An ecological study of Diatomovora amoena, an interstitial acoel flatworm, in an estuarine mudflat on the central coast of Oregon

Creator:: Thum, Alan Bradley
Abstract:: The distribution and abundance of the interstitial acoel turbellarian, Diatomovora amoena Kozloff, 1965 was studied in an estuarine intertidal sand flat in Yaquina Bay, Oregon, from May 1970 through May 1971. Monthly measurements of biological (organics, sulfides, chlorophyll, and carotenoids), pore water (salinity, pH,oxygen, and temperature), and sediment (fine sediment...

Dynamics of crab larvae (Anomura, Brachyura) off the central Oregon coast, 1969-1971

Creator:: Lough, Robert Gregory, 1943-
Abstract:: Bimonthly plankton samples were collected from 1969 through 1971 along a transect off the central Oregon continental shelf (44° 39. l'N) to document the species of crab larvae present, their seasonality, and their onshore-offshore distribution in relation to seasonal changes in oceanographic conditions. A comprehensive key with plates is given...

Behavioral aspects of righting in the asteroid echinoderms Henricia leviuscula (Stimpson) and Leptasterias aequalis (Stimpson)

Creator:: Polls, Irwin
Abstract:: Righting behavior was examined in the asteroids Henricia leviuscula and Leptasterias aequalis by repeating a standard laboratory righting trial with a large number of individuals of each species, and analyzing the observations made by statistical methods. Detailed observations on the righting method, including leading pairs of arms and righting time...

The effects of temperature and salinity on the early development of Adula californiensis (Pelecypoda-Mytilidae)

Creator:: Lough, Robert Gregory
Abstract:: Adula californiensis, which inhabits mudstone along the open coast and in Yaquina Bay, Oregon, is subjected to extremely varying conditions. Laboratory experiments of a factorial design were used to investigate the effects of temperature and salinity on survival, growth and respiration during early development. The rate of development to the...

Tidal exchange of decapod larvae and small benthic peracarids between the ocean and the Salmon River estuary, Oregon

Creator:: Gonzalez, Exequiel
Abstract:: Zooplankton samples taken during daylight periods in a fast flushing estuary on the Central Oregon coast were analyzed for Brachyuran and Anomuran larvae and also for benthic gammaridean amphipods and Myscidacea. Several larval stages of Pinnixa littoralis, Hemigrapsus oregonensis, Pachycheles spp., Cancer oregonensis and Pagurus granosimanus were sufficiently abundant for...

The tidal exchange of Callianassa californiensis larvae between the ocean and the Salmon River estuary, Oregon

Creator:: Johnson, Gary Ellis
Abstract:: During the Callianassa californiensis larval release period, weekly zooplankton samples were taken through daylight tidal cycles near the mouth of a small, fast flushing estuary on the Central Oregon coast. Although C. californiensis adults are confined to estuaries and embayments, stage I zoeal larvae were shown to be exported from...

Seasonal gametogenesis and egg laying in the prosobranch gastropods Nucella lamellosa, Nucella emarginata, Searlesia dira and Amphissa columbiana on the Oregon coast

Creator:: Seavy, Donald Keith
Abstract:: A 15-month field study was made on the reproductive cycles of the prosobranch gastropods Nucella lamellosa, Nucella emarginata, Searlesia dira and Amphissa columbiana on the Oregon coast. Amphissa columbiaria and Searlesia dira were collected from Boiler Bay, Nucella emarginata from Seal Rock and Nucella lamellosa from inside Yaquina Bay. All...

Ecology and reproductive biology of Tonicella lineata (Wood, 1815) (Mollusca - Polyplacophora)

Creator:: Barnes, James R.
Abstract:: Along the central and southern Oregon coast and on San Juan Island, Washington, the lined chiton Tonicella lineata is very abundant in the lower intertidal levels on rocky shores. It is usually found on encrusting coralline algae which, with epiphytic diatoms, make up the major portion of its diet. On...
