AbstractThis study investigates the distance and patterns of pollen dispersal before and after logging in a low-density population of the dioecious, insect pollinated tree species, Bagassa guianensis, in the Brazilian Amazon. All adult trees found before and after logging in a 500 ha plot were mapped and genotyped for six microsatellite loci. Seeds collected before and after logging were also sampled and genotyped. We used a categorical paternity analysis to determine seed paternity. Our results showed similar levels of pollen flow before (23%) and after logging (26%), but an increase in the mean effective pollination neighbourhood area, and a decrease in the rate of mating among relatives after logging, resulting in open pollinated seeds with lower levels of inbreeding (0.126) than before logging (0.222). We also detected changes in the mating pattern between before and after logging, a decrease in the median pollen dispersal distance and effective number of pollen donors after logging. Our results support the idea that reproductive trees should be maintained in the plot and around logged areas, using lowest levels of logging intensity to maintain pollen flow and decrease the relatedness of subsequent generations.

Elicited imitation tasks are frequently used as a diagnostic tool in evaluating children with communication handicaps. This article presents a scoring procedure that can be used to obtain an in-depth descriptive analysis of responses produced on elicited imitation tasks. The Elicited Language Analysis Procedure makes it possible to systematically evaluate responses in terms of both their syntactic and semantic relationships to the stimulus sentences presented by the examiner. Response quality measures are also included in the analysis procedure.
