3.step 1.step one Sepangar shore

All in all, 850 specimens was indeed obtained spanning of 5 variety belonging to one or two genera regarding family unit members Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and D. tumidus. The largest variety try C. striolatus (SL 5.64 ± 2.55 mm), with C. merguiensis (5.45 ± 2.forty-eight mm), D. pallescens (cuatro.37 ± dos.39 mm), D. klaasi (cuatro.twenty eight ± dos.37 mm) and you will D. tumidus (4.fourteen ± step 1.86 mm). The best assortment try filed in the 100 m (H? = step one.09) while the low in the 0 m (H? = 0.00) where only 1 kinds (D. klaasi) are establish. Hermit crab kinds during the a hundred yards was indeed the essential uniformly marketed (J? = 0.79) as they have been the least uniformly distributed within 0 m (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.

Imply thickness (+SD) from hermit crabs of the species during the an (e-f) beaches. D. pallescens of Sepangar was not integrated because of very low occurrence and you may are missing in most stations.

3.step 1.dos Sulaman coast

There had been merely several species at the Sulaman coastline; brand new dominating D. foresti (SL 2.83 ± step one.03 mm) and one Diogenes sp. (Contour 3b) which was too little (SL step one.53 ± 0.42 mm) become fully known. Range and you may evenness indices just weren't determined getting hermit crabs into the Sulaman because of a low number of species. Density out of D. foresti generally reduced away from step three.33 ± dos.65 ind/meters dos at 0 m to help you 0.16 ± 0.twenty eight ind/m 2 within 29 meters (Shape 2e). Diogenes sp. is absent within 29 m and you can took place few having an overall total suggest thickness away from 0.21 ± 0.32 ind/m dos . Chi-rectangular test found no association (? dos = 0.fifteen, df = dos, p > 0.05) anywhere between hermit crab species and station in the Sulaman coast.

3.dos Cover explore

On Sepangar coast, a total of 30 shell varieties were utilized from the hermit crabs with most occupied shells becoming Clypeomorus batillariaeformis (%) followed closely by C. bifasciata (8.61%) and you can Rhinoclavis sinensis (4.13%) when you find yourself use of other type of shells was indeed markedly reduced (Dining table step three). Shells utilized by hermit crabs from the route 5 looked like the absolute most varied (H? = 1.29, J? = 0.51) one of most of the channels whereas channel dos is actually minimum of diverse (H? = 0.66, J? = 0.30) (Desk 4). The brand new constitution out of hermit crabs based on the four very occupied shells was revealed inside Shape 4. The shell group ‘others' signifies the collective ratio off hermit crabs of the varieties one used the left 26 shell versions. Brand new blank shells away from C. batillariaeformis comprised many shells used by most of the hermit crab variety whereas shells out of C. bifasciata represented reasonable proportion regarding shells utilized by C. striolatus (17%), D. tumidus (11%) and you can D. klaasi (6%) (Contour cuatro). On Sulaman coastline, merely a few shells were used from the hermit crabs: Nassarius livescens and you will Cerithidea cingulata on second filled by 98% of hermit crabs (Table step three).
