Wyoming’S Ucross Ranch: Its Birds, History, And Natural Environment, Jacqueline Lee Canterbury, Paul Johnsgard 2019 University of Nebraska Lincoln

Wyoming’S Ucross Ranch: Its Birds, History, And Natural Environment, Jacqueline Lee Canterbury, Paul Johnsgard

Zea E-Books

This book profiles 60 of the most abundant, characteristic, and interesting birds that have been regularly reported from the Ucross Ranch and the adjacent Powder River Basin. The 20,000-acre Ucross Ranch lies on the western edge of the Powder River Basin of northeastern Wyoming. Ucross is a textbook example of the prairie grassland/ shrubland habitat type referred to as the sagebrush steppe, a landscape that is an icon of Wyoming’s vast open spaces. We focus especially on those species that occur year-round or are present as breeders during the summer months, and we place emphasis on a unique ...


A Pilot Study Of The Effects Of Mycoplasma Ovipneumoniae Exposure On Domestic Lamb Growth And Performance, Thomas E. Besser, Jessica Levy, Melissa Ackerman, Danielle Nelson, Kezia Manlove, Kathleen A. Potter, Jan Busboom, Margaret Benson 2019 Washington State University

A Pilot Study Of The Effects Of Mycoplasma Ovipneumoniae Exposure On Domestic Lamb Growth And Performance, Thomas E. Besser, Jessica Levy, Melissa Ackerman, Danielle Nelson, Kezia Manlove, Kathleen A. Potter, Jan Busboom, Margaret Benson

Wildland Resources Faculty Publications

Mycoplasma ovipneumoniae is a globally distributed pathogen that has been associated with pneumonia in both domestic and wild Caprinae. It is closely related to M. hyopneumoniae, a respiratory pathogen of swine that is associated with decreased growth rates of pigs as well as clinical respiratory disease. In order to assess the effects of M. ovipneumoniae on lamb performance, we generated a cohort of lambs free of M. ovipneumoniae by segregation of test negative ewes after lambing, then compared the growth and carcass quality traits of M. ovipneumoniae-free and -colonized lambs from weaning to harvest. Some signs of respiratory disease ...


Estimability Of Migration Survival Rates From Integrated Breeding And Winter Capture–Recapture Data, Clark S. Rushing 2019 Utah State University

Estimability Of Migration Survival Rates From Integrated Breeding And Winter Capture–Recapture Data, Clark S. Rushing

Ecology Center Publications

Long‐distance migration is a common phenomenon across the animal kingdom but the scale of annual migratory movements has made it difficult for researchers to estimate survival rates during these periods of the annual cycle. Estimating migration survival is particularly challenging for small‐bodied species that cannot carry satellite tags, a group that includes the vast majority of migratory species. When capture–recapture data are available for linked breeding and non‐breeding populations, estimation of overall migration survival is possible but current methods do not allow separate estimation of spring and autumn survival rates. Recent development of a Bayesian integrated ...

Analyzing Chlorophyll-a (Chl-a) from Moderate Resolution Imaging Spectroradiomerer (MODIS) data after Penglai oil spills on 4 June 2011, found a bloom with peak value of Chl-a (13.66 mg m−3) spread over an area of 800 km2 during 18–25 June 2011, and a pronounced increase in the monthly Chl-a concentration (6.40 mg m−3) on June 2012 in the Bohai Sea. Out of the 21 oil spills, 14 blooms were observed, while 11 ...


Geospatial Modeling Of Land Cover Change In The Chocó-Darien Global Ecoregion Of South America; One Of Most Biodiverse And Rainy Areas In The World, José Camilo Fagua, R. Douglas Ramsey 2019 Utah State University

Geospatial Modeling Of Land Cover Change In The Chocó-Darien Global Ecoregion Of South America; One Of Most Biodiverse And Rainy Areas In The World, José Camilo Fagua, R. Douglas Ramsey

Ecology Center Publications

The tropical rain forests of northwest South America fall within the Chocó-Darien Global Ecoregion (CGE). The CGE is one of 25 global biodiversity hotspots prioritized for conservation due to its high biodiversity and endemism as well as threats due to deforestation. The analysis of land-use and land-cover (LULC) change within the CGE using remotely sensed imagery is challenging because this area is considered to be one of the rainiest places on the planet (hence high frequency of cloud cover). Furthermore, the availability of high-resolution remotely sensed data is low for developing countries before 2015. Using the Random Forest ensemble learning ...


