3.1.step 1 Sepangar coastline

A total of 850 specimens was indeed amassed spanning of 5 flingster sign up species owned by a few genera regarding the family unit members Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you may D. tumidus. The greatest species are C. striolatus (SL 5.64 ± dos.55 mm), followed by C. merguiensis (5.forty five ± dos.forty-eight mm), D. pallescens (4.37 ± 2.39 mm), D. klaasi (4.twenty eight ± dos.37 mm) and you may D. tumidus (cuatro.14 ± step 1.86 mm). Best range is actually submitted during the a hundred yards (H? = 1.09) just like the lowest at the 0 m (H? = 0.00) in which singular species (D. klaasi) are present. Hermit crab varieties in the 100 m was in fact the absolute most equally distributed (J? = 0.79) as they was in fact the least uniformly delivered within 0 m (J? = 0.00) (Table 2).

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.

Suggest occurrence (+SD) away from hermit crabs by the species from the an (e-f) coastlines. D. pallescens from Sepangar wasn’t incorporated because of low occurrence and you may is actually missing for the majority stations.

step three.1.dos Sulaman shore

There had been just two species during the Sulaman shore; the new prominent D. foresti (SL 2.83 ± step one.03 mm) plus one Diogenes sp. (Profile 3b) that was too small (SL step 1.53 ± 0.42 mm) to be totally understood. Assortment and you may evenness indicator weren’t determined having hermit crabs into the Sulaman because of a decreased amount of types. Thickness off D. foresti generally decreased out of step three.33 ± 2.65 ind/yards dos in the 0 yards so you can 0.sixteen ± 0.twenty-eight ind/m dos during the 30 yards (Profile 2e). Diogenes sp. is actually absent at 31 m and you can took place few with an overall total indicate density out-of 0.21 ± 0.thirty two ind/meters 2 . Chi-rectangular attempt shown zero organization (? dos = 0.fifteen, df = dos, p > 0.05) ranging from hermit crab varieties and route from inside the Sulaman coast.

step 3.2 Cover explore

In the Sepangar coast, all in all, 31 cover variety were utilized by the hermit crabs with most filled shells getting Clypeomorus batillariaeformis (%) followed closely by C. bifasciata (8.61%) and you can Rhinoclavis sinensis (cuatro.13%) when you find yourself usage of different kind away from shells was indeed markedly reasonable (Table step three). Shells used by hermit crabs in the channel 5 appeared as if more varied (H? = step 1.30, J? = 0.51) certainly one of all station while station 2 is actually the least diverse (H? = 0.66, J? = 0.30) (Table cuatro). The structure out-of hermit crabs according to the five really filled shells is found when you look at the Figure 4. New shell classification ‘others’ represents this new cumulative ratio away from hermit crabs by the species that used the left twenty-six layer sizes. The blank shells out-of C. batillariaeformis comprised most shells utilized by all of the hermit crab variety whereas shells out of C. bifasciata depicted generous proportion regarding shells used by C. striolatus (17%), D. tumidus (11%) and you can D. klaasi (6%) (Figure 4). During the Sulaman shore, just two shells were utilized of the hermit crabs: Nassarius livescens and Cerithidea cingulata toward latter filled of the 98% of your own hermit crabs (Dining table step 3).
