Following the invisible trail: kinematic analysis of mate-tracking in the copepod Temora longicornis.
We have analysed the fine-scale kinematics of movement of male and female copepods, Temora longicornis, to resolve how these small animals find their mates. Location of the trail initially involves rapid random turning and high rates of directional change. Males subsequently increase their rate of movement as they follow the trail, and execute a regular pattern of counter turns in both x,z and ...
متن کاملLocating a mate in 3D: the case of Temora longicornis
Using laser optics to illuminate high-resolution video-recordings, we revealed behavioural mechanisms through which males of the calanoid copepod speciesTemora longicornis locate females. Males ofT. longicornis swam at signi¢cantly faster speeds than females along more sinuous routes, possibly re£ecting adaptations to increase encounter with females. Upon approaching within 2mm (i.e. two body l...
متن کاملDynamics of gut pigment in the copepod Temora longicornis and the determination of in situ grazing rates
Gut fluorescence attributable to algae caten by an herbivorous zooplankter should be a function of chlorophyll consumption minus loss of pheopigments in defecation. The amount of chlorophyll ingested, as determined in a laboratory grazing experiment, minus the gut pigment content at the end in the grazers, should equal chlorophyll dcfecatcd and should also provide a calibration for the determin...
متن کاملPredation effects of the calanoid copepod
This study investigated feeding rates and selective feeding of the common copepod Acartia tonsa on mixtures of the heterotrophic dinoflagellate Protoperidinium cf. divergens and the cooccurring red-tide dinoflagellate Gonyaulax polyedra and predation effects of A. tonsa on the population growth of P cf. divergens during simulated red-tide and non-red-tide periods. Ingestion and clearance rates ...