Back To The Future: Conserving Functional And Phylogenetic Diversity In The Amphibian-Climate Refuges, Ricardo Lourenço-de-Moraes, Felipe S. Campos, Rodrigo B. Ferreira, Mirco Solé, Karen H. Beard, Rogério P. Bastos 2019 Universidade Estadual de Maringá

Back To The Future: Conserving Functional And Phylogenetic Diversity In The Amphibian-Climate Refuges, Ricardo Lourenço-De-Moraes, Felipe S. Campos, Rodrigo B. Ferreira, Mirco Solé, Karen H. Beard, Rogério P. Bastos

Ecology Center Publications

Climate refuges have been used by several species over historical climate change. Ectothermic species often display good models for climate change studies because they are highly sensitive to temperature. Analysis of species loss with ecosystem and evolutionary values helps to understand environmental processes and climate change consequences. We determined the functional and phylogenetic diversity of amphibians in the Atlantic Forest hotspot, using multiple models representing present and future conditions. Through a novel approach, we predict species’ threat status by 2080, following the IUCN’s criterion B1. Our results estimate a drastic reduction in species richness, ecosystem functioning and evolutionary history ...

Wildland Resources Faculty Publications

Anthropogenic infrastructure can negatively affect wildlife through direct mortality and/or displacement behaviors. Some tetranoids (grouse spp.) species are particularly vulnerable to tall anthropogenic structures because they evolved in ecosystems void of vertical structures. In western North America, electric power transmission and distribution lines (power lines) occur in sagebrush (Artemisia spp.) landscapes within the range of the greater sage-grouse (Centrocercus urophasianus; sage-grouse). The U.S. Fish and Wildlife Service recommended using buffer zones near leks to mitigate the potential impacts of power lines on sage-grouse. However, recommended buffer distances are inconsistent across state and federal agencies because data are lacking ...


Climate Change Adaptation In The Delta Nile Region Of Egypt: Implications For Agricultural Extension, Hazem S. Kassem, Abdel Raouf Suleiman Bello, Bader M. Alotaibi, Fahd O. Aldosri, Gary S. Straquadine 2019 King Saud University

Climate Change Adaptation In The Delta Nile Region Of Egypt: Implications For Agricultural Extension, Hazem S. Kassem, Abdel Raouf Suleiman Bello, Bader M. Alotaibi, Fahd O. Aldosri, Gary S. Straquadine

Extension Research

This study used quantitative and qualitative methods to collect data, using questionnaires and interviews, from 792 randomly-selected farmers in two of the governorates in the Nile Delta Region, Egypt. A workshop was organized for 59 extension professionals working in the two governorates, looking at how the adaptive capacity of the agricultural sector towards climate change was being guided by policy-makers. Two focus groups were used: one with senior officials from the regional governorates and the other with central government administrators from the Ministry of Agriculture and Land Reclamation. The study findings suggested that 51.9% of the investigated farmers at ...

Recoupling Fire And Grazing Reduces Wildland Fuel Loads On Rangelands, Heath D. Starns, Samuel D. Fuhlendorf, R. Dwayne Elmore, Dirac Twidwell, Eric T. Thacker, Torre J. Hovick, Barney Luttbeg

Wildland Resources Faculty Publications

Fire suppression and exclusion, the historically dominant paradigm of fire management, has resulted in major modifications of fire-dependent ecosystems worldwide. These changes are partially credited with a recent increase in wildfire number and extent, as well as more extreme fire behavior. Fire and herbivory historically interacted, and research has shown that the interaction creates a unique mosaic of vegetation heterogeneity that each disturbance alone does not create. Because fire and grazing have largely been decoupled in modern times, the degree to which the interaction affects fuels and fire regimes has not yet been quantified. We evaluated effects of fire-only and ...

