Data from Soil chemistry turned upside down: a meta-analysis of invasive earthworm effects on soil chemical properties

Olga Ferlian, Madhav P. Thakur, Alejandra Castañeda González, Layla M. San Emeterio, Susanne Marr, Barbbara Da Silva Rocha & Nico Eisenhauer
Recent studies have shown that invasive earthworms can dramatically reduce native biodiversity, both above and below the ground. However, we still lack a synthetic understanding of the underlying mechanisms behind these changes, such as whether earthworm effects on soil chemical properties drive such relationships. Here, we investigated the effects of invasive earthworms on soil chemical properties (pH, water content, and the stocks and fluxes of carbon, nitrogen, and phosphorus) by conducting a meta-analysis. Invasive earthworms...

Data from: Recommendations for assessing earthworm populations in Brazilian ecosystems

Earthworms are often related to fertile soils and frequently used as environmental quality indicators. However, to optimize their use as bioindicators, their populations must be evaluated together with environmental and anthropogenic variables regulating earthworm communities. In this review we identify the earthworm, soil chemical, physical, environmental and management-related variables evaluated in 124 published studies that quantified earthworm abundance (>7300 samples) in 765 sites with different types of climate, soils, land use and management systems in...

Cocoa agroforest multifunctionality and soil fertility explained by shade tree litter traits

Marie Sauvadet, Stéphane Saj, Grégoire Freschet, Jean-Daniel Essobo, Séguy Enock, Thierry Becquer, Philippe Tixier & Jean-Michel Harmand
Manipulating plant functional diversity to improve agroecosystem multifunctionality is a central challenge of agricultural systems worldwide. In cocoa agroforestry systems (cAFS), shade trees are used to supply many services to farmers, yet their impact on soil functioning and cocoa yields is likely to vary substantially among tree species. Here, we compared the impact of five shade tree species (Canarium schweinfurthii (Canarium), Dacryoides edulis (Safou), Milicia excelsa (Iroko), Ceiba pentandra (Kapok tree), Albizia adianthifolia (Albizia)) and...

Data from: Cross-species hybridization and the origin of North African date palms

Date palm (Phoenix dactylifera L.) is a major fruit crop of arid regions that were domesticated 7,000 y ago in the Near or Middle East. This species is cultivated widely in the Middle East and North Africa, and previous population genetic studies have shown genetic differentiation between these regions. We investigated the evolutionary history of P. dactylifera and its wild relatives by resequencing the genomes of date palm varieties and five of its closest relatives....

Data from: Contribution of European forests to safeguard wild honey bee populations

Fabrice Requier, Yoan Paillet, Fabien Laroche, Benjamin Rutschmann, Jie Zhang, Fabio Lombardi, Miroslav Svoboda & Ingolf Steffan-Dewenter
Recent studies reveal the use of tree cavities by wild honey bee colonies in European forests. This highlights the conservation potential of forests for a highly threatened component of the native entomofauna in Europe, but currently no estimate of potential wild honey bee population sizes exists. Here, we analysed the tree cavity densities of 106 forest areas across Europe and inferred an expected population size of wild honey bees. Both forest and management types affected...

LeWoS: A universal leaf‐wood classification method to facilitate the 3D modelling of large tropical trees using terrestrial LiDAR

Di Wang, Stéphane Momo Takoudjou & Eric Casella
1. Leaf-wood separation in terrestrial LiDAR data is a prerequisite for non-destructively estimating biophysical forest properties such as standing wood volumes and leaf area distributions. Current methods have not been extensively applied and tested on tropical trees. Moreover, their impacts on the accuracy of subsequent wood volume retrieval were rarely explored. 2. We present LeWoS, a new fully automatic tool to automate the separation of leaf and wood components, based only on geometric information at...
