After Election: Making the Endangered Species Act More Effective
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.

Scientists are First in the World to Spawn Bonefish in Captivity
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.

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
Using uniquely coded transmitters and acoustic telemetry, a study is the first to characterize the ecology and fine-scale habitat use of whitespotted rays in Florida while also identifying areas of potential interactions between this species and multiple environmental threats.

Good Night? Satellite Data Uncovers Dolphins on the Move at Nighttime
More than 1,000 bottlenose dolphins live in Florida’s Indian River Lagoon year-round. Although extensively studied, what they do at nighttime is still a mystery. Using satellite telemetry, scientists provide the first documentation that these dolphins have a larger range that encompasses more habitats than previously thought. They regularly leave the brackish waters of the estuarine system and, not only travel into the ocean, but swim substantial distances – up to 20 kilometers – up freshwater rivers, creeks, and canals.

Monogamous Female Sea Turtles? Yes, Thanks to Sperm Storage
Female sea turtles mate multiply to ensure fertilization. A study of nesting loggerhead female sea turtles in southwestern Florida used genotyping to uncover how many fathers were represented in their nests. Surprisingly, scientists found that 75 percent of the female sea turtles had mated singly. No male was represented in more than one female’s clutches. Findings provide insights into the relative numbers of males present in the breeding population, which are hard to get because males never come ashore.
