The present study was conducted to explore morphometric variations of Pteropus medius (the Indian flying fox) and the roosting trees in Lower Dir, Pakistan. The bats were captured from Morus alba, Morus nigra, Brousonetia papyrifera, Pinus raxburghii, Hevea brasiliensis, Platanus orientalis, Populous nigra, Melia azedarach, Eucalyptus camaldulensis and Grevillea robusta through sling shot and mess net methods. A total of 12 bats were studied for the differential morphological features based on age and sex. Male bats were recorded higher in weight than females. The variations were found in body mass (821.1±34.65gm), circumference of body with wings (25.43±0.39cm), wingspan (112.58±1.90cm), Body length (20.73±0.68cm), Snout length (3.42±0.04cm), Eye length (1.45±0.033cm), Length of ear (3.56±0.05cm), Width of ear (2.46±0.04cm), Length b/w ear (5.51±0.11cm), Circumference of neck (12.23±0.24cm), Circumference of body without wings (18.68±0.31cm), Arm wing length (23.2±1.03cm), Length of thumb (5.43±0.1cm), Length of nail (1.89±0.05cm), Hand wing length (29.1±0.51cm), Maximum width of wing (21.03±0.68cm), Length b/w tip of wing to 5th digit (29.39±0.30cm), Length b/w 5th digit to foot (22.97±1.09cm), Length b/w feet (18.31±0.74cm) and Length of foot claw (4.23±0.05cm). This study was designed for analysis of external morphological variations for P. medius (the Indian flying fox) that may help in identification of these bats and their roosting sites.

本研究旨在探索Pteropus medius (印度飞狐) 和巴基斯坦Lower Dir的栖息树木的形态变化。蝙蝠是通过吊带射击和杂乱网方法从桑树,黑桑树,木瓜,松松,巴西橡胶树,东方悬铃木,人口众多的黑树,油菜,桉树和Grevillea robusta捕获的。总共研究了12只蝙蝠的年龄和性别差异形态特征。记录到雄性蝙蝠的体重高于雌性。体重 (821.1 ± 34.65gm),有翅膀的身体周长 (25.43 ± 0.39厘米),翼展 (112.58 ± 1.90厘米),体长 (20.73 ± 0.68厘米),鼻子长 (3.42 ± 0.04厘米),眼长 (1.45 ± 0.033厘米),耳长 (3.56 ± 0.05厘米),耳宽 (2.46 ± 0.04厘米),耳长b/w (5.51 ± 0.11厘米),颈围 (12.23 ± 0.24厘米),无翼体围 (18.68 ± 0.31厘米),臂翼长 (23.2 ± 1.03厘米),拇指长度 (5.43 ± 0.1厘米),指甲长度 (1.89 ± 0.05厘米),手翼长度 (29.1 ± 0.51厘米),翼最大宽度 (21.03 ± 0.68厘米),翼尖到第5位长度b/w (29.39 ± 0.30厘米),到脚的长度b/w第5位 (22.97 ± 1.09厘米),脚的长度b/w (18.31 ± 0.74厘米) 和脚爪的长度 (4.23 ± 0.05厘米)。这项研究旨在分析P. medius (印度飞狐) 的外部形态变化,这可能有助于识别这些蝙蝠及其栖息地点。
