摘要
岛屿上的体型进化得到了广泛的研究和激烈的争论。巨人症和侏儒症被认为是在强烈的自然选择下进化而来的,尤其是在偏远的小岛上。我们报告了一个奇怪的侏儒蜥蜴和巨型蜥蜴在同一个小而偏远的岛屿上共存的现象:最大的Podarcis erhardii (Lacertidae)和最小的Mediodactylus kotschyi sensu lato;壁虎科-爱琴海中最常见的两种岛屿爬行动物。Plakida的壁虎有一种奇特的摇尾行为,这是该属首次记录。我们怀疑埃尔哈地弓形虫进化出巨大的体型是为了捕食壁虎,而壁虎进化出独特的摇尾行为作为一种防御机制。
The Island of Extremes: Giants and Dwarfs on a Small Remote Island
Body size evolution on islands is widely studied and hotly debated. Gigantism and dwarfism are thought to evolve under strong natural selection, especially on small remote islands. We report a curious co-occurrence of both dwarf and giant lizards on the same small, remote island (Plakida): the largest Podarcis erhardii (Lacertidae) and smallest Mediodactylus kotschyi sensu lato; Gekkonidae — the two commonest insular reptiles in the Aegean Sea. The geckos of Plakida have a peculiar tail-waving behavior, documented here for the first time in this genus. We suspect that P. erhardii evolved large size to consume geckos and the geckos evolved a unique tail-waving behavior as a defensive mechanism.
