3.step 1.step one Sepangar shore
A total of 850 specimens had been gathered spanning of 5 varieties owned by several genera throughout the members of the family Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you may D. tumidus. The largest varieties are C. striolatus (SL 5.64 ± 2.55 mm), accompanied by C. merguiensis (5.forty five ± dos.48 mm), D. pallescens (4.37 ± dos.39 mm), D. klaasi (4.28 ± dos.37 mm) and you will D. tumidus (4.14 ± step 1.86 mm). The number one range is registered within one hundred meters (H? = 1.09) since the reduced within 0 yards (H? = 0.00) where one varieties (D. klaasi) are establish. Hermit crab kinds in the 100 m have been one particular equally marketed (J? = 0.79) as they have been minimum of equally distributed on 0 yards (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 escort Pasadena 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 density (+SD) from hermit crabs of the types at the an enthusiastic (e-f) beaches. D. pallescens out-of Sepangar wasn’t provided because of really low occurrence and you may are missing in most channels.
3.1.dos Sulaman shore
There are merely one or two variety on Sulaman coast; the newest prominent D. foresti (SL 2.83 ± 1.03 mm) and something Diogenes sp. (Contour 3b) which was too little (SL step one.53 ± 0.42 mm) as fully understood. Variety and you will evenness indices just weren’t determined to possess hermit crabs in Sulaman due to a decreased level of species. Density from D. foresti generally decreased away from step three.33 ± 2.65 ind/yards dos during the 0 yards in order to 0.sixteen ± 0.twenty-eight ind/meters dos at the 29 meters (Shape 2e). Diogenes sp. try missing within 29 yards and you may took place few which have a total suggest thickness out-of 0.21 ± 0.32 ind/yards 2 . Chi-rectangular decide to try revealed no relationship (? dos = 0.fifteen, df = dos, p > 0.05) between hermit crab kinds and you will station inside Sulaman coast.
step three.2 Layer play with
During the Sepangar coastline, a maximum of 29 layer kinds were used of the hermit crabs with many occupied shells being Clypeomorus batillariaeformis (%) accompanied by C. bifasciata (8.61%) and you may Rhinoclavis sinensis (cuatro.13%) if you’re usage of other type from shells was indeed significantly lower (Table step three). Shells utilized by hermit crabs at the station 5 looked like the most varied (H? = 1.29, J? = 0.51) among most of the programs whereas channel dos is minimum of varied (H? = 0.66, J? = 0.30) (Desk cuatro). The structure away from hermit crabs according to research by the five very occupied shells was found inside Contour 4. The layer category ‘others’ stands for the fresh new cumulative ratio of hermit crabs because of the types one to made use of the remaining twenty-six shell items. The fresh new empty shells out-of C. batillariaeformis made up more shells used by all of the hermit crab kinds whereas shells out of C. bifasciata illustrated generous ratio regarding shells used by C. striolatus (17%), D. tumidus (11%) and you will D. klaasi (6%) (Figure cuatro). On Sulaman coastline, just several shells were utilized of the hermit crabs: Nassarius livescens and you may Cerithidea cingulata on the second occupied from the 98% of hermit crabs (Table step 3).
