Demographic features of a lapland longspur population near Barrow, Alaska Demographic features of a lapland longspur population near Barrow, Alaska

Breeding density, clutch size, hatching and fledging success, and survival of adult Lapland Longspurs (Calcarius lapponicus) were monitored over a 7-year period near the Naval Arctic Research Laboratory, Barrow, Alaska. Nesting begins as soon as the tundra starts to clear of snow and appears to be timed so that the young of the year reach independence before the end of adult insect...

Low-flow characteristics of Minnesota streams Low-flow characteristics of Minnesota streams

Low-flow frequency data for 161 continuous-record gaging stations having eight or more complete years of record are presented for 1-, 7-, 14-, 30-, 60-, 90-, 120-, 183-, and 365-day low flows for frequencies ranging from once in 2 years to once in 100 years. In addition, 8,146 low-flow measurements at 1,515 sites are given. Included are measurements at 623 partial-record stations where

Techniques for estimating magnitude and frequency of floods in Minnesota Techniques for estimating magnitude and frequency of floods in Minnesota

Estimating relations have been developed to provide engineers and designers with improved techniques for defining flow-frequency characteristics to satisfy hydraulic planning and design requirements. The magnitude and frequency of floods up to the 100-year recurrence interval can be determined for most streams in Minnesota by methods presented. By multiple regression analysis, equations...

Low-flow characteristics at gaging stations on the Wisconsin, Fox, and Wolf rivers, Wisconsin Low-flow characteristics at gaging stations on the Wisconsin, Fox, and Wolf rivers, Wisconsin

Low-flow characteristics are presented at eleven gaging stations on the main stem of the Wisconsin, Fox, and Wolf Rivers in this report. The low-flow characteristics presented are the annual minimum 7-day mean flow below which the flow will fall on the average of once in 2 years (Q7, 2) and the annual minimum 7-day mean flow below which the flow will fall on the average of once in 10...

Baseline water quality of Long Meadow Lake, Ponds AP-9 and AP-10, and Black Dog Creek, Hennepin and Dakota counties, Minnesota Baseline water quality of Long Meadow Lake, Ponds AP-9 and AP-10, and Black Dog Creek, Hennepin and Dakota counties, Minnesota

Long Meadow Lake, Black Dog Creek, and Ponds AP-9 and AP-10 which lie in an area designated for a trunk highway bridge crossing the Minnesota River, were sampled for baseline water quality prior to construction of the bridge. Data collected show that dissolved solids fluctuate seasonally. Dissolved oxygen:/ranged from less than 1 milligram per liter under an ice cover to 13-9 milligrams...

Chemical composition of blood and bile of the shovelnose sturgeon Chemical composition of blood and bile of the shovelnose sturgeon

Samples of gallbladder bile and blood from shovelnose sturgeons (Scaphirhynchus platorynchus) collected from the Chippewa River, Wisconsin, contained concentrations of Na+, K+, Ca++, Mg++, Cl-, inorganic phosphate, and total cholesterol closely comparable with those reported for similar samples from other species of freshwater sturgeons.
