Ecological Section Hoch, Peter [1], Miller-Struttmann, Nicole [2], Krakos, Kyra [3]. Differential phenological change among communities. Analysis of the changes that have occurred in plant phenology at a reserve in eastern Missouri over a 70-year span (1937-1942 to 2009-2012) shows strikingly different responses to climate change among different communities at the reserve. Early-blooming species, concentrated in forests, initiate bloom about 7-10 days earlier but have a similar bloom duration over this 70-year span. Late-blooming species, found primarily on glades (specialized hot, dry habitats) and grasslands, also initiate bloom earlier but have significantly longer bloom duration. These results may reflect the different phylogenetic and/or biogeographic affinities of the communities. Analyses have been initiated to determine how these changes relate to the behavior, affinities, and community structure of the pollinating insects, as well as to the reproductive success of the plants themselves.
