Quantitative assessment of the shallow ground-water flow system associated with Connetquot Brook, Long Island, New York
Keith R. Prince, O. Lehn Franke, Thomas E. Reilly
1988, Water Supply Paper 2309
Streamflow on Long Island is derived principally from shallow ground water that flows above the deeper regional flow system. The movement of shallow ground water was studied during 1975-82 at Connetquot Brook, an undisturbed stream in Connetquot River State Park, in south-central Long Island, New York. The investigation encompassed (1)...
Eustrongylides sp. epizootic in young common egrets (Casmerodius albus)
Thomas J. Roffe
1988, Avian Diseases (32) 143-147
In May 1985, epizootic mortality was reported in common egrets (Casmerodius albus) on Avery Island, Louisiana. Subsequent investigation revealed that more than 400 birds died. Severe peritoneal nematodiasis (Eustrongylides sp.) was found on postmortem examination. A nearby breeding rookery on the same island was apparently unaffected. Reasons for this selective...
Phytoplankton growth rates in a light-limited environment, San Francisco Bay
Andrea E. Alpine, James E. Cloern
1988, Marine Ecology Progress Series (44) 167-173
Phytoplankton cells reside in a turbulent medium partitioned into an upper photic zone that sustains photosynthesis, and a lower aphotic zone that does not. In estuaries, vertical mixing rates between these 2 zones can be rapid (< 1 generation time) because of tidal stirring and because the mixing depth is...
Selenium accumulation in benthic bivalves and fine sediments of San Francisco Bay, the Sacramento-San Joaquin Delta, and selected tributaries
Carolyn Johns, Samuel N. Luoma, Virginia Elrod
1988, Estuarine, Coastal and Shelf Science (27) 381-396
Spatial distributions of selenium were determined in fine-grained, oxidized, surface sediments and in two benthic bivalves (Corbicula sp., a suspension-feeding freshwater clam, and Macoma balthica, a deposit-feeding brackish-water clam) within San Francisco Bay, the San Joaquin River and three river systems unlikely to be subject to selenium inputs. Biologically available selenium enters...
Nutritional values of waterfowl foods
Leigh H. Fredickson, Fredric A. Reid
1988, Fish and Wildlife Leaflet 13.1.1
wetland habitats throughout their annual cycles. Survival, reproduction, and growth are dependent on the availability of foods that meet nutritional requirements for recurring biological events. These requirements occur among a wide variety of environmental conditions that also influence nutritional demands. Recent work on nesting waterfowl has identified the female’s...
Remote sensing to petroleum exploration in the Qaidam Basin, China
Wang Wenyan, Song Jianguo, Zhang Jiong, Wang Tianxi, Fan Congwu, G. B. Bailey, John L. Dwyer
Holly C. Wagner, Leslie C. Wagner, Frank F. H. Wang, Florence L. Wong, editor(s)

Relationships between silicic plutonism and volcanism: Geochemical evidence
R. Macdonald, R.L. Smith
1988, Transactions of the Royal Society of Edinburgh, Earth Sciences (79 ) 257-263
Field associations (voluminous ash flow deposits, rhyolitic stocks and dykes, ring complexes), evidence of repeated influxes of mafic magma, and thermal constraints indicate that many high-level silicic plutons (magma chambers) acted as open systems for considerable parts of their history. The long thermal lifetime, as well as other evidence from...
Field validation of a habitat suitability index model for the American oyster
Thomas M. Soniat, Michael S. Brody
1988, Estuaries (11) 87-95
A habitat suitability index (HSI) model, developed for the American oyster,Crassostrea virginica, along the Gulf of Mexico, was field tested on 38 0.1-ha reef and nonreef sites in Galveston Bay, Texas. The HSI depends upon six (HSI1) or, optionally, eight (HSI2) variables. The six variables are percent of...
Habitat relationships of island nesting seabirds along Coastal Louisiana
Richard D. Greer, Carroll L. Cordes, Stanley H. Anderson
1988, Colonial Waterbirds (11) 181-188
Seabirds in the saline marsh of coastal Louisiana nest on the islands that are more isolated, smaller, have lower percentages of woody vegetation, and higher percentages of herbaceous vegetation and beach habitat. Only moderate variation in these habitat features was demonstrated among years of colonization. The factors...
