In Mediterranean countries, in the year 2017, extensive surfaces of forests were damaged by wildfires. Vesuvius National Park, multiple summer wildfires burned 88% forest. This unprecedented event an environmentally vulnerable area suggests conducting spatial assessment mixed-severity fire effects for identifying priority areas and support decision-making post-fire restoration. The main objective this study was to compare ability delta Normalized Burn Ratio (dNBR) spectral index obtained...
Abstract Understanding processes controlling forest dynamics has become particularly important in the context of ongoing climate change, which is altering ecological fitness and resilience species worldwide. However, whether communities would be threatened by projected macroclimate change or unaffected due to effect local site conditions still a matter for debate. After all, canopy buffer extremes promote microclimatic conditions, matters functional plant response, act as refugia understory...
Abstract Deciphering the spatial patterns of alpine treelines is critical for understanding ecosystem processes involved in persistence tree species and their altitudinal limit. Treelines are thought to be controlled by temperature, other environmental variables but they have rarely been investigated regions with different land‐use change legacies. Here, we systematically treeline elevation Apennines (Italy) Southern Alps (New Zealand) contrasting human history similar biogeographic...
Abstract As major terrestrial carbon sinks, forests play an important role in mitigating climate change. The relationship between the seasonal uptake of and its allocation to woody biomass remains poorly understood, leaving a significant gap our capacity predict sequestration by forests. Here, we compare intra-annual dynamics fluxes wood formation across Northern hemisphere, from assimilation non-structural compounds their incorporation tissues. We show temporally coupled peaks (GPP) cell...
Abstract Aim High‐elevation forest line or tree is an ecological ecotone representing the upper elevation thermal limit for development. The current position result of past human activity interacting with climatic and topographic conditions. In this study, we investigate how climate, local factors anthropogenic disturbance currently affect distribution. Location Apennine Mountains, 900 km latitudinal gradient along Italian Peninsula. Methods Overall, 302 mountain peaks were studied,...
Wildfires are one of the most important natural disturbances in vegetation biomes. In recent decades, both number and severity fires have significantly increased Mediterranean forests, frequently resulting catastrophic events. this scenario, we aimed to explore flow ecosystem services their related economic value that was disrupted by human-induced megafires forest Vesuvius National Park summer 2017. We adopted an innovative approach merging two methodologies: ecological evaluate status...
Managing forest residues according to the carbon content of soil helps minimize ecological footprint their removal.In Mediterranean mountain ecosystems, unsustainable harvesting wood might contribute land degradation, carbon, and nutrient depletion in soils.This study aimed assess amount biomass that should be left on-site fertility.We estimated availability public Basilicata region Southern Italy by collecting stand-scale inventory attributes from management plans. Subsequently, we...
The continued introduction of non-native insect species, coupled with the rising threat extreme wildfire events, poses significant risks to terrestrial ecosystems and services they offer globally. However, impact invasive phloem-feeding species on fire severity is not well understood, particularly in terms how influence behaviour likelihood crown ignition. Two experimental designs were set up investigate alien tortoise scale (Toumeyella parvicornis) outbreaks have influenced dynamics canopy...
Knowledge of forest ecosystem pattern and process responses to climate change anthropogenic pressure requires innovative tools that combine monitoring modelling tree growth dynamics account for a more sustainable management resources services. In this context, Digital Twins (DTs) emerge as powerful tool allow better interpretation complex models, summarizing large amount data knowledge into comprehensive 3D visualization. A Twin is an evolving representation physical object, in our case...
Abstract Background Fagus sylvatica forms the treeline across Apennines mountain range, with an average elevation of 1589 m a.s.l. Previous studies evidenced that current position in is heavily depressed as a result complex interaction between climatic factors and past human pressure. In this study we correlated fifteen major groups selected climatic, geomorphological, disturbance variables order to investigate detail site-specific features affecting distribution. Results Treeline was lowest...
Plant invasion in forest ecosystems is a serious ecological and economic issue, deserving attention by researchers, managers policy-makers worldwide. Many invasive plants have been reported as early successional species able to colonize disturbed areas following abrupt changes microhabitat resource availability. We investigated disturbance effects of severe windstorm generated wet microburst (hail rain at 160 mm h-1) remarkably affecting the canopy cover an old-growth Quercus ilex urban...
In the Mediterranean region of southern Europe, Castanea sativa Mill. ( ) coppice stands are being invaded by non-native pioneer tree species due to recurrent coppicing and wildfire disturbances. There is a need control spread in coppices their pivotal socio-economic role, however, facilitate this, further research into invasive strategies interactions with disturbances required. The Robinia pseudoacacia L. has widely colonized overaged unmanaged forests Vesuvius National Park, which were...

Litter burning and biological decomposition are oxidative processes co-occurring in many terrestrial ecosystems, producing organic matter with different chemical properties differently affecting plant growth soil microbial activity. We tested the convergence hypothesis, i.e., materials initial chemistry converge toward a common profile, similar effects, as process advances, for decomposition. compared molecular composition, assessed by 13 C NMR, of seven litter types either fresh, decomposed...
Abstract Questions Elevational treelines are expected to shift upwards in response warming climate. However, worldwide upward shifts of inconsistent because local scale factors can affect the temperature. In this study, we explore hypothesis that Apennines, where current altitudinal treeline position is largely depressed past human activity, shrubs act as nurse plants promoting migration Fagus sylvatica . Location A 500–km‐long latitudinal gradient Italy. Methods We selected, along gradient,...
Ectomycorrhizas (ECM) are a common symbiotic association between fungi and various plant species in forest ecosystems, affecting community assemblages at the landscape level. ECMs benefit host plants by increasing surface area for nutrient uptake, defending against pathogens, decomposing organic matter soil. ECM-symbiotic seedlings also known to perform better conspecific soils than other unable carry symbiosis, process referred as plant-soil feedback (PSF). In this study, we tested effects...
In recent decades in the Mediterranean basin there has been a considerable increase both number of wildfires and extent fire-damaged areas, resulting ecological socio-economic impacts. Protected areas are particularly vulnerable many characteristics underpinning their legal protection threatened. Several studies have devoted to mitigating wildfire risks inside protected however often only regard natural heritage losses. Based on adaptive resilience approaches, this work proposes framework...
The boreal Hemisphere has been experiencing increasing extreme hot and dry conditions over the past few decades, consistent with anthropogenic climate change expectations. continental extension of phenomenon calls for tools techniques capable monitoring global to regional scales. In this context, satellite is only system that can satisfy need coverage. main objective we have addressed in present paper capability infrared observations helping monitor vegetation stress due drought heatwaves...
Past anthropogenic disturbances lowered the altitudinal distribution of Mediterranean Fagus sylvatica forests below 2,000 m a.s.l. Accordingly, our current understanding southern range F. is restricted to managed stands this elevation, neglecting relic growing above. This study has shed light on structure and species assemblage an unmanaged relict subalpine stand within core its southernmost glacial refugia at highest elevation limit (2,140 a.s.l.) in Apennines (Italy). Here, tree biometric...
