Abstract Aim Revisits of non‐permanent, relocatable plots first surveyed several decades ago offer a direct way to observe vegetation change and form unique increasingly used source information for global research. Despite the important insights that can be obtained from resurveying these quasi‐permanent plots, their use is prone both observer relocation errors. Studying combined effects error types since they will play out together in practice it yet unknown what extent observed changes are...
Patterns of ploidy variation among and within populations can provide valuable insights into the evolutionary mechanisms shaping dynamics plant systems showing diversity. Whereas data on majority ploidies are, by definition, often sufficiently extensive, much less is known about incidence role minority cytotypes.
The patterns of inbreeding coefficients (FIS) and fine spatial genetic structure (FSGS) were evaluated regarding the mating system depression food-deceptive orchids, Dactylorhiza majalis, incarnata var. incarnata, fuchsii, from NE Poland. We used 455 individuals, representing nine populations three taxa AFLPs, to estimate percent polymorphic loci Nei's gene diversity, which are calculated using Bayesian method; FIS; FST; FSGS with pairwise kinship coefficient (Fij); AMOVA in populations....
1. Cities are growing ecosystems in the modern world. Due to their heterogeneity, urban areas have multifaceted influences on organisms, including bees. However, many specific city greenspace designs and management implementations, our understanding of functionality remains limited. This is also true for flower meadows (UFMs). 2. We extensively examined UFMs three large cities answer following question: what features surroundings (urban matrix) most important supporting bees cities? 3. Our...
Understanding the complexity of flower scent—a crucial attractant for pollinators and a key factor in ensuring plant reproduction—is an essential ecological task highly endangered orchids. To address this issue, we studied volatiles profile Neottia ovata, nectar-rewarding orchid known its generalist pollination strategy. We then compared chemical composition N. ovata floral scent with data other species to place our findings context general volatile attractants emitted by or food-deceptive...
A large suite of floral signals, and environmental biotic characteristics influence the behavior pollinators, affecting female success food-deceptive orchids. In this study, we examined many factors shaping reproductive output three orchid taxa:
Abstract We carried out translocations of three rare plants that inhabit mineral islands in the marshy Biebrza Valley order to create alternative populations and facilitate connectivity between existing subpopulations. The species chosen were Iris aphylla two orchids: Cypripedium calceolus Cephalanthera rubra . Thirty soil monoliths with vegetative orchid or parts I. rhizomes dug transplanted different sites on new (half 2012 half 2013). Prior translocation, we measured moisture pH took...
The deception strategies of orchids remain poorly understood, especially in regard to the chemical compounds emitted from their flowers and interaction with various taxonomic groups pollinators. We investigated phylogenetic relationships compared variation floral between food-deceptive Dactylorhiza taxa (D. incarnata var. D. ochroleuca, fuchsii majalis) populations north-eastern Poland. propose a model evolution based on signals this genus. A Bayesian approach polymorphic plastid DNA (trnL,...
Plant-pollinator interactions significantly influence reproductive success (RS) and drive the evolution of pollination syndromes. In context RS, mainly role flower morphology is touched. The importance nectar properties less studied, despite its significance in effectiveness. Therefore, aim this study was to test selection on chemistry generalistic orchid Neottia ovata. 2019–2020, we measured three floral displays six traits, pollinaria removal (PR), female (FRS), determined soil properties....
Introduction Inbreeding depression (ID) in food-deceptive plants have been reported previously, however, it has not often proven that selfed seeds germinate better than outbred ones or selfing affects ID. To resolved these issues, related Dactylorhiza majalis , D. incarnata var. and fuchsii orchids were investigated. Methods Hand pollination treatments control conducted. Fruit set, number of per fruit, seed length, well-developed proportion vitro asymbiotic germination seeds, analyzed...
Abstract Pollinator foraging behavior plays a key role in breeding and therefore affects the evolution of orchid reproductive strategy. Food-deceptive orchids usually implement generalized plant pollination strategy relatively diverse group pollinators visit them. Dactylorhiza majalis is food-deceptive, early-flowering that relies on insect-mediated pollination. This study’s objectives were to identify D. ’ flower visitors their behaviors inflorescences. We also assessed bending movement...
The deficiency of pollinators is indicated as the main factor limiting fruit set in orchids. Nectariferous species are more successful setting fruits than nectarless species. In present study, we tested whether pollinator limitation lowers reproductive success populations <em>Cypripedium calceolus</em> on environmental islands Biebrza National Park, NE Poland. Moreover, analyzed how population size and structure affect pollination success. Our observations results experiments...
<p>In an age of changes in species’ geographical ranges, compounded by climatic and anthropogenic impacts, it become important to know which processes factors influence plant populations their persistence the long term.</p><p>Here we investigated dynamic fitness components twelve <em>Malaxis monophyllos</em> (L.) Sw., situated different (regions) ecological (type habitat) units. Although <em>M. is a rare species, characterized highly fragmented,...
We investigated the phylogeographical structure of boreal-montane orchid Malaxis monophyllos in its Eurasian geographical range. analysed four sequences plastid DNA (trnL, trnL–trnF, rps16 and accD-psaI), resulting 19 haplotypes revealing a high level intraspecific diversity (HD = 0.702 π 0.196 × 10−2), but showing lack structure. This pattern might be caused by multiple phenomena processes, e.g. broad-fronted recolonization with accompanying multi-directional gene flow between populations...
Abstract In the presented study, male and female reproductive success was analyzed in relation to population size, floral display pollinators’ availability natural anthropogenic populations of orchid Malaxis monophyllos (L.) Sw. Our results indicated significant differences between all investigated parameters display, including heights number flowers per inflorescence, as well flowering individuals their spatial structure. Additionally, differed both (pollinia removal) (fruit set) success,...
Many orchid species have evolved complex floral signals to ensure pollination efficiency. Here, the authors combined analyses of anatomical flower structure with volatile composition and flower-visiting insects' behaviour, as well characterised features that can attract pollinators inconspicuous Malaxis monophyllos. During field observations, found only small Diptera (e.g., mosquitos, drosophilids, fungus gnats) visit are interested in flowers M. monophyllos, which was reflected combine...
<em>Polemonium caeruleum</em> (Polemoniaceae) represents a very interesting system of compatibility transition. Studies its biological and ecological properties in the context breeding various populations may help to understand evolutionary mechanism this process. We investigated some aspects system, diversity foraging behavior visitors, relationship between population fruit set three from NE Poland. found distinct systems two studied showed that if is self-compatible (SC),...
Malaxis monophyllos is a rare orchid with fragmented boreal-montane distribution in Europe where it associated both natural swampy and anthropogenic habitats. We employed extensive sampling of M. populations from different habitat types, over its whole European geographic range, to examine genetic diversity patterns phylogeographic structure using amplified fragment length polymorphisms (AFLPs). Our results revealed the relatively low monophyllos, effect small population sizes inbreeding as...
A vast majority of angiosperms are pollinated by animals, and a decline in the number diversity insects often affects plant reproduction through pollen limitation. This phenomenon may be particularly severe rare species, whose populations shrinking. Here, we examined variability factors shaping reproductive success limitation red-listed Polemonium caeruleum L. During 5-year study several P. (7-15, depending on year), assessed degree based differences seed set between open-pollinated...
