Hamilton, H.C.*; Garey, J.R.: Applying Molecular Techniques to Environmental Studies of Meiofauna The purpose of this study is to develop sequence tags for a set of marine meiobenthic fauna (meiofauna). We have shown that DNA of meiofaunal origin can be extracted directly from sediment samples. We have also shown that primers for the 18S rRNA […]

Clark, T.M.*; Hutchinson, M.J.; Moffett, D.F.: Apical surface morphology of the stomach region of the larval mosquito midgut. Mature 4th instar larval Aedes aegypti measuring 6.5�0.19 mm in length have a stomach region of 3.3�0.18 mm (N=6). The stomach is clearly differentiated into distinct anterior, transitional and posterior regions (53.0�1.16%, 13.7�1.16%, and 33.3�0% of total […]

Trinachartvanit, W.; DeVries, A.L.; Cheng, C.- H. C.: Antifreeze glycoproteins (AFGPs) are secreted into the digestive tract from the pancreas in Antarctic notothenioid fishes. Pancreatic tissues in teleost fishes are diffuse unlike other vertebrates. In the large Antarctic notothenioid fish Dissostichus mawsoni a small reservoir exists at the terminus of the pancreatic tissue duct system […]

Stoddard, S.T.; Jin, Y.; Cheng, C.H.*; DeVries, A.L.: Antifreeze Potentiating Protein in Antarctic Notothenioid Fishes The ability of Antarctic notothenioid fishes to survive in ice-laden waters at -1.9oC has been attributed to a group of antifreeze glycoproteins (AFGPs). In the absence of AFGPs, the freezing point of body fluids in the fish would be approximately […]

Pressman, E.*; Temple, J. G.: An Examination of the Thermoregulatory Response of the Garter Snake Thamnophis radix radix to the bacterium Aeromonas hydrophila Research has shown that certain species of ectotherms behaviorally induce a fever in response to an infection. Research has also shown that the garter snake Thamnophis sirtalis shows a hypothermic response to […]

HAMMOND, K.A.*; KRISTAN, D.M.; CHAPPELL, M.A.: Aerobic performance in deer mice (Peromyscus maniculatus) Limits to whole-animal performance may be a result of peripheral effectors, central supportive organs, or both (“symmorphosis”). We examined these concepts using aerobic performance in deer mice (Peromyscus maniculatus). We correlated the masses of peripheral (foreleg and hind leg muscles) and central […]

TOWLE, D.W.: A Proposal to Establish CRABinfo, a User-Directed Database for Crustacean Bioinformatics. The crustacean research community is invited to respond to a proposal to establish the Crustacean Research And BioINFOrmatics database, CRABinfo. Modeled after successful internet projects such as FlyBase and the Zebrafish Information Network (ZFIN), CRABinfo seeks to support and enhance research activities […]

BAGATTO, B.*; WOLOSZYN, L.; BURGGREN, W.: 3-D Visual Assessment of Cardiovscular Function in Zebrafish Larvae Numerous investigators are now measuring stroke volume of developing vertebrates by optical examination. The standard method for many animals, including zebrafish larvae, involves fixing the larvae, and capturing two dimensional video of lateral views of the beating heart through an […]

SCHILDER, R.J.; MARDEN, J.H.: Workloop Force and Lever Arm Length Allometry in Dragonfly Flight Motors Maximum isometric muscle force production scales as muscle mass2/3, whereas maximum net force output by flying animals scales isometrically with total flight muscle mass. What causes this transition between the two scaling relations? We examined this question by subjecting dragonfly […]

ARONOWSKY, A.: What is the function for sediment incorporation in naticid gastropod egg masses? Naticid gastropods are the only molluscs that incorporate large amounts of local sediment in the construction and sealing of their unique egg masses, called egg collars. Phylogenetic analysis suggests the use of sediment is the basal condition for naticids and might […]
