FAU Lands $11 Million from U.S. Office of Naval Research for Oceanic Bioluminescence
FAU’s Harbor Branch Oceanographic Institute has landed an $11,179,001 four-year contract from the U.S. Office of Naval Research to develop a next-generation, high-intake, compact, bathyphotometer sensor for natural oceanic bioluminescence assessments. Bioluminescent creatures are found throughout marine habitats and their “glowing” energy released from chemical reactions is used to warn or evade predators, lure or detect prey and communicate with the same species. Research surrounding bioluminescence will soon serve as an important tool to protect U.S. coastlines.
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.

New study on migration success reinforces need for monarch butterfly milkweed habitat
A recently published study presents evidence that the migration success of monarchs hasn’t declined in recent years and thus cannot explain the steep decline in the monarch population over the last few decades. The study drew on data collected on 1.4 million monarch butterflies that were tagged in the United States Midwest from 1998 to 2015 and emphasizes the need for new monarch habitat.
Meet the hedge fund managers of avian world
In uncertain times, it makes sense to manage risk in your endeavors — whether it’s investing in money-making opportunities or deciding where to lay your eggs. Brood parasites are birds that are known to lay their eggs in other birds’ nests. Cowbirds and cuckoos are among the most famous examples of this group.
‘Insect apocalypse’ may not be happening in U.S.
Scientists have been warning about an “insect apocalypse” in recent years, noting sharp declines in specific areas — particularly in Europe. A new study shows these warnings may have been exaggerated and are not representative of what’s happening to insects on a larger scale.
Monarch butterflies raised in captivity may be worse at migrating south than wild monarchs raised outdoors

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.

Like Humans, Beluga Whales Form Social Networks Beyond Family Ties
A groundbreaking study is the first to analyze the relationship between group behaviors, group type, group dynamics, and kinship of beluga whales in 10 locations across the Arctic. Results show that not only do beluga whales regularly interact with close kin, including close maternal kin, they also frequently associate with more distantly related and unrelated individuals. Findings will improve the understanding of why some species are social, how individuals learn from group members and how animal cultures emerge.

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.

A return to the wild for better immune health
A research team led by the University of Adelaide has found that revegetation of green spaces within cities can improve soil microbiota diversity towards a more natural, biodiverse state, which has been linked to human health benefits.
In the study, published in the journal Restoration Ecology, researchers compared the composition of a variety of urban green space vegetation types of varying levels of vegetation diversity, including lawns, vacant lots, parklands, revegetated woodlands and remnant woodlands within the City of Playford Council area in South Australia.
Mammoths, mastodons and the fruit they left behind at Fermilab
If you live in the Chicago suburbs and have ever taken a walk on the Fermilab hike-and-bike trail along Batavia Road, you’ve probably noticed large trees with long, slender bean pods, which — even after they fall to the ground — are ignored by wildlife. Not that long ago, mammoths, mastodons and giant ground sloths roamed the Fermilab grounds and feasted on these bean pods, along with the fruit of two additional species that still can be found growing on site.
Cornell research traces how farmlands affect bee disease spread
A new Cornell University study on bees, plants and landscapes in upstate New York sheds light on how bee pathogens spread, offering possible clues for what farmers could do to improve bee health.
Oyster Farming and Shorebirds Likely Can Coexist
Oyster farming as currently practiced along the Delaware Bayshore does not significantly impact four shorebirds, including the federally threatened red knot, which migrates thousands of miles from Chile annually, according to a Rutgers-led study. The findings, published in the journal Ecosphere, likely apply to other areas around the country including the West Coast and Gulf Coast, where oyster aquaculture is expanding, according to Rutgers experts who say the study can play a key role in identifying and resolving potential conflict between the oyster aquaculture industry and red knot conservation groups.
