Cím:Ancient Burial Mounds Provide Safe Havens for Grassland Specialist Plants in Transformed Landscapes- A Trait-Based Analysis / Balázs Deák, Zoltán Rádai, Zoltán Bátori, András Kelemen, Katalin Lukács, Réka Kiss, István Elek Maák, Orsolya Valkó

Megjegyzések:Due to the intensified land use in transformed landscapes, grassland biodiversity is often restricted to habitat fragments inadequate for arable use or for urban development. In continental parts of Eurasia, the ?600,000 ancient burial mounds (called ?kurgans") built by nomadic tribes of the steppes are amongst the most widespread landmarks providing refuge for dry grassland species. In our study by using plant functional groups and functional traits, we aimed at gaining insight into the ecological and evolutionary processes shaping the structure and the composition of assemblages of grassland specialist plant species on kurgans embedded in the agricultural landscapes of East-Hungary. As a comparison, we also studied roadside verges and pristine extensive grasslands in the same region. We found that despite their small size, due to the lack of human disturbances and high microhabitat diversity kurgans can maintain a high species richness and percentage cover of specialists, especially when compared to verges. We revealed that assemblages of specialist plants on kurgans are characterized by traits typical to terrestrial habitat islands such as self-compatibility, large seed mass and tall stature. Kurgans and extensive grasslands were characterized by higher functional diversity (both at the level of single traits and multi-trait based functional dispersion) which is probably due to the higher level of environmental heterogeneity compared to the homogeneous environment in verges.

Cím:Roadsides provide refuge for orchids: characteristic of the surrounding landscape / Fekete Réka, Bódis Judit, Fülöp Bence, Süveges Kristóf, Urgyán Renáta, Malkócs Tamás, Vincze Orsolya, Luís Silva, Molnár V. Attila

Megjegyzések:Seminatural habitats are declining throughout the world; thus, the role of small anthropogenic habitats in the preservation of plants is becoming increasingly appreciated. Here, we surveyed the orchid flora of roadside verges in five Central European countries (Austria, Hungary, Romania, Slovakia, and Slovenia) and tested how the surrounding landscape matrix affects the overall number of species and individuals, and also different functional groups of orchids. We found more than 2,000 individuals of 27 orchid species during our surveys. According to our results, the increasing coverage of agricultural and urban areas negatively affects both the number of orchid species and individuals on roadsides. Our study further suggests that differences in the surrounding habitats affect which species are found on roadsides, since the increasing coverage of grasslands or forested areas around orchid occurrences had a significant positive effect on the number of grassland or forest-dwelling species and individuals, respectively. Most variance in orchid numerosity and diversity was explained by the cover of the suitable habitat types of the respective taxa in the surrounding landscape of the sampling points. This highlights the importance of roadsides acting as refugia for numerous species and valuable plant communities as well as in supporting biodiversity in general.

Cím:Roadside verges and cemeteries : comparative analysis of anthropogenic orchid habitats in the Eastern Mediterranean / Réka Fekete, Viktor Löki, Renáta Urgyán, Kristóf Süveges, Ádám Lovas-Kiss, Orsolya Vincze, Attila Molnár V.

Megjegyzések:Several important habitats have become threatened in the last few centuries in the Mediterranean Basin due to major changes adopted in land?use practices. The consequent loss of natural and seminatural orchid habitats leads to the appreciation of small anthropogenic habitats, such as cemeteries and roadside verges. Colonization of cemeteries and roadside verges by orchids has long been known, but no study to date compared the suitability of these two anthropogenic habitats for orchids. Therefore, in this paper our aim was to survey cemeteries and roadside verges and to compare these two habitats regarding their role in conserving Mediterranean terrestrial orchids. We conducted field surveys in three Mediterranean islands, Cyprus, Crete, and Lesbos, where both cemeteries and roadside verges were sampled on a geographically representative scale. We found a total of almost 7,000 orchid individuals, belonging to 77 species in the two anthropogenic habitat types. Roadside verges hosted significantly more individuals than cemeteries in Crete and Lesbos, and significantly more species across all three islands. Our results suggest that although cemeteries have a great potential conservation value in other parts of the world, intensive maintenance practices that characterized cemeteries in these three islands renders them unable to sustain valuable plant communities. On the other hand, roadside verges play a prominent role in the conservation of Mediterranean orchids in Cyprus and Greece. The pioneer status of roadside verges facilitates their fast colonization, while roads serve as ecological corridors in fragmented landscapes.

