Adaptive Responses of Morphological Forms of the Pine (<Emphasis Type="Italic">Pinus sylvestris</Emphasis> L.) under Stressful Conditions of the Northern Taiga (in the Northern Dvina Basin)

The variability of physiological and biochemical indicators and radial growth of different forms of Pinus sylvestris L. f. (var.) sulfuranthera Kozubow and f. (var.) erythranthera Sanio under flooding conditions has been studied. It is shown that the dynamics of photosynthetic pigments (chlorophylls and carotenoids), proline, proteins, ascorbic acid, peroxidase activity, and the light-harvesting complex in the pine needles depend on meteorologic factors and the phenophase. Forms with different colors of anthers differ in seasonal dynamics of the content of stressful metabolites and age variability of the radial growth of wood. Our results indicate that different forms of Pinus sylvestris L. have nuances in adaptation to stress conditions.

A detailed characteristic of the beetle fauna associated with Fomitopsis pinicola (Sw.: Fr.) Karst. (Basidiomycetes, Aphyllophorales) in the Urals and Transurals is given. Thirty species from 14 families have been revealed, the commonest species including Eridaulus jacquemarti Mel., Ennearthron laricinum (Mel.) (Ciidae), Dorcatoma dresdensis Hbst., D. lomnickii Rtt., D. punctulata Muls. (Anobiidae), Diaperis boleti (L.) (Tenebrionidae), Scaphisoma agaricinum (L.), S. inopinatum Löbl, S. subalpinum Rtt. (Scaphidiidae), Ostoma ferruginea (L.), and Peltis grossa (L.) (Peltidae). The main trends in the ecological and trophic specialization of mycetophilous beetles are discussed, and some regularities of formation of mycetophilous complexes at different stages of the trees fungi fruit body development are revealed.     

A review of sciarids of the genus <Emphasis Type="Italic">Leptosciarella</Emphasis> Tuomikoski 1960 (Diptera,Sciaridae) in the Altai fauna,with description of three new species

The taxonomy of the genus Leptosciarella Tuomikoski, 1960 in the Altai Area within Altai Territory and the Altai Republic was studied. Eleven species were recognized, including three new species which are described and illustrated here: Leptosciarella (L.) ulagana Komarova sp. n., L. (L.) angustistylus Komarova sp. n., L. (L.) senex Komarova sp. n. Additionally, L. (L.) fuscipalpa (Mohrig et Mamaev 1979) and L. (L.) truncata (Tuomikoski 1960) are recorded from Altai for the first time. A key to the Altai species is provided.     

Dehydrin stress proteins in <Emphasis Type="Italic">Pinus sylvestris</Emphasis> L. needles under conditions of extreme climate of Yakutia

This is the first study to investigate stress proteins dehydrins with the use of specific antibodies in the Scots pine (Pinus sylvestris L.) needles and their changes in the annual cycle under extreme climate of Yakutia. No pronounced polymorphism of major dehydrins (14–15 and 66 kDa) has been found during the winter dormancy period of P. sylvestris. A clear correlation between the seasonal variations in dehydrins and changes in the water content in needles was revealed. Consistently high levels of dehydrins was retained throughout the period of low negative temperatures. It is assumed that dehydrins can participate in the formation of P. sylvestris L. resistance to the permafrost conditions.     

The Larvae of Three Species of Jewel Beetles of the Subgenus <Emphasis Type="Italic">Chrysoblemma</Emphasis> Jakovlev, 1889, Genus <Emphasis Type="Italic">Sphenoptera</Emphasis> Dejean, 1833 (Coleoptera,Buprestidae), from Turkmenistan

The larvae of three species of jewel beetles of the subgenus Chrysoblemma Jakovlev of the genus Sphenoptera Dejean are described: Sphenoptera (Ch.) tamarisci beckeri Dohrn reared from Horaninovia ulicina Fisch. et Mey., Atriplex tatarica L. and Salsola arbuscula Pall.; Sphenoptera (Ch.) tomentosa Jakovlev from Salsola arbuscula; Sphenoptera (Ch.) amplicollis Jakovlev from Salsola orientalis S.G. Gmel. and Halothamnus glaucus (Bieb.) Botsch. Differential diagnoses to distinguish them from the previously described sphenopterine larvae are given.     

