Phylogeny of Cyperaceae Based on DNA Sequence Data: Current Progress and Future Prospects
The phylogenetic position of 40 species in 21 genera is presented in this study for the first time, elucidating their position in Abildgaardieae (Trachystylis), CryptangIEae (Didymiandrum, Exochogyne), Cypereae (Androtrichum, Volkiella), Eleocharideae (Chillania), and Schoeneae (Calyptrocarya, Morelotia).
Phylogeny and Biogeography of the Carnivorous Plant Family Sarraceniaceae
A robust, species-rich phylogeny of Sarraceniaceae is presented based on seven mitochondrial, nuclear, and plastid loci that suggest climatic change at different temporal and spatial scales in part shaped the distribution and diversity of this carnivorous plant clade.
The significance of Cyperaceae as weeds.
An overview of cyperaceous weeds, including economic losses, population dynamics, control methods, identification, biology, ecology, dispersal mechanisms, spread, and discussions of major weeds of agriculture, forestry, urban areas, and natural communities are provided.
Plant DNA barcodes and species resolution in sedges (Carex, Cyperaceae)
Investigation of the species discriminatory power of a subset of the proposed plant barcoding loci in Carex suggests that a matK barcode could help with species discovery as 47% of Carex taxa recently named or resolved within cryptic complexes in the past 25 years also formed unique species clusters in upgma trees.
Phylogeny of Carex subg. Vignea (Cyperaceae) Based on Non-coding nrDNA Sequence Data
The results indicate that this inflorescence type has evolved multiple times and is derived within subg.
Amplified fragment length polymorphism analysis reveals three distinct taxa in Carex digitalis sect. Careyanae (Cyperaceae)
Unweighted pair-group (UPGMA) cluster, neighbor-joining (NJ), and parsimony analyses using amplified fragment length polymorphism (AFLP) data revealed the presence of three taxa within Carex
Making Carex monophyletic (Cyperaceae, tribe Cariceae): a new broader circumscription
Funding for the phylogeny and classification of Carex was received from the Natural Sciences and Engineering Research Council, Canada, and the National Natural Science Foundation of China.
Flesh Flies (Diptera: Sarcophagidae) Associated with North American Pitcher Plants (Sarraceniaceae), with Descriptions of Three New Species
The sarcophagid flies that breed in North American pitcher plants of the genus Sarracenia are taxonomically revised and described and life history information is provided, including host associations between the flies and pitcher plant species.
Allozyme variation and genetic relationships among species in the C arex willdenowii complex (Cyperaceae)
A taxonomic study by Naczi, Reznicek, and Ford has determined that three species can be recognized within the C. willdenowii complex, with a caespitose growth habit and perigynia in close proximity to the staminate flowers suggest adaptations for selfing and therefore low levels of heterozygosity.
Morphological, geographical, and ecological differentiation in the Carex willdenowii complex (Cyperaceae).
Field studies as well as principal components analysis and analyses of variance of specimen measurements revealed morphologic variation within Carex willdenowii correlated with differences in geographical distribution and habitat characteristics, suggesting the systematics of other common, widespread, and morphologically divergent species should be investigated.
