Historical deforestation of lowland tropical forests in the Upper Brahmaputra Valley of the Indian state of Assam has led to habitat fragmentation, negatively impacting the ecology of these natural ecosystems. Local populations of arboreal species, such as Capped Langurs (Trachypithecus pileatus), have become confined to isolated fragments and are at risk of disappearing entirely due to ongoing anthropogenic activities. This study aimed to assess changes in the occupancy of Capped Langurs across 40 rainforest fragments between February 2019 and January 2020 and to identify the ecological and landscape-level factors influencing their persistence. Using generalized linear models, we examine the attributes at both patch and landscape levels that influence the occurrence of Capped Langurs in these fragments. Of the 40 surveyed sites, we found Capped Langurs only in 11 fragments. We discovered that the diversity of food tree species in these fragments had the most significant impact, explaining the presence of Capped Langur troops. Our findings highlight the urgency of targeted habitat restoration, emphasizing the need to enhance and protect food and roost tree diversity in these degraded fragments. This will ensure a rich composition of native food and roosting trees to support Capped Langurs in these rainforest fragments.

印度阿萨姆邦上布拉马普特拉河谷低地热带森林的历史砍伐导致栖息地破碎化，对这些自然生态系统的生态产生了负面影响。当地的树木物种种群，如帽叶猴（Trachypithecus pileatus），已经局限于孤立的片段，并且由于持续的人类活动而面临完全消失的危险。本研究旨在评估2019年2月至2020年1月期间40个热带雨林片段中帽叶猴的占用变化，并确定影响其持久性的生态和景观水平因素。利用广义线性模型，我们研究了斑块和景观水平上影响叶猴在这些碎片中发生的属性。在40个被调查的地点中，我们只在11个碎片中发现了冠叶猴。我们发现，在这些碎片中，食物树种的多样性产生了最重要的影响，这解释了帽叶猴部队的存在。我们的研究结果强调了有针对性的栖息地恢复的紧迫性，强调了加强和保护这些退化碎片中食物和栖息树木多样性的必要性。这将确保当地食物和栖息树木的丰富组成，以支持这些雨林碎片中的帽叶猴。

The red panda is known for its patchy distribution and low population density. The studies on red panda are conducted throughout Nepal in both protected areas and outside protected areas; however, systematic studies focusing on their distribution and habitat use remain limited. This study has attempted to provide site-specific data on red panda presence and habitat characteristics in Dhorpatan Hunting Reserve. The study was conducted from October 22 to November 7, 2022, and March 22 to March 28, 2023, with the aim to determine the distribution and habitat association of red panda in the area. The study utilized presence and absence points of red panda to model habitat characteristics. Random forest was used to assess the importance of each environmental variable, and a generalized linear model was used to identify the specific variables associated with red panda habitat selection. Indirect signs of red panda were observed at elevations ranging from 3097 m to 3549 m with a sign abundance rate of 0.68 signs/km. The findings showed that abundance of twisted-branched trees, bamboo coverage, aspect, and naturally fallen logs showed a positive association with presence of red panda, while proximity to water sources and canopy cover showed a negative association.

小熊猫以其零星分布和低种群密度而闻名。对小熊猫的研究在尼泊尔各地的保护区和保护区外进行；然而，对其分布和生境利用的系统研究仍然有限。本研究试图提供在多帕坦狩猎保护区小熊猫的存在和栖息地特征的特定地点的数据。研究于2022年10月22日至11月7日和2023年3月22日至3月28日进行，目的是确定该地区小熊猫的分布和栖息地关系。利用小熊猫的存在点和缺失点来模拟生境特征。采用随机森林法评估各环境变量的重要性，采用广义线性模型识别影响小熊猫生境选择的具体变量。在海拔3097 ~ 3549 m范围内观察到小熊猫的间接标志，标志丰度为0.68个/km。结果表明，曲枝树的丰度、竹盖度、坡向和自然落木与小熊猫的存在呈正相关，而与水源的接近程度和冠层盖度呈负相关。

