in dangered species ?

sam111 · Feb 9, 2012

I am wondering if their is a site or database that allows you to look up the endangered species/ or animals/species population data.

I am wondering how the national parks ... like yellow stone ,...etc know when a certain animal is endangered or how they collect/ know for sure they are accurate.

For example Panda Bears are one animal that is on the endangered species list.
I am curious how they know this for sure and if their is a way to measure/get the population data of certain animals in certain regions.

Any environmentalist out their that can shed some light on this.
I am very interested in how one can gather data accurately on animals?
For people we can easily use surveys and tax forms to get a rough estimate on human population. (at least humans are a little easier to keep track of normally)
But when it comes to animals seems to me it would be nearly impossible.... and nearly impossible to know if an animal is on the in dangered species list or not.... or weather it is going to be.

Thanks your link explains most of what I wanted to know
Your link

But going by sampling in a small region the amount of particular animals doesn't always mean you are going to get a good approx. in the large always.

For example if you counted how many ants in a 10ft by 10ft area approx. You cann't just say an accurate number of ants for all of a particular town or state would be just multiplying
a 10ftx10ft area by a larger factor ...etc

To put it interms of human population if we counted all the people in a Wyoming based town/state got an average we could not use that number and multiply it to get an accurate
approx of the whole population of people in the US or in the world....etc

The point is human population is more dense in certain areas and I would assume animal population in alot of cases would be no different.

So with out a group of people assigned to count a specific region latitude/longitudes their would be no way to get a good density count. ANd with out a density count you would only have a very simple population measure that is not very accurate in most cases and wouldn't apply in most cases.

Think about if I wanted to see how many ants lived in Antarctic (their is probably none) but the approx. method would say multiply number of ants in 10ftx10ft by a factor of how big the region is. (this is a stupid example that could easily be cleared up by experimenting on one ant to see what climate it could live in and factor that in.... but the point is still their)

The whole point of environmental studies is that differant species have niches that require differant kinds of environments. So your 10' X 10' plot is good only if the two areas are the same in almost all respects. That is why real environmental studies require much time and effort.

Manaus is one of the host cities for the 2014 Fifa World Cup in Brazil...

Brazil's Amazon boom pits economic growth versus forest
7 April 2012 - Manaus districts are spreading further into the surrounding rainforest

Marcelo Gordo is standing in the back garden of a small house in a suburb of Manaus, the capital of Brazil's Amazonas state, hoping to catch sight of a pied tamarin. These small primates, with white upper bodies and brown bottoms, live only in rainforest surrounding the city and as Manaus grows and expands, they are becoming trapped in isolated patches of forest. Mr Gordo, a researcher from the Federal University of Amazonas, has been studying these creatures for some 14 years. He has pinpointed a group of about eight which live in a jungle-covered gully behind this row of houses. "They have a very strict geographical distribution and in the last few years they've been losing this space," he says. "If these animals had a very small geographic distribution in a different place, where they weren't competing with humans, there wouldn't be a problem, but they live right where Manaus is."

Located deep in the Amazon rainforest, Manaus would seem an unlikely place for a city. It flourished originally as the centre of the rubber boom in the late 1870s. Once rubber plantations were developed elsewhere, it lapsed into semi-obscurity once again. But in the 1960s the military government, installed by a coup, was looking to consolidate its control over the country with economic development and galvanise its control over the Amazon region. It encouraged businesses to expand into the area by offering generous tax breaks.

Tech companies

Manaus has grown in the ensuing decades. The population is now about 1.8 million, almost doubling in size since 1990. With Brazil's healthy economy, the city is booming once again. Many major multi-national technology manufacturers, like LG, Samsung and Philips, have a presence here and their business is swelling the population further. "It's not easy to find employees with the background that we, the companies, are looking for," says Wilson Perico, director of the Technicolor factory which makes modems and satellite decoders. "It's why some companies bring experts from other states or countries to help the new guys to develop their activity here."

The increase in workers in the city led to the decision to build a bridge over the Amazon to open up the south bank of the river to development. Inaugurated in late 2011, the Rio Negro bridge will give more commuters access to dormitory towns where developers are already building more housing. Other changes are on the way. Manaus will be one of the host cities when the Fifa World Cup takes place in Brazil in 2014. Construction is already under way on a 40,000-seater stadium and several new hotels are planned for the thousands of visitors who are expected to descend on the city. The tournament organisers have vowed the stadium will be environmentally friendly, using energy efficient lighting and harvesting rainwater.

