Managing Sociality Of A Captive Female Bornean Orangutan From Breeding To Post-Partum At The Smithsonian's National Zoo, Marie Vergamini
Theses and Dissertations
The Association of Zoos and Aquariums’ Orangutan Species Survival Plan® aims to maintain 100 Bornean orangutans (Pongo pygmaeus) in captivity. Because investment in breeding these lineages is high, properly managing sociality of potential mothers is essential. This study assessed how behaviors of a captive breeding female at the Smithsonian’s National Zoo changed from pre-gestation through the offspring’s sixth month of age to improve breeding recommendations.
The infant Bornean orangutan was born September 2016. Results indicate that during breeding, the mother socialized most with two adult females. During pregnancy, the pregnant female socialized in less energy-consuming ways, i.e. grooming. …
Homo Heidelbergensis: The Tool To Our Success, Alexander Burkard
Homo Heidelbergensis: The Tool To Our Success, Alexander Burkard
AUCTUS: The Journal of Undergraduate Research and Creative Scholarship
Homo heidelbergensis, a physiological variant of the species Homo sapien, is an extinct species that existed in both Europe and parts of Asia from 700,000 years ago to roughly 300,000 years ago (carbon dating). This “subspecies” of Homo sapiens, as it is formally classified, is a direct ancestor of anatomically modern humans, and is understood to have many of the same physiological characteristics as those of anatomically modern humans while still expressing many of the same physiological attributes of Homo erectus, an earlier human ancestor. Since Homo heidelbergensis represents attributes of both species, it has therefore earned the classification as …
Dietary Adaptations And Intra- And Interspecific Variation In Dental Occlusal Shape In Hominin And Non-Hominin Primates, Kelsey O'Neill
Dietary Adaptations And Intra- And Interspecific Variation In Dental Occlusal Shape In Hominin And Non-Hominin Primates, Kelsey O'Neill
Theses and Dissertations
Dental morphology and tooth shape have been used to recreate the
dietary adaptations for extinct species, and thus dental variation can provide
information on the relationship between fossil species and their
paleoenvironments. Variation in living species with known behaviors can provide
a baseline for interpreting morphology, and behavior, in the fossil record.
Tooth occlusal surface outlines in hominins and non-hominin primates, and other
mammals, have been used for assessments of taxonomic significance, with
variability often considered as being primarily phylogenetic. Few studies have
attempted to assess how diet might influence the pattern of variability in closely
related species. Here the …
