“…Management intensification can alter the structure and complexity of trees in cropping systems as well as increased use of agrochemicals, and both changes can affect the potential for these systems to harbor biodiversity (De la Mora et al, 2013;Bisseleua et al, 2009;García Estrada et al, 2006;Klein et al, 2003;Moguel and Toledo, 1999). Transformation of complex agroecosystems to monocultures results in losses of bird, ant, bee, and bat diversity (García Estrada et al, 2006;Klein et al, 2002;Perfecto et al, 1997;Perfecto and Vandermeer, 2002;Philpott et al, 2008a).…”

“…Agrochemical applications negatively affect ant richness and abundance (Andersen et al, 2002;McCoy et al, 2001) and negatively affect natural enemies thereby reducing predation rates (Leslie, 1977;McCoy et al, 2001). In our study area, agrochemicals including endosulfan, chlorpyrifos, and copper sulfate are sprayed to control insect pests (e.g., CBB) and fungal diseases (García Estrada et al, 2006;Jaramillo et al, 2006). a Ant species are organized from the morphospecies that removed the most prey items across all sites to those that removed fewer prey items.…”

A B S T R A C TAgricultural management and the landscape surrounding farms impact biological diversity and ecosystem services, such as predation, in agroecosystems. Diversified coffee agroecosystems harbor biodiversity, and maintain ecosystem services, especially when in complex landscapes, and when diversity of organisms providing services is maintained. But few have examined whether biological diversity, per se, or the local and landscape habitat features are stronger drivers of the services provided. We studied the relationships between local characteristics associated with agricultural management (vegetation complexity and agrochemical use), landscape surroundings of farms, abundance and richness of ants, and predation services provided by ants in a tropical coffee landscape. Specifically, we tested whether: (1) ants remove prey items and prey removal differs in the wet and dry season, (2) ant prey removal differs in farms that vary in vegetation complexity and agrochemical use, (3) ant prey removal differs with changes in ant abundance and species richness, and (4) ant prey removal differs with changes in local and landscape characteristics. We established sites across a range of coffee management systems, at varying distances to forest fragments, and in forest fragments and examined prey removal by ants on the ground, coffee branches, and shade tree trunks in the wet and dry season. Prey removal did not differ with season. Prey removal on the ground increased within increases in ant abundance and richness, and number of hollow coffee twigs. Prey removal on coffee plants decreased with vegetation complexity, but increased with ant abundance and richness, coffee density (a local factor), and rustic coffee within 200 m (a landscape factor). Prey removal on trees declined with vegetation complexity, but increased with abundance and richness of ants. Characteristics of the ant community were consistent predictors of prey removal, whereas local and landscape habitat features were less important, and only three habitat features correlated with prey removal. Our results demonstrate the positive effects of ant diversity for predatory function, and that promoting pest control services within coffee agroecosystems may be best accomplished by manipulating ant abundance and richness, or vegetation factors that correlate with ants.

“…Gillison et al (2004) found shade grown coffee (an agroforestry system) to have higher levels of biodiversity in comparison to sun coffee but lower when compared to secondary or primary forests. Diverse fauna and flora have been reported in various coffee systems including migratory birds such as the cerulean warbler (Setophaga cerulean) (Bakermans et al 2009), orchids (Solis-Montero et al 2005), rare bats (Estrada et al 2006), ants (Armbrecht et al 2005), other arthropods (Carlo et al 2004) and amphibians (Santos-Barrera et al 2011). …”

Tree diversity on sustainably certified and conventional coffee farms in Central America

Shade coffee agroforestry systems have the potential to support biodiversity. Sustainable certification of coffee has been promoted as a means to provide incentives to maintain these systems, but as yet there is little evidence if this is effective. We analyzed tree diversity on smallholder organic and conventional farms in buffer zones of three conservation areas in Costa Rica, Guatemala and Nicaragua (the later included some large-scale conventional and Rainforest Alliance certified farms). Organic farms had greater farm level tree species richness and Shannon diversity compared to conventional farms; estimated native tree species richness across the landscape was probably greater on organic farms than conventional in Nicaragua (48 versus 28 species respectively) and possibly in Guatemala (23 versus 15 species respectively). Organic farms had higher shade levels and more tree strata than conventional farms. In Guatemala and Nicaragua tree species composition was not closely related to whether farms were organic or conventional, although within composition clusters, organic farms tended to have greater diversity. In contrast, organic and conventional farms in Costa Rica mostly belonged to different tree species clusters. In Nicaragua most large-scale farms, and all Rainforest certified farms, formed a distinct species composition cluster with presence of old-growth forest species and within which Rainforest farms had greater diversity. Tree species composition of the shade seems to be mainly due to management history; but certification effectively differentiates those farms with greater tree diversity. Longer-term monitoring is required to determine whether certification can be an incentive to conserve or expand biodiverse coffee agroforestry systems within the buffer zones around conservation areas.

“…Different taxa vary in response to increases in tree diversity, canopy shade, and decreased agrochemical use (Moguel and Toledo 1999, Mas and Dietsch 2003, García Estrada et al 2006, Gagic et al 2012; thus, some taxa may be more sensitive to agricultural landscape changes and act as indicators of habitat simplification (e.g. Pocock andJennings 2008, De la Mora and.…”

Parasitism of ants that nest in rotting wood by eucharitid wasps was studied in order to examine whether habitat and season influence ant parasitism, vegetation complexity and agrochemical use correlate with ant parasitism, and whether specific local and landscape features of agricultural landscapes correlate with changes in ant parasitism. In a coffee landscape, 30 coffee and 10 forest sites were selected in which local management (e.g., vegetation, agrochemical use) and landscape features (e.g., distance to forest, percent of rustic coffee nearby) were characterized. Rotten logs were sampled and ant cocoons were collected from logs and cocoons were monitored for parasitoid emergence. Sixteen ant morphospecies in three ant subfamilies (Ectatomminae, Ponerinae, and Formicinae) were found. Seven ant species parasitized by two genera of Eucharitidae parasitoids (Kapala and Obeza) were reported and some ant-eucharitid associations were new. According to evaluated metrics, parasitism did not differ with habitat (forest, high-shade coffee, low-shade coffee), but did increase in the dry season for Gnamptogenys ants. Parasitism increased with vegetation complexity for Gnamptogenys and Pachycondyla and was high in sites with both high and low agrochemical use. Two landscape variables and two local factors positively correlated with parasitism for some ant genera and species. Thus, differences in vegetation complexity at the local and landscape scale and agrochemical use in coffee landscapes alter ecological interactions between parasitoids and their ant hosts.
