During contests over resources, the intensity of fighting and the outcome is often influenced by an interaction between the difference between opponents in the fighting abilities (resource holding potential [RHP]) and the difference in how ...
Morphological diversity of dental and mandibular deformities in Microtus hartingi (Rodentia, Arvicolinae) [0.03%]

We analyzed 104 labial and lingual projections of Harting's vole (Microtus hartingi) mandibles using linear and geometric morphometrics. Incisor and molar overgrowth and mandibular deformations were described in 2 Harting's vole populations...
Trade-offs between proximity and physical contact during group integration in pigs (Sus scrofa domesticus) [0.03%]
猪在群体整合过程中近距离接触和身体接触之间的权衡关系研究

Vocal sound production has been reported in juveniles of mammalian, avian, and nonavian sauropsid lineages. In this last taxon, studies concerning the ontogenetic development of vocalizations have mainly been focused on Crocodylia and Testu...
Disentangling host identity and storage time effects on gut microbiota composition in captive migratory birds using absolute and relative quantification [0.03%]
利用绝对和相对定量方法解析笼养候鸟肠道微生物组成的宿主身份和存储时间效应
Cuiping Liu,Zhiyong Wu,Dongtao Li et al.
Cuiping Liu et al.
Understanding how gut microbiota support migratory birds is essential; yet, fecal sample freshness is often a challenge, particularly for rare species that cannot be captured directly. Here, we collected fecal samples from multiple captive ...
Seasonal dietary shifts in an invasive snail Pomacea canaliculata revealed by 18S rRNA metabarcoding [0.03%]

Elisa Torretta et al.
Animal activity patterns are influenced by endogenous and exogenous factors, with human disturbance and predator presence playing a key role in fearful prey. This study explored diel activity patterns of the roe deer (Capreolus capreolus) a...
Genome-wide copy number variation drives adaptive evolution in Macaca mulatta populations [0.03%]
基因组拷贝数变异驱动了猕猴适应性演化
Yun Liu,Lin Zhang,Xianlin Jin et al.
Yun Liu et al.
Copy number variation (CNV) represents a significant contributor to intraspecific genomic diversity, yet remains under-characterized in rhesus macaque (Macaca mulatta) populations. In this study, we performed whole-genome sequencing of 8 M....