Ceratophyllum is the only genus in the order Ceratophyllales and the family Ceratophyllaceae; however, the taxonomic classification of Ceratophyllum has long been debated. Previous studies have primarily relied on morphological characteristics and a few genetic markers for molecular analyses. However, inconsistencies between morphological characteristics and molecular data have often been observed, and previous studies have been insufficient in accurately establishing the phylogenetic placement of Ceratophyllum. Therefore, this study sequenced and assembled two Ceratophyllum (156,104–156,252 bp) by Illumina Truseq Nano sequencing. The overall chloroplast genome structure, GC content (38.2%), and gene content (113 genes) showed high conservation. This study identified four useful markers (trnK-rps16, trnL-ndhJ, ndhF-rpl32, and rpl32-trnL) that have not been previously examined in molecular research, which could be used as molecular markers. Phylogenetic analyses showed that Ceratophyllales is the sister group to eudicots. The genus Ceratophyllum taxa are a monophyletic group, and C. demersum is sister to C. demersum var. quadrispinum and C. demersum var. inerme. All chloroplast genes in Ceratophyllum exhibited nonsynonymous/ synonymous ratio well below one, indicating that they are evolving under purifying selection. This study provides chloroplast genome data for the Ceratophyllum genus, offering valuable molecular resources to support future taxonomic classification and phylogenetic studies.

角藻是角藻目和角藻科唯一的属；然而，角藻门的分类一直存在争议。以前的研究主要依赖于形态学特征和一些遗传标记进行分子分析。然而，形态学特征和分子数据之间的不一致性经常被观察到，并且以前的研究在准确确定角藻门的系统发育位置方面还不够。因此，本研究利用Illumina Truseq纳米测序技术对两株角藻（Ceratophyllum, 156,104-156,252 bp）进行测序和组装。叶绿体基因组总体结构、GC含量（38.2%）和基因含量（113个基因）具有较高的保守性。本研究发现了trnK-rps16、trnL-ndhJ、ndhF-rpl32和rpl32-trnL这四个在分子研究中未被检测到的有用标记物，它们可以作为分子标记物使用。系统发育分析表明，角鼻藓属是菊科的姐妹类群。角鼻草属是一个单系类群，角鼻草是角鼻草和角鼻草的姊妹种。所有角藻叶绿体基因的非同义/同义比值均低于1，表明它们是在净化选择下进化的。本研究提供了角藻属植物叶绿体基因组数据，为今后的分类分类和系统发育研究提供了宝贵的分子资源。

Aphis glycines Matsumura, 1917 is a significant agricultural pest worldwide, responsible for the damages to soybeans. In this study, we have assembled three mitogenomes of A. glycines based on the public next-generation sequencing raw reads generated for the whole genome project. Phylogenetic analysis revealed that one of the A. glycines mitogenomes (partial genome; KT889380) was misidentified. Intraspecific variations identified from four aphid species, Aphis glycine, Aphis gossypii, Aphis craccivora, and Myzus pericae mitogenomes exhibited that A. glycines mitogenomes contained a small number of single nucleotide polymorphisms (SNPs) but a large coverage of insertions and deletions (INDELs). In addition, nad2 and nad3 of the A. glycines mitogenomes presented the largest number of SNPs among genes. Various structural variations of transfer RNAs in the three species were investigated. Nucleotide diversity analysis of each gene displayed the same trend between Aphis and Aphididae mitogenomes. Identification and comparison of simple sequence repeats (SSRs) from A. glycines mitogenomes showed that meaningful variations of SSRs were found in the repeat region between nad3 and nad5. Consequently, the observed intraspecific variation within Aphididae species, including A. glycine, can be leveraged to develop molecular markers that facilitate the distinction of populations within species.

