ProposalDescription: 

This research proposes to investigate the histology of the teeths of the giraffids, Sivatherium hendeyi and Giraffa Jumae from the Pliocnene locality, Langebaan, to deduce information about various aspects of their life-history, such as age at maturity, growth rate, age at death and/or age at weaning. I have attached a more detailed research proposal. Cape Town, Western Cape.

Expanded_Motivation: 

Our aim is to deduce the life history traits of two extinct girrafids from Langebaanweg: Sivatherium hendeyi and Giraffa jumae through an analysis of the histology of their bones and teeth. The life history traits of an animal underlies its survival and reproduction. For example, age at first reproduction and age at death along with other biological characteristics that co-vary with them (e.g. growth rate, adult body size, size at birth), are considered life history traits. It is well recognised that life history traits are modulated by environmental conditions to maximize the reproductive success of the individual. More specifically, predation and resource availability are the main selection pressures that shape an individuals’ life history. Thus, the study of life histories, of extinct and extant animals provide valuable insights into many aspects of a species’ biology and ecology, including the ecological conditions of its ecosystem.
