ABSTRACT Fernando de Noronha is an oceanic archipelago in the Atlantic Ocean, 345 km offshore from the Brazilian coast. It comprises 21 islands and islets, of which the main island (FN) is 17 km2 with a rapidly growing tourism industry in the last decades. Despite being a protected area and bearing Ramsar and UNESCO World Heritage site status, it is threatened by multiple terrestrial invasive species since its colonisation in the early 16th century. Invasive species and the increasing tourism contributes to a list of at least 15 endangered or critically endangered species according to IUCN criteria. The black and white tegu (Salvator merianae) is the largest lizard in South America, occurring in most of the Brazilian territory and reaching up to 8 kg and 1.6 m from head to tail. -

KAEFER 92 Abstract: Blood samples from 330 lizards of 19 species were collected to investigate the (2) occurrence of haemoparasites. Samplings were performed in areas of upland (terra- 92(2) fi rme) forest adjacent to Manaus municipality, Amazonas, Brazil. Blood parasites were detected in 220 (66%) lizards of 12 species and comprised four major groups: Apicomplexa (including haemogregarines, piroplasms, and haemosporidians), trypanosomatids, microfi larid nematodes and viral or bacterial organisms. Order Haemosporida had the highest prevalence, with 118 (35%) animals from 11 species. For lizard species, Uranoscodon superciliosus was the most parasitised host, with 103 (87%; n = 118) positive individuals. This species also presented the highest parasite diversity, with the occurrence of six taxa. Despite the diffi culties attributed by many authors regarding the use of morphological characters for taxonomic resolution of haemoparasites, our low- cost approach using light microscopy recorded a high prevalence and diversity of blood parasite taxa in a relatively small number of host species. This report is the fi rst survey of haemoparasites in lizards in the study region. -

Lacher August 2009 Major Subject: Wildlife and Fisheries Sciences iii ABSTRACT Amphibian and Reptile Trade in Texas: Current Status and Trends. (August 2009) Heather Lee Prestridge, B.S., Texas A&M University Chair of Advisory Committee: Dr. Lee A. Fitzgerald The non-game wildlife trade poses a risk to our natural landscape, natural heritage, economy, and security. Specifically, the trade in non-game reptiles and amphibians exploits native populations, and is likely not sustainable for many species. Exotic amphibian and reptile species pose risk of invasion and directly or indirectly alter the native landscape. The extent of non-game amphibian and reptile trade is not fully understood and is poorly documented. To quantitatively describe the trade in Texas, I solicited data from the United States Fish and Wildlife Service’s (USFWS) Law Enforcement Management Information System (LEMIS) and Texas Parks and Wildlife Department’s (TPWD) non-game dealer permits. -
FWC BIOPROFILE for the ARGENTINE BLACK and WHITE TEGU ( Tupinambis Merianae )
FWC BIOPROFILE FOR THE ARGENTINE BLACK AND WHITE TEGU ( Tupinambis merianae ) 1. CLASSIFICATION a. Taxonomy Class Reptilia (reptiles) Order Squamata (snakes and lizards) Suborder Lacertilia (lizards) Family Teiidae (teiids or whiptails) Subfamily Tupinambinae (tupinambids) Genus Tupinambis (tegus) The Argentine black and white tegu, Tupinambis merianae (Duméril and Bibron 1839), is 1 of 7 currently recognized tegu species. There is a northern clade of tegus distinguished by a single loreal scale that occurs in northern South America and Amazonia, and a southern clade distinguished by 2 loreal scales that occurs primarily south of Amazonia (Fitzgerald et al. 1999). Tupinambis merianae is a member of the southern clade, along with the red tegu, T. rufescens (Günther 1871), and T. duseni Lönnberg 1910. The northern clade presently contains T. teguixin (Linnaeus 1758), T. longilineus Ávila-Pires 1995, T. quadrilineatus Manzani and Abe 1997, and T. palustris Manzani and Abe 2002. The taxonomy of Tupinambis has been the subject of much confusion (see Péres and Colli 2004). Until recently, T. merianae was referred to as T. teguixin, and the Amazonian form with a single loreal scale (i.e., T. teguixin ) was referred to as T. nigropunctatus Spix 1825 (Boulenger 1885, Peters and Donoso-Barros 1970). Presch (1973) realized that T. nigropunctatus was not a good name, but he recognized only 2 species; T. teguixin referred to all tegus except T. rufescens , regardless of the number of loreal scales. Ávila-Pires (1995) concluded that T. nigropunctatus should be renamed T. teguixin , and T. teguixin should be renamed T. merianae . In the scientific literature from approximately 1970 through 1995, T. -
Salvator Merianae (Black and White Tegu) Scavaging Around the Nests of Fregata Magnificens (Frigatebird)
NATURAL HISTORY NOTE The Herpetological Bulletin 135, 2016: 36-37 Salvator merianae (black and white tegu) scavaging around the nests of Fregata magnificens (frigatebird) EDELCIO MUSCAT¹*, FABIO OLMOS & ELSIE ROTENBERG¹ ¹Projeto Dacnis. Estrada do Rio Escuro 4754, CEP 11680-000, Ubatuba, São Paulo, Brazil *Corresponding author email: [email protected] The black and white tegu Salvator merianae is a sizable lizard (120-140 cm TL, 2.5-7 kg) with the largest range in its genus, occurring in the north of Argentina, Uruguay, Paraguay and in most of Brazil outside of the Amazon (Péres Jr., 2003). Adaptable, it occupies most of the South American biomes, both in forest and in open habitats (Péres Jr., 2003). Tegus are generalists that feed on a wide variety of invertebrates and vertebrates, carrion, fruit and fungi (e.g. Sazima & D’Angelo, 2013). The adults are hunters capable of capturing mammals and birds, and are known predators of nests (Sazima & Haddad, 1992; 1996; Cicchi, 2006). S. merianae occurs naturally in several coastal islands in the south-southeast Brazilian seaboard, where it can cohabit with some species of marine birds. Here we report the first observations of S. merianae individuals foraging in a breeding colony of frigatebirds Fregata magnificens Figure 1.

