Invasive red lionfish Pterois volitans blow directed jets of water at prey fish

Creator:

Albins, Mark A. and Lyons, Patrick J.

Abstract:

Field and laboratory observations of feeding by invasive Pacific red lionfish Pterois volitans were conducted during June through August of 2008, 2009 and 2010 near Lee Stocking Island, Bahamas. Observations of this invasive marine predator revealed a previously undocumented piscivorous behavior. While slowly approaching prey fish, lionfish produce jets of...

Macrofaunal modification of porewater advection: role of species function, species interaction, and kinetics

Creator:

Waldbusser, George G. and Marinelli, Roberta L.

Abstract:

ABSTRACT: Sedimentary habitats are complex associations of biotic, chemical, and physical processes comprising ‘ecosystem function’. The relative importance of these processes to biogeochemical cycling in highly reactive, permeable sediments remains poorly understood. We report results from several field experiments in a muddy-sand intertidal flat dominated by 2 functionally different types...

What sets lower limits to phytoplankton stocks in high-nitrate, low-chlorophyll regions of the open ocean?

Creator:

Strom, Suzanne L., Miller, Charles B., and Frost, Bruce W.

Abstract:

Phytoplankton biomass in high-nitrate, low-chlorophyll (HNLC) ocean regions exhibits a pronounced stability: variation occurs only within a narrow range of values. The magnitude of this variation has profound ecological and geochemical consequences. While mechanisms believed to set the upper limits to HNLC phytoplankton biomass (iron limitation, microherbivore grazing) have received...

Uptake and utilization of 'colloidal DOM' by heterotrophic flagellates in seawater

Creator:

Tranvik, Lars J., Sherr, Evelyn, and Sherr, Barry F.

Abstract:

A variety of macromolecules labeled with FITC (fluorescein isothiocyanate), including carbohydrates (dextran) and proteins (ferritin, casein, albumin, concavalin A), spanning a range of molecular weights from 55 to 2000 kD, were actively ingested by marine heterotrophic flagellates at substrate concentrations of 1 to 10 mg/L. The uptake capacity for the...

Differential feeding by marine flagellates on growing versus starving, and on motile versus nonmotile, bacterial prey

Creator:

Gonzalez, Juan M., Sherr, Evelyn, and Sherr, Barry F.

Abstract:

Previous work has demonstrated selective feeding by bacterivorous protists on the of prey size. Other prey characteristics may also affect protist grazing rates. In this relative uptake rates of fluorescently labeled bacterial (FLB) cells made from starving bacteria (S-FLB), and of live-stained motile vs non-motile bacteria by marine We also...

Digestive enzyme activity as a quantitative measure of protistan grazing: the acid lysozyme assay for bacterivory

Creator:

Gonzalez, Juan M., Sherr, Barry F., and Sherr, Evelyn

Abstract:

We propose quantification of the activity of digestive enzymes as a novel way to estimate rates of protist grazing in natural waters. Our first application of this approach was determination of protistan bacterivory by assaying the activity of lysozyme at acid pH. Lysozyme specifically degrades peptidoglycan, a major structural component...

Density-dependent effects of an introduced oyster, Crassostrea gigas, on a native intertidal seagrass, Zostera marina

Creator:

Wagner, Eric, Dumbauld, Brett R., Hacker, Sally D., Trimble, Alan C., Wisehart, Lorena M., and Ruesink, Jennifer L.

Abstract:

Seagrasses and bivalves co-occur worldwide, and each plays a role in the structure, function, and services of coastal ecosystems. While seagrasses are declining, bivalve aquaculture is expanding, and impacts from culture practices, as opposed to the cultured organisms themselves, need to be distinguished. In 2 experiments, we tested the effects...

Effects of currents and tides on fine-scale use of marine bird habitats in a Southeast Alaska hotspot

Creator:

Drew, Gary S., Piatt, John F., and Hill, David F.

Abstract:

Areas with high species richness have become focal points in the establishment of marine protected areas, but an understanding of the factors that support this diversity is still incomplete. In coastal areas, tidal currents—modulated by bathymetry and manifested in variable speeds—are a dominant physical feature of the environment. However, difficulties...

Summertime foraging ecology of North Atlantic right whales

Creator:

Baumgartner, Mark F. and Mate, Bruce R.

Abstract:

North Atlantic right whales were instrumented with suction-cup mounted, time-depth recorders (TDR) during the summers of 2000 and 2001 to examine their diving and foraging behavior. Simultaneous observations of temperature, salinity and the vertical distribution of their principal prey, Calanus finmarchicus stage 5 copepodites (C5), were obtained alon g each...

Response of bacteria to simulated upwelling phytoplankton blooms

Creator:

Wetz, Michael S. and Wheeler, Patricia A.

Abstract:

Until recently, studies of the fate of primary production in coastal upwelling systems have focused mainly on export through sinking of particulate organic matter (POM). In week-long deck incubations conducted during the upwelling season off Oregon, a large accumulation of carbonrich (C:N ≥ 16) dissolved organic matter (DOM) occurred following...
