Islas De Las Californias, Colaboración Botánica: Islands Of The Californias Botanical Collaborative, William Hoyer, John Knapp, Denise Knapp, David Mazurkiewicz, Ken Owen, Luciana Luna-Mendoza, Kathryn Mceachern

Western North American Naturalist

After nearly 2 centuries of being negatively impacted, primarily by introduced mainland vertebrates, the unique flora and vegetation of the Islands of the Californias archipelago have been severely degraded. The botanical conservation challenges that lie ahead include the near extinction or extirpation of rare, endemic, and even common plant taxa; invasion of nonnative plants; near loss of unique island vegetation communities; and the degradation of a host of sites. These challenges are too large for any one entity to remedy alone. Many of the botanical resources impacted are found on multiple islands and cross political boundaries. The Islands of the …

Bats Of The California Channel Islands: New Records With New Methods, Patricia E. Brown, William E. Rainey

Western North American Naturalist

Eight bat species were known and documented from the California Channel Islands when J.C. Von Bloeker (1967) presented at the First California Islands Symposium in 1965. Additional bat surveys by P.E. Brown (1980) in the 1970s resulted in “Distribution of bats of the California Channel Islands,” which was presented at the second symposium in 1978. Methods of detecting and identifying bats have changed over the past century. Museum collection methods using shotguns have been replaced by mist-netting and recording of echolocation calls. Currently, capture or acoustic records have identified 14 bat species (56% of the 25 species known to occur …

Informing Our Successors: What Botanical Information For Santa Cruz Island Will Researchers And Conservation Managers In The Century Ahead Need The Most?, John M. Randall, Kathryn Mceachern, John Knapp, Paula Power, Steve Junak, Kristina Gill, Denise Knapp, Matt Guilliams

Western North American Naturalist

Climate changes are predicted to drive changes in plant species composition and vegetation cover around the world. Preserved specimens and other botanical information that we gather today—a period future practitioners may look back on as an early stage of modern anthropogenic climate change—will be of value to conservation managers and conservation biologists in the decades and centuries ahead. Here, we present suggestions for the systematic collection, long-term curation (in museums, herbaria, and other research institutions), and maintenance of plant specimens, along with associated data and analyses on the plants and vegetation present today and in the past. The primary aim …

Long-Term Monitoring Of Scripps's Murrelet And Guadalupe Murrelet At San Clemente Island, California: Evaluation Of Baseline Data In 2012–2016, Darrell L. Whitworth, Harold R. Carter, Michael W. Parker, Franklin Gress, Melissa Booker

Western North American Naturalist

San Clemente Island (SCI) supports one of the smallest Scripps’s Murrelet (Synthliboramphus scrippsi; SCMU) colonies in the world, and perhaps the only colony of Guadalupe Murrelets (S. hypoleucus; GUMU) in California. In 2012–2016, the U.S. Navy sponsored development of a long-term murrelet monitoring program at SCI that utilized nocturnal spotlight surveys, night-lighting at-sea captures, and nest monitoring. Standardized spotlight survey transects were established in nearshore waters off breeding areas at Seal Cove and southeast SCI (SESCI). Baseline mean spotlight counts were 29 ± 15 murrelets (n = 31) at Seal Cove in 2013–2016 and 21 ± 10 …

Avian And Skunk Predation Of Ashy Storm-Petrels At Santa Cruz Island, California, William R. Mciver, Harold R. Carter, A. Laurie Harvey, David M. Mazurkiewicz, Jim A. Howard, Paige L. Martin, John W. Mason

Western North American Naturalist

Avian and mammalian predation of Ashy Storm-Petrels (Oceanodroma homochroa) were documented during monthly nest monitoring in 1995–1998 and 2005–2015 and once-per-year monitoring in 1999–2004 at 5 colonies at Santa Cruz Island, California. Throughout the study period, predation by Barn Owls (Tyto alba) was documented at the sea cave colonies, and at Orizaba Rock, and likely contributed to reduced breeding success at Bat Cave in 1995–1997. Recent predation by Common Ravens (Corvus corax) caused reduced breeding success each year in 2012–2015 at Orizaba Rock (35%–48%) and in 2013 and 2015 at Bat Cave (49%–52%). Raven …

Status Of Ashy Storm-Petrel Breeding Colonies At Santa Cruz Island, California, 1912–1998, Harry R. Carter, William R. Mciver, Gerard J. Mcchesney, Darrell L. Whitworth, John R. Gilardi

Western North American Naturalist

We summarized historical knowledge from 1912 to 1998 of 13 known breeding colonies of Ashy Storm-Petrels (Oceanodroma homochroa) at Santa Cruz Island, California. Breeding was first reported by naturalists at Painted Cave (1912), Scorpion Rocks (1928), and Orizaba Rock (1937). During early seabird colony surveys of the Channel Islands, breeding was also noted at Cavern Point Cove Caves (1970), Diablo Rocks (1976), and Gull Island (1977). During 1991–1998, more extensive surveys of nearly all sea caves and offshore rocks documented additional breeding at Bat Cave, Cave of the Birds’ Eggs, Del Mar Cove Cave, Del Mar Rock, Dry …

