There is a current need to develop alternative forest management practices to clear\uffe2\uff80\uff90cutting in order to simultaneously promote timber production, preserve biodiversity and enhance forest health and economic value. Here, we experimentally manipulated a Quercus pubescens forest to evaluate the effects of a thinning gradient (i.e., partial tree removal) ranging from 25% to 75% basal area reduction and a logging residue retention (i.e., slash management) on ground\uffe2\uff80\uff90dwelling spider abundance and species richness. These two alternative management practices were compared with clear\uffe2\uff80\uff90cutting (100% basal area reduction) and logging residue exportation methods. In each treatment, we recorded soil temperature and moisture, understorey vegetation cover, richness and functional traits and mesologic factors describing habitat characteristics. We found clear\uffe2\uff80\uff90cutting had a stronger effect than thinning on the microclimatic conditions, i.e., higher temperatures, drier soils and reduced forest buffering capacity. The 25% thinning intensity was sufficient to drastically reduce both spider abundance and richness, but we did not find a more significant reduction when more intensive cutting was applied. This result suggests a threshold effect in the response of spiders to cutting. Significant changes in the functional diversity of understory plant communities in response to basal area were observed, along with strong effects on spider communities. Unexpectedly, slash retention appeared to have little or no effect on the forest microclimate, spider abundance and species richness. This work is intended for forest managers and policymakers and aims to contribute to the development of relevant practices that address current environmental and economic challenges.

Among soil organisms, soil nematodes can serve as valuable bioindicators to assess the impact of forest management on soil biodiversity and soil functioning. Consequently, we investigated two related questions in a Mediterranean Pinus halepensis Mill. forest located in southeastern France. First, how do soil nematodes respond to forest management practices? Second, can forest management practices help modulate the effects of Mediterranean summer drought on these soil organisms? We conducted a field experiment in which we explored the influence of two forest management techniques-tree thinning (intense, moderate, or absent) and understory removal (shrubs present or absent)-on soil nematodes before and after the summer drought. We found that only total and bacterivorous nematode abundances were positively influenced by the forest management practices. The highest values were observed under conditions of intense thinning combined with shrub presence, with an average of 97,509 individuals per kg of dry soil. In contrast, the abundances of all nematodes, with the exception of predaceous nematodes, were lower after the summer drought with a reduction ranging from-55 % to-82 %. Total, bacterivorous, and fungivorous nematode abundances were less negatively affected by the summer drought under conditions of moderate thinning when shrubs were present versus absent. More generally, we discovered that bacterivorous and fungivorous nematodes were particularly sensitive to the forest management practices and the summer drought. It is thus apparent that habitat alterations induced by forest management can strongly affect nematode community structure and could therefore prompt shifts in ecosystem functioning. Finally, this study highlights that, in forests, understory vegetation can have significant positive impacts on soil nematode populations when severe dry periods occur.", "keywords": ["2.

The biomass of wood, foliage, and roots was highest in the unthinned control stands, lowest in stands measured 3 years after thinning, and intermediate in the stands measured 16 years following the same prescription. While total wood net primary production (NPP) followed the same pattern as biomass across treatments, an apparent doubling of shrub foliage NPP in the 3 years following overstory thinning reduced the impacts of thinning on total foliage NPP. Similarly, reductions in coarse root NPP associated with tree removal were largely offset by increases in fine root production. Compensatory NPP by shrubs and fine roots increased the light use efficiency of thinned stands 60% over that of unthinned plots. Both soil respiration and the decomposition of aboveground dead wood appeared conserved across all treatments.

