Wind Decreases Microhabitat and Body Temperatures in Populations of Endangered Brazilian Sand Lizards Herpetological Conservation and Biology, 2025
Feeding Habits, Microhabitat Use, and Daily Activity Cycle of Adenomera marmorata (Anura, Leptodactylidae) in Two Brazilian Atlantic Forest Remnants Thiago Maia-Carneiro, Thiago Arnt Dorigo, Mara Cíntia Kiefer, Monique Van Sluys, Carlos Frederico Duarte Rocha South American Journal of Herpetology, 2021 We investigated daily activity, microhabitat use, and feeding habits of the anuran Adenomera marmorata in two Brazilian Atlantic forest remnants: Estação Ecológica Estadual Paraíso (EEEP) and Reserva Ecológica de Guapiaçu (REGUA). Most individuals were active at dusk (EEEP: n = 5 or 62.5%; REGUA: n = 16 or 45.7%; populations pooled: n = 21 or 48.8%) and nocturnally (EEEP: n = 3 or 37.5%; REGUA: n = 17 or 48.6%; populations pooled: n = 20 or 46.5%); however, individuals were encountered during the day (EEEP: n = 0; REGUA: n = 2 or 5.7%; populations pooled: n = 2 or 4.7%). The microhabitat used most by the anurans was the leaf litter of forest floor (EEEP: n = 8 or 80.0%; REGUA: n = 33 or 94.3%; populations pooled: n = 41 or 91.1%). In EEEP, in numerical terms, mainly isopods (33.33%) and ants (22.22%) composed the diet of A. marmorata. Volumetrically, Isopoda (77.37%) was the most important item. In terms of frequency of occurrence, isopods, and ants, both consumed by 30% of the individuals, were the most relevant food items. In REGUA, numerically, individuals mainly consumed ants (23.26%) and isopods (20.93%). In volumetric terms, individuals predominantly ingested isopods (56.57%). The food items most commonly consumed by individuals in REGUA were isopods (40.63%) and ants (37.50%). Adenomera marmorata ingested 8 different types of food in EEEP and 14 in REGUA, feeding on a significantly higher number of food items in REGUA than in EEEP. The populations also differed in diet composition in volumetric terms, showing that food consumption can vary between populations, which might result from differences in local food availability and individual morphological characteristics. Adenomera marmorata might be able to forage opportunistically or selectively depending on the prey.
Diverging temporal and thermal niche dimensions favor syntopy of Tropidurus hispidus and Tropidurus semitaeniatus (Squamata: Tropiduridae) Thiago Maia-Carneiro, Carlos Frederico Duarte Rocha Biologia, 2021 Divergences in ecological niche dimensions favor the coexistence of species in syntopy. Supposedly, closely related species face stronger pressures to differ in dimensions of niches. Integration among temporal, spatial and thermal niche dimensions is relevant for lizards because it allows proper regulation of body temperatures, which has consequences for their physiology and ecology. Here, we investigated temporal (daily activity) and thermal (body and microhabitat temperatures) niche dimensions and thermoregulation of Tropidurus hispidus and T. semitaeniatus . We hypothesized that divergences of niche dimensions would favor their local coexistences (syntopy). Tropidurus hispidus and T. semitaeniatus had similar lengths of daily activity cycles, but differed in movement rates along the day (start of the activities; hours of activity peaks; periods of greater inactivity). Activity rates and body temperatures of the lizards reflected phylogeny and thermal conditions. For both species, microhabitat temperatures and sunlight were sources for thermoregulation. Tropidurus semitaeniatus used warmer microhabitats than T. hispidus , but the species had similar body temperatures. Body sizes did not influence body temperatures, presumably because of effective behavioral thermoregulation allowing maintenance of body temperatures under appropriate ranges. Levels of active or passive thermoregulation varied depending of the thermal source (air and substrate temperatures). To thermoregulate, lizards raised up or brought down their bodies and increased or decreased levels of body flattening over substrates and shuttled across microhabitats with different temperatures and levels of sunlight. Along the day, T. hispidus used mainly partially shaded microhabitats and T. semitaeniatus used mostly full sunlight. Temporal and thermal niche dimensions of T. hispidus and T. semitaeniatus differed in ways that favor their syntopy.

Amphibians and reptiles from the parque nacional da tijuca, brazil, one of the world’s largest urban forests Thiago Arnt Dorigo, Carla Costa Siqueira, Jane C. F. Oliveira, Luciana Ardenghi Fusinatto, Manuela Santos-Pereira, et al. Biota Neotropica, 2021 The Parque Nacional da Tijuca in Rio de Janeiro, Brazil, is considered to be one of the world’s largest urban forests, however no systematic inventory of its herpetofauna is available. In the present study, we surveyed the amphibians and reptiles of this park to assess its species composition (including secondary data) and obtain estimates of species richness and abundance. We conducted active searches (460 hours) between January 2013 and December 2015. We identified the taxa endemic to either the Atlantic Forest or Rio de Janeiro state, and verified the conservation status of each species in the international, Brazilian, and state red lists. We also estimated the species richness and sampling sufficiency by rarefaction curves and Bootstrap richness estimator, and analyzed the distribution of the species abundance in Whittaker plots. We recorded 3,288 individuals over 36 months, representing 24 species of amphibians and 25 reptiles. The cumulative species curves, rarefaction, and the richness estimated indicated that sampling effort was adequate. Species abundance adjusted to the log-series model in both amphibians and reptiles. The four most abundant amphibians represented 70% of the individuals recorded in this group, while the two most abundant reptiles represented 60% of the total individuals. The inclusion of the secondary data raised the number of amphibian species to 38, and the number of reptiles to 36. Approximately 80% of the amphibian species and 28% of the reptile species recorded are endemic to the Atlantic Forest, and six of the amphibian species are endemic to Rio de Janeiro state. Six amphibian species and one reptile species are classified under some threat of extinction, and two reptile species were exotic. The considerable diversity of the herpetofauna of the Parque Nacional da Tijuca, which includes endemic and threatened species, reflects the effectiveness of the reforestation of this protected area and emphasizes the importance of its conservation.
