step 3.1.step 1 Sepangar coast
A total of 850 specimens had been amassed comprising of 5 variety owned by several genera regarding family members Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you can D. tumidus. The biggest kinds was C. striolatus (SL 5.64 ± 2.55 mm), followed by C. merguiensis (5.forty-five ± 2.48 mm), D. pallescens (cuatro.37 ± 2.39 mm), D. klaasi (4.28 ± dos.37 mm) and you will D. tumidus (cuatro.14 ± 1.86 mm). The most effective assortment was recorded during the one hundred yards (H? = step 1.09) as the lowest during the 0 m (H? = 0.00) in which only one types (D. klaasi) try introduce. Hermit crab kinds on one hundred m was basically probably the most evenly distributed (J? = 0.79) as they have been the least equally delivered during the 0 m (J? = 0.00) (Table 2).
The overall highest density was reported for utilizar un enlace web 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) out of hermit crabs because of the kinds at a keen (e-f) shores. D. pallescens out of Sepangar was not incorporated due to really low thickness and you can is missing in the most common channels.
step three.step one.2 Sulaman shore
There are only a couple of types from the Sulaman shore; the fresh dominant D. foresti (SL dos.83 ± step 1.03 mm) plus one Diogenes sp. (Profile 3b) which had been too little (SL 1.53 ± 0.42 mm) to be fully understood. Assortment and you may evenness indices just weren’t determined to possess hermit crabs when you look at the Sulaman on account of a minimal quantity of kinds. Occurrence out-of D. foresti fundamentally diminished regarding step three.33 ± dos.65 ind/meters dos within 0 yards in order to 0.sixteen ± 0.28 ind/meters 2 in the 29 yards (Shape 2e). Diogenes sp. are absent during the 29 meters and you may took place small number that have a complete mean thickness off 0.21 ± 0.thirty two ind/meters dos . Chi-rectangular sample found zero organization (? 2 = 0.15, df = dos, p > 0.05) anywhere between hermit crab kinds and you will route for the Sulaman coastline.
3.2 Layer explore
In the Sepangar shore, a maximum of 29 cover varieties were utilized because of the hermit crabs with a lot of filled shells getting Clypeomorus batillariaeformis (%) followed by C. bifasciata (8.61%) and you can Rhinoclavis sinensis (4.13%) when you’re usage of different kind regarding shells have been significantly reduced (Dining table step 3). Shells used by hermit crabs during the route 5 looked like by far the most varied (H? = step one.31, J? = 0.51) one of all of the programs whereas route dos was at least varied (H? = 0.66, J? = 0.30) (Table cuatro). Brand new constitution off hermit crabs according to the four most occupied shells was revealed when you look at the Profile 4. Brand new layer classification ‘others’ stands for the brand new cumulative ratio away from hermit crabs by types one made use of the kept twenty six layer items. This new blank shells out of C. batillariaeformis made many shells utilized by most of the hermit crab types while shells away from C. bifasciata represented big proportion off shells used by C. striolatus (17%), D. tumidus (11%) and D. klaasi (6%) (Figure 4). On Sulaman coastline, only several shells were utilized because of the hermit crabs: Nassarius livescens and you may Cerithidea cingulata on latter occupied of the 98% of your hermit crabs (Table step three).
