Tiny victims of roadside litterbugs: Three million mice and voles die trapped in bottles and cans thrown from cars



Volunteers checking empty bottles and cans found the remains of tiny animals 
Some 3.2million voles, shrews and mice die as they crawl in and cannot escape

Millions of Britain’s smallest mammals are killed each year because of litter dumped on the roadside, a disturbing study has found.

As many as 3.2million voles, shrews and mice die when they crawl into discarded bottles and cans and are unable to get out.

Volunteers who checked hundreds of bottles and cans for the study found the remains of dozens of tiny animals. Desperate for shelter, they had ended up trapped and had starved to death.

Plastic bottles were the worst offenders, with one in eight containing a tiny dead animal and some packed with as many as seven.

Small mammals are integral to the food chain – eating insects and plants and providing food for larger animals and rare birds such as owls and kestrels.

The 18-month study was led by RSPB volunteer Graham Moates, who had help from charity Keep Britain Tidy.

Mr Moates was appalled at what he found in the rubbish littering the roads, mainly around south Norfolk. Of the 2,174 bottles and cans collected, there were 230 dead animals inside – one for every ten discarded containers. Of these, 118 were common shrews and 59 were bank voles. Based on what he found, Mr Moates calculates that across the country, up to 3.2million animals end up dying this way every year.

‘I never thought it could be this many before I began the research,’ he said.

‘I was expecting an occupancy rate of about one per cent, but it was more than five times that. It is very upsetting to think of how many small creatures die in this way because of human carelessness.’ New regulations making it easier for councils to clamp down on littering motorists come into force next month.

Fines can now be issued to the registered keeper of the vehicle, regardless of who threw the litter. And Keep Britain Tidy has unveiled a campaign aimed at motorists, urging them to think before they throw rubbish from their cars.

TV presenter and Keep Britain Tidy ambassador Chris Packham said those who care about the country’s wildlife must act now, adding: ‘We have all seen the impact of plastic bottles on our marine environment in recent months. Now, thanks to this research, we know it is killing millions of the small mammals that are a vital source of food for our native birds of prey.’ Keep Britain Tidy chief executive Allison Ogden- Newton urged councils to use CCTV footage and their new powers to fine offenders.

‘We are spending millions every year cleaning up after selfish drivers who seem to think it is acceptable to throw their rubbish out of their cars, turning our roadsides into a giant heartless wasteland,’ she said.

Vole Population Booms on the Decline in Europe


Tanya Lewis, LiveScience Staff Writer
Date: 04 April 2013 Time: 02:53 PM ET

Herbivorous voles play a critical role in the food chain. They are prey for many predators and important consumers of vegetation. Historically, voles have had three- to five-year boom-and-bust population cycles. However, over the past half-century, these cycles have been much less pronounced, a new study finds. The widespread flattening of vole populations may be due to climate change, and it could have detrimental effects on species that rely on these little creatures.

Voles are close to the bottom of the food chain, and the fate of these animals tends to have a ripple effect on the rest of the ecosystem, said ecologist Xavier Lambin of the University of Aberdeen in the U.K., and senior author of the study published today (April 4) in the journal Science.

Rodents make vole hills out of Swiss mountains


An extraordinary invasion of voles has caused extensive damage to farmlands in the Jura, damaging crops and testing the patience of local farmers.

For the past two years, farmers have complained of the extraordinary invasion of voles in the Jura mountains. At the height of spring, their numbers were estimated at 1,000 animals per hectare, newspaper Tribune de Genève reported.

The rodents’ arrival, labeled a “swarm” by Vincent Wermeille, a farmer and member of the Grand Council of the Jura, has destroyed crops and caused millions of francs worth of damage.

The invasion has affected all peaks in the canton, Jean-Paul Lachat, head of the Centre of Rural Economy of the Jura, told the newspaper. With the crisis at its height, not even the extensive laying of traps helps to keep numbers down, he added.

Even the football pitch at Saignelégier has become unplayable after the animals wrecked the ground, leaving mounds all over and the surface unstable.

Last year, the voles ate every single blade of grass from certain fields.

“The fields were brown, it was like a desert,” farmer Rudolph Ackermann told the newspaper.

Some had got so fat, they no longer took their own tunnels, instead preferring to wander along the roads.

Even though the farmers have planted seedlings to replace some of the grasses eaten by the voles, certain fields are only expected to give some 50 percent of their yields.

"Some farmers are already at the wire," Wermeille told the newspaper. “The problems will come in November or December when there won’t be any grass left."

