Experimental Planting Of Native Shrubs On Santa Cruz Island From Small Nursery Stock, Matthew L. James, David M. Hubbard, Coleen Cory

Monographs of the Western North American Naturalist

The natural vegetation of Santa Cruz Island was severely disturbed by nonnative herbivores for well over a century. As the livestock and feral ungulates (primarily sheep, cattle, and pigs) were removed from the island over the last 30 years, many of the native plant communities began to recover naturally. Recovery has been extremely slow in other areas, especially where nonnative annual grasses and fennel (Foeniculum vulgare) dominate several hundred hectares that were under intense agricultural use (pastures and farmed lands). We experimentally tested the feasibility of speeding up the recovery process in a postagricultural area of the island’s …

Space Use And Home-Range Size Of Barn Owls On Santa Barbara Island, Sarah K. Thomsen, Caitlin E. Kroeger, Peter H. Bloom, A. Laurie Harvey

Monographs of the Western North American Naturalist

Spatial overlap between predators and prey is often a key component of predator-prey interactions. Barn Owls (Tyto alba) are important predators of some species of conservation concern on the Channel Islands in southern California; therefore, understanding patterns of owl space use on these islands could provide insights on variations in predation risk that may be useful for conservation efforts of Barn Owl prey. In this study, our objectives were to investigate home-range size and space use by individual owls on Santa Barbara Island, which at 2.6 km² is the smallest island within the Channel Islands National Park. …

The Implications Of Increased Body Size In The Song Sparrows Of The California Islands, Raymond M. Danner, Russell Greenberg, T. Scott Sillett

Monographs of the Western North American Naturalist

We investigated morphological divergence between mainland and California Island populations of the Song Sparrow (Melospiza melodia). Body size in small terrestrial vertebrates has been hypothesized to be larger in island forms than in their mainland relatives. Previously, we established that although bill size in island populations was similar to that in mainland populations with similar climate, bill-size dimorphism averaged much greater on the islands. In this paper, we compare various measures of structural body size and body mass between the California Islands and the mainland. We found that average body mass is over 10% higher in island Song …

Status Of The Santa Catalina Island Fox Thirteen Years After Its Decline, Julie L. King, Calvin L. Duncan, David K. Garcelon

Monographs of the Western North American Naturalist

Santa Catalina Island was home to an estimated 1342 adult island foxes (Urocyon littoralis catalinae) in 1990. Nine years later, fox sightings declined and reports of dead or dying foxes increased. An island-wide trapping effort was initiated after a fox carcass tested positive for Canine distemper virus (CDV). In 1999, only 10 foxes were captured east of the Two Harbors isthmus during 1046 trap-nights. A multifaceted conservation plan was implemented in 2000 to conserve the Santa Catalina population of island fox. Initial recovery actions took place from 2000 to 2005 and resulted in the translocation of 22 juvenile …

On The Origins Of The Insect Fauna Of California's Channel Islands: A Comparative Phylogeographic Study Of Island Beetles, Michael S. Caterino, Stylianos Chatzimanolis, Maxi Polihronakis Richmond

Monographs of the Western North American Naturalist

California’s 8 Channel Islands host a large diversity of insects, the vast majority of which are shared with mainland southern California. The existence of a small number of recognized endemic species, however, suggest that, for some lineages, the islands are isolated enough to have permitted significant differentiation. Here we investigate the phylogeographic relationships of 4 beetle species (Thinopinus pictus, Hadrotes crassus, Hypocaccus lucidulus, and Nyctoporis carinata): all occurring on the mainland and on multiple (up to 6) Channel Islands. Sequences of the cytochrome oxidase I mitochondrial gene (and, for one species, an intron in the …

Changes In Vegetation And Biological Soil Crust Communities On Sand Dunes Stabilizing After A Century Of Grazing On San Miguel Island, Channel Islands National Park, California, Kristine L. Zellman

Monographs of the Western North American Naturalist

San Miguel Island is the westernmost of the California Channel Islands and one of the windiest areas on the west coast of North America. The majority of the island is covered by coastal sand dunes, which were stripped of vegetation and subsequently mobilized due to droughts and sheep ranching during the late 19th century and early 20^th century. Since the removal of grazing animals, vegetation and biological soil crusts have once again stabilized many of the island’s dunes. In this study, historical aerial photographs and field surveys were used to develop a chronosequence of the pattern of change in …

