East-west trap lines were set up to detect the arrival of the AHB front in Northern Guatemala and in the Atlantic and Pacific coastal areas of Mexico, from 1986-1989.
MASTERS THESIS: A four year investigation, 1966 through 1969, into the movements and food habits of coyotes was conducted in the Sagehen Creek basin and vicinity of northeastern California. This study employed mark-recapture techniques and scat analysis. It also includes a literature review on coyote food habits and movements.
This data contains a critical habitat boundary profile for gnatcatcher, tiger salamander, and california amole populations along the central coast. Maps outline specific critical areas and provides distribution of gnatcatcher populations. All maps are available on ArcView.
DOCTORATE DISSERTATION: The breeding biology and feeding patterns of the Oregon junco (Junco hyemalis thurberi) were studied in the Sagehen Creek basin in the central Sierra Nevadas of California, from Oct 1968 through July 1972. Breeding populations were followed in the yellow pine forest on the basin ridges and in the meadow areas along the basin bottom...... This project was designed to study the breeding ecology of the Oregon junco, and to compare populations in...
Biomass of ulvoid algae in Thatcher Bay, Blakely Island, Washington by species composition.
Demographic study of two rare annuals, Sand Gilia (Gilia tenuiflora arenaria) and Monkey Spineflower (Choriganthe pungens pungens). Data on number of seedlings produced, reproductive abilities, and growth rates of these historically rare plants was collected.
This study will explore how to restore an area most successfully by examining the effects of seed source location on a population%26#239;%26#191;%26#189;s genetic variance and fecundity. I hypothesize that restoration populations seeded with foreign genotypes will experience a greater breakdown in canalization, and, therefore, a greater increase in genetic variance than restoration populations seeded with local genotypes I will chose my study sites in accordance with the habitat matching model to avoid a significant decrease...
List of plant species (common and scientific names) found in Sur Sur Ranch, in alphabetical order by genus. Some species inexplicably marked by asterisks.
List of acorn woodpecker (Melanerpes formicivorus) granaries examined in 1991, with tree species, date, and some other unclear numerical data provided.
A record of sea surface temperatures was taken across 2 years, at coastal sites on reserve. Water samples were taken every two minutes at the top, middle, and bottom of two, 20 meter moorings.
Fish catch records from a subset of commercial fishers operating in the Big Sur area, who volunteered to contribute their landing receipts to this study. Data focuses on rockfishes captured, subdivided by species and groups of species. Also contains an authorless write-up about the motivations and conclusions of the study, veering into a history of the sardine fishery in Monterey. Also contains a graph of â gopher fish â caught from January-December 1992.
Three grids were live-trapped for small mammals beginning in January 2003. Grids were trapped for 2-3 nights at least every 3-5 weeks throughout the year. Data collection is ongoing. For each animal captured, data recorded included trap location, ear tag number, species, sex, reproductive condition, and body mass. The primary purpose of the study was to monitor the population dynamics of brush mice (Peromyscus boylii) in oak woodland and chamise chaparral habitat types. Other species...
Plants were collected within the property boundaries of Murray State University's Hancock Biological Station (HBS), located in northeast Calloway County, Kentucky and a few other localities. Specimens were identified, pressed, and archived. For each specimen collected, data were recorded for date, genus, species, subspecies, authors, common name, location, habitat, collector, relative abundance, and life form. The earliest collection from the HBS grounds was in 1969 and several were made in 1981 and 1982. The majority...
Description of vegetation in both quadrangles, including plant communities and common species.
Masters Dissertation Summary: A comparative live-trapping study was made in a cutover forest area at 6400 feet elevation, seven miles north of Truckee, California. Different methods of trapping and analysis of data were evaluated, and observations of population size and structure and movement patterns of each species were compared. The species included the chipmunks Eutamias amoenus and E. speciosus, the golden-mantled ground squirrel Citellus lateralis, and the deer mouse Peromyscus maniculatus.
DOCTORATE DISSERTATION: Weasels are probably the most widespread and common carnivores that prey extensively on voles and lemmings....... In April 1966 at Sagehen Creek in the Sierra Nevada, California, I found that 15 per cent of the winter nests of montane voles (Microtus montanus) exposed as the snow melted had been occupied by weasels. The investigation reported here grew out of this observation.
All sorts of water quality data for Central Coast watersheds. Includes measurements of bedload, discharge, Escherichia coli, fecal coliform bacteria, ammonia, nitrate, pH, phosphate, suspended sediment, water level, total dissolved solids, water temperature, total nitrogen, total phosphorus, transparency, and turbidity, among other data types.
A series of 40 plots on Hastings and 40 plots on adjacent grazed ranches (Oak Ridge, Rana Creek, Carmel Valley Ranch) were sampled with 20, 0.1 sq. m Daubenmire quadrats. Data are online.
MASTERS THESIS: Marten (Martes americana) habitat preferences were assessed in the Sagehen Creek Watershed, Tahoe National Forest, California, from July 1979 to September 1980. Fourteen martens were captured 47 times. The incidence of marten tracks on smoked aluminum plates in 42 baited plywood cubbies indicated that martens prefer red fir and riparian habitat associations: brush and Jeffrey pine associations were selected against. Radio-locations for 1 male and 3 female martens indicated preference for riparian associations...
A collection of seeds was taken from a variety of flora specimens, to ensure the preservation and representation of their genetic diversity and distribution. Currently a seed collection campaign of 26 species comprising 20 genera is under development. These seeds will aid in future recovery projects.
Accounts of bald eagle sightings at the Landels-Hill Big Creek Reserve following the reintroduction of the species into the area around 1991. It is noted that no bald eagles had been seen in the area from at least 1982 until the reintroduction. Accounts describe the age class of the eagle, where it was sighted, and its behavior. Last observation recorded is in 1994.
Point count surveys were conducted in 1998 and 2003 along the Salinas and Nacimiento River corridors to determine avian assemblages in response to Brown-headed Cowbird and European Starling Removal Project.
Raw and sorted data for height of Big Creek. Includes time of day and notes for each measurement. Graphs of creek height for one-year intervals from 1995 to 2001.
Research Use: A substantial number of faculty research projects are currently being conducted at the reserve. Marine and intertidal studies include: Dr. Louis Botsford (Wildlife
DOCTORATE DISSERTATION: Data on the foraging method, foraging tree species, foraging height, territory sizes and 10 morphological measurements for foliage-feeding bird species in a mixed conifer forest in the central Sierra Nevada were collected during the summers of 1978, 1979, 1980. Niche breadth and overlap were calculated for the data nad for 2 simulations: S1-random and uniform electivities of resource states, and S2-random re-arrangement of observed resource electivities. The results indicate that: 1. NBs along...
