Traces of a Neonicotinoid Induce Precocious Foraging and Reduce Foraging Performance in Honey Bees.

open access: yesEnvironmental Science and Technology, 2019
There is increasing worldwide concern about the impacts of pesticide residues on honey bees and bee colony survival, but how sublethal effects of pesticides on bees might cause colony failure remains highly controversial, with field data giving very ...

Starvation Dynamics of a Greedy Forager [PDF]

open access: yesJ. Stat. Mech. 073213 (2017), 2017
We investigate the dynamics of a greedy forager that moves by random walking in an environment where each site initially contains one unit of food. Upon encountering a food-containing site, the forager eats all the food there and can subsequently hop an additional $\mathcal{S}$ steps without food before starving to death.

Feeding and foraging ecology of Trindade petrels Pterodroma arminjoniana during the breeding period in the South Atlantic Ocean [PDF]

open access: yes, 2017
Seabirds breeding in tropical environments experience high energetic demands, when foraging in an oligotrophic environment. The globally threatened Trindade petrel Pterodroma arminjoniana has its largest colony in Trindade Island (20°30′S–29°19′W) inside

Fidelity to foraging sites after long migrations.

open access: yesJournal of Animal Ecology, 2019
Patterns of animal movement associated with foraging lie at the heart of many ecological studies and often animals face decisions of staying in an environment they know, versus relocating to new sites.

Association patterns and foraging behaviour in natural and artificial guppy shoals [PDF]

open access: yes, 2008
Animal groups are often nonrandom assemblages of individuals that tend to be assorted by factors such as sex, body size, relatedness and familiarity.

Root morphology and mycorrhizal symbioses together shape nutrient foraging strategies of temperate trees

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance Plant growth requires acquisition of soil nutrients in a patchy environment. Nutrient patches may be actively foraged by symbioses comprising roots and mycorrhizal fungi. Here, we show that thicker root tree species (e.g., tulip poplar, pine)

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.

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.

Understanding the ontogeny of foraging behaviour: insights from combining marine predator bio-logging with satellite-derived oceanography in hidden Markov models

open access: yesJournal of the Royal Society Interface, 2018
The development of foraging strategies that enable juveniles to efficiently identify and exploit predictable habitat features is critical for survival and long-term fitness.