Hmmm, same thing happened to a couple of my dad's ol' drinkin' buddies...

Liver disease causing wombats to go bald and die
Wed, May 16, 2012 - A mystery liver disease thought to be caused by introduced weeds is causing hairy-nosed wombats in southern Australia to go bald and die, researchers said yesterday.

The illness, which causes the wombat to lose some or all of its fur and then starve to death, is tearing through South Australias native southern hairy-nosed wombats, threatening entire populations. Peter Clements from the states Natural History Society said wildlife rescue workers had discovered several hundred sickened animals in the Murraylands region near Adelaide, where up to 85 percent of the population was unwell. They tend to lose their fur in patches and sometimes in whole, Clements said. You can see the bones showing through and theyre generally immobile, they just sit there in the sun all day and try to keep warm, he said.

Clements said it was unusual to see the wombat, a nocturnal creature, out during the day and when they were in daylight, we know that theyre in trouble. Initially the wombats were thought to have mange, but it became so widespread and severe that autopsies were carried out to determine the cause of the illness. University of Adelaide researcher Wayne Boardman said the non-native toxic potato weed appeared to be affecting the wombats livers, triggering a reaction with ultraviolet light that caused them to lose their fur.

Boardman said it was unclear why the herbivorous wombat had suddenly taken to eating the noxious weed, but a shortage of their usual grasses and alternative foods due to prolonged local drought could be to blame. We have a feeling it might well be a struggle to find enough vegetation, leading them to eat other plants like weeds, and particularly potato weed, which is then having a deleterious effect on the liver, Boardman told ABC Radio.

The creatures were also roaming in areas where they were not usually seen, supporting the theory that there were food shortages and they have to move out to find vegetation, he added. Squat and thickly furred, wombats are small burrow-dwelling marsupials that walk on all fours and are bear-like in appearance with a wide muzzle and a flattened head.

Brazil not doin' much of a job of protectin' rainforest...

Brazils Coastal Rainforest Suffers Widespread Species Extinction
August 14, 2012 - The Atlantic forest in Brazil, once a part of the great Amazon basin on the South American continent, is suffering from widespread species loss according to a new study.

Ecologist Carlos Peres with Englands University of East Anglia and then University of Cambridge graduate student Gustavo Canale traveled through the region between 2003 and 2005. They documented 200 of the largest and least disturbed old-growth forest fragments in the vast region of the Atlantic forest. On average, they found only four of the 18 mammal species they were looking for. Canale, now working in Brazil at the State University of Mato Grosso, says he and Peres drew largely on information from wildlife surveys, camera traps, and interviews with local people.

The scientists were surprised that even in what looked like healthy forest cover, the larger mammals were absent. The situation was worse than we thought, Canale said. All the charismatic species, said Peres, the large primates, the large ungulates, brocket deer, tapirs, giant anteaters, jaguars, the large cats, all of those things are pretty much gone from even fragments that look on the surface of it, okay, in terms of forest cover.

Hunting is the main driver of species loss on lands fragmented by deforestation. Peres says Brazilian law protects forest cover, but not wildlife in the remnant forest patches. Unless that law is changed, he says, the losses will continue. Essentially what we are calling for is a wholesale revision of the Brazilian legislative code that protects wildlife within these remnant forest patches," he said. "Because these remnant forest patches are essentially going out of business, if you like, in terms of the wildlife. In contrast, Peres says, in the five areas that did have laws to protect wildlife and where the laws were strictly enforced, the mammals did much better. In those five sites we find the highest degree of retention of those wildlife communities," he said. "So the protected areas are actually working in this region, the problem is that there are very few of them.

The researchers want to see more such areas established, as well as the creation of wildlife corridors that would link isolated forest patches and keep animals away from hunters and other hazards. But Peres also offers a cautionary message. He says the fragmented tropical forest isnt just a problem in the Atlantic forest of eastern Brazil. But I would argue that this is also happening throughout most of the worlds heavily fragmented biodiversity forest hotspots, where overhunting is also widespread, he said. "Holding on to the last remaining large tracts of primary forests will be a crucial part of the conservation mission of this century," Peres said. His and Gustavo Canales study on Brazils Atlantic forest is published in this weeks edition of the journal PloS ONE.
