GOBALET, K. W.: Archaeological Evidence for Steelhead Oncorhynchus mykiss in the Coastal Streams of California from San Francisco to Mexico Southern populations of salmon and trout (family: Salmonidae) are in dramatic decline. Conservation and legal issues surround whether or not salmon and trout are native to coastal streams of California. Since authoritative surveys of the […]

WILLIAMSON, C.A.*; MARKS, J.C.; HENDRICKSON, D.A.; SWANSON, B.O.: Aliens invade Mexico: proof of their impact on native cichlids The basin of Cuatro Ciénegas, with over 200 springs and pools, lies in the Chihuahuan desert of northern Mexico. The area is a high priority conservation site with many endemic fishes and mollusks. Although geographically isolated, the […]

JOYNER, J.L.*; LEE, R.W.: The role of sulfur-containing amino acids in sulfide detoxification by chemoautotrophic bacteria-mollusc symbioses Molluscs living at hydrothermal vents and in reducing sediments are exposed to high levels of the metabolic toxin, hydrogen sulfide. Many of these molluscs harbor intracellular chemoautotrophic bacteria. The symbiotic bacteria oxidize hydrogen sulfide to power the fixation […]

NYHOLM, SV; DEPLANCKE, B; GASKINS, HR; APICELLA, M; MCFALL-NGAI, MJ: The role of mucus secretion in the harvesting of symbionts during colonization of a squid light organ The Hawaiian bobtail squid Euprymna scolopes is colonized each generation by the bioluminescent bacterium Vibrio fischeri. During colonization, host-derived ciliary currents and mucus secretions aggregate Gram-negative bacteria outside […]

STEWART, J.J.; NYHOLM, S.V.; MCFALL-NGAI, M.J.: Squid hemocytes are able to discriminate the specific symbiont from other types of bacteria. The establishment of the light organ symbiosis between the Hawaiian bobtail squid Euprymna scolopes and the marine luminous bacterium Vibrio fischeri depends on specific selection for the bacterial symbiotic partner and exclusion of other potentially […]

GOODSON, M.S.*; KIMBELL, J.R.; MCFALL-NGAI, M: Characterization of a p53-like protein in the morphogenesis of a light organ symbiosis The sepiolid squid Euprymna scolopes forms a specific, environmentally transmitted, light organ symbiosis with the luminescent bacterium Vibrio fischeri. On infection with V. fischeri, the juvenile light organ undergoes morphogenic change resulting in the loss of […]

BHAGOOLI, R.; ARCHER, J.; ZIELKE, S.; TRAPIDO-ROSENTHAL, H.*: Zooxanthellae Released from the Coral Stephanocoenia intersepta During Heat-Induced Bleaching Have Elevated Levels of Nitric Oxide Synthase Activity Zooxanthellae (zoox) released from the coral Stephanocoenia intersepta during heat-induced bleaching possess elevated levels of nitric oxide synthase activity. Coral bleaching, in which corals lose their photosynthetic symbionts, is […]

OKAMURA, BETH; CURRY, ALAN; WOOD, TIMOTHY S.; CANNING, ELIZABETH U.: Worms to sacs: Buddenbrockia reveals bilaterian origins of the Myxozoa Buddenbrockia is an enigmatic, worm-like parasite of freshwater bryozoans which was first described in the 19th century. It has since been reported infrequently and its phylogenetic affinities have remained obscure. The discovery of Buddenbrockia parasitic […]

MEAGHER, S.*; DUDEK, S. N.: Physiological consequences of Trichinella spiralis (Nematoda) infection on oldfield mice (Peromyscus polionotus) Trichinella spiralis is a nematode parasite that infects many mammals, including humans. Significant physiological changes or death can result in the host due to acute inflammatory immune responses toward the parasite. Little research has been conducted on the […]

WILCOX, Thomas P.; SLOAN, Adrienne J.; BISSEL, J.: Experimental Evidence for the Evolution of Cheating in an Algal:Invertebrate Symbiosis The role of cheating symbionts in algal:invertebrate symbiosis has been largely ignored, but theoretical studies suggest they may play a significant role in the evolution of these associations. This is particularly true in symbioses in which […]
