California has been traditionally a Republican state, yet the Republicans have been unable to regain their traditional dominance since their defeat in 1958. The 1958 election represented a fundamental shift in the nature of California politics. More than that, the defeat of the Republicans pointed up a fundamental weakness in the Republican party.

My research has focused on the identification, assemblage dynamics, and horizontal distribution patterns of larval fishes around rocky reefs in the Gulf of California, Mexico. In Chapter One, I analyze a series of light-trap collections taken over 35 nights at San Carlos, Sonora. Nearly 14,000 larvae from 19 families were collected. The five most abundant families contributed 90% of the larvae and the top ten families contributed 99%. Larvae of non-pelagic spawners (gobiids, labrisomids, tripterygiids, chaenopsids, pomacentrids, and bythitids) dominated the collections. Larval catches ranged from 7.5 to 2330.3 larvae/45 min, but changes in catch rate were not related to changes in ambient moonlight. In contrast, the volume of zooplankton collected was correlated with moonlight intensity. Dynamics of the ten dominant fish families were highly variable, but in most cases a large proportion of the larvae were caught on just a few nights. Taxonomic and size selectivities were apparently less severe in my study than in previous Australian studies, and the use of light-traps should be explored further. In Chapter Two, I outline the prediction that larvae of small, non-pelagic spawning fishes should more frequently be retained over reefs during development than fishes with other combinations of body size and egg type, and I describe my research testing this prediction. I made about 160 collections of fish larvae with a light-trap and plankton net at 1, 20, and 100 m from rocky shorelines. These collections yielded 27,265 larvae from about 50 families. Based on larval size frequencies, near-reef concentration gradients, and abundances offshore, I identified four families that can complete development over the reef but also have larvae dispersed offshore (Clupeidae, Engraulididae, Gerreidae, and Haemulidae). In addition, I identified seven families that primarily develop over reefs and have few or no larvae dispersed offshore (Tripterygiidae, Chaenopsidae, some Labrisomidae, Dactyloscopidae, some Gobiidae, Gobiesocidae, and Bythitidae). Adults of these seven families are mostly small, non-pelagic spawners. Larvae from four taxa of larger non-pelagic spawners (Ophioblennius, Labrisomus, Balistes, and Pomacentridae) did not appear to develop over reefs. These findings are in accord with the prediction I made. Chapter Three is a preliminary guide to identification of Gulf of California blennioid larvae. Although blennioid larvae are poorly known and few species have been described, they are well represented (ca. 20,000 larvae from five families) in my collections taken near reefs in the Gulf. Illustrations of 20 species, and brief descriptions of key characters for these and several additional species, are provided. More detailed taxonomic studies on Gulf blenniid, dactyloscopid, tripterygiid, labrisomid, and chaenopsid larvae are in progress.

Understanding how institutions affect or shape fisheries performance is an important part of providing practical insights for the development of management strategies that promote sustainable fishing. In the Gulf of California there is widespread evidence of declines in fish stocks upon which small-scale fisheries depend and these declines are largely attributed to policy failures. Using methods commonly used in social sciences, I investigated the formal and informal rules regulating resource use by smallscale fishers from two fishing communities in the Northern Gulf of California (NGC), Bahía de Kino and Bahía de los Ángeles, Mexico, and their effects on fisheries sustainability. Some of the main results are summarized below: a) The percentage of fishers holding fishing rights and actually using them to report and commercialize catch was quite small in both communities (fishing rights are usually in the hands of absentee operators). b) Current policies and policy changes do not reach the fishers in a direct and formalized way in any of these communities, and these policies are shaped with no participation of local fishers. c) Current policy tools show poor performance in practice and have been ineffective (at the moment) in promoting sustainable fishing practices by fishery stakeholders. Neither community has been able to manage their resources sustainably. Results also suggest some potentials that could lead to more sustainable fishing practices in both communities: d) The presence of informal rights (fishers' sense of ownership) over the fishing grounds in the surroundings of their home communities. Generally, local fishers do not conform to or enforce the individual boundaries of the fishing rights they hold (or work under), but they do care about and defend an area that they perceive as belonging to their community as a whole, particularly when there are "outsiders" coming in. e) The presence of strong support from the fishers for implementing improved regulatory measures for local fisheries. Specific recommendations for each case study are provided with the aim of enhancing rules legitimacy and improving management outcomes.

There is vigorous debate regarding possible changes in the spatial and temporal attributes of chaparral fire regimes within southern California. We employed a novel approach to reconstruct a multi-century record chaparral fire history and to evaluate the effects of climate on these fire regimes across three southern California National Forests. The research in this dissertation is presented as three related studies. The first focused on using fire scars and tree rings from isolated stands of bigcone Douglas-fir (Pseudotsuga macrocarpa), which we demonstrate as reflective of the temporal and spatial patterns of fire in the surrounding chaparral. We found many extensive fires were apparent in both the pre-and post-twentieth century period indicating that such events were a natural component of the system. The second study applied the same approach but the spatial extent of the project was expanded to examine fire histories at a regional scale. Our results confirm that widespread fire events have, for centuries, likely played a critical role in shaping the fire regime of southern California chaparral landscapes. We found that such events occurred on a multi-decadal interval and that interval lengths have nearly doubled since the turn of the century. The third study examined the relationship between antecedent climate and wildfires in chaparral landscapes across southern California. We found that acute drought, driven by antecedent cool season precipitation in the previous winter and spring, was a reliable indicator of increased wildfire activity in the past; however, we now find a contemporary system influenced by antecedent climate in the two years prior to the fire event and no immediate connections to climatic drivers is apparent in the year of the event. The broader results from these three studies indicate that some changes in fire return intervals have occurred in the modern era but widespread fires have been and remain an integral part of chaparral fire regimes. We hypothesis that land use in the 20th century has altered vegetation structure and composition so much so that chaparral fire regimes now respond differently to climatic cues than they had for the past 200-300 years.

