Glacial Processes and Their Relationship to Streamflow Flute Glacier, Alaska

Flute Glacier is located at the head of the South Fork of Eagle River, Alaska, about twenty air-miles east northeast of Anchorage. It is a small north-facing glacier, approximately two miles long and half a mile wide, situated in a deep glacial valley (see Figure 1). Elevations on the glacier range from 3,500 feet at the terminous to 5,800 feet at the top of the accumulation area. Water from Flute Glacier becomes the South Fork of Eagle River, draining about 32 square miles of area compared to a 192 square mile drainage basin for Eagle River. Limited discharge measurements made during October 1968 suggest that the South Fork contributes about 20% of the water flowing down Eagle River. Glacial meltwater forms an important percentage of the waters of the Eagle River system. Glaciers feeding the main Eagle River are large, complex and difficult to study. Flute Glacier, relatively small and of simple plan, was selected for study because of its small size and proximity to the metropolitan area of Anchorage. Water from the Eagle River system is presently included in the plans for future water supply for Anchorage. The Eagle River valley up to the 500 ft contour is a federal power reserve. The climate of the area surrounding Flute Glacier is alpine with cool temperatures and higher than average precipitation for the area. All the glacier is above treeline so no plant life is obvious. Mountain sheep inhabit the sharp alpine peaks surrounding the glacier.The work upon which this report is based was supported by funds (Project A-021- ALAS) provided by the United States Department of the Interior, Office of Water Resources Research, as authorized under the Water Resources Act of 1964 as amended

\u3ci\u3eEpinotia Nisella\u3c/i\u3e: an Unrecorded Host and Mode of Feeding (Lepidoptera: Tortricidae)

The larva of Epinotia nisella is best known as a feeder in female catkins of Populus, primarily P. tremuloides Michx. in North America. In Minnesota, adults were reared from larvae boring in current-growth branchlets of P. balsamifera L., with no sign of like infestation in neighboring P. tremuloides, which has thinner branchlets. The behavioral variance is explained as plasticity in feeding biology, a characteristic of insects utilizing host reproductive structures whose abundance is periodic

Weights of \u3ci\u3ePolia Grandis\u3c/i\u3e Pupae Reared at Two Constant Temperatures (Lepidoptera: Noctuidae)

Sibling Polia grandis (Boisduval) larvae were reared at two constant temperatures on fresh foliage of quaking aspen (Populus tvemuloides Michx.). Female pupae developing at 25°C were 24% heavier than those developing at 30°C and corresponding males were 32% heavier. Duration of the larval period averaged 51 days at the former temperature and 41 days at the latter. Based on other Lepidoptera, a 24% change in pupal weight affects fecundity by 28 to 130 eggs per female. Fluctuations in larval temperature regime might induce size and fecundity variation in natural populations of grandis and other Lepidoptera
