3.step one.step one Sepangar coast
A total of 850 specimens have been collected comprising https://datingranking.net/tr/planetromeo-inceleme/ of five varieties owned by two genera regarding nearest and dearest Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you may D. tumidus. The greatest varieties was C. striolatus (SL 5.64 ± 2.55 mm), followed by C. merguiensis (5.forty-five ± dos.forty eight mm), D. pallescens (cuatro.37 ± 2.39 mm), D. klaasi (4.twenty-eight ± 2.37 mm) and you may D. tumidus (cuatro.14 ± step one.86 mm). The most effective variety try filed within one hundred meters (H? = step one.09) due to the fact lowest during the 0 yards (H? = 0.00) in which singular kinds (D. klaasi) was introduce. Hermit crab variety at the one hundred meters have been one particular uniformly distributed (J? = 0.79) as they was minimum of equally marketed at the 0 yards (J? = 0.00) (Table dos).
The overall highest density was reported for D. tumidus (8.98 ± 6.52 ind/m 2 ) which peaked at 50 m ( ± ind/m 2 ) but absent at 0 m (Figure 2a). This species was dominant at both 50 and 75 m stations (Figure 3a). Density of D. tumidus decreased gradually towards 100 m. On the other hand, D. klaasi was present in the first three stations (0, 25 and 50 m) and absent at 75 and 100 m. It was the sole species at 0 m with density of 6.25 ± 7.39 ind/m 2 . Peak density of this species was observed at 25 m ( ± ind/m 2 ) (Figure 2b). Densities of both Clibanarius species generally increased towards the sea. At the highest station (0 m), C. striolatus was absent but gradually increased in density from 25 m (0.22 ± 0.54 ind/m 2 ) to 100 m (5.33 ± 8.92 ind/m 2 ) (Figure 2c). Similarly, C. merguiensis was absent at 0 m but had density peak at 100 m (6.11 ± 7.20 ind/m 2 ). Lowest density of this species was recorded at 75 m (1.17 ± 2.07 ind/m 2 ) (Figure 2d). The results from ANOVA showed no significant difference (p > 0.05) in density among stations for all species. The least abundant species in the study was D. pallescens which was present at 50 m (0.11 ± 0.17 ind/m 2 ) and 100 m (0.11 ± 0.27 ind/m 2 ). Chi-square test revealed strong dependency/association (? 2 = , df = 16, p < 0.0001) of hermit crab species on stations/zones in Sepangar shore.
Mean density (+SD) from hermit crabs because of the variety from the an (e-f) beaches. D. pallescens off Sepangar wasn’t incorporated due to really low occurrence and you can is absent in most stations.
3.step one.2 Sulaman shore
There are only a couple of kinds at the Sulaman coast; the brand new dominating D. foresti (SL 2.83 ± step one.03 mm) and something Diogenes sp. (Contour 3b) that was too little (SL 1.53 ± 0.42 mm) to be totally identified. Assortment and evenness indices were not computed to own hermit crabs for the Sulaman on account of the lowest amount of species. Occurrence from D. foresti basically decreased off step three.33 ± dos.65 ind/meters 2 within 0 yards to help you 0.sixteen ± 0.twenty-eight ind/yards dos at the 31 m (Figure 2e). Diogenes sp. was absent during the 29 yards and you will occurred in small number that have a total indicate occurrence out-of 0.21 ± 0.thirty two ind/yards dos . Chi-rectangular shot found no organization (? 2 = 0.fifteen, df = 2, p > 0.05) anywhere between hermit crab varieties and you may station within the Sulaman coastline.
step three.dos Cover explore
In the Sepangar coastline, all in all, 31 layer varieties were used because of the hermit crabs with most filled shells are Clypeomorus batillariaeformis (%) accompanied by C. bifasciata (8.61%) and you may Rhinoclavis sinensis (4.13%) whenever you are utilization of other type away from shells was indeed markedly low (Table step three). Shells employed by hermit crabs from the route 5 appeared to be more varied (H? = step one.29, J? = 0.51) among most of the station while route 2 are minimum of varied (H? = 0.66, J? = 0.30) (Desk cuatro). New constitution out of hermit crabs in accordance with the four very filled shells are found within the Profile cuatro. The latest shell category ‘others’ stands for the fresh collective proportion out of hermit crabs from the types that used the remaining twenty six layer versions. New blank shells from C. batillariaeformis constructed the majority of shells employed by all of the hermit crab variety while shells off C. bifasciata represented good proportion out of shells employed by C. striolatus (17%), D. tumidus (11%) and you may D. klaasi (6%) (Shape cuatro). Within Sulaman shore, merely a couple of shells were used because of the hermit crabs: Nassarius livescens and Cerithidea cingulata with the second occupied from the 98% of hermit crabs (Table step three).
