A Test Of Food Partitioning Between The Aquatic Larvae Of Two Parapatric Species Of Two-Lined Salamander (Eurycea Bislineata Species Complex) In A Zone Of Sympatric Contact, Carlos D. Camp, S. Michael Owensby, Emily Benfield, Jessica A. Wooten
A Test Of Food Partitioning Between The Aquatic Larvae Of Two Parapatric Species Of Two-Lined Salamander (Eurycea Bislineata Species Complex) In A Zone Of Sympatric Contact, Carlos D. Camp, S. Michael Owensby, Emily Benfield, Jessica A. Wooten
Georgia Journal of Science
Phylogenetically related species with similar ecologies often partition resources when in sympatry. Food is an important factor in the co-occurrence of sympatric salamanders, and food partitioning occurs in a variety of sympatric, similar species. Several members of the Two-lined Salamander (Eurycea bislineata) species complex are largely parapatric but co-exist within a narrow zone of sympatric contact. Because larvae of these salamanders frequently occur in very high densities, we tested the hypothesis that larvae of the Blue Ridge Salamander (E. wilderae) and the Southern Two-lined Salamander (E. cirrigera) partition food in sympatry in northeastern Georgia. …
Preliminary Investigation Into The Use Of Logistic Regression To Predict Parasite Intermediate Hosts. Case Study: Dujardinascaris Waltoni (Nemtatoda: Ascarididae) In The American Alligator (Alligator Mississippiensis), Steven Gabrey, Kelly Franklin, Michael Bodri
Preliminary Investigation Into The Use Of Logistic Regression To Predict Parasite Intermediate Hosts. Case Study: Dujardinascaris Waltoni (Nemtatoda: Ascarididae) In The American Alligator (Alligator Mississippiensis), Steven Gabrey, Kelly Franklin, Michael Bodri
Georgia Journal of Science
We present here a case study that illustrates the potential for the use of logistic regression to facilitate identification of a parasite’s intermediate host. We used a full factorial logistic regression to estimate the probability that adult American alligators (Alligator mississippiensis) were infected with the ascarid nematode Dujardinascaris waltoni given the alligators’ physical characteristics and stomach contents. The strength of association between a fish-based diet and infection predict fish as the intermediate host taxon. Significant but weaker associations with reptile-mammal and reptile-crustacean diets are likely due to the high percentage of alligator remains present in the stomachs examined, …
Food Of Eastern Moles, Scalopus Aquaticus, On Cumberland Island, Georgia, John O. Whitaker Jr., Carol Ruckdeschel
Food Of Eastern Moles, Scalopus Aquaticus, On Cumberland Island, Georgia, John O. Whitaker Jr., Carol Ruckdeschel
Georgia Journal of Science
Earthworms are usually the most heavily eaten food of eastern moles, Scalopus aquaticus, and scarabaeid larvae (grubworms), are also often very important. These were the two most important foods of this species on Cumberland Island, Georgia, making up 55.9% of the food by volume. Other important items were beetle larvae (11.3), ants (9.4), and centipedes (4.1). The purpose of this paper is to present information on the food of Eastern Moles on Cumberland Island, Georgia.
Food Of Bobcats And Coyotes From Cumberland Island, Camden County, Georgia, John O. Whitaker Jr., Carol Ruckdeschel, Angela Chamberlain, Lauren Bakken

Fifty scats of bobcats and 105 scats of coyotes from Cumberland Island, Camden County, Georgia, were examined during this study. Major foods of bobcats were mammals (81.8% volume), followed by birds (13.8%) and vegetation (4.2%), with only 0.2% invertebrates. Major foods of coyotes were plant materials (46.6% volume), mammals (43.8%), and invertebrates (6.0%). This is apparently the first report of coyote foods from Cumberland Island.
