5.0 Benthic and Epibenthic Invertebrates 5.2.3 Data Analysis Infauna data were entered into a database from the taxonomic laboratory sheets. Macroinvertebrate data were coded from the field data sheets and entered into a separate database. Data were subjected to quality assurance review. Infaunal data from box core and Van Veen samples were standardized to number per 0.1 m 2 for comparison with each other and historical data. Abundance and biomass of the trawl collected invertebrates is presented as catch per unit effort (CPUE), which represents the number of individuals captured standardized to the amount of the effort (total time or area sampled) exerted. Averages were calculated for each station across surveys and for the total mean for all stations and surveys combined. Diversity was calculated with three different indices, which are derived measures based upon the number of species (species richness) and their abundances (equitability). The Shannon- Wiener diversity index tends to emphasize the equitability of the species distribution in a community. The Margalex Index incorporates the number of species and total number of individuals. The Dominance Index computes the number of species that account for 75% of the total abundance. Cluster analysis was performed for the infauna data for both the winter and summer surveys. This analysis was used to identify groups of stations that were biologically similar. Species composition and relative abundance of the species defined the groups. Rare species (i.e., occurring at fewer than three stations) were excluded from the analysis. Figures of station and species dendrograms were prepared from the cluster analysis. 5.3 INFAUNA This section presents discussions of community summary measures (Section 5.3.1), a detailed description and evaluation of species composition (Section 5.3.2) and dominant species (Section 5.3.3), summary of spatial and temporal patterns (Section 5.3.4), and a comparison of the 2008 Biological Survey results with historical studies (Section 5.3.5). The box core and Van Veen comparison is discussed in Section 5.3.6. Raw summary data and a complete listing of abundance by species and stations and of biomass data are provided in Appendix E. 5.3.1 Community Summary Measures 5.3.1.1 Abundance A total of 10,772 infaunal invertebrates weighing 704 grams and comprising 258 species was collected across the 29 stations (Table 5.3-1). Total infaunal abundance was nearly double during the summer (7,017) compared to winter (3,755) surveys. Mean abundances ranged from 80 to 488 individuals/0.1 m 2 (Table 5.3-1). Abundance varied with depth and location in the harbors. Abundances were similar between the inner harbor stations (80-488 individuals/0.1 m 2 ) and outer harbor stations (93-413 individuals/0.1 m 2 ), but were markedly higher in shallow water (126-488 individuals/0.1 m 2 ) than in deep water (80-289 individuals/0.1 m 2 ). In the outer harbor, mean abundance in shallow water was nearly two times higher (mean of 249 individuals/0.1 m 2 ) compared to deep water (mean of 142 individuals/0.1 m 2 , Table 5.3-1). In the inner harbor, mean abundance at the shallow water station (488 individuals/0.1 m 2 ) was approximately 3 times greater than at deepwater stations (173 individuals/0.1 m 2 ). The highest mean abundances (mean > 400 individuals/0.1 m 2 ) were found at the Pier 300 Shallow Water Habitat and Consolidated Slip of inner Los Angeles Harbor (Stations LA7 and 2008 Biological Surveys of Los Angeles and Long Beach Harbors 5–3 April 2010
5.0 Benthic and Epibenthic Invertebrates LA14). The lowest mean abundances (20 g/0.1 m 2 ) were in Los Angeles outer harbor (Station LA13), Long Beach Shallow Water Habitat (Station LB2), and outer Long Beach Harbor (Station LB9). The lowest ( 35 unique species) were located at the Pier 300 Shallow Water Habitat (Station LA7), the channel between Piers 300 and 400 (Station LA9), the deepwater outer harbor (Station LB9), the main channel of Los Angeles Harbor (Station LA4), Long Beach Shallow Water Habitat (Station LB2), and Long Beach deep outer harbor (Station LB7). The fewest mean numbers of species (< 25 species) were found at the Cabrillo Marina (Station LA12), Los Angeles West Basin (Station LA5), Seaplane Anchorage (Station LA8), Consolidated Slip of inner Los Angeles Harbor (Station LA14), Long Beach inner harbor (Station LB14), and Slip 1 of the East Basin in Long Beach Harbor (Station LB12). 5.3.1.4 Diversity and Dominance Shannon-Wiener diversity, which considers the equitability of abundance among species, was highest at stations in the channel between Piers 300 and 400 (Station LA9), Long Beach outer harbor (Station LB9), and Long Beach deep outer harbor (Station LB7) (Table 5.3-1). The Margalef Index, which considers the total number of individuals in all species, was highest at these stations, as well. Three stations had relatively high Shannon-Wiener diversity (Stations LA4 and LB5) or Margalef Index (Station LA6), but moderate numbers of species. Dominance values generally were highest at stations with the highest species diversity and generally lower where diversity values were less (Table 5.3-1). Stations where 19 or more species accounted for 75% of the abundance were in Long Beach and Los Angeles outer harbor (Stations LB7, LB9, LA11). Station LA11 in outer Los Angeles Harbor also had relatively high dominance, but had moderate numbers of species and diversity. Species diversity (Shannon-Wiener and Margalef) and dominance generally were lowest at the stations with the fewest number of species; i.e., Cabrillo Marina (Station LA12), Consolidated Slip of inner Los Angeles Harbor (Station LA14), and Seaplane Anchorage (Station LA8). Dominance also was relatively low in the Turning Basin of inner Los Angeles Harbor (Station LA15). 5–4 2008 Biological Surveys of Los Angeles and Long Beach Harbors April 2010
