The policy landscape for protecting honeybees from pesticides has just become a little more complicated, thanks to a new study suggesting that the sheer diversity of pesticides may be more of a problem than particular products. Another key finding: Certain fungicides long thought to be harmless to the bees are in fact fairly toxic to them. For full story, click here.

Researchers from Utah State University have developed a mathematical model for the management of wetlands. The computer model can recommend actions, such as when to begin invasive plant control, to help maintain wetland habitats. The details are in a paper just published in the journal Water Resources Research. Managing wetlands is a difficult job, especially as many states’ water supplies drop. The Bear River Migratory Bird Refuge is a 74,000-acre wildlife refuge in Utah. The refuge is home to many migratory bird species and other animals. Proper management is necessary to protect all of the unique birds that pass through but funding is limited. A team of researchers developed a mathematical model to help wetland managers better prioritize actions that will have the greatest impact. The computer model calculates the weighted usable area, or WU, of Utah’s wetlands. WU is a measure of the amount of space suitable for migratory birds based on factors such as water level and type of vegetation. The model can then recommend actions that will best increase the WU of the area. For full story, click here.

The Sierra Nevada yellow-legged frog was once one of the most abundant amphibians in that western mountain range. But the animal has disappeared from 93 percent of its historical range, leading it to be added to the endangered species list in 2014 by the US Fish and Wildlife Service. But there might be hope for the hoppers yet. For full story, click here.
Service Acts to Prevent Harm to Native Wildlife from 11 Nonnative Species
Contact: Christina Meister – U.S. Fish and Wildlife Service – September 29, 2016
The U.S. Fish and Wildlife Service today took action to help ensure 10 nonnative freshwater fish species and one nonnative freshwater crayfish species do not become established in the United States and damage native wildlife and habitats. In a final rule that will take effect 30 days after the date of publication in the Federal Register, the Service listed the crucian carp, Prussian carp, Eurasian minnow, roach, stone moroko, Nile perch, Amur sleeper, European perch, zander, wels catfish and the common yabby as “injurious wildlife” under the Lacey Act.

Fate of turtles and tortoises affected more by habitat than temperature
Environmental News Network – September 27, 2016
Habitat degradation poses a greater risk to the survival of turtles and tortoises than rising global temperatures, according to new research. More than 60 percent of the group are listed by the International Union for Conservation of Nature (IUCN) as vulnerable, endangered, or critically endangered, because they are being traded, collected for food and medicine and their habitats are being degraded. Understanding the additional impact of global warming and changes in rainfall patterns on their diversity and distributions is therefore paramount to their conservation. For full story, click here.
What the Ancient Oyster Knows
By Geoffrey Giller – Hakai Magazine – September 13, 2016
Stephen Durham ignores the cold water seeping into his hiking boots as he wades into a shallow, brackish creek wending through a salt marsh in Madison, Connecticut. With each step, shells crunch under his feet and he sentences a few more oysters to an early death. Below these casualties, the remains of their ancestors lie entombed in the muck. Less than a meter down, they could be hundreds of years old—artifacts of a time before modern record-keeping. Like thousands of soap-dish-sized Rosetta stones, the shells can reveal clues about the past—if you know what you’re looking for. Durham, sporting a trimmed grad-student beard and a hat from a seafood restaurant, is a new kind of sleuth. He’s one of the world’s first students trained in conservation paleobiology, a young field that applies a paleontologist’s skill set to modern-day conservation challenges by decoding animal and plant remains.

The challenge makes turning bitumen into oil seem like the easy part. Faced with reclaiming open-pit mines that were once thriving wetlands, Suncor and Syncrude have been trying to do what's never been done — rebuilding one of the most complex, diverse and delicate ecosystems in the boreal forest. Three years into the ground-breaking, high-profile projects, early successes are emerging. Suncor's Nikanotee fen and Syncrude's Sandhills fen are staying wet year-round. They're growing some typical fen plants. Even better, they've begun to store carbon in their peaty depths. For full story, click here.

At the World Conservation Congress, which meets in Honolulu this week, environmental leaders are considering an unusual solution to help endangered animals: planned extinction. Gene drive, a controversial genetic editing technique through which scientists could alter or eliminate entire species, is mostly discussed alongside Zika and malaria fears. But recently, some conservationists have reframed the technique as a way to control invasive species. By slipping genetic disadvantages into the non-native population, they could theoretically protect endemic species. For full story, click here.

