Ant Gardeners and that Morning Cup of Java

Coffee is traditionally cultivated below a very diverse and dense shade canopy that often resembles native forest. However, worldwide coffee production has been intensified from traditional diverse farms into a number of different types of systems. At the most extreme are sun coffee plantations with few or no shade trees. The intensification of coffee plantation has led to losses of mammal, bird, and arthropod species. Intensification may also be linked to the failure of important ecosystem services.

Scientists at the Smithsonian Migratory Bird Center (SMBC) have long advocated the return to traditional shade-grown coffee for its importance as a habitat for migratory birds. In continuing studies of coffee ecosystems, they have found another benefit of retaining the natural forest system--ants. Extremely diverse and abundant predators in tropical ecosystems, ants are better able to perform services in shaded systems.

SMBC researcher Stacy Philpott, Inge Armbrecht (Universidad del Valle, Cali, Colombia) and Ivette Perfecto (University of Michigan) sampled ants in Costa Rica, Mexico, and Colombia to determine how intensification affects ant diversity. They found that ant richness declines with coffee intensification. Ant assemblages in sun coffee systems and other intensive coffee systems shared many fewer species with forests that traditional coffee farms. Species similarity also declined with coffee intensification. These were the result of three possible mechanisms: changes in the microclimatic conditions, loss of available nesting sites and lower quality nesting sites.

They then examined the functional importance of ants by looking at their relationship with the coffee berry borer, one of the more important coffee pests. The borers burrow into coffee fruits where they damage the coffee berries (seeds). More than 20 species of ants prey on the coffee berry in both shaded and sun plantations in Colombia. Ants also removed borers directly from coffee fruits and free-living borers from traps in both types of coffee plantations. Data indicated that they performed this service more in shade coffee systems. In addition, ants have a mutualistic or beneficial relationship with scale insects, which can be a pest in intensive coffee farms. Finally, when ants were absent from plants for 8 months, there was a higher incidence of two fungal diseases, coffee leaf rust and coffee leaf spot. Thus, ants are important in removing both insect pests and controlling fungal diseases in coffee ecosystems. Ants function better in the shaded plantations compared to the sun plantations.

Emerging Threats to Tropical Forests

The new book, Emerging Threats to Tropical Forests, edited by Smithsonian Tropical Research Institute scientist William Laurance and by Carlos Peres (University of East Anglia, UK), reveals the remarkably diverse panoply of perils to tropical forests and their biota, but with particular emphasis on emerging threats. These fall into four main categories:

  • threats that have only recently appeared, such as the virulent chytrid-fungus pathogen that is decimating rainforest amphibians throughout the tropical world;
  • threats that are growing rapidly in importance, such as destructive surface fires in tropical forests;
  • threats that are poorly understood, such as global warming and other climatic and atmospheric alterations;
  • environmental synergisms, whereby two or more simultaneous threats--such as habitat fragmentation and wildfires, or logging and hunting--can dramatically increase local extinctions of tropical species.

A key theme of the book is that many emerging threats to tropical forests are insidious, altering critical aspects of ecosystem functioning and biota, but in ways that can easily escape our attention because they are obscured from satellite imagery and aerial photos, or become apparent only after exhaustive, long-term field studies.

This timely and compelling book is intended for researchers, students, and conservation practitioners--for anyone interested in the fate of the world's direly threatened tropical ecosystems.
