An ethnobotany of the Lukomir Highlanders of Bosnia & Herzegovina

Background

This aim of this study is to report upon traditional knowledge and use of wild medicinal plants by the Highlanders of Lukomir, Bjela?nica, Bosnia and Herzegovina (B&H). The Highlanders are an indigenous community of approximately 60 transhumant pastoralist families who speak Bosnian (Bosanski) and inhabit a highly biodiverse region of Europe. This paper adds to the growing record of traditional use of wild plants within isolated communities in the Balkans.

Methods

An ethnobotanical study using consensus methodology was conducted in Lukomir in Bjela?nica’s mountains and canyons. Field work involved individual semi-structured interviews during which informants described plants, natural product remedies, and preparation methods on field trips, garden tours, while shepherding, or in settings of their choice. Plant use categories were ranked with informant consensus factor and incorporated into a phylogenetic tree. Plants cited were compared to other ethnobotanical surveys of the country.

Results

Twenty five people were interviewed, resulting in identification of 58 species (including two subspecies) from 35 families, which were cited in 307 medicinal, 40 food, and seven material use reports. Individual plant uses had an average consensus of five and a maximum consensus of 15 out of 25. There were a number of rare and endangered species used as poisons or medicine that are endemic to Flora Europaea and found in Lukomir. Ten species (including subspecies) cited in our research have not previously been reported in the systematic ethnobotanical surveys of medicinal plant use in B&H: (Elymus repens (L.) Gould, Euphorbia myrsinites L., Jovibarba hirta (L.) Opiz, Lilium bosniacum (Beck) Fritsch, Matricaria matricarioides (Less.) Porter ex Britton, Phyllitis scolopendrium (L.) Newman, Rubus saxatilis L., Silene uniflora Roth ssp. glareosa (Jord.) Chater & Walters, Silene uniflora Roth ssp. prostrata (Gaudin) Chater & Walters, Smyrnium perfoliatum L.). New uses not reported in any of the aforementioned systematic surveys were cited for a total of 28 species. Thirteen percent of medicinal plants cited are endemic: Helleborus odorus Waldst. et Kit., Gentiana lutea L., Lilium bosniacum (Beck) Fritsch, Silene uniflora Roth ssp. glareosa (Jord.) Chater & Walters., Silene uniflora Roth ssp. prostrata (Gaudin) Chater & Walters, Salvia officinalis L., Jovibarba hirta (L.) Opiz, and Satureja montana L.

Conclusions

These results report on the cohesive tradition of medicinal plant use among healers in Lukomir, Bosnia and Herzegovina. This work facilitates the community’s development by facilitating local and international conversations about their traditional medicine and sharing insight for conservation in one of Europe’s most diverse endemic floristic regions, stewarded by one of Europe’s last traditional Highland peoples.

     

The uses of Kenyan aloes: an analysis of implications for names,distribution and conservation

Background

The genus Aloe is renowned for its medicinal and cosmetic properties and long history of use. Sixty-three Aloe species occur in Kenya, of which around 50 % are endemic. Several species of aloes are threatened with extinction and knowledge about their use is of major importance for sound conservation strategies. The main aims of this study were to assess the biocultural value of Aloe in Kenya by documenting local uses of aloes and evaluating how the vernacular names reflect the relative importance in different ethnic groups.

Methods

Ethnobotanical and ethnotaxonomical data were collected using field observations and semi-structured interviews. Information was collected by interviewing 63 respondents from nine different ethnic groups, representing different ages, gender and occupations. Statistical analyses were performed using R version 3.1.2.

Results

A total of 19 species of Aloe were found in the study area, of which 16 were used. On the generic level Aloe was easily distinguished. At species level, the local and scientific delimitation were almost identical for frequently used taxa. Aloe secundiflora, with 57 unique use records was the most important species. The two most frequently mentioned Aloe treatments, were malaria and poultry diseases. In our study area neither age nor gender had a significant influence on the level of knowledge of Aloe use. Finally, no correlation was found between extent of use and people’s perception of decrease in local aloe populations. The aloes are highly appreciated and are therefore propagated and transported over large areas when people relocate.

