Adaptive Lévy processes and area-restricted search in human foraging [PDF]

, 2013
A considerable amount of research has claimed that animals’ foraging behaviors display movement lengths with power-law distributed tails, characteristic of Lévy flights and Lévy walks.

Teaching Genetic Linkage and Multiple Crossovers with Sets of Cards as Chromosomes

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.

Test of theory of foraging mode: Goldcrests, Regulus regulus, forage by high‐yield, energy‐expensive hovering flight when food is abundant but use low‐yield, low‐cost methods when food is scarce

Ecology and Evolution, 2021
Here, I describe foraging behavior of goldcrests, Regulus regulus, based on eight years of field observation in a coniferous forest dominated by Norway spruce Picea abies in southwestern Sweden.

Feeding ecology of a highly aerial bird during its long breeding season

Avian Research, 2023
Pallid Swifts (Apus pallidus), as other swifts, are birds extremely adapted to an aerial lifestyle, showing unique adaptations that allow them to fly almost continuously.

The application of foraging theory to the information searching behaviour of general practitioners

BMC Family Practice, 2011
Background General Practitioners (GPs) employ strategies to identify and retrieve medical evidence for clinical decision making which take workload and time constraints into account.

Creative foraging: An experimental paradigm for studying exploration and discovery. [PDF]

PLoS ONE, 2017
Creative exploration is central to science, art and cognitive development. However, research on creative exploration is limited by a lack of high-resolution automated paradigms.

Trail complexity and foraged plants for the leaf-cutting ant Atta sexdens (Hymenoptera: Formicidae) in a caatinga area of Bahia

Zoologia (Curitiba)
Leaf-cutting ants (LCAs; Atta, Acromyrmex, and Amoimyrmex) are key herbivores in Neotropical ecosystems, preferentially harvesting leaves from palatable plant species such as pioneers and colonizers.

Foraging behaviour of Brazilian riverine and coastal fishers: How much is explained by the optimal foraging theory?

Conservation & Society, 2011
Optimal Foraging Theory (OFT) is here applied to analyse the foraging behaviour of Brazilian artisanal fishers of the Atlantic coast (Itacuruçá and São Paulo Bagre villages) and of the inland Amazonian region (Jarauá and Ebenezer villages).

How Plant Toxins Cause Early Larval Mortality in Herbivorous Insects: An Explanation by Modeling the Net Energy Curve

Toxins
Plants store chemical defenses that act as toxins against herbivores, such as toxic isothiocyanates (ITCs) in Brassica plants, hydrolyzed from glucosinolate (GLS) precursors.

Images as proximity sensors : the incidence of conspecific foraging in Antarctic fur seals [PDF]

, 2015
Background: Although there have been recent advances in the development of animal-attached ‘proximity’ tags to remotely record the interactions of multiple individuals, the efficacy of these devices depends on the instrumentation of sufficient animals ...
