“…The new records extend the distribution in about 150 km linear to the south from the nearest known locality (municipality of Caldas, department of Antioquia) (Vásquez-Restrepo & Lapwong, 2018). However, the records of this species seem to be isolated and further fieldwork should be done to define if the species is well established and if it occupies a different niche with respect to native geckos (Perella & Behm, 2020). With our records, H. garnotii is currently known in six localities in the Colombian Andes (Figure 1B) (Table 2S, https://www.raccefyn.co/index.php/raccefyn/article/view/1356/3037).…”

The study of the introduction of exotic species in Colombia has been a trending topic in the last decade due to their effects on local diversity. The records of exotic reptile species of the genus Hemidactylus have increased based on museum vouchers and fieldwork. However, there are still plenty of information gaps regarding their current distribution in the country. Similarly, there is limited information on unusual reptile distributions caused by human transport inside the country. Here, we present an update to the distribution of the exotic house geckos Hemidactylus frenatus, H. garnotii, and H. mabouia based on several new localities and historical records. We also present an atypical record of the golden spectacled tegu Gymnophthalmus speciosus in paramo ecosystems from the Central Andes of Colombia, almost 2000 meters above the upper elevational known limit for this species. The distribution update shows that H. frenatus is widely distributed in 30 of the 32 departments of Colombia with no records for Chocó and Guainía. H. garnotii is currently known only from the Cauca River basin of the departments of Antioquia, Caldas, and Risaralda, while H. mabouia, previously known from the Amazon basin of the country, is now reported for the Andean region. Finally, Gymnophthalmus speciosus presence in a paramo ecosystem, considered unusual as it is not part of its distribution area, was probably the result of an accidental transport from a typical lowland locality (below 1000 meters above sea level.

“…Such economic isolation metrics have been based on trade, tourism, and size of an island's economy (e.g., Ficetola & Padoa-Schioppa 2009;Helmus et al 2014;Capinha et al 2017;Rojas-Sandoval et al2020). For example, since herps are often introduced through shipping cargo (Kraus 2009;Perella & Behm 2020), economic isolation metrics built on shipping can explain introduced herp species richness well (e.g., Helmus et al 2014). Economic isolation also effects native species richness because introductions can rescue declining native populations (e.g., Richmond et al 2021).…”

“…However, most changes to island habitats (Hedgeset al 2018) and species diversity occurred after 1950 (Helmuset al 2014). Today, herps are frequently introduced to islands (Kraus 2009;Powell et al 2011;Perella & Behm 2020) and pervasive deforestation and land development have changed habitat diversity (Hedges 2011). Only 9 of 827 native Caribbean herp species assessed by the IUCN are extinct, but 153 are critically endangered (IUCN 2021).…”

Classic ecological theory must explain effects of humans on biodiversity to be more applicable today. We contemporized island biogeographic theory providing native, introduced, and total species richness relationship expectations with natural and anthropogenic metrics of habitat diversity (geographic and economic area) and isolation from source pools (geographic and economic isolation). We assessed these expectations across Caribbean island herpetofauna clades. As expected by the contemporized theory, natural habitat diversity metrics exhibited positive relationships with native and introduced richness, strengthening positive total richness-area relationships. Geographic isolation exhibited negative relationships with native and positive relationships with introduced richness, weakening total richness-isolation relationships. Economic area and isolation exhibited negative and positive relationships, respectively, with native richness but positive and negative relationships, respectively, with introduced richness. Total richness relationships with economic area and isolation were strongest in clades with many introductions. As more species spread globally, these contemporary expectations will increasingly predict Anthropocene island biogeography.

“…On T he exotic pet trade has been identified as the primary introduction pathway for several populations of invasive vertebrates (García-Díaz et al 2017;Lockwood et al 2019), including a number of commonly traded exotic reptiles (Mo 2019a;Perella and Behm 2020). Australia is an island continent with jurisdictions prohibiting the importation and private keeping of non-native reptiles.…”
