cracks and crevices – none of which would be possible without the tag.

Genotyping Reveals Significance of Mesophotic Reefs for Florida Keys’ Coral Recovery
Researchers are the first to compare the genetic structure and genomic diversity of paired shallow and upper mesophotic coral sites in the Northern and Southern Dry Tortugas and the Lower and Upper Florida Keys. Results suggest that while vertical connectivity between paired shallow and mesophotic populations can vary, certain mesophotic coral populations are important for maintaining the long-term survival of this ecologically important coral species throughout the Florida Keys and should be considered in future management strategies.

Low-cost 3D Method Rapidly Measures Disease Impacts on Florida’s Coral Reefs
A low-cost and rapid 3D technique is helping scientists to gain insight into the colony- and community-level dynamics of the poorly understood stony coral tissue loss disease responsible for widespread coral death throughout the Tropical Western Atlantic. They adapted Structure-from-Motion (SfM) photogrammetry to generate 3D models for tracking lesion progression and impacts on diseased coral colonies. They combined traditional diver surveys with 3D colony fate-tracking to determine the impacts of disease on coral colonies throughout Southeast Florida.

What’s Killing Coral Reefs in Florida is Also Killing Them in Belize
Only 17 percent of live coral cover remains on fore-reefs in Belize. A study finds new evidence that nitrogen enrichment from land-based sources like agriculture run-off and sewage, are significantly driving macroalgal blooms to increase on the Belize Barrier Reef and causing massive decline in hard coral cover. With only 2 percent of hard coral cover remaining in the Florida Keys National Marine Sanctuary, it’s too late to save that reef, but there’s still hope for the Belize Barrier Reef.

Undeniably the shark movie to end all shark movies, the 1975 blockbuster, Jaws, not only smashed box office expectations, but forever changed the way we felt about going into the water – and how we think about sharks.
Baylor Study Evaluates Biodiversity Impacts of Alternative Energy Strategies
Climate change mitigation efforts have led to shifts from fossil-fuel dependence to large-scale renewable energy. However, renewable energy sources require significant land and could come at a cost to ecosystems. A new study led by Ryan McManamay, Ph.D., assistant professor of environmental science at Baylor University, evaluates potential conflicts between alternative energy strategies and biodiversity conservation.

Iconic bird makes its home on campus
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.

Health Status of Vulnerable Gopher Tortoises Revealed in Southeastern Florida
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.
