Investigating the Applicability of Information Foraging Theory to Mobile Web Browsing
… evaluation and have increased its parent theory's (Information Foraging theory) credibility in the HCI community. These studies have, directly and indirectly, found significant correlations between good information scent and good usability. We would like to investigate its application to …

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 …

Examining financial puzzles from an evolutionary perspective
… applications from risk-sensitive optimal foraging theory, and the cheater detection hypothesis. Next we introduce some of the most-researched puzzles in the finance literature. Examples include overreaction, loss aversion, and the equity premium puzzle. Following this, we discuss …

Fine-Scale Foraging Behavior of Humpback Whales Megaptera novaeangliae in the Near-Shore Waters of the Western Antarctic Peninsula
… tools were used to examine the fine-scale foraging behaviors of humpback whales (Megaptera novaeangliae) in the coastal waters of the Western Antarctic Peninsula during the austral autumn of 2009 and 2010. Discrete feeding events (i.e., lunges) were inferred from the biologging records of …

A Mathematical Study of Purchasing Airline Tickets
We have sought to apply ideas from foraging theory to the purchase of airline tickets from competing websites in an online shopping environment. We explore how consumers might distribute themselves among websites and different tickets dependent on parameters such as price of ticket, number of …

Exploring Usage of Web Resources Through a Model of API Learning
… API learning process, drawing from information foraging theory, cognitive load theory, and external memory research. We ran an exploratory empirical user study in which participants performed a programming task using the React API with the goal of validating and refining this model. Our results …

Risk-Sensitive Foraging in Humans Budgeting Time: Correlated with Real-World Financial Situation
Foraging theory has been studied extensively in non-human animals. Using models developed through animal-study, researchers have recently begun to examine how humans make decisions with regard to resource-expenditure. Using a computer-based task, the proposed study investigated risk-sensitive …

Oystercatchers and cockles : a predatory-prey study
… increased with their size. According to optimal foraging theory, these larger ones should therefore have been preferred, and this proved to be so. The rate at which oystercatchers ate cockles followed a type II functional response. The plateau was not caused solely by handling time, nor were …

Factors Associated with Space Use and Reproductive Success of American Kestrels in Northern Virginia, USA
… 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 reproductive outcomes. …

ClickTrails: Enhancing Web Navigation with Usage-Based Stylization of Clicked Web Page Elements
… Drawing inspiration from concepts in information foraging theory, this thesis investigates methods to capture and visualize the typically unseen traversals made by users in the online domain as a method of improving the information scent of web pages. We introduce ClickTrails, a browser extension …

The Cost of Capturing Prey: Measuring Largemouth Bass Foraging Activity Using Glycolytic Enzymes (Lactate Dehydrogenase)
<p>Optimal foraging theory predicts that predators choose prey based on size, morphology, and behavior that maximizes the net energy gained per time spent foraging. For prey choice to be optimal, the ratio of energy gained to energy expended should be maximized. Activity costs associated with …

A RATE COMPARISON MODEL OF CONCURRENT SCHEDULE PERFORMANCE
… model of concurrent schedule performance and foraging is proposed. The model is a molecular equalizing theory of matching, based on results from optimal foraging theory and corresponding data from behavioral ecology. It state that animals leave one concurrent alternative for another whenever …

Consumption of Content on the Web: An Ecologically Inspired Perspective
… data mining and machine learning methods with theory from cognitive science. In particular, I draw inspiration from information foraging theory (and the earlier work on animal foraging on which it is based) and the ecological rationality research program. The three principal research questions …

A framework for understanding user interaction with content-based image retrieval: model, interface and users
… user types. Accordingly, based on Information Foraging Theory, we further propose a user classification model along three user interaction dimensions: information goals (I), search strategies (S) and evaluation thresholds (E) of users. To our best knowledge, this is the first principled user …

The effects of individual-level differences in metabolic rate on foraging behavior and life history traits in honeybees
… rate and life history is primarily mediated via foraging, which shapes the energy acquisition patterns of an individual. This predicts that individuals with different metabolic rates likely vary in their foraging strategies, although such links have rarely been empirically investigated in the …

Investigations of the Trophic Relationships, Feeding Ecology and Feeding Behavior of Larval Spot, <i>Leiostomus Xanthurus</i> Lacepede, and Atlantic Croaker, <i>Micropogonias Undulatus</i> (Linnaeus) (Pisces:Sciaenidae)
… in accordance with predictions made by optimal foraging theory and two other food selection models.</p> <p>The feeding incidence of three age classes of Leiostomus xanthurus, on the rotifer Brachionus plicatilis, was investigated under six different spectral regimes (red, yellow, green, blue and …

Host use and foraging in the parasitic plant Cuscuta subinclusa.
Foraging theory predicts active responses by organisms upon encounter with a resource, as opposed to the passive responses of differential survivorship and growth. Stems of the parasitic plant Cuscuta subinclusa invest in resource acquisition (coil) relative to host quality in a way predicted by …

The role of stochastic resonance and physical constraints in the evolution of foraging strategy
… study of the optimization of this process: foraging within a single, finite food patch for a limited amount of time. The work is an example of the computational algorithms of statistical physics being applied to the ecological field of foraging behavior. The analysis begins with an …
