NEW SYNONYMY , NEW COMBINATIONS , AND NEW SPECIES OF NORTH AMERICAN PirYOPHTHORUS ( COLEOPTERA : SCOLYTIDAE ) . PART II
— New synonymies and new combinations affecting North American Pityophthorus are proposed as follows: carinifrons Blandford. incomposilus Blaiidford, and incornmodus Blandford are removed from Pi/rop/ithorus and placed in Araplus; P. boycei Swaine {=Myeloborus catulus Blackman and M. iniquus Blackman) ; P. lautus Eichhoff = P. rhois Swaine and P. natalis Blackman) ; P. californicus new name for...
متن کاملClonal dynamics in western North American aspen (Populus tremuloides).
Clonality is a common phenomenon in plants, allowing genets to persist asexually for much longer periods of time than ramets. The relative frequency of sexual vs. asexual reproduction determines long-term dominance and persistence of clonal plants at the landscape scale. One of the most familiar and valued clonal plants in North America is aspen (Populus tremuloides). Previous researchers have ...
متن کاملMolecular systematics and radiation of western North American nymphophiline gastropods.
Three mitochondrial DNA (mtDNA) markers were used to infer the phylogenetic relationships of the morphologically diverse, species rich, and poorly understood western North American aquatic gastropod genus Pyrgulopsis (Hydrobiidae: Nymphophilinae). Sequences were obtained from 62 of 124 currently recognized species of Pyrgulopsis and representatives of four related genera of North American nymph...
متن کاملPatterns of evolution in western North American Mimulus (Phrymaceae).
A well-supported phylogeny is presented from both chloroplast DNA (the trnL/F region) and two regions of nuclear rDNA (ITS [internal transcribed spacer] and ETS [external transcribed spacer]) with nearly complete sampling for Mimulus (Phrymaceae) in western North America. Three separate genera are derived from within the clade that contains all the Mimulus species in western North America. The ...
متن کاملWidespread Triploidy in Western North American Aspen (Populus tremuloides)
We document high rates of triploidy in aspen (Populus tremuloides) across the western USA (up to 69% of genets), and ask whether the incidence of triploidy across the species range corresponds with latitude, glacial history (as has been documented in other species), climate, or regional variance in clone size. Using a combination of microsatellite genotyping, flow cytometry, and cytology, we de...
