step three.step 1.1 Sepangar shore
A maximum of 850 specimens had been collected comprising of 5 species belonging to a couple of genera in the household members Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and D. tumidus. The biggest variety try C. striolatus (SL 5.64 ± dos.55 mm), followed closely by C. merguiensis (5.forty five ± 2.forty-eight mm), D. pallescens (4.37 ± 2.39 mm), D. klaasi (4.28 ± dos.37 mm) and you can D. tumidus (4.14 ± step 1.86 mm). The number one assortment was submitted in the 100 m (H? = 1.09) since the lowest at 0 yards (H? = 0.00) where one species (D. klaasi) is establish. Hermit crab species at a hundred yards had been probably the most uniformly delivered (J? = 0.79) as they were at least equally distributed on 0 yards (J? = 0.00) (Dining 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 m (0.22 ± https://datingranking.net/web/ 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 thickness (+SD) out-of hermit crabs from the kinds in the a keen (e-f) shores. D. pallescens of Sepangar was not included because of suprisingly low density and you will is actually absent for the majority stations.
step three.step one.2 Sulaman coastline
There had been simply two types within Sulaman coast; the newest prominent D. foresti (SL 2.83 ± 1.03 mm) and something Diogenes sp. (Profile 3b) that has been too small (SL step 1.53 ± 0.42 mm) becoming completely understood. Variety and you may evenness indicator just weren’t computed for hermit crabs when you look at the Sulaman on account of a minimal number of variety. Thickness away from D. foresti fundamentally reduced regarding 3.33 ± 2.65 ind/m 2 from the 0 meters to 0.sixteen ± 0.twenty eight ind/yards dos within 31 meters (Profile 2e). Diogenes sp. are missing during the 31 meters and you can occurred in few having an overall total suggest density off 0.21 ± 0.thirty-two ind/m 2 . Chi-square try found no organization (? 2 = 0.fifteen, df = 2, p > 0.05) anywhere between hermit crab varieties and station in the Sulaman shore.
step 3.dos Shell have fun with
At the Sepangar shore, all in all, 29 shell kinds were utilized of the hermit crabs with many occupied shells are Clypeomorus batillariaeformis (%) followed by C. bifasciata (8.61%) and you may Rhinoclavis sinensis (4.13%) when you find yourself use of other type regarding shells was indeed significantly reasonable (Dining table step 3). Shells used by hermit crabs on station 5 looked like more varied (H? = step 1.29, J? = 0.51) certainly most of the station while station 2 try at least diverse (H? = 0.66, J? = 0.30) (Desk cuatro). The brand new composition off hermit crabs according to research by the four most occupied shells was shown inside Figure cuatro. The fresh new shell classification ‘others’ represents the latest collective ratio of hermit crabs because of the types you to utilized the leftover twenty six shell items. The fresh blank shells out-of C. batillariaeformis made more shells utilized by most of the hermit crab variety whereas shells out of C. bifasciata depicted nice ratio regarding shells employed by C. striolatus (17%), D. tumidus (11%) and you can D. klaasi (6%) (Profile cuatro). Within Sulaman coastline, merely a couple shells were utilized because of the hermit crabs: Nassarius livescens and you may Cerithidea cingulata to the latter filled because of the 98% of your own hermit crabs (Desk step three).
