A History Of Woodland Dynamics In The Owyhee’S: Encroachment, Stand Closure, Understory Dynamics, And Tree Biomass, Rick Miller, Jaime Ratchford, Dustin Johnson Jan 2008

A History Of Woodland Dynamics In The Owyhee’S: Encroachment, Stand Closure, Understory Dynamics, And Tree Biomass, Rick Miller, Jaime Ratchford, Dustin Johnson

Reports

Piñon and juniper woodlands in the cold desert of the Intermountain West occupy over 44.6 million acres (Miller and Tausch 2001). These woodlands are commonly associated with sagebrush communities forming a mosaic of shrub-steppe and woodland across the region. Numerous studies have documented the recent expansion (since the late 1800’s) of these woodlands that has resulted in the replacement of shrub-steppe communities. Recent debate has challenged the degree of expansion in terms of percent of new areas occupied by trees and the increase in total population of piñon and juniper since the late 1800’s. Various interest groups have become concerned …

Accurate Mental Maps As An Aspect Of Local Ecological Knowledge (Lek): A Case Study From Lough Neagh, Northern Ireland, John Mckenna, Rory J. Quinn, Daniel J. Donnelly, J. Andrew G. Cooper Jan 2008

Accurate Mental Maps As An Aspect Of Local Ecological Knowledge (Lek): A Case Study From Lough Neagh, Northern Ireland, John Mckenna, Rory J. Quinn, Daniel J. Donnelly, J. Andrew G. Cooper

All UNF Research

A mental map of the substrate of Lough Neagh, Northern Ireland, compiled from interviews with local fishermen, is compared with maps produced by science-based techniques. The comparison reveals that the mental map is highly accurate. This finding contrasts with the spatial distortion characteristic of the classic mental map. The accuracy of the Lough Neagh map is attributed to the fact that it is a compendium of the knowledge of several generations, rather than an individual perception. Individual distortions are filtered out, and accuracy is promoted by economic self-interest. High accuracy may be characteristic of the mental maps held by artisanal …

Epistemological Pluralism: Reorganizing Interdisciplinary Research, Thaddeus R. Miller, Timothy D. Baird, Caitlin M. Littlefield, Gary Kofinas, F. Stuart Chapin, Iii, Charles L. Redman Jan 2008

Epistemological Pluralism: Reorganizing Interdisciplinary Research, Thaddeus R. Miller, Timothy D. Baird, Caitlin M. Littlefield, Gary Kofinas, F. Stuart Chapin, Iii, Charles L. Redman

All UNF Research

Despite progress in interdisciplinary research, difficulties remain. In this paper, we argue that scholars, educators, and practitioners need to critically rethink the ways in which interdisciplinary research and training are conducted. We present epistemological pluralism as an approach for conducting innovative, collaborative research and study. Epistemological pluralism recognizes that, in any given research context, there may be several valuable ways of knowing, and that accommodating this plurality can lead to more successful integrated study. This approach is particularly useful in the study and management of social–ecological systems. Through resilience theory's adaptive cycle, we demonstrate how a focus on epistemological pluralism …

Analogical Reasoning In The Engineering Design Process And Technology Education Applications, Jenny Daugherty, Nathan Mentzer Jan 2008

Analogical Reasoning In The Engineering Design Process And Technology Education Applications, Jenny Daugherty, Nathan Mentzer

Publications

This synthesis paper discusses the research exploring analogical reasoning, the role of analogies in the engineering design process, and educational applications for analogical reasoning. Researchers have discovered that analogical reasoning is often a fundamental cognitive tool in design problem solving. Regarding the possible role of analogical reasoning in the context of technology education; analogies may be a useful tool to develop student’s design skills, teach abstract or complex concepts, and build students’ analogical reasoning skills for general problem solving. The positive and negative educational implications of analogical reasoning being explored by researchers are also discussed.

