Abstract The relative importance of global versus local environmental factors for growth and thus carbon uptake the bryophyte genus Sphagnum— main peat‐former ecosystem engineer in northern peatlands—remains unclear. We measured length net primary production (NPP) two abundant Sphagnum species across 99 Holarctic peatlands. tested previously proposed abiotic biotic drivers peatland (climate, N deposition, water table depth vascular plant cover) on these responses. Employing structural...
Recent studies show that soil eukaryotic diversity is immense and dominated by micro-organisms. However, it unclear to what extent the processes shape distribution of in plants animals also apply Major diversification events multicellular organisms have often been attributed long-term climatic geological processes, but impact such on protist has received much less attention as their believed be largely cosmopolitan. Here, we quantified phylogeographical patterns Hyalosphenia papilio, a large...
ABSTRACT Motivation Pollinators play a crucial role in maintaining Earth's terrestrial biodiversity. However, rapid human‐induced environmental changes are compromising the long‐term persistence of plant‐pollinator interactions. Unfortunately, we lack robust, generalisable data capturing how communities structured across space and time. Here, present EuPPollNet (European Plant‐Pollinator Networks) database, fully open European‐level database containing harmonised taxonomic on interactions...
The present study is based on a follow-up of survey carried out in 2000, consisting the revisitation ten sites, with scope assessing changes composition and richness epiphytic macrolichens within Cluj-Napoca city over past 24 years. Within this period most polluting factories from outskirts were closed but turn, number registered cars increased almost six-fold. An increasing compositional homogenization by contribution generalist, stress-tolerant species was detected time while total lichen...
Abstract. Rain-fed peatlands are dominated by peat mosses (Sphagnum sp.), which for their growth depend on nutrients, water and CO2 uptake from the atmosphere. As isotopic composition of carbon (12,13C) oxygen (16,18O) these Sphagnum affected environmental conditions, tissue accumulated in constitutes a potential long-term archive that can be used climate reconstruction. However, there is inadequate understanding how isotope values influenced restricts current use as palaeoenvironmental...
This report describes the Romanian Grassland Database (RGD), registered under EU-RO-008 in Global Index of Vegetation-Plot Databases (GIVD).This collaborative initiative aims to collect all available vegetation-plot data (relevés) grasslands and other open habitats from territory Romania provide them for science, nationally internationally, e.g.via European Vegetation Archive (EVA) global database "sPlot".The mainly contains vegetation-plots not only wet, mesic, dry, saline, alpine rocky...
Land abandonment in sub-Mediterranean grasslands causes the spread of tall-grasses, affecting biodiversity and ecosystem functioning. Mowing allows recovery coenological composition after invasion, but mechanisms acting at fine-scale are poorly investigated. Since 2010 Central Apennines, we fenced a grassland invaded by Brachypodium rupestre, divided it into two areas, half each was mowed biyearly remained unmown. In 2017 selected ten 20 × cm experimental units per half-area, collecting data...
The presence data of 153 bryophyte species, recorded on beech (BDW) and spruce (SDW) deadwood in the managed forests within a montane watershed, were analysed by controlling for different plot size, substrate pH elevation. Only three pleurocarpous which probably remnant epiphytes from live wood, showed relative specificity BDW, but none to SDW. few species displaying preference BDW or SDW generally true epixylic, mosses hepatics, respectively. chances occurrence epiphytic (early...
Abstract Here, from macrophylogeographic mtDNA empirical data, we propose a scenario for the evolution and speciation of two important forest trees, European black pine Scotch pine, their multiple subspecies varieties. Molecular clock simulations revealed that INDEL variability in Pinus mitochondrial genome is relatively old, i.e., Pliocene-Miocene epoch, related to historical tectonic continental fluctuations rather than climate change at large geographic scale. For conservation management...
Abstract The paper presents an inventory and distribution of invasive alien species, in “Iron Gates” Natural Park, especially to highlight their origins, the most aggressive impact on conservation status habitats, indirectly economic sociological human communities. This study may have important role improving efficiency measures, offering valuable information authorities involved protected areas administration.
The historical changes in European Black Pine population size across the whole natural distribution Europe and Asia Minor were analyzed facing Plio-Pleistocene climatic fluctuations. Thirteen chloroplast SSRs SNPs markers have been studied under assumptions of "neutral evolution." Populations meta-populations had different histories migration routes, they strongly affected by complex patterns isolation, fragmentation, speciation, expansion (1.88–4.28 Ma), purification selection (2.09–21.41...
Calcareous and rich fens harbour the unique biodiversity of plants invertebrates. They are extremely sensitive to landscape changes because their island nature. In Carpathians, they still well-preserved, but number has substantially decreased. Knowledge about variability classification into vegetation units, a baseline for efficient nature conservancy, is insufficient in Eastern where phytosociology used different methodologies than Western Carpathians. It resulted artificial boundaries...
Abstract In order to develop a proper conservation programme for several endangered, rare or endemic species of Dianhtus from Romania, molecular characterization by simple sequence repeat (SSR) markers has been accomplished. Amplification SSR loci in individuals belonging different populations D. callizonus, glacialis ssp. gelidus, D . henteri, nardiformis and tenuifolius revealed 23 polymorphic alleles. callizonus showed particular sets gelidus , henteri proved share almost the same alleles...