Conclusion

Biocultural value is reflected in the ethnotaxonomy of Aloe in Kenya. Different ethnic groups recognise their most-valued Aloe at the genus level as “the aloe” and add explanatory names for the other species, such as the “spotted aloe” and the “one-legged aloe”. Widespread species of Aloe have the highest number of uses. There is no obvious correlation with high use and decrease in abundance of aloes locally, and we found no compelling evidence for local uses causing devastating damage to populations of the 19 species in use, whereas habitat loss and commercial harvesting appear to be of urgent concern for these important plants.

     

Vertebrates as a Bactericidal Agent

In Brazil, although a large number of animals are used in traditional medicine (at least 354 species), information about their biological activities is scarce. In this context, the objective of this study was to evaluate the bactericidal potential of zootherapeutic by-products from animals used in Brazilian traditional medicine and discuss the ecological and cultural consequences of such practices. The species analyzed were: Tupinambis merianae (skin), Iguana iguana (skin and body fat), Crotalus durissus (skin and body fat), Boa constrictor (skin), Euphractus sexcinctus (body fat) and Coendou prehensilis (quills). Experiments were performed with standard clinical strains of Escherichia coli (EC-ATCC10536) and Staphylococcus aureus (SA-ATCC 25923). For the microbiological assay, the zootherapeutics were evaluated using serial microdilutions. The results indicate that none of the samples possess inhibitory activity against standard bacterial strains. The in vitro ineffectiveness of the analyzed products demonstrate a necessity for new pharmacological research that encompass a large number of species of medicinal animals as well as highlight the importance of zootherapy in the context of plans for animal conservation.     

Commercialization of Andean Wild Yam Species (<Emphasis Type="Italic">Dioscorea</Emphasis> L.) for Medicinal Use in Bogotá, D.C., Colombia

Commercial exploitation of wild yams (Dioscorea spp.) was once a pillar of the Mexican economy and is currently practiced in the USA and Asia. However, no such activity has yet been reported in South America, the continent richest in Dioscorea species. Upon discovery of wild Dioscorea tubers in marketplaces in Bogotá, Colombia, we sought to (1) identify the species being sold, (2) document the medicinal properties attributed to them, and (3) conduct a preliminary characterization of the market for this product in the capital. During the years 2010, 2012, and 2013, 226 semi-structured interviews were conducted with vendors in 82 medicinal plant stalls distributed in marketplaces throughout Bogotá. Tubers of four native species were identified, all wild-harvested: D ioscorea coriacea, Dioscorea lehmannii, Dioscorea meridensis, and Dioscorea polygonoides; all were sold under the generic name zarzaparrilla, with D. coriacea being the most prevalent species. All vendors interviewed recommended Dioscorea spp. for treating “ailments of the blood,” with “blood cleanser,” and lowering triglycerides and cholesterol as the most often-cited specific uses. Total estimates of sales of wild yams over the study period averaged 488 kg/week, extrapolated to over 25,000 kg/year, with yearly sales varying between 5% and 6% around the mean. This is the first report of raw tubers of any Dioscorea species being commercialized for the treatment of blood or metabolic disorders in Latin America, and the data suggest there is a robust market established in Bogotá. In the interest of public health, pharmacological studies should be undertaken to test the biological activity of these species and to rule out toxicity. We especially recommend population studies of D. coriacea to provide baseline data for sustainable management of this non-timber forest product.     

Ethnobotanical survey of cosmetic plants used in Marquesas Islands (French Polynesia)

Background

Cosmetic plants and their uses have often been neglected in ethnobotanical surveys which focus mainly on plants with medicinal or food uses. Thus, this survey was carried out to specifically investigate cosmetics in a small community and to establish a cosmetopoeia, based on the model of pharmacopoeia for medicinal plants. The geographic spread of the survey covered the Marquesas Islands, one of the five archipelagos of French Polynesia (Pacific Ocean). This archipelago was also recently investigated for its pharmacopoeia.

