요약 | While 20th century atmospheric nitrogen (N) deposition has been strongly linked to changes in diatom assemblages in high-elevation lakes, contemporaneous changes in other algae suggest additional causes. Using proxies preserved in lake sediments, we explored the origin and magnitude of changes in an alpine and subalpine lake from the end of the Little Ice Age in the 19th century to ca. 2010. We found dramatic changes in algal community structure. Diatom analyses revealed a pronounced shift from majority benthic to planktonic diatoms ca. 1950, coincident with the rise of atmospheric N deposition. Pigments representing benthic green algae have increased 200-300% since ca. 1950 |
