The reproductive ecology of the little-known Kinda baboon (Papio kindae)

PhD dissertation; New York University

For my PhD dissertation, I am studying the reproductive ecology of the little-known Kinda baboon at the Kasanka Baboon Project in Zambia. Kinda baboons are morphologically, genetically, and behaviorally distinct from other baboon species. I am interested in understanding their unique reproductive and life-history strategies in order to test different comparative models of evolutionary primatology.

I spent summer 2014 and 2015 in Zambia undertaking pilot research in Kafue and Kasanka National Parks in Zambia. My pilot research was supported from generous funds from the American Association of University Women and NSF IGERT. I am currently applying for grants with plans to return to Zambia in 2017.

My PhD advisor is James Higham, though I am also supervised by Cliff Jolly and Todd Disotell. This project is in collaboration with Anna Weyher and the Kasanka Baboon Project. 


Is the red facial coloration of male rhesus macaques (Macaca mulatta) under intra-sexual selection?

MA thesis; New York University; 2016

Male sexually selected traits can evolve under different selection mechanisms: armaments evolve via intrasexual selection, and ornaments usually via intersexual selection. The colorful signals found in many primates appear to be products of intrasexual selection as they typically indicate social status, like most mammalian armaments. This, however, is not true in male rhesus macaques; red facial coloration does not correlate with dominance rank and is attractive to females, suggesting it evolved primarily under intersexual selection. Nonetheless, males pay attention to other male’s facial coloration. For my MA thesis, I examined the role of facial coloration in free-ranging male rhesus macaques, to determine if this signal influences the outcome of agonistic male-male interactions, and is more strongly expressed in contexts generating intense competition. 

I was supervised by James Higham and worked in collaboration with Constance Dubuc and Alexander Georgiev.

We are currently turning my thesis into a manuscript. Our results were presented at ISBE in July 2016 and IPS/ASP in August 2016 (read abstract).


Osteological markers of cheek flanges in Mandrillus

2014-present; New York University 

A major challenge in paleoanthropology is reconstructing the behavioral strategies of extinct primates represented only by fossils. Canine size and estimates of body size are used to infer sexual dimorphism as a proxy of socio-sexual behavior; however, these are somewhat limited and other bony correlates of soft tissue sexual traits may be more informative. This study assesses the cheek flanges that characterize adult male drills but not closely related mandrills in an attempt to identify potential osteological markers that characterize this secondary sexual characteristic.

This project is supervised by Scott Williams and James Higham; we are currently in the process of expanding our dataset.

Preliminary results were presented at the 2015 American Association of Physical Anthropology annual conference: download our abstract here.


Sexual swelling symmetry, individual quality, and attractiveness in wild female olive baboons (Papio anubis)

Master's thesis; University of Roehampton; 2012

The sexual swellings that characterize many female papionin primates have been examined in relation to their function as a signal of reproductive quality or fertility. I measured the fluctuating asymmetry of the sexual swelling via photogrammetry and morphometric analyses to expand the assessment of this multicomponent signal to determine if it advertised female reproductive quality and/or was attractive to conspecifics.

I was supervised by Dr. Caroline Ross as part of the MRes in Primate Behaviour, Biology, and Conservation. My research took place at Gashaka-Gumti National Park in Nigeria.

Reproductive suppression in captive female cheetahs (Acinonyx jubatus)

Undergraduate research project; 2008

At the San Diego Zoo Institute for Conservation Research, I worked in the Behavioral Ecology division to understand the reproductive implications of social housing on captive female cheetahs. I used a combination of behavioral observations and hormone monitoring (measured non-invasively from fecal metabolites). We wanted to determine if group-housed cheetahs were reproductively suppressed in comparison to a solitary-housed cheetah, and if this relationship was mediated through social interactions.
 
I was supervised by Dr. Fred Bercovitch, Dr. Matt Anderson, and Corinne Pisacane. I was funded by a Summer Student Fellowship.
