The Seocheon Tidal Flat, located in the East Asian-Australasian Flyway, is a critical habitat for waterbirds in Korea. Previous studies, however, have been limited in geographic scope, preventing a comprehensive understanding of spatiotemporal variations and distribution patterns of waterbirds. This study aimed to analyze spatiotemporal variation and distribution patterns of endangered waterbird species to provide a foundation for effective conservation strategies. The Seocheon Tidal Flat was divided into a 1 × 1 km grid, and field surveys were conducted twice monthly from January to December 2023. To investigate the spatiotemporal variations and distribution patterns of endangered waterbird species in the Seocheon Tidal Flat, species with at least 15 recorded coordinate points and not restricted to specific areas were selected for analysis. Seven species were included in the analysis: the Black-faced Spoonbill (Platalea minor), Chinese Egret (Egretta eulophotes), Saunders’s Gull (Saundersilarus saundersi), Eurasian Oystercatcher (Haematopus ostralegus), Bar-tailed Godwit (Limosa lapponica), Great Knot (Calidris tenuirostris), and Far Eastern Curlew (Numenius madagascariensis). The results revealed distinct spatial and temporal distribution patterns, which were influenced by each species’ ecological characteristics. These findings highlight the need for targeted conservation strategies that reflect species-specific distribution patterns and seasonal habitat use.

位于东亚-澳大拉西亚迁徙路线上的舒天潮滩是韩国水鸟的重要栖息地。然而，以往的研究仅限于地理范围，无法全面了解水鸟的时空变化和分布格局。本研究旨在分析濒危水鸟物种的时空变化和分布格局，为制定有效的保护策略提供依据。将西川滩涂划分为1 × 1 km的网格，从2023年1 ~ 12月每月进行2次野外调查。为了研究西川潮滩濒危水鸟物种的时空变化和分布格局，选取了至少有15个记录坐标点且不局限于特定区域的物种进行分析。其中包括黑面琵鹭（Platalea minor）、中华白鹭（Egretta eulophotes）、沙乌斯鸥（Saundersilarus saundersi）、欧亚捕虾鸥（Haematopus ostralegus）、斑尾鹬（Limosa lapponica）、大结鹬（Calidris tenuirostris）和远东杓鹬（Numenius ensis） 7种。结果显示出明显的时空分布格局，受各物种生态特征的影响。这些发现强调需要有针对性的保护策略，以反映物种特定的分布模式和季节性栖息地的利用。

Flueggea suffruticosa (Pall.) Baill. (Phyllanthaceae) is a medicinally significant shrub in traditional medicine, yet its genomic resources remain scarce. In this study, we reported the first complete chloroplast genome of F. suffruticosa, assembled de novo from Illumina NovaSeq 6000 paired-end sequencing data. The 157,521 bp genome exhibited a typical quadripartite structure, consisting of two inverted repeats (26,082 bp each), a large single-copy region (86,561 bp), and a small single-copy region (18,796 bp). It encoded 112 unique genes, including 78 protein-coding, 30 tRNA, and 4 rRNA genes. Codon usage was biased toward A/T, with leucine being the most abundant and cysteine the least frequent amino acid. Phylogenomic analysis of 78 shared protein-coding genes from 28 Phyllanthaceae species resolved several well-supported tribal clades. Flueggea suffruticosa formed a robust subclade with two accessions of Flueggea virosa (Roxb. ex Willd.) Royle within Phyllantheae. Notably, Phyllanthus L. was found to be polyphyletic due to the nested positions of Breynia J.R.Forst. & G.Forst. and Glochidion J.R.Forst. & G.Forst., reaffirming the long-standing taxonomic complexities within the tribe. The complete chloroplast genome of F. suffruticosa offers a valuable genomic resource for future evolutionary, phylogenetic, and conservation studies within Flueggea and the broader Phyllanthaceae family.

The Mongolian Gull (Larus mongolicus) is a widely distributed species, yet it remains one of the least understood in terms of its migration behavior. This study investigates the migration patterns and habitat usage of the Mongolian Gull. Using satellite tracking data, we collected information on 20 complete migrations from 7 individuals between 2020 and 2023. The tracked gulls migrated an average distance of 2405.5 km [standard deviation (SD) ± 327.9] in autumn and 2219.9 km (SD ± 666.5) in spring, traveling between their breeding grounds in northern Mongolia and their wintering sites in the Yellow Sea region. These wintering locations include the coastal areas of Shanghai, Yantai, Laizhou Bay, Bohai Bay, Liaodong Bay, and the coastal region of Donggang in China. In South Korea, they have been observed in Goyang, as well as along the coastal region of Gukhwado Island and in Gunsan. This study reveals the variability in migration routes among the sub-population of Mongolian Gulls in northern Mongolia, highlighting different stopovers and distinct migratory patterns. Based on this new understanding of the biogeographical subpopulation structure of the Mongolian Gull, it is crucial to integrate data on population size, distribution throughout their annual life cycle, and conservation status across their range.

蒙古鸥（Larus mongolicus）是一个分布广泛的物种，但就其迁徙行为而言，它仍然是最不为人所知的物种之一。研究了蒙古鸥的迁徙模式和栖息地利用。利用卫星跟踪数据，我们收集了2020年至2023年间来自7个个体的20次完整迁移的信息。秋季平均迁徙距离为2405.5 km（标准差±327.9），春季平均迁徙距离为2219.9 km（标准差±666.5），往返于蒙古北部繁殖地和黄海地区越冬地之间。这些越冬地点包括上海沿海、烟台、莱州湾、渤海湾、辽东湾和中国东港沿海地区。在韩国，高阳市以及国花岛沿海地区和群山都观察到了它们。本研究揭示了蒙古北部蒙古海鸥亚群迁徙路线的差异性，突出了不同的中途停留点和不同的迁徙模式。基于对蒙古海鸥生物地理亚种群结构的新认识，整合蒙古海鸥种群规模、全年生命周期分布和分布范围内的保护状况数据至关重要。

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。

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。

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。

Two new species of Russula, namely R. atrovinaceopurpurea and R. rufoalbida, were described based on morphological and phylogenetic evidence. Phylogenetic analysis based on internal transcribed spacer (ITS) and concatenated 5-locus (nrLSU-mtSSU-rpb1-rpb2-tef1-α) datasets confirmed that these two new species were placed within the crown clade of subgen. Russula. Detailed morphological descriptions, phylogenetic analyses of the new species, and comparisons with allied taxa are presented.
