GSI regarding each other sexes increased off April to help you Summer, peaked during the Summer, and you may steadily rejected regarding summer and you may slide
Calico phase individuals were observed at both transect sites throughout the study period (Figure 4). OS phase males were observed at both transect sites from , where they increased in frequency over this period (Figure 4). Monthly variations in the proportion of OS phase individuals observed on transects were significantly different than expected at random for both the Intake Pipes site (Pearson chi-square goodness of fit, [chi square] = , df = 7, P < 0.01) and the Pumpernickel Cove site (Pearson chi-square goodness of fit, [chi square] = , df = 7, P < 0.01).
The second included somebody thought to intimately younger
Mean monthly GSI of males (Figure 3) and females (Figure 5) remained low from January to April. GSI values of males and females were lowest in February and December. Monthly variations in male GSI (Kruskal-Wallis, KW = , df = 8, P < 0.01) and female GSI (Kruskal-Wallis, KW = , df = 8, P < 0.01) were significant. Males and females containing visibly ripe gonadal tissue were collected from May to October, and over 93% of adults collected from June to August were visibly ripe. Females with hydrated ovaries were collected from June through September, and the highest frequency of hydrated females occurred in July (Figure 5). The mean GSI of females with hydrated ovaries (5.79%) was significantly higher than the mean GSI of non-hydrated, ripe females (3.56%; unpaired t test, t = 7.78, df = 229, p < 0.01).
Os phase citizens were expose all the time and on a beneficial regular basis in industry observations used out of , and also in the latest captive examination of 2002. Operating system phase individuals were not present in field findings conducted in the later . Given that zero significant difference was based in the month-to-month frequency of the fresh new Os stage certainly people obtained off (Pearson chi-square god away from match, [chi square] = 1.19, df = 2, P = 0.55), investigation out-of every men accumulated away from during this period were pooled for further research. Throughout that months, Operating system phase people had been collected right through the day and exhibited no tall variations in regularity according to the time period seized (Pearson chi-square goodness away from complement, [chi-square] = step 1.thirty six, df = dos, p = 0.51). Moreover, brand new volume off Operating-system phase men failed to differ rather certainly one of the fresh five number one stages of one’s lunar years (Pearson chi-square, [chi square] = 4.45, df = step 3, P = 0.22).