Photosynthetic pigments of phytoperiphyton in the Sylva River (Middle Ural)

The pigment composition of phytoperiphyton algocenoses on stones and macrophytes (Potamogeton lucens L., P. perfoliatus L., P. gramineus L., P. pectinatus L., Mirophyllum spicatum, Petasites hybridus (L.) Gaertn., Mey. et Sxherb, Nuphar lutea L., and Alisma plantago-aquatica L.) in the submontane Sylva River (Middle Ural) is considered based on the surveys of 2000–2012. The wide variability in the content of plant pigments in phytoperiphyton depends on the season and type of substrate. The maximum values similar for all substrates are observed at the end of summer. The concentrations of Chl a increase during warm low-water years. Chlorophyll a prevails among green pigments in periphyton; the relative concentration of other pigments is lower. The concentration of plant carotenoids in epiphyton is slightly higher compared to epilithon and is comparable to the Chl a level. The trophic state index of the Sylva River may be determined as mesotrophic or weakly eutrophic when the Chl a concentration in phytoperiphyton is used as a marker.     

Morphology and molecules reveal the alien <Emphasis Type="Italic">Posthodiplostomum centrarchi</Emphasis> Hoffman, 1958 as the third species of <Emphasis Type="Italic">Posthodiplostomum</Emphasis> Dubois, 1936 (Digenea: Diplostomidae) in Europe

Metacercariae of two species of Posthodiplostomum Dubois, 1936 (Digenea: Diplostomidae) were subjected to morphological and molecular studies: P. brevicaudatum (von Nordmann, 1832) from Gasterosteus aculeatus (L.) (Gasterosteiformes: Gasterosteidae), Bulgaria (morphology, cox1 and ITS1-5.8S-ITS2) and Perca fluviatilis L. (Perciformes: Percidae), Czech Republic (morphology, cox1, ITS1-5.8S-ITS2 and 28S); and P. centrarchi Hoffman, 1958 from Lepomis gibbosus (L.) (Perciformes: Centrarchidae), Bulgaria (morphology, cox1 and ITS1-5.8S-ITS2) and Slovakia (cox1 and ITS1-5.8S-ITS2). In addition, cercariae of P. cuticola (von Nordmann, 1832) from Planorbis planorbis (L.) (Mollusca: Planorbidae), Lithuania (morphology and cox1) and metacercariae of Ornithodiplostomum scardinii (Schulman in Dubinin, 1952) from Scardinius erythrophthalmus (L.) (Cypriniformes: Cyprinidae), Czech Republic, were examined (morphology, cox1, ITS1-5.8S-ITS2 and 28S). These represent the first molecular data for species of Posthodiplostomum and Ornithodiplostomum Dubois, 1936 from the Palaearctic. Phylogenetic analyses based on cox1 and ITS1-5.8S-ITS2, using O. scardinii as the outgroup and including the three newly-sequenced Posthodiplostomum spp. from Europe and eight published unidentified (presumably species-level) lineages of Posthodiplostomum from Canada confirmed the distinct status of the three European species (contrary to the generally accepted opinion that only P. brevicaudatum and P. cuticola occur in the Palaearctic). The subspecies Posthodiplostomum minimum centrarchi Hoffmann, 1958, originally described from North America, is elevated to the species level as Posthodiplostomum centrarchi Hoffman, 1958. The undescribed “Posthodiplostomum sp. 3” of Locke et al. (2010) from centrarchid fishes in Canada has identical sequences with the European isolates of P. centrarchi and is recognised as belonging to the same species. The latter parasite, occurring in the alien pumpkinseed sunfish Lepomis gibbosus in Europe, is also supposed to be alien for this continent. It is speculated that it colonised Europe long ago and is currently widespread (recorded in Bulgaria, Slovakia and Spain); based on the cox1 sequence of an adult digenean isolate from the Ebro Delta, Spain, only the grey heron (Ardea cinerea L.) (Ciconiiformes: Ardeidae) is known to be its definitive host in Europe.     

