Forest Stand Dynamics, Update Edition, Chadwick Dearing Oliver, Bruce A. Larson

Yale School of the Environment Other Publications

This book describes the various growth patterns of forests from a mechanistic point of view. Its purpose is to help silviculturists, forest managers, and ecologists understand and anticipate how forests grow and respond to intentional manipulations and natural disturbances. Demands on the forest have been increasing for timber production, wildlife habitat, water protection, recreation, and protection from fires, insects, and diseases. These demands have created an emphasis on prescribing site-specific treatments for individual stands of trees, rather than treating broad areas uniformly

A Unified Model For The Generation And Fission Of Internal Tides In A Rotating Ocean, Theo Gerkema

Journal of Marine Research

A new two-layer model consisting of generalized Boussinesq equations is derived which contains forcing terms due to barotropic tidal flow over large-amplitude bottom topography. These equations can describe both the generation of nonlinear dispersive internal tides and their disintegration into solitary waves. Special attention is paid to the effects of Coriolis dispersion (which is due to the earth's rotation). Numerical solutions based on observed oceanic conditions show convincingly that the earth's rotation can be a decisive factor at mid-latitudes in that it tends to impede the disintegration of the internal tide. Oceanic observations in the Celtic Sea and in Massachusetts …

The Principle Of Biological Attraction, Demonstrated By The Bio-Continuum Theory Of Zooplankton Patch Dynamics, Meng Zhou, Mark E. Huntley

Journal of Marine Research

A theory of zooplankton and micronekton patch dynamics is developed that expressly includes animal behavior. This represents a departure from traditional models of patch dynamics, which generally treat animals as Lagrangian particles whose distributions are determined solely by processes of advection and diffusion. The “bio-continuum” theory is based on principles of statistical mechanics, and describes animal aggregations in terms of mean motion, random motion, random kinetic energy, distribution and abundance. The forces on an animal aggregation act both upon the aggregation as a whole (external forces) or between individuals (internal forces). We demonstrate here that the internal forces which serve …

High-Frequency Baroclinic Wave Motions In An Equatorial Ocean Current And Related Temperature Fluctuations, Hong Ma

Journal of Marine Research

This paper uses a theoretical model to demonstrate the existence of a group of equatorially trapped, high-frequency (wave-periods shorter than one week), meso-to-small-scale (wave-lengths shorter than 100 km), baroclinic waves which are embedded in a geostrophic current with only vertical shear. Due to their relatively large vertical and meridional velocities, these high-frequency equatorial waves may play an important role in transporting momentum as well as heat energy in the vertical and transequatorial directions.

The Dynamics Of North Brazil Current Retroflection Eddies, Hong Ma

Journal of Marine Research

This paper applies analytical and numerical methods to study possible causes of the formation and translation of North Brazil Current retroflection eddies. It shows that the dynamic response of the equatorial western boundary of the Atlantic Ocean to either a remote forcing which is represented by an incoming Rossby wave packet that deepens the equatorial thermocline, or to the wind forcing over the tropical Atlantic Ocean can result in northwestward translating eddies up the coast of Brazil. The numerically simulated eddies closely resemble the features of the observed North Brazil Current retroflection eddies. The formation mechanism of these eddies has …

On Frontal And Ventilated Models Of The Main Thermocline, Simon Hood, Richard G. Williams

Journal of Marine Research

A new similarity approach is applied to the thermocline equations in order to examine contrasting frontal and ventilated models of the main thermocline. The method of solution involves reducing the number of independent variables of the controlling partial differential equation, leading to a particular form for the solutions which satisfy appropriate boundary conditions. A frontal model of the thermocline is obtained following the study of Salmon and Hollerbach (1991). When the vertical diffusivity becomes vanishingly small, an interior front in the subtropical gyre appears at the depth where the vertical velocity changes sign. The front separates downwelling warm water in …

Oxygen And Ph Regulation Of Protein Synthesis In Mitochondria From Artemia Franciscana Embryos, Kurt E. Kwast, Steven C. Hand

Faculty Publications

To identify factors responsible for the down-regulation of mitochondrial biosynthetic processes during anoxia in encysted Artemia franciscana embryos, the effects of oxygen limitation and pH on protein synthesis were investigated in isolated mitochondria. At the optimal pH of 7.5, exposure of mitochondria to anoxia decreases the protein synthesis rate by 79%. Rates were suppressed by a further 10% at pH 6.8, the intracellular pH (pH,) measured under anoxia in vivo. Matrix pH, measured under identical conditions, was 8.43 ± 0.01 at an extramitochondrial pH of 7.9 (mean ± S.E.M. n = 3), 8.05 ± 0.01 at pH 7.5, and 7.10 …

Carbohydrate Mobilization During Germination Of Post-Diapausing Gemmules Of The Freshwater Sponge Eunapius Fragilis, Stephen H. Loomis, Louis F. Ungemach, Bruce R. Branchini, Steven C. Hand, Paul E. Fell

Faculty Publications

Post-diapausing gemmules of the freshwater sponge Eunapius fragilis were found to contain sorbitol and glycogen as their primary carbohydrates. The sorbitol probably acts to increase the tolerance of the gemmules to freezing and desiccation. During germination, average sorbitol levels-measured as micromoles of sorbitol per gram of fresh weight of gemmule tissue (μmol/gfw)-declined from a control value of 36 μmol/gfw to about 4 μmol/gfw. Concomitantly, average glycogen levels increased from a control value of 29 μmol/gfw to a steady-state level of 62 μmol/gfw. It is probable that glycogen is being synthesized at the expense of sorbitol. The breakdown of sorbitol was …

