Using total abundance as a proxy for wild bee species richness: A practical tool for non‐experts Open
As there is growing interest among non‐specialists in participating in pollinator conservation initiatives, developing proxies for wild bee species richness that could be potentially used by non‐experts can aid conservation, decision suppo…

Small net local temporal changes in taxonomic, functional, and phylogenetic biodiversity across European temperate forests Open
Summary We face increasing concerns about how the local diversity of native plant communities responds to various drivers of global change, yet often lack comprehensive studies that integrate several components of diversity and the effects…

Past land-use affects woodland functioning even after complete ecosystem destruction Open
Following World War One (WWI), destroyed woodlands have re-established, while former croplands became afforested. We studied the long-term effects of pre-WWI land-use and WWI-associated disturbances on two functional attributes of these wo…

Joining the locals: Plant invaders shift leaf defenses to match native neighbors Open
Local adaptation is common in invasive plants, but there is no consensus as to whether shifts in functional traits between invader “home” and “away” ranges contribute to their success in competition with native species. Theory based on ene…

Patterns of local plant diversity and community saturation in deciduous forests in Europe Open
Questions How do local forest conditions and characteristics at the forest patch ‐ scale and landscape ‐ scale affect plot‐scale plant diversity in Europe? Do these patterns vary between forest specialists and generalists? Do community sat…

Long-term nitrogen deposition reduces the diversity of nitrogen-fixing plants Open
Biological nitrogen fixation is a fundamental part of ecosystem functioning. Anthropogenic nitrogen deposition and climate change may, however, limit the competitive advantage of nitrogen-fixing plants, leading to reduced relative diversit…

ReSurveyEurope: A database of resurveyed vegetation plots in Europe Open
Aims We introduce ReSurveyEurope — a new data source of resurveyed vegetation plots in Europe, compiled by a collaborative network of vegetation scientists. We describe the scope of this initiative, provide an overview of currently availab…

Unexpected westward range shifts in European forest plants link to nitrogen deposition Open
Climate change is commonly assumed to induce species’ range shifts toward the poles. Yet, other environmental changes may affect the geographical distribution of species in unexpected ways. Here, we quantify multidecadal shifts in the dist…

The affinity of vascular plants and bryophytes to forest microclimate buffering Open
With recent advances in technology and modelling, ecologists are increasingly advised to use microclimate, not the usual coarse scale macroclimate based on weather stations, to better reflect the proximal conditions that species experience…

Plants that have naturalized as aliens abroad have also become more common at home during the Anthropocene Open
Changes in species' native range size and occupancy have been dramatically accelerated by anthropogenic pressures in the last centuries. At the same time humans have introduced thousands of species beyond their historic range limits, and s…

Declining potential nectar production of the herb layer in temperate forests under global change Open
Wild pollinators are crucial for ecosystem functioning and human food production and often rely on floral resources provided by different (semi‐) natural ecosystems for survival. Yet, the role of European forests, and especially the Europe…

Ecological indicator values of understorey plants perform poorly to infer forest microclimate temperature Open
Question Ecological indicator values (EIVs) reflect species‘ optimal conditions on an environmental gradient, such as temperature. Averaged over a community, they are used to quantify thermophilization stemming from climate change, i.e. th…

Limited effects of population age on the genetic structure of spatially isolated forest herb populations in temperate Europe Open
Due to multiple land‐cover changes, forest herb populations residing in forest patches embedded in agricultural landscapes display different ages and, thus, experience differences in genetic exchange, mutation accumulation and genetic drif…

Nutrient‐demanding and thermophilous plants dominate urban forest‐edge vegetation across temperate Europe Open
Questions Forests are highly fragmented across the globe. For urban forests in particular, fragmentation increases the exposure to local warming caused by the urban heat island (UHI) effect. We here aim to quantify edge effects on herbaceo…

Evaluating plant lineage losses and gains in temperate forest understories: a phylogenetic perspective on climate change and nitrogen deposition Open
Summary Global change has accelerated local species extinctions and colonizations, often resulting in losses and gains of evolutionary lineages with unique features. Do these losses and gains occur randomly across the phylogeny? We quantif…

Combining multiple investigative approaches to unravel functional responses to global change in the understorey of temperate forests Open
Plant communities are being exposed to changing environmental conditions all around the globe, leading to alterations in plant diversity, community composition, and ecosystem functioning. For herbaceous understorey communities in temperate…

How generalist insect herbivores respond to alien plants? The case of <i>Aphis fabae</i>–<i>Myzus persicae</i>–<i>Rhododendron ponticum</i> Open
BACKGROUND The enemy release hypothesis (ERH) predicts that alien plant species are unsuitable hosts for native phytophagous insects. However, the biotic resistance hypothesis (BRH) predicts that generalist herbivores may prefer an alien p…

More warm‐adapted species in soil seed banks than in herb layer plant communities across Europe Open
Responses to climate change have often been found to lag behind the rate of warming that has occurred. In addition to dispersal limitation potentially restricting spread at leading range margins, the persistence of species in new and unsui…
