“…Changes in thermal niches can reduce the number of active hours for a species (Pontes-da-Silva et al 2018), with effects on aspects of reproduction. For lizards of the genus Tropidurus, for example, local climatic conditions seem to influence minimum reproductive size (Gomides et al 2013). Populations of T. montanus have a high turnover rate of individuals, with considerable mortality in the first six months of life ).…”

Climate change is one of the greatest threats to biodiversity, especially for species of high altitudes. However, biodiversity conservation policies that consider mitigation strategies for long-term climate impacts are still scarce. To analyze the effects of climate change on lizards in tropical mountainous areas, we selected two species from Serra do Espinhaço (Brazil) with different thermoregulation strategies and distributions (Tropidurus montanus and Rhachisaurus brachylepis). Serra do Espinhaço mountain range is recognized as an important center of endemism and can act as a refuge for species that manage to survive climate change. We produce models of environmental suitability from bioclimatic, edaphic, and topographic variables, and create projections for the present and for the year 2070 under an optimistic (RCP 4.5) and a pessimistic (RCP 8.5) climatic scenario. The results indicate that both future climate scenarios foresee a reduction of areas of environmental suitability for the studied species, but especially for the restricted distribution one (R. brachylepis). Although our results indicate that the studied species are recorded in areas of integral protection that possess climatic stability, the future will see a reduction of areas with environmental suitability, especially under the pessimistic scenario.

“…Afterwards, we collected aliquots of liver for future molecular analysis, and those were conditioned in ethanol 100%. We fixed individuals according to the usual techniques described by Gomides et al (2013) and deposited in the amphibian's collection of Universidade Federal de Juiz de Fora (CAUFJF) (Appendix I) (Colect Permission ICMBio 65519-1). We also gathered data from specimens previously collected within the APABM and deposited in the herpetological collection of Museu de Zoologia João Moojen of the Universidade Federal de Viçosa (MZUFV).…”

Anurans of a protected area from Mantiqueira Complex, Atlantic Forest of Minas Gerais state, Brazil

The ecological domain of the Atlantic Forest holds a remarkable diversity of anurans with a great degree of endemism, most of which are distributed in high altitude areas, mostly represented by the mountains along the Mantiqueira Complex and Serra do Mar. Despite its biological importance, the region still shows a gap of sampling concerning the amphibians. Thus, we present the first systematic survey of the anuran fauna from Área de Proteção Ambiental Boqueirão da Mira (APABM), in the region of Zona da Mata, Minas Gerais state, Brazil. Two fieldwork expeditions were performed where fifteen sample points were inventoried through active night search and day audiovisual survey in breeding and foraging sites. The anuran fauna of the APABM presented 43 species distributed in 12 families, with the Hylidae family being the richest (17 species). Besides, four species had their distribution increased due to our findings (Hylodes perere, Physalaemus rupestris, Bokermannohyla ibitipoca and Ololygon cosenzai), all of them as endemic to the Mantiqueira Complex. This study revealed that the APABM has a great diversity of anuran species, more representative than adjacent regions such as the Parque Estadual Ibitipoca and close to the richness presented for the Parque Estadual Serra Negra da Mantiqueira. This work demonstrates the great importance of the APABM for conservation, highlighting it as an area of high diversity of the regional anuran species.

“…The specimens used for locomotor behavior analysis were euthanized after the experiments following Gomides et al (2013). All specimens used in this study are deposited at the CHUFJF-Reptiles with the deposit numbers: 205, 1423, 1473, 1643, 1646, 1649, 1650, 1731, 1866 and 1867. Body size measurement of the specimens were performed using a tape measure and a precision digital pachymeter, since they are fixed in a standard way for specimens with serpentiform bodies -"coiled"; due to the occurrence of caudal autotomy in some analyzed specimens, only the snouth-cloacal length (SVL) was measured.…”

There are few studies related to the biological and ecological aspects of the glass snake, a limbless lizard and with a wide geographic distribution. The aim of this study was to analyze the locomotion mode of specimens of Ophiodes cf. fragilis in different substrates and to investigate the morphological adaptations associated with this type of behavior. We observed that the analyzed specimens presented slide-push locomotion modes and lateral undulation in different substrates, using their hind limbs to aid locomotion in three of the four substrates analyzed. The bones of the hind limbs (proximal -femur -and distal -tibia and fibula) were present and highly reduced and the femur is connected to a thin pelvic girdle. Our data support that hind limbs observed in species of this genus are reduced rather than vestigial. The costocutaneous musculature was macroscopically absent. This is the first study of locomotor behavior and morphology associated with locomotion in Ophiodes, providing important information for studies on morphological evolution in the genus.
