Effects of Natural Environmental Conditions on the Ovarian Histometric Dynamics of Five Striped Squirrels (Funambulus pennanti)

The present study was designed to determine the morphological and histological variations in the female palm squirrel's reproductive organs which inhabit croplands of central Punjab. 16 specimens were collected from 3 different locations of Faisalabad district during different months in order t...