Climate Forcing And Thermal Feedback Of Residual Lake-Ice Covers In The High Arctic, Peter T. Doran, Christopher P. Mckay, W. Peter Adams, Michael C. English, Robert A. Wharton, Michael A. Meyer

Faculty Publications

A discontinuous ice coverage and lake temperature record of 36-yr duration has been compiled for Colour Lake (79°25'N, 90°45'W) on Axel Heiberg Island, Northwest Territories. About once every 6 yr, the ice cover remains through the entire summer, creating a residual ice cover the following winter. Residual ice covers are more frequent in the last 10 yr (1986-1995) than in the 20 yr from 1959 to 1978, indicating a reduction in climate factors controlling ice decay. These factors are identified as the number of thawing degree-days, suggesting a tendency toward cooler summers over the last decade. We report year-round meteorology …

Categories And Culture: On The 'Rectification Of Names' In Comparative Law, Janet Ainsworth

Faculty Articles

This article proposes a thorough ‘rectification of names’ take place in comparative legal studies, with a specific focus on Chinese law. Pioneering Chinese comparative law scholars focused on describing the Chinese legal system using Western legal terminology. The job of the second-generation of legal scholars, however, is to interpret both the primary source material and prior interpretations. There are many pitfalls entailed with studying non-Western law, foremost is the danger of one’s conceptual paradigms influencing an interpretation. Any culture’s legal order is uniquely tuned to a cultural context, and Chinese culture represents a social order with sufficient coherence for scholars …

Children And Inheritance In The Nontraditional Family, Ralph C. Brashier

Utah Law Review

This Article has reviewed the current state of laws regarding the inheritance rights of children in the nontraditional family. It has, I hope (and yet regret), demonstrated that the laws are here, there, and everywhere in-between. And sometimes they are nowhere at all. It is clear that the efficient probate schemes that have served the traditional family for decades are ill equipped to address many of the problems that face its nontraditional counterpart. The overview provided here emphasizes the magnitude of those inheritance problems. Each of the subtopics addressed in this article-nonmarital children, adopted children, and children of reproductive technology-poses …

Reconsidering The Criteria For Legal Fatherhood, Leslie Joan Harris

Utah Law Review

For more than two decades scholars have advocated that adults who function as children's parents and develop emotional bonds with them be recognized as the children's legal parents, at least for purposes of custodial and related rights.' These proposals are based on the belief that a child's greatest need is for a close, stable relationship with an adult committed to the child's welfare, a position that is not particularly controversial today. With some exceptions, however, the law of parent-child relationships has not followed these recommendations. Instead, parental rights continue to be based mostly on biological parenthood or maxiage to one …

The results of the review indicate that cooperative learning is an effective and viable method of instruction today, which should continue to be used in the future.

Women Characters In The Plays By Tennessee Williams, Marina V. Zakharova

Graduate Research Papers

Tennessee Williams is one of the most important figures in American dramaturgy of the twentieth century. His drama expresses the main points of American contemporary culture. The complex dramatic world created by Williams consists of many levels and components. One of the fundamental themes on which Williams' theater is based is a theme of the dying "noble" tradition of the Southern life style and its conflict with the rigid and pragmatic modern world.

This conflict is presented from the point of view of action and characters as a conflict between reality and illusion, the collision of sensitive and brutal and …

Mitochondrial Dna Variation In Screwworm, David B. Taylor, Allen L. Szalanski, Richard D. Peterson Ii

Department of Entomology: Faculty Publications

Polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) analysis was used to characterize mitochondrial DNA (mtDNA) variation in screwworms, Cochliomyia hominivorax, and secondary screwworm, C. macellaria, from the Caribbean, North America and South America. Four amplicons, totaling 7.1 kb, were analysed with sixteen restriction enzymes. A total of 133 restriction sites was observed in the two species, 104 in C. hominivorax, of which nineteen were variable, and ninety-five in C. macellaria, none of which was variable. Fourteen mtDNA haplotypes were observed among eighteen C. hominivorax examined. Mean divergence between C. hominivorax haplotypes (d) was 0.0064 …

Oviposition And Calling Behavior Of Codling Moth (Lepidoptera: Tortricidae) In The Presence Of Codlemone, Thomas J. Weissling, Alan L. Knight

Department of Entomology: Faculty Publications

The effect of the major component of codling moth, Cydia pomonella (L.) sex pheromone (codlemone, E,E-8,10-dodecadien-l-ol) on female calling and oviposition behavior was investigated. Calling by virgin females was similar between moths placed in sealed containers containing codlemone or codlemone-free air. However, when pheromone emitted by females was removed by a continuous air stream, calling in codlemone-permeated air was significantly higher than in clean air. The temporal pattern of calling was unaltered by the presence of codlemone. In a laboratory no-choice test, oviposition rates by codling moth females were similar in the presence of codlemone and in codlemone-free air. However, …

Molecular Differentiation Of Alfalfa Weevil Strains (Coleoptera: Curculionidae), S. J. Erney, K. P. Pruess, S. D. Danielson, T. O. Powers

Department of Entomology: Faculty Publications

Mitochondrial DNA was amplified and sequenced from eastern, western, and Egyptian strains of alfalfa weevil, Hypera postica (Gyllenhal). Eastern and Egyptian weevils differed at only 2 nucleotide sites in 1,031 base pairs sequenced; western weevils differed by 5% sequence divergence. Three restriction sites were identified which separated eastern and western haplotypes. No intrastrain polymorphism was detected in 150 weevils from Nebraska. Collections from Lincoln in eastern Nebraska and Scottsbluff in western Nebraska were fixed for the eastern and western haplotypes, respectively. Eastern and western haplotypes were found together in the same fields in a broad overlap region in central Nebraska.
