Camptotheca Lowreyana, A New Species Of Anti-Cancer Happytrees, Shiyou Li

NCPC Publications and Patents

Camptotheca Decaisne (happytrees or Xi Shu, Nyssaceae) is a .monotypic genus endemic to China. Its single species C. acuminata Decaisne ( 1873) has been the major source of Camptothecins, the promising anti - cancer and potential anti - viral drugs (Li and Adair 1994) .

The phenotypic analysis of the genus showed that (1) C. yunnanensis Dode (1908) should be treated as a species separated from C. acuminata (see Li, n. d.) and (2) a new species as the third species of the genus should be established. The present paper describes the new species as C. lowreyana. C. lowreyana has …

Estimating Crown Height For Unthinned Planted Pines In East Texas, Young Jin Lee, J. David Lenhart

Faculty Publications

Stand-level models were derived to predict crown height or the distance from ground to the first live branch of unthinned planted loblolly (Pinus taeda L.) and slash (Pinus elliottii Eng elm.) pine trees in East Texas. Average height of the tallest trees was the principal predictor in the models. In addition, the influence of number of planted trees per acre, nonplanted basal area and fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f.sp. fusiforme ) was considered. The models quantify the plantation ages when the butt log and successive lower stem logs are clear of live branches. This information may …

Stand Conditions And Tree Characteristics Affect Quality Of Longleaf Pine For Red-Cockaded Woodpecker Cavity Trees, W. G. Ross, David Kulhavy, Richard N. Conner

Faculty Publications

We measured resin flow of longleaf (Pirzus palustris Mill.) pines in red-cockaded woodpecker (Picoides borealis Vieillot) clusters in the Angelina National Forest in Texas, and the Apalachicola National Forest in Florida. Sample trees were categorized as active cavity trees, inactive cavity trees and control trees. Sample trees were further categorized by stand position as either edge or interior trees. Longleaf cavity trees in Texas and Florida had similar resin flow characteristics. Active cavity trees on forest edges had the highest resin flow, whereas active cavity trees in forest interiors had the lowest. Trees experiencing both low and high levels of …

Linear correlation coefficients between Landsat Thematic Mapper thermal infrared data acquired on July 8, 1990 and the mean maximum daily forest ecosystem ambient air temperature recorded for sixteen systematically selected dates during June and July, 1994 were significant at the one percent level for all sixteen dates tested and ranged from 0.81 to 0.94.

The Red-Cockaded Woodpecker's Role In The Southern Pine Ecosystem, Population Trends And Relationships With Southern Pine Beetles, Richard N. Conner, D. Craig Rudolph, Daniel Saenz, Robert N. Coulson

Faculty Publications

This study reviews the overall ecological role of the Red-cockaded Woodpecker (Picoides borealis)in the southern pine ecosystem. It is the only North American woodpecker species to become well adapted to a landscape that was relatively devoid of the substrate typically used by woodpeckers for cavity excavation (i.e. snags and decayed, living hardwoods). Its adaptation to use living pines for cavity excavation has expanded the use of this fire-disclimax ecosystem for numerous other cavity-using species. As such, the Red-cockaded Woodpecker represents an important keystone species of fire-disclimax pine ecosystems of the South. Historically, populations of this woodpecker and other cavity dependent …

Species Using Red-Cockaded Woodpecker Cavities In Eastern Texas, Richard N. Conner, D. Craig Rudolph, Daniel Saenz, Richard R. Schaefer

Faculty Publications

Because of its ability to excavate cavities in living pines, the Red-cockaded Woodpecker (Picoides borealis) is a keystone species in the fire-disclimax, pine ecosystems of the southeastern United States. Many species representing multiple taxonomic classes are dependent on this woodpecker species for the cavities it creates. We examined the occupants of Red-cockaded Woodpecker cavities during spring, late summer, and winter. Cavities enlarged by other species of woodpeckers and unenlarged cavities were examined in two habitat conditions: loblolly (Pinus taeda) -shortleaf (P. echinata) pine and longleaf pine (P. palustris) habitats. Red-cockaded Woodpecker cavities provided cavity habitat for seven species of birds, …

Pulpwood Vs. Sawtimber: A “Quick And Dirty” Economic Analysis Of Hardwood Timber Management, Andy Ezell, Steven H. Bullard

Faculty Publications

A major decision in hardwood forest management is the type of final products to produce. Until recently, the only options in many areas of the South for hardwoods were sawtimber products-crossties, dimension lumber, and veneer, for example. In the past ten years, however, hardwood markets have changed dramatically. Across much of the South, hardwood pulpwood is now in very high demand.

Eyespray Vaccination: Infectivity And Development Of Immunity To Eimeria Acervulina And Eimeria Tenella, H. David Chapman, Tim E. Cherry

Faculty Publications

The infectivity of a coccidiosis vaccine and its ability to immunize chickens against two species of Eimeria was examined. The vaccine was administered to newly-hatched chicks by spraying directly onto the eye. The method resulted in a high proportion of chicks infected with E. acervulina and E. tenella. Vaccinated birds reared in cages in the absence of reinfection did not develop immunity to either species by 4 wk of age, but birds reared in floor pens developed immunity to both E. acervulina and E. tenella.

Conidial Germination And Infection By Diplocarpon Rosae On Susceptible And Resistant Rose Species, Robert J. Wiggers, J. G. West, Josephine Taylor

Faculty Publications

Conidial germination and infection by Dipplocarpon rosae, the causal organism of rose blackspot, were examined on two resistant species of roses, Rosa roxburghii and R. wichuraiana and two susceptible hybrid tea roses (R. hybrid cv. Chicago Peace and Garden Party). Fungal conidia germinated and gave rise to subcuticular mycelium that formed haustoria within epidermal cells of all four roses tested. On the resistant rose species, epidermal cells associated with the infection site became necrotic, indicating that a hypersensitive response is involved in conferring their resistance D. rosae.

Sodium Nitrite Alone Protects The Brain O _I_ Microsomal Ca -Atpase Against Potassium Cyanide-Induced Neurotoxicity In Rats, Odutayo O. Odunuge, G.. A. Adenuga

Faculty Publications

The effect of a short-term oral administration of potassium cyanide (KCN) (200 ppm in diet) with or without sodium nitrite (NaNO2) pretreatment on rat brain microsomal Ca2* ATPase was investigated. The specific activity value of the enzyme significantly decreased (p<0.05) by 50% compared with control and by 63% for KCN-treated rats compared with KCN-treated rats pretreated with NaNO;,. There was no significant difference at the h = 0.05 level between the values obtained for the control and KCN-treated rats pretreated with NaNO,. These results show both that feeding lowers brain microsomal Ca2f-ATPase activity and that NaNO, has a protective role (antidote function) in that respect.