Interactive Landuse Planning In Indonesian Rain-Forest Landscapes: Reconnecting Plans To Practice, Eva Wollenberg, Bruce Campbell, Edmond Dounias, Petrus Gunarso, Moira Moeliono, Douglas Sheil Jan 2008

Interactive Landuse Planning In Indonesian Rain-Forest Landscapes: Reconnecting Plans To Practice, Eva Wollenberg, Bruce Campbell, Edmond Dounias, Petrus Gunarso, Moira Moeliono, Douglas Sheil

All UNF Research

Indonesia’s 1999–2004 decentralization reforms created opportunities for land-use planning that reflected local conditions and local people’s needs. We report on seven years of work in the District of Malinau in Indonesian Borneo that attempted to reconnect government land-use plans to local people’s values, priorities, and practices. Four principles are proposed to support more interactive planning between government and local land users: Support local groups to make their local knowledge, experience, and aspirations more visible in formal land-use planning and decision making; create channels of communication, feedback, and transparency to support the adaptive capacities and accountability of district leadership and institutions; …

Design Of A Microscopy-Based Screening Method For Stomatal Development Genes In Arabidopsis Thaliana, Mercedes Tatiana Quinteros Perez Jan 2008

Design Of A Microscopy-Based Screening Method For Stomatal Development Genes In Arabidopsis Thaliana, Mercedes Tatiana Quinteros Perez

Master's Theses and Doctoral Dissertations

Stomata are microscopic pores in the epidermis of plants that regulate gas exchange and transpiration. Regulation of stomatal behavior offers opportunity for crop improvement; stomata are also useful for research into cell patterning, differentiation, and development. The purpose of this project was to create a reverse genetics, microscopy-based screening method to identify Arabidopsis genes important in guard cell development. It was hypothesized that gene coexpression analysis would facilitate identification of gene candidates involved in stomatal development. Plants harboring mutations in the candidate genes were analyzed to detect a stomatal phenotype, using dental resin impressions and light microscopy. Coexpression screening was …

Who Says So - Defining Cruel And Unusual Punishment By Science, Sentiment, And Consensus, Aimee Logan Jan 2008

Who Says So - Defining Cruel And Unusual Punishment By Science, Sentiment, And Consensus, Aimee Logan

UC Law Constitutional Quarterly

The 2003 United States Supreme Court decision Atkins v. Virginia provides a unique opportunity to discuss how the Court integrates science into its constitutional philosophy. In Atkins, a majority of the Court concluded that executing criminals with mental retardation violates the Eighth Amendments prohibition against cruel and unusual punishment. Psychologists, psychiatrists and others in the scientific community have studied mental retardation for some time. However, the tests they use, and the criteria they look at, do not necessarily translate to the criminal justice system. Thus, in order to give legal significance to mental retardation, the Supreme Court must operationally define …

Maintaining The Constitutionality Of The Patent System, Susanna Chenette Jan 2008

Maintaining The Constitutionality Of The Patent System, Susanna Chenette

UC Law Constitutional Quarterly

Congress' constitutional power to establish a patent system is not unrestrained. Rather, it is derived from a clause that expressly limits the reach of any patent system created by requiring it "to advance the progress of science and the useful arts." Inherent in any such system is the fundamental quid pro quo between society and inventor: an inventor receives an exclusive right for a limited time to his invention, and society benefits from the full disclosure of the inventor's knowledge, incentivizing research and dispersing knowledge. However, while this constitutional dictate remains unaltered, the patent system has grown and changed markedly …

Pathways To Patents: Applying The Written Description Requirement Doctrine To Patents On Biological Pathways, Shengfeng Chen Jan 2008

Pathways To Patents: Applying The Written Description Requirement Doctrine To Patents On Biological Pathways, Shengfeng Chen

UC Law SF Communications and Entertainment Journal

Research tool and "research-through" patents have become increasing concerns in recent years, particularly in pharmaceutical and biotechnology fields. In response to the impacts of these patents, courts have responded with a series of judicial decisions, and attempted to regulate these patents using the written description doctrine. However, these decisions have been confusing and inconsistent. After an examination of the Federal Circuit's written description jurisprudence and scholastic responses to these decisions, this article proposes a new standard of meeting the written description requirement to provide a workable solution for regulating research tool and "research-through" patents.

