To date, 33 species in the genus are known to be distributed in Korea (World Spider Catalog, 2020), placed into three species-groups, viz, P. crypticolens-group (4 spp.), P. phalangioides-group (1 sp.) and P. phungifor mesgroup (28 spp.) (Huber, 2011; Wang et al., 2020). The endemic species diversity of Korean Pholcus species belonging to phungiformes-group was first noticed by Paik (1978), describing six new species. Later many indigenous species in this species-group were discovered by several arachnologists, contributing to the current species diversity of the species-group in Korea. Surprisingly, over the half of the species were found in the last decade (Huber, 2011; Seo, 2014; Kim and Ye, 2015; Kim and Kim, 2016; Seo, 2018).

In recent years, a proper hierarchical classification system for this group was established based on genome analysis. Conse­ quently, on August 2020, the phylum Actinobacteria con­ sisted of 6 classes, 46 orders, 78 families and more than 400 genera [LPSN (https://www.bacterio.net/); Salam et al., 2020]. Members of the phylum Actinobacteria showed great diversity in terms of their habitat, morphology and physi­ o logy (Goodfellow and Williams, 1983). Actinobacterial species are relatively abundant in terrestrial and aquatic environments where they are involved in the decomposi­ tion and recycling of organic matter (Servin et al., 2008). In addition to their saprophytic property, several genera, such as Mycobacterium, Corynebacterium (Dangle et al., 2019) and Clavibacter (Hwang et al., 2019), are patho­ genic to animals (including humans) and plants (Qin et al., 2011). Also, endophytic actinobacteria have been isolated from a variety of healthy plants (Qin et al., 2011).

