Pioneer tree species exhibit particular life histories and population structures that are mainly affected by the
patchy dynamics of the tropical forests. These characteristics and ecological processes, as well as other factors
such as the level of human disturbance and the distance among populations, have significant consequences on
their genetic structure and evolution, however this is still poorly understood. We developed and optimized twelve
microsatellite markers from an enriched genomic library to study the genetic diversity and structure of the pioneer
tree Croton floribundus Spreng. (Euphorbiaceae). Microsatellite loci were screened for 23 plants (juveniles) found in
two large gaps of a Semideciduous Tropical Forest in Brazil. These loci are important tools for understanding the
genetic aspects of the pioneer tree species and therefore, the successional processes and the human disturbance
effects in the tropical forests.
