This dissertation investigated potential ecological limitations to seedling regeneration in young, seasonally dry, evergreen forest restoration plantations in northern Thailand. We explored whether recruitment of colonizing tree species in the restoration plantations can be attributed to seed dispersal mode (i.e. abiotic or animal dispersal) and seed size. We did this...
Field studies were conducted from 1996 to 1998 in three villages in a Highland watershed in Mae Hong Son Province, northern Thailand. The objectives of the study were to classify and define the fruit-based agroforestry cropping system and investigate
management activities used by villagers. In the first part of the...
The central purposes of this study were to review the
historical sources of David Kolb's formulation of experiential
learning theory, and to determine the effect and
application of Kolb's theory and Learning Style Inventory
as reflected in the literature between 1971 and 1990.
It was found that Kolb based his...
Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...
Natural selection, in its most basic form, is described as a process in which traitsincrease or decrease in frequency depending on their fitness, and only the trait withthe highest fitness will remain in the population. Yet, populations rarely have asingle `optimal' trait. The way natural selection maintains this observed variationwithin...
The objective of this work is to add to the body of translational data between high dose animal model research and the environmentally relevant human metabolism of the persistent pollutant dibenzo[def,p]chrysene (DBC). We furthered the knowledge of gene/exposure interactions by determining the carcinogenesis risk based on Cyp1b1 genotype following in...
Rainbow trout cystatin C cDNA has been isolated from
trout liver. The full-length cystatin cDNA (674 bp)
included the 5'untranslated region and the polyadenylation
signal sequence AATAAA in the 3' region. Translation of
the cDNA defines 132 amino acid residues. Comparison of
the amino acid sequence with those of family...
Improved sensitive techniques were developed for the
determination of soluble proteins in grape, juice and wine.
These techniques which permitted direct sample analysis
without prior dialysis or concentration, were used for: 1)
characterization of heat unstable proteins, 2) evaluating
the effect of bentonite fining and ultrafiltration (UF) on
the soluble...