Methods

This survey is based on individual interviews of Marquesan informants on the islands of Tahiti (Society archipelago) and Nuku Hiva (Marquesas archipelago). The methodological approach was semi-directive with open-ended questions based on cosmetic criteria (application area, cosmetic use, plant). Before each interview, researchers and the informant signed a Prior Informed Consent (PIC). Quantitative analyses were performed using basic statistics and the indice of Fidelity Level (FL).

Results

Twenty-eight informants from five of the six inhabited Marquesan islands were interviewed and yielded more than 500 cosmetic recipes. Marquesan cosmetopoeia included 79 plant taxa, of which 5% are Marquesan endemics, 23% are indigenous, 28% are Polynesian introductions and 44% are modern introductions. Among the introduced species, half were cultivated whereas the other half were weedy species. Most of the plants were abundant and only eight species were considered rare, of which four were Marquesan endemics. Main cosmetic plants were identified through informant citations and fidelity levels, and included Calophyllum inophyllum, Cananga odorata, Citrus aurantiifolia, Cocos nucifera, Curcuma longa, Gardenia taitensis, Mentha spp., Ocimum basilicum, Rauvolfia nukuhivensis and Santalum insulare var. marchionense. The most referred application areas were skin, hair and private parts whereas the main cosmetic uses were perfume, hydration, medicinal care and healing.

Conclusions

Through this survey, Marquesan cosmetopoeia was investigated in detail and uncovered a majority of introduced and abundant plants, and a minority of endemic and rare plants which required proper management to avoid future shortage. The well known perfumed coconut oil or monoi appeared as the main Marquesan cosmetic preparation either for the skin and the hair. Several plants and preparations warrant scientific investigations for their originality.

     

Snake fauna (Reptilia: Serpentes) from the Early/Middle Miocene of Sandelzhausen and Rothenstein 13 (Germany)

The Early/Middle Miocene (European Land Mammal Zone MN5) localities of Sandelzhausen and Rothenstein 13 in southern Germany have yielded remains of about 13 ophidian taxa: Eoanilius sp. (Aniliidae), Bavarioboa ultima (Boidae), “Coluber” sp., ?Telescopus sp., Natrix sp., cf. Natrix sp., cf. “Neonatrix” sp., unidentified “colubrines” and “natricines” (Colubridae), Naja sp., an unidentified elapid (Elapidae), Vipera sp. (“Oriental viper”), Vipera sp. (“aspis complex”) (Viperidae). Both faunas document a transitional phase from those reported from several late Early and Middle Miocene sites of Central and Western Europe. The climates of Sandelzhausen and Rothenstein 13, as indicated by ophidian fossils, were warm, although not tropical or subtropical.     

Hypercalcified segmented sponges (“sphinctozoans”) from the Upper Triassic (Norian) reef boulders of Taurus Mountains (southern Turkey)

Upper Triassic Norian reef boulders, exposed in a locality near the fountain “Tavuk Cesme” (“Chicken Fountain”) in Taurus Mountains, southern Turkey yielded a large number of hypercalcified sponges, including “sphinctozoans”, “inozoans”, “spongiomorphids”, and “chaetetids”. The sphinctozoans from this locality are described in this paper. Geologically, this locality belongs to the Anamas-Akseki autochthonous. The reef boulders of this locality are exposed near the “Tavuk Cesme” fountain, located at the road, leading from the town of Aksu to Yenisarbademli. The following taxa are described: Amblysiphonella taurica nov. sp., Anthalythalamia riedeli Senowbari-Daryan, Calabrisiphonella sphaerica nov. sp., Calabrisiphonella cuifi nov. sp., Cinnabaria minima Senowbari-Daryan, Colospongia recta nov. sp., Colospongia sp. 1, Colospongia sp. 2, Colospongia sp. 3, Cryptocoelia compacta nov. sp., Cryptocoelia? sp., Deningeria crassireticulata Senowbari-Daryan, Zühlke, Bechstädt and Flügel, Discosiphonella minima Senowbari-Daryan and Link, Gigantothalamia ovoidalis Senowbari-Daryan, Hajarispongia dipoyrazensis nov. sp., Hajarispongia cortexifera nov. sp., Kashanella irregularis Senowbari-Daryan, Kashanella cylindrica nov. sp., Parauvanella ferdowsensis Senowbari-Daryan, Parastylothalamia cylindrica nov. gen., nov. sp., Asiphothalamia polyosculata nov. gen, nov. sp., Sollasia norica nov. sp., and Thaumastocoelia sphaeroida Senowbari-Daryan. The most abundant sponge is Amblysiphonella taurica nov. sp. followed by Hajarispongia dipoyrazensis nov. sp., Colospongia and Discosiphonella minima Senowbari-Daryan and Link are also relatively abundant. The stylothalamid sponge Parastylothalamia nov. gen. is an abundant sponge genus in other Norian reefs of the Taurus Mountains, but is rare at the “Tavuk Cesme” locality.     

