Capture-recapture analysis of a wintering black-capped chickadee population in Connecticut, 1958-1993 Capture-recapture analysis of a wintering black-capped chickadee population in Connecticut, 1958-1993

We investigated the dynamics of a wintering population of Black-capped Chickadees (Parus atricapillus) using data from a long-term capture-recapture study. Goodness-of-fit and likelihood-ratio tests indicated that the standard Jolly-Seber model was inadequate for the data, so we explored different parameterizations of a model in which survival probability for new captures differed from...

Upper Eocene sequence stratigraphy and the Absecon Inlet Formation, New Jersey Coastal Plain Upper Eocene sequence stratigraphy and the Absecon Inlet Formation, New Jersey Coastal Plain

We evaluate the age, benthic biofacies, and sequence stratigraphy of thick and well-recovered upper Eocene sediments from the New Jersey Coastal Plain. These strata are herein defined as a lithostratigraphic unit and named the Absecon Inlet Formation. The formation is divided into upper and lower portions. At its type locality in the Atlantic City borehole, the lower portion of the...

Variations in pore-water quality, mineralogy, and sedimentary texture of clay-silts in the lower Miocene Kirkwood Formation, Atlantic City, New Jersey Variations in pore-water quality, mineralogy, and sedimentary texture of clay-silts in the lower Miocene Kirkwood Formation, Atlantic City, New Jersey

Properties of and pore-water solute chemistry in confining units in the New Jersey Coastal Plain were studied to determine whether leakage of solute-enriched pore water from confining units affects regional aquifer-water chemistry, which ultimately may result in aquifer waters with high sodium and bicarbonate concentrations. Pore-water samples collected from a continuously cored borehole...

Population dynamics of white-winged scoters Population dynamics of white-winged scoters

A significant (P 0.01) decline between 1961 and 1993 in ratio of harvested young per adult in the Atlantic Flyway (age ration) of white-winged scoters (Melanitta fusca) led us to examine annual survival rates and harvest of this species. Compared to waterfowl with similar life histories, black scoters (M. nigra) and surf scoters (M. perspicillata), the decline in age ratios of white...

Iron and manganese oxide mineralization in the Pacific Iron and manganese oxide mineralization in the Pacific

Iron, manganese, and iron-manganese deposits occur in nearly all geomorphologic and tectonic environments in the ocean basins and form by one or more of four processes: (1) hydrogenetic precipitation from cold ambient seawater, (2) precipitation from hydrothermal fluids, (3) precipitation from sediment pore waters that have been modified from bottom water compositions by diagenetic...

Cometabolic biodegradation of trichloroethylene in microcosms Cometabolic biodegradation of trichloroethylene in microcosms

Laboratory microcosms were used to determine the concentrations of oxygen (O2) and methane (CH4) that optimize trichloroethylene (TCE) biodegradation in sediment and ground-water samples from a TCE-contaminated aquifer at Picatinny Arsenal, Morris County, New Jersey. The mechanism for degradation is the cometabolic activity of methanotrophic bacteria. The laboratory data will be used to...

Impact of an extreme event on the sediment budget: Hurricane Andrew in the Louisiana barrier islands Impact of an extreme event on the sediment budget: Hurricane Andrew in the Louisiana barrier islands

This paper examines the influence of Hurricane Andrew on the sediment budget of an 80-kilometer section of the Louisiana barrier islands west of the modern Mississippi delta. Because long-term bathymetric change has been extensively studied in this area, excellent baseline data are available for evaluating the impact of Hurricane Andrew. Results show that despite the high intensity of...

Sturgeon rivers: An introduction to acipenseriform biogeography and life history Sturgeon rivers: An introduction to acipenseriform biogeography and life history

We present an overview of the global distribution of all 27 living species of Acipenseriformes in an attempt to understand their biogeographic history and the range of life history patterns displayed by different species. Our biogeographic analysis (based on the most recent phylogenetic analysis including fossil Acipenseriformes) suggests that Acipenseriformes originated in Europe, and...
