Abstract: The Indo-Pacific Gecko, Hemidactylus garnotii Duméril & Bibron, 1836, is a species of house gecko native to Southeast Asia and Pacific Islands. As with many of its congeners, this gecko species has been accidentally introduced to other parts of the world. In January 2018, several photographs of “ H. frenatus ” from Colombia posted in iNaturalist.org, were noticed to have some morphological features related to H. garnotii . This discrepancy led us to inspect museum specimens and to confirm the presence of H. garnotii for more than a decade in Colombia.

Abstract: The 2019–2020 Australian megafires were unprecedented in their intensity and extent. These wildfires may have caused high mortality of adult broad‐headed snakes Hoplocephalus bungaroides which shelter inside tree hollows during summer. We evaluated the impacts of two high‐intensity wildfires (2002 Touga Fire and 2020 Morton Fire) on a broad‐headed snake population in Morton National Park, south‐eastern Australia. We analysed a 29‐year mark–recapture data set to estimate survival rates of adults in years with and without wildfires, and with and without human disturbance to rock outcrops. To examine the short‐term effects of fire on occupancy, we analysed presence–absence data collected from 25 sites during 2019 and 2020. Estimates of occupancy were higher for 2020 (0.93 ± 0.09) than for 2019 (0.66 ± 0.14), while detection rates were constant (0.40 ± 0.06). Over the period 1992–2020, the best supported Cormack–Jolly–Seber model was one in which adult survival rates were high and stable (0.81 ± 0.04), but were 23% lower in years when humans disturbed rocks (0.63 ± 0.08). A model in which adult mortality was 20% higher in years with human disturbance and 14% higher in years with wildfires was also supported. Estimates of abundance revealed that the population declined by 34% after the Touga Fire, and 26% after the Morton Fire. Over the 29‐year study, the population has declined by 60%. Our results highlight how mortality events from wildfires need to be evaluated in the context of other threatening processes. For this population, the removal of snakes and associated habitat disturbance poses a more serious threat to population viability than infrequent wildfires.

Abstract: The Asian house gecko ( Hemidactylus frenatus ) is a tropical invasive species that has established and spread throughout several temperate regions around the world. In some invasive species, rapid thermal acclimation (thermal hardening) may contribute to their success in occupying a wide range of climates. In this study, we investigated whether invasive house geckos from southeastern Australia show differing thermal hardening responses than in iduals from the native range in Thailand. In the laboratory, we measured the basal heat tolerance (CT max ) of the geckos and their heat hardening response after being subjected to the second thermal stress after 1, 3, 5, 7, 9, or 11 hours. When geckos had recovered, we measured their basal cold tolerance (CT min ) and cold hardening response over the same time intervals. We then explored whether hardening responses differed between populations or among time intervals. We found that basal heat tolerances did not differ between populations, but geckos from Australia had lower cold tolerance than geckos from Thailand. The magnitude of the heat hardening was similar between populations, but the introduced geckos had a higher magnitude of cold hardening. The native geckos could maximize their cold tolerance capacity for only 0.6 °C, comparing to 0.9 °C of the introduced geckos. Also, geckos from Australia exhibited faster responses to thermal stress than did geckos from Thailand. Maximum thermal tolerances as a result of hardening responses peaked within three hours after thermal stress in Australian geckos (adjusted means = 44.0 °C for CT max and 9.9 °C for CT min ) and at five hours after thermal stress in Thai geckos (adjusted means = 44.2 °C and 10.2 °C, respectively). The plasticity in the thermal hardening of the invasive gecko should enable it to survive rapid temperature fluctuations, especially cold snap, that occasionally occur in temperate regions.
