Summary Introduction
To write:
A scenario where a small island may or may not have a huge number of species.
Introduction:
In
Edward O. Wilson and Robert MacArthur proposed ‘The Equilibrium Model of Island Biogeography’ in 1960. It is a comprehensive model that explains uneven distribution on the new island.
According to Edward O. Wilson and Robert MacArthur, the number of species present on an island reflects the balance between the rates of immigration and extinction. The model predicts that island size is directly proportional to the number of species. The number of species increases with an increase in island size. The number of species decreases with decrease in the distance from the source pool.

Question: Which of the following hypothetical islands would likely have the greatest species richness? Group of answer choices A) Not enough information given B) a large island far from the mainland C) a large island near to the mainlandarrow_forward
- How does protecting the biodiversity of an area increases the survival of a species’ population? Use the principles of threats to biodiversity (e.g. overexploitation, habitat loss, invasive species, etc.), species dominance or evenness, and genetics of the species (e.g. inbreeding, mutations, founder effect bottlenecks, etc.). Use a Philippine endemic species as an example in your answer.arrow_forwardIn your region, what species are threatened with extinction? Why are they vulnerable? Suggest steps that could be taken to increase their populations.arrow_forwardIn what ways do you think species matter and it is important to protect species from extinction, or keep them flourishing? Is there something about species or biodiversity that makes it inherently to-be-valued?arrow_forward
- Would you classify these species as weak, moderate, or strong competitors? Think about population density.arrow_forwardEcologists use a rank-abundance curve to display relative species abundance, which is a component of biodiversity. It can also be used to demonstrate species richness and evenness. Figure 1 shows the rank- abundance curve for caddisflies (Order Trichoptera) of two aquatic habitats in northern Portugal (data from L.S.W. Tera). Pollution of streams, on the other hand, reduces the diversity of Trichoptera and several other groups of stream insects, reducing both species richness and species diversity. Interpret why those happened. These rank-abundance curves show that the mountain stream caddisfly community has higher species richness and greater species evenness. 0.1 - Mountain stream 0.01 Greater richness and species evenness 0,001 Coastal ponds 0.0001 20 40 60 80 Abundance rank Figure 1: Rank-abundance curve for caddisflies (Order Trichoptera) of two aquatic habitats in northern Portugal (data from L.S.W.
