Diet And Nutrition Of Lemurs In The Lean Season, Santiago Cassalett
Diet And Nutrition Of Lemurs In The Lean Season, Santiago Cassalett
Dissertations, Theses, and Capstone Projects
Animals must navigate complex food and nutrient environments that are constantly in flux to obtain the macro and micronutrients necessary for their growth, reproduction, and survival. The nutritional needs of animals also vary over the life course, further complicating the search for adequate foods and the nutrients within them. The hypervariable and unpredictable environment of Madagascar creates a complex nutrient landscape for lemurs in particular because they are subject to large fluctuations in food availability. These fluctuations are thought to create extreme periods of nutritional stress during the dry season (known as the lean season) for lemurs. In response, lemurs …

Dietary Development And Nutritional Ontogeny In Gorilla Beringei : A Multi-Layered, -Omics Approach, Emma C. Cancelliere
Dissertations, Theses, and Capstone Projects
In species who consume folivorous diets, immature individuals must contend with the challenges of extracting nutrients from fibrous foods before dietary adaptations and strategies are fully developed. Additionally, immatures have distinct nutritional needs to support their stage-specific metabolic and biophysiological requirements. To meet these stage-specific needs, while constrained by underdeveloped feeding strategies and digestive capacities, immatures may adopt distinct diets better suited to their specific developmental context. However, where dietary modification is constrained by low dietary diversity or landscape homogeneity, it is unclear how immature individuals compensate through alternative strategies. In turn, little is known about the nutritional and life …
The Functional Morphology Of Ingestion In The Platyrrhine Sclerocarpic Harvesters (Platyrrhini, Primates), Zachary Stoffel Klukkert
The Functional Morphology Of Ingestion In The Platyrrhine Sclerocarpic Harvesters (Platyrrhini, Primates), Zachary Stoffel Klukkert
Dissertations, Theses, and Capstone Projects
The identification of anatomical correlates of diet and feeding behavior in nonhuman primates is an important area of research in biological anthropology. The morphology of the jaws and teeth reflects the phylogeny and adaptations that distinguish taxa and their different ecological niches. Studying the form-function relationships of jaws and teeth in modern species provides a framework for interpreting the diets of extinct species and for inferring the ecological pressures that may have contributed to the evolutionary diversification of primate craniodental morphology. Previous work on modeling primate jaw mechanics has focused largely on the functional context of a closed jaw. Little …
The Morphology And Evolution Of The Primate Brachial Plexus, Brian M. Shearer
The Morphology And Evolution Of The Primate Brachial Plexus, Brian M. Shearer
Dissertations, Theses, and Capstone Projects
Primate evolutionary history is inexorably linked to the evolution of a broad array of locomotor adaptations that have facilitated the clade’s invasion of new niches. Researchers studying the evolution of primates and of their individual locomotor adaptations have traditionally relied on bony morphology – a practical choice given the virtual non-existence of any other type of tissue in the fossil record. However, this focus downplays the potential importance of the many other structures involved in locomotion, such as muscle, cartilage, and neural tissue, which may each be influenced by separate selective forces because of their different roles in facilitating movement. …
