Climate-driven growth dynamics and trend reversal of Fagus sylvatica L. and Quercus cerris L. in a low-elevation beech forest in Central Italy.

In highly climate-change-sensitive regions, such as the Mediterranean, increasing knowledge of climate-driven growth dynamics is required for habitat conservation and forecasting species adaptability under future climate change. In this study, we test a high spectrum of climatic signals, not only monthly and seasonal but also on a multi-year scale and include the single tree analysis to answer this issue, focusing on a low-elevation thermophilic old-growth beech forest surrounding the Bracciano Lake in Central Italy. Through a dendroecological and isotope analysis, we evaluate both short- and long-term sensitivity of F.

Decomposition of black pine (Pinus nigra J. F. Arnold) deadwood and its impact on forest soil components.

Deadwood decomposition is a complex and dynamic process with large implications for biogeochemical cycling of carbon (C) and nitrogen (N) in forest soil and litter. Moreover, it affects functional and structural diversity of fungal and bacterial communities in these components. Mesocosms with deadwood blocks at progressive decay classes were set in a black pine forest and incubated for 28 months in the field with the aim to assess the impact of deadwood decomposition on i) CO, CH and NO fluxes; ii) C and N pools and allocation among deadwood, litter and soil; iii) the fungal and bacterial structural diversity and activity.

Short-term effects of thinning on soil CO, NO and CH fluxes in Mediterranean forest ecosystems.

In Mediterranean ecosystems an increasing demand for in situ trace gas exchange data is emerging to enhance the adaptation and mitigation strategies under forest degradation. Field-chamber green-house gas fluxes and site characteristics were analysed in two Mediterranean peri-urban pine forests showing degradation symptoms. We examined the effect of different thinning interventions on soil CO, CH and NO fluxes, addressing the relationships with the environmental variables and C and N contents along forest floor-soil layers.

Intra-annual raw basal area increments (early-wood and late-wood) of subsp. Poiret trees from southern Italy at the pines׳ mesic to xeric distribution range.

This article contains tree rings data related to the research article entitled "An intra-stand approach to identify intra-annual growth responses to climate in subsp. Poiret trees from southern Italy" (Mazza et al., 2018).