Duck numbers increasing
Ducks Unlimited – The Southern Illoisan – August 25, 2016
The U.S. Fish and Wildlife Service released its 2016 Trends in Duck Breeding Populations, based on surveys conducted in May and early June by FWS and the Canadian Wildlife Service. Overall duck numbers in the survey area are statistically similar to last year. Total populations were estimated at 48.4 million breeding ducks, which is 38 percent above the 1955-2015 long-term average. Last year's estimate was 49.5 million birds. The projected mallard fall flight index is 13.5 million birds, similar to the 2015 estimate of 13.8 million. The main factor for duck breeding success is wetland and upland habitat conditions in the key breeding landscapes of the prairies and the boreal forest. For full story, click here.
Science in the Wild: The Legacy Of the U.S. National Park System
By Jim Robbins – Environment360 – August 24, 2016
In a small cabin that serves as the Glacier National Park climate change office, Dan Fagre clicks through photos that clearly show the massive glaciers that give this park its name are in a hasty retreat. "There was a hundred square kilometers of ice in 1850," Fagre, a United States Geological Survey researcher who has studied the glaciers of Glacier since 1991, explains. "We are down to 14 to 15 square kilometers, so an 85 to 86 percent loss of ice in the park. There's no doubt they are going to disappear unless some massive cooling happens," he says, which isn't likely. The flows of mountain streams and rivers throughout the park will dwindle as their sources melt. And one species that will dearly miss the ice-cold runoff from the glaciers is the meltwater stonefly, an insect that's only found in a few glacier-fed streams in the park. It will likely disappear when the glaciers vanish, the U.S. Fish and Wildlife Service says. For full story, click here.
Lichen is a famous biological partnership — but it might actually be a threesome
By Rachel Feltman – The Washington Post – July 22, 2016
Traditionally, scientists have likened lichen to a married couple: The crusty growths found on trees and rocks are actually composite organisms, formed by the symbiotic partnership between an algae and a single fungus. But a new study throws a wrench into that 150-year-old belief, suggesting that a third partner has been lurking in the mix. A second fungus — this one a type of yeast — makes the synergy possible.

How purple bacteria could help save amphibians in the Rockies
By Krista Langlois – High Country News – August 1, 2016
Browns Creek slips out of the Collegiate Peaks near the central Colorado towns of Salida and Buena Vista. Bordered by conifer forests and alpine wetlands, the waterway offers perfect habitat for an obscure amphibian called the boreal toad, a warty, mottled creature about the size of a human palm. Historically, boreal toads abounded in Rocky Mountain streams above 7,000 feet, but in the past several decades, populations have plummeted. For full story, click here.
New Study Quantifies Benefits of Agricultural Conservation in Upper Mississippi River Basin
Contacts: Alex Demas and Sarah Haymaker, USGS – Soil Erosion News Today – June 22, 2016
Researchers at the U.S. Geological Survey and the U.S. Department of Agriculture have published a new studyThis is an external link or third-party site outside of the United States Department of Agriculture (USDA) website. that demonstrates that agricultural conservation practices in the upper Mississippi River watershed can reduce nitrogen inputs to area streams and rivers by as much as 34 percent. The study combined USDA's Conservation Effects Assessment Project (CEAP) data with the USGS SPARROW watershed model to measure the potential effects of voluntary conservation practices, which historically have been difficult to do in large river systems, because different nutrient sources can have overlapping influences on downstream water quality.

Threats to habitat connectivity as sea waters inundate coastal areas
By Jim Melvin, Clemson University – Environmental News Network – June 21, 2016
By the year 2100, sea levels might rise as much as 2.5 meters above their current levels, which would seriously threaten coastal cities and other low-lying areas. In turn, this would force animals to migrate farther inland in search of higher ground. But accelerated urbanization, such as the rapidly expanding Piedmont area that stretches from Atlanta to eastern North Carolina, could cut off their escape routes and create climate-induced extinctions.

On the Bay: Chesapeake's no oxygen 'dead zone' to be average or smaller
By Christina Jedra – Capital Gazette – June 14, 2016
Scientists estimate this year's Chesapeake Bay low-oxygen "dead zone" will be roughly the volume of 2.3 million Olympic-size swimming pools —about average. The National Oceanic and Atmospheric Administration announced Monday that the hypoxic, or low-oxygen, zone will be approximately 1.58 cubic miles, close to the long-term average since 1950. "The low oxygen levels are insufficient to support most marine life and habitats in near-bottom waters and threaten the Bay's production of crabs, oysters and other fisheries," NOAA said.

