Soil Microbial Community Dynamics In Florida Scrub Ecosystem, Maria Albarracin Jan 2005

Soil Microbial Community Dynamics In Florida Scrub Ecosystem, Maria Albarracin

Electronic Theses and Dissertations

Pyrogenic ecosystems are maintained by fires which vary in frequency, seasonality, and intensity. Florida oak-saw palmetto scrub ecosystem is characterized by fires occurring at intervals of 10-20 years. Diverse factors as private land acquisition and development has created a patchy distribution of scrub ecosystems and also interrupted the natural fire cycle. The effects of fire over plant regeneration and fauna habitat utilization of the scrub have been well characterized in previous research. In the present paper the objective is to characterize the short- and long-term fire effects on the soil microbial community. Fire effects were studied in a chronosequence, comprising …


Site Preparation Methods For Restoration Of Non-Native Pasturelands To Native Upland Habitat, Krisann Joie Kosel Jan 2005

Site Preparation Methods For Restoration Of Non-Native Pasturelands To Native Upland Habitat, Krisann Joie Kosel

Electronic Theses and Dissertations

The flatwoods ecosystem of Florida has been heavily depleted over time but remains one of the most important systems to many threatened and endangered species. Areas that have been converted into non-native pastures may be restored to provide not only this invaluable ecosystem but also restore connectivity of the surrounding ecosystems. The pasture areas on The Disney Wilderness Preserve in central Florida were surveyed, and a conceptual plan for restoration was written in 1996. That same year a pilot study was developed to assess five methods for removing non-native pasture grasses. The treatments studied were single herbicide, single disc, multiple …
