| contents | (Uploaded by Plazi for the Bat Literature Project) The greater Asiatic yellow house bat (Scotophilus heathii) is one of the commonest and widely distributed bat species in Pakistan. Little is known about the reproductive biology of this bat. Both sexes roost separately except during January to March. The breeding season is however not well defined. This study was designed to investigate different morphological and histological changes in different months of the year in order to determine the actual period when male bats were reproductively active, along with seasonal changes in the spermatogenic activity of this bat. For this purpose, a group of 9 bat species of S. heathii were captured from different areas of Faisalabad in different months of the year. Morphometric measurements of each bat were made by digital Vernier caliper in order to confirm about the exact specie. Tests were taken and their different morphological parameters were taken. Histology of the testes was studied to explore various stages of spermatogenesis using different histological techniques like Fixation, Dehydration, Sectioning, Staining, and preservation. Histomorphometric measurements were also made by image J analysis. All parameter values were taken as Mean±SE. By using one way ANOVA and Fischer LSD the obtained data was analyzed, which showed highly significant values of all parameters, P<0.005. In this study, the morphological parameters and histological parameters were observed, which showed lowest values of all parameters except lumen area, in February and March, which was non spermatogenic period. In September, parameters showed low spermatogenic activity. In November all parameters were at their maximum value, which indicating the peak spermatogenic period for this bat. These results suggest the occurrence of an annual testicular cycle defined by three distinct reproductive periods. |
