“…Climatic conditions (hot and dry) and human interferences are rapidly intensifying the susceptibility [88]. The presence of fencing has contributed to increased vegetation and biomass at the protected site, with minimal seasonal effects [89].…”

This study aimed to assess the long term effects of anthropogenic, climatic, edaphic, and seasonal variations on present floristic and ecological status of two distinct sites i.e., protected (Biodiversity Park) and unprotected (nearby areas) in the Derawar region of Lesser Cholistan Desert. The study was conducted for four years over a seasonal period of spring 2019 (February-March) to fall 2022 (September to October). For the exploration of maximum diversity at both sites, quadrats of 10 × 10 m were placed randomly. Ten soil, twelve anthropogenic, seven environmental and eight seasonal variables were used to assess their relationship with vegetation of both sites during four years of study. For statistical analysis, data was processed in the SPSS for LSD test and R Studio for Canonical Correspondence Analysis (CCA) and heat map preparation. A total of 84 plant species, belonging to 62 genera and 26 families, were identified in the Derawar region. Herbaceous plants comprised the majority, with 42 species, followed by grasses (22 species), shrubs (12 species), trees (7 species), and one sedge species. The protected site exhibited higher species diversity, with 76 species from 23 families, compared to the unprotected site, which had 49 species from 15 families. Species richness, Simpson index, and Shannon index showed significant declines in diversity from the protected to the unprotected site.

Avoiding dangerously hot body temperatures is important for survival, but animals may perform reproductive behaviors at the expense of behaviors used to cool down (or vice-versa), resulting in a thermoregulation-reproduction trade-off. Although this trade-off has been demonstrated in semi-aquatic animals, it has not been studied in terrestrial ectotherms. This is an important research gap given the importance of survival-reproduction trade-offs in evolutionary ecology and the pace of habitat warming due to vegetation loss and global climate change. We explored this trade-off in territorial males of the lizard Sceloporus ochoterenae, which mates during the hot-dry season in seasonally dry tropical forest. We rst con rmed the existence of a temporal trade-off between performing push-ups (a territorial behavioral display) versus sheltering in the shade (thermoregulatory behavior), then used con rmatory path analysis to explore how it is affected by vegetation cover, microclimate temperature, and the presence of a conspeci c intruder. We found that territories with less vegetation cover had higher microclimate temperatures, where focal males spent more time performing push-ups at the expense of sheltering in the shade. Focal males also spent more time performing push-ups the longer an intruder was present, who was also affected by the environmental variables. Territorial males spent more time in sunny spots when performing push-ups despite the potential for overheating, perhaps because the display is more effective when performed in the open. The potential effects of continued habitat warming on this trade-off vary widely, including intensifying it, driving lizards to change their daily activity rhythms, and chronic overheating.
