Plum Island Ecosystems
We have designed and implemented a comprehensive study of a major, land-estuarine system in the Acadian biogeographic province in eastern New England (Fig 1). Our goal is to develop a predictive understanding of the long-term response of watershed and estuarine ecosystems at the land-sea interface to changes in climate, land use and sea level and to apply this knowledge to the wise management a...
متن کاملTotal System Metabolism of the Plum Island Sound Estuarine System.
In early summer 1995, we surveyed total system metabolism in the Plum Island estuary. Objectives included (1) estimation of ecosystem metabolism via open-water oxygen measurements, (2) determination of the autotrophic and heterotrophic regions of the estuary, and (3) comparison of the loading of organic carbon from the watershed to measurements of autochthonous production. Metabolism was calcul...
متن کاملHealth assessment of Black-crowned Night-herons (Nycticorax nycticorax) of the New York Harbor estuary.
Blood samples from 145 Black-crowned Night-heron (Nycticorax nycticorax, BCNH) chicks (mean age 3 weeks) were taken from four island colonies (Goose (2004), Canarsie Pol (2005), Hoffman (2004 and 2005) and North Brother (2004 and 2005)) in New York Harbor in 2004 and 2005 to establish baseline health reference ranges for this species and to compare health indices of birds reared on different is...
متن کاملLead poisoning in Canada geese on Plum Island, Massachusetts.
During December 1983 and early January 1984, about 200 Canada geese (Branta canadensis) died of lead poisoning at Parker River National Wildlife Refuge on Plum Island, Massachusetts. In an effort to determine the source of lead, 100 bottom samples were taken from a refuge impoundment where much of the mortality/morbidity occurred. An average of 157,150 pellets/ha was found with a range of 64,58...
متن کاملEcology and contaminant exposure of Lake Calumet Black-crowned Night Herons: Population Levels and Nesting Ecology Final Report
We examined a suite of organic and inorganic analytes in a sample of Black-crowned NightHeron (BCNH) embryos collected from a colony located adjacent to Lake Calumet in southeastern Chicago, Illinois, in 2002. Our objectives were to determine whether embryos from the Lake Calumet colony had greater exposure to environmental contaminants, when compared to samples from other contemporary populati...
