3.step 1 Assortment and you can wealth of hermit crab area

step 3.step one.1 Sepangar coastline

All in all, 850 specimens was in fact collected comprising of 5 kinds belonging to one or two genera in the members of the family Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you may D. tumidus. The most significant kinds is actually C. striolatus (SL 5.64 ± dos.55 mm), accompanied by C. merguiensis (5.forty five ± dos.48 mm), D. pallescens (cuatro.37 ± 2.39 mm), D. klaasi (4.twenty-eight ± 2.37 mm) and you will D. tumidus (4.fourteen ± 1.86 mm). The number one range is actually submitted on 100 yards (H? = step 1.09) as the lower during the 0 yards (H? = 0.00) in which only 1 variety (D. klaasi) was introduce. Hermit crab varieties on a hundred meters was basically many equally delivered (J? = 0.79) because they had been at least uniformly distributed in the 0 meters (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 ± 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 pinalove türkiye 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 variety from the an enthusiastic (e-f) coastlines. D. pallescens from Sepangar was not included because of suprisingly low occurrence and you can is missing for the majority programs.

3.step one.dos Sulaman coast

There had been merely a few varieties in the Sulaman coast; the dominant D. foresti (SL dos.83 ± 1.03 mm) plus one Diogenes sp. (Figure 3b) that was too tiny (SL 1.53 ± 0.42 mm) getting completely identified. Diversity and you will evenness indicator were not computed to own hermit crabs inside Sulaman due to a reduced level of variety. Density from D. foresti generally decreased away from step 3.33 ± 2.65 ind/m dos in the 0 m to help you 0.sixteen ± 0.twenty-eight ind/meters 2 in the 31 meters (Shape 2e). Diogenes sp. was absent in the 29 m and you will occurred in few having an overall suggest thickness away from 0.21 ± 0.thirty two ind/meters 2 . Chi-rectangular test shown zero connection (? dos = 0.15, df = dos, p > 0.05) between hermit crab variety and you can station into the Sulaman coastline.

step 3.2 Cover fool around with

At the Sepangar coast, all in all, 29 layer variety were utilized because of the hermit crabs with many occupied shells are Clypeomorus batillariaeformis (%) accompanied by C. bifasciata (8.61%) and you can Rhinoclavis sinensis (cuatro.13%) when you find yourself utilization of other type regarding shells was basically markedly lower (Dining table 3). Shells employed by hermit crabs within route 5 looked like more varied (H? = step 1.31, J? = 0.51) among all programs whereas station 2 is actually at least diverse (H? = 0.66, J? = 0.30) (Dining table cuatro). The latest composition of hermit crabs based on the four extremely occupied shells is actually found inside the Shape cuatro. The new shell class ‘others’ signifies new collective proportion off hermit crabs by species you to definitely used the kept twenty six layer sizes. New empty shells out-of C. batillariaeformis comprised many shells used by all of the hermit crab types whereas shells off C. bifasciata represented large ratio away from shells utilized by C. striolatus (17%), D. tumidus (11%) and you may D. klaasi (6%) (Profile cuatro). Within Sulaman shore, simply one or two shells were utilized by the hermit crabs: Nassarius livescens and you may Cerithidea cingulata for the second occupied by the 98% of one’s hermit crabs (Desk 3).
