a b Figure 2. Mean numbers of holoplankton (a) and meroplankton (b) in each station on each day of sampling. Stations: 1 - Ferraz; 2 - Botany Point; 3 - Machu Pichu; 4 - Point Thomas; 5 - Arctowski. 108 | Annual Activity Report 2011
sampled period, except for station 4 on 12/15/2009 and station 5 on 12/29/2009, whose averages were higher. The mean numbers of meroplankton are shown in Figure 2B. Meroplankton density was high in Machu Picchu station (St. #3) in the days 11, 23 and 29 December 2009. On 12/15/2009 was observed the lowest average abundance in almost all stations during the sampling period. Echinodermata and Polychaete larvae were the first and second most abundant meroplankton, respectively. The differences observed in the ANOVA resulting from the comparison of the densities (organisms.100m -3 ) between stations and dates were significant (df = 19; F = 2535; p < 0.05) and caused mainly by the amount of organisms in station 4 in 12/15/2009 and 5 in 12/29/2009. The differences between the abundances of meroplankton in the stations and dates were significantly different (ANOVA df = 17; F = 2.57; p < 0.05). Mean water temperature during the sampling period ranged from –0.13 to –0.59 °C. Average salinity ranged from 33.16 to 34.32, water transparency ranged from 1.80 to 10.50 m, pH from 7.85 to 8.07, dissolved oxygen ranged from 6.46 to 7.56 mL L –1 , phosphate from 1.29 to 2.08 μmol L –1 , silicate from 40.53 to 42.63 μmol L –1 , nitrite from 0.02 to 0.17 μmol L –1 and nitrate from 12.94 to 19.69 μmol L –1 . PCA of holoplankton, meroplankton and environmental parameters are shown in Figure 3. The first two components of PCA analyses explain 49.27% of the total variance. Holoplankton abundance is influenced by waters with higher DO and phosphate and less silicate, nitrite, nitrate under lower pH, wind gust and speed in less turbid waters. The second factor indicated that environmental conditions favored meroplankton abundance in waters with higher temperature, DO, pH, nitrite, less phosphate, silicate under low wind gust in more turbid waters. While holoplankton had a high correlation with Factor 1 meroplankton had correlation with Factor 2 and no correlation to each other. Figure 3.
