Panthers and Forests in South Florida: an Ecological Perspective Ecology and Society

Jane; University of Tennessee; ecomiske@tiem.utk.edu; Bass, Jr., Oron L; Everglades National Park; Sonny_Bass@nps.gov; Gross, Louis J; University of Tennessee; gross@tiem.utk.edu; McBride, Roy T; Livestock Protection Company;; Salinas, Rene; University of Tennessee; salinas@tiem.utk.edu.
The endangered Florida panther (Puma concolor coryi) survives in an area of pronounced habitat diversity in southern Florida, occupying extensive home ranges that encompass a mosaic of habitats. Twenty-one years of daytime monitoring via radiotelemetry have provided substantial but incomplete information about panther ecology, mainly because this method fails to capture movement and habitat use between dusk and dawn, when panthers are most active. Broad characterizations of panther habitat suitability have nonetheless been derived from telemetry-based habitat selection studies, focusing narrowly on forests where daytime resting sites are often located. The resulting forest-centered view of panthers attributed their restricted distribution and absence of...

Toward a Panther-centered View of the Forests of South Florida Ecology and Society
Kerkhoff, Andrew J; University of New Mexico; kerkhoff@unm.edu; Milne, Bruce T; University of New Mexico; bmilne@sevilleta.unm.edu; Maehr, David S; University of Kentucky; dmaehr@pop.uky.edu.
Anthropogenic habitat degradation and loss is the single largest threat to the endangered Florida panther, Puma concolor coryi. Conservation of the subspecies must be undertaken on the scale of the entire landscape. Thus, a view of the forested landscape of South Florida must be developed that is meaningful with reference to the panther. We approach this problem by analyzing the spatial interactions of panthers and forests at multiple scales. We apply tools derived from fractal geometry to the analysis of 12 years of telemetry observations of panthers and remotely sensed forest cover imagery. A fractal characterization extends conventional scale-dependent measures of forest density and relates intuitively to panther ecology. To move toward a...

Shopping Centers as Panther Habitat: Inferring Animal Locations from Models Ecology and Society
Maehr, David S; University of Kentucky; dmaehr@uky.edu; Larkin, Jeffery L; ; jllark0@uky.edu; Cox, John J; ; coyote1701@yahoo.com.
A recent model of Florida panther (Puma concolor coryi) habitat erred in arbitrarily creating buffers around radio locations collected during daylight hours on the assumption that study animals were only at rest during these times. The buffers generated by this method likely cause an overestimation of the amounts and kinds of habitats that are used by the panther. This, and other errors, could lead to the impression that unfragmented forest cover is unimportant to panther conservation, and could encourage inaccurate characterizations of panther habitat. Previous 24-hour monitoring of activity and activity readings made during routine telemetry flights indicate that high levels of activity occur in the early morning hours. Literature on the behavior of the...
