愛德華茲等人。[Nature 449,1044-1048(2007)]回顧了關(guān)于游蕩信天翁飛行持續(xù)時(shí)間頻率分布的冪律的著名研究,并得出結(jié)論,沒有一個(gè)L\'evy過程能夠以更高的分辨率模擬最近的觀測(cè)結(jié)果。在這里,我們表明這種重新分析遭受了概念上的誤解,新的信天翁數(shù)據(jù)仍然與生物飛行一致。

英文摘要:
Edwards et al. [Nature 449, 1044-1048 (2007)] revisited well-known studies reporting power-laws in the frequency distribution of flight duration of wandering albatrosses, and concluded that no L\'evy process could model recent observations with higher resolution. Here we show that this re-analysis suffers from a conceptual misunderstanding, and that the new albatross data remain consistent with a biological L\'evy flight.