High-throughput sequencing of <Emphasis Type="Italic">Prunus ferganensis</Emphasis> indicates that it is a geographical population of <Emphasis Type="Italic">P. persica</Emphasis>

Peach belongs to the genus Prunus, which includes Prunus persica and its relative species, P. mira, P. davidiana, P. kansuensis, and P. ferganensis. Of these, P. ferganensis have been classified as a species, subspecies, or geographical population of P. persica. To explore the genetic difference between P. ferganensis and P. persica, high-throughput sequencing was used in different peach accessions belonging to different species. First, low-depth sequencing data of peach accessions belonging to four categories revealed that similarity between P. ferganensis and P. persica was similar to that between P. persica accessions from different geographical populations. Then, to further detect the genomic variation in P. ferganensis, the P. ferganensis accession “Xinjiang Pan Tao 1” and the P. persica accession “Xia Miao 1” were sequenced with high depth, and sequence reads were assembled. The results showed that the collinearity of “Xinjiang Pan Tao 1” with the reference genome “Lovell” was higher than that of “Xia Miao 1” and “Lovell” peach. Additionally, the number of genetic variants, including single nucleotide polymorphisms (SNPs), structural variations (SVs), and the specific genes annotated from unmapped sequence in “Xia Miao 1” was higher than that in “Xinjiang Pan Tao 1” peach. The data showed that there was a close distance between “Xinjiang Pan Tao 1” (P. ferganensis) and reference genome which belong to P. persica, comparing “Xia Miao 1” (P. persica) and reference ones. The results accompany with phylogenetic tree and structure analysis confirmed that P. ferganensis should be considered as a geographic population of P. persica rather than a subspecies or a distinct species. Furthermore, gene ontology analysis was performed using the gene comprising large-effect variation to understand the phenotypic difference between two accessions. The result revealed that the pathways of gene function affected by SVs but SNPs and insertion-deletions markedly differed between the two peach accessions.     

Optimal choice of a reference electrode for EEG recording

We have studied topographical differences in averaged EEG amplitudes in alpha domain recorded in 10–20 system during “eyes closed” test. These differences appeared due to the use of 13 reference schemes: top and bottom of the chin (P1, P2); nose (N); top and bottom of the back of the neck (Sh1, Sh2); upper back (C); united electrodes at the base of the neck anteriorly and posteriorly (2Sh); united, ipsilateral, and individual ear electrodes (A12, Sym, A1, A2); vertex (Cz); and averaged reference (AR). Six experiments for each of the ten subjects were carried out with grounded and ungrounded states of three distant basic references P2, C, and 2Sh. Pairwise comparisons of topographic consistency of 13 reference schemes were carried out on the proposed complex of three independent indicators with evaluative criterion, followed by centroid-based clustering of the reference schemes and its discriminant verification. As a result, we have established (1) that most coordinated topography is provided by the following reference electrodes—A12, P1, P2, Sym; (2) reference electrodes A1, Sh2, A2, Sh1, AR, Cz are characterized by individually varying topography, which may lead to contradictory conclusions obtained when they are used; (3) no significant reasons have been found for preferring a grounded (neutral) states of reference electrodes, that makes the search for or mathematical construct of an infinitely remote neutral reference electrode less important.     