Researchers at the Virginia Institute of Marine Science are studying sea turtle mortality in an effort to protect living turtles from harm by releasing "Frankenturtles" into the Chesapeake Bay. Assistant Professor David Kaplan and graduate student Bianca Santos are trying to pinpoint where hundreds of dead loggerhead sea turtles that wash up on beaches of the Chesapeake Bay every year may have died. They hope that information will help them figure out likely causes of sea turtle death and help map out "safe zones" for the turtles. For full story and to view video, click here.
Can Native American Oyster Practices Rejuvenate the Chesapeake Bay?
By Kastalia Medrano – Pacific Standard Magazine – June 16, 2016
Estuary systems are in decline around the world. Polluted waters, overfishing, and sea levels rising as a result of climate change have left many marine ecosystems a mess. And the Chesapeake Bay, after a century of overfishing and deteriorating water quality, is in trouble. In the ongoing search for ways to restore the Chesapeake, an interdisciplinary team of scientists from the Smithsonian Institution — including biologists, resource managers, archaeologists, anthropologists, even a paleontologist — may have found the key in one of the watershed’s most vital and iconic symbols: the oyster.

The Drought Solution That's Under Our Feet
By Padma Nagappan – News Deeply – June 6, 2016
Now in the fifth year of an epic drought, Californians have explored ways to save water and wring it out of typical and atypical sources. The search has spanned the gamut from funding research, investing in expensive solutions like desalination plants, toying with the idea of recycling wastewater, imposing water-use restrictions, letting lawns go dry and experimenting with irrigation efficiency techniques for the crops that feed the country. Thirsty crops, a burgeoning population and below-average precipitation have also led to seriously overdrawn groundwater sources that took a very long time to fill up. The state’s agricultural industry, which grows more than 250 crops, has also been vilified for its heavy water use. But is the Golden State missing a solution that could offer a high payout – a solution that’s right under its feet? For full story, click here.
America’s Sickest Wetlands Are in the West, EPA Finds
By John Upton – Climate Central – May 31, 20 16
Few people will see the marshland that Beth Moseley helps spruce up during her volunteer outings to an industrial stretch of bayfront. Its hidden solitude from San Francisco’s hustle and bustle is one of the reasons she often visits the restored wetland to watch birds. “Most of the work we do is pulling weeds,” said Moseley, a 61-year-old resident of the city’s Mission district, who has been joining the Audubon Society’s monthly work days at the Pier 94 wetland for several years. “It’s kind of like the bay is taking care of itself.” The fruitful growth of the salt marsh over the last decade offers a germ of briny hope in a region where wetlands have been paved, diked and invaded by weeds at a rate unmatched elsewhere in the U.S. An exhaustive assessment released by the EPA this month based on more than 1,000 wetland surveys conducted in 2011 concluded that while nearly half of the remaining wetlands in the Lower 48 are in “good” condition, just one-fifth of the wetlands in the West are doing that well.

EPA: Western wetlands in poor condition
By Will Houston – Times Standard News – May 20, 2016
A first-of-its-kind report card on the nation’s wetland habitats shows the western U.S. is not doing a good job at keeping these disappearing ecosystems in good condition. The report, released by the U.S. Environmental Protection Agency this month, found only 21 percent of the 146 surveyed wetlands west of the Rocky Mountains were in “good” condition compared to about 61 percent in poor condition and 18 percent in fair condition. Common impairments for these western wetlands and those throughout the nation are ditches and draining systems, nonnative plants, loss of native plants, and surface hardening such as road paving and other development — all of which have occurred in Humboldt County, according to Humboldt Baykeeper Director Jennifer Kalt. “The public lands wetlands are being treated much better than they used to be and the private land wetlands are continuing to be abused and destroyed,” she said.

