This work focuses on the formation of mating aggregates in zooplankton. In particular, sexual encounters are behaviourally supported by males actively swimming in search for females, and approaching them for mating once they are found. While the random search leads to a diffusive flux of individuals, the approaching for encounter supports attraction. Thus, we ask whether these competing mechanisms of diffusion and attraction can support aggregation and lead to the formation of mating clusters. To…

Efficient mate finding in planktonic copepods swimming in turbulence
TLDR
This work reconstructs simultaneously the trajectories of flow tracers and calanoid copepods and quantifies their ability to find mates when ambient flow imposes physical constrains on their motion and impairs their olfactory orientation.
Motility patterns and mate encounter rates in planktonic copepods
TLDR
It is shown that pelagic copepods are capable of searching tens to thousands of liters of ambient water for mates daily, that search capacity increases approximately with the cube of copepod length for both chemical and hydrodynamic signalers, and that these impressive mate search volume rates are sufficient to sustain populations at typical adult densities.

The impact of rheotaxis and flow on the aggregation of organisms
TLDR
A mathematical model is developed that demonstrates that each of flow and rheotaxis can act beneficially or detrimentally on the ability to form and maintain a cluster, and test a hypothesis that density-dependent rheOTaxis may be optimal for group formation and maintenance.
Motility of zooplankton: fitness, foraging and predation
TLDR
It is shown that a convoluted swimming path in the form of meanders, zigzags or spirals confers greater fitness than swimming along a straight path.
Time-Frequency Analysis Reveals Pairwise Interactions in Insect Swarms.
TLDR
Using multicamera imaging and tracking, it is shown that the midge behavior can be segmented into two distinct modes: one that is independent and composed of low-frequency maneuvers, and one that consists of higher-frequency nearly harmonic oscillations conducted in synchrony with another midge.
Flow disturbances generated by feeding and swimming zooplankton
TLDR
The fluid disturbances produced by feeding and swimming in zooplankton with diverse propulsion mechanisms and ranging from 10-µm flagellates to greater than millimeter-sized copepods are described by means of particle image velocimetry.
Zooplankton can actively adjust their motility to turbulent flow
TLDR
The study reveals an active adaptation that carries strong fitness advantages and provides a realistic model of plankton motion in turbulence that shows excellent quantitative agreement with the authors' measurements when turbulence is significant.
Hypothesis for origin of planktonic patchiness
TLDR
Nonlinear analysis of biological interactions between phytoplankton and herbivorous copepods and the final stages of pattern formation provides insights into the spatial scale of patterns which might arise in this way.
