3.1.step one Sepangar coast
A total of 850 specimens have been built-up comprising of five species owned by a couple of genera on nearest and dearest Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you will D. tumidus. The biggest species is C. striolatus (SL 5.64 ± dos.55 mm), accompanied by C. merguiensis (5.45 ± dos.48 mm), D. pallescens (cuatro.37 ± dos.39 mm), D. klaasi (cuatro.twenty-eight ± 2.37 mm) and you can D. tumidus (4.14 ± step one.86 mm). The number one assortment try filed at the a hundred meters (H? = step 1.09) once the reduced at the 0 meters (H? = 0.00) in which only 1 kinds (D. klaasi) is present. Hermit crab kinds from the one hundred meters had been the most equally delivered (J? = 0.79) as they was in fact at least uniformly distributed at 0 meters (J? = 0.00) (Dining 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.
Indicate occurrence (+SD) of hermit crabs because of the variety from the an (e-f) beaches. D. pallescens of Sepangar wasn’t included due to really low occurrence and are absent in the most International dating review common station.
3.step one.2 Sulaman shore
There had been just one or two species from the Sulaman coast; the principal D. foresti (SL 2.83 ± step one.03 mm) and something Diogenes sp. (Figure 3b) which had been too little (SL step 1.53 ± 0.42 mm) are totally recognized. Assortment and you may evenness indicator were not determined to own hermit crabs when you look at the Sulaman on account of a low quantity of varieties. Occurrence out-of D. foresti generally reduced out-of 3.33 ± dos.65 ind/meters dos during the 0 yards in order to 0.16 ± 0.twenty eight ind/meters dos at the 31 meters (Shape 2e). Diogenes sp. try absent during the 29 yards and occurred in few that have a total suggest density out of 0.21 ± 0.32 ind/yards dos . Chi-square attempt found zero relationship (? 2 = 0.fifteen, df = 2, p > 0.05) anywhere between hermit crab variety and you may route within the Sulaman coastline.
3.dos Shell fool around with
Within Sepangar coastline, a maximum of 30 layer variety were utilized because of the hermit crabs with a lot of occupied shells being Clypeomorus batillariaeformis (%) with C. bifasciata (8.61%) and you may Rhinoclavis sinensis (4.13%) while you are using other type regarding shells was indeed markedly lower (Dining table 3). Shells employed by hermit crabs from the station 5 looked like the quintessential varied (H? = 1.30, J? = 0.51) certainly one of all the channels while route 2 is actually at least varied (H? = 0.66, J? = 0.30) (Table 4). New composition off hermit crabs in accordance with the five very filled shells is actually found within the Shape 4. The newest cover classification ‘others’ represents the collective proportion regarding hermit crabs by varieties you to definitely utilized the remaining twenty-six cover systems. The blank shells out of C. batillariaeformis made up the majority of shells employed by all of the hermit crab kinds while shells regarding C. bifasciata represented generous proportion away from shells employed by C. striolatus (17%), D. tumidus (11%) and D. klaasi (6%) (Shape cuatro). From the Sulaman shore, only two shells were used because of the hermit crabs: Nassarius livescens and you can Cerithidea cingulata with the second occupied by the 98% of hermit crabs (Table step three).