Saving Amphibians: The Quest To Protect Threatened Species
By Jim Robbins – environment360 – May 12, 2016
In the mountains of western Washington, Oregon, and northern California, the Cascades frog lives most of its life cycle buried beneath deep, wet snow. When summer rolls around, though, it emerges into alpine wetlands to mate and emit its signature call, which sounds a lot like a person chuckling. The habitat of these chuckling frogs, though, and other amphibians, is being squeezed by what researchers call a climate vise. Receding glaciers here left the mountains pockmarked with thousands of lakes and ponds, some the size of a car and some acres in size. Originally fishless, 19th and 20th century managers introduced fish to 95 percent of the lakes, carrying them in on horseback or dropping them from airplanes. It seemed like a good idea at the time. But the invasive trout have hammered the frog and salamander populations: They not only gobble up the tadpoles and juveniles, they limit the production of invertebrates, essential amphibian food. Amphibians can often escape the fish-filled ponds for nearby fishless wetlands, but as temperatures warm and snowpack shrinks, these survival outlets are waning and disappearing.

Milliron Wetlands classroom dedicated by OSU-Mansfield
By Zack Lemon – Mansfield News Journal – April 18, 2016
It was in the early 1960's when Grant Milliron was approached with an offer to fund one acre of the Ohio State campus that was to be built. He was asked for $100, which he pulled out of his pocket, and handed over immediately. "That is probably one of the best investments I've ever made," Milliron said at the dedication of the wetlands and outdoor classroom he donated to the university. "I'm not sure which acre of the 600 I got, but it doesn't make any difference." The Grant and Mary Milliron Research Wetlands and Classroom was a roughly $150,000 project, according to planner and project manager Brian White. It was completed last summer after two-and-a-half months of construction. For full article, click here.
The Fate of Sediment When Freshwater Meets Saltwater
Contacts: Greg Noe and Jon Campbell – U.S. Geological Survey – February 17, 2016
Two recent USGS investigations have measured sedimentation rates along the barely perceptible slope of rivers as they empty into estuaries. The findings of these studies have important implications for the restoration of estuaries — for example, the Chesapeake Bay — and their resilience in the face of sea level rise. The studies compared the sedimentation rates found in upriver tidal freshwater swamps (located at the furthest inland reach of tides) to the rate found in brackish water marshes downstream at the lowest reaches of the rivers.

Road salt putting human, aquatic lives on a collision course
By Karl Blankenship – Bay Journal – March 3, 2016
Just a couple days before January’s “snowzilla” storm buried much of the region under 2 feet of snow, District of Columbia Mayor Muriel Bowser apologized for the city’s “inadequate response” to less than an inch of snow that left motorists variously sliding though icy streets or stranded in backups. Since 1938, when New Hampshire began experimentally salting winter roads, the substance has increasingly become an effective — and cost-effective — way to combat the slippery effects of ice and snow. Nationwide, 10 times as much salt goes on the road as is used to season all processed foods. But as with food, too much salt in freshwater is harmful. It’s a growing problem that threatens efforts to protect stream health in the Chesapeake watershed, and even in the Bay itself. For full article, click here.

Migratory fish have more rivers in the Bay to swim, and underwater grass beds are growing, but streamside forest plantings and wetland restoration have lagged badly in recent years, a new report from the state-federal Chesapeake Bay Program shows. It's Bay Barometer, an annual assessment of the Chesapeake region’s pollution reduction and habitat restoration efforts, found uneven progress toward meeting the 11 goals set in the Bay Watershed Agreement adopted in 2014. While much of the information has already been publicly released, the report compiles it to offer an overview of restoration efforts. For full article, click here.
Wetlands conservation milestone for WWF
World Wildlife Fund – February 1, 2016
The designation of wetlands for conservation with WWF support reached over 100 million hectares worldwide with the declaration of seven sites in Zimbabwe under the Ramsar convention. The news comes just ahead of World Wetlands Day on 2 February and following the identification of water crises as one of the top three global risks, according to the World Economic Forum’s Global Risk Report 2016. With this year’s World Wetlands Day focusing on wetlands and livelihoods, a number of sites such as Lake Chivero, the primary water supply for Zimbabwe’s capital city Harare, are of particular significance. “When we mark World Wetlands Day, we are reminding people that water doesn’t come from a tap; it comes from healthy wetland ecosystems,” said Lifeng Li, WWF International’s Director of Freshwater.