An ethnobotany of the Lukomir Highlanders of Bosnia &amp; 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.

     

Ecological ranges and types of rarity in the Kuznetsk Alatau of some <Emphasis Type="Italic">Saussurea</Emphasis> DC. species

An analysis of indicator values of four Saussurea DC. species, S. baicalensis (Adams) B. L. Rob., S. frolowii Ledeb., S. salicifolia (L.) DC., and S. schanginiana (Wydl.) Fisch. ex Serg., have been carried out by the method of indicator scales of soil moisture and nutrient availability and salinity in more than 1600 relevés. The size of their ecological ranges and the values of their competitiveness in phytocenoses are determined. As a result of a comparison of the locality of local populations within the ecological range and their occurrence, the vulnerability of S. baicalensis, S. frolowii, S. salicifolia, and S. schanginiana in the Kuznetsk Alatau is evaluated. The types of rarity for these species in the Kuznetsk Alatau are determined.     

On the ecology of some species of genus <Emphasis Type="Italic">Stuckenia</Emphasis> (Potamogetonaceae) in lakes of Zabaykalsky krai and the Republic of Buryatia

This paper clarifies the distribution and ecology of representatives of the genus Stuckenia (S. chakassiensis (Kaschina) Klinkova, S. pectinata (L.) Börner, S. macrocarpa (Dobroch.) Tzvelev, and S. vaginata (Turcz.) Holub) in brackish and saline lakes in eastern Russia. It is shown that S. chakassiensis grows in most Transbaikal lakes with a high salinity instead of S. pectinata, as was described earlier. Therefore, the range of this interesting and still insufficiently known taxon significantly extends to the east of Russia. Being very common in the mineralized waters of West Siberia, S. macrocarpa was not observed in Transbaikalia. In soda waters of Transbaikalia, S. chakassiensis forms thickets with a rather high productivity.     

The parasitic wasp <Emphasis Type="Italic">Baryscapus crassicornis</Emphasis> (Erdös) (Hymenoptera,Eulophidae) developing in larvae of the weevil genus <Emphasis Type="Italic">Larinus</Emphasis> germar (Coleoptera,Curculionidae)

Baryscapus crassicornis (Erdös) was reared from the last instar larvae of three species of Curculionidae: Larinus idoneus Gyllenhal, developing in the inflorescences of Jurinea cyanoides (L.), L. turbinatus (Gyllenhal), developing in Cirsium arvense (L.) in Russia (Ul’yanovsk Province), and L. latus (Herbst), developing in Onopordum acanthium L. and O. leptolepis DC. (Asteraceae) in Iran. Data on the parasitoid and its hosts biology, variation of morphological characters, and diagnostic notes are provided. The 3rd instar larva and the pupa of B. crassicornis are described for the first time.     

A review of the <Emphasis Type="Italic">Thinodromus lunatus</Emphasis> species-group (Coleoptera,Staphylinidae)

The Thinodromus lunatus species group is revised. The following new species are described: Thinodromus (s. str.) cattiensis sp. n. from Vietnam, Thinodromus (s. str.) forsteri sp. n. from southern Thailand, Thinodromus (s. str.) himalayensis sp. n. from Nepal and northern India, Thinodromus (s. str.) inconspicuus sp. n. from southern China, Thailand, and Vietnam, and Thinodromus (s. str.) spotus sp. n. from southern China. The following new synonymy is established: Thinodromus (s. str.) deceptor (Sharp, 1889) = Thinodromus (s. str.) gravelyi (Bernhauer, 1926), syn. n.; = Thinodromus (s. str.) reitterianus (Bernhauer, 1938), syn. n. Lectotypes are designated for Trogophloeus lunatus Motschulsky, 1857, Trogophloeus pustulatus Bernhauer, 1904, Trogophloeus socius Bernhauer, 1904, Trogophloeus sumatrensis Bernhauer, 1915, Trogophloeus lewisi Cameron, 1919, Trogophloeus gravelyi Bernhauer, 1926, Trogophloeus reitterianus Bernhauer, 1938, and Trogophloeus unipustulatus Cameron, 1941. A key is presented to all the species of the Thinodromus lunatus group.     

