Biodiversity and Genetic Structure of Benthic Macroinvertebrates Along an Altitudinal Gradient: A Comparison of the Windhond and Róbalo River Communities on Navarino Island, Chile

Description: Altitudinal gradients in Sub-Antarctic freshwater systems present unique opportunities to study the effect of distinct environmental gradients on benthic macroinvertebrate community composition and dispersal. This study investigates patterns in biodiversity, dispersal and population genetic structure of benthic macroinvertebrate fauna across an altitudinal gradient between two watersheds on Navarino Island in southern Chile. Patterns in diversity, density, evenness and functional feeding grou… more

The Chilean Experience, 1970-1981

Description: The election of a coalition of socialists and communists in 1970 and three years later, the assumption of a military government have led to much controversy around the world. This study attempts to analyze the economic conditions prevailing in Chile from 1970 to 1981. It examines the gradual deterioration of the nation's economy under the Unidad Popular government and the recovery that has taken place with the Junta Militar de Gobierno. The implementation of a market system in 1973 has been eff… more

Life History Biology of the Desert Nesting Seagull Larus modestus

Description: Gray gulls Larus modestus are unique among birds of northern Chile as the only species nesting in the interior Atacama Desert, and the only seagull nesting far (30 - 100 km) from surface water. During breeding-nesting (August - February) gray gulls congregate on the coast of northern Chile where they feed and initiate courtship. As early as August, breeding pairs commute daily to the inner desert to establish nesting territories, round-trip distances of 60-200 Km. During incubation (30 days) an… more

Modeling State Repression in Argentina and Chile: A Time Series Analysis

Description: This study is an attempt to contribute to the emerging theoretical literature on state repression. A time-series model was developed to test the hypothesis that state violence in Argentina and Chile is largely a function of four internal political factors and their interactions: 1) the inertial influence of past restrictive policies on the formulation of current policies, 2) the annual incidence of political protest demonstrations, 3) the perceived effectiveness of repressive measures on unrest… more

Nesting Ecology and Reproductive Correlates in the Desert-nesting Gray Gull Larus Modestus

Description: General objectives of my study were to describe the reproductive ecology of gray gulls in the large Lealtad colony, with emphasis on demographic parameters and physiological adaptations of eggs and chicks, which would complete some original objectives established in the early 1980's by Guerra and Fitzpatrick. Specifically, my study focused on describing, then comparing with other desert and non-desert nesting larids, interactive effects of ambient physical conditions and nest-site predation on … more

Niche Expansion of an Invasive Predator (Neovison vison), Prey Response, and Facilitative Interactions with Other Invasive Mammals at the Southern End of the Americas: Conservation Challenges and Potential Solutions

Description: The Cape Horn Biosphere Reserve is located at the southern tip of South America. This large archipelago is considered one of the last pristine areas left on the world. Despite it being an unpopulated area with most of the native forest cover intact, it has not been exempt from biological invasions, one of the major drivers of biodiversity loss. Three species that naturally interact in their native range in North America – American beavers (Castor canadensis), muskrats (Ondatra zibethicus), and … more

Political Factors in the Creation and Implementation of the Andean Foreign Investment Code

Description: The purpose of this investigation is to examine the political factors which came into the creation and implementation of the Andean Foreign Investment Code. This study analyzes the political forces in the creation of the Code and examines the implementation of the Code in each of the Andean countries. This investigation concludes that although the Code has not been implemented uniformly in the Andean countries, it remains an important part of the Andean Common Market. In addition, the continual… more

Salvador Allende: the Rise and Fall of a Chilean Marxist

Description: This study is concerned with describing and analyzing the factors that led to the election and subsequent defeat of Salvador Allende. The research information was selected from leading books, periodicals, government documents, archives, and newspapers. The thesis presents the political history of Allende's rise to power, the social structure that made his victory possible, the development of major programs that facilitated his ascension and that made his decision inevitable, and, finally, an an… more
