The Use of Sound Recorders to Remotely Measure Grass Intake Behaviour in Horses

open access: yesAnimals
Visual observation to record grass intake is time-consuming and labour-intensive. Technological methods, such as activity monitors, have been used but only record head position.

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

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

Rhizodeposition Drives One Third of Belowground Carbon Input in Agroecosystems

open access: yesAdvanced Science, EarlyView.
This study quantifies photosynthesized C allocation in the plant–soil system across six crop types: barley, wheat, maize, rice, legumes and grasses. It reports C partitioning into shoot respiration, shoot‐C, root‐C, net rhizodeposition and root‐derived CO2, providing standardized percentage averages and GPP‐derived absolute values as a robust baseline ...

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

open access: yesAdvanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland

open access: yesAdvanced Science, EarlyView.
In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.

Hypothalamic POMC Neurons Gate the Fear‐Feeding Trade‐Off

open access: yesAdvanced Science, EarlyView.
Hungry animals must continually arbitrate between feeding and defensive behaviors when confronted with potential threats. We show that hypothalamic POMC neurons engage CRH‐expressing stress circuits and downstream hormonal responses to coordinate this behavioral selection between competing behaviors.

Current frontiers in the passive acoustic monitoring of bats

open access: yesMethods in Ecology and Evolution
Passive acoustic monitoring of bats is used in a growing number of studies in applied and basic research, from local to global scales. Despite the publication of good‐practice recommendations, several unsettled debates persist about the possibilities and

Anticipatory Behavior of the Clonal Plant Fragaria vesca

open access: yesFrontiers in Plant Science, 2018
Active foraging for patchy resources is a crucial feature of many clonal plant species. It has been recently shown that plants’ foraging for resources can be facilitated by anticipatory behavior via association of resource position with other ...

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.