Strategies For Biosecurity On A Nearshore Island In California, Christina L. Boser, Coleen Cory, Kathryn R. Faulkner, John M. Randall, John J. Knapp, Scott A. Morrison

Monographs of the Western North American Naturalist

Islands provide refuge for many rare and endemic species but are especially vulnerable to invasion by nonnative species. Invasive alien species are a major factor in the imperilment and extinction of island biota. Biosecurity protocols are designed to prevent or quickly detect the transport of harmful nonnative species, with the goal of eliminating the high economic cost of invasive species removal and the biological cost of damage caused by nonnative organisms. Effective biosecurity protocols require a balanced approach to on-island monitoring, off-island surveillance and prevention practices, rapid response, and educational outreach. Here we use the biosecurity program on Santa Cruz …

Restoration Of A Coastal Wetland At Prisoners Harbor, Santa Cruz Island, Channel Islands National Park, California, Paula J. Power, Joel Wagner, Mike Martin, Marie Denn

Monographs of the Western North American Naturalist

Prisoners Harbor of Santa Cruz Island, California, was historically the site of a 4.86-ha coastal wetland and riparian system—the largest on the California Channel Islands. The site was occupied by native people for 3000 years until the 1830s. During the late 1800s, ranchers filled about half of the wetland area to build livestock corrals and other facilities. They also rerouted the main stream channel, Cañada del Puerto, and built a stone wall and earthen berm along its west bank. This disconnected the stream from its floodplain and inadvertently caused erosion of a Native American archeological site. The National Park Service …

Evaluation Of New Telemetry Technologies For Research On Island Foxes, Brian Cypher, Elizabeth Drake, Jennifer Savage, Julie King, Katherine Ralls, Timothy Coonan, John Perrine, Calvin Duncan

Monographs of the Western North American Naturalist

New telemetry technologies have recently become available for research on island foxes (Urocyon littoralis). These include GPS units, which collect location data, and proximity logger units, which record contacts between individuals. We evaluated these technologies on island foxes through 4 field studies. GPS collars were deployed on foxes on Santa Catalina during 2007–2008 (n = 20) and 2010–2011 (n = 5) and on Santa Rosa during 2009–2010 (n = 14). The GPS units had multiple issues including malfunctioning drop-off mechanisms, failure of some units to yield data, low location acquisition rates, improper factory programming, high rates of premature …

Identifying Evolutionarily Significant Units And Prioritizing Populations For Management On Islands, Jeanne M. Robertson, Kathryn M. Langin, T. Scott Sillett, Scott A. Morrison, Cameron K. Ghalambor, W. Chris Funk

Monographs of the Western North American Naturalist

Islands host exceptionally high levels of endemism compared to mainland regions and are subject to disproportionately high rates of extinction and imperilment. Therefore, the protection and preservation of taxonomic units that are endemic to islands is a key component in mitigating the loss of global biodiversity. However, determining what is “endemic” on islands can be challenging. Conservation units are commonly delineated based on genetic divergence at neutral loci (e.g., genetic differentiation at microsatellite loci or reciprocal monophyly based on mitochondrial genes). Island populations of nonvolant species are expected to meet this criterion, regardless of adaptive differences, due to geographic isolation, …

Cyber Sovereignty: The Way Ahead, Eric Talbot Jensen

Faculty Scholarship

The last few years are full of reports of cyber incidents, some of which have caused significant damage. Each of these cyber events raise important questions about the role and responsibility of States with respect to cyber incidents. The answer to these questions revolves in large part around the international law doctrine of sovereignty. The extent to which nations exercise sovereignty over cyberspace and cyber infrastructure will provide key answers to how much control States must exercise and how much responsibility States must accept for harmful cyber activities when they fail to adequately do so. This article argues that States …

Future War And The War Powers Resolution, Eric Talbot Jensen

Faculty Scholarship

Since its passage in 1973 over the veto of then-President Nixon, the War Powers Resolution (WPR) has been laden with controversy. Labeled as everything from ineffective to unconstitutional, the WPR has generally failed in its design to require notification and consultation to Congress by the President. Despite numerous proposals to amend the WPR, it continues to languish in the twilight of Executive war powers, and its future is bleak. With emerging technologies such as drones, cyber tools, nanotechnology, and genomics, the ineffectiveness of the WPR will prove even more profound. The WPR’s reliance on “armed forces” and “hostilities” as triggers …

