Coast Redwood Fire History And Land Use In The Santa Cruz Mountains, California, Gregory Jones

Master's Theses

Physical evidence of past fires, left in the form of cambial scars, suggests that low and moderate intensity fires have burned periodically for centuries in the coast redwood (Sequoia sempervirens) forest in California's central coast bioregion. These fires may have played an important role in shaping stand age structure and composition. Nonetheless, the ecological role of fire in shaping successional processes in the redwood ecosystem is not well understood. The extent to which both aboriginal and more recent burning practices have affected the central coast landscape is also uncertain. Standard dendrochronology techniques were used to reconstruct and analyze …

Environmental Education As A Catalyst For Changing Students' Environmental Attitudes: A Survey Of Ten Universities In The Tokyo Bay And San Francisco Bay Areas, Minako Nishiyama

Master's Theses

Environmental education has been internationally recognized as a key tool to counter increasing threats to the environment. Previous studies have found that environmental values and beliefs are the fundamental factors that shape various pro-environmental behaviors. This study aimed to increase our understanding of how environmental education during childhood and university periods influence students' sense of connectedness to nature and ecological worldview. Two measures, the Connectedness to Nature Scale (CNS) and the New Ecological Paradigm (NEP) scale, were used for this purpose. A total of 1,266 students in 10 universities in the San Francisco Bay Area and Tokyo Bay Area participated …

Survival And Recovery Following Wildfire In The Southern Range Of The Coast Redwood Forest, Rachel Lazzeri-Aerts, Will Russell

Faculty Publications, Environmental Studies

Fire plays a central role in determining structure, composition, and recruitment in many forest types. In coast redwood forests, the role of fire is not well understood and scant literature exists on post-fire response, particularly in the southern part of the range. In order to better understand patterns of survival and recruitment following fire for coast redwood (Sequoia sempervirens [lamb. ex D. Don] Endl.) and associated tree species, three sites in the Santa Cruz Mountains, California, USA, were sampled following wildfire. Randomly selected 10 m diameter plots were used to collect data on survivorship and post fire regeneration in order …

An Analysis Of An Andean Cosmovisión: Nature, Culture, Ecology, And Cosmos, Christian Ardeleanu

Master's Theses

Modern life may offer certain benefits for humanity, but it can also create a barrier between humans and the natural world. In contrast, the millenarian Aymara culture of the Bolivian Andes exhibits a harmonic interrelation with nature, ecology, and the cosmos, and it also represents a living system of indigenous knowledge and knowledge production/transformation. The Aymara system of knowing and knowledge production, like other indigenous systems, should not be mistaken for antiquated elements of culture and folklore but should be seen as a distinct and dynamic epistemology. The Aymara cosmovisión is similar to the philosophy of ecology, sharing some general …

Characterization And Development Of An Extended Cavity Tunable Laser Diode, Fnu Traptilisa

Master's Theses

A laser diode emits a narrow range of frequencies. However, drifts in

frequency occur over time due to many factors like changes in laser temperature, current, mechanical vibrations in the apparatus, etc. These frequency drifts make the laser unsuitable for experiments that require high frequency stability. We have used an atomic transition in rubidium as a frequency reference and used Doppler

free saturated spectroscopy to observe the reference peak.

We have designed an electronic locking circuit that operates the diode laser at a specific frequency. It keeps the laser at that frequency for a long period of time with very …

Ecotourism As A Tool For Conservation Of Coast Redwoods In Santa Cruz County, California, Chandana Rao

Master's Theses

According to the World Tourism Organization, ecotourism is the fastest growing segment of the tourism industry, generating $300 billion in annual revenue. Ecotourism aims to control the damaging effects of conventional mass tourism and tries to overcome tourism's environmental and socio-cultural challenges. In an ideal situation, ecotourism can help conserve fragile biodiversity, build ties between parks and communities, and increase awareness of environmental issues; it also includes a profit impetus for businesses.

