step three.step one Diversity and you can wealth of your own hermit crab neighborhood

3.step 1.step 1 Sepangar shore

All in all, 850 specimens were amassed spanning of five varieties owned by two genera in the family Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and D. tumidus. The biggest varieties is C. striolatus (SL 5.64 ± 2.55 mm), accompanied by C. merguiensis (5.45 ± dos.48 mm), D. pallescens (cuatro.37 ± dos.39 mm), D. klaasi (cuatro.twenty eight ± dos.37 mm) and you will D. tumidus (cuatro.fourteen ± step one.86 mm). Top variety is filed at one hundred meters (H? = 1.09) since lower at the 0 yards (H? = 0.00) in which only 1 species (D. klaasi) is establish. Hermit crab types on one hundred yards were the absolute most equally distributed (J? = 0.79) while they was basically minimum of uniformly delivered on 0 yards (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). Equestrian dating online 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.

Imply occurrence (+SD) out of hermit crabs by varieties on an (e-f) coastlines. D. pallescens out-of Sepangar was not included on account of low density and you will is missing for the majority station.

step three.1.2 Sulaman coastline

There are just a couple kinds at the Sulaman shore; the dominating D. foresti (SL dos.83 ± 1.03 mm) and something Diogenes sp. (Shape 3b) that was too small (SL 1.53 ± 0.42 mm) as totally recognized. Assortment and you will evenness indices were not computed for hermit crabs inside Sulaman because of a reduced amount of variety. Thickness away from D. foresti essentially diminished away from step three.33 ± 2.65 ind/meters dos at 0 meters so you can 0.16 ± 0.twenty eight ind/meters 2 at the 31 meters (Figure 2e). Diogenes sp. was absent in the 31 meters and you can occurred in small number having an overall total mean density off 0.21 ± 0.32 ind/m 2 . Chi-square attempt shown zero organization (? 2 = 0.fifteen, df = 2, p > 0.05) ranging from hermit crab varieties and you will channel for the Sulaman coast.

step 3.2 Cover fool around with

At the Sepangar coast, a total of 31 cover species were used from the hermit crabs with many filled shells getting Clypeomorus batillariaeformis (%) followed by C. bifasciata (8.61%) and you will Rhinoclavis sinensis (4.13%) if you find yourself usage of different kind out-of shells was indeed significantly lower (Table 3). Shells utilized by hermit crabs in the station 5 appeared to be the absolute most varied (H? = step one.30, J? = 0.51) one of all of the stations while channel dos was the least varied (H? = 0.66, J? = 0.30) (Table 4). The fresh structure out of hermit crabs in line with the four extremely filled shells was found inside the Shape cuatro. The newest shell class ‘others’ represents this new collective ratio away from hermit crabs of the variety that made use of the kept 26 shell versions. The newest blank shells of C. batillariaeformis made up more shells utilized by most of the hermit crab species whereas shells off C. bifasciata depicted generous ratio regarding shells utilized by C. striolatus (17%), D. tumidus (11%) and D. klaasi (6%) (Shape cuatro). Within Sulaman coastline, only one or two shells were used from the hermit crabs: Nassarius livescens and you may Cerithidea cingulata towards the second occupied of the 98% of your own hermit crabs (Dining table step three).
