“…Amphibians clearly demonstrate a range of species, regional, and temporal phenological responses to climate change (e.g., Muths et al, 2017;Okamiya et al, 2021). (Scheffers et al, 2013;, particularly for subterranean environments (Lara-Reséndiz et al, 2021;Moore et al, 2018). Fossorial ectotherms and amphibians in particular may be at elevated risk as their thermal microhabitat warms.…”

Global climate change is unequivocal, and rates of observed and predicted temperature increases are greater at higher latitudes (Intergovernmental Panel on Climate Change, 2014). High-and mid-latitude regions have experienced rapid environmental change over the past half-century, including increases in mean air and surface temperature, extreme high temperature events, decreases in the number of frost-free days, and decreases in ice cover (Bartolai et al., 2015;Cohen et al., 2014). The short post-glacial history of the Northern hemisphere mid-latitudes, combined with regional geology, climate, and varied habitat types, makes this region the

“…Within vertebrate ectotherms, lizards show behavioral adaptations in their thermoregulation strategies that may either amplify or mitigate the impacts of global warming on their survival (Diele‐Viegas et al, 2018; Jara et al, 2019; Lara‐Reséndiz et al, 2021; Meiri et al, 2013; Piantoni et al, 2016; Sinervo et al, 2010). Specifically, behavioral thermoregulation in lizards is manifest in a continuum of behavioral adaptations that ranges between two very disparate strategies: active thermoregulation and thermoconformity (Huey & Slatkin, 1976; Pianka & Vitt, 2003).…”

“…Understanding the strategies behind the movement ecology of any animal is challenging anyway (Nathan et al, 2008) but is particularly so in lizards, where multiple abiotic movement elicitors such as irradiation, temperature, surface water, and humidity play an important role (Cabezas‐Cartes et al, 2019; DeNardo et al, 2003; Diele‐Viegas et al, 2018; Lara‐Reséndiz et al, 2021; Pianka & Vitt, 2003) above and beyond other biological movement elicitors such as predation and foraging (Du et al, 2000; Sannolo et al, 2019).…”

Temperature and barometric pressure affect the activity intensity and movement of an endangered thermoconforming lizard

Global warming is expected to affect movement-related thermoregulation in ectotherms, but the likely effects on thermoconforming lizards, which spend little energy in thermoregulation behavior, are unclear. We used the Guatemalan beaded lizard (Heloderma charlesbogerti) as a model thermoconforming species to investigate the effects of ambient temperature and barometric pressure (a cue for rain in the study area) on activity intensity and the structure of movement paths. We tracked 12 individuals over a total of 148 animal days during the wet season of 2019 using Global Positioning System tags and triaxial accelerometry. We found a clear positive effect of ambient temperature on activity (using vectorial dynamic body acceleration [VeDBA]) and step length of lizard movements. The movement also became more directional (longer step lengths and smaller turning angles) with increasing ambient temperatures. There was a small negative effect of barometric pressure on VeDBA. We propose that our patterns are indicative of internal state changes in the animals, as they move from a state of hunger, eliciting foraging, which is enhanced by lower temperatures and rainfall to a thermally stressed state, which initiates shelter-seeking. Our findings highlight the sensitivity of this species to temperature change, show that not all thermoconforming lizards are thermal generalists, and indicate that predicted regional increases in temperature and reduction in rainfall are likely to negatively impact this species by reducing the width of their operational thermal window.

“…Considering that the lowest elevation of Cucapá is essentially at sea level, future studies could consider climate change predictions in order to evaluate the persistence of species under future scenarios (e.g. with reptiles, see Lara-Reséndiz et al 2020 ; Pérez-Delgadillo et al 2021 ).…”

Knowledge about the biodiversity of Baja California has been obtained mainly from natural protected areas (NPAs), while some unprotected natural areas have been poorly studied. The Sierra Cucapá in the northeast of the peninsula is one example. The objectives of this study are 1) to integrate existing knowledge of bird, mammal, and reptile diversity in Cucapá from public databases, citizen science platforms, and information generated from fieldwork, 2) to identify the spatial distribution of records in the study area, 3) to compare the composition of vertebrate species of Cucapá with that of NPAs of northern part of the peninsula, and 4) to assess the biological conservation value of Cucapá. We obtained records of 150 species of native vertebrates (102 birds, 34 mammals, and 14 reptiles) of which 10 species of birds, four mammals, and seven reptiles are included in a risk extinction category. The different sources of information contributed in a complementary way to the species inventories. Large areas in western and northern Cucapá lack records. The total difference in species composition between Cucapá and nearby NPAs ranged between 58 and 69% for birds, 61 and 79% for mammals, and 69 and 87% for reptiles. The species richness of Cucapá, its particular species composition, the presence of species in risk extinction categories, and the number and size of unexplored areas indicate that this area represents an opportunity for biological conservation in the northern part of the Peninsula. This work provides compelling data for the protection of Cucapá.
