The Ecological Implications Of Visitor Transportation In Parks And Protected Areas: Examples From Research In Us National Parks, Christopher Monz, Ashley D'Antonio, Steve Lawson, Jesse Barber, Peter Newman

Christopher Monz

The demand for recreation and nature-based tourism experiences in parks and protected areas continues to grow in many locations worldwide and in response, many parks are employing transit services designed to improve visitor access. Transit services (e.g., public bus service) are a component of the overall park transportation system and are very desirable in park settings as they yield many advantages over personal auto access including reduced congestion in parking areas, reduced carbon footprint, and an enhanced visitor experience. However, a growing body of research also suggests that the delivery of visitors via transit to destinations within a park or …


Contrasting Effects Of Different Mammalian Herbivores On Sagebrush Plant Communities, Kari E. Veblen Jan 2015

Contrasting Effects Of Different Mammalian Herbivores On Sagebrush Plant Communities, Kari E. Veblen

Kari E. Veblen

Herbivory by both grazing and browsing ungulates shapes the structure and functioning of terrestrial ecosystems worldwide, and both types of herbivory have been implicated in major ecosystem state changes. Despite the ecological consequences of differences in diets and feeding habits among herbivores, studies that experimentally distinguish effects of grazing from spatially co-occurring, but temporally segregated browsing are extremely rare. Here we use a set of long-term exclosures in northern Utah, USA, to determine how domestic grazers vs. wild ungulate herbivores (including browsers and mixed feeders) affect sagebrush-dominated plant communities that historically covered ~62 million ha in North America. We sampled …


Native And Domestic Browsers And Grazers Reduce Fuels, Fire Temperatures, And Acacia-Ant Mortality In An African Savanna, Kari E. Veblen Jan 2014

Native And Domestic Browsers And Grazers Reduce Fuels, Fire Temperatures, And Acacia-Ant Mortality In An African Savanna, Kari E. Veblen

Kari E. Veblen

Despite the importance of fire and herbivory in structuring savanna systems, few replicated experiments have examined the interactive effects of herbivory and fire on plant dynamics. In addition, the effects of fire on associated ant-tree mutualisms have been largely unexplored. We carried out small controlled burns in each of 18 herbivore treatment plots of the Kenya Long-term Exclosure Experiment (KLEE), where experimentally excluding elephants has resulted in 42% greater tree densities. The KLEE design includes six different herbivore treatments that allowed us to examine how different combinations of megaherbivore wildlife, mesoherbivore wildlife, and cattle affect fire temperatures and subsequent loss …


Monitoring Of Livestock Grazing Effects On Bureau Of Land Management Land, Kari E. Veblen Jan 2014

Monitoring Of Livestock Grazing Effects On Bureau Of Land Management Land, Kari E. Veblen

Kari E. Veblen

Public land management agencies, such as the Bureau of Land Management (BLM), are charged with managing rangelands throughout the Western United States for multiple uses such as livestock grazing and conservation of sensitive species and their habitats. Monitoring of condition and trends of these rangelands, particularly with respect to effects of livestock grazing, provide critical information for effective management of these multi-use landscapes. We therefore investigated the availability of livestock grazing-related quantitative monitoring data and qualitative region-specific Land Health Standards (LHS) data across BLM grazing allotments in the Western United States. We then queried university and federal rangeland science experts …

Megaherbivores And Cattle Alter Edge Effects Around Ecosystem Hotspots In An African Savanna, Kari E. Veblen Jan 2013

Megaherbivores And Cattle Alter Edge Effects Around Ecosystem Hotspots In An African Savanna, Kari E. Veblen

Kari E. Veblen

Wild mammalian herbivores and cattle are fundamental drivers of African savanna ecosystems and have strong impacts on woody vegetation. However, few experimental studies have investigated the separate and combined influences of different large herbivores on spatial vegetation patterning. In East Africa, temporary cattle corrals (bomas) develop after abandonment into productive, treeless ‘glades’ that attract both domestic and wild herbivores. Edges of glades exhibit unusually high densities of large trees. We used a long-term, broad-scale manipulative experiment to test whether megaherbivores (elephants and giraffes), wild meso-herbivores (15–1000 kg), or cattle caused shifts in woody plant abundances in glade edges. We also …

Pathways For Positive Cattle-Wildlife Interactions In Semi-Arid Rangelands, Kari E. Veblen Jan 2011