Genetic Diversity,Genotype Discrimination,and Population Structure of Mexican <Emphasis Type="Italic">Opuntia</Emphasis> sp., Determined by SSR Markers

The Opuntia (prickly pear) genus, an important horticultural crop in Mexico, is essentially a fruit crop with two variants: sweet (“tunas”) or acid (“xoconostles”) fruits; it is also a source of vegetables “nopalitos” or fodder for livestock, among other uses. Its taxonomical classification has been reported as complex, although few studies on the genetic structure of Mexican Opuntia are available, and genetic differences between the two types of fruits are unknown. Opuntia genotype identification and classification are still mainly based on morphological characters. In this study, the genetic diversity of Mexican Opuntia germplasm with agronomic and economic importance was revealed, using 88 accessions and 13 SSR markers, in an attempt to explore the genetic relationships among them. A total of 159 alleles were detected ranging from 7 to 23 per locus with an average of 12.2. The SSR markers generated unique fingerprints for each Opuntia accession confirming their usefulness for genetic analysis. The accessions’ grouping was defined by several complementary clustering methods, and the moderate incongruences between the different methods did not influence the overall clustering. DAPC and STRUCTURE analyses grouped the accessions into five groups, thus confirming the incorrect delimitation of species in this genus. The following species had no clear boundaries: Opuntia ficus-indica, Opuntia albicarpa, Opuntia megacantha, Opuntia streptacantha, Opuntia lasiacantha, and Opuntia hyptiacantha. However, Opuntia robusta was separated from the rest of the species. Opuntia joconostle and Opuntia matudae, which produce acid fruits, tended to differ from the others. Median-joining simulation classified all genotypes into a complex network, and both linear and reticular ties between Mexican Opuntia genotypes were revealed. The genetic distance revealed in the present study shows the importance of Mexican accessions for conservation and use in breeding programs.     

Ethnopharmacological studies of indigenous plants in Kel village,Neelum Valley,Azad Kashmir,Pakistan

Background

This explorative study was undertaken for the first time in Kel village located in the Upper Neelum Valley, Azad Kashmir, Pakistan. The purpose was to document the indigenous knowledge of the native people used in the preparation of herbal medicines.

Methods

To get the data on traditional uses of medicinal plants, 20 informants were interviewed. Quantitative ethnobotanical indices, i.e., use value (UV), relative frequencies of citation (RFC), informant consensus factor (Fic), fidelity level (FL), data matrix ranking (DMR), preference ranking (PR), and jaccard index (JI), were calculated for the recorded medicinal plants.

Results

A total of 50 medicinal plants belonging to 33 families used in 13 disease categories were documented. Leaves were the frequently used plant parts, and decoction was the commonly used method for herbal medicine. Plants with high use value were Berberis lycium (2.05), Impatiens glandulifera (1.95), Artemisia scoparia (1.75), Ageratum conozoides (1.75), and Achillea millefolium (1.7). The highest RFC value was calculated for Berberis lycium (0.75), Cynoglossum lanceolatum (0.65), and Impatiens glandulifera and Achillea millefolium (0.60 each). The maximum informant consensus factor was for urinary system, cardiac diseases, baldness, and abortion and miscarriage (1.00). Berberis lyceum (95%) used in jaundice, hepatitis, typhoid, fever, and tuberculosis disorders. Plants with maximum fidelity level (FL) were Berberis lycium (95%) followed by Dioscorea bulbifera, Impatiens glandulifera, and Artemisia vulgaris (90%). Olea ferruginea was the most multipurpose plant and exports (21.2%) was the leading threat in the area. The pearson correlation coefficient (0.500) showed a positive correlation between the use value and relative frequency of citation.