Closure of Stomata in Water-Stressed Pine Needles Results from the Decreased Water Potential of the Mesophyll Apoplast in the Substomatal Cavity

Pine (Pinus sylvestris L.) seedlings grown under controlled conditions were subjected to water deficit (external water potentials ranging from–0.15 to–1.5 MPa) by adding polyethylene glycol 6000 (PEG) to the nutrient solution. Following this treatment, the dry weights of plant shoots and roots, as well as the ratio of variable to maximum chlorophyll fluorescence (F_v/F_m), nonphotochemical quenching (NPQ) of chlorophyll excitations, photosynthetic CO₂/H₂O exchange, dark respiration of needles, and water potential of mesophyll apoplast in the substomatal cavity of pine needles, were measured. The imposed water deficit was followed by the inhibition of seedling growth, suppression of photosynthesis and transpiration, and by the decreased content of photosynthetic pigments. It is shown for the first time that the closure of stomata in the needles of water-stressed pine seedlings falls into the physiological reaction norm and is caused by the reduction of water potential in the mesophyll apoplast of the substomatal cavity.     

New species of the bristletail families Ateluridae and Lepismatidae (Zygentoma) from Abkhazia and Adygea

Four new species of the bristletail families Ateluridae (Atelura abkhazica sp. n. and Nipponatelurina caucasica sp. n.) and Lepismatidae (Lepisma xylophila sp. n. and L. adygei sp. n.) are described. Atelura abkhazica sp. n. differs from the other species of the genus Atelura in a smaller size, smaller number of ovipositor divisions, in the presence of apical sensory cones on the male parameres, which are absent in the other species of the genus, and in a fewer number of lateral pegs on urotergite X. The genus Nipponatelurina comprises two species (N. kurosai Mendes et Machida, 1994 and N. caucasica sp. n.). The distinguishing features of N. caucasica sp. n. include a significant number of short minute thin cilia on the head capsule, a longer ultimate segment of the maxillary palp, and a fewer number of setae at the posterior margin of urosternites IV–VII. Lepisma xylophila sp. n. differs from L. saccharinum and L. chlorosoma in the distribution of epidermic pigment and in the urotergites chaetom. Lepisma adygei sp. n. is most closely related to the synanthropic species L. saccharinum, but differs in the size of the body, color of scales on the upper surface of the body, and in the structure of the labial palps, urotergite X, ovipositor, and parameres.     

On distribution and ecology of some species of cleonines (Coleoptera,Curculionidae): IV. Genus <Emphasis Type="Italic">Lixus</Emphasis> F., subgenus <Emphasis Type="Italic">Eulixus</Emphasis> Reitt.

Data on habitats, food plants of larvae and adults, feeding, mating, oviposition, larval and pupal development, natural enemies, and distribution of seven weevil species (Lixus canescens F.-W., L. iridis Ol., L. myagri Ol., L. punctirostris Boh., L. subtilis Boh., L. incanescens Boh., and L. brevipes Bris.) are given. New host plants of L. canescens and L. iridis are revealed. Gall induction by L. brevipes is reported for the first time. Distribution of all the species in Ukraine and Russia (the latter based on the literature) are given in more detail. Information on the known and potential economic importance of every species is provided.     

