step 3.1 Assortment and you may variety of your own hermit crab community

step 3.1.step 1 Sepangar shore

A total of 850 specimens was indeed obtained spanning of 5 variety owned by a couple of genera regarding the family relations Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you will D. tumidus. The most significant varieties was C. striolatus (SL 5.64 ± dos.55 mm), with thaicupid platinum satın al C. merguiensis (5.forty five ± dos.48 mm), D. pallescens (4.37 ± dos.39 mm), D. klaasi (4.28 ± 2.37 mm) and you will D. tumidus (4.14 ± step one.86 mm). The best diversity is submitted within a hundred meters (H? = 1.09) given that reasonable during the 0 m (H? = 0.00) in which only one varieties (D. klaasi) try establish. Hermit crab species at 100 m had been the absolute most uniformly delivered (J? = 0.79) because they was indeed minimum of equally marketed within 0 meters (J? = 0.00) (Desk 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 density (+SD) regarding hermit crabs by the species from the an (e-f) shores. D. pallescens out-of Sepangar wasn’t provided on account of very low occurrence and you will is absent for the majority stations.

3.step 1.2 Sulaman coast

There have been merely two species within Sulaman coast; the brand new dominant D. foresti (SL dos.83 ± step 1.03 mm) and something Diogenes sp. (Figure 3b) which was too tiny (SL step one.53 ± 0.42 mm) to be fully identified. Assortment and you can evenness indicator weren’t determined for hermit crabs when you look at the Sulaman because of the lowest level of types. Density of D. foresti basically diminished out of step three.33 ± 2.65 ind/yards dos at the 0 meters in order to 0.16 ± 0.twenty eight ind/meters 2 during the 30 m (Contour 2e). Diogenes sp. is missing in the 30 m and you may occurred in few that have a total indicate occurrence regarding 0.21 ± 0.32 ind/meters 2 . Chi-rectangular decide to try shown no relationship (? dos = 0.15, df = 2, p > 0.05) ranging from hermit crab types and you may station during the Sulaman coast.

step three.2 Shell fool around with

During the Sepangar coastline, a total of 30 shell types were used by hermit crabs with a lot of occupied shells being Clypeomorus batillariaeformis (%) accompanied by C. bifasciata (8.61%) and you can Rhinoclavis sinensis (4.13%) when you are utilization of other type off shells were markedly reasonable (Dining table 3). Shells utilized by hermit crabs during the channel 5 looked like probably the most diverse (H? = 1.29, J? = 0.51) certainly one of most of the stations whereas station dos was at least varied (H? = 0.66, J? = 0.30) (Dining table cuatro). The latest structure off hermit crabs based on the five most filled shells is revealed from inside the Profile 4. This new layer classification ‘others’ represents new collective proportion from hermit crabs because of the species one to utilized the remaining twenty-six layer types. Brand new blank shells out-of C. batillariaeformis made-up more shells employed by all of the hermit crab variety while shells out of C. bifasciata illustrated big ratio from shells used by C. striolatus (17%), D. tumidus (11%) and D. klaasi (6%) (Shape 4). During the Sulaman coastline, just a couple of shells were used of the hermit crabs: Nassarius livescens and you can Cerithidea cingulata towards second occupied because of the 98% of hermit crabs (Desk step three).
