The expectation is to highlight effective conservation approaches and propose future research directions that incorporate both ecological and evolutionary perspectives, ultimately contributing to the development of more robust and adaptive conservation programs for reptiles worldwide. 2 The Ecological Framework for Reptile Conservation 2.1 Key ecological concepts relevant to reptile conservation Reptile conservation is deeply intertwined with understanding their ecological roles and interactions within ecosystems. Reptiles, particularly in tropical regions, play significant roles in ecological processes such as gene dispersal, nutrient cycling, and ecosystem engineering. These roles are crucial for maintaining ecosystem functions and biodiversity (De Miranda, 2017). The global distribution of reptiles, which differs significantly from other vertebrate groups, highlights the need for targeted conservation efforts that consider their unique ecological contributions and distribution patterns. 2.2 Habitat requirements and niche specialization Reptiles exhibit a wide range of habitat requirements and niche specializations, which are critical for their survival and conservation. For instance, the suitability of overwintering habitats for reptiles like freshwater turtles and snakes is influenced by ecohydrological and spatial complexities within wetlands. Additionally, the locomotor adaptations of Mesozoic marine reptiles illustrate the diversity of ecological niches occupied by reptiles, emphasizing the importance of habitat-specific conservation strategies (Gutarra et al., 2023). 2.3 Species interactions: predation, competition, and mutualism Species interactions such as predation, competition, and mutualism are vital components of reptile ecology. These interactions can influence various aspects of reptilian life, including sleep patterns, which are shaped by ecological factors like predation risk and competition (Mohanty et al., 2021). Furthermore, the ecological roles of reptiles in tropical ecosystems, such as their involvement in trophic interactions, underscore their importance in maintaining ecological balance. 2.4 Climate change and its impact on reptile ecology Climate change poses significant challenges to reptile ecology and conservation. Changes in climate can alter habitat availability and suitability, particularly in sensitive ecosystems like wetlands, which are crucial for the survival of many reptile species (Markle et al., 2020). Additionally, urban expansion and climate change can impact reptile populations by altering their habitats and ecological interactions, necessitating adaptive conservation strategies (Brum et al., 2022). 3 Evolutionary Perspectives in Reptile Conservation 3.1 Evolutionary adaptation and genetic diversity Evolutionary adaptation and genetic diversity are critical components in the conservation of reptiles, as they underpin the ability of species to survive and thrive in changing environments. Genetic diversity is intimately tied to evolutionary fitness, influencing the demographic stability and resilience of populations (Dewoody et al., 2021). For instance, the study of the Christmas Island blue-tailed skink and Lister’s gecko highlights the importance of maintaining genetic diversity in captive populations to ensure successful reintroductions and long-term survival (Dodge et al., 2023). High genome-wide heterozygosity observed in these species suggests large historical population sizes, which are crucial for maintaining genetic health and adaptability. Moreover, the integration of genomic, physiological, and morphological data can provide insights into local adaptations, such as those observed in the lizard Liolaemus fuscus, which has adapted to the extreme conditions of the Atacama Desert (Araya-Donoso et al., 2021). This study demonstrates how genetic divergence and specific physiological traits, like reduced evaporative water loss, contribute to the species’ survival in harsh environments. Such adaptations are essential for the conservation of reptiles, as they highlight the evolutionary processes that enable species to cope with environmental pressures.
