Megjegyzések:Himantoglossum adriaticum H. Baumann is a long-lived perennial orchid with an adriato-mediterranean distribution. The species-level separation of this species from the more geographically widespread H. hircinum has only recently been confirmed via a combination of molecular and morphometric techniques, which are further developed here. To provide a comprehensive overview of its autecology we integrated previously published information with extensive unpublished data derived mainly from populations in the Keszthely Hills of Hungary. In this paper we assess the distribution, habitat preferences, life history and seed germination (ex situ and in situ) of H. adriaticum, with special emphasis on its reproductive biology.

Cím:The RadOrgMiner pipeline : Automated genotyping of organellar loci from RADseq data / Levente Laczkó, Sándor Jordán, Gábor Sramkó
Dátum:2022
ISSN:2041-210X
Megjegyzések:Different versions of Restriction-site-Associated DNA sequencing (RADseq) have become powerful and popular tools in molecular ecology. Although RADseq datasets are generally regarded as representative of the nuclear genome, reduced representation genomic libraries may also sample the organellar (i.e. the mitochondrial and, in the case of plants, the plastid) DNA. This cytoplasmic genetic variance provides a better understanding of evolutionary history by uncovering past hybridisation and identifying maternal or, rarely, paternal lineage due to rapid lineage sorting. We developed a pipeline that is based on existing bioinformatic tools to automatically mine and genotype organellar loci from RADseq libraries. The efficacy of our pipeline is tested on eight publicly available datasets spanning different phylogenetic levels (i.e. from family-level phylogenies to phylogeography) and RADseq methods (sdRAD, ddRAD, ezRAD, GBS) for genotyping mitochondrial and plastid loci, which were subject to phylogenetic tree reconstruction. In all cases, organellar phylogenies adequately supplemented the original studies by corroborating the large-scale picture based on RADseq or by bringing additional evidence on past or contemporary hybridisation. RADseq methods designed to achieve larger horizontal coverage (i.e. ddRAD, ezRAD) yielded longer organellar alignments, but sdRAD and GBS still provided valuable polymorphic organellar loci at no additional sequencing effort.

Cím:The protected flora of long-established cemeteries in Hungary : Using historical maps in biodiversity conservation / Viktor Löki, András Schmotzer, Attila Takács, Kristóf Süveges, Ádám Lovas-Kiss, Balázs András Lukács, Jácint Tökölyi, Attila Molnár V.

Megjegyzések:The role of anthropogenically influenced habitats in conserving elements of the original wildlife has increased worldwide simultaneously with the disappearance of natural sites. Burial places are able to conserve original elements of the wildlife, and this fact has been known for at least a century. To this day, little is known about long-time changes and the effect of long-time management methods in cemeteries on the flora they harbor. The utility of historical maps in research focused on natural values, as well as in answering questions related to conservation was recently demonstrated, but the use of digitized historical maps in biodiversity research of the Carpathian Basin is very limited. In the present paper, we aimed to predict the conservation potential of long-established and newly established cemeteries of Hungarian settlements with various population sizes based on the digitized maps of the 2nd Military Survey of the Austrian Empire (1819-1869), by categorizing cemeteries into 3 distinct (anthropogenic habitat, cemetery, or natural habitat) types. To build our models, we used records of the protected flora from Hungarian cemeteries, based on data of thematic botanical surveys of 991 cemeteries. Out of the surveyed cemeteries, 553 (56%) harbored protected plants, totaling 306.617 estimated individuals of 92 protected species, belonging to 28 plant families. These species represent 12% of the entire protected flora of Hungary. Hungarian cemeteries play a key role mainly in preserving steppe and dry grassland plant species. Long-established and large cemeteries harbor more protected plant species than small and newly established ones. Human population size of the settlements correlated negatively with the number of protected species and individuals. Moreover, woodland cover and proportion of grassland also significantly positively affected the number of protected plant species in cemeteries.

