It has been suggested that the rol genes of Agrobacterium rhizogenes could play an essential role in the activation of secondary metabolite production in plant transformed cultures. This study investigated whether the content of anthraquinone phytoalexins was changed in callus cultures of Rubia cordifolia transgenic for the 35S-rolB and 35S-rolC genes in comparison with a non-transformed callus...

Classifying the diet of ancient animals is important for understanding biological phenomena such as resource partitioning and the evolution of particular environments. Focusing on Bison, Equus, and Mammuthus from three geographical areas of Florida (north, central, and south) during the Rancholabrean, this study uses values of stable carbon isotope composition of tooth enamel carbonate collecte...

The Florida Sand Skink (Plestiodon reynoldsi), the Florida Scrub Lizard (Sceloporus woodi), and the Six-lined Racerunner (Aspidoscelis sexlineata) occur in the threatened and fire-maintained Florida scrub habitat. Fire may have different consequences to local genetic diversity of these species because they each have different microhabitat preference. We collected tissue samples of each species ...

The first collections of Aedes scapularis (Rondani) (Diptera: Culicidae) from the Florida Keys in 70 yr are reported Boca Chica Key and West, Florida, USA. importance this species as a disease vector is briefly discussed.

Florida ranks third among states east of the Mississippi river and 12th nationally in total number of beef cows (Florida Agricultural Statistics Service, 2002 Report). In contrast with other states, that may feed or background many of their weaned calves, more than 75% of Florida's calves are marketed each year. The beef industry in Florida is based primarily on calves that are conceived, born,...