松村蚜虫（Aphis glycine Matsumura, 1917）是一种世界性的重要农业害虫，对大豆造成危害。在本研究中，我们基于全基因组计划生成的公开下一代测序原始reads组装了A.甘氨酸的三个有丝分裂基因组。系统发育分析表明，甘氨酸A. glycines有丝分裂基因组（部分基因组；KT889380）鉴定有误。从甘氨酸蚜虫、棉蚜、裂唇蚜虫和皮蚜四种蚜虫的有丝分裂基因组中鉴定出的种内变异表明，甘氨酸蚜虫有丝分裂基因组包含少量的单核苷酸多态性（snp），但包含大量的插入和缺失（INDELs）。此外，A.甘氨酸有丝分裂基因组nad2和nad3的snp在基因中最多。研究了三种植物中转移rna的不同结构变化。各基因的核苷酸多样性分析在蚜虫和蚜虫科有丝分裂基因组中显示出相同的趋势。对甘氨酸有丝分裂基因组的简单重复序列（SSRs）进行鉴定和比较，发现nad3和nad5之间的重复序列存在显著差异。因此，可以利用观察到的包括甘氨酸蚜属在内的蚜虫科物种的种内变异来开发分子标记，以促进物种内种群的区分。

In this study, we investigated the phylogeography of the Rattus rattus Complex (=RrC) in Peninsular Thailand. A total of 945 base pairs of cytochrome b gene for 340 specimens were analyzed, including 46 specimens newly collected in this study. Phylogenetic inference using maximum likelihood and Bayesian Inference (BI) based on a partitioned substitution model showed that R. rattus Complex is grouped into six major lineages, with haplotypes from Thailand belonging to RrC Lineage II, RrC Lineage IV, and RrC Lineage VI. The haplotype diversity (h) and nucleotide diversity (π) were 0.958 and 0.03319 for the three lineages. The genetic distances were 0.78, 0.98, and 1.26 within RrC Lineage II, RrC Lineage IV, and RrC Lineage VI, respectively, and 5.93 between RrC Lineage II and RrC Lineage IV, 5.54 between RrC Lineage II and RrC Lineage VI, and 4.91 between RrC Lineage IV and RrC Lineage VI. This study elucidated that Peninsular Thailand and adjacent islands in the Andaman Sea involve such three lineages. The overlapped distribution of multiple lineages in Peninsular Thailand and Andaman Sea islands may result from population exchange and dispersal with the northern Indochina in RrC Lineage II and RrC Lineage IV, and with southern Sunda RrC Lineage VI.

本研究对泰国半岛Rattus Rattus Complex （=RrC）进行了系统地理学研究。共分析340份标本细胞色素b基因945个碱基对，其中新采集标本46份。基于划分替代模型的最大似然和贝叶斯推理（BI）结果表明，泰国褐家鼠复合体可划分为6个主要谱系，单倍型分别属于RrC谱系II、RrC谱系IV和RrC谱系VI， 3个谱系的单倍型多样性(h)和核苷酸多样性（π）分别为0.958和0.03319。RrC世系II、RrC世系IV和RrC世系VI的遗传距离分别为0.78、0.98和1.26，RrC世系II与RrC世系IV之间的遗传距离为5.93，RrC世系II与RrC世系VI之间的遗传距离为5.54，RrC世系IV与RrC世系VI之间的遗传距离为4.91。泰国半岛和安达曼海诸岛多世系的重叠分布可能是与印度支那北部的RrC世系II和RrC世系IV以及巽他南部的RrC世系VI种群交换和分散的结果。

The study explored diversity and activity patterns in the Lapchi Valley, Gaurishankar Conservation Area, Central Himalaya, Nepal, through a camera trap survey conducted from 2018 to 2023. Four pheasant species were recorded: the blood pheasant (Ithaginis cruentus), Himalayan monal (Lophophorus impejanus), kalij pheasant (Lophura leucomelanos), and crimson horned pheasant (Tragopan satyra). A total of 26 camera traps were installed at elevations ranging from 2200–4700 meters above sea level. The blood pheasant was the most frequently recorded species, with 94 events, while the crimson horned pheasant was observed only once. Activity patterns revealed that all species were diurnal, with distinct activity peaks for each. The study also found moderate temporal overlap (Δ = 0.52) between the Himalayan monal and blood pheasant, indicating coexistence with minimal competition. This research provides crucial baseline data on pheasant diversity in the Gaurishankar Conservation Area, emphasizing the region's importance for conservation.

