Investigating a Renewable-Resource-Targeting Mobile Aquaculture System Using Route Optimization Based on Optimal Foraging Theory

open access: yesJournal of Marine Science and Engineering, 2023
Aquaculture systems require careful consideration of location, which determines water conditions, pollution impacts, and hazardous conditions. Mobility may be able to address these factors while also supporting the targeting of renewable energy sources ...

Shifting Deer Hunting Strategies as a Result of Environmental Changes along the Little and Great Miami Rivers of Southwest Ohio and Southeast Indiana [PDF]

open access: yes, 2020
This study analyzes white-tailed deer (Odocoileus virginianus) remains from five Fort Ancient archaeological sites along the Little and Great Miami Rivers of southwest Ohio and southeast Indiana to compare how the combination of varying ecologies ...

A marker of biological ageing predicts adult risk preference in European starlings, Sturnus vulgaris [PDF]

open access: yes, 2018
Why are some individuals more prone to gamble than others? Animals often show preferences between 2 foraging options with the same mean reward but different degrees of variability in the reward, and such risk preferences vary between individuals ...

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

Leave or stay? Video-logger revealed foraging efficiency of humpback whales under temporal change in prey density.

open access: yesPLoS ONE, 2019
Central place foraging theory (CPF) has been used to predict the optimal patch residence time for air-breathing marine predators in response to patch quality.

The topography of the environment alters the optimal search strategy for active particles [PDF]

open access: yes, 2017
In environments with scarce resources, adopting the right search strategy can make the difference between succeeding and failing, even between life and death.

Animal research in the UK: Regulation, implementation, welfare and development of new approach methodologies

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Scientific research with animals in the UK is regulated by the Animals (Scientific Procedures) Act 1986 with the National Centre for the Replacement, Refinement and Reduction of Animals in Research providing support for best practice and facilitating development of new approach methodologies.

Diving seabirds share foraging space and time within and among species

open access: yesEcosphere, 2010
Ecological theory predicts that animals with similar foraging strategies should not be able to co‐exist without segregating either in space, time or diet. In communities, intra‐specific competition is thought to be more intense than the competition among

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.
