Cymbidium (Orchidaceae: Epidendroideae) includes species of significant horticultural and ecological importance, yet limited research exists on the distribution and phylogeny of Cymbidium hartinahianum, an orchid endemic to North Sumatra, Indonesia. Here, we present the complete plastid genome of Cymbidium hartinahianum. The whole plastid genome was sequenced using the Illumina platform, followed by a pipeline for plastome assembly, annotation, and visualization. The circular genome with a length of 150,370 bp possesses the typical quadripartite structure, consisting of a large single-copy (LSC) region of 84,189 bp, a small single-copy (SSC) region of 14,611 bp, and a pair of inverted repeats (IRs) regions of 25,785 bp. The plastid genome has a total GC content of 37.0%. Annotation revealed 148 gene species, including 96 protein-coding genes, 52 transfer RNA, and four ribosomal RNA (rRNA) genes. Bayesian and maximum likelihood phylogenetic analyses based on 52 plastomes confirmed that C. hartinahianum is sister to C. floribundum and belongs to the Cymbidium section Floribundum. This newly sequenced plastome data will be valuable for future Cymbidium phylogenomic and biogeographical studies. It also provides new molecular data for conservation efforts, including DNA barcoding to help prevent the illegal trade of this endangered orchid.

蕙兰（Cymbidium: Epidendroideae）包括具有重要园艺和生态意义的种，但对印度尼西亚北苏门答腊特有的蕙兰（Cymbidium hartinahianum）的分布和系统发育研究有限。本文报道了春兰（Cymbidium hartinahianum）的完整质体基因组。利用Illumina平台对整个质体基因组进行测序，随后进行质体组装、注释和可视化。全长150,370 bp的圆形基因组具有典型的四分体结构，由84,189 bp的大单拷贝区（LSC）、14,611 bp的小单拷贝区（SSC）和25,785 bp的一对倒置重复区（IRs）组成。质体基因组总GC含量为37.0%。注释共发现148个基因种，其中蛋白质编码基因96个，转移RNA 52个，核糖体RNA （rRNA）基因4个。基于52个质体的贝叶斯和最大似然系统发育分析证实，C. hartinahianum是C. floribundum的姐妹，属于蕙兰科floribundum。这一新测序的质体数据将为今后蕙兰的系统基因组学和生物地理学研究提供有价值的数据。它还为保护工作提供了新的分子数据，包括DNA条形码，以帮助防止这种濒危兰花的非法贸易。

Bird nests form a unique environment that supports a diverse community of invertebrates, which is often overlooked in biodiversity studies. This study analyzed the invertebrate communities in the nests of Calonectris leucomelas on Toshima Island in the Izu Islands, Japan, confirming a total of 292 individuals. Insecta was the dominant class (49%), followed by Arachnida (28.1%), Crustacea (18.8%), Gastropoda (2.1%), Diplopoda (1.7%), and Oligochaeta (0.3%). Within the class Insecta, Coleoptera exhibited the highest abundance (97.2%), with Trox niponensis representing 82.5%. The suborder Metastigmata was identified within Arachnida. In Crustacea, Isopoda (85.5%) and Spherillo dorsalis (80%) were prevalent. Gastropoda included members of Stylommatophora and Architaenioglossa, whereas Diplopoda contained Polydesmida and an unidentified order. Oligochaeta was represented by a single species. Food habit classification revealed 40.4% as “Keratin feeders,” including T. niponensis adults and Trox larvae. “Detritivores” constituted 24%, “Blood-sucking” species in Arachnida accounted for 28.1%, and the “Other” category (1.7%) included various species. Additionally, 5.8% were classified as “Uncertain.” This comprehensive examination provides insights into the intricate relationships between C. leucomelas nests and the diverse invertebrate communities that influence nest utilization patterns and potentially impact nestling survival.