This research was conducted to evaluate the potential for developing ecotourism as a conservation tool in the four redwoods state parks of Santa Cruz County. The study assessed …

Natural Recovery Of Second-Growth Coast Redwood Stands In The Santa Cruz Mountains, Jeffrey M. Sinclair

Master's Theses

The natural recovery of coast redwood forests following a logging event is not fully understood. Recent studies, in the redwood central range, have found that un-restored and unmanaged second-growth forest stands can begin to recover and exhibit characteristics of old-growth stands within 100 years or less. The goal of this study was to determine if redwood stands in their southern range are recovering naturally. A total of 160 sample plots were selected randomly within old-growth and second-growth study sites. The data collected included stand density, tree size structure, canopy cover, species diversity, and species composition. Special habitat features were analyzed …

Amphibian Mortality On Roads: A Case Study In Santa Cruz Long-Toed Salamander Habitat, Michael Thomas Hobbs

Master's Theses

Amphibian populations have been declining at higher rates than bird and mammal populations. Agriculture, urbanization, including roads, and resource extraction continue to put pressure on all species. Roads in particular, are major sources of mortality. The Santa Cruz long-toed salamander (Ambystoma macrodactylum croceum), one of the most critically endangered species in the US, is one amphibian that is declining as a result of anthropogenic impacts, especially habitat loss and fragmentation due to urban development. Migration across roads puts these salamanders at risk from road-related death. This thesis quantified the rate of road mortality to these salamanders and other common amphibians …

Benthic Invertebrate Response To Habitat Complexity In South Bay Salt Ponds, Jessica Louise Murphey

Master's Theses

Wetlands are unique ecosystems that support specific flora, fauna, hydrology, and geology. These ecosystems increase groundwater availability, improve water quality, decrease flood water impacts, and help decrease shoreline erosion. In the south San Francisco Bay, the South Bay Salt Pond Restoration Project is restoring over 6,000 hectares of former salt ponds to tidal marshes and managed pond habitats. These habitats will support endangered species as well as migratory birds, diving ducks, invertebrates, and algal species. Benthic invertebrates are a vital piece of the South Bay food web as they provide the sustenance for other invertebrates, fish, shorebirds, and waterfowl. Improving …

Basking Western Pond Turtle Response To Trail Use In Mountain View, California, Paul Eric Nyhof

Master's Theses

The western pond turtle (Emys marmorata) is the only native freshwater turtle in California, and it is listed as a California Species of Special Concern. One population near Moffett Naval Air Station in Northern California uses a highly altered water channel along a recently opened section of the Bay Trail, exposing western pond turtles (WPT) to high rates of human activity through recreational trail use. This research assessed whether human recreational trail use had a measurable effect on WPT basking behavior. WPTs were also trapped and marked to collect data on the structure and stability of the current population.

The Sjsu Ecological Footprint Challenge And Its Impacts On Pro-Environmental Behavior, Matthew Eugene Lambert

Master's Theses

Estimates suggest that humanity requires one-and-a-half Earths to sustainably provide the resources demanded. Observed consequences of this are rising atmospheric carbon, loss of arable land, fishery collapse, drinking water scarcity, and irreparable degradation to the Earth's ecosystems. The ecological footprint is a tool that calculates the amount of land needed to support a population or an individual's level of resource use. The action of calculating an individual's footprint has been shown to improve knowledge about environmental issues, change attitudes about natural resources, and increase understanding about the connection between one's actions and the environment.

This research examined the impacts of …

The Effectiveness Of Experiential Environmental Education: O'Neill Sea Odyssey Program Case Study, Lauren Elizabeth Hanneman

Master's Theses

Environmental education programs aim to develop participant awareness, sensitivity, and understanding of their affective relationship to the natural environment through conceptual knowledge and personal experiences. Previous findings have suggested that participation in environmental education programs leads to short-term positive increases in environmental knowledge, pro-environmental attitudes, and intentions to act in environmentally responsible behaviors; however, few studies have included long-term, follow-up assessment. This research provided an analysis of the effectiveness of the O'Neill Sea Odyssey (OSO) education program in fostering a long-term awareness of personal responsibility about ocean pollution among student participants.

