Interactive effects of body mass changes and species‐specific morphology on flight behavior of chick‐rearing Antarctic fulmarine petrels under diurnal wind patterns

open access: yesEcology and Evolution, 2021
For procellariiform seabirds, wind and morphology are crucial determinants of flight costs and flight speeds. During chick‐rearing, parental seabirds commute frequently to provision their chicks, and their body mass typically changes between outbound and

Comprehensive analysis of the circular RNA expression profile and circRNA–miRNA–mRNA network in the goat skin with divergent wool curvature

open access: yesAnimal Research and One Health, EarlyView., 2023
In our study, we conducted circRNA expression profiling of Zhongwei goat skin exhibiting divergent curvature wool phenotypes at two developmental stages using the RNA‐seq. Functional verification assay demonstrated that circRNA8782 regulated fibroblast proliferation.

Echolocation activity of harbour porpoises, Phocoena phocoena, shows seasonal artificial reef attraction despite elevated noise levels close to oil and gas platforms

open access: yesEcological Solutions and Evidence, 2021
Harbour porpoises frequently alter their behaviour in response to underwater sound from shipping, seismic surveys, drilling and marine renewables. Less well understood is the response of porpoises to sounds emitted from oil and gas (O&G) platforms during

Late Winter Foraging by Honeybees (Hymenoptera: Apidae) at Sapsucker Drill Holes [PDF]

open access: yes, 2017
Observations of Apis mellifera foraging at sapsucker drill holes were made during February 1988 in southwestern Virginia. Foraging bouts were dependent upon temperature; more bees visited drill holes when ambient temperatures exceeded 10oC. Honeybees did

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

On food composition and foraging ecology of the Western Yellow Wagtail (Motacilla flava) in Western Slovakia

open access: yesTichodroma, 2022
The Western Yellow Wagtail (Motacilla flava) is typical species of agricultural landscapes, where the food supply is significantly limited. The nestling diet composition and its foraging ecology are little known in the entire range. Therefore, we studied

Modality-specific attention in foraging bumblebees [PDF]

open access: yesRoyal Society Open Science, 2015
Attentional demands can prevent humans and other animals from performing multiple tasks simultaneously. Some studies, however, show that tasks presented in different sensory modalities (e.g. visual and auditory) can be processed simultaneously.

Foraging of pigs in outdoor areas (OK-Net Ecofeed Practice Abstract) [PDF]

open access: yes, 2020
• Root foraging crops, like Jerusalem artichokes or sugar beet (photo 1), can cover more than 80 % and 50 % of the energy requirements of pregnant sows and growing/finishing pigs, respectively.

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.

Genetic structure of annual ryegrass (Lolium multiflorum) populations estimated by RAPD Estrutura genética de populações de azevém anual (Lolium multiflorum) estimada por RAPD

open access: yesScientia Agricola, 2004
Annual ryegrass is a temperate climate annual foraging grass, grown mostly in the South of Brazil, especially in the state of Rio Grande do Sul. Despite its importance, little is known about its genetic diversity, both within and among the populations ...