The farmers fear the worst once more, and worry about the cost of buying cattle feed from neighbouring France, as they were forced to do last year. The breadth of the problem also raises concerns that the price for alfalfa, bought as a replacement for the missing haystacks, will rise if everyone buys at the same time.

Farmers are now seeking help from Bern, wanting indemnification for the damage caused. But Denis Morand from the Federal Office for Agriculture advised that the extent of support demanded by the farmers could not be given.

Sexually rampant voles ruin Yorkshire village's tourist trade

METRO REPORTER - 16th June, 2010

Visitors to Flaxton in north Yorkshire are being forced to take a 10km (six-mile) diversion because of a colony of breeding water voles.

The village’s shops and pub are suffering a trading slump after bridge repairs had to be suspended until the autumn – when the voles have finished mating.

Landlady Lorraine Ritchie, of the Blacksmith’s Arms, said: ‘We’re losing £700 a week and this is the busiest time of the year. We’ve come through the recession and we can’t get on.’

Watch out Mr Toad, Ratty's eating frogs

LONDON (Reuters) - British ecologists have discovered evidence that normally herbivorous water voles living alongside canals and rivers have been eating frogs' legs this Spring. The timid water vole, immortalised as "Ratty" in the "Wind in the Willows" children's novel and films, is Britain's fastest declining mammal and is known to have a largely vegetarian diet consisting of grass and plants.

LONDON (Reuters) - British ecologists have discovered evidence that normally herbivorous water voles living alongside canals and rivers have been eating frogs' legs this Spring.

The timid water vole, immortalised as "Ratty" in the "Wind in the Willows" children's novel and films, is Britain's fastest declining mammal and is known to have a largely vegetarian diet consisting of grass and plants.

However, a survey along the Kennet & Avon Canal in the southern English county of Berkshire has revealed that these shy, furry animals have developed a taste for continental cuisine and have been snacking on frogs' legs, as well as the odd snail, British Waterways said in a statement on its website.

British Waterways ecologist Robert Randall said his team found a number of typical water vole feeding areas that were littered with dead frogs, minus their legs.

"We're not really sure why it's happening, but as the evidence coincides with the water voles' breeding season, we think it may be that pregnant mothers are snacking on frogs' legs as they lack protein in their diet," he added.

"This is incredibly unusual behaviour and as far as we know this is the first recorded evidence we have of them eating frogs' legs, so it's a really exciting discovery."

British Waterways asked people to report any water voles they see or any other wildlife activity in the country's canals and rivers on its website at www.waterscape.com/wildlifesurvey.

Voles' frog food

05 May 2010 16:30 GMT

British water voles have been eating frog's legs.

Researchers in Berkshire, England, were stunned to discover a group of the rodents have been dining on the tasty treats - typically served as a delicacy in French restaurants - possibly as a way of getting protein into their usually vegetarian diet.

Ecologist Oda Dijksterhuis said: "We found a number of typical water vole feeding areas that were littered with dead frogs, minus their legs.

"As a water vole's diet is normally vegetarian, this rather gruesome scene isn't what we'd expect to find at all."

Numbers of water voles are decreasing in the UK, with as little as 220,000 thought to now live there - down from eight million in 1960.

Researchers create first transgenic prairie voles

December 1, 2009

Researchers at the Yerkes National Primate Research Center, Emory University, have successfully generated the first transgenic prairie voles, an important step toward unlocking the genetic secrets of pair bonding. The future application of this technology will enable scientists to perform a host of genetic manipulations that will help identify the brain mechanisms of social bonding and other complex social behaviors. This advancement may also have important implications for understanding and treating psychiatric disorders associated with impairments in social behavior. The study is available in the December issue of Biology of Reproduction.

Lead researcher Zoe Donaldson, PhD, and her colleagues adapted transgenic technology to the prairie vole, a naturally occurring monogamous rodent that is being used to discover the brain mechanisms underlying monogamous pair bonds.

"Domesticated lab rats and mice dominate biomedical research, but wild rodent species with more complex social behaviors are better suited for investigating the biology of the social brain. Until now, genetic engineering among rodents has been limited to and rats," says Donaldson.

Single-cell prairie vole embryos were injected with a lentivirus containing a gene found in glowing jellyfish. The gene encodes a green fluorescent protein, which glows under the appropriate conditions. The prairie vole that developed from this embryo expressed the green fluorescent protein throughout its body, and the foreign gene was passed on to the offspring for multiple generations.

Larry Young, PhD, a Yerkes-based senior investigator on the study and an expert in , will next use this technology to determine whether monogamy and its associated social behaviors can be affected by manipulating a single gene. Researchers are also investigating ways to refine this technology in order to alter gene expression in certain as well as at certain developmental milestones.
