Managing Sociality of a Captive Female Bornean Orangutan from Breeding to Post-partum at The Smithsonian\u27s National Zoo

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. Post-partum socialization and proximity data suggest a shift in female affiliation. The presence of another female with maternal experience may be beneficial to the rearing of new offspring. These results can help guide socialization management for pregnant captive orangutans to improve breeding outcomes

Comparative morphological study on the shape variance of the scapula in extant Cercopithecidae

Morphological variation in forelimb bones has been tied to substrate use in Cercopithecidae. Studies of the distal humerus and proximal ulna (Rector et al., 2018) suggest that African and Asian monkeys’ locomotor repertoires can be distinguished through analysis of variation of the elbow joint. Given that the scapula may be directly involved in weight-bearing during locomotion - similar to the elbow - the relationship between morphological variation and arboreality in the glenoid cavity, acromion, and coracoid process may be analogous. Using a Microscribe, 25 landmarks were collected to capture the shape of the scapula from a sample of 50+ extant Cercopithecidae. Each species was placed in a locomotor category including ground quadrupedalism, branch quadrupedalism, arm-swinging, and branch quadrupedalism, and branch and ground quadrupedalism based on their primary locomotor strategy during traveling. Variation was analyzed using 3D geometric morphometric PCA, PGLs, and phylogenetic ANOVAs to determine if differential substrate use can be identified through analysis of shape variation in the scapulae of Cercopithecidae. Results suggest that scapular morphology is more variable in branch quadrupedal cercopithecids than ground quadrupedal ones. However, variation in the scapula can be used to successfully differentiate ground quadrupeds and branch quadrupeds in modern Cercopithecidae. As a valuable factor in the ecology of these primates, this locomotor behavior contributes information on niche differentiation, resource competition, and community organization in living and fossil primates.https://scholarscompass.vcu.edu/gradposters/1050/thumbnail.jp

Colobinae evolution: Using GIS to map the distribution of leaf monkeys across Southeast Asia over time

The Colobinae, or leaf monkeys, are distributed geographically across Africa and Asia. Colobinae are specialized arborealists and leaf eaters with sacculated stomachs, sheering teeth, reduced thumbs, and very mobile shoulders. Colobinae diverged ~10.9 million year ago (Ma) from the Cercopithecidae in Africa, and Asian colobines appear in the fossil record in the late Miocene ~8.5 Ma. However, an incomplete fossil record means little is known about the evolutionary pressures that led to Asian colobine migration and diversification. Here, we use recent fossil discoveries and geospatial information to develop hypotheses about how geographic barriers played direct roles in Asian colobine evolution. Using ArcGIS, we plotted Miocene-epoch to Pleistocene-epoch fossil Colobinae collection sites with overlapping geospatial information including geographic barriers that may have influenced species distribution like the Himalayas and the Hengduan Mountains. We also included extant species’ presence, distributions, and species diversity to assess patterns of distribution over time. Data from each epoch were compared to track species distribution over time. Results suggest that combining fossil data, extant species’ distributions, and biogeographically relevant geospatial elements provides some parameters for where and when Colobine adaptions were selected for. For example, cold climate adaptions in certain Asian Colobines, especially Rhinopithecus, are not recent and have shaped how that genus is distributed today. These parameters can support powerful hypothesis building about the evolutionary histories of extant species adapting behaviorally and anatomically to densely forested South East Asia.https://scholarscompass.vcu.edu/gradposters/1134/thumbnail.jp

` Adding value to the fish! ´ Business Strategies in Fish Farming and Small-Scale Fishery

