متن کاملPotentilla Fruticosa (rosaceae) as a Nectar Plant for Butterflies
Despite its wide distribution, little documentation exists to confirm that butterflies use the woody shrub Potentilla fruticosa (Linnaeus) (Rosaceae) as a nectar plant. During the summer of 2004, we observed 36 individual butterflies belonging to 10 species nectaring on P. fruticosa in the Jemez Mountains, New Mexico. Butterflies spent 56% of total observed nectaring time on P. fruticosa, where...
متن کاملMegagametophyte development in Potentilla nivea (Rosaceae) from northern Swedish Lapland.
An investigation of the embryology of Potentilla nivea was carried out using a confocal laser scanning microscope. The crassinucellate nature of the ovule as well as the presence of a multicellular archesporium was confirmed. A "nucellar cap" builds up as the result of mitotic divisions in the parietal cell tissue and the nucellar epidermis. Earlier reports that several mature megagametophytes ...
متن کاملProspects and limits of the flow cytometric seed screen – insights from Potentilla sensu lato (Potentilleae, Rosaceae)
The flow cytometric seed screen allows for identification of reproductive modes of seed formation and inference of the ploidy of contributing gametes. However, the lack of a mathematical formalization to infer male/female genomic contributions, and the prerequisite of a binucleate female contribution to the endosperm limits its applicability. We evaluated this assumption combining a DNA-based p...
متن کاملMolecular data and ploidal levels indicate several putative allopolyploidization events in the genus Potentilla (Rosaceae)
Several naturally occurring hybrids in Potentilla (Rosaceae) have been reported, but no molecular evidence has so far been available to test these hypotheses of hybridization. We have compared a nuclear and a chloroplast gene tree to identify topological incongruences that may indicate hybridization events in the genus. Furthermore, the monophyly and phylogenetic position of the proposed segreg...
