Phylogeographic inferences concerning evolution of Brazilian Passiflora actinia and P. elegans (Passifloraceae) based on ITS (nrDNA) variation.
BACKGROUND AND AIMS Passiflora actinia and P. elegans, two markedly parapatric species, have their southern and northern distribution limits, respectively, in the most southern part of the Brazilian Atlantic Rain Forest. Despite the fact that they are classified in different taxonomic series, previous phylogenetic studies of this genus revealed a high genetic similarity between them. The aim of...
متن کاملPhylogeny, biogeography and divergence times in Passiflora (Passifloraceae)
As part of a long-term investigation on the evolution of Passiflora L., we investigated the divergence ages of the genus and diversification of its subgenera, relating them with biogeographical and/or historical events, and other characteristics of this taxon. The main aim of the present work was to evaluate the biogeographic distribution of this genus to better understand its evolutionary hist...
متن کاملEfficiency of ITS Sequences for DNA Barcoding in Passiflora (Passifloraceae)
DNA barcoding is a technique for discriminating and identifying species using short, variable, and standardized DNA regions. Here, we tested for the first time the performance of plastid and nuclear regions as DNA barcodes in Passiflora. This genus is a largely variable, with more than 900 species of high ecological, commercial, and ornamental importance. We analyzed 1034 accessions of 222 spec...
متن کاملCrab spiders affect flower visitation by bees
In a field experiment, the bumblebee, B. ternarius, visited milkweed patches harboring crab spiders, Misumena atia, at a lower frequency than patches free of crab spiders, and honeybees showed a similar but non-significant trend. Two other bumblebee species, B. terricola and B. agans, did not avoid the spider patches. The latter two species are larger than B. ternarius and honeybees and suffer ...
متن کاملA structural review of foliar glands in Passiflora L. (Passifloraceae)
Extrafloral glands in Passifloraceae species have aroused the interest of many researchers because of their wide morphological diversity. The present work analyzed the foliar glands on 34 species of Passiflora from samples containing glands in the petiole and foliar blade fixed in 50% solution of formaldehyde-ethanol-acetic acid and stored in a 70% ethanol solution. For anatomical analyses, par...
