step 3.step one.step 1 Sepangar coastline

A maximum of 850 specimens was collected comprising of 5 species owned by a couple genera in the loved ones Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you will D. tumidus. The biggest species is actually C. striolatus (SL 5.64 ± 2.55 mm), followed by C. merguiensis (5.forty-five ± 2.forty-eight mm), D. pallescens (4.37 ± 2.39 mm), D. klaasi (4.twenty eight ± dos.37 mm) and you may D. tumidus (cuatro.fourteen ± 1.86 mm). The greatest assortment was filed within 100 yards (H? = 1.09) since the low within 0 meters (H? = 0.00) in which only one variety (D. klaasi) are expose. Hermit crab kinds from the 100 meters was indeed the essential equally delivered (J? = 0.79) because they was basically at least equally delivered on 0 m (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.

Imply thickness (+SD) of hermit crabs because of the varieties at an enthusiastic (e-f) coastlines. D. pallescens off Sepangar was not integrated due to really low thickness and is actually missing for the majority programs.

step 3.1.2 Sulaman shore

There have been merely two kinds at the Sulaman coastline; the latest dominant D. foresti (SL dos.83 ± step one.03 mm) and one Diogenes sp. (Figure 3b) that was too small (SL step one.53 ± 0.42 mm) becoming totally known. Diversity and you can evenness indices were https://datingranking.net/tr/xpress-inceleme/ not determined getting hermit crabs in the Sulaman on account of a reduced level of variety. Occurrence of D. foresti basically diminished away from step 3.33 ± 2.65 ind/meters 2 during the 0 m so you can 0.16 ± 0.twenty-eight ind/yards dos at the 30 meters (Shape 2e). Diogenes sp. are absent at the 29 m and took place few which have a complete mean thickness away from 0.21 ± 0.thirty two ind/m 2 . Chi-rectangular shot shown zero connection (? dos = 0.15, df = 2, p > 0.05) ranging from hermit crab species and route during the Sulaman coastline.

step 3.2 Cover have fun with

At the Sepangar shore, a maximum of 29 layer kinds were used by the hermit crabs with a lot of occupied shells becoming Clypeomorus batillariaeformis (%) followed closely by C. bifasciata (8.61%) and Rhinoclavis sinensis (cuatro.13%) while use of different kind away from shells were markedly lowest (Desk step 3). Shells utilized by hermit crabs on route 5 appeared to be probably the most diverse (H? = 1.29, J? = 0.51) certainly one of every stations whereas route dos are minimum of diverse (H? = 0.66, J? = 0.30) (Desk 4). The fresh new structure from hermit crabs according to research by the five extremely occupied shells is actually shown into the Figure cuatro. New layer classification ‘others’ stands for the fresh new cumulative proportion from hermit crabs from the variety one to used the kept twenty-six cover systems. The latest empty shells out of C. batillariaeformis made-up the majority of shells employed by all the hermit crab species whereas shells out of C. bifasciata portrayed ample ratio out of shells employed by C. striolatus (17%), D. tumidus (11%) and D. klaasi (6%) (Contour 4). In the Sulaman shore, only a few shells were used because of the hermit crabs: Nassarius livescens and Cerithidea cingulata to your second filled from the 98% of your hermit crabs (Dining table step three).
