title: The Ecological Effects of Fire on Stand Structure and Fuel Dynamics in Red Fir Forests of Mineral King, Sequoia National Park, California

description: MASTERS THESIS: Fire is an infrequent but vital factor in red fir forests. In order to study the structure and fire history of red fir forests, 3 large permanent plots were established in the Mineral King area of Sequoia National Park, California. All trees greater than 10 cm in height were mapped. Species, height, crown area, diameter at breast height, and crown class were recorded for each tree. Increment cores were obtained from 402 trees and fire scar sections were taken from 16 trees. Fuels were intensively sampled using the planer intersect method. Correction factors for the planer intersect method were developed that significantly improved the accuracy of measurement for ground fuel weights in the red fir forests. There is little evidence for secondary plant succession in red fir forests following disturbance because species composition is dominated by red fir at every growth stage. A pictorial model of red fir forest regeneration is presented. Stand regeneration takes place in relatively small openings created by fires or other disturbance factors. The quantity and composition of fuel in these openings is significantly different from that of mature forests. Red fir age structure is dominated by 1 to several age classes arranged in a complex mosaic of overlapping tree groups. Small-scale patterns average 10m across, and the large-scale patterns average approximately 30m in width. There is no evidence for progressive changes over time in the size of the age groups. Fire scar analysis of the study area showed that fires have been infrequent. Most fires may have been ignited by lightning during the relatively infrequent summer cyclonic storms. Indian burning was probably not a major factor affecting red fir forests. Historical fire behavior varied greatly due to differing weather conditions, stand structure, and fuel weight, and distribution. Evidence does not conclusively support the idea that the fire-free interval has been altered in this century. No fires have occurred in the study area since 1886, and this is in part due to fire suppression actions.

title: Ecological and Morphological Aspects of the Breeding Bird Community of Blodgett Forest, California

description: 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 3 dimensions were independent; 2. A wider niche implied a smaller territory; 3. Heavier species occupied larger territories; 4. NOs along the 4 dimensions were all dependent...5. NO patterns within the guild were significantly different from NO according to S2; 6. The distribution of territories on 2 sites indicates that the higher intrinsic diversity in site A is the result of greater territorial overlap rather than smaller territories; 7. Linear regressions between the morphological Euclidean distance and the NOs were significant and negative; 1,4, and 7, lead to the conclusion that perhaps competition within the guild is unlikely; whereas 5 indicates the opposite. The above results, coupled with results from the morphological data analysis indicate that: 8. Size does not determine the multidimensional NB, but when the NB was decomposed, different morphological characters correlate with the various NB components; 9. Variability in various morphological characters affect NB in different ways, and the niche-width variation hypothesis cannot be categorically rejected; 10. Short-tailed heavy birds, with long wings fly faster; 11. High wing-loadings and long tails characterize zig-zag flyers; 12. Migrant species are typified by long, wide and shallow bills, short wings, low wing-loadings, short mid-toes, long tarsi and heavy bodies; 13. Strictly insectivorous species have morphological characteristics that enhance foraging maneuverability (short wings, long tails, short mid-toes and long tarsi).

title: Distribution, Abundance, and Coexistence of Two Species of Sucker (Catostomus) in Sagehen Creek, California and Their Status in the Western Lahontan Basin

description: MASTERS THESIS: In 1982 (the researcher) initiated a study to examine any differences in the distribution and abundance between mountain and Tahoe sucker and to determine how these two similar species coexist in Sagehen Creek. Early in the study (she) noticed that the relative abundance of these species had shifted dramatically when compared to earlier reports. IN addition to Sagehen Creek, four nearby streams were surveyed in 1982 to locate both species. At all sites mountain sucker were either absent or rare and only 10 individuals were eventually collected. The apparent scarcity of mountain sucker was perplexing; early records had shown mountain sucker were not only present and abundant but were also more numerous than the associated Tahoe sucker at these sites. (She) expanded the study to address the following objectives: 1. To determine if significant shifts in the relative abundance of suckers have occurred in Sagehen Creek since early surveys, 2. To determine if similar shifts have occurred elsewhere, 3. To distinguish differences in the distribution and abundance between the two species of sucker in Sagehen Creek where both species still exist, and 4. To determine how mountain and Tahoe sucker manage to coexist in a relatively small segment of stream.

