Testing optimal foraging theory in a penguin–krill system [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2014
Food is heterogeneously distributed in nature, and understanding how animals search for and exploit food patches is a fundamental challenge in ecology. The classic marginal value theorem (MVT) formulates optimal patch residence time in response to patch quality.

Optimal foraging theory and niche-construction theory do not stand in opposition [PDF]

Proceedings of the National Academy of Sciences, 2015
In a recent paper, Zeder (1) outlines core archaeological questions in domestication research, highlighting the importance of defining the process, when it happened, and why it happened in various global contexts. Importantly, she emphasizes the utility of separating initial domestication from intensive agricultural practices, pointing out that often ...

Promoting Quantitative Skills in Introductory Classes Using Optimal Foraging Theory and a Model-Assisted Activity [PDF]

Journal of Microbiology & Biology Education, 2017
TMathematical models help students identify and understand underlying scientific patterns, while improving and reinforcing quantitative skills. However, they are often omitted from introductory undergraduate science classes.

A New Application for the Optimal Foraging Theory: The Extraction of Medicinal Plants [PDF]

Evidence-Based Complementary and Alternative Medicine, 2012
The Optimal Foraging Theory was used to identify possible patterns in bark extraction and the selective cutting ofAnadenanthera colubrina(Angico), a medicinal plant. The hypotheses were built on two approaches: selection of collection place and bark exploitation occurrence in only one of these resource areas.

Experience-based optimal foraging on planktonic prey in Baikal seals [PDF]

Movement Ecology
Background Understanding how predatory animals efficiently locate prey with limited knowledge of its location is challenging. Optimal foraging theory suggests that animals improve their food intake through experience-based adjustments of search patterns.

Water Level Regulation Regime Shifts Drive Divergent Foraging Habitat Use by Wintering Hooded Cranes (Grus monacha) in Shallow Gate‐controlled Lakes of the Yangtze Floodplain [PDF]

Ecology and Evolution
Habitat use is fundamental for animal survival at key life history stages. Understanding how changes in foraging habitat conditions modulate habitat‐use patterns is critical in wildlife conservation.

Mechanism of Dietary Variation of Grazing Yaks on Tibetan Plateau: The Role of Seasonal Heterogeneity of Resources [PDF]

Ecology and Evolution
Diet composition is a crucial yet understudied, dimension of animal ecology, with seasonal dietary shifts being a key factor in the population dynamics of large herbivores.

An Experimental Test of Central Place Foraging Theory in a Cooperatively Breeding Bird [PDF]

Ecology and Evolution
Central place foraging, whereby individuals are constrained in their foraging by their need to return to a central place, is common in nesting birds. A key prediction of the central place foraging theory models developed by Orians and Pearson is that as ...

Beyond Depression? A Review of the Optimal Foraging Theory Literature in Zooarchaeology and Archaeobotany

Ethnobiology Letters, 2017
The use of optimal foraging theory in archaeology has been criticized for focusing heavily on “negative” human-environmental interactions, particularly anthropogenic resource depression, in which prey populations are reduced by foragers’ own foraging ...
