Espèce Pleuromamma quadrungulata - Carte de distribution 3issued from : M. Saraswathy in Mahasagar-Bull. Nat. Inst. Oceanogr., 1986, 19 (3). [p.191, Fig.2D].
Distribution of P. quadrungulata in the Indian Ocean (in the upper water column of 200 m).
Triangle: South West Moonsoon season: April 16 to October 15 (white triangle = negative stations; black = animals collected). Circle: North East Moonsoon season: October 16 to April 15 (white circle = negative stations; black = numbers of ianimals collected).
Nota: Mainly distributed between 10°N and 10°S. Vey rare species found during the SW moonsoon season.
Espèce Pleuromamma quadrungulata - Carte de distribution 4issued from : G.A. Rebstock in Global change Biology, 2002, 8. [p.77, Fig.2 c].
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.