title: Quantitative Effects of Spider Predation on Arthropod Populations in the Eastern Sierra

description: MASTERS THESIS: A naturally occurring assemblage of spiders was manipulated in situ to determine the predatory effects on a multiple prey complex in an eastern Sierran mixed-conifer forest. Exclosures were used to vary the densities of spiders within treatment plots. Litter samples were then analysed to determine the relative abundance of epigeal collembolan prey resulting at each level of spider density. Probably as a result of cannabalism and predator-predator interference, exclosures with artificially high densities of spiders returned to normal spider densities within several weeks and relative collembolan abundance was not found to be significantly different from that found in controls. The sifting procedure used to reduce spiders in the spider reduction exclosures altered both rey and spider densities significantly, a procedure from which the collembola populations did not recover. The following year, pitfall trapping was used to remove spiders in a less destructive manner. However, sufficient numbers of spiders were not removed by this method during the study period, and no significant differences in relative collembolan abundance were detected between treatments and controls. Microcosms with controlled initial densities of spiders and collembola failed to maintain treatment integrity over the term of investigation and differences in resulting densities were due to chance alone. A critical review of the exclosure methodology used in community level studies of predation drawn from this experiment and the literature is made, and recommendations for a mesocosm-microcosm approach to future studies are presented.

title: Influence of Soil Moisture, Herbaceous Competition, and Small Mammals on Lodgepole Pine (Pinus contorta var. murrayana) Seedling Establishment in Sierra Nevada Meadows of California

description: DOCTORATE DISSERTATION: To test the hypotheses that vegetative competition and high water tables prevent successful establishment of lodgepole pine (Pinus contorta var. murrayana) in montane California Sierra Nevada meadows, three month old lodgepole seedlings were transplanted into dry, mesic and wet meadows in 1982 and 1983. Soil moisture was increased in dry and mesic meadows and decreased in wet meadows in combination with reduction of vegetative competition and protection from small mammal grazers. Seedling response to abiotic factors was assessed with a stress/mortality index based on non-green needles (NGN) which was linearly related to mortality. Shade reduced mortality. In 1982 with soil water potential between -0.2 and -0.3 MPa, NGN exceeded 0.6 but averaged 0.15 in plots without and with meadow vegetation. NGN and light exposure were correlated. Unusually high summer-long soil moisture in 1983 depressed NGN, which ranged from 0.15 to 0.40 compared to 0.15 to 0.80 in 1982. Survivorship after 3 months in protected control plots was 99 percent and 69 percent for 1983 and 1982 cohorts. I wet meadows after 3 years 0 percent seedlings at ambient water tables survived compared to 17 percent in plots elevated 15cm. First season unprotected control plot mortality from small mammals in 1982 was 8, 37, and 42 percent in dry, mesic and wet meadows and in 1983 was 37, 25, and 18 percent. After three years 50 percent of the 1982 cohort was killed by small mammals. Given the apparent lack of competition and the tolerance of seedlings to moderately high water tables, small mammals are critical in excluding seedlings from meadows. It was hypothesized that small mammals consume lodgepole seeds, but that cleared patches within meadows discourage seed predation thereby increasing seed longevity. Percent lodgepole seeds remaining in Petri dishes in cleared 0.00, 0.35, 1.00, 2.00 m diameter plots averaged 10, 26, 21, 60 percent after 24 hours. Presence of small mammal feces was linked with seed predation. Seeds remaining on the ground in 0.00, 0.35, 0.77, 1.00 m patches averaged 33, 40, 88, 79, percent after 5 days. Small mammal seed predation in meadows can be substantial but was reduced in cleared areas larger than 0.5m.

