Mate choice or intersexual selection is an evolutionary process in which generally the male mate by a female chooser is dependent on the attractiveness of the phenotypic traits and sexual selection is a mode of natural selection where members of one sex choose mates of other sex to mate with intersexual selection, and compete with members of the same sex for access to members of the opposite sex. Reproductive success is attained by either preferring attractive mates or healthy partners. The phenotypic traits selected by male combat are called secondary sexual characteristics (horns, antlers, etc.) which Darwin described as weapons were selected for this study. We address the effect of female group size on male roosting behaviour in the short-nosed fruit bat C. sphinx. We predicted that the time spent by harem males on social grooming by reciprocal licking, tent maintenance, and tent guarding activities would increase with increased female group size. Furthermore, we predicted that the foraging time of harem male bats decreases with increased female group size. Precipitated proteins were purified by FPLC and the preliminary analysis of salivary protein was performed by 2-D gel electrophoresis. Still, standardization of 2-D gel electrophoresis has to be done. MHC class II DRB exon 2 PCR optimization was done using the same primers targeting Noctilio albiventris microbat. Even, though C. sphinx is the least concerned species, the count of C. sphinx is reducing drastically due to several factors. Such as hunting, roost destruction both man and nature, and resource availability. So, we must safeguard this species from poachers and other threats. Every organism is essential for healthy growth and balance of nature.
