2016 Krysko et al. New Verified Nonindigenous Amphibians and Reptiles in Florida through 2015, with a Summary of over 152 Years of Introductions.

Authors:

Abstract and Figures

More nonindigenous species occur in Florida, USA, than any other region worldwide and may threaten many of Florida's natural resources. The frequency of new reports mandates the need for regular updates. Herein, we use photographic and specimen vouchers in addition to literature records to provide updated information on verified nonindigenous amphibians and reptiles in Florida. Between our most recent summary in 2012 and the end of 2015, 38 additional species are known to have been intercepted (n=2) or introduced (n=36). We also update the invasion stage of seven species previously reported from Florida and report that five additional taxa are now established. In total 191 independent known introductions of 180 herpetofaunal taxa led to the establishment of 63 taxa. This suggests that one in three introduced herpetofaunal species becomes established in Florida. The pet trade represents the most common introduction pathway among these species and a single animal importer in Hollywood, Broward County, is the probable source for introduction of a quarter of all herpetofauna introduced to Florida.

In most instances, once introductions have been allowed to establish, no amount of money or effort can change the situation
much as is widely recognized for other lamentable and irreversible developments such as death, amputation, or the invention

... S outhern Florida is a known epicenter of exotic species introduction, especially for herpetofauna (Meshaka 2011), with more than 60 known established species as of 2015 (Krysko et al. 2016). At least four chelonian species are known to be established (Krysko et al. 2016), with several others documented but without confirmation of reproductive success (Stemle and Levine 2020;Stemle 2022;Weber et al. 2022). ...

Most of these are predominantly aquatic species; however, observations of a number of species of tortoises (Testudinidae) have been verified or vouchered; these include African Spurred Tortoises (Centrocheleys sulcata), Red-footed Tortoises (Chelonoidis carbonaria), Yellow-footed Tortoises (C. ...
... This prominence in the pet trade has led to numerous reports of released or escaped T. horsfieldii across the United States, including vouchers in Florida (Krysko et al. 2015). Krysko et al. (2010) directly encountered one individual in Bill Bags Cape Florida State Park during herpetofaunal surveys, indicating the potential for survival in southern Florida environments. ...
... Florida is a hotspot for invasions of a wide variety of taxa, and thus an ideal place to learn about the impacts of non-natives and how to manage them (Simberloff 1997;Krysko et al. 2016;Clements et al. 2019). Florida's diverse established non-native flora and fauna includes 1200 plant species, 37 bird species, and 63 herpetofauna (Simberloff 1977;Langeland and Stocker 2000;Pranty 2004;Krysko et al. 2016;Dawson et al. 2017;Florida Ornithological Society Records Committee 2021). ...

... This is the highest nonnative turtle species richness documented in any pond survey conducted in the Americas and is only rivaled by the high diversity of non-natives in a few Eurasian studies. We also encountered two non-native turtle species that had not been previously documented in Miami-Dade County, suggesting that further survey efforts would likely uncover additional non-native species (Krysko et al. 2011(Krysko et al. , 2016Stemle 2020;Stemle and Levine 2020). Our results demonstrate that many South Florida ponds are dominated by non-native turtles, which likely has negative impacts on native individuals (Lindeman 1999;Pearson et al. 2015;Ferri et al. 2020;). ...

Both aquatic and terrestrial habitat characteristics impact semi-aquatic turtle abundances, community composition, and sex ratios. South Florida is the global hotspot for non-native herpetofauna, but there is limited data on the turtle assemblage in this region. With the expectation that the turtle assemblage would reflect the high diversity of non-native herpetofauna species, we sought to identify both aquatic and terrestrial habitat characteristics that would support a higher percentage of native turtles in the community. We examined the relationships between a suite of habitat variables (pond characteristics, spatial structure of aquatic habitat, surrounding uplands) and turtle abundances, species richness, and sex ratios at 17 ponds in Miami-Dade County during 2019–2021. As expected, this turtle assemblage was dominated by non-natives, with 80% of individuals derived from six non-native species. This is the highest non-native turtle diversity documented in the Americas and is only rivaled by the high diversity of non-natives in a few Eurasian studies. We found that the abundance of native turtles was positively related to chlorophyll concentration, submergent vegetation density, pond area, and (surprisingly) high density urban habitat in the surrounding uplands. Road density in the surrounding uplands was also identified as an important habitat parameter, as it negatively affected both native turtle richness and the proportion of female turtles in each pond. Tracking the trajectory of the semi-aquatic turtle assemblage in this region heavily impacted by both urbanization and biotic invasions may foreshadow future changes in urban centers around the globe.
... Geckos are implicated as a major source of human salmonellosis in both their native and non-native ranges (Callaway et al. 2011;Nguyen et al. 2018), likely due to synanthropic species contaminating food and potable water with their feces. Florida is home to at least 14 established non-native gecko species, including Phelsuma grandis Gray 1870 and Gekko gecko (Linnaeus 1758) (Krysko et al. 2016); both species are widespread and synanthropic in parts of southern Florida (Krysko et al. 2019;Fieldsend et al. 2021), in contrast to Florida's only potentially native gecko Sphaerodactylus notatus notatus, which is cryptic, has a restricted range, and is predominantly found in natural habitat (Krysko et al. 2019). ...
... Our study represents the first research on Salmonella infection of wild reptiles in Florida for nearly half a century and provides the first evidence of Salmonella infection of wild geckos in the state. We hope that our findings stimulate further research into reptile-associated human salmonellosis in the state of Florida, particularly in the context of its diverse assemblage of non-native geckos (Krysko et al. 2016). ...

