step three.1.step 1 Sepangar coastline
A total of 850 specimens was basically accumulated comprising of five kinds owned by a couple of genera about friends Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and D. tumidus. The most significant types was C. striolatus (SL 5.64 ± 2.55 mm), accompanied by C. merguiensis (5.45 ± dos.forty eight mm), D. pallescens (cuatro.37 ± dos.39 mm), D. klaasi (cuatro.twenty-eight ± dos.37 mm) and you will D. tumidus (4.14 ± step one.86 mm). The number one range try registered within one hundred yards (H? = 1.09) since the low at the 0 yards (H? = 0.00) in which just one types (D. klaasi) is actually present. Hermit crab types within a hundred meters was indeed the most evenly marketed (J? = 0.79) as they were at least uniformly delivered at the 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.
Mean density (+SD) out of hermit crabs by the species during the an (e-f) coastlines. D. pallescens out of Sepangar was not included due to really low occurrence and try missing for the majority programs.
step three.step 1.2 Sulaman coastline
There were just one or two variety at the Sulaman coast; the fresh dominant D. foresti (SL 2.83 ± step one.03 mm) and something Diogenes sp. (Profile 3b) that was too small (SL step one.53 ± 0.42 mm) becoming completely understood. Range and evenness indices weren’t calculated to own hermit crabs inside Sulaman on account of a low amount of species. Thickness out of D. foresti basically reduced regarding 3.33 ± dos.65 ind/m 2 on 0 yards in order to 0.sixteen ± 0.twenty eight ind/meters dos during the 29 meters (Profile 2e). Diogenes sp. are absent from the 31 yards and you can took place few which have an overall total mean occurrence out of 0.21 ± 0.thirty-two ind/m dos . Chi-rectangular try revealed no organization (? 2 = 0.fifteen, df = dos, p > 0.05) ranging from hermit crab species and station in the Sulaman coastline.
3.dos Cover use
In the Sepangar shore, a maximum of 30 layer kinds were used by the hermit crabs with most occupied shells are Clypeomorus batillariaeformis (%) with C. bifasciata (8.61%) and you may Rhinoclavis sinensis (4.13%) if you’re using other type away from shells was indeed markedly low (Dining table 3). Shells utilized by hermit crabs on station 5 looked like the most varied down dating reddit (H? = 1.29, J? = 0.51) among all of the station while route 2 is the least varied (H? = 0.66, J? = 0.30) (Table cuatro). The constitution from hermit crabs according to the five really filled shells is actually found for the Profile 4. This new layer category ‘others’ is short for the fresh new collective proportion out-of hermit crabs by the varieties one to used the remaining 26 cover designs. The new empty shells regarding C. batillariaeformis made up the majority of shells used by every hermit crab species whereas shells off C. bifasciata portrayed good-sized ratio regarding shells used by C. striolatus (17%), D. tumidus (11%) and you can D. klaasi (6%) (Shape cuatro). At Sulaman coast, just a couple of shells were utilized by hermit crabs: Nassarius livescens and you will Cerithidea cingulata to your second filled by the 98% of your hermit crabs (Desk step 3).
