The keystone species concept has contributed greatly to our thinking about how communities are structured and to our approaches to the development of conservation strategies. While keystone species have been proposed for tropical rain forest systems, the extraordinary diversity and complexity of these systems suggests that their potential for harboring keystones will be small. In this chapter we ask...
Stun guns or electromuscular incapacitation devices (EMIs) generate between 25,000 and 250,000 V and can be discharged continuously for as long as 5 to 10 min. In the United States, over 200,000 individuals have been exposed to discharges from the most common type of device used. EMI devices are being used increasingly despite a lack of objective laboratory data describing the physiological effects...
The process of seed dispersal has a profound effect on vegetation structure and diversity in tropical forests. However, our understanding of the process and our ability to predict its outcomes at a community scale are limited by the frequently large number of interactions associated with it. Here, we outline an approach to dealing with this complexity that reduces the number of unique interactions...
