Abstract

Body size variation can have important evolutionary, physiological, functional, and ecological consequences. Body mass is a widely used size measure across different taxonomic groups, but it combines skeletal size with nutritional and reproductive status. In bats, forearm length is commonly used as a measure of skeletal size. However, body mass and forearm length are poorly correlated within species. This suggests that the two size variables are measuring different biological attributes. Here, we tested this hypothesis by evaluating the association between body mass, forearm length, and fitness components (survival and reproduction), derived from mark-recapture models, as well as their trends over a nine-year period in a population of short-tailed bats (Carollia perspicillata). Results showed a direct relationship between body mass, survival, and reproduction, and an inverse relationship between forearm length, survival, and reproduction. Different temporal trends in the size variables were observed according to sex and age. Males showed a trend of increasing average mass over the years. In adults, average forearm length decreased over the years, whereas juveniles showed an increasing trend. Our results showed that body mass and forearm length have distinct evolutionary dynamics and proximal mechanisms of change. Forearm length is a measure of wing size and should not be used as a proxy for body size in intraspecific studies.

并非所有的体型测量方法都是一样的:不同的体型代用指标并不能等同于蝙蝠 Carollia perspicillata 的体能预测指标
摘要 体型变化会对进化、生理、功能和生态产生重要影响。体重是不同分类群中广泛使用的体型测量方法,但它将骨骼大小与营养和繁殖状况结合在一起。在蝙蝠中,前臂长度通常被用来衡量骨骼大小。然而,体重和前臂长度在物种内的相关性很差。这表明这两个体型变量测量的是不同的生物属性。在这里,我们通过评估短尾蝠(Carollia perspicillata)种群的体重、前臂长度和体能成分(生存和繁殖)之间的关联及其在九年期间的变化趋势来验证这一假设。结果表明,体重、存活率和繁殖率之间存在直接关系,而前臂长度、存活率和繁殖率之间存在反向关系。根据性别和年龄的不同,体型变量的时间趋势也不同。雄性的平均体重呈逐年增加的趋势。成体的平均前臂长度逐年下降,而幼体则呈上升趋势。我们的研究结果表明,体重和前臂长度具有不同的进化动态和近似变化机制。前臂长度是衡量翅膀大小的一个指标,在种内研究中不应被用作身体大小的替代指标。

期刊介绍: Journal of Mammalian Evolution is a multidisciplinary forum devoted to studies on the comparative morphology, molecular biology, paleobiology, genetics, developmental and reproductive biology, biogeography, systematics, ethology and ecology, and population dynamics of mammals and the ways that these diverse data can be analyzed for the reconstruction of mammalian evolution. The journal publishes high-quality peer-reviewed original articles and reviews derived from both laboratory and field studies. The journal serves as an international forum to facilitate communication among researchers in the multiple fields that contribute to our understanding of mammalian evolutionary biology.
