1 Long term changes in zooplankton size distribution in the Peruvian Humboldt Current System: Conditions favouring sardine or anchovy Patricia Ayón 1, Gordon Swartzman 2 Pepe Espinoza 1, Arnaud Bertrand 1,3 1 Instituto del Mar del Perú (IMARPE) 2 University of Washington 3 Institut de recherche pour le développement (IRD)
2 MAIN UPWELLING SYSTEMS GREELAND NORTH AMERICA EUROPE ASIA H H California Current Humboldt Current SOUTH AMERICA Canary Current Benguela Current AFRICA AUSTRALIA H H Major upwelling H Area of high pressure Direction of ocean current
3 Pacific sardine Sardinops sagax Peruvian anchovy Engraulis ringens
4 Trend of Mean Biomass of Peruvian ANCHOVY and SARDINE (Northern - Central stock) Peruvian anchovy Pacific sardine Source: Guevara-Carrasco
5 Hypotheses to explain alternation Source F.Chavez Source R. Guevara-Carrasco
6 Hypotheses to explain sardine-anchovy alternation Size-selective feeding hypothesis Optimal growth temperature Avoidance of low oxygen waters (upwelling) by sardine (habitat change)
7 A few relevant facts Sardine distribution farther offshore than anchovy Sardine predominate during warmer periods (El Niño, El Viejo), anchovy during colder (higher upwelling) periods (La Niña, La Vieja) Anchovy are more associated with cold coastal waters, sardine with offshore oceanic waters
8 Size feeding hypothesis argument and support Both can filter feed, but sardine can filter feed energetically more efficiently and can take smaller organisms (up to 1 mm) Anchovy are mostly bite feeders and larger prey provide more nutrients More upwelling more nutrients larger phytoplankton larger zooplankton favor anchovy Less upwelling scarce nutrients smaller phytoplankton smaller zooplankton favor sardine
9 Examine size-feeding hypothesis Use zooplankton samples (formaldehyde stored) from 121 surveys (> 15,000 samples) latitude S Jose Olaya SNP longitude W
10 Zooplankton Sampling Hensen nets, 300-um mesh 0-50 m vertical haul Remove gelatinous zooplankton and ichthyoplankton Zooplankton dominated by copepods and euphausiids Determined biovolume at time of sample
11 Qualitative sampling Classify organisms by size: small, medium, large zooplankton, euphausiids In each sample classify dominance of each size groups by integer between 0 and 3 (0=absent) Dominance is independent of biovolume (supposedly!) small medium large euphausiids
12 Zooplankton analysis 1. Validation Comparison with two data sets: A) Species enumerations for 2 surveys in 1996 and 1998 (species compositionabundance) B) Size distribution from Zooscan on 2 surveys in 1965 and 1967 (32 samples) small <1.3mm medium mm large > 2.9mm euphausiids 10-25mm
13 Zooplankton analysis 1. Validation- correlation (r) Data Small zooplankton (< 1.3 mm) Medium zooplankton ( mm) Large zooplankton (>2.9 mm)* Euphausiids (10-25 mm)* 1996,1998 species composition 0.22 (p =0.027) 0.33 (p=0.0014) 0.24 (p=0.016) (p=5x10-7 ) A 1965, 1967 Zooscan size composition (p=0.013) (P=0.0019) (0.0205) (4.3 x10-7 ) B
14 Zooplankton analysis - GAM Generalized Additive Models Nonparametric regression uses smooths instead of least square fits (not linear) Effect of covariates Sea surface temperature (SST), surface salinity (SSS), latitude (lat), year, month (mo), time of day (time) and distance from 200-m isobath (dist200; determines on-off shelf location)
15 Zooplankton analysis GAM- small zooplankton significant covariates SSS effect SSW year effect Abundance of small zooplankton along time SSS year month effect Seasonality of small zooplankton month
16 Zooplankton analysis GAM euphausiids Abundance of euphausiid along time on-off shelf effect year effect distance from 200-m isobath year diel effect time of day
17 Zooplankton analysis relationship to anchovy and sardine abundance biomass (mt) anchovy sardine year size group dominance euphausiids small zooplankton year
18 Zooplankton size fish time series Examine temporal pattern of size classes of zooplankton in relation to sardine and anchovy biomass time series: Cross correlation analysis at different time lags (i.e. years)
19 Zooplankton size fish time series cross correlation analysis A anchovyeuphausiids cross correlation A B sardinesmall zooplankton Cross correlation B lag yrs lag yrs
20 Cross correlation interpretation Anchovy in phase with euphausiids Sardine in phase with small zooplankton Other size groups not in phase with either This supports the size-feeding hypothesis for both anchovy and sardine
