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]
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
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 ...
A captive white tiger at the Singapore Zoo. The white tiger (ashy tiger) is a leucistic morph of the tiger, typically the Bengal tiger. It is occasionally reported in the Indian wilderness. It has the typical black stripes of a tiger, but its coat is otherwise white or near-white, and it has blue eyes.
It is related to some of the aforementioned threats to wildlife like habitat destruction and pollution. Rising temperatures, melting ice sheets, changes in precipitation patterns, severe droughts, more frequent heat waves, storm intensification, ocean acidification, and rising sea levels are some of the effects of climate change. [26]
The hierarchical model takes into consideration the requirements, impacts or resources as well as local extinctions in disturbance factors. Models can integrate the dispersal/migration model, the disturbance model, and abundance model. Species distribution models (SDMs) can be used to assess climate change impacts and conservation management ...
The annual question reaches peak curiosity this week, but as the planet warms due to human-caused climate change, the probability of seeing snow at Christmas is becoming increasingly unlikely ...
Extinction: The Facts is a 2020 documentary film by the natural historian David Attenborough which aired on the BBC. It depicts the continuing sixth mass extinction, caused by humans, and the consequences of biodiversity loss and climate change. It also suggests positive action which can be taken to halt or reverse these effects.
