Shade coffee farms promote genetic diversity of native trees
when caterpillars fed on fruit-bearing pepper plants. Here, although initially feeding on leaves, the beet armyworms soon moved into the maturing fruits (Figure 1C). Our results indicate that visiting honeybees provide plants with a totally unexpected advantage: bees flying around plants inhibit the feeding intensity of herbivorous caterpillars, resulting in a clear reduction of leaf damage. Th...
متن کاملPest reduction services by birds in shade and sun coffee in Jamaica
The reduction of insect pests by birds in agriculture may provide an incentive for farming practices that enhance the conservation value of farms for birds and other wildlife. We investigated pest reduction services by insectivorous birds on a coffee farm in Jamaica, West Indies. Our results suggest that birds reduced insect pests on our study site. Infestation by the coffee berry borer Hypothe...
متن کاملEffects of Shade-Tree Species and Crop Structure on the Winter Arthropod and Bird Communities in a Jamaican Shade Coffee Plantation1
I examined the effects of two farm management variables, shade-tree species and crop structure, on the winter (dry season) arthropod and bird communities in a Jamaican shade coffee plantation. Birds and canopy arthropods were more abundant in areas of the plantation shaded by the tree Inga vera than by Pseudalbizia berteroana. The abundance of arthropods (potential pests) on the coffee crop, ho...
متن کاملActivity in Sun and Shade Plants1
The consequences of light adaptation and acclimation of photosynthesis on photosynthetic nitrogen use efficiency (NUE), particularly as it relates to the efficiency of ribulose-1,5-bisphosphate carboxylase (Rubisco) use in photosynthetic CO2 assimilation, was studied in the sun species Glycine max and the shade species Alocasia macrorrhiza. Both G. max and A. macrorrhiza were found to possess t...
متن کاملEffects of land use on bird populations and pest control services on coffee farms.
Global increases in both agriculture and biodiversity awareness raise a key question: Should cropland and biodiversity habitat be separated, or integrated in mixed land uses? Ecosystem services by wildlife make this question more complex. For example, birds benefit agriculture by preying on pest insects, but other habitat is needed to maintain the birds. Resulting land use questions include wha...
