Article
Different European countries have interest in reviving the practice of coppice forest management. Despite in temperate forests the understory represents more than 80% of the plant diversity, it remains overlooked. The lack of knowledge is particularly evident for Italy, where coppice forests represent 42.3% of the forest cover and new demands for c...

Forests are among the most threatened ecosystems at the global scale, and endemic plants are often a vulnerable component of the flora of a given territory. So far, however, European forest endemic taxa have been scarcely investigated, especially those of the understory of the southern regions. Italy has a significant incidence of plant endemism an...

Full-text available
Forest expansion can make an important contribution to the 2015 Paris Agreement, through offsetting Greenhouse gas (GHG) emissions. EU, UK and Scottish forest policy encourages substantial forest expansion. Unfortunately, policy is still inadequately informed by high resolution data, and often assumes a fairly homogenous landscape, uniformly suitab...
Conference Paper
Full-text available
The understory represents a large 90% of biodiversity in temperate forests and is essential in litter decomposition and nutrient cycling. We analysed plant diversity using Shannon's diversity (H') and a special case of H' called compositional diversity (CD) and tested their relationship with different spatial scales, successional stages, and struct...
Conference Paper
Full-text available
Understory plants contribute to >80% of the understory forest diversity and are susceptible to climatic changes. We analysed long-term monitoring and climate data to determine: (a) what are the patterns of functional diversity (FD) through time and across forests, (b) does climate explain these patterns, and (c) does above and belowground FD respon...
Conference Paper
Full-text available
Temperate forest understory poorly contributes to forest biomass but may contain 90% of plant diversity and contributes significantly to ecosystem functions such promoting litter decomposition and nutrient cycling. Furthermore, the understory is extremely sensitive to disturbance, including forest management practices, which may alter resource amou...
Article
Full-text available
Evolutionary history and environmental filtering shape the phylogenetic and functional structure of regional assemblages. However, detecting the footprint of such eco-evolutionary drivers is challenging because these may often counter each other's signature. Here, we examined whether a biogeographic deconstruction approach of phylogenetic (PD) and...
Data
Data from the comspat R package (see the linked manuscript; Tsakalos et al. 2022). The manuscript used three grid data sets (64 × 64 sampling units), including: one simulation (grid_patchy_associated) and two simulation derivatives (grid_random and grid_patchy_no_isc) produced by randomization. We used a spatially explicit individual-based simulat...
Code
The diversity of species combinations observable in sampling units reflects a species' uneven distribution and preference for specific abiotic and biotic conditions – a phenomenon most commonly expressed in terms of ecological assembly rules of plant communities and other sessile organisms (e.g., subtidal algae, invertebrates and coral reefs). We p...

Article
Full-text available
Diversity responses to climatic factors in plant communities are well understood from experiments, but less known in natural conditions due to the rarity of appropriate long-term observational data. In this paper, we use long-term transect data sampled annually in three natural grasslands of different species pools, soils, landscape contexts and la...
Article
Coppice forest management impacts understorey vegetation. This is particularly true for habitat specialists (priority elements in conservation) who prefer closed canopy conditions associated with mature forests. Most trait-based studies of forest understorey focus on interspecific differences, which neglect the role of intraspecific variability. He...
Article
A longstanding research divide exists in plant ecology: either focus on plant clonality with no ambition to address nonclonal plants, or focus on all plants, ignoring that many ecological processes can be affected by the fact that some plants are clonal while others are not. This gap cascades into a lack of distinction and knowledge about the simil...

Environmental circumstances shaping soil microbial communities have been studied extensively, but due to disparate study designs it has been difficult to resolve whether a globally consistent set of predictors exists, or context-dependency prevails. Here, we used a network of 18 grassland sites (11 sampled across regional plant productivity gradien...

This book presents the abstracts of the 13th Clonal plant meeting hosted by the University of Camerino (1st – 3rd September 2021).
Article
How species assemble in a community is still an unresolved question in ecology, especially in forest ecosystems. In temperate forests, the understory layer includes most of the plant diversity and significantly contributes to ecosystem functions. Understory communities are susceptible to changes in environmental conditions linked to forest structur...
Article
Forest understory plants are sensitive to light availability, and different species' groups can respond differently to changing light conditions. A plant trait tightly linked to light capture is specific leaf area (SLA). Studies considering the relative role of within-and among-species SLA variation across different species groups (e.g., specialist...

This paper explores which traits are correlated with fine-scale (0.25 m 2) species persistence patterns in the herb layer of old-growth forests. Four old-growth beech forests representing different climatic contexts (presence or absence of summer drought period) were selected along a north-south gradient in Italy. Eight surveys were conducted in ea...
Article
Dominants are key species that shape ecosystem functioning. Plant dominance is typically assessed on aboveground features. However, belowground, individual species may not scale proportionally in relation to their aboveground dimension. This is especially important in ecosystems where most biomass is allocated belowground, including grassy and shru...

Local biodiversity trends over time are likely to be decoupled from global trends, as local processes may compensate or counteract global change. We analyze 161 long-term biological time series (15–91 years) collected across Europe, using a comprehensive dataset comprising ~6,200 marine, freshwater and terrestrial taxa. We test whether (i) local lo...

