The mitochondrial genome of the endemic and endangered trumpet-nosed bat Musonycteris harrisoni (Chiroptera: Phyllostomidae) 地方性和濒危的角鼻蝙蝠的线粒体基因组哈里斯毛滴虫(翼手目:毛滴虫科)

ABSTRACT The trumpet-nosed bat Musonycteris harrisoni (family Phyllostomidae) is endemic to the western Pacific slope of Mexico, and is considered endangered given prolonged and continuous population decline. This study, for the first time, assembled and characterised in detail the mitochondrial genome of this species that is in need of genomic resources. The mitogenome of Musonycteris harrisoni is 16,668 bp in length and encodes 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and a relatively long non-coding putative control region (CR) 1229 bp in length. Mitochondrial synteny is identical to that reported before in the family Phyllostomidae. As reported before in all phyllostomids, most mitochondrial genes are encoded on the heavy strand (H-strand), except for nad6 and eight tRNA genes that are encoded on the light strand (L-strand). All the tRNAs exhibit a ‘cloverleaf’ secondary structure, except tRNA Serine-1 that is missing the dihydrouridine (DHU) arm. All 13 mitochondrial PCGs are evolving under purifying selection, with atp8, nad4l and nad6 experiencing relaxed purifying selection in comparison to the other PCGs. Tandem repeats, microsatellites, and hairpin structures are observed in the CR of Musonycteris harrisoni, in agreement with what has been reported before in other cofamilial bats. The CR contains three functional domains: extended termination associated sequence (ETAS) domain, central domain, and conserved sequence block (CSB) domain. The mitochondrial genome sequence herein characterised completely and in detail represents a new genomic resource for M. harrisoni that will further the understanding of genetic diversity in this endangered species.
摘要:角鼻蝙蝠Musonyteris harrisoni(Phyllotomidae科)是墨西哥西太平洋斜坡的特有物种,由于种群数量持续下降,被认为处于濒危状态。这项研究首次对需要基因组资源的该物种的线粒体基因组进行了详细的组装和表征。哈里斯毛滴虫的有丝分裂基因组长度为16668bp,编码13个蛋白质编码基因(PCG)、22个转移RNA基因(tRNA)、两个核糖体RNA基因(rRNA)和一个长度为1229bp的非编码推定控制区(CR)。线粒体同源性与以前报道的Phyllostomitidae家族的线粒体同源性相同。如前所述,在所有叶口类中,除了nad6和8个tRNA基因编码在轻链(L-链)上外,大多数线粒体基因编码在重链(H-链)上。除了缺少二氢尿苷(DHU)臂的tRNA丝氨酸-1外,所有tRNA都表现出“苜蓿叶”二级结构。所有13种线粒体PCG都在纯化选择下进化,与其他PCG相比,atp8、nad4l和nad6经历了放松的纯化选择。在哈氏Musonyteris harrisoni的CR中观察到串联重复序列、微卫星和发夹结构,这与之前在其他同科蝙蝠中报道的一致。CR包含三个功能结构域:扩展终止相关序列(ETAS)结构域、中心结构域和保守序列块(CSB)结构域。本文完整而详细地描述了线粒体基因组序列,它代表了M.harrisoni的一种新的基因组资源,将进一步了解这种濒危物种的遗传多样性。

