Canopy gap impacts on soil organic carbon and nutrient dynamic: a meta-analysis

Annals of Forest Science, Год журнала: 2024, Номер 81(1)

Abstract Key message The forest canopy gaps, formed by natural or anthropogenic factors, have been found to reduce soil carbon content and increase nutrient availability. magnitudes of these effects observed with gap age size, are largely influenced changes in temperature, precipitation, solar radiation. Context Local studies illustrated the influence gaps on spatial heterogeneity nutrients, playing a pivotal role driving regeneration succession. Nevertheless, it remains unknown whether response formation is consistent across ecosystems at global scale. Aims aim this paper assess homogeneity responses nutrients following among wide array climatic regions. Methods We performed meta-analysis synthesizing 2127 pairwise observations from 52 published articles quantify physical, chemical, microbial variables resulting creation forests plantations spanning tropical boreal Results Canopy resulted significant decrease organic ( C org ) mic ). concentrations ammonium (NH 4 + ), nitrate (NO 3 − available phosphorus (available P) increased creation.

Forest degradation modifies litter production, quality, and decomposition dynamics in Southern temperate forests

Introduction Anthropic disturbances are driving unprecedented changes in forest ecosystem functions and biogeochemical processes, hindering the forests’ benefits to society. Litter decomposition is one of most critical processes that regulate carbon nutrient cycling. However, how degradation affects litter elemental dynamics requires further examination. The main objective this study was evaluate effect on production C,N, P a temperate south-central Chile. Methods traps bags were installed three Long Term Research Forest Plots (LTER) representing different conservation states: mature, secondary, degraded Nothofagus forests. Results Discussion total input varied between 3.5 1.1 Mg ha– 1 year– mature forests, respectively. We found highest lignin levels lowest forest. In forest, 44% initial decomposed, while it only reached 7%. Decomposing showed C:N C:P ratios year. balance inputs outputs yielded more substantial accumulation Conclusion Our results strongly suggest anthropogenic altered quality decreasing decomposition.

Global forest gaps reduce litterfall but increase litter carbon and phosphorus release

Abstract Ongoing global climate change and conventional forestry have led to a dramatic increase in new forest gaps, predicted strongly impact litter turnover nutrient cycling. Here we synthesized 8739 paired observations quantify the impacts of naturally occurring artificially created gaps on litterfall, decomposition, release carbon nutrients. Globally, decreased annual litterfall by 29.5% remaining phosphorus 5.6%, while decomposition increased 0–20% mass loss interval. Climate quality showed major contribution gap effects with characteristics further influencing nutrients during decomposition. Our results uncovered potential escalating reducing sequestration, providing support for inclusion into dynamic models improve predictions ecosystem material cycling responses ongoing change.

Bark beetles as ecosystem engineers: triggered tree mortality rearranges the assemblage of Tree-related Microhabitats in old-growth coniferous forest

Abstract Although species with ecosystem engineering capabilities like woodpeckers, ungulates or saproxylic insects may initiate the formation of Tree-related Microhabitats (TreMs), their overall impact on TreM assemblages remains unexplored. Bark beetle activity can increase tree mortality, accelerating emergence canopy gaps altered composition, stand structure and deadwood resources, all which influence profiles cascade biodiversity. We investigated assemblage in a strictly-protected old-growth Norway spruce Picea abies forest Tatra Mountains (Carpathians, S Poland), comparing bark beetle-induced undisturbed closed-canopy reference sites. richness, density diversity did not differ between sites, frequency woodpecker cavities, splintered stems, cracks, pockets, shelters, fruiting bodies polypore fungi epiphytic ferns was higher gap assemblage. In contrast, exposed sapwood, shaded dead branches, tops, coarse bark, root buttress cankers, resin runs microsoil crown were correlated living standing trees related to previous activity. total abundance diversity, but by hosting more TreMs, locally composition. Our study underlines importance beetles as drivers heterogeneity temperate coniferous montane forests. Highlights TreMs forests are abundant less diverse than deciduous ones Canopy have distinct profile compared intact hot-spots certain Saproxylic 3–9 times Tree mortality triggered increases habitat