A summary of reptile and anuran amphibian species from brazilian sandy coastal plains: 31 years of sampling efforts of the “laboratório de ecologia de vertebrados, universidade do estado do Rio de Janeiro” C. F. D. Rocha, C. M. Militão, D. Vrcibradic, M. Van Sluys, J. Pereira-Ribeiro, et al. Brazilian Journal of Biology, 2021 Although currently there is already a set of studies regarding ecological aspects of some particular reptile and amphibian species living in Brazilian sandy coastal plains (including the so-called “restinga” and “campo nativo” habitats), there is comparatively few information on the species composition usually associated to these environments. During 31 years (1988-2019) of herpetological studies carried out in sandy coastal plains environments by our research team of the Laboratory of Vertebrate Ecology (Department of Ecology, Universidade do Estado do Rio de Janeiro, in Rio de Janeiro Brazil) we have surveyed reptile and amphibian communities and performed different studies with similar methods in 70 sites from 10 different states along the Brazilian coast. Our surveys resulted in records of 87 species of reptile (five turtles, two crocodylians, six amphisbaenians, 36 lizards and 39 snakes) from 24 families, and 77 species of anuran amphibians from nine families. We have studied multiple natural history topics for anurans and reptiles which resulted in the publication of some specific ecological studies, especially regarding some species, encompassing population and community ecology, foraging and feeding habits, species activity, thermoregulation, reproduction, use of microhabitats, and parasitism by ecto and endoparasites. Our results along these three decades have also contributed for the description of four new lizard species (Ameivula nativo, Glaucomastix littoralis, G. abaetensis and G. itabaianensis). Our studies constitute an important contribution to the knowledge of the ecology of anuran amphibians and reptiles in these ecosystems, as well as to the conservation of sandy coastal plains environment. The checklist presented in this study, based on our records of sandy coastal plains herpetofauna, provides for many localities along the Brazilian coast, the needed knowledge on species occurrence, including the presence of endemic and/or endangered species, which can be of value for many conservation actions.
High prevalence and intensity of infestation of Eutrombicula alfreddugesi (Acarina: Trombiculidae) on Tropidurus torquatus (Squamata, Tropiduridae): effects of body size and on body condition across ten populations along the Brazilian coast Carlos Frederico Duarte Rocha, Mônica Cunha-Barros, Vanderlaine Amaral Menezes, Davor Vrcibradic, Mara Cíntia Kiefer, et al. Biologia, 2020 We investigated the infestation of Eutrombicula alfreddugesi mites on Tropidurus torquatus lizards across ten coastal populations in Brazil to evaluate variations among localities and relationships with intrinsic features of hosts (body size and body condition). For each population, we calculated the prevalence of infestation and the mean number of mites per host (mean intensity of infestation). Lizards from all populations were infested by mites, with prevalence ranging from 95.6 to 100%. Mean intensities of infestation also were always high, ranging from 55.3 ± 88.8 to 280.9 ± 208.2 mites per lizard. The lizard body regions most intensely used as microhabitat by mites were the axillae and neck (which bear “mite pockets” in T. torquatus). In most populations, the number of mites tended to increase with the body size of hosts. The body condition of hosts and the intensity of infestation were positively correlated, considering the total sample (i.e. lizards of all populations pooled). The main microhabitats (i.e., body regions) used by E. alfreddugesi on T. torquatus represented total intensities of infestation, suggesting that counting mites on these body regions provide a useful index to estimate the overall intensity of infestation. Lizards are suitable and predictable resources for parasitic mites, which take advantage of ecological and morphological features of host individuals and species, with large body sizes, imbricated and keeled scales, and presence of skin folds and mite pockets favoring occupation and high intensities of infestation by mites.
Body orientation for thermoregulation and daily activity cycle of mabuya macrorhyncha (Squamata: Scincidae) Thiago Maia-Carneiro, Gisele R. Winck, Mariana Rodrigues Pereira, Carlos Frederico Duarte Rocha Zoologia, 2018 We investigated the daily activity and thermoregulatory body orientation of Mabuya macrorhyncha (Hoge, 1947), a lizard species that occurs in the Brazilian Atlantic Forest. We conducted this investigation in a sandy coastal dune remnant (“restinga” ecosystem) in Grussaí, state of Rio de Janeiro, Brazil, during the summer. The daily activity cycle of the lizards started around 6:00 am and ended before 7:00 pm. This is longer than observed in other populations of M. macrorhyncha (approximately 7:00 am to 5:00 pm). The activity cycle of the lizards was bimodal, with the first peak between 6:00 and 11:00 am and the second from 2:00 to 7:00 pm. This contrasts with observations on other populations of this species, which revealed an unimodal pattern. The mean body temperature of M. macrorhyncha in Grussaí was 34.2 ± 1.5 °C, which was comparatively higher than observed in other populations of the species. The differences in the daily activity and of body temperature of these lizards between our study and previous studies on this species may reflect environmental thermal conditions. The mean air and mean substrate temperatures when individuals were active were 27.8 and 30.5 °C respectively. Lizard orientation was significantly correlated with the direction of the solar incidence, suggesting that solar radiation, and particularly behavioral adjustments that maximize exposure to the sun, are important for the thermoregulation of M. macrorhyncha. Circular structures at the site, such as bromeliads, offer microhabitats with different orientations to the sunlight, favoring lizard thermoregulatory behaviors.
