Rhyacophila Pictet 1834 is globally distributed and highly diverse genus of caddisflies (Trichoptera), characterized by numerous regionally endemic species. In the Balkan Peninsula, the highest number of Rhyacophila species (23) was recorded for Bosnia and Herzegovina. Rhyacophila bosnica Schmid, 1970 is found only in the Balkan Dinaric region, with a locus typicus in Vučja Luka, Bosnia and Herzegovina. Like with many species of Trichoptera, the morphology of its larva is still unknown. Therefore, DNA barcoding approach was used to link two developmental stages. In this paper, we report on the first DNA barcode record for this species.

This research provides pivotal molecular genetic data on the community structure of aquatic insects from semi-mountainous and mountainous rivers from the 6th Ecoregion that belongs to the territory of North Macedonia. The aim of this research is to fill the gaps for barcoding the aquatic macroinvertebrates from the Balkan Peninsula and check if the existing barcode library could provide improved identifications for the specimens that were not taxonomically determined to the lowest level possible. We analyzed 95 specimens from which total DNA was extracted and the COI barcode region amplified and sequenced. The taxa were selected from 20 different localities of the territory of western part of North Macedonia. The selected specimens were not determined to species-level in order to test the efficiency of the DNA barcoding methodology and what is missing in the DNA barcoding data library. From the result from one plate (95 specimens) we obtained: 16 samples without barodes, or failed and 10 samples did not have a match in the BOLD database. In the remining 69 samples, three were misidentified. In the total of 69 barcoded species new for the fauna of North Macedonia, 11 are mayflies: Baetis melanonyx, Ecdyonurus vitoshensis, E. macani; stonefly Isoperla vjose; and caddisflies: Agapetus delicatulus, Athripsodes bilineatus, Glossosoma klotho, Lepidostoma basale, Helicopsyche bacescui, Tinodes unicolor and Odontocerum hellenicum. We have also four rarely found species: Zwicknia bifrons, Drussus tenellus, Hydropsyche botosaneanui and Hydropsyche bulbifera, and one species without barcode available as Ecdyonurus sp. SK2 (potential new species). We found 83% efficiency of DNA barcoding, where some samples failed or were with low or medium quality for some specimens, as for the representatives from the genera Baetis, Oxietyra and Rhyacophila. In conclusion we can confirm that 10 of the selected vouchers need to be further identified by morphology and to be added in the BOLD barcode library, and maybe we'll have the possibility to describe a new species as well.

Solanaceae Family

The Solanaceae family is one of the largest and well-distributed plant families in the world. It contains species of agricultural and economical importance, such as Solanum tuberosum, Solanum melongena, Solanum lycopersicum, Nicotiana tabacum, and Capsicum annuum. In Puerto Rico, there are ≈46 species of Solanaceae of which six are endemic: Brunfelsia densifolia, Brunfelsia lactea, Brunfelsia portoricensis, Goetzea elegans, Solanum ensifolium, and Solanum woodburyi. Our objective was to use DNA barcoding to identify the Solanaceae species in Puerto Rico, including the endemics, and to assess the species relationships between them. To accomplish our objective, two chloroplast regions (psbA-trnH and matK) and a nuclear region [internal transcribed spacer (ITS)] were assessed. Pairwise distance and phylogenetic analysis demonstrate that DNA barcoding can be used to discriminate at the species level among these taxa in Puerto Rico. For all three markers, the genus that showed the highest pairwise distance between represented species was Solanum, whereas the genus that displayed the least was Capsicum. Phylogenetic trees of single and concatenated regions were generated from sequences obtained in this study and from data downloaded from the National Center for Biotechnology Information database. Our results show that this technique can be used to identify species with one, two, or three combinations of DNA barcode markers depending on the taxon. In addition, this is the first study to include the endemic species S. woodburyi in a molecular phylogenetic analysis, and it was found to have a close relationship with S. ensifolium, also endemic to Puerto Rico, and to Solanum bahamense from the Bahamas and Greater Antilles. Therefore, we suggest that S. woodburyi might be part of the Bahamense clade.

