If Rocks Could Talk: Using Central Place Foraging Theory in Lithic Production and Utilization Research
This research addresses microeconomic decision making during the Fur-Trade Occupation at Housepit 54 of the Bridge River Site. Specifically, it addresses the lithic production in regard to field processing and technological investment at the site. Field processing considers the importance of cost …

Evolving Efficient Foraging Behavior in Biologically-Inspired Robot Swarms
… new worlds as we seek to better understand our place in the Universe. Because of the inherent dangers of human spaceflight, we often send robots as surrogate explorers, controlled from millions of miles away by teams of capable rover drivers here on Earth. As technology continues to advance, …

Factors Associated with Space Use and Reproductive Success of American Kestrels in Northern Virginia, USA
… parental roles, local resource availability, and central-place foraging theory as a framework for linking movement to reproductive success. From 2021 to 2024, I used GPS loggers to track 69 kestrels (male = 27, female = 42) in northern Virginia and monitored nesting attempts (n = 48) for …

Plasticity and partitioning of foraging behaviour among and within sympatric Pygocelis penguin populations
Central-place foragers, such as breeding seabirds, need to adjust their foraging behaviours in response to the growth and development of their offspring. As a result, they need to return to their nests regularly. These breeding constraints limit their foraging ranges. In the Southern Ocean, …

The Ant and the Trap: Evolution of Ant-Inspired Obstacle Avoidance in a Multi-Agent Robotic System
… movements and stygmergic trails into the iAnt Central Place Foraging Algorithm (CPFA) could result in robot behaviors suited to navigating obstacle-filled environments. The result is a modification of the CPFA to include pheromone trails, CPFA-Trails or CPFAT. This thesis first demonstrates the …

Large mammal resource depression and agricultural intensification: an empirical test in the Mimbres Valley, New Mexico
… has tested the proposition that wild resource foraging efficiency declined in any archaeological case in which there is evidence that agriculture became more important. This dissertation is a study of hunting and farming in the Mimbres Valley of southwestern New Mexico that is directed at …

Late Holocene Logistical and Residential Settlement in Interior Santa Rosa Island, California: A Comparative Analysis of Four Rockshelter Sites
… from the perspective of the Diet Breadth and Central Place Foraging (CPF) models from Human Behavioral Ecology (HBE). To test each hypothesis, I use four lines of evidence: radiometric dating (radiocarbon), faunal analysis (primarily marine fauna), stable isotopic data from Mytilus …

African penguin (Spheniscus demersus) distribution during the non-breeding season : preparation for, and recovery from, a moulting fast
… penguin during the non-breeding season. As foraging success during this period is critical to adult survival, this project explores their dispersal patterns, as well as the degree of overlap with commercial purse-seine fisheries which target the same prey. African penguins from two colonies …

Social life-styles in caterpillars: Behavioral mechanisms and ecological consequences
… neustria. In addition to these tent building, central-place foraging species a fourth, non-tent building nomadic butterfly species, Araschnia levana (Nymphalidae) was also studied. Caterpillars of E. lanestris are behavioral thermoregulators. In the laboratory (i.e. in the absence of solar …

OPTIMAL GROUP SIZE IN HUMANS: AN EXPERIMENTAL TEST OF THE SIMPLE PER CAPITA MAXIMIZATION MODEL
… for predicting optimal group sizes in social foraging contexts. Participants engaged in a social foraging task where they chose to forage for points exchangeable for lottery prizes either alone or in a group that has agreed to pool and share all resources equally. In Experiment 1, groups …

The foraging ecology of the short-tailed shearwater puffinus tenuirostris.
… trophic interactions, resource requirements and foraging ecology of this wide ranging pelagic seabird. I studied the movement of adults during the short trip (ST) and long trip (LT) component of their dual foraging strategy to determine how they use their marine habitat. ST were primarily …

Foraging and Menstruation in the Hadza of Tanzania
… very similar resources, the Hadza maintain a foraging lifestyle characterised by a sexual division of labour. Studies of their foraging and food sharing habits serve as the foundation to numerous hypotheses of human behaviour and evolution. Data from the Hadza have featured heavily in debates …
