Abstract
Background and Aim: Exotic pet snakes are more susceptible to infection, especially parasitic helminths than wild-caught. There is no comprehensive report on the prevalence of acanthocephalan parasite infection in Indonesian snakes. Therefore, this study aimed to estimate the prevalence rate and to identify the acanthocephalan infection in wild-caught Asian vine snake (Ahaetulla prasina) from the Mojokerto District, East Java, Indonesia.
Materials and Methods: A total of 60 snakes were collected from the local sellers in the Mojokerto District, East Java, Indonesia. Then, snakes were euthanized and necropsied to observe various predilections of acanthocephalan larval stage (cystacanth). Morphological identification of the cystacanth was conducted using the carmine staining method and microscopic examination.
Results: Acanthocephalan infection was recorded with a high prevalence rate of 80.06%. A total of 696 cystacanths were examined from the muscle, subcutaneous tissues, and visceral with 32.90, 16.37, and 50.71% intensity rates, respectively.
Conclusion: Acanthocephalan prevalence rate was recorded at 80.06% in this study. Constant disease monitoring is necessary, considering wild-caught Asian vine snakes were susceptible host and lack of data regarding parasitological surveys. Therefore, further studies are needed in new areas and various species of wild-caught snakes in Indonesia, because of the potential of parasitic helminth transmission between snake and other reptiles.

Abstract
Hemidactylus mabouia is one of the most successful, widespread invasive reptile species and has become ubiquitous across tropical urban settings in the Western Hemisphere. Its ability to thrive in close proximity to humans has been linked to the rapid disappearance of native geckos. However, aspects of Hemidactylus mabouia natural history and ecomorphology, often assumed to be linked with this effect on native populations, remain understudied or untested. Here, we combine data from ∂15N and ∂13C stable isotopes, stomach contents, and morphometric analyses of traits associated with feeding and locomotion to test alternate hypotheses of displacement between H. mabouia and a native gecko, Phyllodactylus martini, on the island of Curaçao. We demonstrate substantial overlap of invertebrate prey resources between the species, with H. mabouia stomachs containing larger arthropod prey as well as vertebrate prey. We additionally show that H. mabouia possesses several morphological advantages, including larger sizes in feeding-associated traits and limb proportions that could offer a propulsive locomotor advantage on vertical surfaces. Together, these findings provide the first support for the hypotheses that invasive H. mabouia and native P. martini overlap in prey resources and that H. mabouia possess ecomorphological advantages over P. martini. This work provides critical context for follow-up studies of H. mabouia and P. martini natural history and direct behavioral experiments that may ultimately illuminate the mechanisms underlying displacement on this island and act as a potential model for other systems with Hemidactylus mabouia invasions.
