Economic Evaluation of Pollination Services Comparing Coffee Landscapes in Ecuador and Indonesia

Biodiversity conservation through land-use systems on private land is becoming a pressing environmental policy issue. Agroforestry, such as shade-coffee production, contributes to biodiversity conservation. However, falling coffee prices force many coffee growers to convert their sites into economically more attractive land uses. We performed an economic evaluation of coffee pollination by bees...

Effects of patch size and type of coffee matrix on ithomiine butterfly diversity and dispersal in cloud-forest fragments.

Determining the permeability of different types of landscape matrices to animal movement is essential for conserving populations in fragmented landscapes. We evaluated the effects of habitat patch size and matrix type on diversity, isolation, and dispersal of ithomiine butterflies in forest fragments surrounded by coffee agroecosystems in the Colombian Andes. Because ithomiines prefer a shaded ...

The Economics of Managed Landscape Conservation

Historically, both conservation research and policy have concentrated on primary forests. Increasingly, however, the focus is being broadened to include human-dominated landscapes, such as agroforestry systems, managed forests, hedgerows, and fallow lands. One reason is that considerable research has demonstrated that such landscapes can provide many of the same ecological services as primary f...

Connecting sustainable agriculture and wildlife conservation: Does shade coffee provide habitat for mammals?

Shade coffee systems provide a refuge for biodiversity; however, research has been dominated by bird and insect studies with few studies that have focused on mammals living within coffee-dominated landscapes. Relative to other taxa studied, only 5% of the articles published on coffee and biodiversity pertain to mammals. We surveyed non-volant mammals, with an emphasis on small mammals, in 3 cof...

Coffee Agroforests Remain Beneficial for Neotropical Bird Community Conservation across Seasons

Coffee agroforestry systems and secondary forests have been shown to support similar bird communities but comparing these habitat types are challenged by potential biases due to differences in detectability between habitats. Furthermore, seasonal dynamics may influence bird communities differently in different habitat types and therefore seasonal effects should be considered in comparisons. To ...
