AbstractAlthough the geographical location and botanical history of Turkey make the country a perfect place for a potentially rich diversity of eriophyoid mites, little is known about the Turkish eriophyoid fauna. The current paper is a brief review of the existing records of eriophyoid mites found so far in Turkey, with additional information on 6 grass-associated eriophyoid species recorded recently. The 134 eriophyoid species collected in Turkey come from only ca. 1.2% of all Turkish plant species. The role of collecting ecological and molecular data and studying economically significant eriophyoid mites species in this area is particularly stressed.

In recent years, the accumulated molecular data of Turnip mosaic virus (TuMV) isolates from various hosts originating from different parts of the world considerably helped to understand the genetic complexity and evolutionary history of the virus. In this work, four complete TuMV genomes (HC9, PK1, MS04, MS15) were characterised from naturally infected cultivated and wild-growing Papaver spp., hosts from which only very scarce data were available previously. Phylogenetic analyses showed the affiliation of Slovak Papaver isolates to the world-B and basal-B groups. The PK1 isolate showed a novel intra-lineage recombination pattern, further confirming the important role of recombination in the shaping of TuMV genetic diversity. Biological assays indicated that the intensity of symptoms in experimentally inoculated oilseed poppy are correlated to TuMV accumulation level in leaves. This is the first report of TuMV in poppy plants in Slovakia.

AbstractMyxomycetes constitute a group within the Amoebozoa well known for their motile plasmodia and morphologically complex fruiting bodies. One obstacle hindering studies of myxomycete evolution is that their fossils are exceedingly rare, so evolutionary analyses of this supposedly ancient lineage of amoebozoans are restricted to extant taxa. Molecular data have significantly advanced myxomycete systematics, but the evolutionary history of individual lineages and their ecological adaptations remain unknown. Here, we report exquisitely preserved myxomycete sporocarps in amber from Myanmar, ca. 100 million years old, one of the few fossil myxomycetes, and the only definitive Mesozoic one. Six densely-arranged stalked sporocarps were engulfed in tree resin while young, with almost the entire spore mass still inside the sporotheca. All morphological features are indistinguishable from those of the modern, cosmopolitan genus Stemonitis, demonstrating that sporocarp morphology has been static since at least the mid-Cretaceous. The ability of myxomycetes to develop into dormant stages, which can last years, may account for the phenotypic stasis between living Stemonitis species and this fossil one, similar to the situation found in other organisms that have cryptobiosis. We also interpret Stemonitis morphological stasis as evidence of strong environmental selection favouring the maintenance of adaptations that promote wind dispersal.

BackgroundOne hundred years ago psychiatrists thought that ear disease could cause insanity by irritation of the brain. Current understanding of the role of the temporal lobes in schizophrenia and their proximity to the middle ear supports this hypothesis.AimsTo establish the rate of middle-ear disease pre-dating the onset of schizophrenia.MethodEighty-four patients with schizophrenia were each matched to four non-psychiatric controls by age, gender and season of birth. History of ear disease was obtained from general practice records. Additional information on symptoms was collected for participants in the case group, who also had audiometry.ResultsThe odds ratio of recorded middle-ear disease pre-dating schizophrenia was 3.68 (95% CI 1.86–7.28). This excess was particularly marked on the left (OR=4.15, 95% CI 2.08–8.29). Auditory hallucinations were associated with middle-ear disease but not with hearing loss.ConclusionsThere is an association between middle-ear disease and schizophrenia which may have aetiological significance.

The identity of the highland vegetation of the eastern part of the ridge East Sayan is due to the history of the formation of flora and vegetation in the late Pleistocene, as well as to the features of underlying rocks, mainly represented by limestones. As a result, endemic plant species and communities formed on these ancient alignment surfaces. One of these species is Festuca komarovii Krivot. (Komarov fescue). The relictness of Festuca komarovii is confirmed by the systematic position of the species in the generic complex; it belongs to the distinctive section Leocopoa (Griseb.) Krivot. The section combines only three species – Festuca sibirica, F. hubsugulica, F. komarovii, of which the last two are endemic of the Hangai-Sayan center. The Komarov fescue in the modern vegetation of the East Sayan shows itself as a coenogen and indicator of paleocryogenic landscapes. The research results showed a high coenotic role of this fescue in the vegetation of the studied territory, in particular the syntaxa of the cryophyte-steppe florocenotype (unions Kobresion myosuroidis Mirkin et al. 1983 em. Hilbig 2000 and Potentillo niveae–Caricion pediformisТеlyatnikov 2011). We also described the new association Ptilagrosto mongholicae–Festucetum komarovii Namzalov ass. hoc loco, floristically and coenotically related to the associations of the union Dryadion oxyodontae Zhitlukhina et Onishchenko ex Chytrý et al. 1993, which belongs to the class Carici rupestris–Kobresietea bellardii Ohba 1974. However, one important feature should be noted that the Komarov fescue in communities of associations of tundra and subalpine forest vegetation is noted in a small abundance as an accompanying species. To some extent, this confirms the initial coenogenetic proximity of Festuca komarovii to grass ecosystems – cryophytic stepoids of the periglacial Pleistocene complex.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Background: Relatively little is known about the role of protective factors in an Arab population in the presence of suicidal risk factors. Aims: To examine the role of protective factors in a subsample of in large Arab Kindred participants in the presence of suicidal risk factors. Methods: We assessed protective and risk factors in a sample of 64 participants (16 suicidal and 48 nonsuicidal) between 15 and 55 years of age, using a comprehensive structured psychiatric interview, the Composite International Diagnostic Interview (CIDI), self-reported depression, anxiety, hopelessness, impulsivity, hostility, and suicidal behavior in first-degree and second-relatives. We also used the Religiosity Questionnaire and suicide attitude (SUIATT) and multidimensional perceived support scale. Results: Suicidal as opposed to nonsuicidal participants were more likely to have a lifetime history of major depressive disorder (MDD) (68.8% vs. 22.9% χ2 = 11.17, p = .001), an anxiety disorder (87.5% vs. 22.9, χ2 = 21.02, p < .001), or posttraumatic stress disorder (PTSD) (25% vs. 0.0%, Fisher’s, p = .003). Individuals who are otherwise at high risk for suicidality have a much lower risk when they experience higher perceived social support (3.31 ± 1.36 vs. 4.96 ± 1.40, t = 4.10, df = 62, p < .001), and they have the view that suicide is somehow unacceptable (1.83 ± .10 vs. 1.89 ± .07, t = 2.76, df = 60, p = .008). Conclusions: Taken together with other studies, these data suggest that the augmentation of protective factors could play a very important role in the prevention of incidental and recurrent suicidal behavior in Arab populations, where suicidal behavior in increasing rapidly.
