Carrying capacity is A) seldom exceeded in real populations. B) the maximum population size that a particular environment can support. C) fixed for most species over most of their range most of the time. D) determined by density and dispersion data. E) the term used to describe the stress a population undergoes due to limited resources. 17) The small intestine has a very large surface area that directly facilitates high rates of A) digestion. B) absorption. C) elimination. D) filtration.

Oaks in California are suffering from a phenomenon called sudden oak death (SOD).  This has the potential to convert oak-dominated communities to communities made up of mostly grasses and smaller plants.  How would this change the abundances of the tick species described in the article?  Make a prediction for each of the three most abundant species, and describe the specific results in this article that justify your prediction.   Article Reference: Abiotic and habitat drivers of tick vector abundance, diversity, phenology and human encounter risk in southern California By: Andrew J MacDonald
