开普地区的繁殖:墨西哥下加利福尼亚地区的鞭尾蜘蛛(鳞目:虎蛛科)

Stephen R.Goldberg1*和Clark R.Mahrdt2希捷学院生物系，加利福尼亚州惠蒂尔90608 2圣地亚哥自然历史博物馆爬虫学系1788 El Prado，加利福尼亚州圣地亚哥92101*通讯作者；电子邮件：sgoldberg@whittier.edu––––-–––--–––—–––——–––西鞭尾虎Aspidoscelis tigris目前被认为是一种多型物种，在墨西哥下加利福尼亚州包括九个亚种（Grismer 2002）。地方性的开普省虎斑病（Aspidoscelis tigris maximus）发生在南下加利福尼亚开普省干旱的热带地区。Asplund（1967）先前报道了在开普省夏季降雨季节的8月份，A.t.maximus（如Cnemidophorus maximus Cope，1864）的繁殖。本研究的目的是利用博物馆标本中性腺物质的组织学检查，提供关于墨西哥南下加利福尼亚州开普地区虎繁殖周期的额外信息，这种方法通常用于避免从种群中移除额外的标本。提供了雄性和雌性繁殖的最小尺寸。
