Interview: Can Marine Life Adapt
To the World’s Acidifying Oceans?
As the world’s oceans grow more acidic from increased absorption of atmospheric carbon dioxide, marine scientists are confronting a key question: How well can
organisms like mollusks, crustaceans, and corals adapt to these more corrosive conditions? One of the leading authorities in this field is University of California, Santa Barbara marine biologist Gretchen Hofmann. Her work in recent years has shown, in fact, that some sea organisms that build shells do seem to have some ability to acclimate to more acidic waters. But in an interview with Yale Environment 360
, Hofmann cautions that this adaptive capacity has its limits. The continuing burning of fossil fuels, she says, could push ocean acidity past a tipping point, rendering some mollusks and other organisms unable to build shells.

Biodiversity, But Not Community
Composition, Surprisingly Stable Over Time
A major turnover of species in habitats around the globe is underway, resulting in the creation of novel biological communities, but overall species diversity is much more
stable than scientists had believed, according to a new report
in the journal Science
. In a survey of 100 long-term biodiversity monitoring projects in a variety of habitats around the world, the authors found that the majority of those studies (59 percent) documented increasing species richness. Biodiversity declined in 41 percent of the studies, but, in all cases the overall change in biodiversity was modest, the researchers said. When looking at changes in the species constituting those communities, however, the researchers found a surprisingly high rate of change — an average of about 10 percent change per decade. "A main policy application of this work is that we're going to need to focus as much on the identity of species as on the number of species," one of the study's authors said. "The number of species in a place may not be our best scorecard for environmental change."

Darwin's Finches Fight Off
Parasitic Maggots with Treated Nest Fibers
Researchers apparently have discovered a unique way to help Darwin's finches on the Galápagos Islands fight off the parasitic maggots
threatening their survival, according to a new report
in the journal Current Biology
. While working in the Galápagos, scientists
A Darwin's finch collects treated cotton for its nest
from the University of Utah noticed that the finches often collected cotton and other fibers to weave into their nests. The researchers decided to provide the birds with cotton treated with permethrin — a mild pesticide, commonly used to treat head lice in children, that is safe for birds — hoping the finches would incorporate the fibers in their nests. Finches near the test sites did just that, and their "self-fumigated" nests contained about half as many parasitic maggots — which infest and can kill newly-hatched chicks — compared to nests with untreated cotton. Darwin's finches and other bird species in the Galápagos have suffered steep population declines since the flies showed up in large numbers in the 1990s.
Carries on in Key Arctic Ecosystem
At a time of rapidly deteriorating relations between Russia and America, U.S. scientist Joel Berger continues his work with his Russian counterparts
Third in a series of blog posts from the Russian Arctic
on Siberia's Wrangel Island. In the third of three blog posts for Yale Environment 360
, Berger — a biologist with the Wildlife Conservation Society and the University of Montana — writes about efforts to better understand how rapid climate change might affect muskoxen and other wildlife in the Russian and North American Arctic. As Berger explains, a key focus of Russian-American scientific cooperation is Beringia, the region of northwestern Alaska and extreme northeastern Russia where two countries — and continents — are divided by the Bering Sea.

Browning of Congo Rainforest
Is Depicted in NASA Satellite Data
Persistent drought has taken a major toll on Africa's Congo rainforest, with large-scale browning intensifying and affecting a growing portion of the forest over the past decade, an analysis of NASA satellite data shows
browning trend significantly dwarfed smaller areas of "greening" — a satellite-derived indicator of forest health — during April, May, and June each year from 2000 to 2012, according to research published in Nature
. The browning of Congo's rainforest is significant, researchers said, because most climate models forecast that tropical forests may face increasing stress and rainfall shortages in a warmer and drier 21st century. A continued drying trend might alter the composition and structure of the Congo rainforest, affecting its biodiversity and carbon storage, according to the study. "Recent climate anomalies as a result of climate change and warming of the Atlantic Ocean have created severe droughts in the tropics, causing major impacts on forests," a NASA researcher said.

Scale and Extent of Dam Boom
In China Is Detailed in Mapping Project
China is planning to build at least 84 major dams in its southwest region, as shown in a map from the Wilson Center, eventually boosting its hydropower capacity by more than 160 gigawatts. By next year China's capacity
will surpass Europe's, and by 2020 it's projected to be larger than that of the U.S. and Europe combined. An interactive map
shows the scale and number of major dams proposed, under construction, existing, and canceled. The dam rush is part of an ongoing effort by China to increase non-fossil energy sources to 11.4 percent of the country's total energy consumption — a goal that has gained urgency due to severe air pollution in many northern Chinese cities. However, the hydropower push is not without its own major environmental consequences
, the Wilson Center notes. The cascades of planned dams will submerge important corridors connecting tropical rainforests to the Tibetan Plateau that allow wildlife to migrate as temperatures rise.