Intensification Of The Decadal Activity In Equatorial Rossby Waves And Linkage To Changing Tropical Circulation, Wan-Ling Tseng, Shih-Yu (Simon) Wang, Huang-Hsiung Hsu, Jonathan D.D. Meyer

Plants, Soils, and Climate Faculty Publications

Equatorial Rossby waves (ERWs) are manifest as westward-propagating, planetary-scale waves that feature a symmetric pair of pressure and zonal wind fields about the equator. ERWs can modulate tropical convective activity, especially in South Asia and the Maritime Continents, and represent an important mode of intraseasonal variability additional to the Madden-Julian Oscillation. Changes in the frequency and intensity of ERWs during the recent decades were investigated based on observations of tropospheric winds and tropical convection. Spectral analyses indicated that ERWs appear to have intensified especially in the upper troposphere; this is associated with increased convective activity located off the equator. The ...


Concept Inventories As A Resource For Teaching Evolution, Robert E. Furrow, Jeremy L. Hsu 2019 University of California, Davis

Concept Inventories As A Resource For Teaching Evolution, Robert E. Furrow, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Understanding evolution is critical to learning biology, but few college instructors take advantage of the body of peer-reviewed literature that can inform evolution teaching and assessment. Here we summarize the peer-reviewed papers on tools to assess student learning of evolutionary concepts. These published concept inventories provide a resource for instructors to design courses, gauge student preparation, identify key misconceptions in their student population, and measure the impact of a lesson, course, or broader curriculum on student learning. Because these inventories vary in their format, target audience, and degree of validation, we outline and explain these features. In addition to summarizing ...

International Crisis and Risk Communication Conference

This study examines the role of traditional versus new media’s impact on citizens’ perceptions of risk within elder care. We analyzed survey data from 112 Slovak citizens regarding their social network activity and perceptions of corruption, ageism, and health disparities in the Slovak elder care system. Previous research (Lukacovic, Sellnow-Richmond, & Durechova, under contract) identified three prominent sociopolitical issues present in the Slovak medical system among Slovak UGC discourse regarding Slovak healthcare inequity: corruption, threats to dignity, and discrimination. Here, we examined the extent to which social media users perceive the prevalence and subsequent risk of experiencing health disparities within ...


Detection Of Adsorbed Chlordecone On Microplastics In Marine Sediments In Guadeloupe: A Preliminary Study, Fidji Sandre, Charlotte R.

Detection Of Adsorbed Chlordecone On Microplastics In Marine Sediments In Guadeloupe: A Preliminary Study, Fidji Sandre, Charlotte R. Dromard, Karyn Le Menach, Yolande Bouchon-Navaro, Sébastien Cordonnier, Nathalie Tapie, Hélène Budzinski, Claude Bouchon

Gulf and Caribbean Research

Plastic pollution in the oceans is recognized as a worldwide problem. Since the 1950s, the production of plastics has been increasing and the first reports of microplastics (particles < 500 μm) in the marine environment began to appear in the 1970s. These particles represent a growing environmental problem due to their dispersion in seawater and marine organisms. Additionally, microparticles in general can adsorb pollutants that will then become bioavailable to organisms by being desorbed during digestion, which could be an important pathway for the contamination of organisms. In Guadeloupe and Martinique, an organochlorine pesticide called “chlordecone” was used from 1972 to 1993 in banana plantations and this very persistent pollutant contaminates soils, rivers, and coastal marine areas and accumulates in marine foodwebs. To examine these issues, we had two goals: 1) to assess the contamination of marine sediments by microplastics surrounding Guadeloupe; and 2) to determine the ability of microplastics to adsorb chlordecone, as has been demonstrated for other organochlorine pollutants. To do so, marine sediments were collected in triplicate from 12 sites in coral reef environments around the island. Microplastics from each sample were then enumerated by size, color and shape under a binocular microscope. The results indicate that microplastics are found in all the studied sites and that their distribution could be linked to marine currents or proximity to areas of significant human activities (port activities, agglomeration, etc.). Finally, our preliminary results indicated that chlordecone could be adsorbed onto microplastics, with a concentration ranging from 0.00036—0.00173 µg/µg of microfilter.