Cím:Seed mass, hardness, and phylogeny explain the potential for endozoochory by granivorous waterbirds / Lovas-Kiss Ádám, Vincze Orsolya, Kleyheeg Erik, Sramkó Gábor, Laczkó Levente, Fekete Réka, Molnár V. Attila, Green J. Andy
Dátum:2020

Megjegyzések:Field studies have shown that waterbirds, especially members of the Anatidae family, are major vectors of dispersal by endozoochory for a broad range of plants lacking a fleshy fruit, yet whose propagules can survive gut passage. Widely adopted dispersal syndromes ignore this dispersal mechanism, and we currently have little understanding of what traits determine the potential of angiosperms for endozoochory by waterbirds. Results from previous experimental studies have been inconsistent as to how seed traits affect seed survival and retention time in the gut and have failed to control for the influence of plant phylogeny. Using 13 angiosperm species from aquatic and terrestrial habitats representing nine families, we examined the effects of seed size, shape, and hardness on the proportion of seeds surviving gut passage through mallards (Anas platyrhynchos) and their retention time within the gut. We compiled a molecular phylogeny for these species and controlled for the nonindependence of taxa due to common descent in our analyses. Intact seeds from all 13 species were egested, but seed survival was strongly determined by phylogeny and by partial effects of seed mass and hardness (wet load): species with seeds harder than expected from their size, and smaller than expected from their loading, had greater survival. Once phylogeny was controlled for, a positive partial effect of seed roundness on seed survival was also revealed. Species with seeds harder than expected from their size had a longer mean retention time, a result retained after controlling for phylogeny. Our study is the first to demonstrate that seed shape and phylogeny are important predictors of seed survival in the avian gut. Our results demonstrate that the importance of controlling simultaneously for multiple traits and relating single traits (e.g., seed size) alone to seed survival or retention time is not a reliable way to detect important patterns, especially when phylogenetic effects are ignored.

Cím:Seasonal variation of genotypes and reproductive plasticity in a facultative clonal freshwater invertebrate animal (Hydra oligactis) living in a temperate lake / Máté Miklós, Levente Laczkó, Gábor Sramkó, Zoltán Barta, Jácint Tökölyi
Dátum:2022
ISSN:2045-7758
Megjegyzések:Facultative sexual organisms combine sexual and asexual reproduction within a single life cycle, often switching between reproductive modes depending on environmental conditions. These organisms frequently inhabit variable seasonal environments, where favorable periods alternate with unfavorable periods, generating temporally varying selection pressures that strongly influence life history decisions and hence population dynamics. Due to the rapidly accelerating changes in our global environment today, understanding the population dynamics and genetic changes in facultative sexual populations inhabiting seasonal environments is critical to assess and prepare for additional challenges that will affect such ecosystems. In this study, we aimed at obtaining insights into the seasonal population dynamics of the facultative sexual freshwater cnidarian Hydra oligactis through a combination of restriction siteassociated sequencing (RAD-Seq) genotyping and the collection of phenotypic data on the reproductive strategy of field-collected hydra strains in a standard laboratory environment. We reliably detected 42 MlGs from the 121 collected hydra strains. Most of MLGs (N =?35, 83.3%) were detected in only one season. Five MLGs (11.9%) were detected in two seasons, one (2.4%) in three seasons and one (2.4%) in all four seasons. We found no significant genetic change during the 2?years in the study population. Clone lines were detected between seasons and even years, suggesting that clonal lineages can persist for a long time in a natural population. We also found that distinct genotypes differ in sexual reproduction frequency, but these differences did not affect whether genotypes reappeared across samplings. Our study provides key insights into the biology of natural hydra populations, while also contributing to understanding the population biology of facultative sexual species inhabiting freshwater ecosystems.

Cím:Turkish graveyards as refuges for orchids against tuber harvest / Attila Molnár V., Timea Nagy, Viktor Löki, Kristóf Süveges, Attila Takács, Judit Bódis, Jácint Tökölyi
Dátum:2017
ISSN:2045-7758
Megjegyzések:Harvest of orchid tubers for salep production is widespread in Southwestern Asia and the Balkans and constitutes a major conservation risk for wild orchid populations. Synanthropic habitats, such as graveyards are important refuges for orchids and other organisms, and could offer protection from salep harvesting because of their special cultural role. However, little is known about the occurrence and factors influencing harvesting of salep in graveyards. During field surveys of 474 graveyards throughout Turkey, we observed 333 graveyards with orchids, 311 graveyards with tuberous orchids and salep harvest in 14 graveyards. Altogether, 530 individuals of 17 orchid species were collected, representing 9% of the individuals recorded. Harvesting intensity was relatively low and populations were usually not wholly destroyed. However, some species were clearly more affected than others. Salep harvesting risk of orchid species was significantly associated with flowering time, with early-flowering species being more affected. A marginally significant positive relationship with between harvesting risk and species-specific tuber size was also detected. Our data suggest that graveyards might offer some protection against salep harvesting in Turkey, but they also show that some orchid taxa are much more affected than others. Overall, our observations add more weight to the conservation value of these special habitats.