EPA Releases Scientific Report Showing U.S. Coastal Waters a Mix of Good and Fair Health
Contact: Robert Daguillard – EPA-Yosemite – January 28, 2016
The U.S. Environmental Protection Agency (EPA) today released the 2010 National Coastal Condition Assessment showing that more than half of the nation's coastal and Great Lakes nearshore waters are rated good for biological and sediment quality, while about one-third are rated good for water quality. In almost all coastal waters, however, contaminants in fish tissue pose a threat to sensitive predator fish, birds, and wildlife. The National Coastal Condition Assessment is part of a series of National Aquatic Resource Surveys (NARS) designed to advance the science of coastal monitoring and answer critical questions about the condition of waters in the United States.

Grass-planting change boosts coastal wetland restoration success
Ecology Global Network – November 13, 2015
When restoring coastal wetlands, common practice calls for leaving space between new plants to prevent overcrowding and reduce competition for nutrients and sunlight. That’s likely all wrong. A new study, conducted to restore degraded salt marshes in Florida and the Netherlands, has found that clumping newly planted marsh grasses next to each other, with little or no space in between, can spur positive interactions between the plants. In some test plots, plant density and vegetative cover increased by as much as 300 percent by season’s end. For full story, click here.

Environment group warns against reducing manatees' endangered status
By Oliver Milman – The Guardian – January 12, 2016
A US government move to downgrade the conservation status of manatees and green sea turtles is premature, an environment group has warned, despite encouraging signs that both species are recovering. The US Fish and Wildlife Service (FWS) has proposed that the West Indian manatee be down-listed from endangered to threatened under the endangered species act. The move follows a notable recovery in manatee numbers – in 1991, it was estimated there were just 1,267 of the hefty aquatic beasts off the coast of Florida. That number has now swelled to 6,300 in Florida, with 13,000 in total across the manatee’s entire range, which stretches throughout the south-eastern US, Caribbean, Mexico and the northern coasts of South America. The FWS said that work to reduce collisions with speedboats and unintentional entanglements with fishing nets has paid off, as well as the effective rehabilitation of sick and injured manatees, which can weigh over 3,000 pounds and are nicknamed “sea cows” because they eat copious amounts of sea grass.

Leaving it to beavers: Communities make room for natural engineers
By Whitney Pipkin – Bay Journal – December 14, 2015
Once valued as little more than pelts, beavers are back in vogue and rebuilding their reputation as habitat engineers. It helps their cause that the dams they build as homes also create water quality-boosting wetlands and habitat for other species. In the process, the structures slow the flow of water and filter out sediment that would otherwise be on its way to the Chesapeake Bay. And a new study out of the Northeast suggests the dams, which can alter the course of entire river systems, can also substantially reduce the amount of nitrogen in them. For full story, click here.

Piping plovers, a federally threatened species of shorebirds, are likely losing wetland breeding habitat in the Great Plains as a result of wetland drainage, climate change or both, according to a new U.S. Geological Survey study. “Our findings suggest that if drainage continues, there will be continued declines in the amount of breeding habitat for piping plovers at wetlands in the Great Plains,” said Lisa McCauley, who led the study as a USGS postdoctoral student and currently works at The Nature Conservancy. “Managers can use information from our study to better restore and conserve valuable wetland ecosystems for the protection of this species.” For full story, click here.
New map of Earth's groundwater to help estimate when it may run out
By Magda Mis –Thomson Reuters Foundation – November 16, 2015
The first map showing the world's hidden groundwater was published on Monday, bringing us closer to estimating how much there is, and when it will run out if we over-use the resource. Using data and computer models, an international team of researchers estimated that less than six percent and perhaps as little as one percent of water found close to the Earth's surface is renewable in a human lifetime. "This has never been known before," Tom Gleeson of Canada's University of Victoria and the lead author of the study, said in a statement. "We already know that water levels in lots of aquifers are dropping. We're using our groundwater resources too fast - faster than they're being renewed." For full story, click here.

U.S. Rivers Show Few Signs of Improvement from Historic Nitrate Increases
USGS – October 28, 2015
During 1945 to 1980, nitrate levels in large U.S. Rivers increased up to fivefold in intensively managed agricultural areas of the Midwest, according to a new U.S. Geological Survey study. In recent decades, nitrate changes have been smaller and levels have remained high in most of the rivers studied. The greatest increases in river nitrate levels coincided with increased nitrogen inputs from livestock and agricultural fertilizer, which grew rapidly from 1945 to 1980. In some urbanized areas along the East and West coasts during the same period, river nitrate levels doubled. Since 1980, nitrate changes have been smaller as the increase in fertilizer use has slowed in the Midwest and large amounts of farmland have been converted to forest or urban land along the East coast.

