STEWART, H.L: Morphological heterogeneity among zooids of encrusting colonies of Membranipora membranacea induces passive flow through the colony. Encrusting bryozoans live in a velocity gradient at the base of momentum boundary layers in the fluid environment in which they live. As suspension feeders, their interaction with the surrounding fluid is important in filter-feeding success, which […]

ERNST, H.H.*; RICHARDSON, J.F.; SATTERLIE, R.A.: Morphological Changes in an Asymmetric Neuron of the Right Pleural Ganglion in the Sexually Mature Vs. Immature Pteropod Mollusk One of the largest neuron somata of the right pleural ganglion of Clione limacina belongs to a cell that does not have a homologue in the left pleural ganglion. In […]

Pavlov, V.: Morphological Adaptation of Dorsal Fin of Harbour Porpoise (Phocoena phocoena) to Swimming and Thermal Regulation Function Dorsal fin is an example of particular specialization of an organ having combined function of stabilization of motion and heat regulation. The shape of the fin was evaluated by the set of wing and foil parameters: angle […]

MABEE, P.M.; CROTWELL, P.L.*; BIRD, N.C.: Models to explain directions of development and evolution of fin skeletons. Data on development of radials and rays of median (dorsal, anal, caudal) and paired (pectoral, pelvic) fins were compared within a phylogenetic framework. We found broadly conserved phylogenetic patterns in directions of development within the different median and […]

Budick, S.B.*; O’Malley, D.M.: Minimal Behavioral Deficits Are Observed After Laser-ablation of the nMLF in Larval Zebrafish Larval zebrafish exhibit a range of locomotive behaviors including swimming, turning and escaping. These behaviors are controlled by a relatively small group of brainstem neurons including cells of the nucleus MLF (nMLF) plus reticulospinal, vestibulospinal and T-reticular neurons. […]

CASOTTI, G.: Microvilli within the lower intestine of sparrows Tissue from the lower intestine of two species of sparrow, the house sparrow Passer domesticus and savannah sparrow Passerculus sandwichensis was sectioned in an unbiased manner and examined quantitatively using stereology. The tissue was processed for light microscopy, and scanning and transmission electron microscopy to examine […]

FUDGE, D.S.*; GOSLINE, J.M.: Mechanical and Optical Properties of Hagfish Slime Threads Hagfishes are unique in their ability to produce vast quantities of fiber-reinforced slime when they are provoked. In order to understand the material properties of hagfish slime, we investigated the properties of isolated slime threads from the Pacific hagfish (Eptatretus stouti). The threads […]

SHADWICK, R.E.; SYME, D.A.*: Mechanical Power Production by Red and White Swimming Muscles of Yellowfin Tuna (Thunnus albacares) The mechanical performance of red and white muscle from yellowfin tuna was studied in vitro at 25oC using the work loop technique. Fibers from internal red muscle were taken from two axial locations, 0.5L and 0.65L (L=total […]

Korzan, W.J.*; Summers, T.R.; Miner, H.M.; Martin, M.L.; Flynn, M.B.; Summers, C.H.: Manipulating a Visual Signal of Sympathetic Activity: Influences on Social Status and Plasma Catecholamines Darkening of postorbital skin in Anolis carolinensis occurs during stressful situations, and is stimulated by adrenal catecholamines via BETA2-adrenergic receptors. This eyespot forms more rapidly in dominant males during […]

ARDELEAN, A.*; FAUTIN, D.G.; HUNSINGER, K.: Managing taxonomic synonyms Multiple names that refer to a single species (synonyms) and more than one species being referred to by the same name (homonyms) bedevil taxonomy. They produce ambiguity about the entity under discussion. We demonstrate an electronic application that helps organize information about synonyms and homonyms. Output […]