Scripps's Murrelet At San Miguel Island, California: Status Of A Small Population At The Northwest Limit Of The Breeding Range, Darrell L. Whitworth, Harry R. Carter

Western North American Naturalist

San Miguel Island (SMI) and its adjacent islets, Prince Island and Castle Rock, support a small population of Scripps’s Murrelets (Synthliboramphus scrippsi) at the northwest limit of their breeding range. In 1994–1996, 2004, 2007, and 2015, we conducted at-sea surveys and nest searches to determine the breeding distribution and population size of the Scripps’s Murrelet at the SMI group. During at-sea vocal surveys in 1994–1996, murrelet calls were heard at 4 stations around Prince Island (43–167 calls), 2 stations off Castle Rock (6 calls and 80 calls), and 4 stations off northeast SMI (5–123 calls), but none were …

Examining Livelihoods Shifts Due To Sea-Level Rise Via The Midas (Migration, Intensification, And Diversification As Adaptive Strategies) Model, Andrew Bell

International Congress on Environmental Modelling and Software

Among the myriad impacts of sea-level rise, one set of impacts on livelihoods relates to the shift in freshwater, brackish water, and saltwater agriculture that will be possible in coastal areas. In South and Southeast Asia, Bangladesh and Vietnam are notable in particular for the growth of shrimp aquaculture as an adaptation to changes in salinity. However, while Vietnam has developed a clear and well-attended system of agro-ecological zoning, Bangladesh’s management of salinity is less developed. Conflicts arise among farmers sharing surface water systems over the use of sluice gates and the flow of fresh or salty water, with many …

Simulating Dynamic Drought Adaptation Behaviour Of Agricultural Stakeholders Using Agent-Based Models, Marthe Wens, Mike Johnson

International Congress on Environmental Modelling and Software

Increasing climate variability and changing socio-economic conditions are expected to exacerbate agricultural drought risk in many parts of the world. Current risk assessments, however, do not elegantly incorporate emergent adaptation strategies and therefore fall short in their representation of vulnerability dynamics. Adopting a socio-hydrological framework allows modelers to simultaneously consider the temporal and spatial extents of meteorological and hydrological factors and dynamic human behavior. In our research, we use spatially-explicit agent-based models to investigate how humans respond to perceived drought risk and ultimately impact the hydrological system, in hopes of deriving a clearer understanding of future agricultural drought risk. Agent-based …

An Agent-Based Approach To Evaluating Sustainable Drought Adaptation Policy, Mike Johnson, Marthe Wens

International Congress on Environmental Modelling and Software

Droughts are an increasingly prevalent and costly hazard that impact urban populations, agricultural production, and natural ecosystems. As climate becomes more variable, drought-prone regions are working to adapt through policy measures that address the diverse needs of urban centers, irrigation districts, farmers, governments, and NGOs. Developing policy pathways is a useful way to design such drought policies, however, their development requires an understanding of how human and biophysical systems interact and respond to a variety of climate and policy scenarios. In our research, we link a distributed hydrologic model with an agent based model to simulate the emergent, heterogeneous drought …

Examining The Impact And Influence Of The Leisure Science Literature, Mat D. Duerden, Michael B. Edwards, Michael C. Goates, Justin Dyer

Faculty Publications

This study explored the impact and influence of the leisure sciences literature through an analysis of highly cited articles. Discriminant function analysis identified whether articles had more exclusive impact inside or outside the field. Research themes and methodologies were examined based on these classifications. Results indicate articles with the greatest impact within the leisure literature tended to be quantitative studies drawing upon survey data and non-experimental designs focused on general leisure and outdoor/forest recreation. Articles with the greatest impact outside the leisure literature were more recent and focused on place attachment, psychological motivation, or community parks and recreation and used …

Borscht, Bliny, And Burritos: The Benefits Of Peer-To-Peer Experiential Learning Through Food, Naomi Caffee, Colleen Lucey

Russian Language Journal

Like other disciplines in the humanities, Russian Studies faces an ongoing crisis of recruiting and retaining majors and minors for the longevity of undergraduate programs (Looney and Lusin 2018). Shrinking budgets and limited resources compound the problem as language and culture departments across the United States are asked to do more with fewer resources (Gerber 2015). In the context of an increasingly corporatized academy where language and cultural studies are marginalized, faculty in Russian Studies have a powerful means at their disposal to attract new students and build cross-campus alliances: the common language of food. Courses on foodways can reinvigorate …

Ion Trajectory Simulations And Design Optimization Of Toroidal Ion Trap Mass Spectrometers, Jessica Marie Higgs

Theses and Dissertations

Ion traps can easily be miniaturized to become portable mass spectrometers. Trapped ions can be ejected by adjusting voltage settings of the radiofrequency (RF) signal applied to the electrodes. Several ion trap designs include the quadrupole ion trap (QIT), cylindrical ion trap (CIT), linear ion trap (LIT), rectilinear ion trap (RIT), toroidal ion trap, and cylindrical toroidal ion trap. Although toroidal ion traps are being used more widely in miniaturized mass spectrometers, there is a lack of fundamental understanding of how the toroidal electric field affects ion motion, and therefore, the ion trap's performance as a mass analyzer. Simulation programs …

