Understanding The Environmental And Genetic Influence On Fluctuating Asymmetry And Developmental Instability In Primates, Ashly N. Romero
Understanding The Environmental And Genetic Influence On Fluctuating Asymmetry And Developmental Instability In Primates, Ashly N. Romero
Graduate Theses and Dissertations
This dissertation explored the impact of environmental factors on the development and perpetuation of fluctuating asymmetry (FA) and sought to understand the role evolution may play in the FA exhibited in two primate populations: the free-ranging Cayo Santiago rhesus macaques (Macaca mulatta) and the Southwest National Primate Research Center olive baboons (Papio hamadryas anubis). Demographic, ontogenetic, secular, external, and genetic factors were examined. Specifically, this dissertation investigated FA over all ontogenetic stages, across decades, between sexes, in association with ecological catastrophes, and with tooth pathology to try and tease apart factors that may influence FA and developmental instability. This dissertation …
Canine Microwear In Relation To Diet In Sumatran Primates And African Great Apes, Putu Pujiantari
Canine Microwear In Relation To Diet In Sumatran Primates And African Great Apes, Putu Pujiantari
Graduate Theses and Dissertations
This thesis considers canine microwear in relation to diet in five Sumatran primates (Pongo abelii, Hylobates lar, Hylobates agilis, Presbytis thomasi, and Macaca fascicularis) and two African great apes (Pan paniscus and Pan troglodytes schweinfurthii) using both microwear texture analysis and microwear feature analysis techniques. Statistical results for texture analysis show that there are significant differences in scale of maximum and heterogeneity. This indicates that some species have large pits on their canine surfaces, having these dominated by deep features at coarse scale yet have a slight microwear heterogeneity. For feature analysis, all variables show statistically significant variation. Variance in …