Pathways For Positive Cattle-Wildlife Interactions In Semi-Arid Rangelands, Kari E. Veblen

Kari E. Veblen

Livestock-wildlife interactions in rangelands are often viewed in terms of competition, but livestock and native ungulates can also benefit each other through long- term modifications of rangeland habitats. Here we synthesize research on rangelands in central Laikipia focusing on two types of cattle-wildlife interactions that have implications for their long-term coexistence. The first interaction occurs via redistribution of soil nutrients within the ecosystem, which is a consequence of the use of bomas (temporary corrals) to manage livestock. Our studies on two different soil types show that rotational boma management creates hectare-scale patches in the landscape that are enriched in soil …


An Entrepreneurial Approach To Librarianship, Flora G. Shrode, Jennifer R. Duncan, Wendy Holliday Apr 2010

An Entrepreneurial Approach To Librarianship, Flora G. Shrode, Jennifer R. Duncan, Wendy Holliday

Flora Shrode

Librarians from Utah State University explain recent efforts to encourage subject librarians to take a more holistic view of their roles. We are shifting from a traditional emphasis primarily on collection development and refocusing on natural connections between collections, instruction, liaison, and reference service. The poster provides background about Utah State University’s situation and explains our approach to analyzing local needs and culture to inform development of a new organizational structure. We describe our vision of subject librarianship, the process by which we assessed librarians’ ideas and goals for performing as subject librarians, and the actions we are taking to …

Contrasting Effects Of Cattle And Wildlife On The Vegetation Development Of A Savanna Landscape Mosaic, Kari E. Veblen Jan 2010

Contrasting Effects Of Cattle And Wildlife On The Vegetation Development Of A Savanna Landscape Mosaic, Kari E. Veblen

Kari E. Veblen

Through their effects on plant communities, herbivores can exert strong direct and indirect effects on savanna ecosystems and have the potential to create and maintain savanna landscape heterogeneity. Throughout much of sub‐Saharan Africa, periodic creation and abandonment of livestock corrals leads to landscape mosaics of long‐term ecosystem hotspots that attract both cattle and large ungulate wildlife. The development and maintenance of vegetation in these types of hotspots may be controlled in part by herbivory. Cattle and wildlife may have different, potentially contrasting effects on plant succession and plant–plant interactions. We ask how cattle and wild herbivores affect the maintenance and …

California Grasslands Alkali Specialist, Hemizonia Pungenspungens, Prefers Non-Alkali Soil, Kari E. Veblen

Kari E. Veblen

Edaphically severe habitats commonly support edaphic endemics, specialized plant species that do not occur elsewhere. The endemism of native plant species in edaphically specialized habitats suggests either (a) that these native endemic species are uniquely specialized to survive and grow better under the conditions prevalent in these harsh areas, or (b) that these areas represent refuges from competition with other (often exotic) species.


Tackling Aquatic Invasions: Risks And Opportunities For The Aquarium Fish Industry, Kari E. Veblen Jan 2009

Tackling Aquatic Invasions: Risks And Opportunities For The Aquarium Fish Industry, Kari E. Veblen

Kari E. Veblen

The aquarium trade is an important and rapidly growing vector for introduced species in the United States. We examined this vector by surveying pet stores in the San Francisco Bay–Delta region to compile a list of aquarium fish species commonly stocked. We identified which of these species might be able to survive in the Bay–Delta, and investigated store representatives’ knowledge and attitudes about biological invasions. A restrictive analysis using conservative estimates of fish temperature tolerances and environmental conditions found that the local aquarium trade includes 5 fish species that can survive in a temperate system such as the Bay–Delta. Under …

Preventing Horticultural Introductions Of Invasive Plants: Potential Efficacy Of Voluntary Initiatives, Kari E. Veblen Jan 2007

Preventing Horticultural Introductions Of Invasive Plants: Potential Efficacy Of Voluntary Initiatives, Kari E. Veblen

Kari E. Veblen

Although prevention is the most cost-effective way to avoid the enormous expenses associated with plant invasions, invasive plants continue to be imported as trade commodities for horticultural use. With very little government regulation of horticultural imports of invasive plants, efforts have turned toward fostering voluntary initiatives to encourage self-regulation by the horticulture trade. Our study takes the first step toward evaluating the potential success of these voluntary initiatives. We conducted a survey of nursery professionals to gauge their perceptions of invasive species, the role of the horticulture trade in invasive plant introductions, and their participation—potential and actual—in preventive measures outlined …