Conclusion

The present study provides useful information about traditional uses of medicinal plants used by local communities in different ailments. The plants with the highest use values could be employed in pharmacological research and biotechnological approaches in order to achieve adequate revenue. Some of the plants in the study area are facing high threats of becoming rare, and conservation initiatives are needed to conserve them for sustainable management in the region.

     

Scented grasses in Norway—identity and uses

Background

Some grass species are richer in coumarin and thus more sweetly scented than others. These have been eagerly sought after in parts of Norway, but the tradition has been weakly documented, both in terms of the species collected, their vernacular names, and uses.

Methods

Based on literature data and a substantial body of information collected during my own ethnobotanical field work, artefacts and voucher specimens, the grass species are identified, and their uses clarified.

Results

In Norwegian literature, the tradition of collecting and using scented grasses has received little attention, and past authors largely refer it to Anthoxanthum spp. The tradition’s concentration to the Sámi strongholds of northernmost Norway, and most authors’ lacking knowledge of the Sámi language, have contributed to the weak and misleading coverage in previous publications. Coumarin-rich grass species are well known in folk tradition in northernmost Norway, as luktegress (Norwegian, “scent grass”), háissasuoidni (North Sámi, “scent grass”), hajuheinä (Finnish, “scent grass”), or similar terms. They have been (and still are) frequently collected, and used as perfume, for storing with clothes, and a number of other purposes. Despite literature records identifying the species used as Anthoxanthum odoratum coll. (including A. nipponicum), the main source utilized in North Norway is Hierochloë odorata, both ssp. arctica and ssp. odorata. Anthoxanthum nipponicum and Milium effusum are alternative, but infrequently used sources of material, depending on local tradition and availability.

Conclusion

By far the most important grass species hiding behind the “scented grass” tradition in Norway is Hierochloë odorata. Anthoxanthum nipponicum is also used, but much less frequently, and only a single record confirms the use of Milium effusum. Only the foliage of Hierochloë provides suitable material for making traditional braids. The three major ethnic groups in Norway have all utilized scented grasses as perfume and for storing with clothes, but the tradition’s geographical concentration to the far north of Norway (Finnmark and NE Troms), suggests that it has originally mainly been a Sámi tradition, adopted by their neighbours.

     

Association between chronological depressive changes and physical symptoms in postoperative pancreatic cancer patients

Background

Pancreatic cancer (PC) has poorer prognosis and higher surgical invasiveness than many other cancers, with associated psychiatric symptoms including depression and anxiety. Perioperative depression has not been investigated in PC patients regarding surgical stress and relevant interventions.

Methods

We evaluated chronological depressive changes and subjective physical symptoms in surgically treated PC patients preoperatively and at 3 and 6 months postoperatively.Enrolled patients undergoing pancreatic tumor surgery completed questionnaires based on the Self-Rating Depression Scale (SDS) and Functional Assessment of Cancer Therapy for Patients with Hepatobiliary Cancer (FACT-Hep) preoperatively, and at 3 and 6 months postoperatively. Responses were analyzed with JMP® Pro using one-way and two-way ANOVA, Spearman’s rank correlation coefficient, and multiple regression analysis.

Results

Malignancy was diagnosed in 73 of 101 patients postoperatively; SDS score was significantly higher in these patients than in those with benign tumors at all timepoints: malignant/benign, 41.8/37.9 preoperatively (p?=?0.004); 43.5/37.8 3 months postoperatively (p?=?0.006); and 42.9/37.7 6 months postoperatively (p?=?0.020). SDS scores were significantly higher in patients <?65 years old with malignancy at 3 months than at 6 months postoperatively (44.6/42.5, p?=?0.046) and in patients with malignancy who underwent pancreaticoduodenectomy at 3 months postoperatively than preoperatively (43.4/41.1; p?=?0.028). SDS scores moderately correlated with 8 physical symptom-related FACT-Hep items 3 months postoperatively (p?<?0.05), showing low-to-moderate correlation with 16 physical symptom-related FACT-Hep items at 6 months postoperatively (p?<?0.05). Multiple regression analysis of FACT-Hep symptoms significantly correlated with SDS scores revealed the following significant variables: “lack of energy” (p?<?0.000) and “pain” (p?=?0.018) preoperatively (R²?=?0.43); “able to perform usual activities” (p?=?0.031) and “lack of energy” (p?<?0.000) at 3 months postoperatively (R²?=?0.51); and “stomach swelling or cramps” (p?=?0.034) and “bowel control” (p?=?0.049) at 6 months postoperatively (R²?=?0.52).

