Biologists Still Searching For Answers In Bald Eagle Deaths and other wildlife health news stories

TOP STORIES

Fish-Eating Ducks Hard Hit By Severe Winter, Ice

The Niagara River corridor from Lake Erie to Lake Ontario is renowned as a spectacular winter haven for hundreds of thousands of water birds. But this year's bitterly cold season has made it notable for something else: dead ducks.

Biologists say carcasses began piling up by the hundreds in early January after the plunging temperatures started icing over nearly the entire Great Lakes, preventing the ducks from getting to the minnows that are their main source of food. Necropsies on dozens of birds have confirmed the cause: starvation. "All have empty stomachs. They're half the weight they should be," said Connie Adams, a biologist in the state Department of Environmental Conservation's Buffalo office who has personally seen 950 dead birds.

"This is unprecedented. Biologists who've worked here for 35 years have never seen anything like this," she said. "We've seen a decline in tens of thousands in our weekly waterfowl counts." It's a phenomenon that has been seen elsewhere along the Great Lakes, with news reports of diving ducks and other waterfowl turning up dead by the hundreds along the southern part of Lake Michigan. They've also been found in Lake St. Clair between Lakes Erie and Huron.

... Necropsies and toxicity analyses showed many of the Michigan ducks were subsisting on invasive zebra mussels, which caused the birds to have potentially toxic levels of selenium in their bodies, Mason said. Zebra mussels filter toxins from the water and pass them up the food chain.

Most of the dead ducks seen in the upstate New York are red-breasted mergansers, which breed in northern Canada and Alaska and come south for the winter to the Great Lakes region. In most years, there are periods of freezing and thawing, providing enough breaks in the ice for them to dive for minnows.

Experimental infection of house sparrows (Passer domesticus) with West Nile virus isolates of Euro-Mediterranean and North American origins


...North American WNV outbreaks are often accompanied by high mortality in wild birds, a feature that is uncommon in Europe. The reason for this difference is unknown, but the intrinsic virulence of the viruses circulating in each continent and/or the susceptibility to the disease of Palearctic as opposed to Nearctic wild bird species could play a role.

To assess this question, experimental inoculations with four lineage 1 WNV strains, three from southern Europe (Italy/2008, Italy/2009 and Spain/2007) and one from North America (NY99) were performed on house sparrows (Passer domesticus), a wild passerine common in both continents. Non-significant differences which ranged from 0% to 25% were observed in mortality for the different WNV strains.

... Consequently, albeit being pathogenic for house sparrows, some Euro-Mediterranean strains had reduced capacity for replication in -and transmission from- this host, as compared to the NY99 strain. If applicable also to other wild bird host species, this relatively reduced transmission capacity of the Euro-Mediterranean strains could explain the lower incidence of this disease in wild birds in the Euro-Mediterranean area.

Crisis biology: Can bacteria save bats and frogs from deadly diseases?

As populations plummet, biologists race for a solution.

In 2007, Valerie McKenzie volunteered for a large study of human body bacteria. It was the dawn of the golden age of the microbe. Researchers were just beginning to understand how bacteria and other microbes in human intestines influence everything from obesity to allergies and infections. McKenzie, a University of Colorado-Boulder biologist, was mildly curious about her "microbiome." But she was more interested in the bacteria living on the skin of frogs and toads.

Amphibian populations worldwide are plummeting, and entire species are going extinct. The West's struggling species include boreal toads and mountain yellow-legged frogs. Invasive species and habitat degradation play a major role, but amphibians are dying even in places with good habitat. Batrachochytrium dendrobatidis, an aggressive fungus commonly known as chytrid, is often to blame.

McKenzie, who was studying the role of farmland conversion and suburbanization in the decline of leopard frogs in Colorado, suspected chytrid was also a factor. When she read a paper about a strain of bacteria found on red-backed salamanders that inhibited chytrid's growth, she began to wonder: What microbes lived on the skin of her frogs and toads? And could any of them fight chytrid?

Infected Tasmanian devils reveal how cancer cells evolve in response to humans

Tasmanian Devil Facial Tumor Disease (DFTD) has ravaged the world's largest carnivorous marsupial since it emerged in 1996, resulting in a population decline of over 90%. Conservation work to defeat the disease has including removing infected individuals from the population and new research explains how this gives us a unique opportunity to understand how human selection alters the evolution of cancerous cells.

DFTD is an asexually reproducing clonal cell line, which during the last 16 years has been exposed to negative effects as infected devils, approximately 33% of the population, have been removed from one site, the Forestier Peninsula, in Tasmania between 2006 and 2010.