Mineral soil measurements were restricted to the top 10 cm. Data were analyzed with both multivariate and univariate analyses of variance. Multivariate analyses were conducted with and without soil mesofauna or forest floor mesofauna, as data for those taxa were not collected on some sites. In multivariate analysis with soil mesofauna, the model giving the strongest separation among stand types (P = 0.019) included abundance and richness of soil mesofauna and anaerobic mineralizable nitrogen. The best model with forest floor mesofauna (P = 0.010) included anaerobic mineralizable nitrogen, soil moisture content, and richness of forest floor mesofauna. Old growth had the highest mean values for all variables, and in both models differed significantly from mature stands, while the latter did not differ. Old growth also averaged higher percent soil organic matter, and analysis including that variable was significant but not as strong as without it. Results of the multivariate analyses were mostly supported by univariate analyses, but there were some differences. In univariate analysis, the difference in percent soil organic matter between old growth and thinned mature was due to a single site in which the old growth had exceptionally high soil organic matter; without that site, percent soil organic matter did not differ between old growth and thinned mature, and a multivariate model containing soil organic matter was not statistically significant. In univariate analyses soil mesofauna had to be compared nonparametrically (because of heavy left-tails) and differed only in the Siskiyou Mountains, where they were most abundant and species rich in old growth forests. Species richness of mineral soil mesofauna correlated significantly (+) with percent soil organic matter and soil moisture, while richness of forest floor mesofauna correlated (+) with depth of the forest floor. Composition of forest floor and soil mesofauna suggest the two groups represent a single community.

The removal of biomass in areas previously degraded by acid deposition may result in the deficiency of Ca and Mg because of their low content in forest soil. On the other hand, thinning supported the faster growth of trees left after thinning and consequently faster biomass and nutrient accumulation.", "keywords": ["thinning", "kru\u0161n\u00e9 hory mts.", "0401 agriculture", " forestry", " and fisheries", "Forestry", "04 agricultural and veterinary sciences", "SD1-669.5", "15.

The economic feasibility of different management strategies of hybrid aspen coppice stands has not yet been comprehensively evaluated in Northern Europe. We compared the land expectation values (LEVs) of hybrid aspen coppice stands managed according to four scenarios: three early thinning methods (corridor, cross-corridor and single-tree) followed by conventional management and intensive bioenergy production (repeated harvests in 5-year rotations) over a 25-year period in hemiboreal Estonia. We considered the historic price volatility of aspen wood assortments under various discount rates (1\uffe2\uff80\uff9320%). We found that the 25-year rotation with different early thinning methods was more profitable than short bioenergy cycles in the case of low discount rates (&lt;5%). The LEV of short coppice cycles for only bioenergy production became more profitable in comparison with those by thinning methods, when higher discount rates (&gt;10%) were applied. Hybrid aspen coppice stands can be managed profitably, but more risks are taken when the management strategy focuses only on bioenergy production.</p>", "keywords": ["Estonia", "coppice forestry", "forest thinning strategies", "04 agricultural and veterinary sciences", "15.

However, the underlying mechanisms, and the relative importance of carbon  input and decomposition in regulation of soil carbon dynamics are poorly  understood. We examined whether interactive effects of forest  fertilization and thinning on carbon stocks in the topsoil of boreal  forests were linked to changes in fungal community composition, biomass,  and enzyme activities, in a long-term fertilization and thinning  experiment distributed across 29 Pinus sylvestris forests along a 1300 km  latitudinal transect in Sweden. Nitrogen fertilization increased fungal  biomass, particularly towards the north and mainly by promoting root  associated Ascomycetes, but the response was moderated by thinning. Fungal  biomass correlated positively with carbon stocks in the organic topsoil.  However, ectomycorrhizal Cortinarius species were reduced in abundance by  fertilization and correlated negatively with carbon stocks. Plausibly,  increased soil carbon stocks after fertilization are linked to increased  input of carbon in the form of root-associated mycelium combined with loss  of ectomycorrhizal decomposers within the genus Cortinarius. These fungal  responses to fertilization may mediate a natural climate solution by  promoting carbon sequestration in the organic topsoil, but the effect of  fertilization may also be undesired from a biodiversity perspective.", "keywords": ["Ectomycorrhiza", "13.
