Abstract

ABSTRACT The Eastern American Toad, Anaxyrus americanus americanus (Holbrook, 1836) is an ubiquitous and geographically wide-ranging subspecies of eastern North America. As such, it also varies geographically in several of its life history traits. A statewide examination of its gonadal cycles and body size-age relationships in Pennsylvania revealed a conformity to contemporary latitudinal patterns associated with these life history traits. Likewise, these very responses to spatial differences in climate, we proffer, predispose the Eastern American Toad to climate-change related shifts in timing of reproduction in Pennsylvania. Such a change, depending upon the reproductive response to climate change by Fowler's Toad, Anaxyrus fowleri (Hinckley, 1882), could result in an increased likelihood of hybridization, a phenomenon with significant evolutionary implications.

美国东部蟾蜍,Anaxyrus americanus americanus (Holbrook, 1836)的性腺周期和性成熟发育
美洲东部蟾蜍,Anaxyrus americanus americanus (Holbrook, 1836)是北美东部普遍存在且地理分布广泛的亚种。因此,它的一些生活史特征在地理上也是不同的。在宾夕法尼亚州全州范围内对其性腺周期和体型与年龄关系的研究显示,与这些生活史特征相关的当代纬度模式是一致的。同样,我们认为,正是这些对气候空间差异的反应,使东美洲蟾蜍在宾夕法尼亚州的繁殖时间容易受到气候变化相关的变化的影响。这种变化,取决于福勒氏蟾蜍(Anaxyrus fowleri, Hinckley, 1882)对气候变化的生殖反应,可能导致杂交的可能性增加,这是一种具有重大进化意义的现象。

期刊介绍: Annals of Carnegie Museum is a quarterly journal that publishes peer-reviewed short and medium-length original scientific contributions in organismal biology, earth sciences, and anthropology, in 40 by 52.5 pica format (168 by 220 mm or 6-5/8 by 8-5/8 inches). Subject matter must be relevant to Carnegie Museum of Natural History scientific sections or Powdermill Nature Reserve (PNR), preferably with connection to the Carnegie collection and/or personnel. Carnegie Museum staff and research associates receive publication priority, but others are encouraged to submit papers, especially those manuscripts explicitly based on the Carnegie collection.