Proceedings Of The Tenth North American Crane Workshop: Cover, Preface, Contents Jan 2008

Proceedings Of The Tenth North American Crane Workshop: Cover, Preface, Contents

Proceedings of the North American Crane Workshop

Every 3 years (or thereabouts), the North American Crane Working Group holds a workshop for the exchange of information regarding efforts to conserve and better understand America’s two cranes. The papers herein, with a few exceptions, were presented in Zacatecas City, Zacatecas, Mexico 7-10 February 2006 at the Tenth North American Crane Workshop. When preparing for a trip to Mexico in February, visions of sunny beaches come first to mind. However the city of Zacatecas is over 8,000 feet above sea level, so nights were often chilly and the altitudinal changes took a while for us flatlanders to adjust to. …

A Wasting Syndrome In Released Whooping Cranes In Florida Associated With Infectious Bursal Disease Titers, Marilyn G. Spalding, Holly S. Sellers, Barry K. Hartup, Glenn H. Olsen Jan 2008

A Wasting Syndrome In Released Whooping Cranes In Florida Associated With Infectious Bursal Disease Titers, Marilyn G. Spalding, Holly S. Sellers, Barry K. Hartup, Glenn H. Olsen

Proceedings of the North American Crane Workshop

Whooping cranes (Grus americana) have been reintroduced into central Florida beginning in 1993 until the present. Bobcat predation of otherwise healthy cranes in good nutritional condition was the most common cause of mortality. However, release cohorts in the years 1997-1998 (14/22 died) and 2001-2002 (14/27 died, 5/27 clinical illness) experienced unusually high morbidity and mortality. Positive serum neutralizing titers for infectious bursal disease virus (IBDV) were identified following the 2001 event, and an epidemiological study of released birds and the captive source flocks was initiated. Serotype 1 (Lukert and Variant A) tests were mostly negative. Serotype 2 testing …

New Hunter Education Strategies To Protect Whooping Cranes In Texas And Kansas, Lee Ann Johnson Linam, Helen M. Hands, Jay Roberson Jan 2008

New Hunter Education Strategies To Protect Whooping Cranes In Texas And Kansas, Lee Ann Johnson Linam, Helen M. Hands, Jay Roberson

Proceedings of the North American Crane Workshop

The decline of the whooping crane (Grus americana) has often been attributed primarily to loss of habitat and overharvest. Although hunting of whooping cranes is now prohibited, shootings sometimes occur. Recent incidences have prompted the Texas Parks and Wildlife Department (Texas) and the Kansas Department of Wildlife and Parks (Kansas) to develop new strategies that increase hunter recognition of legal game species and awareness of endangered species concerns. Both agencies have produced or updated publications for goose and sandhill crane (Grus canadensis) hunters. Texas has developed video news releases for the general public and a video/DVD …

The Cuban Sandhill Crane As Umbrella Species: Relationship With Plant Diversity In Threatened White Sand Savannahs, Duniet Marrero Garcia, Jose A. Osorio, Xiomara Galvez Aguilera, Felipe Chavez-Ramirez Jan 2008

The Cuban Sandhill Crane As Umbrella Species: Relationship With Plant Diversity In Threatened White Sand Savannahs, Duniet Marrero Garcia, Jose A. Osorio, Xiomara Galvez Aguilera, Felipe Chavez-Ramirez

Proceedings of the North American Crane Workshop

This project describes relationships between the Cuban sandhill crane (Grus canadensis nesiotes) distribution and habitat use and plant diversity in white sand savannahs, a threatened ecosystem in Cuba. Data are based on habitat use and selection of 10 radio-tagged sandhill cranes in the Los Indios Ecological reserve, Isle of Youth. We used Arcview and satellite imagery to map broad vegetation categories. Within the general Pine-Palm savannahs specific plant communities were characterized using species composition and dominant plant life forms. Habitat types most used by cranes for feeding and nesting were also those with highest plant species richness and …

Temporal Dynamics And Flock Characteristics Of Sandhill Cranes In The Platte River Valley, Nebraska, Felipe Chavez-Ramirez Jan 2008

Temporal Dynamics And Flock Characteristics Of Sandhill Cranes In The Platte River Valley, Nebraska, Felipe Chavez-Ramirez

Proceedings of the North American Crane Workshop

I gathered information on crane flocks in the Platte River Valley during spring staging of 2002-2004. The objective of
this work was to evaluate hypotheses regarding flock size and formation using sandhill crane (Grus canadensis) flocks observed in
the Platte River Valley. Specifically, I wanted to: (a) evaluate the effect of period of migration, geographical location, and habitat
type on flock size, and (b) evaluate predictions regarding ecological theories of flock formation and behavior based on concentrated
resources, accessibility, social facilitation, and potential predation response. Flock size overall was influenced negatively by period
of migration (P < 0.001) and positively by geographical location (P < 0.01). Total crane abundance (55%) of flocks were located
in corn fields, but …
