A Quantitative Study Of Styles And Achenes Of Terminal And Basal Flowers Of Schoenoplectus Hallii (Cyperaceae), A Rare Plant Species Of Transient Wetland Habitats, Marian Smith, Sara Ammann, Nancy Parker, Paige Mettler-Cherry Nov 2006

A Quantitative Study Of Styles And Achenes Of Terminal And Basal Flowers Of Schoenoplectus Hallii (Cyperaceae), A Rare Plant Species Of Transient Wetland Habitats, Marian Smith, Sara Ammann, Nancy Parker, Paige Mettler-Cherry

Faculty Scholarship

Schoenoplectus hallii (A. Gray) S.G. Smith (Cyperaceae), a rare plant restricted to wetland habitats, is of conservation concern throughout its range. Taxonomy of the species recently has been clarified; however, quantitative descriptions of achene and flower morphology are incomplete and life history information is lacking. Because of its scarcity and the transient nature of populations, any large-scale study of the species will require the recovery of achenes from bulk soil samples and the identification and separation of the dimorphic achenes. The objectives of this study were to separate, identify and photograph the two achene types; to quantify the size and …


Potential Factors Influencing Nest Defense In Diurnal North American Raptors, Joan L. Morrison, Madeline Terry, Patricia L. Kennedy Jun 2006

Potential Factors Influencing Nest Defense In Diurnal North American Raptors, Joan L. Morrison, Madeline Terry, Patricia L. Kennedy

Faculty Scholarship

Nesting habitat, predator type, and level of reproductive effort influence nest defense behaviors in many bird species, yet no study has examined these or other possible factors influencing nest defense in a cross-species comparison for raptors. Using data from the literature, we grouped the nest defense behaviors of 19 diurnal North American raptors into four categories based on a gradient of aggressiveness. For each species, we identified the cover types where nesting occurred, accessibility of nest location, assessed two indices of reproductive effort, and examined associations between these factors and nest-defense behavior. We also we examined responses by raptor species …


The Scarlet Gene: Behavioral Genetics, Criminal Law, And Racial And Ethnic Stigma, Karen H. Rothenberg, Alice Wang Mar 2006

The Scarlet Gene: Behavioral Genetics, Criminal Law, And Racial And Ethnic Stigma, Karen H. Rothenberg, Alice Wang

Faculty Scholarship

Imagine that a scientist from the state university asks you and your family to participate in a study on a particular gene variant associated with alcoholism. The project focuses on your ethnic group, the Tracy Islanders, who have a higher incidence of alcoholism, as well as a higher incidence of the gene variant, than the general population. You will not be informed whether you have the gene variant, but your participation in the study might help scientists develop drugs to help individuals control their addiction to alcohol. You have a family history of alcoholism, and you are concerned that your …

The Complex Links Between Governance And Biodiversity, C. Barrett, C. Gibson, B. Hoffman, Mathew D. Mccubbins Jan 2006

The Complex Links Between Governance And Biodiversity, C. Barrett, C. Gibson, B. Hoffman, Mathew D. Mccubbins

Faculty Scholarship

We argue that two problems weaken the claims of those who link corruption and the exploitation of natural resources. The first is conceptual. Studies that use national level indicators of corruption fail to note that corruption comes in many forms, at multiple levels, and may or may not affect resource use. Without a clear causal model of the mechanism by which corruption affects resources, one should treat with caution any estimated relationship between corruption and the state of natural resources. The second problem is methodological: Simple models linking corruption measures and natural resource use typically do not account for other …


Behavioural Genetics In Criminal Cases: Past, Present And Future, Nita A. Farahany, William Bernet Jan 2006

Behavioural Genetics In Criminal Cases: Past, Present And Future, Nita A. Farahany, William Bernet

Faculty Scholarship

Researchers studying human behavioral genetics have made significant scientific progress in enhancing our understanding of the relative contributions of genetics and the environment in observed variations in human behavior. Quickly outpacing the advances in the science are its applications in the criminal justice system. Already, human behavioral genetics research has been introduced in the U.S. criminal justice system, and its use will only become more prevalent. This essay discusses the recent historical use of behavioral genetics in criminal cases, recent advances in two gene variants of particular interest in the criminal law, MAOA and SLC6A4, the recent expert testimony on …

The tetra-anionic form of ATP (ATP4-) is known to induce monovalent and divalent ion fluxes in cells that express purinergic P2X7 receptors (Steinberg et al., 1987; Sung et al., 1985), and with sustained application of ATP it has been shown that dyes as large as 831 daltons can permeate the cell membrane (Steinberg et al, 1987). The current study explores the kinetics of loading α,α-trehalose (342 daltons) into ATP stimulated J774.A1 cells, which are known to express the purinergic P2X7 receptor (Steinberg et al., 1987). Cells that were incubated at 37 ̊C in a 50 mM phosphate buffer (pH 7.0) …
