Effects Of Douglas-Fir Foliage Age Class On Western Spruce Budworm Oviposition Choice And Larval Performance, Kimberly A. Dodds, Karen M. Clancy, Kathryn J. Leyva, David Greenberg, Peter W. Price

Great Basin Naturalist

The western spruce budworm (Choristoneura occidentalis Freeman) prefers to feed on flushing buds and current-year needles of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco). Budworm larvae will not typically consume older age classes of needles unless all current-year foliage is depleted. We tested the following null hypotheses: (1) budworm larvae can feed on foliage with a wide range of qualities (i.e., current 1-, 2-, or 3-year-old needles) without measurable effects on fitness; and (2) budworm adults do not show any oviposition preference linked to the age of the foliage they fed on as larvae. We used both laboratory and field …

Selecting Wilderness Areas To Conserve Utah's Biological Diversity, Diane W. Davidson, William D. Newmark, Jack W. Sites Jr., Dennis K. Shiozawa, Eric A. Rickart, Kimball T. Harper, Robert B. Keiter

Great Basin Naturalist

Congress is currently evaluating the wilderness status of Bureau of Land Management (BLM) public lands in Utah. Wilderness areas play many important roles, and one critical role is the conservation of biological diversity. We propose that objectives for conserving biodiversity on BLM lands in Utah be to (1) ensure the long-term population viability of native animal and plant species, (2) maintain the critical ecological and evolutionary processes upon which these species depend, and (3) preserve the full range of communities, successional stages, and environmental gradients. To achieve these objectives, wilderness areas should be selected so as to protect large, contiguous …

Forty Years Of Rangeland Research In The Meekatharra And Wiluna Districts (1956-1996), Andrew Thomson, John Morrissey

Agriculture reports

This document is an account of the research undertaken by this Branch over the past 40 years, and it provides a general explanation of the results. It also includes descriptions of many of the Land Conservation District projects at Meekatharra and Wiluna. A number of trials and community based projects from other districts relevant to this publication have also been included as supplementary information.

Wood And Stem Anatomy Of Menispermaceae, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Qualitative and quantitative data are presented for 17 collections of 15 species representing 14 genera. One species is a shrub (Cocculus laurifolius), one a subshrub (C. trilobus), and the remainder are lianas. Successive cambia are analyzed with respect to ontogeny and histology of products. Whether any Menispermaceae may or may not plesiomorphically lack successive cambia would require a more extensive survey of the family. Apomorphic absence of successive cambia is likely for species with subshrub growth forms (Cocculus trilobus, Menispermum canadense L.). Lianoid Menispermaceae share the following features: successive cambia, wide vessels, wide rays, …

Patterns Of Dilatation Growth In Ficus Pumila And Ficus Sycomorus, Simcha Lev-Yadun

Aliso: A Journal of Systematic and Floristic Botany

Dilatation growth occurs in the secondary phloem rays, in the axial secondary phloem parenchyma, and in the parenchyma of the cortex of Ficus pumila (a Iiana) and Ficus sycomorus (a tree). Dilatation growth in Ficus pumila is mostly the result of meristematic activity, but in Ficus sycomorus it is the result of both meristematic activity and increase in cell size. Dilatation meristem is formed in the rays in various patterns: in the center of the ray, at one or two of the ray's margins, in horizontal or diagonal strips (relative to the axis) in the ray, or in more than …

Studies In Macrosiphonia (Apocynaceae): Generic Recognition Of Telosiphonia, James Henrickson

Aliso: A Journal of Systematic and Floristic Botany

Woodson recognized two subgenera within Macrosiphonia (Apocynaceae: Apocynoideae), a South American subgenus Eumacrosiphonia, and a North American subgenus Telosiphonia each with five species. Both taxa are characterized by low subshrub-shrub, nonviny growth habits, white, long-tubed, vespertine corollas of a type associated with moth pollination. Their distinctive anther and style-tip characteristics show each is related to a group of genera around Mandevilla and Mesechites. The two subgenera, however, differ strongly from each other in inflorescence, style-head structure, and pollen size indicating that they are not sister taxa and that Macrosiphonia as currently recognized is polyphyletic. Thus the subgenus Telosiphonia …

Baccharis Malibuensis (Asteraceae): A New Species From The Santa Monica Mountains, California, R. Mitchell Beauchamp, James Henrickson

Aliso: A Journal of Systematic and Floristic Botany

Baccharis malibuensis is described from the Malibu Lake region of the Santa Monica Mountains, Los Angeles County, California. It is closely related to Baccharis plummerae subsp. plummerae but differs in having narrow, subentire, typically conduplicate, sparsely villous to mostly glabrous leaves with glands occurring in depressions on the adaxial surface, more cylindrical inflorescences, and a distribution in open chaparral vegetation. The new taxon shares some characteristics with B. plummerae subsp. glabrata of northwestern San Luis Obispo County, e.g., smaller leaves, reduced vestiture, and occurrence in scrub habitat, but the two taxa appear to have developed independently from B. p. subsp. …

Population Structuring And Patterns Of Morphological Variation In Californian Styrax (Styracaceae), Peter Fritsch

Aliso: A Journal of Systematic and Floristic Botany

Recent studies of genetic variation within and among populations and phylogenetic estimates have provided evidence bearing on the evolutionary history and taxonomy of Styrax in California (S. redivivus). In this paper, data from these studies are further analyzed and integrated with new data from morphology to gain insight into the nature and taxonomic significance of character variation within this species. Six morphological characters thought to be important in the delimitation of infraspecific taxa within S. redivivus were measured on 52 herbarium specimens and analyzed with Pearson correlations and multivariate methods. Five characters are significantly associated with latitude and …

Using Confocal Microscopy In The Study Of Plant Structure And Development, Mark P. Running, Elliot M. Meyerowitz

Aliso: A Journal of Systematic and Floristic Botany

The widespread application of confocal laser scanning microscopy has revolutionized biological imaging. We have developed a protocol for using confocal microscopy to examine the development of wild type and mutant Arabidopsis thaliana, overcoming the technical difficulties associated with examining whole-mounted plant tissue. This allowed us to rapidly determine the underlying cellular defects that lead to the morphological changes visible in several mutants, and has led to a greater understanding of the mechanisms involved in the control of floral organ number.

Genetic Dissection Of The Morphological Evolution Of Maize, John Doebley

Aliso: A Journal of Systematic and Floristic Botany

Maize (Zea mays ssp. mays) and its wild progenitor, teosinte (Z. mays ssp. parviglumis) differ dramatically in inflorescence and plant architecture despite the fact that their evolutionary divergence occurred within the past 10,000 years or less. To elucidate the genetic control of the morphological differences between maize and teosinte, my colleague and I employed quantitative trait locus mapping with molecular markers. Results indicated that most of the variation in plant and inflorescence morphology between maize and teosinte can be explained by five restricted regions of the genome. In this paper, characterization of three of these regions …
