step 3.step 1.1 Sepangar shore
A maximum of 850 specimens were collected comprising of five species owned by a couple genera regarding relatives Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you will D. tumidus. The biggest variety is C. striolatus (SL 5.64 ± dos.55 mm), accompanied by C. merguiensis (5.45 ± 2.48 mm), D. pallescens (cuatro.37 ± 2.39 mm), D. klaasi (4.28 ± 2.37 mm) and you will D. tumidus (4.fourteen ± step one.86 mm). Top range are recorded on a hundred m (H? = step 1.09) since the low from the 0 meters (H? = 0.00) in which singular variety (D. klaasi) is expose. Hermit crab types during the one hundred yards had been the most evenly distributed (J? = 0.79) because they was at least uniformly marketed from the 0 yards (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 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 occurrence (+SD) regarding hermit crabs from the varieties in the an enthusiastic (e-f) shores. D. pallescens out of Sepangar was not provided because of suprisingly low occurrence and try missing in most station.
step three.1.2 Sulaman coastline
There have been simply a couple of types during the Sulaman coastline; brand new prominent D. foresti (SL 2.83 ± 1.03 mm) and something Diogenes sp. (Figure 3b) which had been too small (SL step 1.53 ± 0.42 mm) becoming fully seniorpeoplemeet indirim kodu understood. Range and you can evenness indices just weren’t determined to own hermit crabs during the Sulaman on account of a low number of types. Thickness out-of D. foresti essentially reduced from step three.33 ± 2.65 ind/yards 2 on 0 meters so you can 0.16 ± 0.twenty eight ind/meters dos in the 31 m (Figure 2e). Diogenes sp. are absent at 30 yards and you may took place small number having an overall suggest density away from 0.21 ± 0.thirty two ind/meters 2 . Chi-square try found zero connection (? 2 = 0.15, df = 2, p > 0.05) between hermit crab variety and route inside Sulaman coast.
step 3.dos Cover use
At Sepangar coastline, a total of 29 cover kinds were utilized by hermit crabs with a lot of filled shells getting Clypeomorus batillariaeformis (%) followed closely by C. bifasciata (8.61%) and you may Rhinoclavis sinensis (cuatro.13%) if you’re use of other type out of shells had been significantly low (Table step three). Shells employed by hermit crabs at station 5 appeared to be the most varied (H? = 1.31, J? = 0.51) one of the station whereas route 2 is the least diverse (H? = 0.66, J? = 0.30) (Table 4). New constitution away from hermit crabs in accordance with the five extremely filled shells is shown within the Shape cuatro. Brand new layer group ‘others’ means brand new collective proportion off hermit crabs by species you to used the leftover twenty six cover versions. The latest empty shells off C. batillariaeformis made up more shells used by all hermit crab species whereas shells out-of C. bifasciata represented generous ratio regarding shells utilized by C. striolatus (17%), D. tumidus (11%) and you may D. klaasi (6%) (Shape cuatro). From the Sulaman shore, simply a couple shells were used from the hermit crabs: Nassarius livescens and you can Cerithidea cingulata into the latter filled from the 98% of your hermit crabs (Table 3).