Water management in California is an extremely complex issue that requires collaboration from all levels of government. As the water supply shrinks and demand pressures increase over the next century, water management will become increasingly difficult. There is no single solution to the water issues facing California but there are many incremental steps than can be taken to secure an efficient, sustainable, and environmentally friendly economy. Water conservation programs appear to be the most cost effective means of reducing water demand. This requires a combination of incentives to reduce consumption, education about the true cost of water for California, and regulatory reform to promote efficient use and distribution of water. The state needs to make investments in education about water in California for conservation measures to be successfully adopted and implemented by the general populace. From a policy perspective, higher levels of government in the state need to establish statewide performance standards for groundwater withdrawals, point and non-point pollution, flood risk, and watershed integration for local governments to enforce. In order for these changes in water policy to be implemented, strong leadership is necessary.

The juvenile justice system was originally set up under the philosophy that juveniles are inherently different than adults and therefore should not be subject to same harsh punishment as adult criminals. Rehabilitative treatment methods became the center of the juvenile justice system in order to reduce recidivism rates and help reintegrate youths back into society as smoothly as possible. This philosophy changed early in the 21st century, and many states began treating youth offenders in ways similar to adult offenders, with a particular increase in direct files of juveniles to adult court. After about a decade of harsh punishment, the system once again reverted back to the rehabilitative model. California did so through several legislative reforms; however these reforms have not been as successful as they should have been, and the system is still in a state of disarray. California is currently balancing a failing state juvenile justice system while trying to simultaneously support realignment efforts to the county level. After evaluating the failures of Division of Juvenile Justice and the capacity of the counties, it is evident that counties are not only physically equipped to take on the increased responsibility but are much better suited to do so financially. To best uphold the original goals of the juvenile justice system and the rehabilitative model, California should move to close the Division of Juvenile Justice and completely realign all responsibility to the counties. Keeping juveniles close to their communities creates stronger ties, more continuity of treatment, and reduces the likelihood a youth will reoffend. By tailoring treatment to the individual on a local level, problems such as mental illness, substance abuse, and anger management, can be directly targeted and solved. Intervening at first arrest with effective treatment programs is crucial to decreasing the chance that a juvenile will become a career adult criminal. These juveniles are the future of society; focusing on the rehabilitation of these youths will not only increase community safety but will also produce healthy, productive citizens to contribute to the economy.

During 1963-78 the governments and the top universities of Chile and California undertook three programs of binational development assistance and cooperation. The programs built on a long historical relationship between the two regions, marked by their striking similarities in physical geography and natural resources, despite being 1,000s of miles apart on opposite sides of the Equator. The first program was for technical development assistance to Chile in the framework of the Alliance for Progress, and involved the three governments of Chile, California, and the United States. Water resources and river basin development planning were a primary emphasis, and led to building Chile's largest dual-purpose reservoir (Colbun). The second program was for graduate-level academic exchange and involved the two leading public university systems, the University of Chile and the University of California. This comprehensive program was funded for more than a decade by the Ford Foundation, with agriculture, natural sciences, and engineering the dominant fields. The third program was a separate effort to reform Chilean legal education, led by Stanford Law School and funded by the Ford Foundation. This Chile Law Program was a leading international example of the "law and development" movement in the 1960s, which overlapped closely with the early years of the "law and society" movement in the U.S. Both university and law school programs ended after the Chilean military coup in 1973. What were the impacts of these programs on water, law, and society in both Chile and California? What lessons can we learn today from those historical experiences? We answer these questions with an historical overview and synthesis of diverse documents and evidence. In focusing on water, law, and society, we aim to contribute to the interdisciplinary synthesis of different fields of development studies.

Approved for public release; distribution is unlimited / The coastal cliff top line recession has historically been used to calculate erosion along the Southern Monterey Bay. Digital photogrammetry is used in this work to produce Digital Terrain Models (DTM), representing the coastal cliff top line of 1984. This links the historical recession data sets with the LIDAR measurements of 1997 and 1998 and a 2003 cliff top line measured using Kinematic DGPS. Recession time series starting in the 1940's are produced for several locations. Least square linear fits of the recession data are computed for the periods 1940-84, 1940-98 and 1940-03. At Fort Ord and Sand City the resulting slopes show a persistent erosion trend of 1meter/year, unchanged in the last 19 years. The mean sea level (MSL) evolution is studied using historical San Francisco MSL data because of its high correlation with Monterey MSL. Higher MSL during El NinÌ o years, coincident with higher erosion rates show the correlation between erosion and MSL. In the long term, high-erosion El NinÌ o years combine with normal years averaging to a near constant erosion trend. For Phillips Petroleum and Beach Lab a significant decrease in the erosion rate is observed after sand mining stopped in Sand City. Digital Photogrammetry provides a high-quality representation of the shoreline topography, offering useful information to the warfighter in terms of detailed beach or landing zone characterizations. / Lieutenant Commander, Spanish Navy
