Feeding rates and prey : predator size ratios of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae
predator size Feeding rates and prey
2014/11/28
We studied the feeding behavior of the nauplii and adult females of the marine cyclopoid copepod Oithona
davisae in the laboratory. Functional response experiments showed that O. davisae can feed on ...
How to surprise a copepod: Strike kinematics reduce hydrodynamic disturbance and increase stealth of suction-feeding fish
Strike kinematics reduce hydrodynamic disturbance increase stealth suction-feeding fish
2014/4/17
To capture prey with suction, fish must get sufficiently close to their prey to allow the suction flow to overwhelm the prey and draw it into the mouth. Both swimming towards the prey and suction flow...
Incorporation and burial of carbon from settling cyanobacterial blooms by deposit-feeding macrofauna
Incorporation and burial of carbon settling cyanobacterial blooms deposit-feeding macrofauna
2014/4/21
Summer blooms of filamentous, nitrogen-fixing cyanobacteria are typical of the Baltic Sea, and recent findings indicate that cyanobacteria may be an important food source for the benthos below the eup...
Effect of light and feeding on the fatty acid and sterol composition of zooxanthellae and host tissue isolated from the scleractinian coral Turbinaria reniformis
Effect of light and feeding on the fatty acid sterol composition of zooxanthellae host tissue isolated scleractinian coral Turbinaria reniformis
2014/4/21
The fatty acid and sterol compositions of zooxanthellae and animal fractions of the scleractinian coral Turbinaria reniformis were investigated under different light and feeding conditions, to study t...
Tracing13 C-enriched dissolved and particulate organic carbon in the bacteriacontaining coral reef spongeHalisarca caerulea: Evidence for DOM feeding
Tracing13 C-enriched dissolved particulate organic carbon bacteriacontaining coral reef spongeHalisarca caerulea =DOM feeding
2014/4/18
Here we report on the trophodynamics of the bacteria-containing coral reef sponge Halisarca caerulea. The assimilation and respiration of the13 C-enriched substrates glucose, algal-derived dissolved a...
Simulated light regimes affect feeding and metabolism of Antarctic krill, Euphausia superba
light regimes affect feeding metabolism of Antarctic krill Euphausia superba
2014/4/22
The effect of different light regimes on physiological parameters (feeding activity, oxygen consumption, and activity of the metabolic enzyme malate dehydrogenase [MDH]) of Antarctic krill, Euphausia ...
Scaling of feeding in marine calanoid copepods
Scaling of feeding marine calanoid copepods
2014/4/23
We describe patterns of body size scaling of feeding by marine calanoid copepods based on a literature review. Maximum feeding rates of calanoid copepods, determined in the laboratory, were temperatur...
In situ feeding and metabolism of glass sponges (Hexactinellida, Porifera) studied in a deep temperate fjord with a remotely operated submersible
In situ feeding and metabolism glass sponges (Hexactinellida, Porifera) studied a deep temperate fjord remotely operated submersible
2014/4/22
Glass sponges are conspicuous inhabitants of benthic communities in the cool waters of the Antarctic and north Pacific continental shelf. We used an ROV outfitted with a new device for simultaneous sa...
Production of dissolved organic carbon by sloppy feeding in the copepods Acartia tonsa, Centropages typicus, and Temora longicornis
Production of dissolved organic carbon sloppy feeding the copepods Acartia tonsa Centropages typicus Temora longicornis
2014/4/22
With 14C-labeled phytoplankton as tracer, dissolved organic carbon (DOC) produced by sloppy feeding was measured for three species of marine copepods (Acartia tonsa, Centropages typicus, and Temora lo...
Prey-specific encounter rates and handling efficiencies as causes of prey selectivity in ambush-feeding hydromedusae
Prey-specific encounter rates handling efficiencies prey selectivity ambush-feeding hydromedusae
2014/5/4
We examined the foraging process in the jellyfish Sarsia tubulosa feeding on three types of prey: cirripede nauplii, cypris larvae, and Acartia tonsa copepodites. Clearance rate was used as measure of...
Circadian cycles in growth and feeding rates of heterotrophic protist plankton
Circadian cycles growth and feeding rates heterotrophic protist plankton
2014/5/19
Growth and feeding rates of four species of planktonic marine heterotrophic protists showed pronounced diel cycles. In most cases, rates were higher during the day and lower at night. However, for the...
Interspecific and intraspecific variation of d13C and d15N in deposit- and suspension-feeding bivalves (Macoma balthica and Cerastoderma edule): Evidence of ontogenetic changes in feeding mode of Macoma balthica
Interspecific and intraspecific variation d13C and d15N deposit- and suspension-feeding bivalves ontogenetic changes feeding mode Macoma balthica
2014/5/14
Deposit and suspension feeders can switch feeding behavior and show variations in feeding mode as individuals pass through life-cycle stages. Stable carbon and nitrogen isotopes were used to trace cha...
Oxidative coupling during gut passage in marine deposit-feeding invertebrates
Oxidative coupling gut passage marine deposit-feeding invertebrates
2014/5/14
We tested for oxidative coupling of phenolic materials, including organic contaminants and tyrosine, in gut fluid from marine deposit-feeding invertebrates. A phenolic metabolite (pyrenol) of a polycy...
Effects of Microcystis aeruginosa and purified microcystin-LR on the feeding behavior of Daphnia pulicaria