Partnership fights for ban on hunting with lead ammo

California bill A.B. 711 requires the use of non-lead ammunition in all hunting of mammals, birds, and other wildlife. Audubon California, The Humane Society of the United Sates, and Defenders of Wildlife joined forces to get the bill passed.

“Our three organizations worked together on a 2008 bill that limited use of lead ammunition in about 20% of California,” says Jennifer Fearing, California senior state director of The Humane Society of the United States. “A.B. 711 would extend this requirement to the rest of the state.”

Garrison Frost, director of marketing and communications for Audubon California, says lead poisoning is a leading cause of death among wildlife that feeds on animals killed by lead ammunition. In addition, lead ammunition that seeps into the food chain, watershed, and overall environment poses a broader treat to human health.

RARE FERRETS NEED MORE LAND TO SURVIVE THE PLAGUE

The black-footed ferret is one of the most endangered mammals in North America, but new research suggests that these charismatic critters can persist if conservationists think big enough.

Decades of human persecution (e.g., poisoning) of the ferret’s favorite prey, prairie dogs, and severe outbreaks of plague and distemper led to its extinction in the wild in 1987.

Since then, thousands of captive-raised ferrets have been released across North America, and at least four wild populations have been successfully reestablished.

However, a new factor threatens to undermine these hard-fought conservation gains: the continued eastward spread of the exotic bacterial disease plague, which is a quick and efficient killer of prairie dogs, and is caused by the same microbe that is implicated in the Black Death pandemics of the Middle Ages.

Using a new multi-species computer modeling approach, researchers have linked models of plague, prairie dogs, and black-footed ferrets to explore the consequences of ecological interactions in ways not possible using standard methods.
The results of this study, published in Journal of Applied Ecology, suggest that the continued survival of black-footed ferret populations requires landscapes larger than conservationists previously thought, and intensive management actions to reduce plague transmission.

Honeybee trade is hotbed for carrying disease into wild and other wildlife health news stories

Study reveals new ways deadly squirrelpox is transmitted to red squirrels

Native red squirrels have declined throughout Britain and Ireland for the last century due to a combination of habitat loss and the introduction of the North American eastern grey squirrel. But more recently its few remaining populations have been devastated by an insidious pox virus passed to them by the alien invaders.

A study by the biodiversity and conservation research centre Quercus at Queen's University Belfast (QUB), and published in the journal PLOS ONE, found the situation may be worse than previously thought as the disease appears to have multiple modes of potential transmission. The project was part-funded by the Northern Ireland Environment Agency (NIEA) through the Natural Heritage Research Partnership (NHRP) with Quercus, Queen's University Belfast and part-funded by the People's Trust for Endangered Species (PTES).

Invading grey squirrels, which harbour the disease but typically do not suffer symptoms, may pass the virus in their urine. The research team conducted experiments to examine the survival of the virus outside the body in the wider environment, showing that it persists best in warm dry conditions. This raises the possibility that infected grey squirrels could pass on the disease by uninfected squirrels coming into contact with their dried urine during spring and summer.

The virus was also found in the parasites of pox positive squirrels including fleas, mites and ticks, which are capable of carrying the disease between individuals or between the species.

Honeybee trade is hotbed for carrying disease into wild

HONEYBEES have been busy – spreading diseases to insects that pollinate crops. It seems imported honeybees are an important reservoir for viruses that kill wild pollinators, which could lead to a meltdown in the planet's pollination services.

World trade in honeybee colonies contributes to honey production and also plays a vital role in agriculture – in some cases there would be no crop without the pollinators.

Honeybee colonies in Europe and North America have suffered recent mysterious declines. But now it seems the colonies could be just as much of a threat to wild pollinators such as bumblebees and the many species of "solitary" bees.

Matthias Fürst of Royal Holloway, University of London tracked the geographical prevalence in the UK of a non-native parasite called deformed wing virus (DWV) that is often found in both honeybees and bumblebees. The virus is spread by a mite and typically kills bees within 48 hours. The pattern of spread showed that imported honeybees are the major source of infection for the wild pollinators, and that emerging diseases spread by those colonies could be a major cause of mortality in the wild

Coral off WA suffers shocking damage from marine heatwaves, scientists say

Study reveals that remote reef with coral hundreds of years old has undergone severe bleaching and ‘decimation’

Marine heatwaves have wreaked “almost unprecedented” damage to ancient coral off Western Australia’s Pilbara coast, scientists say.

Preliminary results from a five-year year study of the coastline revealed that a remote section of reef south of Barrow Island has suffered severe “bleaching and decimation”, according to the CSIRO, which is running the study with the University of Western Australia.

An extreme “bleaching event” in 2011 was known to have caused significant damage to the reef. But the study found another marine heatwave, in the summer of 2012-13, also caused trauma to the reef, including to its massive, 400-year old porites corals.
