sarcocystis sp. in wading birds (ciconiiformes) from florida.sarcocysts were found in striated muscle of 21 adult wading birds among 145 examined grossly and 70 examined histologically (calculated prevalence = 24%), and in none of 332 immature wading birds examined from florida (usa). six of 12 species of ciconiforms were infected (ardea herodias, casmerodius albus, egretta caerulea, nyctanassa violacea, butorides striatus, eudocimus albus). cysts were filamentous, usually extended the entire length of the muscle fiber, and were visible grossly in 33% of ...19948151820
biomonitoring environmental contaminants near a municipal solid-waste combustor: a decade later.during the 1999 nesting season, eggs and nestlings of anhingas (anhinga anhinga) and white ibises (eudocimus albus) were collected from a colony located on the site of a municipal solid-waste (msw) combustor and analyzed for residues of chemicals potentially released from this facility. concentrations of most residues, including tetrachlorodibenzo-p-dioxin (tcdd). tetrachlorodibenzofuran (tcdf), arsenic, beryllium, cadmium and lead, were at levels comparable to those found during a similar surve ...200211843530
physiological condition of juvenile wading birds in relation to multiple landscape stressors in the florida everglades: effects of hydrology, prey availability, and mercury bioaccumulation.the physiological condition of juvenile birds can be influenced by multiple ecological stressors, and few studies have concurrently considered the effects of environmental contaminants in combination with ecological attributes that can influence foraging conditions and prey availability. using three temporally distinct indices of physiological condition, we compared the physiological response of nestling great egrets (ardea alba) and white ibises (eudocimus albus) to changing prey availability, ...201425184221
feather mercury concentrations and physiological condition of great egret and white ibis nestlings in the florida everglades.mercury contamination in the florida everglades has reportedly played a role in the recent decline of wading birds, although no studies have identified a mechanism leading to population-level effects. we assessed feather mercury levels in great egret (ardea alba; n=91) and white ibis (eudocimus albus; n=46) nestlings at breeding colonies in the florida everglades during a year (2006) with excellent breeding conditions (characterized by hydrology leading to concentrated prey) and a year with belo ...200919217646
wading birds as bioindicators of mercury contamination in florida, usa: annual and geographic variation.mercury contamination in wetland biota is often dynamic, difficult to predict, and costly to track. in this paper, we present results from a six-year study of growing feathers of piscivorous birds as monitors of wetland hg exposure in florida, usa, wetlands. between 1994 and 2000, we collected feathers of growing great egret (ardea alba) nestlings from colonies in the freshwater everglades of southern florida, and during 1998, feathers were collected from chicks of both great egrets and white ib ...200211804050
reproductive physiology of free-living white ibises (eudocimus albus) in the florida everglades.we measured plasma concentrations of testosterone, estradiol, progesterone, and corticosterone; and recorded changes in gonad size, body condition, molt, and brood patch development of free-living adult white ibises (eudocimus albus) during the breeding season in the florida everglades. white ibises are colonially breeding, long-legged wading birds that inhabit freshwater and estuarine wetlands. they have flexible breeding schedules (nest initiation dates can range from january to september) and ...200312899853
