Predicting the physical effects of relocating Boston's sewage outfall Predicting the physical effects of relocating Boston's sewage outfall
Boston is scheduled to cease discharge of sewage effluent in Boston Harbor in Spring 2000 and begin discharge at a site 14 km offshore in Massachusetts Bay in a water depth of about 30 m. The effects of this outfall relocation on effluent dilution, salinity and circulation are predicted with a three-dimensional hydrodynamic model. The simulations predict that the new bay outfall will...

The presence of high-affinity, low-capacity estradiol-17β binding in rainbow trout scale indicates a possible endocrine route for the regulation of scale resorption The presence of high-affinity, low-capacity estradiol-17β binding in rainbow trout scale indicates a possible endocrine route for the regulation of scale resorption
High-affinity, low-capacity estradiol-17β (E2) binding is present in rainbow trout scale. The Kd and Bmax of the scale E2 binding are similar to those of the liver E2 receptor (Kd is 1.6 ± 0.1 and 1.4 ± 0.1 nM, and Bmax is 9.1 ± 1.2 and 23.1 ± 2.2 fmol × mg protein-1, for scale and liver, respectively), but different from those of the high-affinity, low-capacity E2 binding in plasma (Kd...

Comparison of helicopter and ground surveys of waterfowl broods in southern Ontario Comparison of helicopter and ground surveys of waterfowl broods in southern Ontario
Managers often employ aerial survey information to manage waterfowl. Results of surveys by helicopter and from elevated platforms were compared to determine the accuracy of helicopters to detect waterfowl broods on beaver ponds in southern Ontario in 1996 and 1997. Fewer broods were detected from the helicopter than by observers in elevated platforms at wetland margins. When broods were

GIS interpolations of witness tree records (1839-1866) for northern Wisconsin at multiple scales GIS interpolations of witness tree records (1839-1866) for northern Wisconsin at multiple scales
To construct forest landscape of pre-European settlement periods, we developed a GIS interpolation approach to convert witness tree records of the U.S. General Land Office (GLO) survey from point to polygon data, which better described continuously distributed vegetation. The witness tree records (1839-1866) were processed for a 3-million ha landscape in northern Wisconsin, U.S.A. at...

The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report
The Cape Sable Seaside Sparrow (Ammodramus maritimus mirabilis) was listed as an original member of the federal list of endangered species in 1968. It is restricted to seasonally flooded prairies of extreme southern Florida and is disjunct from all other conspecific breeding populations (Kushlan et al 1982, McDonald 1988). Since the subspecies was described in 1919, its populations have...

Estuaries of the northeastern United States: Habitat and land use signatures Estuaries of the northeastern United States: Habitat and land use signatures
Geographic signatures are physical, chemical, biotic, and human-induced characteristics or processes that help define similar or unique features of estuaries along latitudinal or geographic gradients. Geomorphologically, estuaries of the northeastern U.S., from the Hudson River estuary and northward along the Gulf of Maine shoreline, are highly diverse because of a complex bedrock...

Regional effects of hydrologic alterations on riverine macrobiota in the New World: Tropical-temperate comparisons Regional effects of hydrologic alterations on riverine macrobiota in the New World: Tropical-temperate comparisons
This article has two main objectives: to examine what is known about regional effects of hydrologic modifications in temperate and tropical areas of the New World (i.e., North and South America and the Caribbean), with an emphasis on fishes and molluscs; and to discuss research needs regarding regional effects of hydrologic alterations in temperate and tropical regions. A better...

Species variation in osmotic, cryoprotectant, and cooling rate tolerance in poultry, eagle, and Peregrine Falcon spermatozoa Species variation in osmotic, cryoprotectant, and cooling rate tolerance in poultry, eagle, and Peregrine Falcon spermatozoa
Potential factors influencing spermatozoa survival to cryopreservation and thawing were analyzed across a range of the following avian species: domestic chicken (Gallus domesticus), domestic turkey (Meleagris gallopavo), golden eagle (Aquila chrysaetos), Bonelli’s eagle (Hieraaetus fasciatus), imperial eagle (Aquila adalberti), and peregrine falcon (Falco peregrinus). Studies focused on
