Cache pilferage, the behavior of rodents seeking or relocating seeds cached by other individuals, is ubiquitous during the scatter‐hoarding process. The effects of canopy openness on cache pilferage have received considerable attention, most of which have focused on the comparison between full canopy cover and completely open areas, such as forest gaps. However, little attention has been given to whether the subtle variation in forest canopy openness affects cache pilferage, although subtle variation in light environments exists in many forests, especially tropical and subtropical forests, where the overall canopy is large and the forest window is relatively small. Here, we directly tested these questions by simulating 400 artificial caches, each containing one seed from four selected tree species, in a subtropical forest in southwestern China. The overall canopy openness of the forest was relatively small (with a mean value of 11.1%), but subtle spatial variation still existed (ranging from 5.7% to 19.5%). Overall, caches with lower canopy openness were more likely to be pilfered and removed faster, although not all species showed the same pattern. Our study highlights that subtle variation in forest canopy openness, even in a closed primary forest, has significant effects on cache pilferage by rodents, which may influence the following seed germination and forest regeneration processes. Additionally, seedling species composition may further be altered because the canopy effects on cache pilferage are species‐specific.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":"148 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140834193","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}

However, knowledge about the association between gut microbiota and host adaptability remains poorly understood. Herein, multi‐omics sequencing approaches were employed to investigate the gut microbiota‐mediated forage adaption in these ruminants. The results revealed that although wild ruminants (WR) of <jats:italic>P</jats:italic>. <jats:italic>hodgsoni</jats:italic> and <jats:italic>P. nayaur</jats:italic> were faced with severe foraging environments with significantly low vegetation coverage and nutrition, the apparent forage digestibility of dry matter, crude protein, and acid detergent fiber was significantly higher than that of <jats:italic>O. aries</jats:italic>. The 16s rRNA sequencing showed that the gut microbiota in WR underwent convergent evolution, and alpha diversity in these two groups was significantly higher than that in <jats:italic>O. aries</jats:italic>. Moreover, indicator species, including Bacteroidetes and Firmicutes, exhibited positive relationships with apparent forage digestibility, and their relative abundances were enriched in the gut of WR. Enterotype analysis further revealed that enterotype 1 belonged to WR, and the abundance of fatty acid synthesis metabolic pathway‐related enzyme genes was significantly higher than enterotype 2, represented by <jats:italic>O. aries</jats:italic>. Besides, the metagenomic analysis identified 14 pathogenic bacterial species, among which 10 potentially pathogenic bacteria were significantly enriched in the gut microbiota of <jats:italic>O. aries</jats:italic>.

In Iran, the widely distributed jird, <jats:italic>Meriones persicus</jats:italic>, serves as the principal reservoir for plague, with a belief in the existence of five out of its six recognized subspecies within the country. However, these subspecies are classified into four mitochondrial cytochrome <jats:italic>b</jats:italic> sub‐lineages (IA, IB, IIA, IIB). This discrepancy, combined with the presence of an unnamed sub‐lineage in central Iran awaiting taxonomic clarification, has left intraspecific taxonomy unsettled and obscured the true alignment between mtDNA sub‐lineages and nominal subspecies. In this study, we investigated the intraspecific variation in the cyt<jats:italic>b</jats:italic> gene across populations sampled throughout Iran, focusing on underexplored regions between the Zagros and Alborz Mountains and central Iran. While our genetic data generally support reported subspecies validity in Iran, we raise questions about <jats:italic>M. p. baptistae</jats:italic>, emphasizing the need for further data from its type territory in Pakistan.

Musk secretion depends on musk gland maturation; however, the mechanism of its development remains elusive. Herein, using single cell multiome ATAC + gene expression coupled with several bioinformatic analyses, a dynamic transcriptional cell atlas of musk gland development was revealed, and key genes and transcription factors affecting its development were determined. Twelve cell types, including two different types of acinar cells (Clusters 0 and 10) were identified. Single-nucleus RNA and single-nucleus ATAC sequencing analyses revealed that seven core target genes associated with musk secretion (<i>Hsd17b2</i>, <i>Acacb</i>, <i>Lss</i>, <i>Vapa</i>, <i>Aldh16a1</i>, <i>Aldh7a1</i>, and <i>Sqle</i>) were regulated by 12 core transcription factors (FOXO1, CUX2, RORA, RUNX1, KLF6, MGA, NFIC, FOXO3, ETV5, NR3C1, HSF4, and MITF) during the development of Cluster 0 acinar cells. Kyoto Encyclopedia of Genes and Genomes enrichment showed significant changes in the pathways associated with musk secretion during acinar cell development. Gene set variation analysis also revealed that certain pathways associated with musk secretion were enriched in 6-year-old acinar cells. A gene co-expression network was constructed during acinar cell development to provide a precise understanding of the connections between transcription factors, genes, and pathways. Finally, intercellular communication analysis showed that intercellular communication is involved in musk gland development.

I assessed the value of scaled cranial shape, based on two‐dimensional landmarks (analyzed using geometric morphometric methods) in distinguishing <jats:italic>Dipodomys</jats:italic> taxa, and in summarizing their variation. My dataset includes 601 adult specimens from 20 species (49 operational taxonomic units ‐ OTUs) across 190 localities. Cranial shape was highly useful in classifying <jats:italic>Dipodomys</jats:italic> taxa without considering geography. The auditory bulla was the most variable region—taxa differed in its hypertrophy, accompanied by different degrees of nearby structure crowding. Cranial shape was weakly allometric, with no significant sexual dimorphism. Weak size dimorphism was detected. (Sub)specific taxonomy is not reflective of shape variation, as the number of subspecies per species is not associated with disparity. Shape had significant phylogenetic signal, but subspecies did not always cluster with conspecifics and species did not always cluster according to phylogenetic relationship/taxonomy. Shape variation was correlated with climate, and species differed in morphological disparity and degree of specialization, which may contribute to divergence in shape variation patterns from phylogeny. <jats:italic>D. deserti</jats:italic> was the most specialized species, diverging greatly from the genus mean; <jats:italic>D. heermanni</jats:italic> was the least specialized.
