Original title: Season-dependent phenological responses and implications for co-occurring plants and butterflies under climate anomalies and extreme weather events
Plants and butterflies change the timing of events such as flowering and activity as seasons pass. Researchers tracked these changes in an old-growth forest for 17 years and compared responses to unusual climate conditions and extreme weather. Extreme weather improved predictions, especially for butterfly timing, and sometimes shifted timing opposite to climate anomalies. Plants and butterflies often differed in how they shifted, but those differences did not change their timing overlap. Greater overlap was linked with more butterfly diversity, depending on the season.
Imagine planning a picnic with a friend across spring and summer. Sometimes you both arrive earlier than usual, but a sudden storm can make one of you late while the other arrives early. In this paper, the picnic timing stands for seasonal timing in plants and butterflies, and the changing arrival times stand for their different responses to climate conditions and extreme weather.
Plants and butterflies can respond differently to unusual weather, and those differences change with the season. Tracking only average climate or spring events could miss important shifts; the study also links greater timing overlap with higher butterfly diversity, though this link varies by season.
The abstract describes observations from one old-growth forest and reports an association between greater overlap and butterfly diversity, not proof that overlap causes diversity. It does not specify which plant or butterfly species were tracked, the individual metrics used, or how the findings apply to other places.
