You are comparing two wetlands, one with high biodiversity and one with lower biodiversity.  Based on general patterns we have discussed in class and in weekly projects, you might predict the higher biodiversity wetland would have: susceptibility to invasive species compared to the lower biodiversity wetland productivity compared to the lower biodiversity wetland rank-abundance curve compared to the lower biodiversity wetland similarity between individual sampling quadrats compared to the lower biodiversity wetland.  

Based on the current trends shown in the population pyramids, which region is more likely to experience population stabilization or decline in the future, and why?

To support species native to Australia, Arid Recovery has created a relatively cat-free preserve by fencing and eliminating cats from a sanctuary.  Here is a photo of the set up and an adorable native Australian stick-nest rat from Arid Recovery’s website. Based on the success of the project, they plan to expand their program to protect more land from cats.  Imagine you are an ecologist consulting with them on this expansion.  List 3 suggestions you would make to the team as they consider the size, shape and/or location of additional protected land.  Back up each suggestion by briefly explaining the ecological principle it is based on.   1.  Suggestion 1 with supporting ecology principle. 2.  Suggestion 2 with supporting ecology principle. 3.  Suggestion 3 with supporting ecology principle.

According to the redundancy hypothesis, species are redundant if
