摘要
Periodical cicadas, Magicicada spp., are a useful model system for understanding the 族群 processes that influence range boundaries. Unlike most insects, these 物種 typically exist at very high densities (occasionally >1000/ m(2)) and have unusually long life-spans (13 or 17 years). They spend most of their lives underground feeding on plant roots. After the underground period, adults emerge from the ground to mate and oviposit over a period of just a few days. Collections of 族群s that are developmentally synchronized across large areas are known as "broods". There are usually sharp boundaries between spatially adjacent broods and regions of brood overlap are generally small. The exact mechanism behind this developmental 同步化 and the sharp boundary between broods remain unknown: previous studies
