104 JOURNAL OF THE HELMINTHOLOGICAL SOCIETY OF WASHINGTON, 66(2), JULY 1999 gust-November (2.2 ± 0.94, 0-41), respectively, and least abundant in May-August (nongravid: 0.09 ± 0.09, 0-4; gravid: 0.1 ± 0.08, 0-3) (Fig. 2b). Camallanus oxycephalus was most prevalent and abundant in May-August (36%) (0.7 ± 0.26, 0-11). Prevalence and abundance declined throughout the year and were lowest in February-May (10%) (0.1 ± 0.05, 0-2), (x2 = 12.888, P < 0.05) (ANOVA, P < 0.01), respectively (Table 1, Fig. 3). Prevalence of L. thecatus did not change seasonally (x2 = 5.278, P > 0.05) (Table 1), but its abundance did vary among time periods and peaked in May-August (0.6 ± 0.19, 0-5) (ANOVA, P < 0.05) (Fig. 3). Crepidostomum cornutum, S. carolini, and N. cylindratus were uncommon (prevalence of each, < 7%), and too few individuals (abundance of each, < 0.1) were recovered to determine seasonal patterns of prevalence and abundance (Table 1). Parasite abundance (overall: 8.2 ± 0.8, 0—56) differed significantly among time periods (AN- COVA, P < 0.05). Abundance was lowest in May-August (4.0 ± 0.87, 0-26), increased during August-November (7.3 ± 1.66, 0-53) and November-February (8.5 ± 1.54, 0-45), and reached its highest value during February-May (12.8 ± 1.81, 0-56). Infracommunity analysis Overall, host body size was correlated with infracommunity diversity (r = 0.18, P < 0.05), but this relationship was not significant within time periods. The most diverse infracommunity was found in November-February (1.294 ± 0.197, 0.0-4.14), whereas in February-May, infracommunity diversity was lowest (0.689 ± 0.136, 0.0—3.35). The remaining 2 time periods, May—August and August-November, showed intermediate levels of infracommunity diversity (0.889 ± 0.151, 0.0-3.40 and 0.959 ± 0.185, 0.0-4.01, respectively). However, infracommunity diversity did not differ significantly among time periods (ANCOVA, P > 0.05). Overall infracommunity diversity was 0.963 ± 0.087 (0.0- 4.14). Both overall and within time periods, host body size did not influence infracommunity species richness. Helminth richness was lowest in May-August (1.244 ± 0.143, 0-4) and increased in August—November (1.302 ± 0.139, 0-3) and November-February (1.353 ± 0.096, 0-3). Infracommunity richness was greatest in February-May (1.549 ± 0.113, 0-3). However, infracommunity species richness did not differ significantly among time periods (ANOVA, P > 0.05). Overall infracommunity species richness was 1.365 ± 0.062 (0-4). Infracommunity predictability differed significantly among time periods (ANOVA, P < 0.001). Infracommunity similarity was greatest in February-May (0.56 ± 0.01, 0-1) and lowest in May-August (0.22 ± 0.01, 0-1). In August-November and November-February, infracommunity similarity values were intermediate (0.31 ± 0.01, 0-1 and 0.34 ± 0.01, 0-1, respectively). Overall infracommunity similarity was low (0.31 ± 0.003, 0-1). Component community analysis The trematodes B. cupuloris and Genarchella sp. were the most prevalent and abundant helminths and dominated the component community of Lepomis miniatus (Table 1). Barbulostomum cupuloris was most prevalent (50%), and although Genarchella sp. was recovered from fewer hosts (35%), its overall abundance (3.9 ± 0.64, 0-43) did not differ significantly from that of B. cupuloris (3.5 ± 0.46, 0-37) (Mest, P > 0.05). Although together these 2 trematodes accounted for 1,485 of the total 1,662 worms recovered during this study (89%), no significant association was found between them with respect to concurrent patterns of infection (x2 = 0.032, P > 0.05). The nematode C. oxycephalus was recovered from 24% of hosts examined, but its abundance was low (0.4 ± 0.08, 0-11). The remaining 4 helminth species showed low prevalence and abundance and, together with C. oxycephalus, represented only 11 % of the total helminth specimens recovered (Table 1). Component community diversity was low (0.47). It was greatest in February-May (1.16), progressively declined through May-August (0.63) and August-November (0.45), and was lowest in November-February (0.34). Component community species richness changed slightly over the year. Six helminth species were recovered during May—August, August—November, and November-February, whereas 7 helminth species were found in February-May (Table 1). The trematode C. cornutum and the acanthocephalan TV. cylindratus were the only helminths not found in all 4 time periods (Table 1).
