ENVIRONMENTAL SYSTEMS AND CLIMATE CHANGE
The spatio – temporary dispersal of environmental variables determines the species geographical range, this helps in describing the occupied fundamental niche, which is the habitant of the species (Hutchison 1957, Kearney 2006). An increase in evidence shows that the wide varieties of taxa geographical ranges are greatly shifting in response to climatic change.
The mammalians species thermal niche is determined by the changing spatio – temporal dispersal of temperature (Wealther et al. 2002, Parmesan & Yohe 2003, Thomas 2010), the ecological niche models demonstrates that for such a shift there are highly like hoods to continue with advance changes in climate (Learmonth et al. 2006).
In the context of this rationale, the ranges of mammals’ species are anticipated to shift in response to advance climate effects if probably the qualitative framework for considering the expected direction of mammals range changes, this suggest that almost all the mammals species ranges will be affected with the temperature, and may results to negative conservation consequences for all the species.
In addition, strategies of conservation and management will require rational understanding of how mammals’ species disperse for their effective implementation.
Effects of climatic change on mammals
The advance climatic change on the mammals’ species niche will directly affect the availability of vegetation through formation of drought, this will highly affect directly the feeding of the mammals species that depend on vegetation as food, there will be more scramble and fighting for limited vegetation that will still be there to support their existence, similarly the effect will be felt on the availability of rivers which will start drying on this particular forest habitant, it will either push out the their presences in this niche as they will be searching for water too for their existence, finally if the food and water will end up being exhausted at a great advanced climatic change, then the mammals will end up feeding on themselves or all will die.
Because of high increase evidence on the significant impact on global climate the mammals will adapt effectively for their existence in the following ways; first the mammals’ species will change their phenotype, which means changing the physical features in order to cope up with new environmental changes, secondly animals will start migrating and moving to an environment that is better suitable in an effort to handle the climate change, thirdly, the animals will adopt ability to withstand a large range of condition, for example Kangaroo has a very broad climatic tolerance, fourthly, other mammals will be opportunistic species in that they will feed and adapt to many changes in either feeding amongst themselves or feeding on particular animals.
Factors that will influence the response
Effect of altitude
At higher altitude the climate becomes colder hence no vegetation can be able to grow on such area similar too animals will have difficulty of their existence in such niche environment
