Climate change also increases both the frequency and intensity of extreme weather events, [7] which can directly wipe out regional populations of species. [8] Those species occupying coastal and low-lying island habitats can also become extinct by sea level rise. This has already happened with Bramble Cay melomys in Australia. [9]
Human-caused climate change and the rise in invasive species are directly linked to changing of ecosystems. [6] [7] The destabilization of climate factors in these ecosystems can lead to the creation of a more hospitable habitat for invasive species, thus allowing them to spread beyond their original geographic boundaries.

Hunting of tigers for illegal trade of body parts and opportunistic hunting of tiger prey species were considered the main threats to the country's tiger population. [41] Five tigers were recorded in Nam Et-Phou Louey National Protected Area between April 2003 and June 2004. Large wild prey species occurred at low densities so that tigers ...
Descriptions of the thylacine come from preserved specimens, fossil records, skins and skeletal remains, and black and white photographs and film of the animal both in captivity and from the field. The thylacine resembled a large, short-haired dog with a stiff tail which smoothly extended from the body in a way similar to that of a kangaroo. [31]
[2] [3] Climate change represents long-term changes in temperature and average weather patterns. [4] [5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6] As a region's climate changes, a change in its flora and fauna follows. [7]
Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems). [23]
Climate-based movement of tigers northwards may lead to increased conflict with people. From 1987 to 1997, Sumatran tigers reportedly killed 146 people and at least 870 livestock. In West Sumatra, Riau, and Aceh, a total of 128 incidents were reported; 265 tigers were killed and 97 captured in response, and 35 more tigers were killed from 1998 ...
The identification of a factor as limiting is possible only in distinction to one or more other factors that are non-limiting. Disciplines differ in their use of the term as to whether they allow the simultaneous existence of more than one limiting factor (which may then be called "co-limiting"), but they all require the existence of at least one non-limiting factor when the terms are used.
