STEYERMARK, A.C.; NELSON, D.E.; PIKOVSKY, A.; GIANG, A.H.; University of St. Thomas; University of St. Thomas; Breck High School; University of St. Thomas: Activity patterns of juvenile snapping turtles and their effects on preferred temperature choice and metabolic rate The existence of daily rhythms in the regulation of many body processes has been well documented […]

CHI*, K.-J.; KAJIURA, S.M.; SUMMERS, A.P.; Duke U.; FAU; UCI: A running nose: Biomechanics of peripheral olfactory organs of the spiny dogfish and hammerhead sharks The mechanics of odor perception in fishes is poorly understood. The nasal rosette is morphologically diverse raising the possibility of variable flow regimes, and in actively swimming sharks we suppose […]

STOCK, D.W.*; TRAPANI, J.; JACKMAN, W.R.; Univ. of Colorado, Boulder: A developmental genetic investigation of dentition reduction in cypriniform fishes Evolutionary reduction of vertebrate dentitions is a frequent phenomenon, while regain of lost teeth is rare. We have used loss of oral teeth in cypriniform fishes as a model to investigate whether this trend is […]

FINKLER, M.S*; GILLEM, A.D.; Indiana Univ. Kokomo: A comparison of stored energy reserves before and after oviposition in female Ambystoma texanum and sympatric Ambystoma jeffersonianum-laterale complex gynogenics We examined interspecific differences in the storage lipid and glycogen contents of female Ambystoma texanum (a bisexual species) and gynogenic hybrid females from the Ambystoma jeffersonianum-laterale complex found […]

RENSEL, M.A.*; ELLIOTT, J.K.; WIMBERGER, P.; University of Puget Sound; University of Puget Sound; University of Puget Sound: Will the introduced mussel Mytilus galloprovincialis outcompete the native mussel M. trossulus in Puget Sound? A study of relative frequencies, growth and survival among different habitats The European blue mussel (Mytilus galloprovincialis = Mg) has become established […]

BRYAN, R.*; CLARK, M. W.; Univ. of Florida; Univ. of Florida: Wetlands birds survey: A comparison of conventional stormwater basins, enhanced stormwater basins, and natural wetlands The purpose of this investigation is to quantify the occurrence of wildlife in enhanced stormwater basins. We surveyed bird visits to the Stormwater Ecological Enhancement Project and other enhanced […]

PEREYRA, Maria Elena*; MORTON, Martin L.; University of Tulsa; University of Tulsa: Weather and predation as selective factors driving nest-site selection in two populations of dusky flycatcher We compared nest-site selection in two widely separated populations of dusky flycatcher (Empidonax oberholseri), one located in the eastern Sierra Nevada of California, at Tioga Pass (37�N), and […]

UEDA, N.*; BOETTCHER, A.A.; Univ. of South Alabama; Univ. of South Alabama: Variations in Heat Shock Protein 70 Expression Among Developmental Stages and Tissue Types in Crassostrea virginica Developmental regulation of heat shock protein (HSP) expression has been reported for insect, plant, teleost, avian, and mammalian species. In many cases, significant changes in expression occur […]
