...Patrick J. Krug; Jeffrey A. Riffell; Richard K. Zimmer SUMMARY Red abalone ( Haliotis rufescens ) sperm detect a waterborne chemical cue released by conspecific eggs, and change their swimming behavior to increase the likelihood of fertilization success. Previously, we isolated the natural sperm...

...Norman L. C. Ragg; H. Harry Taylor SUMMARY The abalone Haliotis iris retains the ancestral gastropod arrangement of a pair of bipectinate gills (ctenidia). The gills share a single branchial chamber, are supplied from a common haemolymph sinus and effectively support the whole of oxygen uptake...

...,but such compounds are largely undescribed. This investigation considered the behavioral responses of red abalone ( Haliotis rufescens ) sperm to soluble factors released into sea water by conspecific eggs. Sperm in proximity to individual live eggs swam significantly faster and oriented towards the egg surface...

...Deborah A. Donovan; Thomas H. Carefoot ABSTRACT Morphological analyses of pedal sole area and pedal waves were conducted for a range of speeds and body sizes in the abalone Haliotis kamtschatkana . The pedal sole of resting abalone increased in size disproportionately with animal volume (slope...

...Elizabeth Dahlhoff; George N. Somero ABSTRACT We measured the effects of temperature on cytosolic malate dehydrogenases (cMDHs) from the shell muscle of five species of eastern Pacific abalone, genus Haliotis , found at different latitudes and/or tidal heights. The apparent Michaelis–Menten...

...Elizabeth Dahlhoff; George N. Somero ABSTRACT The effects of temperature on mitochondrial oxygen consumption, membrane fluidity and cytochrome c oxidase activity were measured for five species of eastern Pacific abalone (genus Haliotis ) found at different latitudes and tidal heights. Mitochondria...
