Temple, J. G.: Animal Magnetism: Using magnetic stir bars to learn about digestive passage rate in snakes. Snakes, as classic ectotherms, are interesting subjects for studying the relationship between temperature and physiological processes. They are particularly well-suited for studying digestive passage rate given the linear anatomical arrangement of their digestive tracts. In this paper, a […]

MORSE, M.P.: AIBS/Packard Review of High School Biology Instructional Materials Ten sets of instructional materials currently used in high school biology courses across the nation were reviewed by a 9-person team of scientists, science educators and teachers. This team developed the AIBS/Packard review instrument and conducted the review over a period of 18 months. The […]

VEZINA, F.*; WILLIAMS, T.D.: What drives the metabolic cost of egg production? Preliminary data from a study on egg production in European starlings showed a positive correlation between resting metabolic rate (RMR) and plasma levels of the two main yolk precursors, vitellogenin (VTG) and very low density lipoprotein (VLDL). At that time we suggested that […]

SEPULVEDA, Chugey A.; GRAHAM, Jeffrey B.: The swimming energetics of the eastern Pacific bonito (Sarda chiliensis): One step closer to understanding the tuna-bonito relationship Fishes in the family Scombridae have morphological adaptations for fast, efficient locomotion. The most derived scombrids, the tunas (tribe Thunnini), appear to further increase swimming efficiency by elevating aerobic locomotor muscle […]

SECOR, S.M.: The source and sense of the metabolic response to feeding Specific dynamic action (SDA) is the collective energy expended on the ingestion, digestion, absorption, and assimilation of a meal. Known is that SDA is initially fuel by endogenous energy stores, that SDA varies with meals size and composition, and that the magnitude of […]

FINKLER, MS; CULLUM , KA: Interspecific and sex-related differences in metabolism and post-reproductive energy reserves in spring-breeding Ambystomid salamanders. We investigated potential differences in post-reproductive metabolism and energy reserves between male and females of three species of spring breeding Ambystomid salamanders (Ambystoma maculatum, A. texanum, and A. tigrinum). Size-adjusted O2 consumption rates did not differ […]

TAYLOR, E.N.*; DENARDO, D.F.: Growth of juvenile western diamondback rattlesnakes (Crotalus atrox) raised on different diets We examined the effect of food intake on growth parameters in juvenile western diamondback rattlesnakes (Crotalus atrox). Fifty snakes were captured from the wild shortly after birth and housed individually in the laboratory. Snakes were randomly assigned to “high […]

CAIN, S.D.; WOODWARD, O.H.; Friday Harbor Labs, Univ of Washington; Friday Harbor Labs, Univ of Washington: The use of multiple transmitters controlling ciliary beating on the foot on the sea slug, Tritonia diomedea The use of cilia in locomotion is limited to a few large, marine animals, most of which are nudibranchs. However, unlike muscular […]

PALMER, L. M.; MENSINGER, A. F.; University of Minnesota, Duluth; University of Minnesota, Duluth: Sensitivity of the anterior lateral line to complex stimuli in free swimming Oyster Toadfish, Opsanus tau The lateral line of fishes consists of mechanoreceptive hair cells that function in schooling behavior, localization of underwater objects, rheotaxis and prey detection. Hair cells […]
