dc.description.abstractThe present study was conducted to estimate the population abundance and dynamics of Pteropus giganteus, its preference in roosting sites, genetic variation and evaluation of pesticide residues at Chatpat Bani (district Pathankot), village Katani Kalan (district Ludhiana) and village Longowal (district Sangrur) during 2019-20. The mean bat population on different tree species was higher at Chatpat Bani than at village Longowal. At Chatpat Bani, mean bat population was maximum during summer (3139.0) whereas maximum during winters (425.0) at Longowal. At Chatpat Bani, per cent bat population roosted on trees was highest on Indian ash tree (79.0%) and lowest on Punjab fig (2.38%) whereas it was highest on safeda (50.88%) and lowest on ber tree (3.37%) at Longowal. At Chatpat Bani, the concentration level of heavy metals was estimated in faecal pellets and among all, Cr (17.35 ppm) was highest while As (0.99 ppm) was lowest, whereas at Katani Kalan, the concentration level of Cr (24.87 ppm) was highest while Cd (0.64 ppm) was lowest and at Longowal, highest concentration levels were recorded in Cr (26.30 ppm) while lowest in Cd (1.72 ppm). In a similar trend, concentration levels of macro- and micro-elements varied in all selected locations. Contamination of pesticide residues in faecal pellets was found negligible as GLC showed values below detectable limits i.e., <0.05 ppm at selected locations. The genetic variability of P. giganteus was studied in Pathankot and Ludhiana using faecal pellet samples. The full-length nucleotide sequences of bat mtCOI gene are 702 bp in both samples.en_US
