BRANTLEY, S.*; HILL, P.S.M.: Lekking in Gryllotalpa major, the Prairie Mole Cricket: a Test of the “Hotshot Hypothesis”. Gryllotalpa major is a rare, burrowing insect indigenous to the tallgrass prairie of the south-central United States that is known to lek during mating. This study looked at possible reasons for the lekking behavior in this species. […]

Reinsel, K.A.*; Rittschof, D.; Foran, E.; Forward, Jr., R.B.: Larval release behaviors of decapod crustaceans: similar responses in shrimp and crabs Ovigerous brachyuran crustaceans respond to peptide pheromones from developing embryos with stereotyped larval release behavior. This behavior involves rhythmic motion of the pleopods (pumping), which ventilates the egg mass and facilitates hatching of the […]

MADIGAN, P.A.; WATERS, K.A.; HARRIS, L.G.*: Juvenile Growth Variation in the Green Sea Urchin, Strongylocentrotus droebachiensis: Possible Roles for Larval History, Behavior and Genetics. Growth of juvenile green sea urchins, Strongylocentrotus droebachiensis, has been observed for three year classes, 1998, 1999 and 2000. The urchins from 1998 and 1999 were collected from juvenile settlement panels […]

PIRTLE, T.J.*; SATTERLIE, R.A.: Ionic currents underlying the activity of swim interneurons of Clione limacina The marine pteropod mollusk, Clione limacina is used as a model system to study the cellular basis of locomotor speed change. Clione swim by alternate dorsal and ventral flexion of wing-like parapodia. The swim central pattern generator is located in […]

SECORD, D.*; RUPP, J.: Interpreting Marine Invasive Species for the Public: A University-Aquarium Collaboration Economic and ecological problems associated with aquatic non-indigenous species (NIS) are growing nationally and internationally. Many of these species introductions are preventable, and are caused by vectors that an informed public can do something about directly (live bait, aquaculture, and pet […]

MIDDLETON, K.M.: Influence of hallucal reversion on terrestrial locomotion in birds The reversed or opposable avian hallux (digit I) has been the subject of few anatomical or functional studies. Primitively, the theropod hallux was short and did not normally reach the substrate during locomotion, while the reversed hallux of birds represents a subsequent elongation and […]

FOWLER, E.*; HILL, P.S.M.: Individual Identification of the Prairie Mole Cricket, Gryllotalpa major. Gryllotalpa major, the prairie mole cricket, is a rare species native to the Oklahoma grasslands. Little is known about this particular species, and information is difficult to obtain because of its subterranean lifestyle. Of particular concern is our not being able to […]

EDWARDS, D.D.: Increased fluctuating asymmetry among chironomid midges in repsonse to ectoparasitic water mites: implications for fluctuating asymmetry theory. The larvae of most species of water mites must undergo a brief parasitic phase with insects to complete their life cycle. Several studies have found a significant correlation between mite load and the degree of fluctuating […]

BLACKBURN, D.G.*; JOHNSON, A.R.; PETZOLD, J.L.: Histology of the extraembryonic membranes of the oviparous corn snake, Elaphe guttata. The extraembryonic membranes of amniote eggs serve vital nutritional and respiratory functions throughout development. However, very little is known about the structure and function of these membranes in oviparous reptiles. We examined extraembryonic membranes of the corn […]

OLSON, W.M.*; HALL, B.K.: Heart morphogenesis and neural crest cell migration in cardia bifida chick embryos. During normal development, cardiac neural crest cells migrate from their position over the neural tube, through the pharyngeal region and into the heart, where they contribute to the septation of the heart and outflow tract, as well as to […]
