Applying Height Growth And Site Index Curves For Inland Douglas-Fir, United States Department Of Agriculture, Forest Service

Forestry

Methods for estimating both site index and dominant height growth for inland Douglas-fir in the Northern Rocky Mountains are presented and discussed. The methods should be applicable over a wide range of stand conditions because no restrictions were placed on species composition, stand density, spacing, or age structure in the original stem analysis sample. Increased accuracy can be obtained if habitat type is considered, because the shape of the site index curves varied with respect to three major habitat series groupings. Results are summarized in the form of equations, tables, and graphs. Precision curves are used to illustrate the relationship …

Effects Of Bifenox, Dcpa, And Napropamide On Ectomycorrhizal Development Of Conifer Seedlings In Central And Northern Rocky Mountain Nurseries, United States Department Of Agriculture, Forest Service

Forestry

Postseeding and postgermination treatments with three weed control herbicides (Bifenox, DCPA, Napropamide) at two rates of application caused little reduction of ectomycorrhizal development on 1- and 2-year-old conifer seedlings in Central or Northern Rocky Mountain nurseries. In many cases, herbicide treatment increased ectomycorrhizal development, particularly with DCPA. In general, herbicide treatment effects on ectomycorrhizal development were species and nursery specific.

A Quantitative Analysis Of Shoreline Erosion Processes, Lake Sakakawea, North Dakota, Mark D. Millsop

Theses and Dissertations

Shoreline erosion is a problem at Lake Sakakawea and Lake Audubon, North Dakota. Land is lost, water quality is adversely affected, and reservoir storage capacity is decreased.

Instrumentation of the eastern shores of both lakes began in 1983 to quantify bank erosion by process (e.g., wave erosion, rainsplash and runoff, and frost-thaw failure). Other data gathered included: pool level fluctuations; wind velocity, direction, and duration; precipita tion; soil moisture; frost penetration; freeze-thaw cycles; and geology (e.g., texture, clay mineralogy and structure).

The magnitude of shoreline erosion is highly variable, especially within Lake Sakakawea. For the interval of May 1983 through …

Two New Genera Of Cave-Dwelling Millipedes (Diplopoda), With Remarks On The Millipede Fauna Of West Caucasian Caves, Sergei I. Golovatch

International Journal of Speleology

Two new genera and species of the Diplopoda from Caucasian caves are described: troglobitic Caucasodesmus inexpectatus n.g., n.sp. (family Macrosternodesmidae) from a cave in North Osetia, North Caucasus, and troglophilic Ratcheuma excorne n.g., n.sp. (family Antroleucosomatidae) from a cave in Racha, Georgia, Transcaucasia. Millipedes of the western Caucasian cavernicolous fauna are reviewed as regards their distribution, relationship with caves and zoogeographical connections.

The Occurrence Of The Troglobitic Amphipod, Stygobromus Tenuis Tenuis (Smith) (Crangonyctidae) In The Taconic Mountains Of Southwestern Massachusetts (Usa): A Case For The Existence Of A Subterranean Refugium In A Glaciated Region, Douglas G. Smith

International Journal of Speleology

Stygobromus t. tenuis is one of only two species of troglobitic amphipods known to occur in the New England physiographic province. The rarity of subterranean organisms in New England is attributed to limited karst development and eradication of organisms from the region during glacial times. Traditionally it has been believed that those troglobitic species presently occurring north of the glacial terminus migrated there following glacial retreat from refugia south of the areas influenced by glacial conditions. However, a few recent studies favour the existence of subsurface refugia in glaciated regions during glacial times. Stygobromus t. tenuis is recorded from springs …

The Anatomy And Histology Of The Alimentary Tract Of The Blind Catfish Horaglanis Krishnai Menon, T. V. Anna Mercy, N. Krishna Pillai

International Journal of Speleology

H. krishnai is a blind catfish inhabiting the dug-out wells at Kottavam Kerala, South India. Studies on the alimentary tract of the fish show that, the alimentary tract, though typically teleostean, shows several adaptive modifications. The bulbous stomach helps in storing food which is helpful in an environment chronically deficient in food. The ileo-rectal sphincter helps in retaining the digested food in the intestine for a long duration to facilitate maximum absorption. This is very helpful as the intestine is short. The liver is well developed.

Late Quaternary Environmental And Climatic History Of The Southern Chilean Lake Region Interpreted From Coleopteran (Beetle) Assemblages, John W. Hoganson

Theses and Dissertations

A diverse Coleoptera fauna of 462 species in 48 families was collected from 41 locations in the Parque Nacional de Puyehue and adjacent parts of the Lake Region of southern Chile. The sample locations ranged from rain forest habitats at sea-level to Andean tundra habitats at 1500 m msl. Cluster analysis of a Dice similarity coefficient matrix revealed a broad pattern of bioassociations within the large data base, Boundaries between the bioassociations correspond largely with those of the major vegetation zones implying that the distribution of the fauna is strongly influenced by the distribution of plants. Evidence from fossils indicates …

A Pleistocene Jaguar From North-Central Nebraska, C. B. Schultz, Larry D. Martin, M. R. Schultz

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A nearly complete skull of an extinct jaguar, Panthera onca augusta from the Mullen Assemblage in Cherry County, Nebraska, provides new information concerning North American jaguars. The presence of Cervalces, Symbos, Tapirus, and Panthera onca in the Mullen Assemblage seems to indicate an extension of the Pleistocene spruce taiga into north-central Nebraska in the Early to Middle Illinoian.

Discharge And Travel Time Determinations In The Royal Spring Groundwater Basin, Kentucky, John Thrailkill, Douglas R. Gouzie

KWRRI Research Reports

Groundwater flow in many karst regions, including the Inner Bluegrass Karst Region of central Kentucky in which the study area was located, is unlike groundwater flow in granular aquifers. At least the major flows are turbulent and often with a free surface in large conduits, and applying concepts based on Darcy's Law to describe and model these flows is inappropriate. Parameters such as linear velocity, channel geometry, and conveyance used to describe surface streamflows are more applicable, and the primary objective of the project was to estimate these in a groundwater basin using the travel time of dye slugs and …
