- Diversification of species can be driven by factors such as physiological or morphological features of the species. These types of factors are called 1)heterogenous 2) extrinsic 3) endogenousarrow_forward1) A mathematical (differential equation) representation for a metapopulation can be written as dp/dt = cp(1- p) - ep where p is the proportion of patches occupied at time t, c is the rate of patch colonization, and e is the rate of patch extinction. The term on the left hand side is the ‘rate of change in the proportion of patches occupied.’ The first term on the right hand side of the equation provides the effective gain in patch occupancy as a function of p due to the colonization process, and the term in parentheses represents the fraction of patches not currently occupied. The second right hand side term provides the effective loss of patch occupancy due to the (local) extinction process. a) Look at the term for the colonization process. How would you modify this term if you wanted to capture the idea that habitat loss destroyed (i.e., made uninhabitable) a proportion D from the patches that are available for colonization ? b) What value of D guarantees complete extinction of…arrow_forwardFor the metapopulation of Daphnia in Scandinavian freshwater pools, which situation would be most likely to result in maintenance of the metapopulation, rather than its extinction?
