Aguiar, Susana Tápia, Esteve Llop, Paula Lopes, Artur R.M. Serrano, Ana I. Leal, Otilia Correia, Paula Matos, Ana Rainho, Cristina Branquinho, Ricardo A. Correia, Jorge M. Palmeirim
Wood-pastures are grazed systems resulting from a long-term use of natural woodlands by humans. These social-ecological systems, covering vast areas of Europe and other temperate regions, have both high biodiversity and economic values, so many are classified as High Nature Value Farmlands. However, in some regions a loss of spatial heterogeneity threatens this natural value. We investigated the potential

Nematode metabolic footprints, ecological and functional indices in tropical maize-beans agro-ecosystems under different farming practices Acta Oecol. (IF 1.22) Pub Date : 2020-08-11 Samuel Maina, Hannah Karuri, Rossa Nyoike Ng'endo
Maize and beans contribute significantly to food security in Kenya. Farming practices used in production of these crops may affect nematode community assemblages and influence agricultural productivity. Information on response of nematofauna, particularly free-living nematodes, under various agronomic practices in Kenyan maize-beans intercrop is scarce. This study reports on the effects of farming

Biotic interactions and limitations to explain their effects on a neotropical savanna plant community Acta Oecol. (IF 1.22) Pub Date : 2020-08-06 D.B. Chagas, A. Rapini, R.G. Collevatti
Ecological communities result from the interaction of different sorts of biotic and abiotic processes. Here, we assess the effects of two target plants that show different interactions with their surrounding (neighborhood) vegetation, on species richness, abundance, and diversity of communities, to address the influence of different biological processes in the formation of a plant community. We compared
