These systems are sensitive to environmental factors, including social conditions, and may assist in relaying environmental signals to the HPG axis in a potentially broad range of taxa. In this study, we characterized expression of kisspeptin-system genes (kiss1, kiss2, kissr1, and kissr2), gnih, and gnrh1 in the brain of the bluehead wrasse (Thalassoma bifasciatum), an important teleost model of socially-controlled sex change. We analyzed cDNA sequences and examined transcript distributions in the brain using in situ hybridization (ISH) to determine if expression occurs in reproductively-relevant and conserved regions. Expression of kiss1 was detected in the habenula, lateral hypothalamic nucleus (LHn), and preoptic area (POA), while kiss2 was expressed in the dorsal hypothalamus, with sporadic signal in the POA. Expression of kissr1 was detected in the POA, habenula, and LHn, while kissr2 expression was widespread. Gnih mRNA was detected in the posterior periventricular nucleus (NPPv), and gnrh1 neurons localized to the POA. Neurons expressing kissr2 and gnih co-regionalized in the NPPv, while kissr1, kissr2, and gnrh1 co-regionalized in the POA. Double-label ISH revealed very close proximity between kissr1 and gnrh1 neurons, suggesting potential communication between the kisspeptin and GnRH1 systems through these interneurons. These expression patterns are generally conserved and suggest that if kisspeptins do signal GnRH1 neurons, the interaction is indirect, possibly through neurons adjacent to GnRH1. With this foundation in place, future studies can help determine the interactions among these systems and whether these peptides assist in transducing social changes into a shift from female to male sexual function.}, journal={JOURNAL OF CHEMICAL NEUROANATOMY}, author={Lamm, Melissa S. and Lamb, April D. and Klapheke, Brandon P. and Tyler, William A. and Godwin, John R.}, year={2022}, month={Apr} }

Evidence from Gonatodes antillensis and a Global Review of Squamate Reptiles Acting as Transport Hosts}, volume={60}, ISSN={["2162-4135"]}, DOI={10.3374/014.060.0103}, abstractNote={Abstract It is well known that reptiles can act as paratenic hosts for parasites that use mammals as their definitive hosts. However, studies of potential paratenic hosts in the Caribbean have been temporally restricted to only diurnal species of lizards, thereby neglecting a dominant component of the nocturnal reptilian community: geckos. Many gecko species are human commensals with activity periods that overlap temporally with those of domestic cats, making them prime candidates as potential transport hosts for cat parasites. However, no studies have reported geckos as paratenic hosts for felid parasites on any Caribbean island. Here we report the first records of subcutaneous oligacanthorhynchid cystacanths on the Venezuelan Coastal Clawed Gecko (Gonatodes antillensis) based on specimens collected in Curaçao and Bonaire. The cysts were identified as belonging to the genus Oncicola, likely those of Oncicola venezuelensis. This study reports these geckos as a new host record for oligacanthorhynchid cystacanths, as well as Curaçao and Bonaire as new geographic locales for these acanthocephalan parasites. We additionally provide a review of saurian cystacanths, comparing the restricted taxonomic focus of transport hosts in Caribbean islands to the distribution of paratenic squamate hosts both in the Neotropics and globally. We find evidence that the ability of squamate reptiles to act as transport hosts is a pervasive feature across their Tree of Life, suggesting that these animals may serve as important vectors for transporting parasites between intermediate and definitive hosts.}, number={1}, journal={BULLETIN OF THE PEABODY MUSEUM OF NATURAL HISTORY}, author={Dornburg, Alex and Lamb, April D. and Warren, Dan and Watkins-Colwell, Gregory J. and Lewbart, Gregory A. and Flowers, James}, year={2019}, month={Apr}, pages={55–79} }

