Drifter or Homebody? Study First to Show Where Whitespotted Eagle Rays Roam
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.
Crunch! Underwater Acoustics Expose ‘Shell-crushing’ Sounds in a Large Marine Predator
“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.

China’s ecological restoration projects deplete terrestrial water stores
Irvine, Calif., Sept. 10, 2020 – Through concerted, policy-driven efforts, China has converted large swaths of desert into grassland over the past few decades, but this success has come at a cost. In a study published recently in Nature Sustainability, scientists at the University of California, Irvine report that the Asian nation’s environmental reclamation programs have substantially diminished terrestrially stored water.
Bending the curve of biodiversity loss
A major new study suggests that without ambitious, integrated action combining conservation and restoration efforts with a transformation of the food system, turning the tide of biodiversity loss by 2050 or earlier will not be possible.
Land Development in New Jersey Continues to Slow
Land development in New Jersey has slowed dramatically since the 2008 Great Recession, but it’s unclear how the COVID-19 pandemic and efforts to fight societal and housing inequality will affect future trends, according to a Rutgers co-authored report. Between 2012 and 2015, 10,392 acres in the Garden State became urban land. That’s 3,464 acres a year – far lower than the 16,852 acres per year in the late 1990s and continuing the trend of decreasing urban development that began in the 2008 Great Recession.
Hots Dogs, Chicken Wings and City Living Helped Wetland Wood Storks Thrive
Using the Wood Stork, researchers compared city storks with natural wetland storks to gauge their success in urban environments based on their diet and food opportunities. Results provide evidence of how a wetland species persists and even thrives in an urban environment by switching to human foods like chicken wings and hots dogs when natural marshes are in bad shape. These findings indicate that urban areas can buffer a species from the unpredictability of natural food sources.
Consideration of both the potential and constraints of reforestation is needed to achieve climate mitigation goals: NUS-led study

Dolphin Calf Entangled in Fishing Line Only Lived Two Years Following Rescue
Researchers examined the outcome of an entangled bottlenose dolphin calf with monofilament fishing line wrapped tightly around its upper jaw. It was successfully disentangled and immediately released it back into its natural habitat. Surviving only two years, results showed long-term severe damage due to this entanglement including emaciation. There are about 1,000 bottlenose dolphins that live in the Indian River Lagoon, which also is a very popular location for recreational fishing.
For urban conservation, local resident involvement is key
Conservation projects in cities are most likely to succeed when nearby residents are part of the planning and design process and feel ownership over the projects, researchers who spent seven years studying conservation in Cleveland say.
Indigenous People Vital for Understanding Environmental Change
Grassroots knowledge from indigenous people can help to map and monitor ecological changes and improve scientific studies, according to Rutgers-led research. The study, published in the Journal of Applied Ecology, shows the importance of indigenous and local knowledge for monitoring ecosystem changes and managing ecosystems. The team collected more than 300 indicators developed by indigenous people to monitor ecosystem change, and most revealed negative trends, such as increased invasive species or changes in the health of wild animals. Such local knowledge influences decisions about where and how to hunt, benefits ecosystem management and is important for scientific monitoring at a global scale.
Biotelemetry Provides Unique Glimpse into Whitespotted Eagle Rays’ Behavior
