CHUNG, K.F.*; LIN, H.C.; Tunghai University; Tunghai University: Osmoregulation and Na, K-ATPase Expressions in Osmoregulatory Organs of Scylla paramamosain Scylla paramamosain is a euryhaline marine crab that can regulate its hemolymph osmolality actively and survive in a wide range of salinity. In order to reveal the relationship between environmental salinity and its osmoregulatory organs, we […]

DICKIE, R; Harvard University: Normal and aberrant angiogenesis in the brain: morphological consequences of genotypic differences in neural stem cells and the role of hypoxia There are common molecular and morphological themes in the development of normal and neoplastic glia; here we focus on those associated with the vasculature. During embryonic development, vascular sprouts penetrate […]

SHERRARD, KM*; MUNRO, EM; BECKHAM, Y; ODELL, GM; Univ. of Washington, Seattle; Univ. of Washington, Seattle; Univ. of Washington, Seattle; Univ. of Washington, Seattle: New wrinkles: Cytoskeletal mechanics of endoderm invagination Invagination, the folding inwards of a formerly flat epithelium, is a common and fundamental mode of morphogenesis. Invagination operates during gastrulation, neurulation, eye formation, […]

These changes are primarily […]

CROLL, RP; HOCHBERG*, R*; Dalhousie University, Nova Scotia; Smithsonian Marine Station, FL: Neomeniomorpha-Solenogastres (Aplacophora): Insights into the Neuromuscular System of Primitive Mollusca Neomeniomorpha (Solenogastres) is a small and monophyletic taxon of marine, shell-less molluscs that share a potentially primitive phylogenetic position with species of Chaetodermomorpha (Caudofoveata). Species of both clades are poorly cephalized, wormlike, and […]

SCHMAEMAN, C.N.*; VONHOF, M.J.; MENDON�A, M.T.; Auburn Univ.., Auburn, AL; Western Michigan Univ., Kalamazoo, MI; Auburn Univ., Auburn, AL: Multiple Mating and Paternity Outcomes in Big Brown Bats: A Preliminary Study Very little is known about the mating systems of temperate vespertilionid bats. What is known is that temperate vespertilionids can store sperm for an […]

MARTIN, G.G.; WILKINSON, H.; Occidental College, Los Angeles; Occidental College, Los Angeles: Morphology and Function of the Hemocytes in Aplysia californica We are interested in how environmental factors affect the physiology and immune responses of marine invertebrates. Presently we are trying to characterize the effects of temperature on the number and function of circulating hemocytes […]

JOHNSON, G.P.; DANGLE, D.D.; WOLFE*, A.F.; Lebanon Valley College; Lebanon Valley College; Lebanon Valley College: Morphological Study of Artemia Hemocytes During the Molting Cycle Although most crustaceans have several different types of blood cells, the anostracan, Artemia franciscana, has a single type of granular hemocyte in its hemolymph. Using various stains, microscopic techniques, and gel […]
