title: PsPM-FR: SCR, ECG and respiration measurements in a delay fear conditioning task with visual CS and electrical US.

description: This dataset includes skin conductance response (SCR), electrocardiogram (ECG) and respiration measurements. Also included are CS and US information, keypress responses and keypress response times for 23 healthy unmedicated participants (06 males and 17 females aged 23.43+/-3.79 years) participating in a classical (Pavlovian) discriminant delay fear conditioning task. CS were a red and a blue rectangle. US consisted of 0.5 s square electric pulses with 0.2-ms duration and 10 Hz frequency. SOA between the CS onset and US was 3.5 s. CS and US co-terminated. During extinction phase, an auditory startle probe (ST) was delivered 3.8 s after CS onset via headphones (100 dB, 50 ms duration with 2ms on- and offset ramp). The ITI was randomly determined on each trial to be 7, 9, or 11 s.

title: The factors Governing the Maintenance of Gynodioecy in Sidalcea oregana ssp. spicata (Malvaceae)

description: DOCTORATE DISSERTATION:Gynodioecious populations contain both hermaphrodite and female plants. This dimorphism results in an inequality in the potential genetic contributions of the sex morphs. Females can contribute genes only through ovules, whereas hermaphrodites can contribute through both pollen and ovules. Thus, females must experience a compensatory advantage to be maintained. This advantage could be realized through higher seed production or production of higher quality seeds. The focus of this dissertation research was to evaluate the factors that could be operating to maintain females in gynodioecious Sidalcea oregano ssp. spicata (Malvaceae) at Sagehen Creek Field Station, in the Sierra Nevadas. I investigated the importance of both pollination and resource allocation in determining patterns of seed production by the sex morphs. The sex morphs receive equivalent and sufficient levels of pollination but females produced 10 percent more seeds than hermaphrodites. The sex morphs allocated similar total amounts of resources to reproduction on a whole-plant basis but females allocated a greater proportion to seeds while hermaphrodites allocated proportionately more to flowers. To study the factors that influence seed and seeding quality in the greenhouse and in the field I used a breeding design which allowed me to separate the effects of maternal sex and inbreeding. After the first year of growth in the greenhouse a selfed hermaphrodites offspring had an expected cumulative fitness of only 74 percent that of an outcrossed offspring. When levels of out-crossing were equivalent, offspring of females were 91 percent more fit than progeny of hermaphrodites. It is unlikely that resource provisioning differences created this substantial fitness differential; seeds produced by the sex morphs did not differ significantly in biomass, nitrogen or phosphorus content. It is possible that this fitness differential was due to genetic (cytoplasmic) maternal effects. Under different conditions of resource availability, however, sex-specific resource allocation could result in provisioning differences that do affect fitness. I manipulated resource availability by adding NPK fertilizer to plants in the field. The sex morphs responded differently to these conditions in terms of flowering time, seed production, and per seed allocation. Hermaphrodites prioritized pollen allocation over seed allocation. Sex-specific allocation patterns can be interpreted as fitness optimizing strategies, and may play an important role in the maintenance of gynodioecy in Sidalcea, especially if resources vary.

title: The Physiological Benefit of Leaf Flutter in Poplars

description: DOCTORATE DISSERTATION: Poplars (Populus spp.) have, in general, a flattened non-rigid petiole oriented perpendicular to the blade causing the leaf to flutter in even light winds. This study tested three hypotheses concerning the adaptive significance of this trait. Leaf flutter may enhance whole canopy carbon gain by a. creating a more dynamic light environment in the understory, b. maintaining more favorable leaf temperatures or c. increasing the CO2 flux of the leaf. Leaf flutter caused high frequency variations (from 3 to 5 Hz) of light in poplar (Populus tremuloides Michx. And P. fremontii Wats.) canopies. Flutter decreased the light interception of leaves at the top of the canopy, allowing increased light penetration into the understory. Leaf flutter created a canopy light environment that was more dynamic temporally and more evenly distributed spatially. An increase in the dynamics of the understory light environment would increase the utilization efficiency of transient light. Post-illumination CO2 fixation contributed proportionally more to the carbon gain of leaves during short frequent light flecks than longer less frequent ones. Leaves of these poplars become photosynthetically induced quickly and activation of Rubisco was the primary limitation for induction. Fluttering leaves at the top of the canopy were 2 to 4 degrees C. cooler than constrained leaves. However, lower canopy leaves showed no such reductions in temperature. Temperature differences of upper canopy leaves can be attributed to an increase in convective heat exchange or a decrease in light interception or both. However, this decrease in upper canopy leaf temperatures would increase whole canopy carbon gain only slightly and then only during the warmest ambient temperatures. Flutter can increase the CO2 flux of poplar leaves. However, neither an increase in boundary-layer conductance s or bulk flow can account for significant increases in intercellular CO2 concentrations or photosynthetic rates for these poplars. It is the conclusion of this study that the primary adaptive significance of leaf flutter appears to be the enhancement of canopy light environments and any enhancement of leaf temperatures or CO2 flux should be considered secondary benefits.

