PhD project title: The impact of wildlife tourism on elephants, Loxodonta africana, in South Africa.

I am studying the behaviour of wild African elephants, Loxodonta africana, in a South African National Park. Madikwe Game Reserve holds over 1200 elephants, currently presenting the highest density of elephants in South Africa. The original breeding population was translocated there from traumatic backgrounds such as culling and heavy poaching.
As part of my research I study the effect of non-consumptive wildlife tourism on free-ranging elephants.
I collected five minute focal animal observations as well as herd scan samples on known and random individuals. Additionally, I collected faecal samples for stress hormone and thyroid hormone analysis and recorded vocalisations at the herd level for analysis of variations in fundamental frequency. Satellite collared females provided spatial data for home range and spatial analysis.
Analyses showed that elephants became increasingly likely to perform aggressive behaviours towards their conspecifics, when tourist pressure (total number of tourist in the reserve) increased. Elephant herds became increasingly likely to move away when increasing numbers of tourist vehicles were present. Physiological stress hormone concentrations also increased with increasing tourist pressure.
This reserach will increase our understanding of this population and inform local management in terms of potential stressors to the elephants. It is also the first to investigate how wildlife tourism affects elephants. Additionally, hormone analysis will further our knowledge about stress hormone levels and be the first of its kind to analyse thyroid hormones in wild elephants.
