Litter Production And Nutrient Content Of Litter In The Seasonally Flooded Dismal Swamp, Marta M. Gomez

Biological Sciences Theses & Dissertations

Litter production was studied in four plant communities in the Great Dismal Swamp, Virginia, that differ primarily in species composition and flooding regime. Greatest leaf deposition occurred in the more flooded communities, maple-gum (Acer-Nyssa) with 536 g m^-2 yr^-1 and cypress (Taxodium distichum (L.) Richard) with 528 g m^-2 yr^-1, followed by the cedar (Chamaecyparis thyoides (L.) BSP) and mixed hardwood (Quercus-Acer-Nyssa-Liquidambar) communities with 506 g m^-2 yr^-1 and 455 g m^-2 yr^-1, respectively. Litter nutrient concentrations were generally higher in the cypress and maple-gum stands, indicating greater nutrient availability …

Chlorophyll Fluorescence Probe Of Ultraviolet-B Photoinhibition Of Primary Photoreactions In Intact Leaves, Robert S. Nowak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Damage to primary photosynthetic reactions caused by environmental stress can be assessed by measurement of chlorophyll fluorescence induction in intact leaves. This approach was applied in studies of ultraviolet-B photoinhibition of photosynthesis in Pisum sativum L. and Rumex patientia L. leaves. At ultraviolet-B dose rates insufficient to cause inhibition of net photosynthesis, changes in the magnitude of fluorescence transients did occur, which suggested direct effects on chloroplast pigments in Pisum and inhibition of photosynthetic electron transport between the photosystems in both species. Leaves of these two species subjected to a much higher dose rate had a significant reduction of net …

Effects Of Host Plant Patch Size And Surrounding Plant Type On Insect Population Dynamics, Lynn A. Maguire

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the present study was to investigate how plant spatial patterns and insect behavior interact to influence the population dynamics of insects using the plants. The study included three phases: l) field experiments using collards (Brassica oleracea) and the crucifer insect fauna; 2) simulation models representing the population dynamics of an insect herbivore as functions of insect dispersal behavior and host plant patch size; and 3) model-field syntheses integrating model predictions and field variability estimates to choose an appropriate spatial scale for future field experiments or applications.

In field experiments on surrounding plant type, collards were …

Report No 40 - Commercially Exploited Vacsular Plants Native In Western Australia: Census, Atlas And Preliminary Assessment Of Conservation Status, Barbara L. Rye, S. D. Hopper, L. E. Watson

Fisheries Research Reports

A census and atlas is provided of 1 119 native Western Australian plant species which were commercially exploited during 1977-79 in the cut plant, nursery or seed trades. The exploited species are concentrated in the vicinities of Perth and Albany, the two matin centres for the wildflower industry. Preliminary assessments of the conservation status of the exploited species are provided. Approximately r200 species are regarded as being rare, geographically or poorly collected, and further studies are recommended for these species to determine whether they are in danger of overexploitation.

Fisheries Report No 39 - The Wildlife Of The Proposed Toolonga Nature Reserve, Shark Bay Shire, Western Australia, A. A. Burbidge, P. J. Fuller, K. Cashin

Fisheries Research Reports

Following a Cabinet endorsed recommendation by the Environmental Protection Authority in 1975, an area of vacant Crown Zand (the Toolonga Area) was examined during April and September, 1978.

The geology, soils and vegetation of the area are described and annotated lists of mammals, birds, amphibians and reptiles are presented. A small part of the area lies in the South West Botanical Province (Irwin District) but most is in the Eremaean Botanical Province (Carnarvon District). The vertebrate fauna is a mixture of south-western, Shark Bay and arid zone species, but the last predominate.

The Toolonga Area provides an opportunity to protect …

Effect of stubble and seed infection on S. nodorum at Badgingarra. Fungicide timing on Septoria control.

Double cropping wheat was simulated by spreading stubble fragments collected from an adjoining paddock at 30 g/m2. Infected seed was from a 1979 sowing at Badgingarra, clean seed was pedigree Gamenya ex Merredin. Treatments were thus:- 1. Clean seed, no stubble. 2. Clean seed plus stubble. 3. Infected seed, no stubble. 4. Infected seed plus stubble. Plots were 10 x 25 m separated by equal sized barley buffers.
