The continuity of their habitats is crucial for their survival and reproduction. This review examines how habitat fragmentation affects the distribution, genetic diversity, and behavioral patterns of reptiles, as well as the direct and indirect impacts of these environmental changes on their population dynamics. The focus is on analyzing the geographical distribution and ecological roles of reptiles and how they adapt to the challenges brought about by habitat fragmentation. The aim is to propose effective conservation strategies to mitigate the adverse effects of habitat fragmentation on reptiles and to recommend directions for future research and policy development. Keywords Habitat fragmentation; Reptiles; Genetic diversity; Conservation strategies; Behavioral adaptation 1 Introduction Habitat fragmentation, the process by which large, continuous habitats are divided into smaller, isolated patches, is a significant driver of biodiversity loss and ecosystem degradation worldwide. This phenomenon is primarily driven by human activities such as urbanization, agriculture, and deforestation, which disrupt the continuity of natural landscapes and create isolated habitat remnants (Haddad et al., 2015; Miller-Rushing et al., 2019). The effects of habitat fragmentation are profound, leading to reduced species richness, altered community structures, and impaired ecosystem functions. Fragmentation not only reduces the total habitat area but also increases edge effects, which further degrade the quality of the remaining habitat patches (Aguilar et al., 2019). These changes can have cascading effects on biodiversity, as smaller and more isolated patches support fewer species and smaller populations, increasing the risk of local extinctions. Reptiles, with their specific habitat requirements and limited dispersal abilities, are particularly vulnerable to the impacts of habitat fragmentation. Fragmentation can lead to reduced genetic diversity, lower reproductive success, and increased mortality rates in reptile populations (Delaney et al., 2021). Urbanization, a major contributor to habitat fragmentation, has been shown to significantly affect reptile diversity and abundance, with smaller patches often unable to support viable populations of certain species. Understanding the specific impacts of habitat fragmentation on reptiles is crucial for developing effective conservation strategies, as these species play important roles in ecosystem functioning, such as pest control and nutrient cycling. This study is to examine the extent and nature of environmental fragmentation and its specific impacts on reptile biodiversity, assess the effectiveness of different conservation strategies, such as habitat restoration and the establishment of wildlife corridors, in mitigating the negative impacts of fragmentation, and identify key research gaps and future directions for habitat fragmentation and reptile conservation research, aiming to provide a comprehensive understanding of the challenges that habitat fragmentation poses to reptilian populations and to inform conservation efforts to conserve these important components of biodiversity.
