Maintenance of the shore-level size gradient in the marine snail Tegula funebralis (A. Adams): Importance of behavioral responses to light and sea star predators
Abstract The intertidal gastropod, Tegula funebralis (A. Adams) exhibits a shore-level size gradient with mean shell size increasing in a down-shore direction. Snails transferred to zones where theyExpand

CHEMICAL CAMOUFLAGING AND BEHAVIORAL DEFENSES AGAINST A PREDATORY SEASTAR BY THREE SPECIES OF GASTROPODS FROM THE SURFGRASS PHYLLOSPADIX COMMUNITY
1. In Phyllospadix beds of central California, the gastropods Lacuna marmorata, Alia carinata, and Notoacmea paleacea occur in abundance with the predatory seastar Leptasterias hexactis. All threeExpand

Modification of Surface Air Over Lake Ontario in Winter
Abstract This paper attempts to estimate over-water air temperatures and dew-point temperatures between about 1 and 15 m above Lake Ontario in winter. Multivariate statistical techniques are used toExpand

Chemical mediation of invertebrate defensive behaviors and the ability to distinguish between foraging and inactive predators
When the predatory sea star Pycnopodia helianthoides was placed upstream, the sea urchin Strongylocentrotus purpuratus responded defensively by extending and opening its globiferous pedicellariae. NoExpand

Prey defense, predator preference, and nonrandom diet: The interactions between Pycnopodia helianthoides and two species of sea urchins
Interactions between the predatory sea star Pycnopodia helianthoides (Brandt, 1835) and two of its natural prey, the sea urchins Strongylocentrotus purpuratus (Stimpson, 1857) and S. franciscanusExpand

Avoidance and escape responses of the gastropod mollusc Olivella biplicata (Sowerby) to predatory asteroids
The sand-dwelling gastropod Olivella biplicata (Sowerby) gives two chemically-mediated defensive responses to predatory asteroids — an avoidance and an escape response. An avoidance response isExpand
