“…For this purpose, the "relevés £ species cover" matrix was multiplied by the "species £ traits" matrix to provide a "relevés £ trait cover" matrix, which formed the basis for the following analyses (Pakeman et al 2009;Catorci et al 2012c).…”

In the Peruvian highlands, climate change and inadequate management are causing land degradation and collapse of the pastoral system. Our research project was aimed at assessing the impact of grazing on dry Puna ecosystem, as understanding and predicting vegetation changes in harsh environments in the face of different disturbance regimes is required for aware and effective management. The study area was the Salinas and Aguada Blanca National Reserve. Two experimental areas were selected, characterized by deep soils with gentle slopes and by shallow soils with steeper slopes. In each area, sites with low and high disturbance regimes were identified, and vegetation was sampled using 10 x 10m plots. The results indicated that the environmental constraints have a marked influence on the species composition, while disturbance quantitatively affects diversity. The floristic changes observed under different disturbance intensities are mainly related to the functional differentiation of the plant communities and to the decrease in vegetation cover. These processes pose a serious risk to the livelihood of the local people, because they can lead to the loss of biodiversity and economic value of pastures, as well as to soil erosion

“…Understory species compositional changes during the regeneration phases after coppicing appeared to be driven by plant functional traits, in particular leaf, clonal and reproductive traits (Canullo et al 2011(Canullo et al , 2017Campetella et al 2011;Catorci et al 2012a). In detail, changes in environmental conditions during the forest regeneration after copping filtered species with high SLA values (Campetella et al 2011;Catorci et al 2012a), short-distance dispersal (Campetella et al 2011), early leaf and flower production (Catorci et al 2012a) and high mobility due to stem-derived clonal growth organs (i.e. hypogeogenous rhizomes; Canullo et al 2011Canullo et al , 2017.…”

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 traits and the environment still lack sufficient empirical evaluation. In order to draw insights on the association between plant functional traits and direct and indirect human and natural pressures on the environmental drivers, here we summarize the existing knowledge on this topic by reviewing the results of studies performed in Italy adopting a functional trait approach on vascular plants, briophytes and lichens. Although we recorded trait measurements for 1418 taxa, our review highlighted some major gaps in plant traits knowledge: Mediterranean ecosystems are poorly represented; traits related to belowground organs are still overlooked; traits measurements for bryophytes and lichens are lacking. Finally, intraspecific variation has been little studied at community level so far. We conclude highlighting the need of approaches evaluating trait-environment relationship at large spatial and temporal scales and the need of a more effective contribution to online databases to tie more firmly Italian researchers to international scientific networks on plant traits.

“…In O. carpinifolia-dominated stands, Catorci et al (2011Catorci et al ( , 2012a found that temporal species turnover followed an ecological cyclic process, characterized by occurrence/disappearance of species groups throughout the coppicing cycle (1 to 25 years after the cut). In particular, light demanding species of dry conditions (mainly annual plants with low seed mass and drought stress tolerance) occur soon after canopy disturbance; partially shade-tolerant species peak in the central phases of the recovery process, while shade-tolerant plants spread out in the late phases of the coppicing rotation cycle.…”

“…Ancient forest species (sensu Hermy et al 1999) are restricted to shelter niches and have been deemed to have a poor ability to re-colonize the understory, due to the too short period of the coppicing rotation cycle. This species turnover reflects, at the community level, a pattern of functional variation (Catorci et al 2012a). In particular, Catorci et al (2012a) found that young stands were differentiated by fast growing species with acquisitive strategies, which reproduce only sexually, with light seeds, summer green and overwintering green leaves, and a long-lasting flowering.…”

Intermediate-aged and mature stands (9-16 and 17-24 years since the last coppicing, respectively) were characterized by traits associated with early leaf and flower production, high persistence in time, and showing retentive strategies aimed at resource storage (e.g., geophytes, spring green leaves, rhizomes, and mesomorphic/hygromorphic leaves).…”

Changes in species and functional composition in the herb layer of sub-Mediterranean Ostrya carpinifolia abandoned coppices

In recent decades, the traditional management of woods has ceased in several parts of the Apennine ridge, with the result that some woods have not undergone forestry for 40-70 years. The research aim was to assess the variation of species and functional composition in the herb layer of Ostrya carpinifolia woods (central Italy), after cessation of the usual management (coppice-withstandards). Using a space-for-time substitution, we compared stands at the end of the usual rotation cycle (20-25 years) with stands not subjected to silvicultural treatments for about 40-45 years and collected environmental and structural data. The main drivers of the herb layer modification, assessed using Ellenberg indicator values analysis and redundancy analysis (RDA), were primarily related to time since the last coppicing and wood structure. Results of indicator species analyses (ISAs) and Wilcoxon rank sum tests indicated that in abandoned coppices, the regenerative processes proceed through the spread of late-successional species, while the light filtering through canopy fosters species usually considered of fringe habitats. The functional strategies revealed by ISA and RDA underlined still stressful conditions in stands at the end of the usual coppicing rotation cycle, which might be thought as a legacy of the post-logging condition, and processes of recovery/maturation of the forest systems in abandoned woods leading to a better spatial and temporal niche partitioning. The preferential distribution of species usually growing in the Apennine beech woods supports the hypothesis that the studied O. carpinifolia woods are secondary forest ecosystems originating from the degradation of mixed beech woods.
