Wild edible plants contribute significantly to food security, environmental protection, cultural heritage preservation, economic diversification, and the development of communities. In this paper, we present an inaugural ethnobotanical investigation of the traditional knowledge on wild edible plant species from Makkah, Kingdom of Saudi Arabia. Ethnobotanical fieldwork was conducted in Makkah from January to February 2025. Ethnobotanical data pertaining to wild edible plants were collected from 102 informants through free listing, semi-structured interviews, field observations, and a survey of the market. The data were analyzed based on descriptive statistics, the relative frequency of citation, preference ranking, and priority ranking. Forty-one out of one hundred and eighty-four wild plants were gathered and recognized as wild edible plant species belonging to twenty-one families. Poaceae showed the greatest species diversity, comprising five plant species (12%). Phoenix dactylifera L. is the most common wild edible plant. Notably, 11 of the 41 wild edible plants identified in this study had never been reported in the Kingdom of Saudi Arabia before. Wild edible plants are currently threatened by several anthropogenic sources in the research region, including overgrazing, fuel wood collection, and the repeated use of multiple species. Therefore, to ensure sustainable future usage, wild food plants must be used carefully and should be the subject of targeted conservation efforts from all stakeholders.

Tribals are known as the torchbearers of ethnobotany. Traditional plant-derived utility products (PUPs) are environmentally friendly, cost-effective, and easy to handle, and are extensively used by the forest-dwelling Gaddi and Sippi tribes of the Union Territory (UT) of Jammu and Kashmir for their subsistence. The present study is an attempt to document the invaluable traditional knowledge on wild plants and PUPs possessed by the Gaddi and Sippi tribes before it perishes completely, as this knowledge is transmitted orally to the next generation. Semi-structured schedules were used for the collection of data regarding the method of making and usage of PUPs and the plant species used for making such products. The cultural importance index (CI) and factor informant consensus (Fic) were calculated to find the predominant plant species and the consensus among informants for species used in making PUPs, respectively. A total of 52 plant species from 28 families and 46 genera are used in the study area for making 93 PUPs. Tools, with a 55.9% contribution, were the major PUP category. Cedrus deodara, used for making 36 PUPs and having a 4.9 CI value, was the most utilized and important tree species for the Gaddi and Sippi tribes. The values of Fic ranged between 0.97 (miscellaneous PUPs) and 0.99 (containers/storage PUPs). The present study documented 43 plant species as new ethnobotanical records from the UT of Jammu and Kashmir for their use in traditional plant products. The Gaddi and Sippi tribes in the study area have extensive knowledge about forest-based PUPs and the associated plant species. This invaluable knowledge can be exploited for developing new resources for some value-added traditional plant products and agro-based cottage industries, which could play an important role in socio-economic upliftment and livelihood promotion of tribals.

Within a dam reservoir landscape in the Western Black Sea Region of Türkiye, a dense young-mature stand composed diversely of oriental beeches, European hornbeams, sessile oaks, and silver lindens was chosen as a study field to analyze canopy parameters and to determine phenological patterns along the altitudinal gradients. Referring to the air-soil temperature and precipitation data, intra-annual eco-physiological characteristics of that stand tree canopies, were aimed to be determined regarding those altitudinal gradients. For each of the 10 altitudinal gradients, the mixed deciduous stand canopy physiological characteristics were analyzed by hemispherical photographing. Canopy parameters were acquired from those digital hemispherical photographs, which were confirmed with secondary LAI data from the LAI-2200C. Leaf Area Index, Light Transmission, Canopy Openness, and Gap Fraction were obtained during a total of 21 study field visits throughout the monitoring year. Beginning from a theoretical leafless stage with 0.51 m2 m−2, average LAI increased to 0.89 m2 m−2 during budburst stage, and then gradually up to 3.60 m2 m−2 during climax leaf period, and then to 1.38 m2 m−2 during senescence period, and gradually down to 0.50 m2 m−2 during the next theoretical leafless stage. However, average LT (64%, 61%, 9%, 36%, 74%), CO (65%, 62%, 9%, 37%, 75%), and GF (18%, 14%, 1%, 8%, 14%) followed opposite patterns. Though no apparent trend was valid for those canopy parameters from the lowest to the highest altitudinal gradient, their obvious intra-annual patterns emerged as compatible with the annual air-soil temperature data course.

Compared with traditional field techniques, automated and noninvasive bird monitoring techniques, such as passive acoustic monitoring, offer significant advantages. However, the extensive data collected through passive acoustic monitoring can be challenging to analyze and may require the use of machine learning algorithms for efficient processing. BirdNET is a user-friendly and ready-to-use machine learning tool that can recognize more than 6500 wildlife species, including several tropical species. However, the performance of BirdNET in tropical ecosystems has rarely been assessed. Here, we evaluate the effectiveness of BirdNET for monitoring the vocal activity of three Neotropical wetland species from recordings collected over a year in the Brazilian Pantanal: Green Ibis (Mesembrinibis cayennensis), Limpkin (Aramus guarauna), and Sunbittern (Eurypyga helias). BirdNET was able to detect the presence of the three species in 82–92% of the recordings with known presence. Similarly, BirdNET’s ability to correctly identify vocalizations was consistently greater than 77% (range 77–98%), confirming its effectiveness for monitoring these three tropical bird species. The peak vocal activity for the three species occurred during crepuscular periods, at the end of the rainy season, and during the receding season, a period when the risk of nest damage from flood pulses is low and food availability is high owing to the large presence of small water bodies. The use of machine learning algorithms such as BirdNET may improve bird monitoring in tropical areas but also facilitate research that improves our knowledge of birds’ natural history, which remains unknown for many tropical species.