Wild geckos are a significant source of human salmonellosis. We swabbed the cloacas of 37 non-native synanthropic geckos (Gekko gecko, n = 16; Phelsuma grandis, n = 21) from southern Florida, USA, and assayed swab DNA extracts using quantitative polymerase chain reaction of the invA gene. Salmonella enterica was detected in both species with a pooled prevalence of 13.5% (5/37; 95% CI 5.3–27.1%), indicating the potential for zoonotic transmission. Implications for human health in the region are discussed.
... Ctenosaura similis (Gray) (Black Spiny-tailed Iguana) is a member of the most speciose genus of the Iguanidae family (Buckley et al. 2016) and one of the largest iguanids in the world (Bailey 1928, Krysko et al. 2016. It is abundant in its native range of Mexico and Central America, including Panama (Buckley et al. 2016, Forero-Medina et al. 2006, Pasachnik 2015. ...
... With 18 species of spiny-tailed iguanas, Ctenosaura is the most speciose genus (Buckley et al. 2016). Two species, Black Spiny-tailed Iguana and Ctenosaura pectinata (Weigmann) (Mexican Spiny-tailed Iguana), have been introduced in Florida with varying degrees of population sizes and spread, and pose conservation threats to native species (Enge 2006, Krysko et al. 2016). Here, we discuss C. similis, most commonly called the Black Spiny-tailed Iguana, but also referred to as Common Spiny-tailed Iguana, Black Iguana, Iguana Negra, and Garrobo Negra. ...

Ctenosaura similis (Black Spiny-tailed Iguana) is native to Mexico and Central America, where it is a wide-ranging habitat-generalist that is well adapted to human-altered environments. Black Spiny-tailed Iguana is considered one of the larger, heavier iguanid species, identified by its coloration and a series of enlarged whorls of spiny scales on the tail. Despite harvest rates for human consumption and the pet trade, Black Spiny-tailed Iguana is currently considered a species of least concern in their native range. There have been several introductions outside of their native range, many of which have become established due to their generalist nature. In Florida, Black Spiny-tailed Iguana was first introduced in 1979 and has been reported in 24 counties. Early removal efforts of other introduced iguanids such as Ctenosaura pectinata (Mexican Spiny-tailed Iguana) and Iguana iguana (Green Iguana) could serve as case studies to develop and implement eradication and management plans for this species. We provide a comprehensive summary of natural history findings on Black Spiny-tailed Iguana, including management methods and potential ecological impacts as an invasive species in the southeastern United States.
... While invasive species impact native species through a combination of direct and indirect effects and a few specific invasives have widespread ecosystem consequences, most introduced species have minimal documented impacts (Hardin 2007). In South Florida, there have been 191 independent known introductions of 180 herpetofaunal taxa that have led to the establishment of 63 taxa (Krysko et al. 2016). However, of those 63 taxa, only 25 (41%) have reached a status of being both geographically widespread and ecologically dominant according to Krysko et al. (2016). ...

Similarly, Florida has recorded more than 200 introduced fish species since the 1950s; however, a review (Schofield & Loftus 2015) categorized only 22 of them as being permanently established and widespread, and therefore possibly capable of causing substantive harm to the native ecosystem. ...

Invasive species are a chief threat to native biodiversity and are only becoming more common with human globalization. This creates a need to understand the patterns in invasion biology, including where invasions are most likely to occur, which species are most likely to establish and spread, and what are likely to be the most influential ecological consequences. We examine these questions through the lens of South Florida, the continental region with the most invasive species across the globe. First, understanding why South Florida has so many invasives and how they are distributed across South Florida helps us to understand where we can expect similar levels of invasion to occur. Second, understanding which species are most likely to establish, spread, and have the greatest ecological impact informs which invasions we should be most concerned about. Finally, the history of control efforts and their relative success can help guide future management practices. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 54 is November 2023.