Conclusions

PC patients experience persistently high levels of depression preoperatively through 6 months postoperatively, with associated subjective symptoms including pain and gastrointestinal symptoms.

Genetic structure of diploid-polyploid complex of spined loach genus <Emphasis Type="Italic">Cobitis</Emphasis> (<Emphasis Type="Italic">Cypriniformes,Cobitidae</Emphasis>) in the Lower Danube

The extremely high diversity of spined loach biotypes in the Lower Danube has been detected by biochemical genetic investigation and cytometric analysis of 358 specimens collected in the riverbed and shallow channels. Along with two diploid species (C. elongatoides and C. “tanaitica”), six hybrid forms were revealed, namely, diploid C. elongatoides-“tanaitica”; triploid C. 2 elongatoides-“tanaitica,” C. elongatoides-2 “tanaitica,” and C. 2 elongatoides-species-1; and tetraploid C. 3 elongatoides-“tanaitica” and C. elongatoides-species-2-2 “tanaitica.” In addition, specimens with recombinant genotypes were also found. In spite of the apomictic mode of reproduction, the polyploids did not possess clonal structure, but according to the level of polymorphism and the genotype distribution, they were isomorphous to parental diploid species. Thus, in contrast to the polyploidy in Cobitids of the Dnieper, which have appeared in the basin due to the expansion, the polyploids of the Lower Danube are autochthonous and were derived by crossing with local diploid species. The process is apparently proceeds without any limitations.     

Genome-wide identification and expression analysis of the molecular chaperone binding protein <Emphasis Type="Italic">BiP</Emphasis> genes in <Emphasis Type="Italic">Citrus</Emphasis>

Here, we report for the first time the genome-wide identification and expression analysis of the molecular chaperone BiP genes in Citrus. Six genes encoding the conserved protein domain family GPR78/BiP/KAR2 were identified in the genome of Citrus sinensis and C. clementina. Two of them, named here as CsBiP1 and CsBiP2, were classified as true BiPs based on their deduced amino acid sequences. Alignment of the deduced amino acid sequences of CsBiP1 and CsBiP2 with BiP homologs from soybean and Arabidopsis showed that they contain all the conserved functional motifs of BiPs. Analysis of the promoter region of CsBiPs revealed the existence of cis-acting regulatory sequences involved in abiotic, heat-shock, and endoplasmic reticulum (ER) stress responses. Publicly available RNA-seq data indicated that CsBiP1 is abundantly expressed in leaf, flower, fruit, and callus, whereas CsBiP2 expression is rarely detected in any tissues under normal conditions. Comparative quantitative real-time PCR (qPCR) analysis of expression of these genes between C. sinensis grafted on the drought-tolerant “Rangpur” lime (C. limonia) and -sensitive “Flying Dragon” trifoliate orange (Poncirus trifoliata) rootstocks showed that CsBiP1 was upregulated by drought stress on the former but downregulated on the latter, whereas the CsBiP2 mRNA levels were downregulated on drought-stressed “Flying Dragon,” but remained constant on “Rangpur.” CsBiP2 upregulation was only observed in C. sinensis seedlings subjected to osmotic and cold treatments. Taken together, these results indicate the existence of two highly conserved BiP genes in Citrus that are differentially regulated in the different tissues and in response to abiotic stresses.     