ABSTRACT The volcano rabbit Romerolagus diazi is an endemic neotropical species restricted to the central part of the Trans-Mexican Volcanic Belt and considered ‘endangered’ by the International Union for Conservation of Nature Red List of Threatened Species. This study formally tested whether complete mitochondrial genomes of R. diazi can be assembled from non-enriched metagenomic libraries generated from eDNA (field droppings) using Illumina 300 bp pair-end reads. Using a direct assembly strategy, the mitogenome of R. diazi was assembled and circularised using the pipeline GetOrganelle with a coverage of 18.5× from one eDNA sample. A second strategy in which reads were first mapped to a reference mitochondrial genome and then assembled using the software SPAdes retrieved a second nearly complete mitogenome (2.7×) of R. diazi from a second eDNA sample. Complete or nearly complete mitochondrial genomes were not retrieved from two other eDNA samples. The organisation of the complete or nearly complete mitochondrial genomes recovered from eDNA samples is identical to that already described for the studied species. A phylomitogenomic analysis based on all protein coding genes (PCGs) demonstrated that the mitochondrial genomes assembled from eDNA can and do reliably identify the sequenced samples as belonging to R. diazi and distinguished the same samples from closely and distantly related cofamilial species. This study demonstrates the feasibility of retrieving fully accurate whole and nearly complete mitochondrial chromosomes of host species from eDNA without enrichment strategies and using straightforward bioinformatics pipelines. This new genomic resource developed for R. diazi represents a new tool to boost conservation strategies (bioprospecting and/or biomonitoring) and improve our understanding of the evolutionary history of this endemic and endangered species.

Natural history and ecology of the slender crayfish (Faxonius compressus): an ecosystem engineer in the Western Highland Rim, USA 细长小龙虾(Faxonius compressus)的自然历史和生态学:美国西部高地边缘的生态系统工程师

ABSTRACT Ecosystem engineers influence the physical environment, which changes the distribution and availability of resources to other organisms. Based on their burrowing abilities, freshwater crayfish have been widely recognised as ecosystem engineers. Crayfishes construct burrows that range from simple, rudimentary depressions in aquatic systems, to complex, labyrinth-like terrestrial burrows that may be significant distances from permanent water bodies. Here, we investigate ecosystem engineering and burrowing of the slender crayfish, Faxonius compressus, which lives in lotic environments characterised by an abundance of small cobble- and gravel-sized substrates. Without larger substrates to burrow under, we found F. compressus populations construct extremely high densities of burrows across riffle, run and pool macrohabitats. Based on the average number of burrows, a 5 × 100 m pool is estimated to contain an average of 25,860 burrows. We also conducted behavioural observations of this species to glean information on their natural history. Faxonius compressus regularly inhabits and competes for ownership of burrows which serve as a shelter from predators. Importantly, these burrows are not only used by F. compressus; we documented other crayfishes and fish species utilising these burrows. In total, we documented two other crayfishes and six fish species utilising F. compressus burrows. We discuss the ecosystem engineering abilities of this species in relation to other crayfish and suggest future avenues of research to elucidate this species’ natural and life history.

Based on their burrowing abilities, freshwater crayfish have been widely recognised as ecosystem engineers. Crayfishes construct burrows that range from simple, rudimentary depressions in aquatic systems, to complex, labyrinth-like terrestrial burrows that may be significant distances from permanent water bodies. Here, we investigate ecosystem engineering and burrowing of the slender crayfish, Faxonius compressus, which lives in lotic environments characterised by an abundance of small cobble- and gravel-sized substrates. Without larger substrates to burrow under, we found F. compressus populations construct extremely high densities of burrows across riffle, run and pool macrohabitats. Based on the average number of burrows, a 5 × 100 m pool is estimated to contain an average of 25,860 burrows. We also conducted behavioural observations of this species to glean information on their natural history. Faxonius compressus regularly inhabits and competes for ownership of burrows which serve as a shelter from predators. Importantly, these burrows are not only used by F. compressus; we documented other crayfishes and fish species utilising these burrows. In total, we documented two other crayfishes and six fish species utilising F. compressus burrows. We discuss the ecosystem engineering abilities of this species in relation to other crayfish and suggest future avenues of research to elucidate this species’ natural and life history.","PeriodicalId":16568,"journal":{"name":"Journal of Natural History","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135860289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT The present study describes and illustrates two new species of the subgenus Petrobia (Petrobia), P. (P.) arabica sp. nov. and P. (P.) tabarjalensis sp. nov., collected in the Northern Region (Jouf) of Saudi Arabia They were found inhabiting wild host plants, Haloxylon salicornicum (Amaranthaceae) and Chrozophora sp. (Euphorbiaceae), respectively. http://www.zoobank.org/urn:lsid:zoobank.org:pub:BB89B241-950D-446F-9207-E25A39345E1B
