Brood XIX
Brood XIX (also known as The Great Southern Brood) is the largest (most widely distributed) brood of 13-year periodical cicadas, last seen in 2011 across a wide stretch of the southeastern United States. Periodical cicadas (''Magicicada spp.'') are often referred to as "17-year locusts" because most of the known distinct broods have a 17-year life cycle. Brood XIX is one of only three surviving broods with a 13-year cycle. It is also notable because it includes four different 13-year species, one of which was discovered in Brood XIX in 1998 by scientists listening to cicada songs. Position among other broods of cicadas Every 13 years, Brood XIX tunnels ''en masse'' to the surface of the ground, mates, lays eggs, and then dies off in several weeks. In 1907, entomologist C. L. Marlatt postulated the existence of 30 different broods of periodical cicadas: 17 distinct broods with a 17-year life cycle, to which he assigned Roman numerals I through XVII (with emerging years 1893 th ...

Cicadas
The cicadas () are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, the Tettigarctidae, with two species in Australia, and the Cicadidae, with more than 3,000 species described from around the world; many species remain undescribed. Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings. They have an exceptionally loud song, produced in most species by the rapid buckling and unbuckling of drumlike tymbals. The earliest known fossil Cicadomorpha appeared in the Upper Permian period; extant species occur all around the world in temperate to tropical climates. They typically live in trees, feeding on watery sap from xylem tissue, and laying their eggs in a slit in the bark. Most cicadas are cryptic. The vast majority of species are active during the day as adults, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brood II
Brood II is one of 15 separate broods of ''Magicicada'' (periodical cicadas) that appear regularly throughout the northeastern United States. Every 17 years, Brood II tunnels ''en masse'' to the surface of the ground, mates, lays eggs, and then dies off over the span of several weeks. Although entomologist C. L. Marlatt published an account in 1907 in which he argued for the existence of 30 broods, over the years a number have been consolidated and only 15 are recognized today as being distinct. Brood II is among the 12 different broods with 17-year cycles. History In 1775, Thomas Jefferson recorded in his Memorandum Books Brood II's 17-year periodicity, writing that an acquaintance remembered "great locust years" in 1724 and 1741, that he and others recalled another such year in 1758 and that the insects had again emerged from the ground at Monticello in 1775. He noted that the females lay their eggs in the small twigs of trees while above ground. Brood II last appeared in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Rothenberg
David Rothenberg (born 1962) is a professor of philosophy and music at the New Jersey Institute of Technology, with a special interest in animal sounds as music. He is also a composer and jazz musician whose books and recordings reflect a longtime interest in understanding other species such as singing insects by making music with them. Life and work Rothenberg graduated from Harvard and took his PhD from Boston University. Looking back at his high school years in the 1970s, Rothenberg told Claudia Dreifus of ''The New York Times'', "I was influenced by saxophonist Paul Winter's ''Common Ground'' album, which had his own compositions with whale and bird sounds mixed in. That got me interested in using music to learn more about the natural world." As an undergraduate at Harvard, Rothenberg created his own major to combine music with communication. He traveled in Europe after graduation, playing jazz clarinet. Listening to the recorded song of a hermit thrush, he heard st ...

Reproductive Character Displacement
Character displacement is the phenomenon where differences among similar species whose species distribution, distributions overlap geographically are accentuated in regions where the species co-occur, but are minimized or lost where the species' distributions do not overlap. This pattern results from evolutionary change driven by biological competition among species for a limited resource (e.g. food). The rationale for character displacement stems from the competitive exclusion principle, also called Georgii Gause, Gause's Law, which contends that to coexist in a stable environment two competing species must differ in their respective ecological niche; without differentiation, one species will eliminate or exclude the other through competition. Character displacement was first explicitly explained by William L. Brown Jr. and E. O. Wilson in 1956: "Two closely related species have overlapping ranges. In the parts of the ranges where one species occurs alone, the populations of that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
