Question

Consider the effect of this development on the California Thrasher and the many species of plants and vertebrates found only in the intact chaparral of this region. For each biological process in part A through E, state whether each would increase, stay the same, or decrease as a result of fragmentation of chaparral habitat and briefly explain the rationale for your answer (no more than one sentence). A. Likelihood of local extinction of thrashers within any particular habitat fragment B. Likelihood of epidemic disease affecting all the thrashers in San Diego county C. Potential for genetic differentiation of thrasher populations among canyons D. The speed of recolonization of a particular canyon by thrashers after a fire causes extinction within that canyon. E. The ability of thrasher populations to migrate north in response to climate change Please clearly label your answer to each part A-E in the box below.

Answer 1

Habitat fragmentation refers to splitting the ecosystems further into smaller fragments based on the specific mechanisms that are often compensated for in the given sense by rising temperatures.

Explanation:

Thrasher's population is spread across San Diego county on patches.

A) The fragmentation of structures that enable can lead to the fauna and flora of the affected communities. As a result, this may impact the thrashers' survival pattern in the local habitats affected. This could, therefore, improve the probability of regionally endangered bruins in any specific area.

B) Local fragmentation will lead to further detachment of the district thrashers. Thrashers aren't active aerial genus and therefore mainly stay straight to the floor. Consequently, it is doubtful that any illness will spread through such coastal habitats whether there is much more blurring of not. Consequently, the probability of that continues the same.

C) Genetic differentiation refers to the utilization of diagnostic tools induced by certain forms of separation in three subgroups of communities. Habitat loss would increase alienation among the Community communities. Consequently, the probability of genetic variability will improve.

D) If a fire is extinguished in a specific gorge, the destruction of the ecosystems will reduce the ability of the bruins to resettle the ecosystems as the communities are already separated and, thus, their neighboring segregates will have less effect.

E) Climate change will also push the migration of thrashers to the north. This would be autonomous of the disintegration since instability doesn't help deter migration of populations. The likelihood of this thus continues to remain the same.