Throughout the past century, the long-term persistence of this unique marine fauna has become increasingly threatened by regional atmospheric and, to a lesser extent oceanic, warming. Developing an understanding of how historical temperature shifts have shaped source-sink dynamics for Antarctica's teleost lineages provides critical insight for predicting future demographic responses to climate change. We use a combination of phylogenetic and biogeographic modelling to show that high-latitude Antarctic nearshore habitats have been an evolutionary sink for notothenioid species diversity. Contrary to expectations from island biogeographic theory, lower latitude regions of the Southern Ocean that include the northern Antarctic Peninsula and peripheral island archipelagos act as source areas to continental diversity. These peripheral areas facilitate both the generation of new species and repeated colonization of nearshore Antarctic continental regions. Our results provide historical context to contemporary trends of global climate change that threaten to invert these evolutionary dynamics.}, number={9}, journal={NATURE ECOLOGY & EVOLUTION}, author={Dornburg, Alex and Federman, Sarah and Lamb, April D. and Jones, Christopher D. and Near, Thomas J.}, year={2017}, month={Sep}, pages={1379–1384} }

 Geckos are among the most diverse radiations of lizards; however, the lack of baseline natural history data on the reproductive biology for many species creates a challenge for predicting their long-term persistence. This study aims to fill a gap in our understanding of the reproductive biology of an enigmatic nocturnal gecko endemic to the islands of Curaçao and Bonaire: Gonatodes antillensis. Using radiographs of specimens from natural history collections, we conduct the first investigation of the potential role of endolymphatic sacs in the reproduction of the species. We find that females have larger endolymphatic sacs than males, with further quantification of endolymphatic sac sizes between females with or without visible eggs supporting the hypothesis that calcium stores are built up in the early reproductive phase and depleted during the development of the egg. Additionally, we combined data on endolymphatic sacs sizes with examinations of gravidity to expand the known reproductive interval of the species into fall and winter months and suggest the possibility of year-round reproduction. Along with providing baseline data, our findings raise a new conservation concern for the species. The spread of the invasive gecko Hemidactylus mabouia has resulted in a notable decline in the abundance of Gonatodes antillensis across its native range. This decline has been attributed to Hemidactylus mabouia acting as both a competitor and possible predator of Gonatodes antillensis. However, stress can inhibit calcium uptake in endolymphatic sacs, and these findings raise the possibility that Hemidactylus mabouia may also be indirectly affecting the reproductive success of this species.}, number={1}, journal={BULLETIN OF THE PEABODY MUSEUM OF NATURAL HISTORY}, author={Lamb, April D. and Watkins-Colwell, Gregory J. and Moore, Jon A. and Warren, Dan L. and Iglesias, Teresa L. and Brandley, Matthew C. and Dornburg, Alex}, year={2017}, month={Apr}, pages={17–29} }

The factors that underlie population declines of reptiles are particularly nebulous, as these are often the least understood class of vertebrates in a given community. In this study, we assess correlations between feeding ecology and phenotypic traits of the Lesser Antillean endemic Dutch leaf-toed gecko, Phyllodactylus martini, along an urban gradient in the Caribbean island of Curaçao. There has been a marked decline of this species in developed habitats associated with the invasive tropical house gecko Hemidactylus mabouia. We find a correlation between aspects of locomotor morphology and prey in undeveloped habitats that is absent in developed habitats. Analyses of stomach contents further suggest that Phyllodactylus martini alters primary prey items in developed areas. However, changes in prey promote the overlap in foraging niches between Phyllodactylus martini and Hemidactylus mabouia, suggesting that direct resource competition is contributing to the decline of Phyllodactylus martini. In addition to competitive exclusion, we suggest that the urban extirpation of Phyllodactylus martini could also be attributed to a top-down control on population growth by Hemidactylus mabouia. Colonizations of walls put Phyllodactylus martini in direct contact with Hemidactylus mabouia increasing the chances for predation events, as evidenced by our observation of a predation event on a Phyllodactylus martini juvenile by an adult Hemidactylus mabuoia. In total, our results add to a growing body of literature demonstrating the threat that invasive synanthropic reptiles pose to endemics that might otherwise be able to cope with increased urbanization pressures.}, number={2}, journal={Bulletin of the Peabody Museum of Natural History}, author={Dornburg, A. and Lippi, C. and Federman, S. and Moore, J.