Reed1 Invasive reptilian predators can have substantial impacts on native species and ecosystems. Tegu lizards are widely distributed in South America east of the Andes, and are popular in the international live animal trade. Two species are established in Florida (U.S.A.) - Salvator merianae (Argentine black and white tegu) and Tupinambis teguixin sensu lato (gold tegu) – and a third has been recorded there— S. rufescens (red tegu). We built species distribution models (SDMs) using 5 approaches (logistic regression, multivariate adaptive regression splines, boosted regression trees, random forest, and maximum entropy) based on data from the native ranges. We then projected these models to North America to develop hypotheses for potential tegu distributions. Our results suggest that much of the southern United States and northern México probably contains suitable habitat for one or more of these tegu species. Salvator rufescens had higher habitat suitability in semi-arid areas, whereas S. merianae and T. teguixin had higher habitat suitability in more mesic areas. We propose that Florida is not the only state where these taxa could become established, and that early detection and rapid response programs targeting tegu lizards in potentially suitable habitat elsewhere in North America could help prevent establishment and abate negative impacts on native ecosystems. -

Rochford Ecological Plasticity and the Future of the Argentine Giant Tegu (Salvator merianae Dumeril and Bibron, 1839) in the Southeastern US Walter E. Meshaka Jr.1,*, Frank J. Mazzotti2, and Michael R. Rochford2 Abstract - Salvator merianae (Argentine Giant Tegu) is an invasive exotic species estab- lished in 2 as yet unconnected populations in central and southern Florida. Despite intense trapping, this mid-level carnivore remains well-established in a portion of extreme southern mainland Florida where it was first released 20 y ago. High fecundity, nest-guarding, rapid growth to large body size, and broad trophic width by which it negatively impacts wildlife contribute to its success as a colonizing species. Native to more temperate habitat, it experi- ences a defined winter and summer in South America unlike the wet–dry seasons ofsouthern Florida. We conducted a qualitative comparison of key life-history traits from source areas to those of southern Florida that provided a measure of its ecological plasticity and formed the basis for expectations associated with northward expansion. Our examination of 1168 specimens collected during 2011–2017 revealed an overlap between the sexes in timing of fat storage prior to brumation and late-winter–early-spring peak in gonadal size. Females were ovigerous during March–May and possibly June, and clutch size averaged 28.6 eggs. Hatching was possible during May–August, and both sexes reached sexual maturity by 2 y of age. In this subtropical system, length of seasonal activity, gonadal cycles, and size and age at sexual maturity differed from those of source areas, indicative of the degree of plasticity among these traits over a short period of time. -
