Live Oak (<em>Quercus virginiana</em>) Recruitment and Seedling Survivorship in a Southern Maritime Forest
… States. These maritime forests are dominated by oak trees, pines, and magnolias, which are essential floral components of the maritime forest ecosystem. Because of natural forces like hurricanes and plant pathogens, as well as the forestry practices of humans, these maritime forests are …

Effects of Seasonal Burns on Avian Foraging in a Central Texas Ashe Juniper-Live Oak Savanna
North American grassland birds have been declining for the past three decades. Loss of habitat from urbanization, agricultural land use, and encroachment of woody species may account for this decline. Prescribed burning is one method for restoring remnants of grassland habitat, typically performed …

Hypersensitive Response in Live Oak: Characterization and Efficacy Against a Host of Specific Gall-Forming Wasp
… in the leaves of Quercus fusiformis (plateau live oak) in response to oviposition by the host specific gall-forming wasp Belonocnema treatae to assess whether apparent HR functions in plateau live oak as a plant defense, and if so, to estimate its importance. To do this I examined the …

Herptile Abundance and Diversity in Response to Seasonal Burning on a Central Texas Ashe Juniper-Live Oak Savanna
… community of a central Texas Ashe juniper-live oak savanna. One trapping line, consisting of 1 drift fence, 2 pitfall traps and 2 funnel traps, was established on 12 treatment (6 on each burn treatment) and 6 control plots (unburned), for a total of 18 trap lines. Eighty-two individual …

Composition of the woody plant understory of plateau live oak (Quercus virginiana var fusiformis) clusters in a central Texas savanna
Plateau live oak is thought to act as a nurse plant to other woody species on the Edwards Plateau of central Texas; however, little is known of the nature, extent and duration of this facilitation. In this study, a comprehensive assessment of the composition and abundance of understory woody plants …

Reciprocal Transplant and Machine Learning Study of Oak Mistletoe on Three Host Oak Species in Santa Margarita, California
<p>At Santa Margarita Ranch, California, oak mistletoe (Phoradendron villosum) parasitizes valley oak and blue oak but cannot be found growing on coast live oak despite its abundance and ability to parasitize coast live oak in other areas. It seems as though this species of mistletoe is …

Structure of Two Cover Types of Southern Oak Woodland in California
<p>The southern oak woodland of southern California was analysed relative to the local distribution of the trees, density per acre, relative density, relative dominance, percentage of trees growing in close association to boulders, percentage of trees forked below breast height, frequencies of tree …

Plant Associations of the Edwards, Walnut, and Glen Rose Formations in Hays County, Texas
… was characterized by an association of plateau live oak, Ashe juniper, Mexican persimmon, and cedar elm, with an understory of little bluestem, cedar sedge, curly mesquite, and dropseeds. The Walnut clay was dominated by Texas oak and Ashe juniper and a poorly developed understory composed …

Parallel and Nonparallel Patterns of Genetic Co-Differentiation: Evidence for Host Associated Differentiation Among Trophic Levels of the Oak Gall Wasp System
… Cynipidae) induces galls on three species of live oak (Quercus) across the southern USA. Both HAD and geography structure genomic variation among host associated populations of B. treatae. The generalist inquiline parasitoid, Synergus sp. (Hymenoptera: Cynipidae) develops within B. treatae …

Effects of Prescribed Burning on Black-Capped Vireo Habitat, Territory Establishment, and Production
… practice has been the redevelopment of a scrub-oak woodland containing vast numbers of live oak (Quercus virginiana) and white shin oak (Quercus durandii) mottes. Annual surveys conducted on the Area since 1986 show an increasing trend in the number of Black-capped Vireo (Vireo atricapillus) …

SEASONAL FLAMMABILITY COMPARISONS OF NATIVE AND EXOTIC PLANTS IN THE POST OAK SAVANNAH, BLACKLAND PRAIRIE, AND PINEYWOODS ECOREGIONS OF TEXAS
… (<em>Juniperus virginiana</em>), and escarpment live oak (<em>Quercus fusiformis</em>); and two deciduous species: Chinese tallow (<em>Triadica sebifera</em>) and southern red oak (<em>Quercus falcata</em>). Live foliar and small diameter branch wood samples were collected in the Pineywoods, Post …

Soil Amelioration and Plant Establishment on Sodium Affected Soils on Galveston Island, Texas
… site. In addition, three species of plants, live oak (Quercus virginiana), hybrid bald cypress (Taxodium distichum), and yellow hibiscus (Hibiscus hamabo) were planted on the treatment plots. A randomized factorial design using the eight treatment combinations with the three plant species was …

Effects of Prior Defoliation on the Timing of Life Cycle Events and Susceptibility to Natural Enemies of a Host Specific Gall-Former
In short lived phytophagous insects specialized to exploit specific plant tissues, phenological synchronization between plant and insect life cycle events is crucial and likely under selection. Here I report on past (1995-2001) and recent (2006-2007) patterns of emergence phenology and survivorship …

Host Plant and Spatial Influences on the Natural Enemy Community Structure of a Host Specific Insect Herbivore
… specialization across the southern US on three live oak species, Quercus fusiformis (Qf), Quercus virginiana (Qv), and Quercus geminata (Qg). I sampled the natural enemy community at 94 sites by rearing natural enemies that emerged from galls collected at each site. I identified 32,722 natural …

Development of Urban Tree Growth Models Based on Site and Soil Characteristics
Trees provide numerous benefits crucial to urban environments, yet poor growing conditions often prevent trees from reaching their genetic potential for growth, longevity, and ecosystem function. To overcome these limitations, greater understanding of tree growth in the urban environment is needed. …
