Fire effects on vegetation diversity, structure, and successional dynamics in shrub-steppe and mixed conifer environments of the Hells Canyon, Idaho

Creator:: Havlina, Douglas William
Abstract:: The effects of fire severity on post-fire succession and shrub demography were quantified in shrub-steppe grasslands and subalpine forests in the Hells Canyon of the Payette National Forest, Idaho. Following the 1988 Eagle Bar Fire, species frequency, community diversity, fire adaptations, and stand ages were quantified at 12 plots in...

Contribution of Calcium Oxalate to Soil-Exchangeable Calcium

Creator:: Dauer, Jenny M. and Perakis, Steven S.
Abstract:: Acid deposition and repeated biomass harvest have decreased soil calcium (Ca) availability in many temperate forests worldwide, yet existing methods for assessing available soil Ca do not fully characterize soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it has been hypothesized that the highly insoluble biomineral Ca...

The effect of drought on the rate of photosynthesis, respiration, and transpiration in two ecotypes of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Zavitkovski, J.
Abstract:: The subject of this study was the determination of the changes in photosynthesis, respiration and transpiration in two ecotypes of Douglas-fir as caused by decreasing soil moisture content. The photosynthetic rate was also correlated with the relative turgidities of needles. All the above processes were greatly affected by decreasing soil...

Redefining the past : essays in diplomatic history in honor of William Appleman Williams

Creator:: Williams, William Appleman and Gardner, Lloyd C., 1934-
Abstract:: The essays in this collection do not cluster about a specific theme, nor do they present a single unified interpretative approach to issues in the history of American foreign policy. Above all, William Appleman Williams is a teacher. And good teachers are disappointed with conformity. No one would ever come...

Life history and environmental influences on avian incubation and parental care in songbirds

Creator:: Austin-Bythell, Suzanne H.
Abstract:: Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions. Incubation, in particular, is of interest because adults must provide an environment suitable for embryonic development through nest-building and contact-incubation. We evaluated how adult incubation constancy and nest visitation...

Biogeographic and experimental evidence for local scale dispersal limitation in central Panamanian forest birds

Creator:: Moore, Randall Phillips, 1965-
Abstract:: I examined the avian biogeography of the islands of Lago Gatun, Panama, in an effort to better understand the effects of forest fragmentation in this biodiverse region, and specifically to understand the importance of fragment isolation and the mechanism behind its effects on tropical bird distribution. I combined exhaustive surveys...

Non-biological uptake of zinc-65 from a marine algal nutrient medium

Creator:: Tomlinson, Richard Douglas
Abstract:: The nature and magnitude of experimental errors due to ⁶⁵Zn adsorption by inorganic surfaces was examined in a laboratory system designed to measure ⁶⁵Zn uptake by marine phytoplankton. In the pH range, 6.3±.1 to 7.5±.1, a precipitate formed in the algal nutrient medium selected for the system. To this seawater-base...