Parasitic Flatworm Could Be
Major Threat to Coral Reefs, Scientists Say
A coral-eating flatworm with a unique camouflaging strategy could be a major threat to the world's coral reefs, according to
researchers in the U.K. The parasite, called Amakusaplana acroporae
, infects a type of staghorn coral known as acropora, a major component
Amakusaplana acroporae, a parasitic coral flatworm
of reefs, and can destroy its coral host very quickly. The parasite has been detected at the Great Barrier Reef, and because it has no known natural predators, researchers are concerned it could spread quickly and decimate reefs worldwide. A novel camouflaging strategy makes the flatworm difficult to detect and monitor, the researchers say. When eating the coral tissue, the worm also ingests the coral's symbiotic algae. Instead of digesting the algae completely, the worm keeps a fraction of them alive and distributes them, along with the fluorescent pigments that give coral its characteristic hue, throughout its gut so that it perfectly mimics the appearance of the coral. The parasite has been identified in numerous aquarium-based corals, and biologists worry that it could spread rapidly if aquarium-raised coral, fish, or seaweed are introduced to natural reef environments.

'Living Fences' Dramatically
Cut Livestock and Lion Killings in Tanzania

attacks and retaliatory killings by more than 85 percent in the areas they've been installed, the Guardian reports
. Traditionally, the Masai have built livestock enclosures out of thorny acacia trees, but those fences are relatively fragile. Chain-link fencing alone is more durable, but leopards and small lions can scale the fences, and hyenas can tunnel in below. By interweaving actively growing African myrrh trees with the chain link fencing, the Masai have created a barrier that lions can't climb over, and their root systems prevent predators from digging under the fence. Because livestock predation has been cut, communities that had been killing six or seven lions annually now kill, on average, less than one, leading to a rebound in lion populations.

Deforestation of Sandy Soils
Increases the Release of CO2, Study Finds
The texture of the soil that microbes live in determines how much carbon they release after deforestation, with sandy soils sending the most carbon into the atmosphere, according to research
led by Yale scientists.
Soils most affected by forest loss in red; least in yellow.
Subterranean microbes regulate carbon emissions from soil, and drastic changes to the microbial community, such as those that follow deforestation, can allow more CO2 to escape into the atmosphere and exacerbate global warming. The texture of soil, rather than such factors as temperature or nutrient concentrations, was the most important factor governing the release of CO2, the researchers found. Muddy, clay-like soils provide the most stable environment for microbial communities, likely because they're better at retaining nutrients than loose, sandy soils. The team used the findings to map areas in the U.S. where soil microbial communities would be most and least affected by deforestation, which could help inform land management practices.

Wildflower Season in Rockies
Is 35 Days Longer as Climate Warms
A warming climate has extended the wildflower season in the Rocky Mountains by 35 days since the 1970s,
according to a 39-year study of more than two million blooms. The bloom season, which used to run from late May to early September, now lasts from late April to late
Crested Butte, Colorado
September, the researchers say. Previous, less extensive studies seemed to indicate most wildflowers simply shift their bloom cycles to earlier in the year, but new findings
published in the Proceedings of the National Academy of Sciences
show that the changes are more complex, with the flowers reaching peak bloom sooner and flowering later in the year. The shift in the timing of blooms could have a major impact on pollinating insects and migratory birds. For example, hummingbirds that summer in the Rocky Mountains time their nesting so that their eggs hatch at peak bloom, when there is plenty of flower nectar for hungry chicks. As the bloom season lengthens, the plants are not producing more flowers. The same number of blooms is spread out over more days, so at peak bloom there may be fewer flowers and less food for hummingbirds, the researchers say.

Routes of Young Sea Turtles
Shed Light on Mystery of Turtles' Lost Years
By placing satellite tags on newborn sea turtles along the coast of Florida and tracking them in the western Atlantic Ocean, researchers have gained new insights
into the early migrations of threatened and endangered
turtles during their so-called "lost years" between hatching and returning to coastal waters as large juveniles. Rather than swimming in the currents of the North Atlantic gyre, as scientists had assumed, the young turtles actually leave the gyre and travel to the Sargasso Sea, which lies in the middle of the North Atlantic Ocean. While there, sensors on the turtles' shells registered more heat than the scientists expected, leading them to believe
that the young turtles swim near the surface of the Sargasso, basking in sunlight and feeding on a type of seaweed that grows in deep ocean waters. "From the time they leave our shores, we don't hear anything about them until they surface near the Canary Islands, which is like their primary school years," said an author of the study.

