"A wonderfully detailed account of an alien species in the U.S. . . . The author provides intriguing details of the natural history of the Cuban Treefrog in Florida and why it has been so successful in its new home."--Robert W. Henderson, curator of herpetology, Milwaukee Public Museum "The abundance of data cited in this study not only characterizes the Cuban Treefrog but establishes it as a model of a successful colonizer. This latter feature vastly increases the importance of this work by providing wildlife biologists with a list of characteristics that can be applied to other introduced species to determine the likelihood of successful establishment and expansion in non-native habitats--particularly those severely altered by human activity."--Robert Powell, Carnegie Museum of Natural History, author of A Key to the Amphibians and Reptiles of the Continental United States and Canada Florida has become a melting pot of invasive exotic species, especially those introduced from the Caribbean. Their expanding ranges and their impact on other species underscore a growing ecological problem faced in today's world of massive land-use changes and rapid transportation on a global scale. In one of the most detailed accounts of the ecology of an introduced species in the United States, Walter Meshaka presents the natural history of the Cuban Treefrog from the perspective of its phenomenal success, in terms of sheer numbers and geographic range, as a colonizer in South Florida and, in particular, the Everglades. For those interested in the natural history of the state and especially for herpetologists, ecologists, conservation biologists, and land managers, this work provides a readable and data-rich study on a timely issue. Meshaka discusses all facets of the natural history of the Cuban Treefrog in detail as well as the correlates of its successful colonization--for example, it colonized an environment that was nearly competitor-free, it ate its potential competitors, and it exploited human habitats. In light of Meshaka's findings, any hope of eradicating the Cuban Treefrog looks dim. The usefulness of this book extends well beyond mere description of the natural history of a single species. It supplies a methodology for evaluating and setting priorities for the threats facing Florida's amphibian and reptile populations and identifies the most vulnerable species, providing a base for management decisions. It also presents and interprets a large data set associated with patterns of colonization and predictions. Walter E. Meshaka, Jr., senior curator of zoology and botany for the State Museum of Pennsylvania in Harrisburg, was curator at Everglades National Park from 1995 to 2000. He has contributed numerous articles to Journal of Herpetology, Copeia, Florida Scientist, and other publications and is the coauthor of the forthcoming Exotic Amphibians and Reptiles of Florida.

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.

Invasive species are one of the major threats to biodiversity and understanding the effects any one invasive species has on members of its new ecosystem can help land managers decide how to best use their limited resources. This study attempted to show the effect Cuban Treefrogs (Osteopilus Septentrionalis) were having on native Florida hylids. For a year, Cuban Treefrogs were removed from three cypress domes and monitored in three other cypress domes, a change in the native population in the experimental domes was the eventual desired effect. Due to weather issues and low native hylid numbers no effect was shown, however due to environmental constraints an effect could not be ruled out either.

Exotic amphibians are often detrimental to native biotas. In Florida, the exotic Cuban Treefrog (Osteopilus septentrionalis) eats native frogs and may outcompete them for resources. Cuban Treefrogs thrive in disturbed areas and around buildings, and often breed in manufactured wetlands such as retention ponds and borrow pits. This study identified limnological, landscape, and biotic characteristics that discouraged pond use by Cuban Treefrogs and promoted use by native amphibian species. I sampled natural and manufactured ponds in Orange County, Florida, for one year, using standard methods to estimate the species richness and relative abundance of amphibians and their potential fish and macroinvertebrate predators. I determined the relationship between the presence of Cuban Treefrogs and twelve limnological (% vegetation, slope, pond age, pH, % dissolved oxygen, air temperature, water temperature, turbidity, conductivity, depth, perimeter, and area) and seven landscape characteristics (% canopy closure over ponds, building density, distance to nearest building, road density, distance to nearest road, distance to nearest forest stand, and % forest cover), plus five biotic factors (native amphibian richness and abundance, fish richness and abundance, and macroinvertebrate abundance). No relationship existed between native amphibian abundance or species richness and the presence or absence of Cuban Treefrogs. Ponds with a greater percentage of vegetation, large perimeters, and low pH and turbidity had greater native amphibian species richness. Cuban Treefrogs were more likely to be found in ponds with a greater percentage of aquatic vegetation and small perimeters. My results show that building large retention ponds containing low-turbidity water will restrict colonization by Cuban Treefrogs and maintain species richness of native amphibians.

Cuban treefrogs withstood much cooler temperatures than previously reported, and frogs from North Florida had consistently lower CTMins than frogs from Central and South Florida in both the presence and absence of acclimation. These results possibly indicate an ability of CTFs to adjust to the cooler temperatures in North Florida and continue their expansion northward and westward.

Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the “Homogocene” in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive – and frequently unpredictable – ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many “natural” areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.

Vertebrate invasive species are important ecologically, socially, and scientifically throughout much of the globe. However, the interdiction and options for management of invasive species are driven by localized regulation at the country or even state level and thus the management of species must be framed within that context. This book is focused around the management of invasive vertebrate species in the United States, although readers will find much of the material broadly applicable to invasive species in other regions. Vertebrate invasive species cause damage to agriculture, property, natural resources, and threaten human health and safety. However, most of these species occur in the United States resulting from human-mediated activities, often being released intentionally. For the first time, the wealth of scientific information about vertebrate invasive species in the United States is summarized and synthesized in a single volume to be easily accessible to ecologists and natural resource managers. With a focus on prominent terrestrial invasive species that have a history of policy and management and highlighting contemporary issues and management, this book consists of 18 chapters written by experts from across the United States. The first section of the book focuses on overarching policy and management topics associated with vertebrate invasive species; including biosecurity threats and risk assessment, policy and regulation, and the economics of their management. The second section provides in-depth reviews of noteworthy invasive mammals, birds, amphibians, and reptiles. After finishing this book, the reader should understand the complexity of managing invasive species, the unique challenges that each new species may present, and the steps forward that may decrease the impact of these species on the environment, human health, and the economy.

Most of the islands of the Caribbean have long histories of herpetological exploration and discovery, and even longer histories of human-mediated environmental degradation. Collectively, they constitute a major biodiversity hotspot – a region rich in endemic species that are threatened with extinction. This two-volume series documents the existing status of herpetofaunas (including sea turtles) of the Caribbean, and highlights conservation needs and efforts. Previous contributions to West Indian herpetology have focused on taxonomy, ecology and evolution, particularly of lizards. This series provides a unique and timely review of the status and conservation of all groups of amphibians and reptiles in the region. This volume introduces the issues particularly affecting Caribbean herpetofaunas, and gives an overview of evolutionary and taxonomic patterns influencing their conservation.

Although invasive species are considered to be a significant threat to native biodiversity, the impacts of very few nonindigenous species are well known. In this dissertation I describe the results of several studies evaluating the impacts of the presence of nonindigenous amphibians and reptiles in Florida. I conducted an analysis to assess the patterns and effects on biodiversity of the establishment of nonindigenous amphibians and reptiles in Florida at the county level. The richness of the 40 established nonindigenous amphibians and reptiles is not distributed evenly across the state, but instead is significantly greater in the southern part of the state and in counties with large human populations. These trends likely reflect the recent breakdown of historical barriers to invasion between Florida and the Caribbean region and the influence of human activities in the establishment of nonindigenous species. I also conducted several experimental case studies of the effects of the presence of the tadpoles of two invasive amphibians, the cane toad (Bufo marinus) and the Cuban treefrog (Osteopilus septentrionalis), in native Floridian tadpole communities. These studies indicated that B. marinus does not significantly affect native tadpoles through competition, while O. septentrionalis tadpoles outcompete and adversely affect native tadpoles, both in laboratory microcosms and naturalistic outdoor mesocosms. Larval O. septentrionalis also prey on native tadpoles, but this effect is probably not significant under natural conditions when alternative food is present. A mechanistic laboratory study indicated that the competitive effects of O. septentrionalis were mediated through exploitation competition with no evidence of interference competition. When keystone predators, eastern newts (Notophthalmus viridescens), were included in the experimental tadpole communities, the negative effects of O. septentrionalis tadpoles on native tadpoles were reduced significantly. Higher mortality of O. septentrionalis larvae suggests that newts preyed selectively on O. septentrionalis tadpoles, supporting their role as keystone predators. If general, this result suggests that keystone predators are important to the maintenance of diversity in invaded communities. Collectively, these results suggests that O. septentrionalis larvae may affect native amphibian populations in Florida through larval interactions, but these impacts may be limited by the presence of keystone predators.

In my first laboratory study, I compared the variation by species in frequency of refugia used when treefrogs were presented with the choice of either a PVC pipe refugia or a plant. I found that the native squirrel treefrog (Hyla squirella) rested in the pipe twice as often as on the plant, and Osteopilus septentrionalis used the pipes infrequently. The other two natives tested, green treefrog (H. cinerea) and pinewoods treefrog (H. femoralis), did not strongly favor either the PVC pipe refugia or the plant.