Texas Groundwater And Tragically Stable “Crossovers”, Zachary Bray

BYU Law Review

One recurring question in the academic literature on common-pool resources relates to the persistence of “tragic” commons regimes—systems that encourage, or at least tolerate, the inefficient, wasteful, hazardous, or unfair exploitation of a resource that is easily accessed for and diminished by individual use and consumption. Of course, not all commons are tragic: some common-pool resources invite individual access in efficient, fair, and durable ways. Yet many commonly held resources do lie under systems of governance that are not just tragic but persistently and stubbornly so. Often the tragic aspects of such commons regimes are well known; indeed, for some …

Isolated Wetland Commons And The Constitution, Blake Hudson, Mike Hardig

BYU Law Review

Isolated wetlands provide great ecological and economic value to the United States. While some states provide protection for isolated wetlands, a great many do not. These wetlands are also left outside the ambit of federal wetland regulatory protections under the Clean Water Act, with its murky jurisdictional reach. Notwithstanding jurisdictional questions under current federal statutes, the U.S. Supreme Court has gone so far as to call into question the constitutionality of federal isolated wetland regulation. This Article makes a normative argument that, in the absence of state or local programs providing holistic isolated wetland protection, federal action is needed. The …

Contactless Measurement Of Angular Velocity Using Circularly Polarized Antennas, Vit Sipal, Adam Narbudowicz, Max Ammann

Articles

An innovative method to measure the angular velocity using circularly polarized antennas is proposed. Due to the properties of circular polarization, the angular velocity is frequency modulated (FM) on a wireless carrier. This enables a low-cost precise continuous measurement of angular velocity using a standard FM demodulator. The hardware can be easily adapted for both high and low angular velocity values. The precise alignment angle between the antennas can be determined if the initial antenna orientation is known. The angular error is shown to be

What We Have Learned About Grassroots Philanthropy: Lessons From Mexico, Artemisa Castro Félix, A. Scott Dupree

The Foundation Review

Mexico is going through a transition from traditions of authoritarian, top-down social and political management that have tended to marginalize the efforts of community groups in addressing social and environmental challenges.

While there are many important questions about strengthening civil society organizations in general, grassroots groups in particular are challenged by the weak enabling environment for social action.

Despite this, the Action in Solidarity Fund has found that it is very possible for philanthropists to reach small grassroots groups with the support they need and to begin to strengthen the social fabric for communities to act on their own behalf. …

Drugs, Depression, And Dating Violence: Partnering With Schools To Collect And Use Data On Adolescent Risky Behaviors, Rebecca H. Donham, Shari Kessel Schneider

The Foundation Review

In 2005, the MetroWest Health Foundation launched a 10-year initiative to conduct the federal Centers for Disease Control and Prevention’s Youth Risk Behavior Survey biennially with every high school and middle school student in the foundation’s 25-town region. The survey asks students about substance use, violence, sexual behaviors, mental health, and nutrition.

In the first year of the initiative, about two-thirds of public high schools and half of the middle schools in the region participated. By 2012, every public high school and middle school participated. Encompassing some 40,000 students, the survey is considered to be one of largest, if not …

Maximizing Return: An Evaluation Of The Walton Family Foundation’S Approach To Investing In New Charter Schools, Matthew Carr, Marc Holley

The Foundation Review

The Walton Family Foundation’s social-impact goals include reform of the American K-12 education system by increasing the number of highquality schools available to low-income students. One of the foundation’s signature strategies toward this end is to support charter schools.

This article presents the findings of a study that suggests the foundation’s investment approaches to charter school startups have been successful in supporting the creation of high-quality seats for low-income students. Specifically, the foundation has invested in charter schools where test-score performance has shown greater improvements than at local district schools and charter schools that have not received foundation funding.

These …

Peeking Behind The Curtain: The Operations And Funding Priorities Of Rural Private Foundations, Dorothy Norris-Tirrell, Brandi Blessett, Claire Connolly Knox

The Foundation Review

This article examines the operations and funding priorities of rural private foundations in Florida, using data from the U.S. Census, the Urban Institute’s National Center for Charitable Statistics, and interviews with foundation leaders.

The study found that grantmaking by rural foundations is split between out-of-state and in-state giving, determined by the intent of a benefactor or the personal choices of a foundation founder and/ or family.

This finding presents opportunities for nonprofit organizations and community groups in rural counties to communicate community needs in order to retain a larger amount of foundation dollars in the foundation’s home state and county.
