| Abstract | Considerable attention has been devoted to the effects of people on birds and mammals, usually in wilderness areas. In contrast, human disturbance of reptiles has largely been ignored. Many reptiles, such as snakes, are hard to conserve because they are difficult to locate and protect. The young are especially vulnerable to predators when they first hatch and must emerge from nest sites. In this paper, the response of pine snake (Pituophis melanoleucus) hatchlings to the presence and handling by people was observed in the laboratory and in the field. Pine snakes lay their eggs in underground burrows in open sandy pine barrens, and the hatchlings push their way to the surface to emerge. Hatchlings that were visually-disturbed or touched as they emerged returned immediately to their tunnels and nests, and required more time to re-emerge than did their siblings that were not visually-disturbed or touched during their initial disturbance. In nature, undisturbed pine snakes showed similar re-emergence times to those from the laboratory, and disturbed snakes required longer to re-emerge. These data suggest that in nature even the presence of people in nesting areas of pine snakes would lengthen the time the young are in burrows, exposing them to additional threats from predators. This suggests that parks or nature reserves with vulnerable snake populations should restrict human disturbance during the period when young snakes are emerging from their nests. Field observations indicate that a set-back distance of more than 12 m from known nesting areas is essential to protect emerging hatchlings. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