title: Ecophysiology of mutualism in a unique stream symbiosis between a polymorphic cyanobacterium, Nostoc parmelioides, and the larvae of the midge Cricotopus nostocicola

description: DOCTORATE DISSERTATION: In mountain streams, larvae of Cricotopus nostocicola develop symbiotically with colonies of Nostoc parmelioides. They cause the spherical colonies to become disk shaped and lie horizontally on the substrate (pies), or to protrude vertically into the flow (ears). I used field observations and manipulations, laboratory experiments and mathematical models to investigate the population ecology of this symbiosis, and its interactions with its physical environment. Field work was done in Sagehen Creek, California. In Chapter 1, I describe the seasonal changes in population dynamics of the two Nostoc morphologies. Using SOLRAD, a light interception model, I found that the induction of a seasonally appropriate morphology enables Nostoc colonies to best utilize available light in seasonally different population densities. Morphological changes are important in aquatic environments, because the magnitude of the mechanical forces exerted by the current depends on colonies size, shape and orientation to water flow. By manipulating macro-flow regime in situ, and using scaled models in a wind tunnel, I found that unoccupied spheres are susceptible to dislocation; drag forces do not significantly affect survival of ears or pies in Sagehen Creek, yet colonization seems to be flow related. In streams, thermal regime is important. Temperature can change the balance between Nostoc production and consumption by the midge, thereby changing the nature of the interaction. The results of a simple theoretical model suggest that to maintain a mutualistic interaction, the joined respiration of the symbiosis and Nostoc s photosynthetic response should change seasonally with changes in water temperature. This can be brought about by the seasonal morphological changes that the larvae induce in Nostoc colonies. In an experimental test in situ, I found that within the temperature range tested, the presence of the midge always contributed positively to growth in Nostoc colonies. I suggest that the morphological change that Cricotopus nostocicola larvae induce in Nostoc parmelioides colonies helps in maintaining the mutualistic nature of the symbiosis by optimizing the interactions between the symbiosis and its physical environment.

title: Inhibition of Conifer Regeneration by an Herbaceous Perennial, Wyethia mollis, in the eastern Sierra Nevada, California

description: DOCTORATE DISSERTATION: Wyethia mollis is a long-lived, herbaceous perennial. It dominates extensive herbaceous patches of the Sierra Nevada on the east slope yellow pine forests resulting from overgrazing by domestic ungulates after loss of forest canopy. Little regeneration of pines occurs in these patches which are believed to persist for greater than 60 yrs. Previous studies using tissue extracts in controlled settings and in situ over-wintering bioassays indicated that Wyethia exhibits a potential for allelopathic interference on germinating pine seeds. Also, rodent predation of pine seed was found to be effective in reducing the availability of seed within these patches. A second study found that the presence of W. mollis was correlated significantly with decreased survival and growth of Pinus jeffreyi saplings. The current study was designed to further examine the role of allelopathy in pine suppression; to examine seedbed microclimate and water availability; to study pine growth in association with Wyethia (field and controlled environments); and to characterize pine seedlings grown with montane chaparral, Great Basin steppe, and yellow pine forest. Results indicate that pine seedbed microclimate is greatly influenced by snowpack size and duration as well as the presence of vegetation and litter. Soil water, while not limiting in the early summer, becomes limiting to pines later in association with W. mollis, restricting establishment and survival through summer drought. Nutrient availability is not limiting in W. mollis patches. Seed predation by rodents, seedling herbivory and bioturbation damage both by rodents and domestic sheep reduced pine establishment. Allelopathy in the seedbed appears to vary with precipitation and snowpack. Mycorrhizae, both ectomycorrhizae of pines and vesicular-arbuscular mycorrhizae of Wyethia and bioassay species, are not reduced in association with Wyethia suggesting that patches are not hostile sites for these fungi. Patch persistence is discussed in light of continued conifer suppression. Pine establishment is inhibited in Wyethia patches by a synergism of factors rather than a single causal element. These include rodent herbivory and bioturbation, variability in snowpack and precipitation, and seedbed allelopathy.

title: The Manzanita Leaf-gall Aphid, Tamalia coweni (Cockerell) (Homoptera: Aphididae) as a Model System for Studies in Elementary Social Behavior, Sex Allocation and Life History Evolution

description: DOCTORATE DISSERTATION: I present life history details for a California population of the gall-forming aphid, Tamalia coweni, on its host plants Arctostaphylos patula and Arctostaphylos viscida (Ericaceae). I document communal gall occupation by multiple aphid foundresses and place it into a sociobiological context. Relatedness among experimental groups of foundresses had no measurable effect on the rate of communal gall induction; therefore, I conclude that T. coweni foundresses do not actively discriminate among kin during gall initiation. Communal gall occupation was found to be closely correlated with foundress density, and individual aphid fitness was inversely related to the mean number of foundresses per gall. These results suggest that communal gall occupation does not represent mutual cooperation but is a function of competition for gall sites on the host plant. I measured sex ratio and sex allocation for T. coweni. Among broods with a sex ratio greater than zero (proportion male) there is a highly significant inverse relationship between brood size and sex ratio. Males are more likely to be produced towards the end of the growing season as resource quality deteriorates. The Trivers-Willard hypothesis of condition-dependent sex allocation bet fits these data for T. coweni. I outline the development of a microsatellite genetic marker and its application toward the goal of deciphering kin structure in galls of T. coweni. In all five singly-founded galls screened, genotypes were identical among foundresses and offspring within each gall. Identical genotypes among co-foundresses were found in four of ten communal galls; these preliminary data are consistent with the notion that communal gall occupation represents a form of passive cooperation and mutual tolerance among T. coweni foundresses, which is facilitated by kin selection. A novel wingless morph of T. coweni is described which resembles but does not behave like a soldier aphid. This morph is incapable of inducing galls; instead, it appears to occupy mature and abandoned galls. It is therefore termed a squatter. The occurrence of such a squatter morph in the population can be understood in the context of evolutionarily stable strategy analysis.
