Vegetation classification of acidophilous oak forests in Slovakia

Michal Slezák, Milan Valachovič, Drahoš Blanár, František Máliš, Dusan Senko & Hubert Žarnovičan
Acidophilous oak forests are species-poor forest plant communities usually growing on mineral-poor geological and soil substrates. We compiled a large data set of 263 phytosociological relevés assigned to the Quercion roboris alliance in Slovakia to produce the first syntaxonomical revision at national level. Modified Twinspan algorithm was applied for numerical classification and identifica-tion of basic vegetation units. To find main environmental gradients governing species composition, unconstrained ordination method (Detrended Correspondence analysis; DCA) was used. Floristic...

Data from: The effects of rainforest fragment area on the strength of plant-pathogen interactions

Ashwin Viswanathan, Jaboury Ghazoul, Ganesh Honwad, N. Arun Kumar & Robert Bagchi
Pathogenic interactions between fungi and plants facilitate plant species coexistence and tropical rainforest diversity. Such interactions, however, may be affected by forest fragmentation as fungi are susceptible to anthropogenic disturbance. To examine how fragmentation affects fungus-induced seed and seedling mortality, we sowed seeds of six plant species in soils collected from 21 forest fragments. We compared seedling establishment in unmanipulated soils to soils treated with fungicides. Fungicides increased germination of Toona ciliata seeds and decreased...

Taxon pulse dynamics, episodic dispersal, and host colonization across Beringia drive diversification of a holarctic tapeworm assemblage

Genevieve Haas, Eric Hoberg, Joseph Cook, Heikki Henttonen, Arseny Makarikov, Sarah Gallagher, Nikolai Dokuchaev & Kurt Galbreath
Aim: We test the predictions of the Stockholm Paradigm, a synthesis of eco-evolutionary theory explaining the nature of faunal assembly, host range and parasite diversification. Faunal diversification and assembly, manifested in patterns of host colonization, co-adaptation and parasite speciation, is predicted to emerge as a consequence of alternating episodes of ecological disruption and stability. Specifically, for a diverse cestode genus (Arostrilepis), we evaluate the number and direction of Pleistocene dispersal events across Beringia, the number...

Common-garden experiment reveals clinal trends of bud phenology in black spruce populations from a latitudinal gradient in the boreal forest

Xiali Guo, Marcin Klisz, Radosław Puchałka, Roberto Silvestro, Patrick Faubert, Evelyn Belien, Sergio Rossi & Jianguo Huang
Climate warming is modifying the movement of air masses over Northern latitudes, producing warming and cooling events across the boreal regions. These new conditions changes may mismatch plant phenology from weather conditions, and affect the growing period of trees. Understanding the processes of local adaptation in bud phenology can help to predict the response of plants to these rapid and unexpected environmental changes. Our study monitored bud burst and bud set weekly during four growing...

Data from: Lowest drought sensitivity and decreasing growth synchrony towards the dry distribution margin of European beech

Lena Muffler, Robert Weigel, Andrew J. Hacket-Pain, Marcin Klisz, Ernst Van Der Maaten, Martin Wilmking, Juergen Kreyling & Marieke Van Der Maaten-Theunissen
Aim: Climate limits the potential distribution ranges of species. Establishment and growth of individuals at range margins is assumed to be more limited by extreme events such as drought or frost events than in the centre of their range. We explore whether the growth of beech is more sensitive to drought towards the dry distribution margin and more sensitive to frost towards the cold distribution margin. Furthermore, we aim to gain insight into the adaptive...

Plant herbivore interactions: Combined effect of ground water level, root vole grazing and sedge silicification

Zbigniew Borowski, Karol Zub, Marcin Sulwiński, Małgorzata Suska-Malawska & Marek Konarzewski
1. Accumulation of silica (Si) by plants can driven by (1) herbivore pressure (and therefore, plant-herbivore interactions) (2) geo-hydrological cycles or (3) a combination of (1) and (2), with (1-3) possibly affecting Si concentration with a 1-year delay. 2. To identify the relative significance of (1-3) we analysed the concentration of Si in fibrous tussock sedge (Carex appropinquata), the population density of the root vole (Microtus oeconomus) and the ground water level, over 11 years....
