Ant assemblage on a coffee farm: spatial mosaic versus shifting patchworkIvette Perfecto
School of Natural Resources and Environment, University of Michigan, Ann Arbor, MI 48109, USA
Environ Entomol 42:38-48. 2013....
Discovery dominance tradeoff: the case of Pheidole subarmata and Solenopsis geminata (Hymenoptera: Formicidae) in neotropical pasturesIvette Perfecto
School of Natural Resources and Environment, University of Michigan, Ann Arbor, MI 48109, USA
Environ Entomol 40:999-1006. 2011..geminata. In an environment with mixed resources (large and small), these two species can co-exist. We discuss the implication of this for the invasion potential of S. geminata...
The agroecological matrix as alternative to the land-sparing/agriculture intensification modelIvette Perfecto
School of Natural Resources and Environment, University of Michigan, Ann Arbor, MI 48109, USA
Proc Natl Acad Sci U S A 107:5786-91. 2010..A model that incorporates the agricultural matrix as an integral component of conservation programs is proposed. Furthermore, we suggest that this model will be most successful within a framework of small-scale agroecological production...
Biodiversity conservation in tropical agroecosystems: a new conservation paradigmIvette Perfecto
School of Natural Resources and Environment, Dana Building, University of Michigan, Ann Arbor, MI 48109, USA
Ann N Y Acad Sci 1134:173-200. 2008....
Spatial pattern and ecological process in the coffee agroforestry systemIvette Perfecto
School of Natural Resources and Environment, University of Michigan, Ann Arbor, Michigan 48109, USA
Ecology 89:915-20. 2008....
Clusters of ant colonies and robust criticality in a tropical agroecosystemJohn Vandermeer
Department of Ecology and Evolutionary Biology, Kraus Natural Science Building, University of Michigan, Ann Arbor, Michigan 48109, USA
Nature 451:457-9. 2008..Furthermore, because the species is a keystone of a larger network that contributes to the ecosystem function of pest control, this is an example of how spatial dynamics at a large scale can affect ecosystem service at a local level...
Bats limit insects in a neotropical agroforestry systemKimberly Williams-Guillén
School of Natural Resources and Environment, University of Michigan, Ann Arbor, MI 48109, USA
Science 320:70. 2008..In the wet season, bats reduced arthropods by 84%, whereas birds reduced them by only 58%. We conclude that previous "bird" exclosure experiments may have systematically underestimated the effects of bats...
Cheating on a mutualism: indirect benefits of ant attendance to a coccidophagous coccinellidHeidi Liere
Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA
Environ Entomol 37:143-9. 2008..orbigera. This is the first time that this kind of indirect positive effect is reported for an ant and a coccidophagous coccinellid. Furthermore, this indirect positive effect may be key to the persistence of A. orbigera's populations...
Ensemble composition and activity levels of insectivorous bats in response to management intensification in coffee agroforestry systemsKimberly Williams-Guillén
University of Michigan, School of Natural Resources and Environment, Ann Arbor, Michigan, United States of America
PLoS ONE 6:e16502. 2011..We conclude that diverse shade coffee plantations in our study area serve as valuable foraging and commuting habitat for aerial insectivorous bats, and several species also commute through or forage in low shade coffee monocultures...
Behavioral diversity of predatory arboreal ants in coffee agroecosystemsStacy M Philpott
Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA
Environ Entomol 37:181-91. 2008..We discuss the implications of these differences in ant behaviors for enhancement of predatory function in light of both multipredator effects and in terms of the potential importance of predator diversity...
A keystone mutualism drives pattern in a power functionJohn Vandermeer
Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA
Science 311:1000-2. 2006..We offer a biological explanation for both adherence to the power functions and associated deviations, along with supporting evidence...
Enigmatic biodiversity correlations: ant diversity responds to diverse resourcesInge Armbrecht
School of Natural Resources and Environment, University of Michigan, 430 East University, Ann Arbor, MI 48109, USA
Science 304:284-6. 2004..The specific tree species from which the twigs were derived did not explain the pattern. It appears that diversity per se at one level (twigs) creates conditions that promote diversity at another level (nesting ants)...
The agricultural matrix and a future paradigm for conservationJohn Vandermeer
Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA
Conserv Biol 21:274-7. 2007
Impacts of major predators on tropical agroforest arthropods: comparisons within and across taxaStacy M Philpott
Department of Ecology and Evolutionary Biology, University of Michigan, 830 N University, Ann Arbor, MI 48109, USA
Oecologia 140:140-9. 2004..Our results show that aggregating taxonomically related and unrelated predators into trophic levels without prior experimental data quantifying the sign and strengths of effects may lead to a misrepresentation of food web interactions...
Agroforests as model systems for tropical ecologyRussell Greenberg
Smithsonian Migratory Bird Center, USA
Ecology 89:913-4. 2008
Species loss and aboveground carbon storage in a tropical forestDaniel E Bunker
Department of Ecology, Evolution, and Environmental Biology, Columbia University, New York, NY 10027, USA
Science 310:1029-31. 2005..These results indicate that future carbon storage in tropical forests will be influenced strongly by future species composition...
