The checklist of the non-marine gastropod fauna summarizes the known species and subspecies that are recognized from México and Central America. It is an annotated list of 1800 terminal taxa presented in a hierarchical framework. These include 1502 native species plus 278 native subspecies, and 20 introduced species. The native species include 175 aquatic operculates, 84 aquatic pulmonates, 130 terrestrial operculates, and 1112 terrestrial pulmonates. In most cases in order to be as objective as possible the list uncritically records the most recent assignment of terminal taxa. In a few instances some changes are deemed necessary. For higher-level changes competing schemes are treated equally. In cases of terminals and higher taxa, readers are directed to the systematic works that discuss relevant taxonomy. It is anticipated that the annotated list will be a useful resource for everyone interested in non-marine gastropods and their nomenclature. In addition to clarifying some issues or points of confusion, this list should also provide an impetus for future work aimed at clarifying and resolving areas of taxonomic disagreement and/or uncertainty, and to make better known the non-marine molluscan fauna of México and Central America.

“…Research and studies on interactions between weeds as host plants, as ecological indicators, as a source of biomass and allelopathic agents in tropical cropping systems have multiplied. However, the need for weed management continues to be investigated in order to find the most effective way to eradicate species or populations of these plants in tropical agricultural ecosystems [6].…”

Introducción- El impacto más crítico de las arvenses es el efecto negativo sobre las plantas cultivadas ejercido a través de la competencia por recursos limitados y las alelopatías. Objetivo-. Caracterizar la diversidad de especies de arvenses en 60 fincas de pequeños agricultores de cinco municipios de Boyacá previstos para policultivos. Metodología-. La investigación se desarrolló en 60 fincas de cinco municipios del Departamento: Aquitania, Belén, Garagoa, Panqueba y Soatá, en cada una se muestrearon dos parcelas de 0,5 ha donde se determinó en dos marcos de 1m2 las arvenses presentes. Resultados-. Se observó la presencia de 109 especies de arvenses ubicadas en 93 géneros y en 38 familias botánicas, siendo las más representativas Poaceae con 18 especies, Asteraceae con 15 especies y Fabaceae con 9. Las familias Amarantaceae Apiaceae, Lamiaceae, Oxalidaceae, Poligonaceae y Solanaceae estuvieron representadas por 4 especies. Las fincas se agruparon en 3 o 4 grupos en cada municipio de acuerdo a los indicadores de biodiversidad de las arvenses, mientras que los municipios formaron tres grupos. Conclusiones- Desde el punto de vista de su importancia agrícola las especies que con más frecuencia estuvieron presentes en los municipios fueron: P. clandestinum, Sonchus oleraceus, Trifolium repens y Rumex crispus. En general la riqueza de especies a nivel de finca fue baja, la equidad media y la dominancia alta, mientras que a nivel municipal se apreció una alta riqueza de especies, indicadores medios de diversidad y equidad, y baja dominancia.

Towards a General Theory of Agricultural Knowledge Production: Environmental, Social, and Didactic Learning

Social scientists and input producers alike have seen farmer decision making as driven by environmental learning based on experimentation and empirical observation. A more robust body of theory influenced by behavioral ecology sees a major role for social learning based on emulation of models selected on social criteria, although the relationship between these learning modes is not well understood. But a larger problem is that these perspectives ignore what is here termed didactic learning, whereby various parties bring instruction to the farm. Although not previously theorized, didactic learning is often crucial in agricultural learning and also distinct because it is driven by off-farm interests.
