Distribution, diversity, and latitude in African primates
Article Abstract:
The latitudinal distribution of African primates was analyzed to prove whether or not the latitudinal ranges of species become progressively smaller toward the equator. Results suggest that the geographical range of species is dependent on the adaptation to climatic variability. However, results also reveal that the relationship between geographical range and adaptation will not necessarily lead to the covariation between geographical range and latitude. Furthermore, the latitudinal gradients between primate species richness and geographical range can exist independently.

Persistence and area effects in a stochastic tritophic model
Article Abstract:
A study was conducted on the effects of metapopulation size on multispecies community persistence, with particular emphasis on food chains, using a reformulated deterministic host-parasitoid model. Results show that the minimum lattice size required for persistence is increased by demographic stochasticity-induced extinctions. Results also reveal that demographic, stochastic effects disproportionately influence host and parasitoid communities with significantly asymmetric dispersal rates.