The development of values-based supply chains for fish and fish products from fisheries and aquaculture is a strategy to add value to the fish. This benefit refers to the double meaning of ‘value’; premium prices for high-value products and at the same time, the incorporation of environmental, social, cultural or ethical values based on a sustainable use of resources. Although small-scale fish production and fisheries have a long tradition in many regions of the European Union, fishermen and fish farmers face strong competition with industrialized fishery fleets as well as imports from lowcosts aquaculture. At the same time, European consumer surveys prove evidence that a consumers show an overaverage Willingness to Pay (WTP) for fish produced locally and according to sustainability standards. With this paper, we aim to identify and discuss fish farmers’ and fishermen’s strategies ensuring the viability of their businesses by adding value to their fish utilizing this so far often unused market potential. Four case studies serve as the basis for the analysis. The German case studies examined traditional carp pond farming in Franconia and recirculation aquaculture systems in northern Germany. The Italian case studies focus on saline aquaculture (marine and on-shore) in Tuscany and mussel farming (inshore) in the Emilia-Romagna region. The English, Italian and Greek study cases analysed the situation of small-scale coastal fisheries in Cornwall, Tuscany and the Kavala region

Data from: On the use of climate covariates in aquatic species distribution models: are we at risk of throwing the baby out?

Species distribution models (SDMs) in river ecosystems can incorporate climate information by using air temperature and precipitation as surrogate measures of instream conditions or by using independent models of water temperature and hydrology to link climate to instream habitat. The latter approach is preferable but constrained by the logistical burden of developing water temperature and hydrology models. We therefore assessed whether regional scale, freshwater SDM predictions are fundamentally different when climate data versus instream temperature and hydrology are used as covariates. Maximum Entropy (MaxEnt) SDMs were built for 15 freshwater fishes using one of two covariate sets: (1) air temperature and precipitation (climate variables) in combination with physical habitat variables; or (2) water temperature, hydrology (instream variables) and physical habitat. Three procedures were then used to compare results from climate vs. instream models. First, equivalence tests assessed average pairwise differences (site-specific comparisons throughout each species’ range) among climate and instream models. Second, ‘congruence’ tests determined how often the same stream segments were assigned high habitat suitability by climate and instream models. Third, Schoener’s D and Warren’s I niche overlap statistics quantified range-wide similarity in predicted habitat suitability values from climate vs. instream models. Equivalence tests revealed small, pairwise differences in habitat suitability between climate and instream models (mean pairwise differences in MaxEnt raw scores for all species -4). Congruence tests showed a strong tendency for climate and instream models to predict high habitat suitability at the same stream segments (median congruence = 68%). D and I statistics reflected a high margin of overlap among climate and instream models (median D = 0.78, median I = 0.96). Overall, we found little support for the hypothesis that SDM predictions are fundamentally different when climate versus instream covariates are used to model fish species’ distributions at the scale of the Columbia Basin

Integrating Anthropology and Biology: Comparing Success Rates and Learning Outcomes for University-Level Human Evolution Courses

Curriculum development in biological anthropology requires instructors to generate learning outcomes for both anthropology and biology majors. However, these students have substantially different backgrounds. Anthropology curricula do not always require biology prerequisites, and many instructors are concerned that anthropology majors may not be as prepared to learn biology content. As bioanthropological research increasingly relies on genetics and phylogenomics, a strong emphasis needs to be put on integrating biological content into anthropology courses. The core-level “Human Evolution” course at Virginia Commonwealth University is taught under an anthropology rubric. The course is divided into four primary units: two units cover topics that are also explored in lower-level biology courses (e.g., DNA inheritance) and two units focus on paleoanthropological topics (e.g., hominin taxonomy). Here, we compare results of course assessments between anthropology and biology majors across four semesters to determine whether students in the two majors performed differently on units with “biology” content versus “anthropology” content. A series of statistical tests reveal that overall, anthropology and biology majors are earning comparable final grades in the course. Additionally, when assessment results for units with differing content are contrasted, anthropology and biology majors scored comparably on “anthropology” content units. However, in some semesters, biology majors scored statistically significantly better in the “biology” units than in “anthropology” units, and in one semester, anthropology majors scored statistically significantly better than biology majors in “biology” content. These results suggest that it is biology majors, rather than anthropology majors, who are deficient in an integrated bioanthropological perspective. We recommend that anthropology and biology departments consider introducing an integrated curriculum that is interdisciplinary rather than multidisciplinary by design.