该研究通过2018年至2023年进行的相机陷阱调查，探索了尼泊尔喜马拉雅中部高里尚卡尔保护区拉普奇山谷的多样性和活动模式。记录到血雉（Ithaginis cruentus）、喜马拉雅野鸡（Lophophorus impejanus）、卡利野鸡（Lophura leucomelanos）和红角野鸡（Tragopan satyra） 4种。在海拔2200米至4700米的高度共安装了26个相机陷阱。血雉是记录最频繁的物种，有94次，而深红色角雉只被观察到一次。活动模式显示，所有物种都是昼行性的，每个物种都有不同的活动高峰。该研究还发现喜马拉雅野鸡和血雉之间存在适度的时间重叠（Δ = 0.52），这表明它们在最小竞争的情况下共存。这项研究为Gaurishankar保护区的野鸡多样性提供了重要的基线数据，强调了该地区保护的重要性。

This study defined alpine and subalpine zones in South Korea based on the natural environment, plant distribution patterns, and references to domestic and international literature. Alpine and subalpine plants were classified using five criteria, including their distribution in alpine zones and their global distribution range, focusing on the species listed in the national species list. The alpine zone lies above the tree line and is dominated by tundra vegetation, including shrubs, herbs, and lichens. A gradual reduction in tree height and density with increasing elevation and shrubs, krummholz, dwarf krummholz, and tree islands characterized the subalpine zone. The Korean Peninsula native alpine and subalpine plants were classified into 195 taxa comprising 43 families, 113 genera, 167 species, 3 subspecies, and 25 varieties. Notably, Ericaceae and Asteraceae accounted for the highest proportions, with 20 taxa each. The life forms were divided into 35 woody and 160 herbaceous taxa. In total, 72 taxa of alpine and subalpine plants have been identified in South Korea. Most were isolated from the high-altitude summit areas and ridges of Mt. Halla, Mt. Jiri, and Mt. Seorak. However, alpine plants are likely affected by climatic and environmental changes, potentially leading to a decline in population and species.

本研究根据自然环境、植物分布格局，并参考国内外文献，对韩国的高山和亚高山带进行了界定。根据高寒地区分布和全球分布范围5个标准对高寒和亚高寒植物进行分类，重点对列入国家物种名录的物种进行分类。高山地带位于林木线以上，主要是苔原植被，包括灌木、草本植物和地衣。随着海拔的升高，树木高度和密度逐渐降低，灌木、krummholz、矮krummholz和树岛是亚高山带的特征。将朝鲜半岛原生高山和亚高山植物划分为43科113属167种3亚种25变种195个分类群。其中，Ericaceae和Asteraceae所占比例最高，各有20个类群。生活型分为35个木本类群和160个草本类群。在韩国共鉴定出72个高山和亚高山植物分类群。大部分被隔离在汉拿山、智异山、雪岳山等高海拔地区和山脊上。然而，高山植物可能受到气候和环境变化的影响，可能导致种群和物种的减少。

Acarospora albicans sp. nov. was collected in Balochistan and Gilgit Baltistan. Comparative morphoanatomical research, chemical analysis, and (Internal transcribed spacer) ITS-based DNA analyses all support its placement within the genus Acarospora. Acarospora albicans sp. nov. is closely related to A. pulvinata and characterized by crustose to subsquamulose thallus, brown to dark reddish brown upper surface, strongly concave to slightly convex, 0.8–1.5 mm squamules, 0.6 mm apothecia, hymenium 100–180 μm, hypothecium pale brown, 30–35 μm, ascospores 3–4 × 0.6–1 μm and growing on calcareous rocks.
