For wild ungulates and their predators, livestock grazing is an important anthropogenic disturbance causing population declines and modifying their interactions over time and space. However, it is poorly understood how fine-scale grazing affects the spatiotemporal responses of predators, prey, and their interactions. Two opposing hypotheses describe a dichotomy of possible effects. The human shield hypothesis states that people can protect prey because predators avoid areas with high human-induced mortality risk, whereas in the human competitor hypothesis, humans compete for prey and negatively impact predators through reduced prey availability. We used camera-trapping data from the Gansu Qilianshan National Nature Reserve in Northwest China to measure occupancy, daily activity patterns, and spatiotemporal interactions between snow leopards (Panthera uncia), the dominant predator, and their ungulate prey in areas with contrasting grazing intensities. The results of grazing were consistent with both the human-shield and human-competitor hypotheses, affecting spatiotemporal patterns and interactions of predators and prey. For the primary prey species, blue sheep (Pseudois nayaur), their spatial and temporal patterns were affected by grazing, which led to a reduction in interaction frequencies with snow leopards. For secondary prey, grazing led to reduced interaction frequencies with snow leopards for white-lipped deer (Przewalskium albirostris) and red deer (Cervus yarkandensis), but increased frequencies for alpine musk deer (Moschus chrysogaster). Our results indicate how both competition among livestock and prey and predator or prey avoidance of grazed areas can impact populations and predator-prey interactions. Our findings are relevant to grazing management and snow leopard conservation.</p>","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142835621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we generated a reference chromosomal-level genome assembly of C. guichenoti on the basis of PacBio HiFi sequencing and Hi-C scaffolding technologies. The final genome assembly was 1.10 Gb in length (contig N50: 28.64 Mb; scaffold N50: 42.39 Mb) with 25 chromosomes. The completeness score of the C. guichenoti genome was 96.4%, and high synteny was detected compared with Danio rerio and Ictalurus punctatus genomes. A total of 24 325 PCGs were annotated for the C. guichenoti genome. Comparative genomics analysis identified 986 expanded gene families in C. guichenoti, which were significantly enriched in GO items associated with the development and interaction of sperm and egg as well as immunity. Furthermore, positively selected genes (PSGs) detected in C. guichenoti were mainly associated with DNA repair, ATP binding, mitochondrion, and lipid homeostasis. Based on the reference genome and resequencing data, the polymorphic microsatellite (SSR) loci were comprehensively analyzed for C. guichenoti, and the top 15 tetra-nucleotide SSR loci were selected for the construction of the genetic maker system after validation through PCR and genotyping. All of these 15 tetra-nucleotide SSR loci without Hardy-Weinberg equilibrium (HWE) deviation showed high polymorphism, good amplification stability, and selective neutrality. The PID (sibs) curves revealed that the subset of four tetra-nucleotide SSR loci (cgui1, cgui5, cgui3, cgui13) was sufficient for accurate identification of C. guichenoti individuals (PIDsib < 0.01). These 15 tetra-nucleotide SSR loci could also serve as genetic markers in subsequent parentage identification and genetic diversity analysis.

The 𝝀 and damping ratio increased with the removal pressure, as expected; the inverse occurred with the generation time. The survivorship of the younger age classes was the most sensitive and elastic vital rate regardless of removal pressure, followed by the breeding onset. The fertility was less relevant on 𝝀.

Nest occurrence was also associated with the cover of agricultural areas (300 m), distances to the nearest agricultural area, the nearest human settlement, and the nearest track. However, the effect of these covariates depended on distance to the nearest paved road, being close to roads located far away from agricultural areas and tracks and near human settlements and tracks. Overall, our results highlighted a trend to nest close to HI when agricultural areas were relatively remote or less represented.

We investigated the influence of salinity stress on the composition of the gut microbiota in T. s. elegans to determine whether it regulates SSC self-renewal and differentiation via the gut-brain-gonad axis. Three salinity groups (0‰, 5‰, and 10‰) were used in this study, and samples were obtained after 6 months of feeding. The mRNA expression of self-renewing genes (GFRα-1, RAS, and ERK) and meiotic initiation genes (RARα, NRG3, and ERBB4) in SSCs decreased with increasing salinity, indicating that salinity affects renewal and differentiation. In addition, harmful bacteria such as Enterococcus and Clostridium were increased in the S10 group, and lower levels of g_norank_f_Eubacteriaceae were negatively associated with γ-aminobutyric acid (GABA), whereas higher Turicibacter levels were positively associated with GABA levels, resulting in increased GABA content in the S5 group. The results show that salinity affects the secretion of neurotransmitters in the brain and negatively regulates the synthesis of reproductive hormones by changing the composition of intestinal microorganisms and metabolites, which affect SSC function.

Following this colonization, significant adaptive evolution occurred in both coding and non-coding regions of the ancestral lineage. This evolution led to notable phenotypic alterations, as evidenced by the reduced body size. Also, due to purifying selection, most ancestral adaptive features persisted in descendant species, indicating a strong element of evolutionary conservatism. However, descendant species evolved novel adaptations to exacerbated environmental challenges in the Tibet Plateau, mainly related to hypoxia response. Furthermore, our analysis underscores the critical role of regulatory variations in descendant adaptive evolution.

Here, we use two decades of morphological data on three rodent species distributed across vast latitudinal gradients in China to estimate temporal and spatial trends of tail, hind-foot, and ear lengths. Further, we test 14 climate variables to identify the critical drivers of these trends and use structural equation modeling (SEM) to analyze whether the effects of climate variables on the appendage lengths are direct or indirect, via effects on body length. Relative to body length, and in contradiction to Allen's rule, all appendage lengths remained unchanged over time and across space. By contrast, absolute appendage lengths increased in one species (Apodemus agrarius) over time and in two species (A. agrarius and Rattus norvegicus) across space; and most of the appendage lengths in the two species were associated with annual mean minimum temperature in the year preceding capture (PreAnnMinTemp). The SEM results suggest that PreAnnMinTemp affected absolute appendage lengths indirectly through body length. In addition, except for tail length in two species and both hind-foot and ear length in one species, absolute appendage lengths scaled allometrically with body length. These results suggest that the distinct temperature-appendage-length patterns among and within species arise from species-specific temperature sensitivities and appendage-specific ontogenetic rates and functions.</p>","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
