Modeling Seed Dispersal And Population Migration Given A Distribution Of Seed Handling Times And Variable Dispersal Motility: Case Study For Pinyon And Juniper In Utah, Ram C. Neupane
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The spread of fruiting tree species is strongly determined by the behavior and range of fruit-eating animals, particularly birds. Birds either consume and digest seeds or carry and cache them at some distance from the source tree. These carried and settled seeds provide some form of distribution which generates tree spread to the new location. Firstly, we modal seed dispersal by birds and introduce it in a dispersal model to estimate seed distribution. Using this distribution, we create a population model to estimate the speed at which juniper and pinyon forest boundaries move.
Secondly, we introduce a fact that bird …

Epa Superfund Record Of Decision: Murray Smelter Murray City, Ut, Epa
Epa Superfund Record Of Decision: Murray Smelter Murray City, Ut, Epa
All U.S. Government Documents (Utah Regional Depository)
The Murray Smelter Site ("the Site") is located in the city of Murray, Utah, in Salt Lake County as illustrated on Figure 1. The Site includes the former operational areas of the Murray Smelter and adjacent Germania Smelter which are referred to as the "on-facility" area., as well as surrounding residential and commercial areas where airborne emissions from the smelters impacted the environment or where contamination in shallow ground water may be transported in the future. These surrounding areas are referred to as the "off-facility" area. The on-facility area is approximately 142 acres. Its boundaries are 5300 South Street to …

The Utah Ecology Project: Ecological Impact Of Weather Modification Studies In The Uinta Mountains, United States Deparment Of The Interior, Bureau Of Reclamation
Elusive Documents
The Uinta Mountains are located in extreme northeastern Utah and
northwestern Colorado. The major portion of the range and all areas
rising above 3,050 m (10,000 ft) lie within five Utah counties (Daggett,
Duchesne, Summit, Uintah and Wasatch). The high elevation segment of
the range in Utah is commonly referred to as the High Uintas. This
report will consider only the so-called High Uintas.
Population Dynamics And Harvest Of Canada Geese In Utah, John Tautin
Population Dynamics And Harvest Of Canada Geese In Utah, John Tautin
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A twenty-one year (1952-72) accumulation of banding data for Canada geese in Utah was studied to determine the distribution and chronology of the harvest of the geese and the effects that hunting regulations have had upon harvests and population parameters. The banding data were also used in an attempt to develop a population model capable of predicting population trends and desirable survival rates.
Within Utah, the bulk of the annual harvest (78 percent) takes place in the northern portion of the State in the vicinity of the Great Salt Lake marshes. In Northern Utah the harvest peaks on the opening …
Some Aspects Of Geochemistry Of The Water And Sediment Of Bear Lake, Idaho-Utah, Richard H. Fuller
Some Aspects Of Geochemistry Of The Water And Sediment Of Bear Lake, Idaho-Utah, Richard H. Fuller
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Development by man through the last half century has caused a number of changes in Bear Lake. These changes include the diversion of Bear River water into Bear Lake, the pumping of lake water back into the river, and the building of breakwaters and other obstructions along the shore of Bear Lake.
The diversion of Bear River water into the lake has resulted in a yearly addition of an estimated 36,000 metric tons of calcium into the lake, which has caused the precipitation of an estimated minimum 90,000 metric tons of aragonite. The pumping of Bear Lake water back into …
Bear Lake And Its Future, William F. Sigler
Bear Lake And Its Future, William F. Sigler
Faculty Honor Lectures
Even in such a wide-ranging and eternally changing field as biology, a few statements about certain aspects can be made with a minimum likelihood of their being refuted. In this class are the following: No two lakes are identical. Any given lake is simultaneously many things to many people. A lake is never static. The influence of a lake reaches far beyond its shores.
Bear Lake, Utah-Idaho, can be used to good advantage to exemplify the truth of these statements. It defies meaningful comparison with other lakes unless a mass of detailed statistics is employed. To the fisherman and water …