鸟巢形成了一个独特的环境，支持着一个多样化的无脊椎动物群落，这在生物多样性研究中经常被忽视。本研究分析了日本伊豆群岛丰岛Calonectris leucomelas巢穴中的无脊椎动物群落，共确认了292个个体。昆虫为优势纲（49%），其次为蜘蛛纲（28.1%）、甲壳纲（18.8%）、腹足纲（2.1%）、双足纲（1.7%）和寡毛纲（0.3%）。在昆虫纲中，鞘翅目的丰度最高（97.2%），其中niponensis占82.5%。在蛛形纲中鉴定出了散污亚目。甲壳类以等足目（85.5%）和圆球虫（80%）为主。腹足目包括柱头足目和棘足目的成员，而双足目包括Polydesmida目和一个未确定的目。寡毛纲以单一种为代表。40.4%为“角蛋白摄食者”，包括尼泊尼绒螯蟹成虫和Trox幼虫。“食腐动物”类占24%，“吸血”类在蛛形纲中占28.1%，“其他”类占1.7%。此外，5.8%的人被归类为“不确定”。这一全面的研究揭示了白桦冠蚁巢与各种无脊椎动物群落之间的复杂关系，这些关系影响着巢的利用模式，并可能影响雏鸟的生存。

Palaemon paucidens is a freshwater shrimp widely distributed mainly in East Asia. Palaemonid shrimps are collected in Japan for fishing bait. They are also imported from South Korea and China. Currently, there are concerns about the negative impacts that the escape and establishment of these commercially transported individuals may have on local populations, such as on their genetic disturbance. In this study, molecular genetic analysis based on 16S rDNA of 229 individuals collected along the coast of Lake Biwa was conducted to clarify genetic population structure of the shrimp in the lake, which is a major harvesting area in Japan. A total of seven haplotypes (Hap1-7) were identified, and the most frequent haplotype (Hap1) was consistent with the haplogroup (A-I) determined in a previous study. In addition, another haplogroup (A-Biwa) consisting of four haplotypes (Hap2,5-7) was subsequently confirmed, and three (Hap5-7) of these haplotypes were identified for the first time in this study. The other two haplotypes (Hap3, 4) were presumed to be of foreign origin, probably from South Korea. There is strong concern that these foreign haplotypes will not only spread throughout Lake Biwa but will also spread to other parts of Japan via shrimp transport, causing synergistic genetic disturbance.

paucidens Palaemon paucidens是一种淡水对虾，主要分布在东亚。在日本，人们收集巨虾作为鱼饵。它们也从韩国和中国进口。目前，人们担心这些商业运输的个体的逃脱和建立可能对当地种群产生负面影响，例如对其遗传干扰。本研究对日本主要捕捞区琵琶湖（Lake Biwa）沿岸229只虾进行了16S rDNA分子遗传分析，阐明了琵琶湖对虾的遗传群体结构。共鉴定出7个单倍型（Hap1-7），其中最常见的单倍型（Hap1）与前人研究确定的单倍群（A- i）一致。此外，另一个单倍群（A-Biwa）由4个单倍型（Hap2,5-7）组成，其中3个单倍型（Hap5-7）为本研究首次发现。另外两个单倍型（Hap3, 4）被认为是来自国外，可能来自韩国。人们非常担心这些外来单倍型不仅会在琵琶湖传播，还会通过虾类运输传播到日本其他地区，造成协同遗传干扰。

Mountains are rich in endemic species diversity due to various factors, including steep elevational and climatic gradients and high habitat heterogeneity. While the causal factors behind high species endemism have been well worked out with respect to habitat characteristics and climate, the evolutionary mechanisms have received little attention. In this study, we attempt to decipher the evolutionary patterns of diversification of endemic plants in Nepal (Central Himalaya) and Bhutan (Eastern Himalaya) using species-presence records, phylogenetic supertrees, and ancestral area reconstruction methods. We found that the Nepal Himalaya was richer than Bhutan Himalaya with respect to endemic plant species. Maximum diversification of endemic plants in Nepal Himalaya occurred 35-20 million years ago (Mya), and in Bhutan Himalaya, it occurred during 55-45 Mya. Ancestral area reconstructions revealed that the maximum number of endemics in both Nepal and Bhutan Himalaya have diversified from taxa that migrated from Southeast Asiatic Malaysian and Southeast Chinese regions. We conclude that the plant species endemism in the Himalaya is closely linked with the phase-wise gradual uplift of mountains, long-term climate variation, species migration and floristic composition of the neighboring landscapes.