Seafaring Drones Could Reveal
Mysterious Lives of Sharks, Researchers Say
New automated watercraft
are helping scientists understand the secret lives of great white sharks, which gather in large numbers each winter in an area nicknamed the "White Shark Cafe." Although this stretch of ocean between Baja California and Hawaii
contains relatively few food sources, the sharks congregate and display strange behaviors, perhaps related to mating or feeding, one researcher explained to the San Francisco Chronicle
. Scientists haven't had a way to efficiently track and observe sharks in this environment, but new seafaring drone technologies might change that. For example, drones could follow migrations by homing in on acoustic tags on the sharks themselves. Marine biologists at Stanford
were recently able to track two great whites on their journeys from California to Hawaii and the White Shark Cafe, as the map shows, but current technology only allows scientists to recreate the sharks' journeys after monitoring tags pop off and are recovered. The new drones may prove useful not only for tracking sharks and other pelagic fish in real time, but also for collecting important ocean data such as temperature, acidity, and salinity, researchers said.

Website Allows Whistleblowers
To Report Wildlife and Forest Crimes
A new whistleblower site
offers people a secure and anonymous way to report incidents of poaching, wildlife trafficking, and illegal logging around the world. The site is called WildLeaks, a nod to the well-known WikiLeaks site, and it's backed by the California-based Elephant Action League. Users can upload documents, video, or images detailing the crimes, and submissions will be encrypted so data and identities remain secure. The aim
is to provide a safe way for citizens to report these illegal activities so that local and federal governments can take action. Prosecuting wildlife crimes and illegal logging is often a low priority in countries where some of the worst offenses occur; moreover, local government corruption often deters people from reporting such crimes, organizers say. "We [will] work to transform this information into a verified and actionable item, a point for launching an investigation or sharing it with the media or, when possible, with selected and trusted law enforcement officers, always aiming at exposing wildlife crimes and bringing the responsible individuals to justice," said the WildLeaks project leader.

New Maps Pinpointing Wind
Turbines Will Help Track Effects on Wildlife
More than 47,000 wind turbines dot the U.S. landscape, predominantly clustered in the Midwest and Great Plains, as a new interactive tool
developed by the U.S. Geological Survey (USGS) shows. The maps — the first
publicly-available, nationwide data set for wind energy generation — show the locations of every turbine in the U.S., from large wind farms to single turbines, and are accurate to within 10 meters. The maps are part of the USGS's effort to assess how wind turbines impact wildlife, and they show detailed technical information such as the make, model, height, area of the turbine blades, and capacity of each turbine. Turbine-level data will improve scientists’ ability to study wildlife collisions, the wakes causes by wind turbines, the interaction between wind turbines and ground-based radar, and how wind energy facilities overlap with migratory flyways, the USGS says.

New Plant Found in Andes
Supports up to 50 Species, Researchers Say
Researchers working in the Ecuadorian Andes have discovered a new species of black pepper plant
that is a nexus of biodiversity. The plant, named Piper kelleyi
, supports roughly 40 to 50 insect species, the scientists estimate, many of which are entirely dependent on the
Specialist herbivore Eios feeds on P. kelleyi
plant for survival. P. kelleyi
produces chemical compounds that are known to deter most herbivores, but a single type of caterpillar has adapted to overcome the toxicity of the plant's defenses. That caterpillar, in turn, is preyed upon by species of wasps and flies dependent on that specific caterpillar species — and ultimately the plant — for survival. Altogether, an assemblage of up to 50 species of herbivorous and predatory insects are dependent on P. kelleyi
, the researchers report in the journal PhytoKeys

Documented in Remote Forest in Congo

forest, is thought to be the largest population of chimps in Africa and one of the last remaining continuous populations of chimpanzees in the wild, the scientists report
in the journal Biological Conservation
. The researchers first reported on this community in 2007, but their new survey includes detailed videos of the thriving population and its unique behaviors, which include feasting on leopards, using tools to harvest giant African snails and swarming insects, and building ground nests far more frequently than other chimps. While the find is heartening in terms of chimpanzee conservation, the researchers and wildlife advocates fear the population could be decimated by habitat loss and poachers, who stand to make huge profits in the bushmeat trade.