Tracking the impact of drought on functionally different woody plants in a Mediterranean scrubland ecosystem

Climate warming is predicted to amplify drought stress. Thus, it is important to understand how coexisting plant species respond to severe droughts. Here we study how seven Mediterranean woody plant species with different evolutionary history and functional characteristics (Pinus halepensis Mill., Juniperus phoenicea L., Pistacia lentiscus L., Rhamnus lycioides L., Rosmarinus officinalis L., Genista scorpius (L.) DC., and Globularia alypum L.) responded to a severe winter drought during 2011–2012 in Spain. The study site is located in the Valcuerna valley, Monegros desert, northeastern Spain. We evaluated how the drought affected the annual growth-ring formation of the species by using dendrochronology and quantified the intensity of drought-induced defoliation and mortality and compared it between species and groups of species with different evolutionary history. Radial growth of all species was strongly reduced by the 2012 drought. The pre-Mediterranean species (P. halepensis, J. phoenicea, P. lentiscus and R. lycioides) reduced growth more than the Mediterranean species (R. officinalis, G. scorpius and G. alypum). Defoliation was significantly higher in pre-Mediterranean than in Mediterranean species. When species were analyzed separately we found that P. halepensis was the species with the highest growth reduction but J. phoenicea was defoliated more severely and showed higher mortality rates as a consequence of drought. In the case of the Mediterranean shrubs, drought-induced mortality was only noticeable in R. officinalis. Drought impacted growth of all species but this did not induce mortality in all of them. Growth reduction was dependent on evolutionary history. However, functional characteristics of the species such as leaf stomatal regulation and root architecture may be more important than evolutionary history on explaining drought-induced mortality. Indeed, species with shallow root systems such as J. phoenicea and R. officinalis were the most adversely affected by the drought.     

In vitro leishmanicidal activity and theoretical insights into biological action of ruthenium(II) organometallic complexes containing anti-inflammatories

Leishmaniasis, a neglected tropical disease caused by protozoans of the genus Leishmania, kills around 20–30 thousand people in Africa, Asia, and Latin America annually and, despite its potential lethality, it can be treated and eventually cured. However, the current treatments are limited owing to severe side effects and resistance development by some Leishmania. These factors make it urgent to develop new leishmanicidal drugs. In the present study, three ruthenium(II) organometallic complexes containing as ligands the commercially available anti-inflammatories diclofenac (dic), ibuprofen (ibu), and naproxen (nap) were synthesized, characterized, and subjected to in vitro leishmanicidal activity. The in vitro cytotoxicity assays against Leishmania (L.) amazonensis and Leishmania (L.) infantum promastigotes have shown that complexes [RuCl(dic)(η⁶-p-cymene)] (1) and [RuCl(nap)(η⁶-p-cymene)] (3) were active against both Leishmania species. Complex [RuCl(ibu)(η⁶-p-cymene)] (2) has exhibited no activity. The IC₅₀ values for the two active complexes were respectively 7.42 and 23.55 μM, for L. (L.) amazonensis, and 8.57 and 42.25 μM, for L. (L.) infantum. Based on the toxicological results and computational analysis, we proposed a correlation between the complexes and their activity. Our results suggest both complexation to ruthenium(II) and ligands structure are key elements to leishmanicidal activity.     

Features of expression of the <Emphasis Type="Italic">PsSst1</Emphasis> and <Emphasis Type="Italic">PsIgn1</Emphasis> genes in nodules of pea (<Emphasis Type="Italic">Pisum sativum</Emphasis> L.) symbiotic mutants

The sequences of the PsSst1 and PsIgn1 genes of pea (Pisum sativum L.) homologous to the symbiotic LjSST1 and LjIGN1 genes of Lotus japonicus (Regel.) K. Larsen are determined. The expression level of PsSst1 and PsIgn1 genes is determined by real-time PCR in nodules of several symbiotic mutants and original lines of pea. Lines with increased (Sprint-2Fix^– (Pssym31)) and decreased (P61 (Pssym25)) expression level of both genes are revealed along with the lines characterized by changes in the expression level of only one of these genes. The revealed features of the PsSst1 and PsIgn1 expression allow us to expand the phenotypic characterization of pea symbiotic mutants. In addition, PsSst1 and PsIgn1 cDNA is sequenced in selected mutant lines, characterized by a decreased expression level of these genes in nodules, but no mutations are found.
