step 3.step 1.step one Sepangar shore
All in all, 850 specimens was basically obtained comprising of five types belonging to a couple of genera about nearest and dearest Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you can D. tumidus. The greatest variety is actually C. striolatus (SL 5.64 ± 2.55 mm), with C. merguiensis (5.forty-five ± dos.48 mm), D. pallescens (4.37 ± 2.39 mm), D. klaasi (cuatro.28 ± dos.37 mm) and you will D. tumidus (4.14 ± 1.86 mm). The greatest variety was registered within 100 m (H? = 1.09) because the reduced at 0 yards (H? = 0.00) where one kinds (D. klaasi) are introduce. Hermit crab species in the one hundred m was many equally distributed (J? = 0.79) while they had been at least evenly distributed in the 0 m (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 https://datingranking.net/escort-directory/atlanta 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 thickness (+SD) out-of hermit crabs from the kinds from the an (e-f) beaches. D. pallescens away from Sepangar was not integrated because of low density and you will was absent in the most common station.
step 3.step one.dos Sulaman shore
There have been merely one or two types during the Sulaman coastline; brand new prominent D. foresti (SL dos.83 ± 1.03 mm) plus one Diogenes sp. (Profile 3b) which was too tiny (SL step one.53 ± 0.42 mm) becoming totally identified. Variety and evenness indicator were not calculated to own hermit crabs from inside the Sulaman due to a minimal amount of kinds. Density out of D. foresti generally diminished regarding step three.33 ± 2.65 ind/yards 2 in the 0 yards to help you 0.16 ± 0.twenty-eight ind/meters dos on 29 meters (Figure 2e). Diogenes sp. is actually absent at 30 meters and you can took place small number that have a complete indicate thickness regarding 0.21 ± 0.thirty-two ind/yards 2 . Chi-square test shown no connection (? dos = 0.fifteen, df = dos, p > 0.05) between hermit crab types and you will station when you look at the Sulaman coast.
3.dos Shell fool around with
During the Sepangar shore, a maximum of 31 layer types were utilized by hermit crabs with a lot of occupied shells being Clypeomorus batillariaeformis (%) accompanied by C. bifasciata (8.61%) and you may Rhinoclavis sinensis (cuatro.13%) whenever you are usage of other type of shells had been significantly reasonable (Dining table step three). Shells used by hermit crabs at station 5 appeared to be the absolute most diverse (H? = step 1.31, J? = 0.51) among all of the station whereas channel dos is actually at least varied (H? = 0.66, J? = 0.30) (Desk 4). The fresh new constitution out of hermit crabs according to the four very occupied shells is actually revealed inside the Shape cuatro. New layer category ‘others’ stands for the new collective proportion regarding hermit crabs from the kinds one to made use of the left twenty six shell sizes. The fresh blank shells regarding C. batillariaeformis constructed more shells employed by all hermit crab variety whereas shells of C. bifasciata illustrated good proportion out-of shells utilized by C. striolatus (17%), D. tumidus (11%) and you may D. klaasi (6%) (Figure cuatro). At Sulaman shore, only a couple shells were used of the hermit crabs: Nassarius livescens and Cerithidea cingulata on latter filled by the 98% of the hermit crabs (Table step three).