Maps Show Tropical Corridors
Important to Wildlife As Climate Changes
A new set of maps
highlights the importance of habitat corridors in helping wildlife deal with the effects of climate change and deforestation. The series of maps shows more than 16,000 habitat corridors
— swaths of
land that connect forests or protected areas and allow animals to move between them — in tropical regions of Africa, Southeast Asia, and South America. High-resolution data on biodiversity, endemism, and vegetation density allowed the researchers, led by Patrick Jantz of the Woods Hole Research Center, to determine which corridors are most important for maintaining biodiversity under changing climate conditions. The maps also highlight which corridors are most important for sequestering carbon and averting carbon emissions associated with deforestation. Researchers hope the findings will help guide wildlife protection plans and serve as a framework prioritizing the conservation of habitat corridors.

Peru Park Holds Record
Reptile and Amphibian Diversity, Study Finds
A new study crowns Peru's Manu National Park
as the place with the world's most diverse collection of reptiles and amphibians — 287 species in all. The park's 155 amphibian and 132 reptile species outnumber those in Ecuador's Yasuní National Park
, which, with 271 reptile
A glass frog from Manu's cloud forests
and amphibian species, was previously believed to contain the world's most diverse collection of reptiles and amphibians. Although Manu National Park represents only 0.01 percent of the world's land area, it houses 2.2 percent of all amphibian species and 1.5 percent of all reptile species, the researchers note. They attribute the rich diversity to the park's elevation gradient, which spans the Western Amazon's tropical rainforest up through high Andean cloud forests, providing a wide range of habitats. Manu also has record bird diversity — with 1,000 species, or 10 percent of the world's total species — and tremendous butterfly diversity, with 1,200 species. Scientists say the inventory of the national park's richness is far from complete. DNA analyses, frog call studies, and other techniques will likely reveal even more diversity, the authors note in the journal Biota Neotropica
Interview: How Citizen Science Is
Aiding and Democratizing Research
When biologist Caren Cooper
carries out her avian studies, she’s aided by thousands of assistants, none of whom are paid for their work. That’s because Cooper, a research associate at the Cornell Lab of Ornithology
, relies on the help of so-called citizen scientists, volunteers from across the country who contribute data
to her research projects. These lay people provide information that enables her and other scientists to study bird life in ways that would otherwise be impossible. But, as Cooper notes in an interview with Yale Environment 360
, the uses of citizen science go well beyond bird research. Bushmen in the Kalahari are using apps to document wildlife and natural resources that need to be protected. Environmental activists also are employing open-source technology to measure and monitor pollution, including the deployment of kites and balloons to document such events as the Deepwater Horizon oil spill. “A lot of the ways for us to move forward in certain fields require massive collaboration,” says Cooper. “And so we’re building all the infrastructure for these collaborations, all of the web tools — whatever we need to make that happen.”

New Virus Associated With
Massive Bee Die-Offs, Researchers Report
A rapidly mutating virus may be partially responsible for the massive bee die-offs known as colony collapse disorder (CCD), which has wiped out a third of commercial bee colonies annually for the past seven years, a group of U.S. and Chinese researchers reports
. Most scientists, including the study's authors, believe CCD is triggered when colonies are weakened by a combination of factors
, such as viruses, parasites, and perhaps pesticides. The study, published
in the journal mBio
, found in bees a variant of the tobacco ringspot virus, an RNA virus that likely jumped from tobacco plants, to soy plants, to bees. Weak bee colonies began succumbing to massive die-offs in autumn, and the researchers found those bees were heavily infected with tobacco ringspot — which is believed to affect honeybees' nervous systems — and other viruses. Strong colonies that made it through the winter showed no evidence of infection by tobacco ringspot. The researchers believe the virus jumped from plants to bees through "bee bread," a concoction of pollen, nectar, and saliva they feed their larvae. Bee infection by tobacco ringspot is the first known instance of a virus from pollen jumping to bees.

Soil Microbes Can Alter DNA
In Response to Climate Change, Study Says
A 10-year study of soil ecosystems
has determined that microbes alter their genetic code in response to a warming climate so they can process excess carbon being absorbed by plants from the atmosphere, a team of U.S. researchers reports in the journal Applied and Environmental Microbiology
. A 2-degree Celsius temperature increase spurred microbes in soil ecosystems to, over many generations, tweak their DNA, amping up their respiratory systems and converting extra organic carbon in the soil to CO2. The soil contained extra carbon because the 2-degree temperature increase made plants grow faster and higher; when those plants began to die, the carbon in their leaves, stems, and roots was added to the soil and taken up by the microbial community. Understanding the "black box" of carbon's fate in soil ecosystems holds important clues for better forecasting an ecosystem's response to climate change, says Georgia Institute of Technology researcher Kostas Konstantinidis, an author of the study. "One reason that models of climate change have such big room for variation is because we don’t understand the microbial activities that control carbon in the soil," he said.