Cím:Ecosystem engineering by foxes is mediated by the landscape context : a case study from steppic burial mounds / Godó Laura, Tóthmérész Béla, Valkó Orsolya, Tóth Katalin, Kiss Réka, Radócz Szilvia, Kelemen András, Török Péter, Švamberková Eva, Deák Balázs

Megjegyzések:In intensively used landscapes remnant grassland fragments are often restricted to places unsuitable for agricultural cultivation. Such refuges are the ancient burial mounds called 'kurgans', which are typical landscape elements of the Eurasian steppe and forest steppe zone. Due to their hill-like shape, loose soil structure and undisturbed status kurgans provide proper habitats for burrowing mammals. Accordingly, grassland vegetation on kurgans is often exposed to bioturbation, which can influence the habitat structure and plant species pool. In our study we explored the effect of fox burrows and landscape context on the habitat properties and vegetation composition of small landscape elements, using kurgans as model habitats. We surveyed the vegetation of fox burrows and that of the surrounding grassland on five kurgans situated in cleared landscapes surrounded by arable lands, and five kurgans in complex landscapes surrounded by grazed grasslands. We recorded the percentage cover of vascular plants, the amount of litter and soil moisture content in twelve 0.5m?0.5m plots per kurgan, in a total of 120 plots. We found that foxes considerably transformed habitat conditions and created microhabitats by changing the soil nutrient availability and reducing total vegetation cover and litter. Several grassland specialist species, mostly grasses (Agropyron cristatum, Elymus hispidus and Stipa capillata) established in the newly created microhabitats, although the cover of noxious species was also considerable. We found that landscape context influenced the sort of species which could establish on kurgans by affecting the available species pool and soil moisture. Our results revealed that foxes act as ecosystem engineers on kurgans by transforming abiotic and biotic conditions by burrowing. Their engineering activity maintains disturbance-dependent components of dry grasslands and increases local environmental heterogeneity.

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:Complex mitogenomic rearrangements within the Pectinidae (Mollusca: Bivalvia) / Malkócs, Tamás; Viricel, Amélia; Becquet, Vanessa; Evin, Louise; Dubillot, Emmanuel; Pante, Eric
Dátum:2022
ISSN:2730-7182
Megjegyzések:Background: Scallops (Bivalvia: Pectinidae) present extraordinary variance in both mitochondrial genome size, structure and content, even when compared to the extreme diversity documented within Mollusca and Bivalvia. In pectinids, mitogenome rearrangements involve protein coding and rRNA genes along with tRNAs, and different genome organization patterns can be observed even at the level of Tribes. Existing pectinid phylogenies fail to resolve some relationships in the family, Chlamydinae being an especially problematic group. Results: In our study, we sequenced, annotated and characterized the mitochondrial genome of a member of Chlamydinae, Mimachlamys varia?a species of commercial interest and an effective bioindicator?revealing yet another novel gene arrangement in the Pectinidae. The phylogeny based on all mitochondrial protein coding and rRNA genes suggests the paraphyly of the Mimachlamys genus, further commending the taxonomic revision of the classification within the Chlamydinae subfamily. At the scale of the Pectinidae, we found that 15 sequence blocks are involved in mitogenome rearrangements, which behave as separate units. Conclusions: Our study reveals incongruities between phylogenies based on mitochondrial protein-coding versus rRNA genes within the Pectinidae, suggesting that locus sampling affects phylogenetic inference at the scale of the family. We also conclude that the available taxon sampling does not allow for understanding of the mechanisms responsible for the high variability of mitogenome architecture observed in the Pectinidae, and that unraveling these processes will require denser taxon sampling.

