Abstract:

Abstract Body temperature is important in determining individual performance in ectotherms such as lizards. Environmental temperature decreases with increasing altitude, but nevertheless many lizards inhabit high-altitude environments. The ‘thermal melanism hypothesis’ proposes that a dark dorsal coloration enables darker individuals to heat up faster because they absorb more solar radiation and thus being darker may be advantageous in cold habitats. The aim of the present study is to evaluate how heating rate, cooling rate and net heat gain vary with body size and dorsal skin coloration in Sc

Abstract:

The thermal ecology of a high-altitude lizard, Sceloporus scalaris, was investigated in the Chiricahua Mountains of southeastern Arizona, where the lizards are active on sunny days throughout the year. Mean body temperature was 32.6 °C (range 12.6–39 °C) and mean air temperature was 20.2 °C (range 5.2–36.4 °C). The slope of the body temperature versus air temperature regression was 0.23. Monthly differences in body temperature were observed, with the highest body temperatures observed in early summer. Lizards at three study sites with differing slope and vegetative cover had different mean bod

Abstract:

We studied the thermal ecology of Sceloporus grammicus occurring in very different thermal environments at 3700 and 4400 m elevation on the Iztaccihuatl Volcano, Mexico. Despite differences in the thermal environment between study sites, individual lizards maintained similar active body temperatures (around 31.5 °C). Similar body temperatures at the two study sites probably result in differences in the cost of the thermoregulatory behavior. Lizards at the high-altitude site, an open area with few predators or competitors, presumably incur a lower thermoregulatory cost than those at the low-alt

The thermal requirements of ectotherms may vary among species due to adaptation to different thermal environments. Nevertheless, some of these requirements are evolutionarily conserved, leading organisms to compensate behaviorally for harsh environmental conditions. High-mountain systems provide temperature gradients that allow for studies of evolutionary and plastic variation in thermal ecology under natural conditions. We evaluated the thermoregulation strategies of Sceloporus grammicus Wiegmann, 1828 at three points (2600, 3100, and 4150 m above sea level) along an altitudinal gradient. We

Abstract:

Mountain ecosystems act as natural experiments for investigating the relationship between environmental heterogeneity and species diversity. A review of the global altitudinal distribution of reptiles identified a diverse range of patterns driven by climate and taxonomy. No Australian examples were included in this analysis. We addressed this gap by surveying the reptile assemblage along an altitude gradient from upland rainforest (~1000 m) through to open savanna woodlands (~350 m) in north-eastern Australia. Reptiles were sampled on four separate occasions between May 2006 and November 2007.

The operative temperatures and air temperatures were sampled using data-loggers in the field from 2016 to 2018.

Abstract Lifespan is one of the main components of life history. Shorter lifespans can be expected in marginal habitats. However, in the case of ectotherms, lifespan typically increases with altitude, even though temperature—one of the main factors to determine ectotherms’ life history—declines with elevation. This pattern can be explained by the fact that a shorter activity time favors survival.

As a result, only very few reptile taxa are able to survive above 5,000 m elevation and herpetological observations from these altitudes are exceedingly rare. We report here an exceptional observation of a lizard population (Liolaemus aff. tacnae; Reptilia, Squamata) from the high Andes of Peru. During an ascent of Chachani mountain (6,054 m, 16°11'S, 71°32'W), we observed and documented p

Abstract:

Anan’s rock agama (Laudakia sacra) is a lizard species endemic to the harsh high-altitude environment of the Qinghai–Tibet Plateau, a region characterized by low oxygen tension and high ultraviolet (UV) radiation. To better understand the genetic mechanisms underlying highland adaptation of ectotherms, we assembled a 1.80-Gb L. sacra genome, which contained 284 contigs with an N50 of 20.19 Mb and a BUSCO score of 93.54%. Comparative genomic analysis indicated that mutations in certain genes, including HIF1A, TIE2, and NFAT family members and genes in the respiratory chain, may be common adapta

Abstract:

AbstractField body temperatures (Tbs) were studied in Mabuya striata punctatissima, a high altitude lizard from central Africa. Body temperatures were recorded in the middle of the day when the sun was shining brightly (high activity) and in other weather conditions (low activity). There was a significant correlation between Tb and air temperature (Ta) under both of these conditions, although the slope of the regression was higher in the former. The slope was negative for high activity times during the rainy season. In general, Tbs were higher during high activity than low activity. There were

Abstract We report the first study of diet composition of a Pyrenean lizard of the genus Iberolacerta, the Aurelio's lizard, I. aurelioi, living in an alpine rocky slope at 2300 m of altitude in Andorra. Diet composition was studied during two years from 289 faecal pellets containing 966 prey items. Number of prey per pellet shows annual, seasonal and sexual differences. Diet of the species is poorly diverse, mainly dominated by insects, but we find clear evidences of opportunistic cannibalism based on the presence of toes and scales in feces. In addition, we detected minor sexual, annual and

Abstract:

In this paper, we present data on the female reproductive traits of the Horvath?s rock lizard from Slovenia. The clutch, egg and hatchling characteristics were investigated based on clutches laid in laboratory conditions by pregnant females collected from a natural population. A female lays one clutch of eggs annually with an average number of three (range 1-5) eggs. We found a significant positive correlation between female size and egg width and volume. The mean egg length and volume in a clutch decreased significantly with clutch size independently of female size. The incubation period aver
