We investigated the relationship between a body mass index and tooth wear in the black flying-fox (Pteropus alecto Gould) to provide guidance on management of edentulous individuals by wildlife carers and veterinarians.
Flying-foxes brought into care because of injury were weighed, their forearms measured and the state of their teeth evaluated. Measurements were analysed by Chi-square, ANOVA, t-tests and regression to identify any relationship between the body mass index and the condition of canine and molar teeth, as well as in relation to sex and season.
There was no statistically significant relationship between a bat's dentition state and the body mass index being used.
In Townsville, the black flying-fox appears to experience a rapid decline in dental condition over time. Despite this, there is little indication that loss of teeth results in a decline in body condition. We attribute this to the dominance of floral foods in the bats' diet in Townsville and a lesser importance of hard fruit that requires intact dentition for consumption. Edentulousness on its own is not sufficient reason to euthanase black flying-foxes in either Townsville or similar relatively dry localities where blossom dominates the flying-fox diet.
我们研究了黑狐蝠（Pteropus alecto Gould）的体重指数与牙齿磨损之间的关系，以便为野生动物护理人员和兽医管理无牙个体提供指导。
对因受伤而接受护理的狐蝠进行称重、测量前臂，并评估其牙齿状况。通过卡方检验、方差分析、t检验和回归分析测量数据，以确定体重指数与犬齿和臼齿状况之间的关系，以及与性别和季节的关系。
蝙蝠的牙列状态与所使用的体重指数之间没有统计学上的显著关系。
在汤斯维尔，黑狐蝠的牙齿状况似乎会随着时间的推移而迅速下降。尽管如此，几乎没有迹象表明牙齿脱落会导致身体状况下降。我们将此归因于汤斯维尔狐蝠饮食中花卉食物占主导地位，以及需要完整牙列才能食用的硬果重要性较低。在汤斯维尔或类似开花植物在狐蝠饮食中占主导地位的相对干燥地区，仅有无牙这一情况并不足以成为对黑狐蝠实施安乐死的充分理由。
