Tradeoffs between brain and digestive tissues across elevations in Typhlomys daloushanensis: evidence for sexual dimorphism

open access: yesWildlife Biology, EarlyView.
To cope with highly stochastic and/or heterogeneous environmental conditions, animals must balance energy resource allocation across physiological processes. The digestive tract and brain exhibit structural variations under strong developmental and selective pressures that vary across environmental gradients both between and within species.

Morphological and Molecular Characterization of Eimeria saudiensis From Arabian Oryx (Oryx leucoryx) Held in Captivity in the Sultanate of Oman 阿曼苏丹国圈养阿拉伯羚羊 (Oryx leucoryx) 体内沙特艾美球虫 (Eimeria saudiensis) 的形态学与分子特征

open access: yesWildlife Letters, EarlyView.
Eimeria saudiensis represents a genus of apicomplexan parasites capable of inducing coccidiosis in Arabian oryx. Our research concentrated on the morphological and molecular investigation of Eimeria spp. in the captive oryx herd in Oman. The therapeutic and management practices employed at the Mammals Breeding Center were reassessed to diminish ...

Comparative Trends of Sociality Among Terrestrial Carnivores: A Multivariate Analysis 陆生食肉动物社会性的比较趋势:一项多变量分析

open access: yesWildlife Letters, EarlyView.
In this study we analyze the role of phylogeny, environment, and community structure on sociality. Using structural equation modeling (SEM) we aim to quantify the direct and indirect impacts of variables on behaviors including social grouping, reproduction, and space use among Carnivora species.

Lack of capture‐induced mortality of neonates associated with variation in handling protocols

open access: yesWildlife Society Bulletin, EarlyView.
We found that handling metrics (e.g., handling time, number of collectors, and age at capture) had limited or no influence on the survival of neonatal mule deer, desert bighorn sheep, and Rocky Mountain bighorn sheep within the first few days of life. Furthermore, we found that handled mule deer and Rocky Mountain bighorn neonates were recruited at a ...

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

Foetal Cardiac Function in Early Labour and Intrapartum Outcomes: A Prospective Observational Study

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To assess foetal myocardial deformation in normo‐oxygenated foetuses in early labour and its relationship with intrapartum outcomes. Design Single centre prospective study. Setting Referral tertiary maternity unit. Population Uncomplicated singleton term pregnancies in early labour.

Genetic differentiation and adaptive evolution of buff‐tailed bumblebees in Asia

open access: yesInsect Science, EarlyView.
This study investigates the genetic differentiation and local adaptation of the buff‐tailed bumblebee (Bombus terrestris) across its European and Asian populations. Using whole‐genome resequencing, we identified distinct genetic differences between populations, with Asian B. terrestris representing a unique genetic resource.

Starving or Stuffing? Plasticity in Wild Boar Body Mass Variations During Summer in a Mediterranean Area

open access: yesIntegrative Zoology, EarlyView.
Assessing drivers of population dynamics helps to mitigate human–wildlife conflicts. In Mediterranean areas, summer aridity reduces resources, potentially affecting ungulates' body condition and reproduction. In a mixed forested‐rural area, wild boar female body mass increased throughout summer in rainy‐mild years and decreased in hot‐dry years.

Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

open access: yesIntegrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.
