Habitat heterogeneity reduces abundance of invasive mealybugs in subtropical fruit crops

Ángel Plata, Alejandro Tena, Francisco José Beitia, José Paulo Sousa, more

Journal of Applied Ecology > 61 > 2 > 292 - 303

The simplification of agricultural landscapes has been associated with an increase in pest pressure. While monocultures increase the resources available for pests and may facilitate their dispersion, the lack of non‐crop habitats may reduce the resources available for pest natural enemies. Herein, we tested which of these hypotheses, namely ‘resource concentration’ and ‘natural enemies’, can better...

Crop traits drive soil carbon sequestration under organic farming

Pablo García‐Palacios, Andreas Gattinger, Helene Bracht‐Jørgensen, Lijbert Brussaard, more

Journal of Applied Ecology > 55 > 5 > 2496 - 2505

Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also...
