LINDER, C.J.; TSUKIMURA, B.*: Inhibitory effects of methyl farnesoate (MF) on the reproductive development of tadpole shrimp (TS), Triops longicaudatus To identify a reproductive regulator for the invasive TS, T. longicaudatus, the hormone MF was administered to growing juveniles. To administer MF, aquatic vectors (Artemia nauplii) incubated in 0.05% albumin and 5 �g/ml MF for […]

Tilden, A.R.*; Schwartz, J.; McGann, L.: Influence of Melatonin on Hemolymph Metabolites in the Fiddler Crab Uca Pugilator Melatonin levels were measured in the eyestalks of fiddler crabs (Uca pugilator) acclimated to a LD 12:12 photoperiod, constant dark, and constant light. Melatonin cycled with a photophase peak during the LD 12:12 photoperiod. The cycle persisted […]

Harper, S.L.; Reiber, C.L.: Deviants of gas exchange: adaptations of the tadpole shrimp Tadpole shrimp Triops longicaudatus inhabiting a rock pool in southern Nevada experience prolonged hypoxia. Diel oxygen concentrations (Po2) in the pool range from 0-20 kPa O2. Tadpole shrimp were reared under low (1-3 kPa) and high (10-13 kPa) Po2‘s to determine the […]

TSAI, P.-S.*; MALDONADO, T.A.; PAK, T.R.; ZHANG, L.: Characterization of a Gonadotropin-Releasing Hormone System in an Opisthobranch Mollusk, Aplysia californica Gonadotropin-releasing hormone (GnRH) is a neurohormone crucial for the regulation of reproductive and neural functions in vertebrates. Recent discoveries of GnRH immunoreactivity (IR) in a number of invertebrates raised the possibility that GnRH may be […]

VOGEL, S. : Muscle as Engine: A Biomechanical Look at Some Ancient Tasks Using muscle to power large-scale tasks presents specific difficulties. For instance, the relatively uniform size of people and draft animals imposes problems of scaling, and muscle’s inability to produce rotary motion means that non-functional mass must be accelerated and decelerated. Thus (1) […]

AMUNDSON, R.: Evo versus Devo: Methodological Conflicts in the Treatment of Variation Evolutionary and developmental biology were independent enterprises for most of the twentieth century. Differences in goals led to differences and even inconsistencies in methodologies and practices. One of the tasks of an integrative program of evolutionary developmental biology will be to negotiate these […]

EDWARDS, R.: Cultural evolution of scientific values: grant overhead in a parasite-host model. From 1968 to 1992, basic science in the United States experienced an economic condition so pervasive and significant that it was rarely acknowledged to occur. During this period, “grant overhead,” or the requested percent by which a grant budget was increased, was […]

ADELMAN, L.M.: Integration of Research and Education: Are you ready? Have you seen the new NSF guidelines? “One of the principal strategies in support of NSF’s goals is to foster integration of research and education through the programs, projects, and activities it supports at academic and research institutions. …NSF is committed to this principle of […]

HOUSEMAN, J. G. *: Incorporating digital media and new technologies into an Introductory Zoology course: Experiences and Reflections. This paper reports on seven years of personal experience on using digital media and new technologies for teaching Introductory Zoology, and looks back on some of the things that worked along with some that didn’t. University of […]

STEVENSON, R.D.: Building Conceptual Frameworks for Teaching Biology and Physiology: Theory, Examples and a New Role for SICB? A recent publication from the National Academy Press titled “How People Learn: Bridging Research and Practice” by Donovan et al. (http://books.nap.edu/html/howpeople2/ch1.html) highlights several ways to improve teaching and learning. The report states that deep factual knowledge, a […]
