Mangroves provide numerous ecosystem services, including biodiversity values such as nesting sites for piscivorous waterbirds. High concentrations of pisicivoirous birds are hypothesized to affect ecosystem dynamics, yet few studies have examined their effects in mangroves. We examined the effects of nutrient enrichment by colonial waterbirds at a mangrove rookery in...
Pelargonidin 3-glucoside (pgd 3-glu), pelargonidin 3-sophoroside (pgd 3-soph),
and pelargonidin 3-sophoroside 5-glucoside acylated with cinnamic and malonic acids
(acyl-pgd 3-soph 5-glu) were extracted from strawberries (Fragaria anannassa cv,
Totem), nasturtium flowers (Tropaeolum majus), and radish peel (Raphanus sativus L.
cv, fuego), respectively. Their stability was studied in natural and model...
A primary goal of population genetics is to identify the role of
microevolutionary forces in producing observed patterns of molecular and phenotypic
variation. I conducted four studies in the northern leopard frog, Rana pipiens, to
determine just how mutation, migration, genetic drift, and selection influenced,
genetic structure of mitochondrial DNA...
It has been suggested that cellular damage from oxygen radicals is one of the processes leading to cardio-vascular disease and cancer. Natural antioxidants prevent uncontrolled oxidative reactions by decreasing molecular oxygen levels, scavenging chain-initiating and chain-propagating free radicals, chelating metals, or decomposing peroxides. Beer is rich in antioxidants, derived both...
A behavioral study on fishery participation and fishing location choice for the West Coast Salmon fishermen was undertaken to determine the effect of salmon fishery closures on the distribution of fishermen across alternative fisheries and fishing locations. A dataset describing fishing trips from West Coast salmon vessels from 2005 to...
The role of science in marine policy, and environmental policy in general, is a debated topic. Currently, there is an increasing desire for transparent and participatory democracy that involves more input from local residents and other non-experts. These demands often conflict with the increasing complexity of problems and the real...
Bicyclists are one of the highest and most vulnerable road users. This is due to the higher likelihood of being seriously injured when involved in a crash. This research seeks to understand two different behavioral interactions of an implemented facility user: the motorist (secondary user) and bicyclist (primary user). The...
