The tiger is one of the most endangered species around the world. Today, there are only an estimated 5.000- 7.000 tigers existing worldwide (D'Silva, Roy) . This number has decreased drastically over the last few years, even though the tiger has few natural enemies. Besides large buffaloes, bears and elephants, humans are its worst enemy. Tigers mainly live in Asia, India and Russia. Due to the wide spread, every tiger sub- spices have adapted to its ecosystem differently, some live in tropical rainforests, mangrove swamps, grasslands or savannas. They have developed in different in size, color and behavior throughout the evolution.
There are three main reasons why the tiger is endangered. These include poaching, loss of their natural habitat …show more content…
They can then identify how well these areas suit and fulfill their needs. Scientists use different ways to collect data abut the tiger, some of the most common ones include, attaching radio collars to the animals, and the pugmark census technique ("Tiger Conservation.”). Here scientists detecting tracks that the tigers leave behind like paw prints. Considering factors like the amount of space, the distance to the nearest village/town, if there is enough prey and how densely the vegetation is in this area, so that the tiger is able to hunt. After collecting this information, scientists from different organizations inform the government about the conditions. This is very important, as they have rare and specific data to confront them with. In some cases, when it occurs that this area is very suitable for the tiger and many tigers live there, the government agrees to put a wildlife reserve around this …show more content…
Because populations of these species live together in one area, they will all interbreed. This will lower the gene flow (which is very important because it improves the animals ability to adapt to changes) over the years. However, scientists found an effective solution for this problem. It is important to maintain a good level of genetic diversity in the population, to produce healthy tigers ("Forest Corridors Help”). Genetic diversity is what makes individuals from the same species unlike the others. ("Biodiversity - Species Diversity.") It is important to have genetic diversity because it improves the ability to adapt to changes like a change in the climate ("Biodiversity - Species Diversity."). For this to happen, there has to be a relatively large population of tigers in the reserve, so that they can interbreed and exchange enough genes. In addition to that, the gene flow can be encouraged, by making forest corridors that connect different reserves or other protected areas to each other ("Forest Corridors Help”). Forest corridors are ways were animals can safely travel from protected areas to the next. This exchange of animal genes creates a kind of network. This can also be called ‘ecological network’ ("Sicirec -
