RICHARDSON, J.F.; SATTERLIE, R.A.: Ultrastructural comparison of the pleural white cells in immature and mature specimens of the pteropod mollusc Clione limacina. The pteropod mollusc Clione limacina exhibits asymmetrical nervous system development during sexual maturation. The pleural white cell is an asymmetric cell in the right pleural ganglia with one of the largest somata in […]

SHERRARD, K.M.: Transient Lilliputians: Suspension feeding performance in early juvenile sea squirts (Tunicata: Ascidiacea). Early juvenile stages of marine invertebrates typically experience high mortality. The causes remain obscure, but nutritional stress is likely to play a role. Sea squirts include solitary species whose juveniles begin suspension feeding at a length of 200 microns, and grow […]

BUFFENSTEIN, R.*; WOODLEY, R.: Thermogenic responses to cold acclimation in naked mole-rats; evidence for central constraints limiting metabolism. Naked mole-rats (Heterocephalus glaber) are hairless rodents that exhibit an unusual endothermic yet poikilothermic mode of thermoregulation. We questioned why this may be the case and how these animals respond to cold acclimation (CA). Specifically we asked […]

FITZHENRY, Tara; GARDNER, Kristi; HELMUTH, Brian: The steamy side of intertidal life: do Mytilus californianus gape to evaporatively cool? Rocky intertidal mussels Mytilus californianus can be exposed to potentially damaging thermal conditions during low tide. One potential mechanism for alleviating the effects of thermal stress is to evaporatively cool by gaping, a behavior that also […]

JOST, Jennifer A: The risk of freezing in an intertidal polychaete: effects of salinity and sediment depth This study focuses on the freeze tolerance of the marine polychaete worm, Nereis virens. The risk of exposure of these worms to freezing temperatures was explored as a function of both salinity and sediment depth. By slowly bringing […]

XING, Bin; SHEARER, Joesph; COOPER, Robin L.: The influence of culture media on synaptic transmission at larval Drosophila neuromuscular junction The larval Drosophila neuromuscular junction (NMJ) has proven to be a excellent testing ground for understanding key aspects in the fundamentals of synaptic transmission in relation to the function of ion channels, subtypes of glutamate […]

MODRALL, JENNIFER*; WHEELER, TERRI; POKRAS, MARK; ROMERO, L. MICHAEL: The impact of veterinary administration of antibiotics on the bacterial ecology of wild bird populations This study investigated whether veterinary uses of antibiotics have altered the bacteria ecology within surrounding wild bird populations. Antibiotics have been commonly used in animal husbandry for over 30 years. There […]

COATES, M.M.*; THOMPSON, S.H.; NILSSON, D.-E.: The image forming capabilities of the camera-type eyes of a box jelly, Tripedalia cystophora Although box jellies (class Cubozoa) are traditionally thought to be simple animals they possess amazingly complex visual hardware. First described over 100 years ago (Conant, 1898), the 24 eyes on a box jelly are of […]

DEBAN, S.M.; OTTERSTROM, J.; CARRIER, D.R.: The face that sunk the Essex In the 19th century, sperm whales (Physeter macrocephalus) were prized commercially for the high quality oil contained in their derived and greatly enlarged melon, known as the spermaceti organ, and also feared by whalers because of their aggressive behavior. Herman Melville’s (1851) fictional […]

LOPEZ, C.M.*; GORTON, M.J.; HOYT, D.F.; COGGER, E.A.; WICKLER, S.J.: The energetic cost and time of contact with added limb mass in trotting horses. Although the metabolic cost of accelerating and decelerating the limbs during terrestrial locomotion appears to be minimal, studies on humans and quadrupeds (dogs and horses) demonstrate a disproportionate increase in the […]
