Chemical Signaling In Asian Elephants (Elephas Maximus): Concentration Effects With Applications For Management And Conservation, Chase Andrew Ladue
Chemical Signaling In Asian Elephants (Elephas Maximus): Concentration Effects With Applications For Management And Conservation, Chase Andrew Ladue
Masters Theses & Specialist Projects
Asian elephants utilize two chemical signals that have been described to function in reproduction: (1) (Z)-7-dodecenyl acetate (Z7-12:Ac) is released by females near ovulation, and (2) frontalin is released by males around the time of musth. Signaling theory posits that the concentration at which either compound is emitted should have implications for the response of the receiver, varying with factors such as sex and reproductive experience. Here, the objectives were to: (1) investigate the effect of concentration on receiver chemosensory behavior in an effort to identify detection thresholds and concentrations of maximum response for reproductively experienced or inexperienced male and …
Wire Netting Reduces African Elephant (Loxodonta Africana) Impact To Selected Trees In South Africa, Kelly Derham, Michelle Henley, Bruce A. Schulte
Wire Netting Reduces African Elephant (Loxodonta Africana) Impact To Selected Trees In South Africa, Kelly Derham, Michelle Henley, Bruce A. Schulte
Biology Faculty Publications
African elephants (Loxodonta africana) are ecosystem engineers in that they substantially alter the environment through their unique foraging and feeding habits. At high densities, elephants potentially have negative impacts on the environment, specifically for large trees. Because of this, recent increases of elephants in the Associated Private Nature Reserves (APNR) on the western boundary of the Kruger National Park (KNP), South Africa, have caused concern regarding the survival of several tree species. Our objective was to assess the effectiveness of wrapping protective wire netting around the trunk of the tree for preventing and reducing bark stripping, branch breaking, …
Habituation To Auditory Stimuli By Captive African Elephants (Loxodonta Africana), Sarah Elizabeth Goodyear, Bruce A. Schulte
Habituation To Auditory Stimuli By Captive African Elephants (Loxodonta Africana), Sarah Elizabeth Goodyear, Bruce A. Schulte
Biology Faculty Publications
Habituation is a major concern for the development of effective, long-term human-wildlife conflict mitigation and zoo enrichment programs. Elephants are cognitive species that exhibit many types of learning, such as associative, social, and insight learning. However, no study has examined the habituation process in elephants. Elephants possess a well-developed sensory system and may habituate to stimuli that could be used for enrichment and/or management. The aim of this study was to examine their habituation process in response to repeated presentations of two auditory stimuli: buzzing by a disturbed beehive and the sound created by banging on pots and pans, and …
Assessing Perceived And Documented Crop Damage In A Tanzanian Village Impacted By Human-Elephant Conflict (Hec), Rebekah R. Hoffmeier-Karimi, Bruce A. Schulte
Assessing Perceived And Documented Crop Damage In A Tanzanian Village Impacted By Human-Elephant Conflict (Hec), Rebekah R. Hoffmeier-Karimi, Bruce A. Schulte
Biology Faculty Publications
In sub-Saharan Africa human-wildlife conflict (HWC) is a growing conservation issue and human-elephant conflict (HEC) is of special concern. Crop loss to wildlife comprises a main component of HWC. Deterrent methods for crop loss are numerous and such schemes could be more effective by an improved understanding of how farmers’ perceptions align with actual causes of crop loss. Our objective was to compare the perception by farmers of the causes and extent of crop damage to the measured crop damage in fields of maize (Zea mays) using different deterrent methods. We interviewed agriculturalists in the farming village of Miti Mirefu …
Impacts Of Environmental Pressures On The Reproductive Physiology Of Subpopulations Of Black Rhinoceros (Diceros Bicornis Bicornis) In Addo Elephant National Park, South Africa, Elizabeth Freeman, Jordana Meyer, Jed Bird, John Adendorff, Bruce A. Schulte, Rachel Santymire
Impacts Of Environmental Pressures On The Reproductive Physiology Of Subpopulations Of Black Rhinoceros (Diceros Bicornis Bicornis) In Addo Elephant National Park, South Africa, Elizabeth Freeman, Jordana Meyer, Jed Bird, John Adendorff, Bruce A. Schulte, Rachel Santymire
Biology Faculty Publications
Black rhinoceros are an icon for international conservation, yet little is known about their physiology due to their secretive nature. To overcome these challenges, non-invasive methods were used to monitor rhinoceros in two sections of Addo Elephant National Park, South Africa, namely Addo and Nyathi. These sections were separated by a public road, and the numbers of elephants, predators and tourists were higher in Addo. Faecal samples (n = 231) were collected (from July 2007 to November 2010) from known individuals and analysed for progestagen and androgen metabolite (FPM and FAM, respectively) concentrations. As biotic factors could impact reproduction, …
Ovarian Cycle Activity Varies With Respect To Age And Social Status In Free-Ranging Elephants In Addo Elephant National Park, South Africa, Elizabeth Freeman, Jordana Meyer, Sarah Putman, Bruce A. Schulte, Janine Brown
Ovarian Cycle Activity Varies With Respect To Age And Social Status In Free-Ranging Elephants In Addo Elephant National Park, South Africa, Elizabeth Freeman, Jordana Meyer, Sarah Putman, Bruce A. Schulte, Janine Brown

Free-ranging African elephants live in a fission–fusion society, at the centre of which is the matriarch. Matriarchs are generally older females that guide their families to resources and co-ordinate group defense. While much is known about elephant society, knowledge is generally lacking about how age affects the physiology of wild elephants. Investigation of the ovarian activity of free-ranging elephants could provide insight into the reproductive ageing process, with implications for population management. Faecal samples were collected from 46 individuals ranging in age from 14 to 60 years for a 2-year period, and progestagen metabolite analyses were used to examine relationships …
