step three.step 1.step 1 Sepangar coast

All in all, 850 specimens was basically built-up comprising of 5 species owned by one or two genera on the nearest and dearest Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you will D. tumidus. The largest varieties is C. striolatus (SL 5.64 ± dos.55 mm), accompanied by C. merguiensis (5.45 ± 2.48 mm), D. pallescens (4.37 ± 2.39 mm), D. klaasi (4.28 ± 2.37 mm) and you will D. tumidus (4.fourteen ± step 1.86 mm). The best diversity was recorded on 100 yards (H? = step 1.09) just like the lowest within 0 yards (H? = 0.00) in which one variety (D. klaasi) is establish. Hermit crab types within 100 meters was the quintessential uniformly pink cupid Fiyat marketed (J? = 0.79) as they have been minimum of evenly distributed from the 0 meters (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 occurrence (+SD) out-of hermit crabs because of the types on a keen (e-f) beaches. D. pallescens of Sepangar wasn’t integrated because of very low thickness and you may is actually absent in most programs.

step 3.step 1.2 Sulaman coast

There had been merely a couple of variety within Sulaman shore; the dominant D. foresti (SL 2.83 ± step one.03 mm) and something Diogenes sp. (Figure 3b) which was too small (SL step 1.53 ± 0.42 mm) to be totally recognized. Assortment and evenness indices weren’t determined for hermit crabs within the Sulaman on account of a reduced number of types. Density out-of D. foresti generally diminished regarding 3.33 ± 2.65 ind/yards dos during the 0 m in order to 0.16 ± 0.twenty eight ind/meters 2 at 31 meters (Shape 2e). Diogenes sp. was absent on 29 yards and took place few which have a complete imply occurrence out of 0.21 ± 0.32 ind/m 2 . Chi-rectangular decide to try shown no organization (? dos = 0.fifteen, df = 2, p > 0.05) between hermit crab species and you can channel within the Sulaman coastline.

step three.2 Cover explore

At Sepangar coast, all in all, 29 shell variety were used of the hermit crabs with many occupied shells are Clypeomorus batillariaeformis (%) with C. bifasciata (8.61%) and you may Rhinoclavis sinensis (4.13%) when you find yourself usage of different kind regarding shells have been significantly reduced (Desk step three). Shells used by hermit crabs at the station 5 appeared to be one particular varied (H? = 1.30, J? = 0.51) certainly every station while channel 2 was at least diverse (H? = 0.66, J? = 0.30) (Table cuatro). New composition out-of hermit crabs according to research by the five really occupied shells are shown in Shape cuatro. The shell group ‘others’ signifies the fresh new cumulative ratio of hermit crabs because of the types you to definitely used the remaining twenty six cover products. New blank shells out of C. batillariaeformis composed the majority of shells utilized by every hermit crab varieties whereas shells from C. bifasciata portrayed nice ratio out of shells employed by C. striolatus (17%), D. tumidus (11%) and you may D. klaasi (6%) (Contour 4). During the Sulaman shore, merely several shells were used from the hermit crabs: Nassarius livescens and you can Cerithidea cingulata with the latter occupied of the 98% of hermit crabs (Desk step 3).