A survey administered to 261 students from the greater …

The Genetic Diversity And Population Structure Of The Dugongs (Dugong Dugon) Of Thailand, Jessie Barr Bushell

Master's Theses

The dugong (Dugong dugon) is indigenous to the coastal waters of the Indo–Pacific Ocean and is vulnerable to extinction throughout its range due primarily to anthropogenic effects. In Thailand the population of dugongs is approximately 250 animals and is found in fragmented habitats along the Thai coast. Genetic studies were implemented in this study to assess regional genetic composition and determine if there is variation in the D–loop sequences or microsatellites consistent with philopatry to regions, by males or females, or indicating dispersal. Utilizing D–loop sequences, 27 haplotypes were found that grouped into three haplogroups that were not …

Response Of Waterbirds To Salt Pond Enhancements And Island Creation In The San Francisco Bay, Stacy M. Moskal

Master's Theses

Historically, San Francisco Bay supported the largest salt pond complex on the Pacific coast of North America, and these areas have been used by large numbers of migrating and wintering waterbirds for more than a century. In 2003, salt ponds in the South San Francisco Bay were purchased with a goal of restoring 50-90% of the 6100 ha of former salt ponds to replace lost tidal marsh habitats. However, a major challenge for the restoration project has been maintaining the abundance of non-breeding waterbirds in a smaller footprint of managed ponds. Thus, in 2009-2010, Pond SF2 was enhanced with 30 …

Restoring Native Plants Following Invasive Malephora Crocea (Coppery Iceplant, Aizoaceae) Eradication On Anacapa Island, Nathan William Hale

Master's Theses

To avoid unintended complications of invasive species eradication, it is important to understand the potential implications of the techniques used in species eradication efforts. This study aimed to compare how different methods of removing Malephora crocea affect the survivorship of planted seedlings of native perennial plants on Anacapa Island. Employing a randomized complete block design in an M. crocea stand, three removal treatments were tested: 1) hand-pull; 2) spray with herbicide and leave skeletons; and 3) spray and then remove skeletons after 2.5 months. In each treatment, seedlings of three species (Leptosyne gigantea, Frankenia salina, and Grindelia …

An Ecological Assessment Of Insect Diversity At Organic Central Coast Vegetable Farms On Two Spatial Scales, Emily Musgrave

Master's Theses

Modern industrial agriculture is the principal cause of anthropogenic land use changes for terrestrial ecosystems. Approximately 40% of the planet's land surface, or half of the habitable area, is now composed of agricultural landscapes. The simplification and industrialization of agriculture are the biggest drivers of global biodiversity loss, especially on Californian's Central Coast. Diversified organic agriculture, however, may offer some refuge for non-crop species. In this study we analyzed insect and plant biodiversity on and adjacent to organic vegetable farms on the Central Coast of California at two spatial scales, the landscape-scale and a smaller within-farm scale. At the landscape-scale, …

Farms On Campus: Strong Stakeholder Support For An Educational Garden At A Non-Land-Grant University, Gina M. Bacigalupi

Master's Theses

University farms and gardens are increasingly seen as effective tools for learning a variety of academic subjects and as resources that allow users to connect experientially to nature. Most existing university farms, however, are found at resource-rich land-grant universities. This research evaluated stakeholder interest and willingness-to-pay in money, time, and labor for a proposed educational farm at a public, urban, non-land-grant university through an online survey of over 400 members of the California State University East Bay, Concord Campus community. Overall, support for an educational farm at this site was high amongst all stakeholder groups. Students and stakeholders who hold …

Western Burrowing Owl Predation In An Urban Setting In California: Do California Ground Squirrel Calls Reduce Risk?, Lisa Anne Henderson

Master's Theses

Western burrowing owls are found in ground squirrel burrows throughout the urbanized landscape of the South San Francisco bay area, where they are threatened by habitat loss and degradation, prey limitation and predation. Previous research has characterized effects of habitat loss and prey-base limitations on owls, but the interplay between ground squirrels, owls and their predators has not yet been studied. The objective of this study was to assess the rate and types of predation interactions faced by Western burrowing owls and the extent to which California ground squirrels help burrowing owls reduce risk through alarm calling at Moffett Federal …