The wild resources of Spinibarbus caldwelli, once an important economic fish in southern China, have been drastically reduced in recent years due to environmental changes and human activities. The Liuxi River S. caldwelli National Aquatic Germplasm Reserve was established in Conghua District, Guangzhou city, and the release of S. caldwelli was carried out. However, traditional fishery resource survey methods yield less accurate results when the abundance of the surveyed species is low or when they are difficult to catch. As a non-destructive and non-invasive approach, environmental DNA (eDNA) is widely employed in aquatic species monitoring, though its detection efficiency may be affected by environmental conditions. Therefore, this study explored the eDNA monitoring methods of S. caldwelli in Liuxi River from the following four aspects: (1) the relationship between eDNA release and biomass/abundance; (2) the concentration and diffusion range of eDNA over time in a lentic ecosystem; (3) the diffusion range of eDNA in a lotic ecosystem; and (4) the effects of eDNA application in field monitoring. Our results showed a correlation between eDNA concentration and abundance/biomass of S. caldwelli. eDNA of S. caldwelli can diffuse up to 18 m in lentic ecosystems within 2 h and decreases with distance. eDNA of S. caldwelli released by 10 individuals in Liuxi River could be detected 900 m downstream. Field studies in Liuxi River showed that the eDNA method has high sensitivity in detecting the presence or absence of species and is highly consistent with the results of traditional methods. This study explored the application of environmental DNA technology in species monitoring in Liuxi River. Our aim was to evaluate the applicability and potential of eDNA in ecological monitoring of stream fishes.

5-Hydroxytryptamine (5-HT) plays a vital role in the reproductive process of vertebrates and is also present in many invertebrates. The cDNA of the Sepiella japonica 5-HT6 receptor (Sj5-HT6r) was first cloned by RACE (Rapid Amplification of cDNA Ends). The length was 1450 bp, and the predicted open reading frame (ORF) was 1116 bp, which encoded 371 amino acids. Sequence characteristics analysis showed that Sj5-HT6r shares a high degree of identity with 5-HT6r from other cephalopods and forms a sister branch to bivalves. Subcellular localization showed that Sj5-HT6r protein was localized on the HEK293T cell membrane surface. Quantitative Real-time PCR (qPCR) analysis demonstrated that Sj5-HT6r was highly expressed in reproductive organs of both sexes. In particular, transcripts with significant expression were observed at stage III of female gonadal development in tissues of the ovary and nidamental gland, and at stage IV in tissues of the accessory nidamental gland. In situ hybridization (ISH) experiment results indicated that Sj5-HT6r mRNA was primarily distributed in all regions of the optic lobes except the plexiform zone. These results may provide a basis for the future exploration of the reproductive regulation of 5-HT and 5-HT6 receptors in S. japonica.
5-羟色胺（5-HT）在脊椎动物的生殖过程中起着至关重要的作用，也存在于许多无脊椎动物中。采用RACE （Rapid Amplification of cDNA Ends）技术首次克隆了日本血吸虫5-HT6受体（Sj5-HT6r）的cDNA。全长1450 bp，预测开放阅读框（ORF）长度为1116 bp，编码371个氨基酸。序列特征分析表明，Sj5-HT6r与其他头足类动物的5-HT6r具有高度的同源性，是双壳类动物的姐妹分支。亚细胞定位表明，Sj5-HT6r蛋白定位于HEK293T细胞膜表面。实时荧光定量PCR （qPCR）结果显示，Sj5-HT6r在两性生殖器官中均有高表达。特别是在雌性性腺发育的第三阶段，在卵巢和内腺组织中，以及在副内腺组织的第四阶段，有显著表达的转录本。原位杂交（ISH）实验结果表明，Sj5-HT6r mRNA主要分布在视叶丛状区以外的所有区域。这些结果可为进一步探索5-HT和5-HT6受体在粳稻中的生殖调控机制提供基础。

Here I examine the overexploitation of Artemisia granatensis, a narrow endemic medicinal plant species from Sierra Nevada, Spain, and the consequences for its conservation. With over 50,000 flowering plant species used for medicinal purposes worldwide, many species face sustainability issues due to overharvesting and habitat loss. Historical documentation of A. granatensis use dates back to the 13th century, highlighting its significance in traditional medicine. However, this species has suffered extensive overexploitation, particularly in the 19th and 20th centuries, leading to a significant decline in populations. Conservation concerns were first raised in 1909, and despite the species being legally protected since 1982, illegal collection and environmental pressures persist. Today, A. granatensis is critically endangered, with fewer than 2000 individuals remaining in fragmented populations. The study synthesizes the historical and recent literature to understand the long-standing pressures on this species and the limited conservation efforts made. Cultivation of A. granatensis is proposed as a crucial strategy to reduce pressure on wild populations and ensure the survival of this flagship important plant species.

