Juvenile male CZACC 4.5846 (52.2 mm SVL) from Santa Martina, tentatively assigned to Anolis chamaeleonides. The inset above shows details of the scale row between supralabials and infraoculars (arrow, also the scale row in was outlined to increase legibility), which is a diagnostic character for this species. The inset below shows details of the head of a juvenile male A. guamuhaya of comparable size (57 mm SVL) from the southwestern slope of Pico San Juan, notice the supralabials in contact with the infraoculars.

New localities and distribution models inform the conservation status of the endangered lizard Anolis guamuhaya (Squamata: Dactyloidae) from central Cuba. Anolis guamuhaya is known from seven localities restricted to the Guamuhaya Massif in central Cuba and is always associated with mountane ecosystems above 300 m a.s.l. Previous evaluations of the...

... found one juvenile specimen at Santa Martina (CZACC 4.5846) that we tentatively assigned to A. chamaeleonides (because it had a scale row between the supralabials and infraoculars; Garrido et al. 1991), but its small size made it difficult to identify unambiguously (Figure 8; Appendix I). Thus, a second probable point of contact between A. guamuhaya and A. chamaeleonides might be Santa Martina. ...
Context 2
... a second probable point of contact between A. guamuhaya and A. chamaeleonides might be Santa Martina. This seems plausible because the latter species is known to occur in similar ecological conditions about 20 km northwestward, near Juraguá, on the western side of Cienfuegos Bay (Figure 8; Garrido 1980, Rodríguez et al. 2013). Anolis chamaeleonides is widespread in Cuba ( Rodríguez et al. 2013), from sea level to above 1000 m ( Rodríguez et al. 2010), which suggests that it is more generalist than A. guamuhaya. ...

Climate is the dominant control factor on the spatial distribution of organisms on a global scale and global warming is predicted to become a major cause of species extinctions. In our study ecological niche modeling (ENM) was used to estimate the effect of projected future climate changes on the pantropical orchid Polystacha concreta as well as to...
Based on a phylogeographic and niche model analyses of the Narrow-billed Woodcreeper (Lepidocolaptes angustirostris), we evaluated the predictions of two diversification hypotheses related to the dry diagonal of South America: (I) isolation by distance (IBD) and (II) landscape heterogeneity. We also investigated the influence of the Pleistocene cli...
The short-tailed chinchilla (Chinchilla chinchilla) is a species classified as endangered throughout its distribution and for which neither a conservation nor management plan exists. Ecological niche models (ENMs) allow detection of potential areas of occurrence for species that are rare and/or of conservation interest. Here, we built and evaluated...
Yam species (Dioscorea spp.) constitute important staple foods for local communities in Sub-Saharan in Africa. Among yam species, Dioscorea dumetorum (Kunth) Pax, commonly consumed, has been reported to be among the most nutritious and well-appreciated local resource although it remains neglected and underutilized species in Benin. Here, we combine...

... In sharp contrast with most protected areas of Cuba, the herpetofauna of Lomas de Banao Ecological Reserve has received considerable attention (Garrido et al. 1991;Estrada 1994;Rodríguez-Cabrera 2018;Rodríguez-Cabrera et al. 2020a, 2020b, 2020cTorres and Rodríguez-Cabrera 2020). The fact that A. isolepis was not previously documented for this area reinforces the hypothesis that this species has very secretive habits and that it can go undetected even in relatively well-studied areas. ...
The Dwarf Green Anole, Anolis isolepis, has been regarded as one of the rarest anoles in Cuba. Nonetheless, it has a relatively wide distribution and, although most records are restricted to eastern Cuba, some additional records for the central region of the island exist and, interestingly, only a few records of this species exist between the eastern and central populations. The latter might be due to a combination of extensive deforestation across those provinces and a lack of surveys. In central Cuba, it has been recorded from a few localities on the western side of the Guamuhaya Massif, the so-called Trinidad Range. Herein we report A. isolepis from Lomas de Banao Ecological Reserve in the westernmost Guamuhaya Massif.
... It uses as baseline climatic information data from 1960 to 1990 taken from weather stations and estimate values to areas not covered between stations. Climatic variables were selected based on the results of a pilot modelling study in combination with natural history data (Angetter et al., 2011;Brito et al., 2011;Rodríguez-Cabrera et al., 2020). The pilot model was made to identify the group of variables that could best explain the patterns of distribution of the Cuban species. ...
... Anthropogenic habitat loss and/or modification, due to agriculture, logging, urban development and mining, is considered a very important threat to reptile biodiversity (Doherty et al., 2020;Cordier et al., 2021;Cox et al., 2022). However, climate change needs to be considered as another factor that poses a great risk to tropical reptiles (Huey et al., 2009;Sinervo et al., 2010Sinervo et al., , 2017Pontes-da-Silva et al., 2018;Diele-Viegas et al., 2019;Thonis and Lister, 2019;Rodríguez-Cabrera et al., 2020;Srinivasulu et al., 2021, this study). Nevertheless, predictions with low-resolution environmental data at a macro-scale rather than using microclimate conditions may overestimate the susceptibility of these species to shifting climates (Logan et al., 2013). ...
Geographical ranges and physiological tolerances of species are correlated, and it can be expected that widespread species encounter higher climatic variation across their distributions than restricted species. Widespread species should consequently be more tolerant to extreme or variable weather conditions, and may have the ability to better conserve their current geographical ranges under future climate change scenarios. We tested this hypothesis by studying the relationship between the climatic variation experienced by restricted and widespread Anolis lizards from different ecomorphs and regions of Cuba and the distributional shifts induced by climate change. We selected seven bioclimatic variables from WorldClim to characterize the realized climatic niche of 12 Cuban anoles, where the coefficients of variation of each variable were taken as a measure of climatic variation. We used niche modeling to predict changes in suitable habitats under future climatic scenarios. We found that species from Eastern Cuba occupy areas with the highest climatic variation, likely related to the topography of the region. Crown giant anoles experienced habitats with lower climatic variation in comparison with species from other ecomorphs, which together with their tree canopy habitat and large body size may represent a disadvantage to face changing climates. All species will experience a severe decrease in their habitat suitability, with the Western species being predicted to lose a higher proportion of suitable habitat. Combining niche modeling with physiological data would better predict the effects of climate change on Cuban lizards and might allow taking management actions for species and habitats to mitigate the possible negative impacts of this phenomenon.