山区特有物种多样性丰富，主要受海拔和气候梯度大、生境异质性强等因素的影响。虽然从生境特征和气候等方面研究了高物种特有性背后的原因，但其进化机制却很少受到关注。在这项研究中，我们试图通过物种存在记录、系统发育超树和祖先区域重建方法来破译尼泊尔（喜马拉雅中部）和不丹（喜马拉雅东部）特有植物的多样化进化模式。我们发现尼泊尔喜马拉雅地区的特有植物种类比不丹喜马拉雅地区丰富。尼泊尔喜马拉雅地区特有植物的最大多样化发生在3500万至2000万年前（Mya），不丹喜马拉雅地区发生在55万至45万年前（Mya）。祖先区重建结果显示，尼泊尔和不丹喜马拉雅地区的特有物种的最大数量已经从东南亚马来西亚和中国东南部地区迁移而来的类群多样化。研究认为，喜马拉雅地区植物物种特有与山地的阶段性逐渐隆起、长期的气候变化、物种迁移和周边景观的植物区系组成密切相关。

Bryophytes (liverworts, mosses, and hornworts) play crucial ecological roles in the ecosystem. However, for the Private Conservation Area (PCA) San Pablo Communal – Gocta Waterfall, there are no records of the diversity of this group of plants, despite being in the territory of the Peruvian Yungas, which is considered to be a biodiversity hotspot. In this study, the diversity of bryophytes within the PCA was characterized using the rbcL. In addition, Shannon-Wiener and Simpson diversity indices were used to evaluate the species richness within the three life zones of the PCA [Tropical Premontane Dry Forest (TP—df), Tropical Low Montane Dry Forest (TLM—df) and Tropical Low Montane Humid Forest (TLM—hf)]. A total of 139 individuals were collected and 83 species were identified; these individuals were located in 49 genera and 33 families. The predominant species were Boulaya sp., Dicranolejeunea axillaris, and Frullania cuencensis. The diversity indices showed a high diversity of bryophytes in the PCA, with values between 2.90 and 3.85 for the Shannon index and 0.93 and 0.97 for the Simpson index. This study provides information based on molecular tools on the bryophyte flora and contributes to the conservation of biodiversity in the San Pablo Communal PCA, Gocta Waterfall.

This study reports the genus Dicladocerus Westwood (Hymenoptera: Eulophidae) from Korea, with a newly reported species, Dicladocerus yoshimotoi Özdikmen. We provide a redescription of this species with photos of diagnostic characteristics based on paratype and Korean specimens. Due to subtle morphological variations among Dicladocerus species, we also provide a key to distinguish species within the Eastern Palaearctic region.

本文报道了一种新报道的韩国双翅蚜属（膜翅目：蜂科），并将其命名为双翅蚜属（Dicladocerus yoshimotoi Özdikmen）。我们提供了一种重新描述与照片的诊断特征，基于准型和韩国标本。由于双角球目物种之间存在细微的形态差异，我们也为东古北地区的物种区分提供了一个关键。

This study investigated the dietary components of an exotic lizard, Diploderma polygonatum polygonatum, at the Yakushima Island World Heritage Site in southern Japan. A total of 430 individuals of various invertebrate species were found in the stomachs of 42 lizards. The most abundant order of prey animals was Hymenoptera (303 individuals in 38 lizards), followed by Coleoptera (36 individuals in 18 lizards) and Lepidoptera (24 individuals in 15 lizards). DNA barcoding was applied to 135 dietary items, and a total of 59 sequences were confirmed. BLAST searches showed that 33 of these 59 sequences presented more than 95% identity to known sequences in the database. These results showed this arboreal lizard captured invertebrates from both ground and arboreal habitats in the introduced area. Although no species on the Japanese Red List were identifiable in the stomachs of the lizards, the database of invertebrate DNA was insufficient to identify the dietary components of this predator at a World Heritage site.

本研究调查了日本南部屋久岛世界遗产地的一种外来蜥蜴——多精蜥的饮食成分。在42只蜥蜴的胃里共发现了430个各种无脊椎动物的个体。被捕食目以膜翅目最多（38只中有303只），其次是鞘翅目（18只中有36只）和鳞翅目（15只中有24只）。利用DNA条形码技术对135个膳食项目进行分析，共确定了59个序列。BLAST检索显示，这59个序列中有33个序列与数据库中已知序列的同源性超过95%。这些结果表明，这种树栖蜥蜴在引进地区的地面和树栖栖息地捕获无脊椎动物。尽管在日本红色名录中没有发现这种蜥蜴的胃中有任何物种，但无脊椎动物DNA数据库不足以确定这种世界遗产地食肉动物的饮食成分。