The Administrative History Of San Miguel Island: The National Park Service On San Miguel From 1963 To 2016, Ian Williams, Mike Hill, Rob Danno, Reed Mccluskey, Mike Maki, Bill Ehorn, Ann Huston

Western North American Naturalist

In 2013, retired Park Ranger Mike Hill proposed writing the administrative history of the National Park Service (NPS) on San Miguel Island. An administrative history is the agency history of the NPS at a particular park, or in this case, on a particular island. Toward that end, 5 of the park rangers who have served as San Miguel Island Ranger gathered on that island in November 2013, along with former Superintendent Bill Ehorn and Chief of Cultural Resources Ann Huston. They reflected on years spent on San Miguel and recorded oral history interviews about those times.

Taxonomic And Compositional Differences Of Ground-Dwelling Arthropods In Riparian Habitats In Glen Canyon, Arizona, Usa, Barbara E. Ralston, Neil S. Cobb, Sandra L. Brantley, Jacob Higgins, Charles B. Yackulic

Western North American Naturalist

The disturbance history, plant species composition, productivity, and structural complexity of a site can exert bottom-up controls on arthropod diversity, abundance, and trophic structure. Regulation alters the hydrology and disturbance regimes of rivers and affects riparian habitats by changing plant quality parameters. Fifty years of regulation along the Colorado River downstream of Glen Canyon Dam has created a no-analog, postdam “lower” riparian zone close to the water’s edge that includes tamarisk (Tamarix sp.), a nonnative riparian shrub. At the same time, the predam “upper” facultative riparian zone has persisted several meters above the current flood stage. In summer 2009, …

Desorption Electrospray Ionization (Desi) Mass Spectrometric Imaging Of Spatially Regulated In Vivo Metabolic Rates, Charlotte Reininger Lewis

Theses and Dissertations

Desorption electrospray ionization (DESI) is an ambient ionization technique used for mass spectrometric imaging of biological samples. When coupled with isotopic ratio measurements of deuterium-labeled tissues, DESI provides a means of measuring metabolic rates on a spatially resolved basis. In vivo metabolic rates are desired to better understand diseases such as Alzheimer's, Parkinson's, Huntington's, and various forms of cancer that negatively impact metabolic rates within different organs of the human body. Although DESI has been used to image lipids and metabolites of a variety of tissues and other imaging techniques, such as NIMS, have been used to study kinetic turnover …

This survey study gathered data from teachers of many different languages, including ASL, all at the secondary level in the state of Utah. The study attempts to describe how secondary FL teachers view the role of culture in language teaching. It also details which models, means, or methods teachers use to communicate culture to their students, as well as the amount of culture included in their lesson planning, instruction, and assessment. Factors that contribute to more culture inclusion in the …

Machine Learning In Surface Ocean Co2 Mapping, Jive Zeng, Nobuko Saigusa, Tsuneo Matsunaga, Tomoko Shirai

International Congress on Environmental Modelling and Software

Carbon dioxide (CO2) is a major greenhouse gas affecting long term global climate change. According to the Global Carbon Budget 2013 (Quéré et al., 2014, Earth Syst. Sci. Data, 6, 235–263), total global carbon emissions increased from 3.9 GtC/yr in 1959 to 10.7 GtC/yr in 2012, of which approximately 43% remained in the atmosphere, 30% went to terrestrial sinks, and 27% to the oceans. A method to estimate the oceanic sink is by calculating the air-sea CO2 exchange rate of CO2. While obtaining accurate distributions of the surface ocean CO2 (SOC) is critical to minimize uncertainty for this method, it …

From Climate Change Awareness To Energy Efficient Behaviour, Leila Niamir, Tatiana Filatova

International Congress on Environmental Modelling and Software

Understanding and predicting how climate will change, and whether and how a transition to low-carbon economies will develop over the next century is of vital importance. Nowadays there is high competition between countries to achieve a low-carbon economy. They are examining different ways e.g. different energy efficient technologies and low-carbon energy sources, however they believe that human choices and behavioural change has a crucial impact, which is many times discussed in the literature as well. In this paper, we aim to discuss challenges related to modelling behavioural changes on the demand side and show effect of the demand side activation …

An Integrated Interdisciplinary Modelling System Of Climate Change Impacts On Agriculture In Support Of Adaptation Planning: Mosaicc, Hideki Kanamaru, Mauro Evangelisti

International Congress on Environmental Modelling and Software

Food and Agriculture Organization of the United Nations developed a server-based integrated system of tools and models called MOSAICC to evaluate climate change impacts on the agriculture sectors (crops, water resources, forests, and economy). MOSAICC is designed to respond to the needs of developing countries which may benefit from institutional and individual capacity development in producing relevant information for national climate change adaptation planning. This innovative system design facilitates a participatory environment where researchers with different installations on the user's computer and makes maintenance and update of the system on the centralized server simple. MOSAICC is based on open-source technology …
