Floor Substrate Preferences of Chickens: A Meta-Analysis

open access: yesFrontiers in Veterinary Science, 2020
Environmental enrichment promotes sensory and motor stimulation for species-typical behaviors, which in turn enhance animal well-being. For farmed Galliformes, housing systems often limit enrichment to bedding and litter, that simultaneously act as ...

Energetic synchrony throughout the non‐breeding season in common guillemots from four colonies

open access: yesJournal of Avian Biology, 2023
The non‐breeding season presents significant energetic challenges to birds that breed in temperate or polar regions, with clear implications for population dynamics.

Optimal L\'{e}vy-flight foraging in a finite landscape

open access: yes, 2014
We present a simple model to study L\'{e}vy-flight foraging in a finite landscape with countable targets. In our approach, foraging is a step-based exploratory random search process with a power-law step-size distribution $P(l) \propto l^{-\mu}$. We find

Does foraging efficiency vary with colony size in the fairy martin Petrochelidon ariel? [PDF]

open access: yes, 2009
Colonial breeding occurs in a wide range of taxa, however the advantages promoting its evolution and maintenance remain poorly understood. In many avian species, breeding colonies vary by several orders of magnitude and one approach to investigating the ...

Foraging activity by the southern brown bandicoot (Isoodon obesulus) as a mechanism for soil turnover [PDF]

open access: yes, 2012
Mammals that forage for food by biopedturbation can alter the biotic and abiotic characteristics of their habitat, influencing ecosystem structure and function.

Information Exchange Design Patterns for Robot Swarm Foraging and Their Application in Robot Control Algorithms

open access: yesFrontiers in Robotics and AI, 2018
In swarm robotics, a design pattern provides high-level guidelines for the implementation of a particular robot behaviour and describes its impact on swarm performance.

Optimal random search using limited spatial memory [PDF]

open access: yesRoyal Society Open Science, 2018
Lévy walks are known to be efficient movements because Lévy walkers search wide areas while restricting returns to previously visited sites. A self-avoiding walk (SAW) is a series of moves on a lattice that visit the same place only once.

Home range and habitat use by Kemp's Ridley turtles in West-Central Florida [PDF]

open access: yes, 2003
The Kemp's ridley turtle (Lepidochelys kempii) is an endangered species whose recovery depends in part on the identification and protection of required habitats.

Density-dependent, central-place foraging in a grazing herbivore: competition and tradeoffs in time allocation near water [PDF]

open access: yes, 2015
Optimal foraging theory addresses one of the core challenges of ecology: predicting the distribution and abundance of species. Tests of hypotheses of optimal foraging, however, often focus on a single conceptual model rather than drawing upon the ...