title: Upstream Changes in Native Fish Abundance After Reservoir Impoundment in California Streams of the Lahontan Basin

description: MASTERS THESIS: Native fish population surveys were conducted in five California streams of the Truckee River system in the western Lahontan Basin in July and August, 1987. Areas sampled were above impoundments in four streams and below an impoundment in Martis Creek. Results were compared to surveys both before and after stream impoundment. Native fishes were virtually absent in Martis creek and scarce in the Little Truckee River. Compared to 1982-83 surveys, fish numbers increased measurably in both Sagehen Creek and Prosser Creek, exhibiting a measure of persistence and resilience to disturbance. However, in Sagehen Creek, the increased fish abundance was limited to two native species and an area normally inundated by the reservoir. Although, Alder Creek and Prosser Creek supported sizable populations of mountain sucker (Catostomus platyrhynchus) and Lahontan speckled dace (Rhinichythys osculus robustus) in portions of their lower sections, mountain sucker, Lahontan speckled dace, and mountain whitefish (Prosopium williamsoni) were generally scarce throughout the five streams. Stream impoundments are suspected of creating conditions leading to the extinction of mountain sucker, Lahontan speckled dace, and mountain whitefish in upstream areas. Principal reasons are loss of habitat, greater environmental variability from fluctuating reservoir levels, and increased barriers to migration.

title: The Response of Trout to Beaver Dams in Sagehen Creek, California

description: MASTERS THESIS: This study examines the response of trout to beaver dams under low summer flows and following winter flood conditions in Sagehen Creek, California. For purposes of this study, a response is defined as a shift in habitat utilization as indicated by a change in density or age structure of the trout populations. Little work has been done to investigate the response of trout to beaver (Castor canadensis) dams in Western mountain streams, although substantial data exist for eastern and Midwestern streams. No follow up studies have been done on streams in California since the pioneering work of Gard. Further, no published study has specifically examined the role beaver dams play in providing physical habitat for trout in years of high and low flows. Two consecutive, extreme water years in 1986 and 1987 provided the opportunity for such an investigation. Flows in Sagehen Creek in February through May of 1986 were substantially above mean monthly flows for the period of record, 1954-1985. By July of 1986, however, flows had dropped to normal summer levels for this stream. Hydrologic conditions the following year were fairly typical of a drought year, with flows consistently below monthly mean flows. The objective of this investigation were to describe the physical characteristics of stream reaches with and without beaver activity, to examine changes in physical characteristics of both types of reach under yearly flow variations, and to identify responses of trout to those physical habitat characteristics and changes.

title: The Ecology of Spacing Behavior in the Yellow-Billed Magpie (Pica nuttalli)

description: DOCTORATE DISSERTATION: The yellow-billed magpie is a highly social corvid that breeds in loosely spaced colonies. Nesting close to conspecifics, rather than nesting in dispersed locations, is known to increase competition (for food, nest sites and mates) and increase the spread of disease and parasites. For coloniality to be evolutionarily stable, some benefit, or combination of benefits, must counter these inherent costs. Among several alternative hypotheses for the evolution of avian coloniality, I examined a model which relates the variability of foraging areas to selection for nesting in colonies. In a simple model, Horn showed that when resources were evenly distributed, breeding pairs nesting in dispersed locations had shorter average travel distances to foraging areas than pairs nesting in a cluster. When resources were clumped in space and time, breeding pairs nesting colonially in a central location had shorter average travel distances to unpredictable foraging areas. Thus, the minimization of travel distance to foraging areas will select for coloniality when resources are clumped in space and time. The model makes several assumptions: 1. Food resources must be spatially and temporally variable while the colony is occupied. 2. Colony locations should be near the center of mass of the food distribution. 3. Every colony member should forage throughout the entire foraging area exploited by the colony. The model s prediction is that, given these assumptions, mean travel distances should be shorter for colony members than those calculated for members of a hypothetical population of equal size that is dispersed over the same food distribution. I evaluated the assumptions and prediction of Horn s model using field data from a long-term study of yellow-billed magpies. Yellow-billed magpie nests were clustered relative to available habitat and individuals were not forced to nest in colonies because of habitat limitation. The location of good foraging areas varied significantly in space and time. Yellow-billed magpie colonies were roughly centrally located with respect to the distribution of food. Foraging areas were not defended and individual home ranges, as determined by radio telemetry, exhibited significant overlap. Consistent with Horn s model, mean travel distances were significantly shorter for colony members than those calculated for members of hypothetical populations of equal size that were dispersed over the same food distribution.
