SILVERTHORN, D.U.; Univ. of Texas, Austin: Discovering What Students Know: High-Tech and Low-Tech Alternatives Finding out what students are learning before they take an examination allows instructors to clarify points of confusion and address student misconceptions. In large lecture settings, however, this can be a challenging task. Dialogue between the instructor and students often is […]

HURNEY, Carol A; BABCOCK, Sharon K; PESCE, Andrea; James Madison University; James Madison University; James Madison University: A Novel, Integrative Approach to Introductory Biology Recent curriculum reform at JMU resulted in the implementation of four introductory courses focused on (1) Fundamental Processes of Organisms , (2) Evolution and Ecology, (3) Cell and Molecular Biology, and […]

HOLFORD, KC; LI, S; BORST, DW; Purdue Univ. North Central; Illinois State Univ.; Illinois State Univ.: Regulation of the methyl farnesoate biosynthetic pathway in the lobster mandibular organ. Methyl farnesoate (MF) is a major product of the crustacean mandibular organ (MO). The synthesis of this isoprenoid is regulated by neuropeptides from the sinus gland (SG) […]

LAUFER, HANS*; DEMIR, NESLIHAN; AHL, JONNA/S.B.; University of C onnecticut, Storrs; University of Connecticut, Storrs; Eli Lilly, Indianapolis: Male Morphotypes of the Crayfish Procambarus clarkii are Controlled by Methyl Farnesoate Adult male crayfish exist in two morphotypes. Primary reproductives (Form I) have large spiny chelae and spines on the ischiopodites of the third and fourth […]

TAMONE, S.L.; DUTTON, J.M.; Univ of Alaska SE: Effect of eyestalk ablation on circulation ecdysteroids in snow crab, Chionoecetes opilio: evidence for a terminal molt. Snow crab, Chionoecetes opilio are a commercially important crab fished in the Bering Sea and Canada. The management of this species requires a better understanding of their molting biology. C. […]

BOETTGER, Stefanie A; RICKETTS, Bryon F; SAHLER, Christopher S; WALKER, Charles W; Univ. New Hampshire, Durham; Univ. New Hampshire, Durham; Univ. New Hampshire, Durham; Univ. New Hampshire, Durham: Cytoplasmic sequestration of p53 family member proteins by heat shock protein family member mortalin II in leukemic clam hemocytes. Mechanisms causing cytoplasmic sequestration and inactivation of the […]

HOPKINS, P.M.; DURICA, D.S.; WU, X.; University of Oklahoma: Binding Properties of the crustacean ecdysteroid receptor UpEcR/RXR from the fiddler crab, Uca pugilator . Growth, reproduction, and regeneration in the fiddler crab,Uca pugilator, are thought to be regulated by a suite of hormones � the ecdysteroids. These polyhydroxylated steroids exert their influence through interactions with […]

CHRISTENSEN, D.E. *; VLECK, C.M.; Iowa State Univ., Ames: Lactotroph Distribution and Response to VIP Stimulation Across the Breeding Cycle in the Zebra Finch In arid regions of Australia, Zebra Finches are opportunistic breeders whose breeding cycles are coupled to nonseasonal rainfall rather than photoperiod, requiring them to be reproductively competent on short notice. We […]

PEREYRA, M.E.*; SHARBAUGH, S.M.; HAHN, T.P.; U.C. Davis; U. of AK, Fairbanks; U.C. Davis: Interspecific variation in photo-induced hypothalamic GnRH plasticity in cardueline finches In this study, we present data on photo-induced changes in hypothalamic GnRH immunoreactivity associated with the development of refractoriness in males of 3 closely related species of cardueline finch: common redpoll, […]

SCHOECH, S. J.*; BOWMAN, R.; REYNOLDS, S. J.; U. of Memphis, TN; Archbold Biol. Stn., Venus, FL; U. of Birmingham, Edgbaston, UK: Interactions Between Nutrition, Corticosterone, and Reproduction in Florida Scrub-Jays In variable environments animals often exhibit interyear variation in the timing of breeding. Study of two populations of Florida Scrub-Jays (Aphelocoma coerulescens) in the […]
