Raster and original working data for the paper Holocene matters: landscape history accounts for current species richness of vascular plants in forests and grasslands of eastern Central Europe
<p>Aim: Current species-richness patterns are sometimes interpreted as a legacy of landscape history, but historical processes shaping the distribution of species during the Holocene are frequently omitted in biodiversity models. Here, we test their importance in modelling current species richness of vascular plants in forest and grassland vegetation.<br> Location: Western Carpathians and adjacent regions.<br> Taxon: Vascular plants.<br> Methods: Numbers of all species and of habitat specialists were extracted from plot records of forest and grassland vegetation. For each plot, environmental and historical data were derived from thematic maps. Historical data related to the persistence of (i) temperate taxa during the Late Glacial and Early Holocene, (ii) open-landscape taxa during the Middle Holocene, and (iii) taiga species during the Late Holocene were based on 112 fossil pollen profiles. Boosted regression trees were used to model spatial patterns in species richness.<br> Results: Historical variables always appeared among the best predictors of current species richness. In light forests, species richness highly mirrored both the Late Glacial (12.5% contribution) and Middle-Holocene (8.6%) landscape history. The latter factor became an important predictor also for species richness of steppe grasslands (8.3%) along with temperature seasonality (11.9%). Species richness of dark coniferous forests was best predicted by the Late-Holocene occurrence of taiga forests (14.8%), which had an even stronger effect on the richness of habitat specialists (20.5%). <br> Main conclusions: Landscape changes since the Last Glacial Maximum are important predictors of current plant species richness. The historical effects were found to be habitat-specific and, because they may interact with recent environmental conditions and anthropogenic pressures, they often show a non-linear relationship with species richness. We provide one possible direction of incorporating past landscape changes into the models of species richness.</p>

Higher vascular plant abundance associated with decreased ecosystem respiration after 20 years of warming in the forest-tundra -ecotone
<p><span>The ongoing climate warming is promoting shrub abundance in high latitudes, but the effect of this phenomenon on ecosystem functioning is expected to depend on whether deciduous or evergreen species increase in response to warming. </span></p> <p><span>To explore effects of long-term warming on shrubs and further on ecosystem functioning, we analyzed vegetation and ecosystem CO<sub>2</sub> exchange after 20 years of warming in the forest-tundra ecotone in sub-arctic Sweden. A previous study conducted nine years earlier had found increased evergreen <em>Empetrum</em> <em>nigrum</em> ssp. <em>hermaphroditum</em> in the forest and increased deciduous <em>Betula</em> <em>nana</em> in the tundra. </span></p> <p><span>Following current understanding, we expected a continued increase in shrub abundance that would be stronger in tundra than in forest. We expected warming to increase ecosystem respiration (</span><span>R<sub>e</sub></span><span>) and gross primary productivity (GPP), with a greater increase in </span><span>R<sub>e </sub>in tundra due to increased deciduous shrub abundance, leading to a less negative net ecosystem exchange (NEE) and reduced ecosystem C sink strength. </span></p> <p><span>As predicted, vascular plant abundances were higher in the warmed plots with a stronger response in tundra than in forest. </span><span>However, whereas <em>B. nana</em> had increased in abundance since the last survey, <em>E. hermaphroditum </em>abundance had declined due to several moth and rodent outbreaks during the past decade. </span><span>I</span><span>n contrast to predictions, </span><span>R<sub>e </sub>was significantly lower in the warmed plots irrespective of habitat, and GPP increased marginally only in the forest. The lower R<sub>e</sub> and a higher GPP under warming in the forest together led to increased net C sink. </span><span>R<sub>e </sub>was negatively associated with the total vascular plant abundance.</span></p> <p><span>Our results highlight the importance of disturbance regimes for vegetation responses to warming. </span><span>Climate warming may promote species with </span><span>both a high capacity to grow under warmer conditions and a resilience towards herbivore outbreaks. Negative correlation between R<sub>e</sub> and total vascular plant abundance further indicates that t</span><span>he </span><span>indirect impacts of increased plants on soil microclimate may become increasingly important for ecosystem CO<sub>2</sub> exchange </span><span>in the long </span><span>run</span><span>, </span><span>which adds to the different mechanisms that link warming and CO<sub>2</sub> fluxes in northern ecosystems.</span></p>
Pattern and driver of the compositional variations in a tropical cloud forest: Comparing vascular epiphytes with terrestrial woody plants
<p>β-diversity patterns (the compositional variations across sites) and their drivers are the major concerns of biodiversity research and conservation practices, whereas such information remains scarce for vascular epiphytes, especially in tropical forest communities. This study aimed to reveal the pattern and driving process of the compositional variations of vascular epiphytes in a tropical cloud forest on Hainan island, southern China, and their differences from those of terrestrial woody plants. To this end, we quantified their between-habitat compositional variations and distinguished the underlying components of β-diversity (nestedness and turnover). We then examined the relative roles of niche-based and neutral processes in driving the compositional variations by using a null model approach. Our results showed that the between-habitat compositional variations were significant for both plant assemblages and stronger in vascular epiphytes than in terrestrial woody plants. The turnover component of β-diversity was significantly stronger in terrestrial woody plants, accounting for 73.16%–80.08% of the variations. By contrast, the nestedness component was significantly stronger in vascular epiphytes and characterized 46.82%–67.5% of the variations. Besides, the compositional variations of both plant assemblages, especially terrestrial woody plants, were generally poorly fitted by the simulated niche-based scenarios but well fitted by the simulated neutral scenarios. Overall, the compositional variations of both plant assemblages were significant and mainly due to dispersal limitation, albeit to varying degrees. Hence, further studies of these plant assemblages at local scales should not be ideologically limited to the niche-based framework. Moreover, the stronger nestedness observed in vascular epiphytes suggests the greater importance of prioritizing conservation efforts in the species-rich habitats for these plants.</p>

Raw data for the manuscript entitled "Forest age and topographic position jointly shape the species richness and composition of vascular plants in karstic habitats"
<p>Doline surveys from the Mecsek Mountains, Hungary. Transects were established with north to south orientation across each doline, traversing their deepest point. Transects began and ended on doline rims, and consisted of 1 m  × 1 m plots spaced at 2 m intervals (94, 89, 90 and 99 plots in the different forest age classes, respectively; 372 plots in total). We recorded the presence/absence data of shrubs and herbs in each plot. Fieldwork was carried out between 2007 and 2019 from June to August, at the peak of the growing season.</p>
