Variation in the seasonal water level fluctuations of tropical and subtropical wetlands controls the production and concentration of aquatic fauna that support breeding wading birds. However, little is known about how particular components of the annual hydrologic cycle affect processes that control food availability and reproduction.

Show moreVariation in the seasonal water level fluctuations of tropical and subtropical wetlands controls the production and concentration of aquatic fauna that support breeding wading birds. However, little is known about how particular components of the annual hydrologic cycle affect processes that control food availability and reproduction. This thesis identifies specific mechanisms responsible for transforming wet season prey standing stock into dry season prey concentrations, links landscape hydrological patterns to wading bird nesting, and presents a predictive model of Wood Stork nesting. I examined the supoort for several a priori hypotheses of factors affecting wading bird prey concentrations and wading bird nest effort. Factors affecting the concentration and vulnerability of prey were important for transferring secondary production to higher trophic levels. Receding water levels, microtopographic variation, and high standing stocks of prey were critical for generating pulses of food availabiltiy to meet the high energy requirements of breeding predatory birds.

Abstract/Description

Understanding the foraging and nesting ecology of Wood Storks will play an important role in Everglades restoration because this species has specific resource requirements during the breeding season which ultimately affect nest success. I conducted a foraging habitat use and selection study, which indicated that Wood Storks from coastal colonies, Paurotis Pond and Rodgers River Bay, require a narrow range of water depths in the mangrove-saltwater marsh ecotone near their colonies as well in...
Show moreUnderstanding the foraging and nesting ecology of Wood Storks will play an important role in Everglades restoration because this species has specific resource requirements during the breeding season which ultimately affect nest success. I conducted a foraging habitat use and selection study, which indicated that Wood Storks from coastal colonies, Paurotis Pond and Rodgers River Bay, require a narrow range of water depths in the mangrove-saltwater marsh ecotone near their colonies as well in the freshwater marsh habitats of the inland Everglades. Wood Storks nesting at the inland colony, Tamiarni West, relied heavily upon nearby freshwater marsh habitat and selected foraging sites associated with shrub swamp habitat as well as optimal water depths. The observational nesting ecology study of Wood Storks showed marked differences in parental nest attendance and food delivery rates between the two years of study, 2005 and 2006, which had different hydrological patterns.