Numerous and diverse groundwater habitats suitable for sustaining aquatic invertebrate communities exist across Australia. These habitats include enclosed subterranean aquifer systems, fractured rock, alluvial aquifers, perched aquifers, artesian springs, and spring-fed seeps and marshes. Crustaceans are a dominant member of these groundwater-associated invertebrate communities, and amphipods, both stygobiont and associated epigean species, are particularly diverse yet are still relatively poorly known. We review both the diversity and distributions of Australian amphipods associated with groundwater habitats, describing hotspots of diversity, providing notes on the unique Australian habitats, and examining the extraordinary species diversity and endemism of the Australian species. Our review highlights the significance of Australian groundwater ecosystems, their associated biodiversity, and the importance in considering these ecosystems in groundwater conservation management plans.

Our review highlights the significance of Australian groundwater ecosystems, their associated biodiversity, and the importance in considering these ecosystems in groundwater conservation management plans.","PeriodicalId":56006,"journal":{"name":"Diversity-Basel","volume":"16 10","pages":"650-650"},"PeriodicalIF":0.0,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/1424-2818/16/10/650/pdf?version=1729600633","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research provides an extensive analysis of the biodiversity and distribution patterns of copepod crustaceans associated with octocoral species. A comprehensive dataset comprising 966 records pertaining to 233 copepod species, encompassing 54 genera, 18 families, and 3 orders, was compiled from 92 scientific papers published between 1858 and 2023, and updated as open data to GBIF. These copepods were found to be closely associated with 183 octocoral species, representing 72 genera and 28 families. The analysis revealed a total of 393 distinct interspecific associations between copepods, classified under the orders Cyclopoida, Harpacticoida, and Siphonostomatoida, and diverse octocorals. Approximately 60% of these associations were reported only once in the literature, which poses challenges to assessing the level of host specificity among the majority of copepod species linked with octocorals. Notably, over 91% of the recorded copepod species were found at depths not exceeding 30 m, with only four copepod species reported at greater depths surpassing 500 m. The presence of these symbiotic copepods was documented across 215 sampling sites situated within 8 of the 12 defined marine ecoregions, with particular attention to the Western Indo-Pacific, Central Indo-Pacific, and Temperate Northern regions. Despite the comprehensive examination of available data, this study highlights substantial gaps in our comprehension of copepod crustacean diversity and distribution in association with octocorals. Moreover, crucial information concerning symbiotic copepods is conspicuously absent for approximately 94% of potential octocoral host species. These disparities emphasize the imperative need for further scientific inquiry to unveil the intricacies of symbiotic relationships and to contribute to a more holistic understanding of copepod–octocoral associations.

This paper presents historical and evolutionary insights into the “tarpan” group of small horses by examining molar tooth enamel ultrastructure. Mathematical methodologies were applied to enhance the analysis. Tooth enamel from species such as Equus gmelini (tarpan), E. latipes, and E. hydruntinus from Pleistocene Ukrainian localities, E. przewalskii from the Chornobyl Exclusion Zone in Ukraine, and E. caballus form sylvaticus (Polish konik) from Roztocze National Park, Poland, underwent scanning microscope examination. Measurements of enamel structures, including prisms (PE) and interprismatic matrix (IPM), were conducted, with the K-index used as their ratio, categorized by enamel type (I, II, III). The findings confirmed that the crystal structures of enamel in these horse groups vary based on genus evolution, diet, and environmental conditions, shaping the enamel’s morphological features. Through analysis, clusters were identified, allowing for potential reconstructions of relationships among study groups. The results revealed distinct differences between species, enabling their classification within an established phenogram. Two primary clusters emerged: one consisting of extinct small horse forms from diverse localities and another grouping modern forms. Notably, the Late Pleistocene European species E. latipes showed close affinities to the latter cluster.
本文通过对马臼齿牙釉质超微结构的研究，提出了马“tarpan”类群的历史和进化认识。运用数学方法加强分析。对来自乌克兰更新世地区的马(tarpan)、E. latipes和E. hydruntinus，乌克兰切尔诺贝利禁区的E. przewalskii和来自波兰Roztocze国家公园的E. caballus形成sylvaticus(波兰konik)的牙釉质进行了扫描显微镜检查。对釉质结构进行了测量，包括棱柱(PE)和柱间基质(IPM)，以k指数作为它们的比率，根据釉质类型(I, II, III)进行了分类。研究结果证实，这些类群的釉质晶体结构根据属进化，饮食和环境条件而变化，形成了釉质的形态特征。通过分析，确定了集群，从而可以重建研究小组之间的关系。结果揭示了物种之间的明显差异，使它们能够在一个既定的物候图中分类。出现了两个主要集群:一个由来自不同地区的灭绝小马组成，另一个由现代马组成。值得注意的是，晚更新世欧洲种E. latipes与后一类群表现出密切的亲缘关系。
