Abstract Although invasive tree species pose a significant threat to biodiversity, their impact on terricolous bryophytes has been insufficiently recognized. In addition, almost all previous studies focused differences between invaded and uninvaded stands, not accounting for the effect of invader abundance. Here we aimed assess Prunus serotina Robinia pseudoacacia nutrient-poor ( Pinus sylvestris stands) nutrient-rich Quercus spp. sites, along gradient biomass. We assessed cover richness by vegetation surveys in 160 study plots (100 m 2 ) biomass eight 0.264 circular subplots.

Naturalization of European plants on other continents: The role of donor habitats

Proceedings of the National Academy of Sciences, Год журнала: 2017, Номер 114(52), С. 13756 - 13761

Опубликована: Дек. 4, 2017

Significance Understanding which species become successful aliens outside their native range is a fundamental question in ecology, as it informs efforts to mitigate ecological and economic losses from biological invasions. For alien plants of European origin, the association with human-disturbed environments suggested key factor for establishment success following introduction other regions, especially similarly disturbed human-made habitats. By combining comprehensive list habitats composition database plant naturalization records worldwide, we showed that broad habitat together human-induced disturbance experienced native-range can increase species’ chance becoming naturalized parts world.

Invasive tree species decrease ecosystem resilience with negative impacts on natural regeneration. The influence of alien ecosystems is unevenly recognized and does not always account for different habitat specificity. We assessed the three most frequent invasive in European forests: Prunus serotina Ehrh., Quercus rubra L., Robinia pseudoacacia L. regeneration diversity, composition, density. hypothesized that invaded forest types, comparison non-invaded, will differ terms have lower taxonomic, functional, phylogenetic diversity regeneration, densities native species. used a set 189 study plots (200 m2) systematic design, established various types Wielkopolski National Park (West Poland). analyzed type, accounting soil C:N ratio, pH, light availability (woody up to 0.5 m height) found an overlap composition among non-invaded forests low taxonomic functional richness. no other components.

Alpha diversity of vascular plants in European forests

Journal of Biogeography, Год журнала: 2019, Номер 46(9), С. 1919 - 1935

Опубликована: Июнь 7, 2019

Abstract Aim The former continental‐scale studies modelled coarse‐grained plant species‐richness patterns (gamma diversity). Here we aim to refine this information for European forests by (a) modelling the number of vascular species that co‐occur in local communities (alpha diversity) within spatial units 400 m 2 ; and (b) assessing factors likely determining observed alpha diversity. Location Europe roughly 12°W–30°E 35–60°N. Taxon Vascular plants. Methods numbers co‐occurring were counted 73,134 georeferenced vegetation plots. Each plot was classified an expert system into deciduous broadleaf, coniferous or sclerophyllous forest. Random Forest models used map explain diversity each forest type separately using 19 environmental, land‐use historical variables. Results Our explained from 51.0% 70.9% variation alpha‐diversity pattern dominated a marked gradient species‐poor north‐western species‐rich south‐eastern Europe. most prominent richness hotspots identified Calcareous Alps adjacent Dinarides, Carpathian foothills Romania Western Carpathians Slovakia. Energy‐related factors, bedrock types terrain ruggedness as main variables underlying patterns. Alpha increases especially with temperature seasonality broadleaf forests, on limestone areas low annual actual evapotranspiration forests. Main conclusions We provide first predictive maps analyses environmental driving plants across Such is important general understanding biodiversity. This study also demonstrates high potential vegetation‐plot databases sources robust estimation at fine grains large areas.

Abstract Levels of plant invasions in different habitat types were assessed several regional studies, but few them from the Mediterranean. Here we compare levels vascular invasion across habitats and communities Sicily. We used a large dataset species presences/absences vegetation plots to analyze patterns considering biogeography, life form phenology alien plants. Vegetation classified based on EUNIS classification European habitats. The invasiveness each was expressed terms its absolute percentage frequency. Representation forms phenological compared between native species. fidelity individual calculated using phi coefficient. Our analysis shows that annual woody are most represented flora Sicily tend have longer flowering period than investigated differed strongly their level by species, ranging 0 15.6% aliens all recorded. Most colonized very or completely lacked them, except for sandy coasts, naturally-disturbed riverbeds, synanthropic It must be noted, however, number occurring given does not relate severity impact habitat. Some invaded (or single) which attain high cover, transforming whole ecosystem. habitat-based approach proved suitable evaluating specificity frequency at scale, improving capacity risk assessment ecological contexts.
