Ecological correlates of successful colonization in the life history of the Cuban treefrog, {\it Osteopilus septentrionalis\/} (Anura: Hylidae)

Ten correlates of successful colonization were tested and met in the life history of the Cuban treefrog in Florida and the Caribbean. Like many successful colonizing species of animals, the Cuban treefrog was highly fecund; reproduction was possible at a small body size in males (27.0 mm) and females (45.0 mm), and large females could lay large clutches and eggs throughout the year. Generation times were short in this species thereby accelerating the colonization process. Tadpoles and post-metamorphic individuals could exploit a wide range of physical conditions with respect to weather conditions and structure of the habitat. The Cuban treefrog occupied the terrestrial-arboreal niche which was only marginally exploited by other species in Florida. Habitat preference of the Cuban treefrog was for mesophytic forests and disturbed areas, and both habitats were found in native and introduced ranges. The ability to coexist with man further enabled the Cuban treefrog to expand its geographic range. A broad diet enabled the Cuban treefrog to exploit a wide range of prey species and sizes thereby alleviating an important constraint to colonization success. The Cuban treefrog was gregarious and vagile, thereby accelerating the process of dispersal which is crucial to the colonization process. Thus, many features in its life history enabled the Cuban treefrog to rapidly disperse and colonize, often in high population densities, many kinds of sites in its native and introduced range. Conformity to these correlates by the Cuban treefrog ultimately provides predictive power regarding the future colonization of this tropical frog. ^

Re -"interpreting" the conquest: European and Amerindian translators and go -betweens in the colonization of the Americas, 1492--1675

This dissertation aims to recover the lives and careers of those Amerindians and Europeans who voluntarily or involuntarily took on the role of intercultural interpreters in the contact, conquest, and early colonial period in the Americas between 1492 and 1675. It intends to prove that these so-called “marginal” figures assumed roles that went far beyond those of linguistic and cultural translators, and often had a decisive impact on early Indian-colonial relations. ^ In the course of my research, I consulted hundreds of published sixteenth- and seventeenth-century chronicles, narratives, and memoirs in my search for references to interpreters. I augmented these accounts with information derived from unpublished archival documents, drawn primarily from the Archivo General de Indias, in Seville, Spain. ^ I organized my findings in theme-driven chapters that begin with a consideration of the historiography of that subject. Each chapter is further subdivided into chronologically-arranged historical vignettes that focus on the interpreters who mediated between the Spanish, Portuguese, French, English and Dutch and the various Native American polities and cultures. ^ I found that colonial authorities and Amerindian communities alike recognized the absolute necessity of recruiting competent and loyal interpreters and go-betweens, and that both sides tried to secure their loyal service by means both fair and foul. Although pressured, pushed, and pulled in contrary directions, most interpreters recognized the pivotal position they held in cross-cultural negotiations and rarely remained passive pawns in the contests between the forces of domination and defense. ^ All across the Americas, interpreters used their linguistic and diplomatic skills, and their intimate knowledge of the “other” not simply to facilitate conquest or spearhead the opposition, but to transform themselves from “culture brokers” into “power brokers.” Many of the decisive events that shaped colonial-Indian relations turned on the actions of these culturally-ambiguous individuals, a fact bemoaned and begrudgingly acknowledged by most of the contemporary conquistadors, chroniclers, and colonial founders, and recognized by this author. ^
