Abstract Wild pollinators are crucial for ecosystem functioning and human food production often rely on floral resources provided by different (semi‐) natural ecosystems survival. Yet, the role of European forests, especially forest herb layer, as a potential provider has scarcely been quantified. In this study, we measured nectar (PNP) layer using resurvey data across 3326 plots in temperate forests Europe, with an average time interval 41 years between both surveys order to assess (i) importance providing wild pollinators, (ii) intra‐annual variation PNP, (iii) overall change PNP survey periods (iv) periods. The estimates availability based relative cover plant species layer. Although overestimates actual production, differences amongst provide valid informative way analyse space. Our results show that large pollinator communities, which is greatest spring, almost 16 g sugar/m 2 /year. However, drastically declined (mean plot‐level decline >24%). Change light availability, associated shifts canopy structure composition, key driver temporal changes. Synthesis . study shows if management activities carefully planned sustain nectar‐producing layers whole can play roles sustaining populations.

Understorey vegetation comprises a major portion of plant diversity and contributes greatly to nutrient cycling energy flow. This review examines the mechanisms involved in response understorey stand development overstorey canopy following disturbances. The overall abundance is enhanced with availability heterogeneity light, soil nutrients, moisture, substrates. Vascular plants are positively impacted by light whereas non-vascular more strongly influenced colonization time, substrates, decreased higher proportion broadleaf overstorey. resources prominent driver toward vegetation, from initiation stem exclusion stage under single-species dominated However, resource dominates at later stages succession mixed Climate site conditions modify layer, but extent their influences requires investigation. Forest management practices (clearcutting partial harvesting) tend increase heterogeneity, which facilitates vascular plants; however, these factors reduce occurrence plants.

Abstract Functional traits respond to environmental drivers, hence evaluating trait‐environment relationships across spatial gradients can help understand how multiple drivers influence plant communities. Global‐change such as changes in atmospheric nitrogen deposition occur worldwide, but affect community trait distributions at the local scale, where resources (e.g. light availability) and conditions soil pH) also We investigate responses related resource acquisition (plant height, specific leaf area (SLA), woodiness, mycorrhizal status) regeneration (seed mass, lateral spread) of European temperate deciduous forest understoreys. sampled understorey communities derived global‐change (temperature, precipitation, deposition, past land use), while integrating in‐situ plot measurements on (soil type, Olsen phosphorus (P), Ellenberg moisture, light, litter quality). Among mean annual temperature strongly influenced acquisition. Higher temperatures were associated with taller understoreys producing leaves lower SLA, a higher proportional cover woody obligate (OM) species. Communities plots moisture content had smaller seeds OM Finally, thicker layers hosted larger Our findings suggest potential shifts global warming, highlight importance well for variation.

Summary Forests harbour large spatiotemporal heterogeneity in canopy structure. This variation drives the microclimate and light availability at forest floor. So far, we do not know how sub‐canopy temperature interactively mediate impact of macroclimate warming on understorey communities. We therefore assessed functional response plant communities to addition a full factorial experiment installed temperate deciduous forests across Europe along natural microclimate, gradients. Furthermore, related these responses species’ life‐history syndromes thermal niches. found no significant community treatment. The treatment, however, had stronger communities, mainly due by fast‐colonizing generalists slow‐colonizing specialists. structure strongly mediated also clear traits total cover. effects short‐term experimental were small suggest time‐lag species climate change.

Abstract Forest biodiversity world‐wide is affected by climate change, habitat loss and fragmentation, today 20% of the forest area located within 100 m a edge. Still, edges harbour substantial amount terrestrial biodiversity, especially in understorey. The functional phylogenetic diversity have never been studied simultaneously at continental scale, spite their importance for forests' functioning communities' resilience to future change. We assessed nine metrics taxonomic, understorey plant communities 225 plots spread along edge‐to‐interior gradients deciduous forests across Europe. then derived relative effects edaphic, stand landscape conditions on metrics.

Abstract The vast majority of plant biodiversity associated with temperate forests is harboured by the understorey layer. This layer also plays crucial roles in ecosystem functions such as tree regeneration, nutrient cycling and carbon dynamics. Research using space‐for‐time substitutions resurveys vegetation plots has shown that climate warming, changes forest management resource availability are key determinants change functioning. However, long‐term experiments needed to better unravel their complex interactive effects. Here we study influence nearly a decade experimental light addition fluorescent tubes (as proxy for management‐driven forest‐floor levels) nitrogen input on communities broadleaved forest. Plant shifted towards higher dominance warm‐adapted species, process referred thermophilization. We detected marked community shift all treatments including control plots, reflecting ongoing ambient environmental changes. reordering over time was greater than induced treatments. Thermophilization was, however, greatest when temperature and/or were enhanced. Communities taller response warming increased availability. Synthesis . Our experiment provides important insights into 9 years how canopy density can be adapted limit thermophilization under change.

Chronically elevated ungulate browse pressure in temperate forests worldwide often generates ecological legacies characterized by low plant diversity and contributes to the formation of dense, nearly monodominant, highly recalcitrant layers understory vegetation. Once established, these combined with continued browsing may jointly constrain tree establishment so completely that recovery be unattainable without mitigating pressure, layer, or both. Here, we investigate independent synergistic effects both white-tailed deer (Odocoileus virginianus) hay-scented fern (Dennstaedtia punctilobula) competition on regeneration a 10-year experiment. Specifically, examine how seedling establishment, growth, composition are filtered cover versus removal (gaps), browser presence absence (exclosures), their during 10 years at three hardwood forest sites Pennsylvania, USA.

Notably, observed higher Prunus serotina densities outside exclosures, possibly due greater secondary dispersal.

In undisturbed understories, inertia toward impoverishment was sustained across even where eliminated. Consequently, stand replacing disturbances (whether natural anthropogenic) disrupt reinitiate succession necessary propel out current stasis down pathway leading diversity.
