Copepods are major consumers of sinking marine particles and hence reduce the efficiency of the biological carbon pump. Their high abundance on marine snow suggests that they can detect sinking particles remotely. By means of laboratory observations, we show that the copepod Temora longicornis can detect chemical trails originating from sinking marine snow particles (appendicularian houses). The chemical cue was detected by copepods from a distance of >25 particle radii, with the probability of… 

Copepod Grazing Influences Diatom Aggregation and Particle Dynamics

Carbon export is driven by particle flux which is modulated by aggregation, remineralisation and grazing processes. Zooplankton contribute to the sinking flux through the egestion of fast sinking

Perceiving the algae: How feeding‐current feeding copepods detect their nonmotile prey

It is concluded that near-field mechanoreception is the common prey detection mode in pelagic copepods and prey detection distances are governed mainly by the reach of the feeding appendages, in contrast to the strong prey size-dependency implied by remote chemical prey detection.

Functional responses of aggregate‐colonizing copepods

Zooplankton consumption of aggregates, such as marine snow, is an important factor in determining the efficiency of the biological carbon pump. However, the feeding rates of aggregate‐associated

Mechanisms of prey size selection in a suspension-feeding copepod, Temora longicornis

The mechanistic underpinning of the prey size spectrum suggested here deviates from previous descriptions mainly in the mechanism and range of prey detection.

Active Sinking Particles: Sessile Suspension Feeders significantly alter the Flow and Transport to Sinking Aggregates

This work uses a novel scale-free vertical-tracking microscope to follow model sinking aggregates with attached protists, finding that activity generated by attached Vorticella cause substantial changes to the flow around aggregates in a dynamic manner and reshape mass transport boundary layers.

Zooplankton eat what they need: copepod selective feeding and potential consequences for marine systems

It is demonstrated that a combination of stage-specific selective feeding and body stoichiometry has the potential to affect cycling of limiting nutrients when consumer populations change in composition.

Feeding on dispersed vs. aggregated particles: The effect of zooplankton feeding behavior on vertical flux

The zooplankton species composition combined with the type of available food strongly influences the calculated carbon demand of a copepod community, and thus also the attenuation of vertical carbon flux.

Aggregate Feeding by the Copepods Calanus and Pseudocalanus Controls Carbon Flux Attenuation in the Arctic Shelf Sea During the Productive Period

Up to 95% of the oceanic primary production is recycled within the upper few hundred meters of the water column. Marine snow and zooplankton fecal pellets in the upper water column are often recycled

The effect of phytoplankton properties on the ingestion of marine snow by Calanus pacificus

Abstract Marine snow, formed through the aggregation of phytoplankton and other organic matter, can be consumed by various types of zooplankton, affecting both planktonic trophic dynamics and the



Benthic life in the pelagic: Aggregate encounter and degradation rates by pelagic harpacticoid copepods

High short-term hunger-induced feeding rates observed in A. normanni indicate that at least some harpacticoid species can fill their gut during few short visits to aggregates, and may cause substantial degradation of aggregates when their abundance exceeds 10 5 m 22 , which is not atypical during summer in temperate waters.

Colonization of marine snow aggregates by invertebrate zooplankton: Abundance, scaling, and possible role

Observations of abundances of invertebrate zooplankters associated with marine snow aggregates in the euphotic zone found different taxonomic groups showed different affinities for aggregates and copepods and crustacean nauplii were the dominant groups on aggregates.

The fate of discarded appendicularian houses: degradation by the copepod, Microsetella norvegica, and other agents

The model results suggested that the vertical distribution of houses was shaped by sinking of houses, bacterial degradation and feeding of M. norvegica and invertebrate larvae, and its role in marine snow degradation is likely to be small.

Midwater zooplankton communities on pelagic detritus (giant larvacean houses) in Monterey Bay, California

The results suggest that midwater detritus contains a unique invertebrate community that has been largely undetected, mostly due to sampling difficulties, and also provides benthiclike habitats for midwater zooplankton and serve as feeding centers.

Influence of diet on copepod survival in the laboratory

It is suggested that, in low food environments, food quantity and species-specific ability to resist starvation might be as important as food quality in determining the success of copepod populations.

Fluid motion and solute distribution around sinking aggregates. II. Implications for remote detection by colonizing zooplankters

From the model of the plume and literature-based estimates of size-dependent aggregate leakage rates of amino acids, it is estimated that a threshold sensitivity to amino acids of 0.4 〈 10 -7 M is required to account for observed abundances of colonizers, consistent with knowledge of the amino acid concentrations needed to elicit behavioral responses in copepods.

Characteristics of the chemical plume behind a sinking particle in a turbulent water column

Many aquatic organisms, from bacteria to crustaceans, use chemical plumes released by sinking particulate organic material either directly as a food source or as a signal to find potential food items

Production, oxygen respiration rates, and sinking velocity of copepod fecal pellets: Direct measurements of ballasting by opal and calcite

This study directly demonstrates that ballast increases the sinking rate of freshly-produced copepod fecal pellets but does not protect them from decomposition.
