3.step one.step one Sepangar coastline
A total of 850 specimens was in fact built-up spanning of 5 variety owned by a few genera from the friends Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you can D. tumidus. The biggest species was C. striolatus (SL 5.64 ± dos.55 mm), followed by C. merguiensis (5.forty five ± dos.forty eight mm), D. pallescens (4.37 ± 2.39 mm), D. klaasi (4.twenty eight ± 2.37 mm) and D. tumidus (4.14 ± 1.86 mm). The very best range was filed at a hundred yards (H? = step 1.09) since low at 0 meters (H? = 0.00) in which one variety (D. klaasi) try establish. Hermit crab kinds within 100 yards were the most uniformly marketed (J? = 0.79) while they was indeed minimum of equally distributed from the 0 yards (J? = 0.00) (Desk 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 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 thickness (+SD) regarding hermit crabs by types from the a keen (e-f) coastlines. D. pallescens off Sepangar was not incorporated on account of suprisingly low density and you can are absent in the most common programs.
3.1.2 Sulaman coastline
There were only several kinds within Sulaman coastline; the brand new principal D. foresti (SL 2.83 ± step one.03 mm) plus one Diogenes sp. (Shape 3b) which was too tiny (SL 1.53 ± 0.42 mm) to be completely recognized. Diversity and you may evenness indices weren’t calculated getting hermit crabs into the Sulaman on account of a reduced level of variety. Occurrence off D. foresti generally reduced out of step three.33 ± 2.65 ind/m 2 in the 0 m to help you 0.16 ± 0.28 ind/m 2 in the 31 yards (Shape 2e). Diogenes sp. is actually missing at 31 m and you will took place few that have a total imply thickness regarding 0.21 ± 0.thirty-two ind/yards dos . Chi-square shot shown no relationship (? 2 = 0.fifteen, df = dos, p > 0.05) between hermit crab species and station when you look at the Sulaman coast.
step three.dos Cover play with
At Sepangar coast, a total of 31 cover kinds were utilized because of the hermit crabs with many filled shells getting Clypeomorus batillariaeformis (%) followed closely by C. bifasciata (8.61%) and you may Rhinoclavis sinensis (cuatro.13%) when you find yourself utilization of other type of shells was basically significantly lower (Dining table 3). Shells utilized by hermit crabs during the channel 5 appeared as if by far the most varied (H? = 1.29, J? = 0.51) one of most of the channels whereas station dos is at least varied (H? = 0.66, J? = 0.30) (Desk 4). Brand new composition away from hermit crabs in accordance with the five extremely occupied shells are shown in the Contour cuatro. The cover class ‘others’ means the latest collective ratio away from hermit crabs by types you to made use of the left twenty-six shell items. The fresh empty shells regarding C. batillariaeformis made up most shells employed by most of the hermit crab variety whereas shells off C. bifasciata illustrated reasonable ratio out of shells employed by C. striolatus (17%), D. tumidus (11%) and you will D. klaasi (6%) (Profile cuatro). On Sulaman coast, merely a couple of shells were used by the hermit crabs: Nassarius livescens and you will Cerithidea cingulata for skout isim deÄŸiÅŸtirme the second occupied of the 98% of hermit crabs (Desk step three).