Ecological Importance

Oligochaeta is a class of segmented worms under the phylum Annelida that are characterised by the presence of tiny setae in each body segment. Earthworms are the main members, consisting of approximately 6200 species. Their ecological importance is well known as they are the major soil macro-fauna; Aristotle had named them as “the intestines of soil”. Classification of earthworms is a controversial issue since the introduction of modern taxonomical system on earthworm by Michaelsen in 1921. This is mainly because conventional identification using morphological and anatomical characters are complicated and confusing. The key diagnostic features such as the position and structure of the reproductive organs, clitellum and the associated tubercular pubertatis are not always reliable, particularly in different developmental stages, especially when the available specimens are the juveniles. DNA barcoding has offered a potential solution, even at the levels of identifying the juveniles or cocoons. Several genes including mitochondrial cytochrome-c oxidase I, 16S, 18S and 28S ribosomal RNAs, and protein-coding histone H3 genes have been introduced in the taxonomy and phylogeny of earthworm. It is anticipated that DNA barcoding will help conflicting taxonomy and further exploration of species diversity in India.

Public Data

Bosnia and Herzegovina has valuable natural resources with a high percentage of endemic and autochthonous species (Kučinić et al. 2008, Đug and Drešković 2012). The freshwater fauna of Trichoptera in this area is under-investigated, with a lack of morphological description of different life stages and DNA barcode data. Public data show 58,993 barcode entries for Trichoptera in the Barcode of Life Data Systems (BOLD) submitted from 92 countries, and none from Bosnia and Herzegovina (B&H) (BOLD 2021). Previous research in Bosnia and Herzegovina has provided the first DNA barcode for the endemic species Rhyacophila bosnica, stored in GeneBank, under accession number MK211322 by a domestic institution (Kalamujić Stroil et al. 2018). A few DNA barcodes of adult individuals of Trichoptera from Bosnia and Herzegovina were found in BOLD. However, these specimens were collected on B&H territory, but analyzed, processed, and stored by foreign institutions. To change the current state of DNA barcoding of Trichoptera in Bosnia and Herzegovina, we aimed to employ this approach in investigating caddisflies in selected habitats in the Sarajevo Canton. Our fieldwork was done in all five protected areas (spring of the Bosna River, Bijambare, Trebević, Skakavac, and Bentbaša) in which larvae samples were collected according to the AQEM sampling methodology. The standard animal DNA barcode was successfully obtained using degenerated primers LCO1490- JJ and HCO2198-JJ (Astrin and Stüben 2008). Out of 684 collected individuals (313 Trebević, 130 spring of the Bosna River, 117 Bijambare, 71 Bentbaša, 53 Skakavac), a subset of specimens were sequenced. We uncovered 14 different taxa, 11 genera and six families (Limnephilidae, Glossosomatidae, Rhyacophilidae, Goeridae, Hydropsychidae, Polycentropodidae). The preliminary data of Trichoptera composition in the Sarajevo Canton indicated species richness. Based on our sequential data, a new subspecies was discovered in two investigated areas (Valladolid et al. 2020), proving that Trichoptera species diversity in our country is far from entirely uncovered. The benefit and power of the DNA barcoding approach are that it can pinpoint the areas of vast and unknown species diversity more economically, both financially and temporarily, than the morphological approach. Therefore, we believe that it is critical to support the development of DNA barcoding for the bioassessment of freshwater ecosystems in Bosnia and Herzegovina. Several problems prevented us from exploiting sequential data to the fullest. Despite a general notion among scientists that European Trichoptera species are well covered in the BOLD database, most of the sequences we obtained were absent from the database. Secondly, we recognized that morphological data about the larval developmental stage of B&H Trichoptera species are largely missing. The unified, updated, and complete data on this order of insects is urgently needed. However, insufficient financial support by governmental institutions and lack of systematic approach to barcoding the wildlife of Bosnia and Herzegovina hampers this process. Further attempts to collaborate with the stakeholders can be crucial with profound and substantial implications for biomonitoring of aquatic macroinvertebrates in general. New approaches, such as novel DNA barcoding-based methodology can fill an important gap in our knowledge of Balkan caddisflies haplotypes, lineages, and their diversification and distribution patterns.

