One possible hypothesis for the reduction over time of certain animal populations and not others could be that the increasing human population in the region has led to increased hunting and habitat destruction, resulting in the decline of larger animal populations. Factors that may explain the presence of the animal populations that are present in the community could include their ability to adapt to changing environments, access to sufficient food sources, and reproductive success rates.
