Soil organic matter (SOM) plays a crucial role in nutrient cycling and soil carbon (C) accumulation, which strongly depend on the quality quantity of plant litter input. However, mechanisms underlying SOM dynamics relation to diversity are poorly understood, but essential promote C sequestration soils. The aim study was investigate influence willow species identity, mixture cultivation site pools, chemical composition thermal stability. Using pyrolysis-field mass ionization spectrometry (Py-FIMS) we examined upper topsoil (0-10 cm) two 7-year-old experimental sites Germany Sweden, consisting pure mixed stands biomass willows (Salix spp.). Our results showed significant variability across for both identity effects accumulation chemistry. Yearly significantly (p < 0.05) higher variety ‘Loden’ (1.02 Mg ha-1 year -1 C) compared ‘Tora’ (0.54 Rostock. At Uppsala site, Loden Tora exhibited yearly rate 0.55 0.65 year-1 C, respectively. Willow affected stability at sites. Consistent patterns were few; abundance free fatty acids lower under Loden, suberin had greater Tora. Mixing some one studied sites, no effect either site. Overall, site-effect strongest quality. findings emphasize significance site-specific context shaping chemistry plantations.

Background: Forest mulch is the habitat of decomposer organisms and protects soil from erosion. In seasonally dry tropical forest, this organic layer lost due to elimination vegetation cover resulting agricultural activities but could be recovered through restoration intervention. Prediction: The seasonality rainfall, composition species richness plantings recruitment in areas under explain accumulation mass. Study site dates: Four-year-old forest Quilamula, Sierra de Huautla, Morelos. Methods: Four samplings natural succession seven planting combinations that include between three 12 (six legumes six non-legumes). Results: Including succession, average mass was 6.5 Mg/ha. As expected, greater compared middle season what recorded at end rainy season. Furthermore, positively related number planted highest where lowest exotic grass Andropogon gayanus recorded. Conclusions: Restoration favor recovery litter by increasing its with planted, while invasion grasses reduces it.

Soil organic matter (SOM) is essential for nutrient cycling and soil carbon (C) accumu-lation, both of which are heavily influenced by the quality quantity plant litter. Since SOM dynamics in relation to diversity poorly understood we investigated effects willow variety mixture, site on C stocks, chemical composition ther-mal stability. Using pyrolysis-field ionization mass spectrometry analysed top 10 cm from two 7-year-old experimental sites Germany Sweden, with monocultures mixtures varieties (Salix spp.) belonging different species. Overall, had strongest effect quality. Results showed significant variability across identity mixture accumulation chemistry. In German (Ros-tock), yearly was higher (p &lt; 0.05) ‘Loden’ (1.0 Mg ha-1 year-1) compared ‘Tora’ (0.5 year-1), whilst Swedish (Uppsala), ex-hibited similar rates around 0.6 year-1. Willow significantly affected at sites, while mixing minor effects. Our findings emphasize significance site-specific context or species shaping plantations.

Abstract Transformation of forests into agricultural lands threatens biodiversity and ecosystem functions globally. In the hotspot Madagascar, key along with highly endemic flora fauna are under threat. Comprehensive studies identifying proximate drivers lacking, no accounting for species richness across multiple taxa. We assess how plot-scale stand structural attributes (basal area, leaf area index, diameter diversity, tree richness) landscape-scale forest cover affect (species butterflies, ants, birds, amphibians, reptiles, herbaceous plants, multidiversity) (soil organic carbon, predation rate, acoustic diversity multifunctionality) in tropical mosaic landscape northeastern Madagascar. Across a prevalent land-use gradient region, we sampled five woody types: old-growth forest, fragment, fallow, forest-derived fallow-derived vanilla agroforests. Complexly structured stands larger basal higher promoted greater multidiversity certain functions. Landscape-scale significantly favored, particularly, bird richness. Our models explained 70% variance multidiversity, 26% 43% multifunctionality. Significant effects directions our predictors differed between taxa but were univocally positive findings highlight that simplified structure, resulting from change, substantially reduces this historically forested region. Conservation actions should aim at maintaining complex structure agroforests, while restoration interventions focus on re-building such structures.

Abstract The capacity of forests to sequester carbon in both above‐ and belowground compartments is a crucial tool mitigate rising atmospheric concentrations. Belowground storage strongly linked soil microbial communities that are the key drivers heterotrophic respiration, organic matter decomposition thus nutrient cycling. However, relationships between tree diversity properties such as biomass respiration remain unclear with inconsistent findings among studies. It unknown so far how spatial configuration depth affect relationship richness properties. Here, we studied distribution context experiment by measuring subtropical (BEF‐China experiment). We sampled cores at two depths five locations along transect trees mono‐ hetero‐specific pairs native deciduous species Liquidambar formosana Sapindus saponaria . Our analyses showed decreasing increasing distance from mono‐specific pairs. calculated overyielding – which higher or than expected monocultures analysed patterns transect. found no general across all sampling positions depths. Yet, encountered pattern significant close L. underyielding S. trees. similar only differed strength their effects. results highlight importance small‐scale variations tree–tree interaction effects on functions calling for better integration within‐plot variability understand biodiversity–ecosystem functioning relationships.

Soil organic matter (SOM) is essential for nutrient cycling and soil carbon (C) accumulation, both of which are heavily influenced by the quality quantity plant litter. Since SOM dynamics in relation to diversity poorly understood, we investigated effects willow variety mixture, site on C stocks, chemical composition thermal stability. Using pyrolysis-field ionization mass spectrometry (Py-FIMS), a method stepwise degradation ultrahigh vacuum combined with soft high electric field, followed mass-spectrometric separation detection molecular ions, analyzed top 10 cm from two 7-year-old experimental sites Germany Sweden. Monocultures mixtures varieties (Salix spp.) belonging different species were grown at plots. Overall, had strongest effect quality. The results showed significant variability across identity mixture accumulation chemistry. In German (Rostock), yearly was higher (p < 0.05) ‘Loden’ (1.0 Mg ha−1 year−1) compared ‘Tora’ (0.5 year−1), whilst Swedish (Uppsala), exhibited similar rates around 0.6 year−1. Willow significantly affected sites, while mixing minor effects. Our findings emphasize significance site-specific context shaping plantations.
