BBC Cicada dual emergence brings chaos to the food chain 3 days ago
By Lucy Sherriff
例の「素数蝉」。稀に同時発生して遺伝子の交流をするが、その他の時は全滅を避けるために違った年数（13か17年か）、幼虫でいる戦略をとるあれ。同時に出ちゃう今年はエライことやかましい。
「When trillions of periodical cicadas emerge in a rare double event, they provide a disruptive feast for other species.
This April, trillions of periodical cicadas began their descent on the midwest and southeast of the United States, causing so much noise that local residents called the police to complain.」
が、警察に言って何をどうする気なんだ君たちは。
が、ともかく。猛烈な数の蝉成虫が乱舞する分、騒音に限らず、その他の影響があるというわけだ。そりゃそうだ。
「The emergence would not directly impact the human food system, Soltis adds, but unusually high levels of cicadas aren't good news for all. So scientists are capitalising on 2024's dual emergence to find out more about the insects' ripple effect on other species, both in the animal kingdom and in plants.」
「The insects will provide a lavish banquet for all kinds of wildlife. Birds of all shapes and sizes – sparrows, crows, swallows, to name a few – opportunistically shift their diet to take advantage of this cicada buffet. A study, published in 2023, found the emergence of periodical cicadas changes the diets of entire bird communities.」
「Scientists have found that wild turkeys, for example, will capitalise on the bounty, leading to a wild turkey boom. Shrews, a small mole-like mammal, also dine on cicadas, as do bats, spiders, wasps, and even snakes, says Lill.」
そりゃ大型で捕えやすいんだろう。しかも美味いんだろう。鳥や蝙蝠や…がそのほかの昆虫ではなく蝉を選ぶことで、そのほか害虫の類を取ってくれなくなっちゃう。
「Rising temperatures will lead to periodical cicada emergences starting earlier in the year, experts believe, as well as an increase in unexpected, "oddly-timed" emergences.」
…気候変動のおかげでこの素数蝉の登場時期も微妙に早くなったらしく。リップル・エフェクトがどんなもんか、何かあることは分かっても測りがたい、といったわけかねえ。
