| 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 y,z planes to stay near or within the central axis of the odour field. pursuit behaviour of males is st ... | 1998 | 9652125 |
| microassays for a set of enzymes in individual small marine copepods. | fluorogenic assays for a set of five hydrolytic enzymes involved in digestion and food utilization (alanine and arginine aminopeptidase, lipase/esterase, chitobiase, and beta-glucosidase) were optimized to measure activities of these enzymes in the same extracts of individual small north sea copepods. the enzyme activities of acartia clausi, centropages typicus, corycaeus anglicus, paracalanus parvus, and temora longicornis showed distinct species specific activity patterns, but also high intra- ... | 2006 | 16978893 |
| on the morphology and life-history of hemiurus luehei odhner, 1905 (digenea: hemiuridae). | previously undescribed cystophorous cercariae which develop in sporocyst germinal sacs in the tectibranch opisthobranch philine denticulata (adams) are shown to be cercariae of hemiurus luehei odhner, 1905 (hemiuridae), a common stomach parasite of clupeid and salmonid fishes off the atlantic coast of europe, in the baltic and the mediterranean sea. the free-swimming cercariae are seized by calanoid copepods. temora longicornis (müller) and acartia tonsa dana acted as suitable experimental inter ... | 1990 | 2230028 |
