This thesis investigated feeding behavior, cirral anatomy, Reynolds numbers (Re's), and leakiness of the cirral fan for three barnacle species: Balanus glandula, Semibalanus cariosus, and Balanus nubilus. A study of the ...
When I first arrived in the Hawaiian Islands on a teaching assignment in 1970 I naively expected to be greeted by a landscape clothed in the native flora. Instead, what I saw as I left the airport was a collage of introduced ...
Invasive species are thought to be one of the largest ecological threats to healthy ecosystems today. This paper is an attempt to show how anthropogenic transport of species with short dispersal distances is the most ...
Homing limpets are characterized by their predictable stationary resting behavior in their home territory during periods of inactivity, followed by active feeding excursions ranging up to a few meters away from home . They ...
Detritus plays an important role in the marine ecosystem. It forms a significant fraction of the available food sources (Darnell, 1958, 1961 , 1967; Gant et. al, 1971; Heald
1971; Lenz, 1977; E. P . Odum and Dela Cruz, ...

Langmuir circulation cells are wind generated surface currents, which take the form of alternating clockwise and counter clockwise rotating helical cells. Models suggest that organisms and particles may be retained in the ...
The Dall porpoise (Phocoenoides dalli True) is a small, deep-bodied and easily identifiable cetacean found in the northern North Pacific Ocean and adjacent waters including the Gulf of Alaska, Bering Sea, Sea of Okhotsk, ...
Cyanobacteria are thought to have evolved during the early Precambrian, 2.5-3.8 billion years ago, when there were very high levels of UV radiation reaching the Earth's surface due to a lack of absorbing gases int he ...

Saddle Rock, with an estimated 86,300 birds, was the third largest colony of
Leach's Storm-petrels (Oceanodroma leucorhoa) in Oregon in 1988. This colony is
uniquely vulnerable to terrestrial predation due to its contiguity ...
