Destruction – See Animals Wild

Goulds mouse, thought extinct for 125 years, lives on

The mouse was considered to be stuck on the mainland, which means that if true it would have been lost for good.

Thankfully this was not the case.

This mouse was living under the identity of the Djoongari mouse, or the Shark bay mouse, on an island in shark bay.

Furthermore, by looking at the genetic diversity of these mice (from specimens taken at the time) was high, which makes it clear that right before extinction, there were large numbers of these animals. This means that their extinction was not a natural process as had been assumed, but is instead an issue with human arrival.

Instead, extinct is likely due to a mixture of

Introduction of predators in the form of domestic cats and foxes
changes to fire management (carried out effectively before European arrival)
Introduction of new diseases
Habitat destruction due to industrialisation and land clearing for agriculture.

While these mice are unlikely to be possible to return to the mainland for some time (until feral cats and other species are eliminated) they can perhaps be introduced to other small islands to guarantee their survival.

Ocelot

Ocelots, servals are about the size of domestic cats, which mean that without being careful it is easy to overlook them. Found throughout the south west of the USA, Mexico, and on through central and South America, as well as the Caribbean island of Margarita and Trinidad. At this time, two subspecies of Ocelot are recognized (in the past as much as 9 subspecies were proposed) and these are essentially split by continent (a north America Ocelot and a Southern America Ocelot).

Researchers agree that there are around 120 wild Ocelots in Texas but elsewhere it is less clear. Indeed, the Ocelot is generally listed as least concern, though in various parts of its range it is threatened by habitat destruction, hunting or traffic accidents. As such while its range is very large there are areas where it is decreasing in an area of its range. The ocelot has had occasional association with humans dating back as far as the Incas and the Aztecs – and has occasionally been kept as a pet.

Guina (also called the Kodkod)

Guina or Kodkod

The Guina is found primarily in central and Southern Chile, as well as in parts of Argentina at the same latitudes.

Melanistic (black versions) do occur in places. It is usually found in mixed temperate rainforests of the Southern Andean chain and coastal areas such as the Valdivian and Araucaria Forests of Chile, which has bamboo in its lower levels. It prefers evergreen temperate rainforests to deciduous temerate moist forests (or scierophyllous scrub or coniferous forests). It can be found in altered forest, so does alright in areas where humans have disturbed the forest, or in the edges of settled and cultivated areas. It is found as high as 1900m (which is at the treeline) In Argentina it has been recorded in moist Montane forest, which has Valdivian temperate rainforest characteristics, including those with many layered structure with bamboo or numerous lianas and epiphytes.

They are equally happy to be active in the day or the night, though rarely venture into open spaces during the day.

The main threat to their survival is the destruction of the rainforest. Those living near human habitation have also been killed after taking chickens. They are classed as vulnerable.