They play an important role as the primary producers in freshwater and marine environ­ ments, and they contribute significantly to the photosyn­ thesis activity on Earth (Lee et al., 2019). In addition, dia­ toms are used widely across the world for environmental monitoring because different species of diatom typically have specific habitat preferences, and they react quickly to environmental changes (Dixit et al., 1992; Round et al., 2007). For example, species like Cyclotella meneghiniana and Thalassiosira pseudonana (Baek et al., 2011; Adenan et al., 2013) have distinct ranges of pH and salinity where they will grow (Spaulding et al., 2019). In addition, they have ranges and tolerance for other environmental factors, such as nutrient concentration, suspended sediment, flow regime, elevation, and for different types of human distur­ bances (Spaulding et al., 2019). Hence, they are consid­ ered susceptible indicators of water quality and environ­ mental change. For these reasons, diatoms have received considerable attention from past and ongoing research (Dixit et al., 1992; Adenan et al., 2013; Hilaluddin et al., 2020). In general, diatoms have been discriminated morphologi­ cally by using a light microscope (LM) and scanning elec­ tron microscope (SEM). However, some diatoms may have few discernible structural differences when viewed with a microscope. In addition, different lineages have often adapted in similar ways to analogous habitats. As a result, there are many examples of diatoms species that look very similar at the microscopic level, but are not closely related (Graham et al., 2009). Since the early 1980s, molecular techniques by using carbohydrates, toxins, proteins, and nucleic acids as markers have been developed to detect and discriminate phytoplankton (Ebenezer et al., 2012; Sun et al., 2012). Among DNA based methods such as terminal restriction fragment length polymorphism, micro­ array, real­time PCR, the high­throughput sequencing (HTS) of small­subunit rRNA genes from environmental DNA techniques has already been widely applied for the assessment of microbial diversity and micro­planktonic community structure (Eiler et al., 2012; Ghiglione and Murray, 2012). These methods allowed high resolution and rapid analysis of microbial and phytoplankton com­ Journal of Species Research 10(1):46­56, 2021","PeriodicalId":426231,"journal":{"name":"Journal of species research","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122746758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Euphorbioideae, subfm. Acalyphoideae Beilschm., Cheilosoideae K. Wurdack & Petra Hoffmann, and Crotonoideae Burmeist.) (Govaerts et al., 2000; APG IV, 2016). Members of Euphorbieae are monoecious or dioecious trees, shrubs, or herbs with milky latex, highly specialized inflorescence (cyanthium), superior and tri-locular ovary, and axile placentation (Park and Backlund, 2002; Thakur and Patil, 2011). The plants of this family are mainly distributed in the tropical and subtropical regions with some of native and naturalized species in the temperate regions including Asia, Australia, and North America (Heywood, 1985; Webster, 1986; 1994; Savolainen et al., 2000; Li et al., 2008; APG IV, 2016). A number of Euphorbiaceae species are economically and commercially important as food, ornamental, timber, or raw materials of wax, rubber, and dye (Salatino et al., 2007; Bennett, 2010; Kumar et al., 2010; Elhassan et al., 2015). In particular, many species in the genus Euphorbia are used as medicinal plants, although most of the plants in the genus contain toxic chemicals called diterpenoids (Hohmann and Molnár, 2004; Ernst et al., 2015). Since ancient times, various indigenous species are utilized as medicines for curing skin diseases, intestinal parasites gonorrhea, warts, and migraines on the basis of traditional folk recipes (Singla and Kamla, 1990; Salatino et al., 2007; Bennett, 2010; Kumar et al., 2010; Elhassan et al., 2015). For sustainable utilization of Euphorbiaceae as plant resources, accurate species identification and understanding of their phylogenetic relationships are essential steps (Pang et al., 2010; Aubriot et al., 2013). Although many previous phylogenetic studies were carried on with chloroplast (cp) DNA (atpB, matK, ndhF, rbcL, trnL-F) and/or nuclear (nr) DNA (ITS) loci (Wurdack et al., 2004; 2005; Tokuoka, 2007; Thakur and Patil, 2011; Yang et al., 2012; Aubriot et al., 2013; Riina et al., 2013), these studies only attempted to resolve higher level (family, genus or subgenus) relationships in Euphorbiaceae. Meanwhile, Pang et al. (2009) largely collected DNA sequences of two cpDNA (rbcL, matK) and two nrDNA (ITS1, ITS2) loci of the family Euphorbiaceae from GenBank and evaluated the species identification ability of four barcode loci. Among the four loci, Pang et al. (2009) reported the efficiency of the ITS1 and ITS2 loci for discrimination of species in the Euphorbiaceae famJournal of Species Research 9(4):413-426, 2020","PeriodicalId":426231,"journal":{"name":"Journal of species research","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115986553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since foraminifera are one of the dominant organisms in the benthic environments, and exhibit wide range of feeding mechanisms, they are regarded as one of the key groups in the marine food web (Gooday et al., 1992; Moodley et al., 2000; Debenay, 2012; Chronopoulou et al., 2019). Foraminifera are one of the most sensitive organisms to environmental change and their assemblage is closely related to environmental factors (Murray, 2006; Sabbatini et al., 2012). Therefore, research on diversity and community structure of foraminifera is important for understanding the marine environment (Annin, 2001; Albani et al., 2007). To date, 8,857 species of marine extant foraminifera have been reported worldwide (WoRMS, 2020) and 1,192 species have been reported in Korea (NIBR, 2020). Since the 1,192 species include some of fossil species and synonyms, a clear understanding of species diversity of modern foraminifera in Korea is necessary. In this regard, Kim et al. (2016) documented 818 extant benthic species through a literature survey and emphasized the high possibility of additional discoveries of unrecorded species through further investigations. Indeed, in 2017, 30 unrecorded species were reported from the western and eastern coasts of Korea (Lee et al., 2017), and in 2019, one new species and three newly recorded species were reported from the northern East Sea and southern Jeju Island (Lee and Lee, 2019; Lee et al., 2019).

Subsequently, Grandjean (1936) redefined the type species, and ascer­ tained generic status of Haplozetes and proposed the fam­ ily Haplozetidae (Ermilov et al., 2013). This family is diagnosed by the movable pteromorphs; rostrum round­ ed; lamellae narrow, without translamella; 10­14 pairs of notogastral setae; four to five pairs of genital setae; mono­ or tridactylous legs (Bayartogtokh, 2010).