Ecopedagogy: Learning How To Participate In Ecological Consciousness, Peterson, Eric 2019 California Institute of Integral Studies

Ecopedagogy: Learning How To Participate In Ecological Consciousness, Peterson, Eric

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

This paper is the result of an inquiry into ecological consciousness through a participatory paradigm. The dialectical relationship between institutionalized education and consciousness is central to this inquiry’s focus. This exploration into ecological consciousness has lead to the following question: How can institutionalized education be designed, delivered, and experienced in a way that nurtures ecological intelligence, ecological consciousness, and more importantly, ecological activism? The ‘sense of self ‘is a central theme within the paper, and led to the conception of intraearthal and interearthal relationships as a way of communicating our need to identify as being in Earth. The author ...


Psychotherapy In The Dream: A Phenomenological Exploration, Bustos, Nick 2019 California Institute of Integral Studies

Psychotherapy In The Dream: A Phenomenological Exploration, Bustos, Nick

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

Post-materialist ontologies offer a transformed worldview whose implications point toward the illusory nature of the separate self, or ego. Aligned with the literature of mysticism and perennialist spiritual models, this portends a significantly altered backdrop for the practice and discipline of psychotherapy, the underlying premises of which assume a strict existential dichotomy between patient and therapist. Kenneth Wapnick, preeminent scholar of the twentieth-century spiritual document of A Course in Miracles, provides a relevant model toward integrating spiritually-based, ego-negative states within psychotherapy practice. The author studied the lived experiences of eight psychotherapists, both practicing and retired, who practice according to this ...


Categorical Modelling Of Conscious States, Baruss, Imants 2019 California Institute of Integral Studies

Categorical Modelling Of Conscious States, Baruss, Imants

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

In the last several decades, there has been an explosion of research concerning consciousness with some efforts at mathematical modelling. The purpose of this paper is to model conscious states using categorical constructions. In particular, this modelling captures temporality, the intentional structure of consciousness, and meaning fields, which provide the templates for occurrent events. The architecture of conscious states naturally lends itself to applications of category theory, more specifically to sheaf-like constructions in which the stacks over a site are topoi whose germs are the objects of the topoi. Each topos represents the potential experiential content of an individual where ...


Oneness In Everyday Life: Nonduality, Wholeness And Human Life After Awakening, Gibbons, Tom 2019 California Institute of Integral Studies

Oneness In Everyday Life: Nonduality, Wholeness And Human Life After Awakening, Gibbons, Tom

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

In Advaita Vedanta a distinction is made between an experience of oneness and permanent awakening. The author argues that a nondual philosophy such as Advaita - as opposed to a direct experience of oneness – contains significant theoretical difficulties, which in turn are reflected in problems with actualizing nonduality in everyday human life. Alternative spiritual conceptions that might be more helpful in guiding the nondual aspirant in her spiritual life are examined, including the concept of “wholeness.” In the place of a reliance on an exclusive doctrine of nonduality, Jorge Ferrar’s concept of “Participatory Spirituality” and A. H. Almaas’s idea ...

Appalachian Economic Futures, Dewayne Barton, John Deskins, Paul Corbit Brown, William Hal Gorby, Jill Moles Mullins, Nicholas F. Stump, Matt Winans, Brenden E. Mcneil, Eloise Elliott, Chris Haddox, E Gordon Gee, Eddie Brzostek, Audra Slocum, Trevor Mckenzie, Tom Hansell

Exhibit Panels

When people talk about the future of Appalachia, they typically mean economic futures: What will happen to coal jobs? How will Appalachia diversify its economy? What about poverty? Stereotypes about our region represent our people as disinterested in education, and hostile to innovation, technology, and sustainability. We see a different story. This part of the exhibit looks at ways that Appalachians are taking their strong sense of culture, their linguistic distinctiveness, and their relationship to the natural world to imagine new futures in diverse industries, sustainable practices, and stronger education systems.