AbstractMitragyna speciosa (Korth.) Havil. [MS], or “kratom” in Thai, is the only narcotic species among the four species of Mitragyna in Thailand, which also include Mitragyna diversifolia (Wall. ex G. Don) Havil. [MD], Mitragyna hirsuta Havil. [MH], and Mitragyna rotundifolia (Roxb.) O. Kuntze [MR]. M. speciosa is a tropical tree belonging to the Rubiaceae family and has been prohibited by law in Thailand. However, it has been extensively covered in national and international news, as its abuse has become more popular. M. speciosa is a narcotic plant and has been used as an opium substitute and traditionally used for the treatment of chronic pain and various illnesses. Due to morphological disparities in the genus, the identification of plants in various forms, including fresh leaves, dried leaf powder, and finished products, is difficult. In this study, DNA barcoding combined with high-resolution melting (Bar-HRM) analysis was performed to differentiate M. speciosa from allied Mitragyna and to assess the capability of Bar-HRM assays to identify M. speciosa in suspected kratom or M. speciosa-containing samples. Bar-HRM analysis of PCR amplicons was based on the ITS2, rbcL, trnH-psbA, and matK DNA barcode regions. The melting profiles of ITS2 amplicons were clearly distinct, which enabled the authentication and differentiation of Mitragyna species from allied species. This study reveals that DNA barcoding coupled with HRM is an efficient tool with which to identify M. speciosa and M. speciosa-containing samples and ensure the safety and quality of traditional Thai herbal medicines.

Cacopsylla Melanoneura

The transmission of phytoplasmas is the result of an intricate interplay involving pathogens, insect vectors and host plants. Knowledge of the vector’s competence during its lifespan allows us to define more sustainable well-timed control strategies targeted towards the most worrisome life stages. We investigated the temporal dynamics of ‘Candidatus Phytoplasma mali’ load in Cacopsylla melanoneura in the different developmental stages in Northwest Italy. The phytoplasma load in the vector was evaluated in overwintering adults, nymphs and newly emerged adults after different acquisition access periods. Moreover, we followed the multiplication of the phytoplasma during the aestivation and the overwintering period on conifers. Our results confirmed the ability of remigrants to retain the phytoplasma until the end of winter. We also highlighted the high acquisition efficiency and vector competence, based on phytoplasma load, of nymphs and newly emerged adults. Therefore, particular attention should be paid to the management of overwintered C. melanoneura as soon as they return to the orchards, but also to newly emerged adults, particularly in orchards with a high infection rate and when the migration to conifers is delayed.

Nowadays, the global fish consumption continues to rise along with the continuous growth of the population, which has led to the dilemma of overfishing of fishery resources. Especially high-value fish that are overfished are often replaced by other fish. Therefore, the accurate identification of fish products in the market is a problem worthy of attention. In this study, full-DNA barcoding (FDB) and mini-DNA barcoding (MDB) used to detect the fraud of fish products in Guiyang, Guizhou province in China. The molecular identification results showed that 39 of the 191 samples were not consistent with the labels. The mislabelling of fish products for fresh, frozen, cooked and canned were 11.70%, 20.00%, 34.09% and 50.00%, respectively. The average kimura 2 parameter distances of MDB within species and genera were 0.27% and 5.41%, respectively; while average distances of FDB were 0.17% within species and 6.17% within genera. In this study, commercial fraud is noticeable, most of the high-priced fish were replaced of low-priced fish with a similar feature. Our study indicated that DNA barcoding is a valid tool for the identification of fish products and that it allows an idea of conservation and monitoring efforts, while confirming the MDB as a reliable tool for fish products.

Abstract Background: The internal transcribed spacer (ITS) of nuclear ribosomal DNA is one of the most commonly used DNA markers in plant phylogenetic and DNA barcoding analyses, and it has been recommended as a core plant DNA barcode. To compare and find out the analysis genetic diversity difference some pepper individuals collected in different localities in Vietnam when using the ITS of nuclear ribosomal DNA. The ITS gene region from the nuclear genomes were tested for their suitability as DNA barcoding regions of thirty-nine pepper individuals. Universal primers were used, and sequenced products were analyzed using the Maximum Likelihood method and Tamura-Nei model in the MEGA X program.Results: We did not observe high variability in intraspecific distance within the ITSu1-4 gene region between individuals, ranged from 0.000 to 0.155 (mean = 0.033). The size of the gene region has fluctuated from 667 to 685 bp between different individuals with the percentage (G + C) contained in the ITSu1-4 gene region was ranged from 54.776% to 60.805%, mean = 60.174%. The values of Fu’s Fs, D, Fu and Li’s D* and F* were negative as well (Fs = -0.209, D = -1.824; P < 0.05, D* = -1.205; not significant, P > 0.10 and F* = -1.699; not significant, 0.10 > P > 0.05), indicating an excess of recently derived haplotypes and suggesting that either population expansion or background selection has occurred. The value Strobeck’s S the obtained between individuals in a population is high (S = 0.684). The results of evolutionary relationships of taxa obtained 3 groups with the highest value of Fst is shown in the pairs of groups II and III (Fst = 0.151), and the lowest is in groups II and I (Fst = 0.015). All of the new sequences have been deposited in GeneBank under the following accession numbers MZ636718 to MZ636756.Conclusions: This database is an important resource for researchers working on Species of pepper in Vietnam and also provides a tool to create ITSu1-4 databases for any given taxonomy.