Cím:Quintuple parasitism of a great reed warbler nest by common cuckoos / Marton Attila
Dátum:2021
ISSN:2045-7758
Megjegyzések:Multiple parasitism in obligate avian brood parasites occurs when several brood parasitic females lay their eggs in the nest of the same host. While multiple parasitism is common in the highly social, nonevicting cowbird species (Molothrus sp.), in which multiple parasitic nestlings can be raised simultaneously by the same hosts, it is less common in the case of cuckoo species (Cuculus sp.). The first cuckoo nestling to hatch from the egg evicts all nestmates; therefore, it is costly for cuckoo females to lay eggs in already parasitized nests. However, this can occur in sites with very high parasitism rates, and it can even increase the breeding success of the brood parasites, as the presence of multiple parasitic eggs in the nest of the host decreases rejection rates. Here, we present a case of a quintuple brood parasitism of a great reed warbler (Acrocephalus arundinaceus) nest, an extreme form of multiple brood parasitism.

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.

Cím:Plant traits associated with seed dispersal by ducks and geese in urban and natural habitats / Pál Tóth, Andy J. Green, David M. Wilkinson, Kane Brides, Ádám Lovas-Kiss
Dátum:2023
ISSN:2045-7758
Megjegyzések:Ducks and geese are little studied dispersal vectors for plants lacking a fleshy fruit, and our understanding of the traits associated with these plants is limited. We analyzed 507 faecal samples of mallard (Anas platyrhynchos) and Canada goose (Branta canadensis) from 18 natural and urban wetlands in England, where they are the dominant resident waterfowl. We recovered 930 plant diaspores from 39 taxa representing 18 families, including 28 terrestrial and five aquatic species and four aliens. Mallards had more seeds and seed species per sample than geese, more seeds from barochory and hydrochory syndromes, and seeds that on average were larger and from plants with greater moisture requirements (i.e., more aquatic). Mallards dispersed more plant species than geese in natural habitats. Plant communities and traits dispersed were different between urban (e.g., more achenes) and natural (e.g., more capsules) habitats. Waterfowl can readily spread alien species from urban into natural environments but also allow native terrestrial and aquatic plants to disperse in response to climate heating or other global change. Throughout the temperate regions of the Northern Hemisphere, the mallard is accompanied by a goose (either the Canada goose or the greylag goose) as the most abundant waterfowl in urbanized areas. This combination provides a previously overlooked seed dispersal service for plants with diverse traits.

Megjegyzések:Most organisms have to cope with unpredictable environmental challenges such as fluctuations in nutritional resources. Insulin-like growth factor-1 (IGF-1) is an evolutionarily conserved hormone that is highly sensitive to the individual nutritional status and regulates major life-history traits including lifespan and reproduction across vertebrates. We investigated the role of IGF-1 during periods of food shortages by altering between two feeding regimes (110 and 70% of daily food intake) after a period of ad libitum feeding in captive bearded reedlings (Panurus biarmicus). Each dietary treatment was repeated twice. Birds lost mass under food restriction, but the magnitude of mass change depended on the preceding dietary conditions. Moreover, bearded reedlings showed large, repeatable individual differences in their IGF-1 reaction norms with some individuals increasing IGF-1 levels in response to a restricted diet, whereas others showed no responses or decreased IGF-1 levels. This variation was explained by differences in average body mass: heavier individuals had higher IGF-1 levels during the control treatment and were more likely to decrease IGF-1 levels in response to the dietary restriction than did lighter ones. This result uncovers an individual by environment interaction (I x E) and may have important implications for the evolution of IGF-1 related hormonal phenotypes in this species.
