Abstract: In the Parana basin, the Serra de Maracaju juxtaposes the Seasonal Dry Forest and the cerradão (a phytophysiognomy of Cerrado), two distinct vegetation types that differ in canopy height, tree density, and com- position of the understory. In the same way, these differences may be reflected in the composition of climbing plant species found in these two forest types. Thus, in this study we compared the climbing species in two forest fragments of Serra de Maracaju to understand: (1) Are species richness and floristic composition of climbing plants similar in cerradão and seasonal deciduous forest?, (2) What degree of floristic compositional differ- ence exists between the two vegetation types?, (3) Do the two vegetation types differ significantly in climbing mechanisms, life forms, and dispersal syndromes represented among climbing species? For this, we established and sampled four plots per forest type over 24 months. Species were identified and each one classified, based on three discrete traits. Proportional differences were analyzed using chi-square tests. Our results showed that spe- cies richness and floristic composition of climbing plants in the cerradão and the seasonal deciduous forest were not similar. Climber species richness in cerradão was 37 while in the seasonal deciduous forest it was 31; they share only 13 species. Four families, Dioscoreaceae, Fabaceae, Malpighiaceae, and Sapindaceae, included over 60 % of the climbing species. The morphological traits most common in both forest types were herbaceous life form, apical twining mechanism, and wind dispersal. Dioscoreaceae was found to be the dominant family, but is the first time to be reported for this condition in Brazil. Bignoniaceae and Passifloraceae ocurred only in the cerradão, and Asteraceae and Combretaceae in the seasonal deciduous forest; some species were found exclu- sively in a type of forest. Floristic composition of the cerradão and seasonal deciduous forest fragments were substantially different, in spite of physical proximity. However, their climbing species are not statistically dis- tinct in morphological characteristics, possibly due to uniform climatic conditions and the similarity of species because of a shared ancestry (similar families).

    A Multigene Approach for Investigating DNA Barcode Lineages in Provisional Cryptic Species of Lepidoptera in Costa Rica

    A multigene approach for investigating DNA Barcode lineages in provisional cryptic species of Lepidoptera in Costa Rica by Claudia Bertrand A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Integrative Biology Guelph, Ontario, Canada © Claudia Bertrand, March, 2012 ABSTRACT A multigene approach for investigating DNA barcode lineages in provisional cryptic species of Lepidoptera in Costa Rica Claudia Bertrand Advisor: University of Guelph, 2012 Professor M. Hajibabaei DNA barcoding has illuminated genetically distinct lineages within what appears to be one morphological species. For example, a large-scale DNA barcode analysis of Lepidoptera in the Área de Conservación Guanacaste has revealed that 8% of the morphospecies show more than one DNA barcode lineage. To assess the evolutionary significance of five of these lineages I conducted further molecular analyses by sequencing mitochondrial cytochrome b, nuclear Elongation Factor 1 subunit α and ribosomal Internal Transcribed Spacer 2, and compare their gene genealogies with the provisional species tree hypothesized by DNA barcode genetic distances. Both mitochondrial and nuclear markers support the existence of three species in Urbanus belli. The lack of corroboration between markers in the four remaining species either suggests that the chosen nuclear markers have not diverged since speciation, or there has been recent hybridization between lineages. In the case of Eacles imperialis, hybridization is strongly suggested.
