India Plans To Put Monkeys On Birth Control (VIDEO)

A rising population of menacing monkeys has become quite the problem for civilians in major cities throughout India, and the conflict has gotten so out of hand that government wildlife officials are looking into putting the primates on the pill, the Telegraph reports.

As the forested areas of the country rapidly disappear due to urbanization, the red-bottomed rhesus macaques (or Bhandar monkey) is forced to rampage cities in search of food, the report notes.

Will elephant contraception work in South Africa?


Birth control for elephants in South Africa is being hailed as a success, after the introduction of a contraception vaccine being trialled by researchers.
Wildlife conservationists believe it is likely to become the way to control South Africa's ever-expanding elephant population.
But the plans have provoked considerable controversy.
Some of the country's most eminent elephant experts are completely opposed to the contraception programme.
Elephants eat an estimated 270kg (600lbs) of food a day and can be extremely destructive while feeding, pushing over trees or breaking off branches.
Unlike in many African countries, where poaching has recently been having a devastating effect on elephant numbers, in South Africa the population is estimated at about 20,000.
For the last five years, wildlife experts in the Tembe Elephant Park, which borders Mozambique, have been firing the contraceptives into the female elephants from the air.
The 300 sq km (115 sq mile) park in KwaZulu Natal province has 200 elephants in its herd - some of southern Africa's largest giant animals with magnificent tusks.

Dartmoor ponies to go on the pill

World Horse Welfare vets given go-ahead to use contraceptive injection on mares after Devon population explosion

A pioneering project to put Dartmoor's wild ponies on the pill is to begin in Devon later this year.
Concerns has been growing for several years about overbreeding among the semi-feral animals, high numbers of which have ended up in horse sanctuaries or slaughtered and the meat sold overseas as their market value has plummeted.
The recession has further affected sales of the ponies, with less people prepared to take on and train up a half-wild animal, despite their temperaments and intelligence making them ideal as children's riding ponies.
Now vets working for World Horse Welfare have been given the go-ahead to bring in injection from Australia to control the numbers of foals being born on the moor.
WHW veterinary consultant Keith Meldrum has been working closely with the Dartmoor Hill Pony Association (DHPA) and the pharmaceutical company Pfizer on proposed plans to provide a group of 20 mares with a contraceptive injection.
"A project of this kind has never been carried out before in the UK and I am delighted to be a part of it," he said. "We are hoping that, if successful, this could become a long-term solution to the issue of overbreeding within Britain's semi-feral horse and pony populations."
Meldrum said the treatment was not as invasive as sterilising the mares.
"We feel that this method of control is advantageous as the mares can come back into foal after the treatment; its simply means there is simply a reduction in foal production for the duration of the project. We are close to starting the initial injections now that we have the [drug] in our possession and after the Veterinary Medicines Directorate gave us the go ahead for batches to be imported from Australia into the UK."
There are thought to be less than 1,000 of the ponies left on the moor, down from an estimated 25,000 in the 1930s. In late spring a team led by Meldrum plan to round up ponies into a holding area where they will be micro-chipped and marked in a way in which they are identifiable at a distance. They will then be given an injection, and four weeks later given a second dose.
After a six-month period the mares will be blood-tested to see if their oestrus levels have been suppressed owing to the injection. If the mares respond positively after the initial six months, then they will receive a further does which will last until spring 2013.
The secretary of the DHPA, Charlotte Faulkner said: 'The adult pony numbers on the moor need to be maintained at its present number for the benefit of Dartmoor, but the number of foals need to be reduced as there is no market for them at the moment.
"Controlling the production of unwanted foals will ensure the ponies' welfare. We are optimistic that this project will help us to ensure the future of ponies on Dartmoor, grazing to keep it as we know and love it for generations to come, creating the habitat for its wonderful birds, plants and animals to be conserved."
The project is being sponsored by Friends of the Dartmoor Hill Pony.

Elephant contraception possible to save from culling

Contraception May Save Future Elephants from Culling

In South Africa they have a problem, a big one: too many elephants.
For most of the 1900s extensive poaching threatened to wipe out the country’s elephants. In response, conservationists established reserves throughout the region and relocated as many herds as they could. Now those herds are doing quite well. So well, in fact, that they’re causing problems. Wildlife managers are currently facing a dilemma: how to deal with too many elephants. While some advocate for culling the giants, a group of scientists has outlined a different plan to control their populations: contraception.

Rather than simply setting a quota and culling the extras, immunocontraception could be a tool to allow land managers to control elephant populations in response to conditions on the ground such as food availability. "The approach now has to be much more dynamic and look at the influence the animals are having on the land," says Robert Slotow, a biologist at the Amarula Elephant Research Program in Durban, South Africa. His team recently published a paper in PLoS ONE describing how scientists might be able to use immunocontraception—a vaccine that gets the body to make antibodies that target sperm receptors on the surface of the egg cell. Slotow and his team outlined an immunocontraception schedule that would halt the growth of herds in a South African park and even out their population structure.

The problem
In the wild, two things control elephant populations: natural mortality and environmental conditions. Calves and full-grown animals get sick and die from all kinds of things, from predation to viruses. And when the environment is unfavorable–during years of drought or food shortages, for instance–females will put off having babies. In closed systems like conservation parks, however, neither of those controls is in place. The fences around the park keep out new animals and pathogens, and controlled park conditions make sure that there is ample food. Mothers keep having babies, and the death rate seems to slow to a crawl