This study aims to increase floristic knowledge of Marche by means of a survey in the Montagna di Torricchio State Nature Reserve (central Italy). The Reserve, located in the central Apennines, covers about 3.2 km ² at altitudes ranging from 820 to 1,491 m a.s.l. It has been owned and managed as a strict reserve by the University of Camerino since...
Article
Full-text available
Predicting how biodiversity affects ecosystem functioning requires a multifaceted approach based on the partitioning of diversity into its taxonomic and functional facets and thus redundancy. Here, we investigated how species richness (S), functional diversity (FD) and functional redundancy (FR) are affected by forest structure. Sixty-eight abandon...
Article
Full-text available
Patterns of diversity across spatial scales in forest successions are being overlooked, despite their importance for developing sustainable management practices. Here, we tested the recently proposed U-shaped biodiversity model of forest succession. A chronosequence of 11 stands spanning from 5 to 400 years since the last disturbance was used. Unde...
Article
Full-text available
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research sp...

Full-text available
Plant functional trait data aggregated at the community level (i.e., community weighted mean, CWM) are fundamental to study plant-environment relationships. Here, we provide a large database of CWM values of twelve traits reflecting several plant functions, including leaf, seed, whole-plant, clonal and bud bank traits. The CWMs were calculated in 2...
Article
Species richness is a key variable in measuring diversity of ecological communities. It is crucial to get reliable estimates for the number of plant species in space (mapping) and-even more important in the context of monitoring-over time. Therefore, knowledge on error rates related to recordings of species numbers should be considered in such inve...

Article
QUESTION: In functional biogeography studies, generalizable patterns in the relationship between plant traits and the environment have yet to emerge. Local drivers (i.e., soil, land use, vegetation structure) can increase our understanding of trait‐environment relationship. What is the role of climate and local drivers in shaping abundance‐weighted...
Article
The study of plant trait-environment links is rarely focused on traits that inform on space occupancy and resprouting (both affecting plant persistence), especially in forest understories. Traits that can effectively capture such key functions are associated with clonality and bud banks. We hypothesized that: 1) climate is the main driver of clonal...
Article
Full-text available
Species pool conservation is critical for the stability of ecosystem processes. However, climate and land use changes will likely affect biodiversity, and managers of protected areas are under increasing pressure to monitor native species diversity changes by approaches that are scientifically sound and comparable over time. Here we describe a plan...
Conference Paper
Full-text available
Forests represent the most diverse and complex ecosystems hosting high levels of terrestrial biodiversity, providing needful ecosystem services for human well-being. As an important global attack is pressing this crucial patrimony with an alarming rate, we need an efficient and operative tool to monitor both their conservation and dynamic status. I...
Conference Paper
Full-text available
Plant communities are characterized by continuous fine-scale dynamics, and traitbased approaches can help us explore ecological mechanisms behind such dynamics. The issue of species persistence is of crucial importance to understand the complexity of vegetation dynamics in forest ecosystems and to predict future shifts in species composition and fu...
Article
Italy is among the European countries with the greatest plant diversity due to both a great environmental heterogeneity and a long history of man-environment interactions. Trait-based approaches to ecological studies have developed greatly over recent decades worldwide, although several issues concerning the relationships between plant functional t...

Atmospheric nitrogen (N) pollution is considered responsible for a substantial decline in plant species richness and for altered community structures in terrestrial habitats worldwide. Nitrogen affects habitats through direct toxicity, soil acidification, and in particular by favoring fast-growing species. Pressure from N pollution is decreasing in...
Article
Data uncertainty due to spatial gaps and heterogeneity is a fundamental problem in conservation and environmental planning. Thus, investigation of issues related to data uncertainty contributes to more efficient conservation plans. We evaluated the uncertainty of data related to forest diversity descriptors using a diffusion-based cartogram approac...

Full-text available
In forest ecology, there is a huge experience in the ecological amplitude of tree species, which is commonly represented in so-called ecograms. However, the ecogram axes are purely qualitatively described and scaled. In the study presented here, we try to specify the drought limit in the ecogram for the ten most abundant and economically important...

National forest inventories are a primary source of data for the assessment of forest resources and lastly more often biodiversity at national scales. The diversity of adopted sampling designs and measurements reduces the prospect for a reliable comparison of generated estimates. The ICP Forest dataset represents a unique opportunity for a standard...
Article
The silvicultural management of coppicing has been very common in deciduous forests in many European countries. After decades of decline of this practice, socio-economic changes might induce a revival valuing the biomass as a resource. New insights in the ecological processes that regulate plant diversity are relevant for a sustainable forest manag...
Article
Italy represents a good model region for assessing vegetation responses to changing climate across a broad climatic range, from Mediterranean warm-dry climate to alpine cold-humid climate. We reviewed results of studies analysing the response of natural vegetation to climate change in Italy, published until July 2016 in peer-reviewed journals. Evid...
Article
Though the importance of coppicing for the conservation of forest biodiversity is acknowledged, little is known about flora diversity and how it may be affected by the perceptions, constraints and regulations governing how loggers choose to exploit forest resources. Building on previous research on coppiced forests in the central Italian Apennines,...
