The Cultural Context of Forest Degradation in Adjacent Purépechan Communities, Michoacán, Mexico

Background

This study aims to understand the relationship between cultural and ecological drivers contributing to change in forest land use patterns by comparing two adjacent indigenous communities in the volcanic plateau region of Michoacán, Mexico. The study suggests that both cultural and ecological processes must be studied together to best understand the cultural causes of forest change and accurately assess ecological consequences.

Evaluation of Native Tree Species for the Rehabilitation of Deforested Areas in a Mexican Cloud Forest

background

This study examines the survival of four native tree species used in mixed-experimental plantations in the tropical montane forest of Veracruz, Mexico (1300-1900m). Tropical montane covers only 1% of land surface in Mexico but contains ~ 10% of all flowering plants. In Veracruz, forest fragments occupy on 10% of the oringinal forest cover.

Germinación de semillas de seis especies de Bursera del centro de México

Este artículo evaluó la influencia de la temperatura y el almacenamiento en la germinación de seis especies de Bursera nativas a México (B. bicolor, B. bipinnata, B. cipallifera, B. fagaroides, B. glabrifolia, B. grandifolia). Encontraron alta proporciones de semillas vanas en tres especies. Había un aumento en la germinación dentro de condiciones con una temperatura fluctuante (32-18 °C) en comparación con las semillas expuestos a una temperatura constante (25 °C). No hubo diferencias significativas en la germinación entre las especies con semillas almacenadas durante seis meses a temperatura ambiente y en refrigeración (25 °C). Después de cuatro meses, la germinación de Bursera glabrifolia, B. copallifera y B. bicolor fue del 30 a 60%.

Impacts of Early- and Late-seral Mycorrhizae during Restoration in Seasonal Tropical Forest, Mexico

background

This study examines the degree to which arbuscular mycorrhizal fungi (AMF) are associated with early vs. late successional forests in Quintana Roo, Mexico. It considers how such fungi aid seedling growth of six native early-, mid- or late-successional tree species. The researchers hypothesize that the application of mycorrizae associated with a tree species' associated successional sere will better promote that species' seedling growth and that associated AMF are therefore key for forest restoration success in degraded or disturbed areas.

Successional Change and Resilience of a Very Dry Tropical Deciduous Forest Following Shifting Agriculture

Background

Given substaintial conversion of very dry tropical deciduous forests in Mexico to agricultural and other land uses, this study examines forest succession over time in such ecosystems. The study was conducted near Nizanda, Oaxaca, Mexico with 26°C average temperatures and 900 mm average rainfall.