More Than 1,000 Rhinos
Poached in 2013, South African Officials Say
More than 1,000 rhinos were illegally killed in South Africa last year, a record total and an increase of more than 50 percent from 2012, South African officials say
. South Africa is home to nearly all of the
world's 20,000 rhinos, which are targeted by poachers
because their horns are highly valued and believed to contain medicinal properties. Although those claims are scientifically unfounded, demand from increasingly wealthy consumers in China and Vietnam has driven the price of rhino horns to over $65,000 per kilogram — more valuable than gold, platinum, or cocaine. South Africa has tried to stem the crisis by training park rangers to use arms, drones, and helicopters
, but those anti-poaching efforts have shown limited success. Rhino poachings in 2012 also increased by 50 percent over 2011 totals, and 37 have been poached so far in 2014, officials report. Most of the killings are taking place in South Africa's Kruger National Park, where 606 rhinos were killed last year and 425 in 2012.

Pebble Mine Would Endanger
Alaska's Bristol Bay, Major EPA Study Finds
A three-year study by the U.S. Environmental Protection Agency (EPA) has determined that mining in Alaska's Bristol Bay area would pose significant dangers to the environment
, a potentially fatal setback for plans
Mulchatna River, part of Bristol Bay watershed
to develop Pebble Mine, a major open-pit mining project that aimed to exploit one of the largest and richest mineral deposits in the world. The EPA study cited concerns for the region's thriving sockeye salmon population
and its native people, saying the mine would destroy 24 to 94 miles of salmon streams and 1,300 to 5,350 acres of wetlands, ponds, and lakes. Pebble Mine proponents, including Alaska Governor Sean Parnell, criticize the study as flawed and rushed, since the development company wasn't allowed to submit its mining plan before the EPA study. Native groups, fishermen, and environmental organizations are applauding the study. The proposed mine — which seeks to exploit gold, copper, and other metals — was already in trouble, with one of two major partners withdrawing from the project last year.

West African Lions Are
Critically Close to Extinction, Study Says
West African lions are close to extinction, and vulnerable populations could be wiped out in the next five to 10 years, according to new research
led by the wild cat conservation group Panthera. West African lions, which are genetically distinct from other African lions, once numbered in the tens of thousands. Now the
Male West African lion
population has been reduced to around 400 individuals spread across 17 countries, largely due to habitat loss, a shortage of prey, and poaching, according to the study published in PLOS ONE
. Of the remaining lions, only about 250 are mature enough to reproduce, but in many cases those individuals are spread too far apart to breed. West African lions are now present in only 1.1 percent of their original habitat and should be considered "critically endangered," according to the study. Running low on habitat and prey, the lions sometimes kill livestock. Villagers then kill the lions in revenge. "It's become very complicated for this carnivore at the top of the food chain to find enough space and food to survive," one scientist told Reuters.

Faced With Sea Ice Loss,
Emperor Penguins Alter Breeding Tactics
Confronted with the loss of sea ice in some parts of Antarctica, four colonies of emperor penguins have come up with an innovative breeding strategy
to adapt to their changing environment. Using satellite images,
an international team of scientists tracked the four colonies from 2008 to 2012. In the first three years, the emperor penguins hatched and incubated eggs in their customary fashion — atop the sea ice that freezes during the Antarctic winter and spring. But in 2011 and 2012, sea ice did not form until a month after the breeding season began. As a result, the emperor penguins, which are the largest penguin species on earth, did something never before witnessed by scientists: They climbed the nearly sheer walls of large, floating ice shelves — huge structures, often hundreds of square miles in extent, that flow from land-based glaciers into the sea. In the region of the four colonies, the ice shelf walls reach as high as 100 feet. The scientists say the altered breeding behavior could demonstrate how ice-dependent emperor penguins may adapt to a warming world.

China Crushes Six Tons
Of Ivory to Stem Elephant Poaching
In an effort to stem elephant poaching, Chinese authorities have crushed six tons of confiscated ivory
, the first such effort in the country's history. Coordinated by the State Forestry Administration and the General Administration of Customs, the event was widely publicized and aimed at spreading awareness in China of the scale of the global poaching crisis. Conservation
groups consistently name China as a major driver of elephant poaching, as the country's growing middle class has increasingly sought to buy ivory ornaments and ivory-based medicinal therapies, which have no scientific or medical basis. The six tons of ornaments and tusks that were crushed represent only a fraction of China's ivory stockpile, which is probably more than 45 tons, the Wildlife Conservation Society (WCS) estimates. Still, many conservation groups are applauding China's efforts. "This destruction of ivory by China is a symbol of the government's growing responsiveness to the ivory crisis," the WCS said.
