Climatic regime shifts and decadal-scale variability in calanoid copepod populations off southern California (31°-35°N, 117°-122°W.
Cumulative sums of nonseasonal anomalies from the long-term means of copepod abundance from years 1950 to 2000.
A negative slope indicates a period of below-average anomalies; a positive slope indicates a period of above-average anomalies. Abrupt changes in slope indicate step changes. Step changes are marked with arrow (downward -pointing for decreases).
The October 1966 cruise (prior to the increase in sampling depth), March 1976 cruise (prior to the 1976-77 climatic regime shift), and October 1988 cruise (prior to the hypothesized 1989 climatic regime shift) are marked with vertical lines. |
 Issued from : M.R. Landry in Limnol. Oceanogr., 1978, 23 (6). [p.1106, Fig.1].Feeding of Labidocera female on an Artemia nauplius (N) showing typical orientation of the prey az it is detected (A) and in position to be captured (B).
Nauplius is entrained in copepod's swimming and is accelerating toward predator. Copepod is also accelerating toward prey.
Photographs were recreated from a feeding sequence filmed at 50 frames per second using hokographic techniques (see Stewart & al., 1973). Time interval is 0.10 s.
Nota: Animals captured by subsurface net tows (about 5 m) from the coastal waters off La Jolla (California), 1 or 2 days before being used in feeding experiments.from nearshore southern California) |
