International audience; CONTEXT: Fostering diversity within agricultural systems can substantially contribute to improved food security among smallholder farmers. Agroforestry parklands are diverse agricultural landscapes where trees can provide an array of ecosystem se...

Abstract The two most important activities in maize breeding are the development of inbred lines with high values of general combining ability (GCA) and specific combining ability (SCA), and the identification of hybrids with high yield potentials. Genomic selection (GS...

In the present work a taxonomic analysis of Mexican edible forest insects along with their host plants have been reviewed. We have recorded 73 insect species under 26 families and 6 orders, namely: Orthoptera, Hemiptera-Heteroptera, Lepidoptera, Coleoptera, Diptera and...

RESUMEN Los microorganismos son de gran interés porque colonizan todo tipo de ambiente, sin embargo, uno de los problemas al que nos enfrentamos para conocer su diversidad biológica es que no todos los microorganismos son cultivables. El desarrollo de nuevas tecnologías...

RESUMEN En Ecuador las especies exóticas invasoras (EEI) provocan consecuencias negativas en los aspectos ecológicos, económicos y de seguridad alimentaria. Los agroecosistemas hacen parte de los sectores productivos a nivel mundial, pero son vulnerables a sufrir invasi...

Abstract Own production contributes much of the food supply in smallholder production systems in low‐ and middle‐income countries like Ethiopia. Understanding the potential as well as constraints of these production systems in terms of nutrient supplies is thus a critic...

Land-use/cover change is the major cause of terrestrial ecosystem degradation. However, its impacts will be exacerbated due to climate change and population growth, driving agricultural expansion because of higher demand of food and lower agricultural yields in some tro...

Abstract Digital extension tools (DETs) include phone calls, WhatsApp groups and specialised smartphone applications used for agricultural knowledge brokering. We researched processes through which DETs have (and have not) been used by farmers and other extension actors...

Estimating total aerial biomass, and carbon, in tropical forests is a critical task for forest management and carbon markets, for which various allometric models have been developed for this purpose. Pantropical, multi-species and multi-site models, try to develop estim...

Los ecosistemas terrestres tienen almacenes en la biomasa aérea (B) de alta importancia para acciones de mitigación del cambio climático a través de mecanismos tales como REDD+. Para obtener posibles compensaciones financieras por evitar deforestar o degradar los bosque...
