A Vascular Flora Of The Kiavah Wilderness, Scodie Mountains, Kern County, California, Erika M. Gardner
A Vascular Flora Of The Kiavah Wilderness, Scodie Mountains, Kern County, California, Erika M. Gardner
Aliso: A Journal of Systematic and Floristic Botany
Congress designated the Kiavah Wilderness in 1994 under the California Desert Protection Act. It is located in the Scodie Mountains in Kern County, ca. 24 km (15 mi) east of Lake Isabella and 24 km (15 mi) west of Ridgecrest, and encompasses a total of 137 mi2 (354 km2) with elevations ranging from 1000 to 2200 m (3500–7294 ft). The Wilderness is ecologically important because it occurs in a transition zone between two floristic provinces, the Sierra Nevada of the California Floristic Province and the Mojave Desert of the Desert Province. It is of cultural significance because …
Phylogenetics Of The Borage Family: Delimiting Boraginales And Assessing Closest Relatives, Kristen E. Hasenstab-Lehman
Phylogenetics Of The Borage Family: Delimiting Boraginales And Assessing Closest Relatives, Kristen E. Hasenstab-Lehman
Aliso: A Journal of Systematic and Floristic Botany
The placement of Boraginales, and relationships within the family have remained elusive in modern, broad phylogenetic studies. In order to assess the phylogeny of Boraginales, and specifically to test the sister lineage of the order, a data matrix of the chloroplast markers rbcL, ndhF, and trnL-trnF was assembled from GenBank and de novo sequences (representing 132 new GenBank accessions). Phylogenies inferred using Maximum Likelihood and Bayesian frameworks resulted in identical topologies. Tests for alternative topologies were used to assess whether any of the candidates for sister (Solanales, Gentianales, Lamiales, or Vahlia) to Boraginales could …
Vestured Pits In Echium (Boraginaceae): Island Woodiness Revisited, Sherwin Carlquist
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 …
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
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 …
The Vegetation And Flora Of Edwards Air Force Base, Western Mojave Desert, California, David Charlton, Philip W. Rundel
The Vegetation And Flora Of Edwards Air Force Base, Western Mojave Desert, California, David Charlton, Philip W. Rundel
Aliso: A Journal of Systematic and Floristic Botany
Edwards Air Force Base extends over 121,000 ha in the Antelope Valley of the western Mojave Desert, with much of the area part of a closed endorheic basin that held the Pleistocene Lake Thompson. Notable topographic features are Rogers, Rosamond and Buckhorn dry lakes, while rounded domes and scattered hills are present to the north and east. Elevation gradients are limited, ranging from a low of 690 m to 1044 m near the eastern margin. Diverse communities of saltbush scrub dominate the lower plains, while creosote bush scrub and Joshua tree woodlands are present away from the old lake basin. …
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
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 …
Plant Phenology And Water Relations In A Saline Pan-Dune Mosaic In The Western Mojave Desert, M. Rasoul Sharifi, William N. Brostoff, Philip W. Rundel
Plant Phenology And Water Relations 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
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 pan-dune ecosystem, positioned between the large Rosamond and Rogers dry lakes on the old Pleistocene lakebed of Lake Thompson, provides an opportunity to study the seasonal patterns in growth and flowering phenology and water relations in a saltbush scrub community dominated by a mix of C3 and C4 species. C3 shrubs initiated vegetative growth in February, with current shoot and leaf production largely ceasing in most species by mid-April. The deeply rooted …

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