A New Species Of Cyperus Section Incurvi (Cyperaceae) From Venezuela, Gordon Tucker

Faculty Research & Creative Activity

Cyperus fedoniae is described as a new species. It is known from a single collection from the lowlands of southern Venezuela. It is a member of section Incurvi. It is related to C. dichromeniformis and C. inops, from which it can be distinguished by its smaller size and features of spikelets and achenes. A distinctive feature is the arching culms which take root at the base of the spikelets.Cyperus fedoniae es descrito como una nueva especie. Se conoce de una sola muestra de las tierras bajas del sur de Venezuela. Es un miembro de la secci.n Incurvi. Est. relacionada con …

Statistical Hybrid Detection And The Inference Of Ancestral Distribution Areas In Tolpis (Asteraceae), Michael Gruenstaeudl, Bryan C. Carstens, Arnoldo Santos-Guerra, Robert K. Jansen

Biological Sciences Faculty Publications

Many historical biogeographic studies do not account for the effect of hybrid taxa on phylogenetic tree inference, despite recent advances in the statistical identification of such taxa. This investigation aims to illustrate the impact that hybrid taxa can have on ancestral area reconstructions of the plant genus Tolpis, which displays an evolutionary history possibly indicative of a back-colonization of the continental Mediterranean. We evaluate and apply two statistical hybrid detection methods, JML and STEM-hy, which assist in identifying reticulate patterns of allele coalescence. We also evaluate and apply a software tool, P2C2M, to test the fit of genetic loci to …

Vestured Pits In Echium (Boraginaceae): Island Woodiness Revisited, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Vestured pits are present on pits of secondary xylem vessels of all studied Echium species, roots as well as stems. Variations in vesturing presence do occur in the genus (across wide circular pit cavities; along margins of elliptical pit apertures; aggregated to various degrees; variously abundant), but these are difficult to define precisely and are related primarily to organography and ecology rather than to the taxonomic system. The Macaronesian species have been reported to form a single clade. Wood anatomical features other than vesturing are also closely keyed to species ecology and, in particular subclades, growth forms. Woodiness, exemplified by …

Community Structure And Demography In A Saline Pan-Dune Mosaic In The Western Mojave Desert, M. Rasoul Sharifi, William N. Brostoff, Philip W. Rundel

Aliso: A Journal of Systematic and Floristic Botany

A unique saline ecological system formed by an extensive mosaic of small clay pans and low stable dunes exists within Edwards Air Force Base in the western Mojave Desert of California. This ecosystem lies between the large Rosamond and Rogers dry lakes on the old Pleistocene lakebed of Lake Thompson. Plant communities on the low and relatively stable dunes were broadly classed as saltbush scrub, with a total canopy cover of 30–36%. Atriplex confertifolia was the typical dominant, with Ericameria nauseosa as an important associate. Taller dunes of younger age and less saline soils had similar plant cover, but a …

Richness And Current Status Of Gymnosperm Communities In Aguascalientes, Mexico, María Elena Siqueiros-Delgado, Rebecca S. Miguel, José A. Rodríguez-Avalos, Julio Martínez-Ramírez, José C. Sierra-Muñoz

Aliso: A Journal of Systematic and Floristic Botany

The gymnosperm diversity of Aguascalientes, Mexico, is presented. Fifteen species from five genera and three families are reported, two of Coniferales (Cupressaceae and Pinaceae) and one of Gnetales (Ephedraceae). Pinus is the most diverse and abundant genus with seven species. The most abundant species is P. teocote, while P. strobiformis is the scarcest. Juniperus is the next most diverse genus, represented by four species, with J. deppeana the most abundant and J. durangensis the scarcest. Cupressus lusitanica, Taxodium mucronatum and Ephedra compacta are each the sole representatives of their genera. Most conifers occupy the mountainous part of the …

Impact Of Ground Water Depletion On The Mesquite Community At Edwards Air Force Base, Western Mojave Desert, California, Jonathan E. Campbell, M. Rasoul Sharifi, Philip W. Rundel

Aliso: A Journal of Systematic and Floristic Botany

Edwards Air Force Base (EAFB) provides a habitat refugium for mesquite woodlands in the western Mojave Desert of the Antelope Valley. Although many mesquite communities in the arid southwest are considered invasive as they reduce the extent of grazing lands, the community at EAFB is composed primarily of large, widely spaced trees that provide food and shelter for local wildlife species and recreational opportunities for base personnel. Unfortunately, the range of these mesquite trees appears to be contracting as mature and old individuals dominate the community. Although anecdotal evidence suggests that the fall in the local groundwater table is responsible …
