Elephant anatomy is very much comparable to the horse and rabbit. Microbes are present in the hindgut that produce Volatile Fatty Acids (VFAs). VFAs make a substantial contribution to the elephant's total energy requirements. Food has a relatively fast transit time and as a result, elephants have a low digestive efficiency (44% as opposed to 60% in horses). A fast transit time is achieved by a short GIT, reduced caecum and increased GIT diameter. Their digestive strategy is to pass as large a quantity of low quality food through their digestive tract within a short period of time.

The exploitation of African elephants in the form of ivory poaching is exacerbated by warfare. The affects of this anthropogenic evolutionary force on the African savanna elephant (Loxodonta africana) in the Gorongoas National Park in Mozambique was investigated (Campbell-Staton, et. al. 2021) after the Mozambican civil war (1997-1992). This multipart lesson is based on this research. Here, we explore allele frequencies, phenotypic data, and the use of a chi-squared test to determine if the population is in Hardy-Weinberg Equilibrium. Because one gene influencing tusklessness is X-linked, we also explore inheritance of the trait, using hemophilia as an example. The data used in this part of the lesson are simulated data based on reports from Zambia.

This online textbook chapter will provide students with an understanding of the mourning behaviors in animals. It explores the different definitions used to compile the data today and provides examples across a variety of species including non-human primates, crows, elephants, dolphins, and whales. Multiple studies are cited which aim to collect first hand observational data as well as data analyzation from a variety of perspectives around the globe.
