Microphytic crusts: 'topsoil' of the desert
Jayne Belnap
1990, Permaculture Drylands Journal (10) 4-5
Deserts throughout the world are the home of microphytic, or cryptogamic, crusts. These crusts are dominated by cyanobacteria, previously called blue-green algae, and also include lichens, mosses, green algae, microfungi and bacteria. They are critical components of desert ecosystems, significantly modifying the surfaces on which they occur. In the cold...
Pattern of solute movement from snow into an upper Michigan stream
R. Stottlemyer, D. Toczydlowski
1990, Canadian Journal of Fisheries and Aquatic Sciences (47) 290-300
Precipitation, snowpack, snowmelt, and streamwater samples were collected in a small gauged watershed draining into Lake Superior during winter 1987–88 to assess the importance of snowmelt pattern and meltwater pathways in the occurrence of solute pulses in streamwater. The snowpack along the south shore of Lake Superior can contain 50%...

Evolution of sedimentary basins: Powder River Basin
Vito F. Nuccio, Paula L. Hansley, William A. Cobban, Carroll G. Whitney
1990, Bulletin 1917
A multidisciplinary approach to research studies of sedimentary rocks and their constituents and the evolution of sedimentary basins, both ancient and modern....
Habitat relationships and nest site characteristics of cavity-nesting birds in cottonwood floodplains
James A. Sedgwick, Fritz L. Knopf
1990, Journal of Wildlife Management (54) 112-124
We examined habitat relationships and nest site characteristics for 6 species of cavity-nesting birds--American kestrel (Falco sparverius), northern flicker (Colaptes auratus), red-headed woodpecker (Melanerpes erythrocephalus), black-capped chickadee (Parus atricapillus), house wren (Troglodytes aedon), and European starling (Sturnus vulgaris)--in a mature plains cottonwood (Populus sargentii) bottomland along the South Platte River...
Kidney lesions associated with mortality in chickens inoculated with waterfowl influenza viruses
R.D. Slemons, L. N. Locke, Martha G. Sheerar, R. M. Duncan, Virginia S. Hinshaw, B.C. Easterday
1990, Avian Diseases (34) 120-128
Seventy-six type A influenza viruses recovered from waterfowl in Wisconsin, California, South Dakota, Florida, Texas, Alabama, and Nebraska were tested for virulence in chickens. The challenge to chickens was intravenous inoculation of first-, second-, or third-egg-passage virus. Each of the virus strains was tested separately in three or four chickens....
Comparative susceptibility of Culex tarsalis, a Nopheles franciscanus, and Culiseta inornata (Diptera: Culicidae) to Plasmodium relictum (Haemosporidia: Plasmodiidae)
Thierry M. Work, Robert K. Washino, Charles van Riper III
1990, Journal of Medical Entomology (27) 68-71
Repeated laboratory attempts failed to infect Culiseta inornata (Williston) and Anopheles franciscanus McCracken with Plasmodium relictum as efficiently as Culex tarsalis Coquillett controls. Of 210 An. franciscanus that imbibed a replete meal from a parasitemic canary, two were found with oocysts and none with sporozoites. Of 112 Cs. inornata similarly...