Biotic Interactions between Two Species of Microalgae in Mixed Culture

Biotic interactions in a mixed culture of two microalgae species—Scenedesmus quadricauda (Turp.) Breb. and Monoraphidium arcuatum (Korsch.) Hind.—used in bioassay in monocultures as test objects were studied. The toxic effect of cell-free filtrates from different “age” monoculture (2, 7, 10, 15, 21, and 28 days) of S. quadricauda on the growth of the “young” test culture of M. arcuatum and, conversely, the toxic effect of cell-free filtrates from the different “age” (2, 7, 10, 15, 21, and 28 days) monoculture of M. arcuatum on the growth of the “young” test culture of S. quadricauda was evaluated. Simultaneously, the toxicity of their own filtrates of different “ages” was monitored by a test culture of each species. The interactions of the species in the mixed culture can be regarded as negative, as an antagonistic one, when both populations inhibit the growth of each other through metabolites and food resource competition, while the effect of S. quadricauda on M. arcuatum is much stronger. The main factor constraining the growth of monoculture S. quadricauda is the rapid depletion of the food resource from the medium and not the inhibition of growth by its own metabolites. The depletion of the food resources from the medium in monoculture of M. arcuatum occurs much later than in monoculture of S. quadricauda. Metabolites of S. quadricauda cause a strong inhibitory effect on the growth of M. arcuatum, and the metabolites of M. arcuatum cause a weak inhibitory effect on the growth of S. quadricauda. The filtrates of the “old” culture of S. quadricauda (21–28 days) cause the greatest inhibitory effect on cell division of M. arcuatum. The filtrates of the “old” culture of S. quadricauda (21–28 days) cause the greatest inhibitory effect on cell division of M. arcuatum. Comparative analysis of the cell number dynamics of two species, S. quadricauda and M. arcuatum, in mono- and two-species algal cultures, as well as experiments with filtrates of these monocultures, showed that the interaction of species can be explained by the food resource competition and allelopathic interaction (exometabolite effect).     

Botanical ethnoveterinary therapies in three districts of the Lesser Himalayas of Pakistan

Background

Ethnoveterinary knowledge is highly significant for persistence of traditional community-based approaches to veterinary care. This is of particular importance in the context of developing and emerging countries, where animal health (that of livestock, especially) is crucial to local economies and food security. The current survey documents the traditional veterinary uses of medicinal plants in the Lesser Himalayas-Pakistan.

Methods

Data were collected through interviews, focus groups, participant observation, and by administering questionnaires. A total of 105 informants aged between 20–75 years old who were familiar with livestock health issues (i.e. farmers, shepherds, housewives and herbalists) participated in the study.

Results

A total of 89 botanical taxa, belonging to 46 families, were reported to have ethnoveterinary applications. The most quoted families were Poaceae (6 taxa), Fabaceae (6), Asteraceae (5), and Polygonaceae (5). Adhatoda vasica was the most cited species (43%), followed by Trachyspermum ammi (37%), and Zanthoxylum armatum var. armatum (36%). About 126 medications were recorded against more than 50 veterinary conditions grouped into seven categories. The highest cultural index values were recorded for Trachyspermum ammi, Curcuma longa, Melia azedarach, Zanthoxylum armatum var. armatum and Adhatoda vasica. The highest informant consensus factor was found for pathologies related to respiratory and reproductive disorders. Comparison with the local plant-based remedies used in human folk medicine revealed that many of remedies were used in similar ways in local human phytotherapy. Comparison with other field surveys conducted in surrounding areas demonstrated that approximately one-half of the recorded plants uses are novel to the ethnoveterinary literature of the Himalayas.

Conclusion

The current survey shows a remarkable resilience of ethnoveterinary botanical knowledge in the study area. Most of the species reported for ethnoveterinary applications are wild and under threat. Thus, not only is it imperative to conserve traditional local knowledge of folk veterinary therapies for bio-cultural conservation motives, but also to assist with in-situ and ex-situ environmental conservation initiatives, which are urgently needed. Future studies that focus on the validation of efficacy of these ethnoveterinary remedies can help to substantiate emic concepts regarding the management of animal health care and for rural development programs.