<p>This thesis focuses on the role of an international actor - United Nations (UN) - and its missions in Bosnia and Herzegovina (UNMBiH) during 1992-1995 and Kosovo (UNMIK) in the post war conflict period of peace building. It scrutinizes the tenor of UN peace building missions in these territories by analysing the scope of the policies introduced and the effectiveness (or ineffectiveness) of the international actors' activities during the times of war in Bosnia and Herzegovina (BiH) before the conflict in Kosovo and Metohija (KiM); and the current situation in these two territories. The thesis will also argue that the ethnic identities played a critical role in relation building between the UN and ethnic groups, where the one ethnic group (Serbs) was recognised as a crucial factor for the conflict's escalation and development. A further focus in this thesis is not only to provide constructive discussion of the ineffectiveness of policies and missions introduced by International Actors (IA) but also to challenge the UN and IA's decision for non-intervention in BiH and to address the consequence of subsequent humanitarian-military intervention in KiM. This paper outlines an analysis of the lack of literature relating to the historical-sociological perspective of the ethnic groups' in BiH. The lack of understanding of the complex relationships among the ethnicities is an additional gap. This is exacerbated by the lack of understanding of the complex relationships among the ethnicities, within itself, as well as the differences among the groups within each ethnic group. It appears that the literature is unable to acknowledge the structural formation of societies in BiH, and to make proper segmentation in understanding the particular group of people (Rex, 2001) as a collection of peoples with different sociological characteristics combined into something called 'ethnicity'. The handicap of such literature leads to the categorisation and generalisation of ethnicities; not at one particular area of an ethnic group's presence but to the generalisation of the peoples' ethnicities (all Serbs are barbarous, similar to the Germans after WWII). This paper argues that such generalisations developed the notion that the particular ethnic group (Serbs) has an 'evil' character, regardless of the territorial occupation (Bosnia as well as Serbia and Diaspora). In addition, the lack of recognising Serbs as a people composed of different individual (local) ethnic groups led to the global generalisation about Serbs. And yet, such generalisations, by the modern western actors, i.e. UN, EU (European Union) and USA (United States of America), led to the employment of negative assumptions about the Serbs which served as a tool for, and added impetus to, the implementation of a strategy to achieve the Western objectives of the devaluation of Serbian dominance in Bosnia and across the Balkan Peninsula. Therefore the quality of literature, in addressing the questions about the conflict in BiH and later KiM, beside its attempts to offer some sustainable answers, remains inadequate and poor. This unsubstantiated position, offered by many involved in former-Yugoslavian conflict discussions, to offer an informed conclusion, persists as a never-ending debate. Yet, the discourse about the guilty factor in BiH and KiM remains in the shape of the 'evil' Serbian nation.</p>

Background and Study Aim: The aim of this research was to determine the differences between the young soccer players (U19) in terms of anthropometric characteristics and body composition. We considered players of three the most successful clubs in three countries of the southern region of the Balkan Peninsula. Material and Methods: The first sub-sample of the subjects was consisted of 17 players of OFC Titograd from Montenegro of the average age 17.12±.69. The second sub-sample was consisted of 14 players of FC Siroki Brijeg from Bosnia and Herzegovina of the average age of 18.14±.86. The last sub-sample of the examinees was consisted of 15 players of FC Feronikeli from Kosovo of the average age 18.07±.46. Anthropometric characteristics in the body composition were evaluated by a battery of 11 variables. The significance of the differences between the young soccer players in the anthropometric characteristics and variables for assessing body composition were determined by ANOVA and LSD Post Hoc test. Results: The young soccer players of the three mentioned clubs have statistically significant differences by the two variables that estimate the upper leg skinfold and fat percentage. The young soccer players of OFC Titograd are significantly better in variable upper leg skinfold than other players. The young soccer players of FC Feronikeli are significantly better in variable fat percentage than players of OFC Titograd. Conclusions: The results can be useful for coaches of other clubs for making a comparison of their soccer players with the young soccer players in this research.
