此外,物种分化还包括边缘物种分化(peripatric speciation),小种群与隔离大种群一段时间,期间基因发生剧烈变化,再次相遇时无法与大种群中的个体互相交配了,和临域物种分化(parapatric speciation),两个相邻的种群,经过隔离,相邻的个体间能够互相交配,然而两个种群最极端的个体间已经无法交配,此概念了解即可。 AP考试常见套...

Testosterone has received particular interest in evolutionary biology because of its role in mediating trade-offs between reproductive allocation and self-preservation via physiological effects such as lower investment in immune defense (Muehlenbein and Bribiescas2005) and between mating and parental effort...
5Altmetric Metrics Abstract Species density is higher in the tropics (low latitude) than in temperate regions (high latitude) resulting in a latitudinal biodiversity gradient (LBG). The LBG must be generated by differential rates of speciation and/or extinction and/or immigration among regions, but...
