Urbanization—The Bad, The Good, And The Very Good, Rebecca Dolan
Urbanization—The Bad, The Good, And The Very Good, Rebecca Dolan
Rebecca W. Dolan
Great strides have been made in studying effects of urbanization on plant life in recent years. However, much remains to be learned about how the urban environment acts as a filter on flora. There is some evidence that environments in cities are so similar that they all select for the same plants or plants with the same suite of characteristics, resulting in biotic homogenization, but the jury is still out. We do know that some cities harbor a thriving and diverse native flora. Dolan will talk about what cities can do to increase the chances for long-term survival of native …

Hypericum Cumulicola Demography In Unoccupied And Occupied Florida Scrub Patches With Different Time-Since-Fire, Pedro Quintana-Ascencio, Rebecca Dolan, Eric Menges

1 Metapopulation models predict that unoccupied, but suitable, patches will exist for species subject to extinction and colonization dynamics. We compared the demographic responses of Hypericum cumulicola, a rare herbaceous species almost entirely restricted to Florida rosemary scrub, when transplanted to occupied or unoccupied patches. 2 Seedlings were transplanted and seeds buried into Florida rosemary scrub patches differing in time since last fire, and in the presence or absence of H. cumulicola. We used a replicated, factorial design to place the transplants and seeds in the field, and monitored their performance for 18 months. 3 Neither time-since-fire nor prior H. …