San Francisco Bay: Race to build wetlands is needed to stave off sea-level rise, scientists say
By Paul Rogers – San Jose Mercury News – October 18, 2015
San Francisco Bay is in a race against time, with billions of dollars of highways, airports, homes and office buildings at risk from rising seas, surging tides and extreme storms driven by climate change. And to knock down the waves and reduce flooding, 54,000 acres of wetlands -- an area twice the size of the city of San Francisco -- need to be restored around the bay in the next 15 years. That's the conclusion of a new report from more than 100 Bay Area scientists and 17 government agencies that may help fuel a regional tax measure aimed at addressing the looming crisis.

Sonoma County restoration project aims to make 1,000 acres of farmland a tidal marsh basin over the next 25 years. The Santa Rosa Press Democrat reports that supporters and partners of the Sonoma Land Trust gathered Sunday to watch an excavator break through a Sears Point levee, allowing saltwater to flood over the reclaimed oat fields. Officials say it will take decades for the marshland's vegetation and wildlife to return. For full story, click here.
Scientists play catch up as new chemicals contaminate Great Lakes birds
By Brian Bienkowski – Environment Health News – October 6, 2015
Stain repellent and fire retardant chemicals that scientists know little about are increasingly showing up in herring gull eggs around the Great Lakes, spurring concern for potential health impacts. The gulls are considered a sentinel species, and the contaminants appearing in their eggs paint a picture of a shifting chemical profile in the Great Lakes, which holds about 20 percent of the world’s fresh surface water. While legacy pollutants, such as mercury and polychlorinated biphenyls (PCBs), still persist, a growing list of esoteric pollutants is showing up in wildlife. For full story, click here.
Healthy Soils Reduce Water Pollution
By Brett Walton – Circle of Blue – October 13, 2015
On a bright October morning in a hotel parking lot, Greg Scott turns on the rainfall simulator. The machine’s swiveling nozzle sprays fat drops on five soil samples held in trays a few feet below. Some soil is bare; other samples are planted with prairie grass, wheat, and other field crops. Within minutes dirty, sediment-saturated water begins flowing off the plots that are not anchored by vegetation. In the other trays, the drops soak into the ground. The little water that does run off the planted trays is much cleaner, the color of green tea. The lesson of the artificial cloudburst is clear: neglect the soil and water will suffer.

Scientists say a dramatic worldwide coral bleaching event is now underway
By Chris Mooney – The Washington Post – October 8, 2015
For just the third time on record, scientists say they are now watching the unfolding of a massive worldwide coral bleaching event, spanning the globe from Hawaii to the Indian Ocean. And they fear that thanks to warm sea temperatures, the ultimate result could be the loss of more than 12,000 square kilometers, or over 4,500 square miles, of coral this year — with particularly strong impacts in Hawaii and other U.S. tropical regions, and potentially continuing into 2016.

Pilot Project Tests Wetland vs. Nitrates
By Donnelle Eller – The Des Moines Register – September 13, 2015
About 1,000 acres of rich northwest farmland drain into a 10-acre wetland, where grasses, cattails and other vegetation help hardworking microbes remove nitrates from the water before they can enter the Des Moines River. The pilot project, one of five wetlands constructed at the same time the drainage systems were rebuilt, works to offset nitrate losses from the tile it connects with. With an aging tiling network that drains 12 million acres, the state faces a unique opportunity to construct the conservation practices needed to dramatically improve Iowa’s water quality, says Sean McMahon, executive director of the Iowa Agriculture Water Alliance.

Male Frogs May Be Turning Female Thanks to Estrogen in Suburban Waste
By Douglas Main – Newsweek – September 7, 2015
A surprising study has found that frogs in suburban lakes tend to be mostly female, and suggests that urbanization and estrogenic wastes are likely turning male frogs female. In a study published September 7 in the journal Proceedings of the National Academy of Sciences, researchers sampled hundreds of young frogs from 21 ponds in Connecticut, which were all geographically close but varied widely in terms of how developed their immediate surroundings were. The scientists, led by Yale University researcher David Skelly and doctoral student Max Lambert, were surprised to find that the extent of development was strongly linked to the proportion of females; ponds in forests contained lower proportions of females, whereas males were in the minority in some areas of the ‘burbs.
