step 3.1 Range and wealth of your own hermit crab neighborhood

step 3.step 1.step one Sepangar coast

A total of 850 specimens was indeed built-up spanning of five kinds owned by one or two genera on the friends Diogenidae: Clibanarius merguiensis, C. striolatus, Diogenes klaasi, D. pallescens and you will D. tumidus. The greatest types was C. striolatus (SL 5.64 ± dos.55 mm), followed closely by C. merguiensis (5.45 ± 2.forty-eight mm), D. pallescens (cuatro.37 ± 2.39 mm), D. klaasi (cuatro.28 ± 2.37 mm) and you will D. tumidus (cuatro.fourteen ± step 1.86 mm). A range try registered during the 100 meters (H? = step one.09) while the reduced on 0 yards (H? = 0.00) in which only 1 variety (D. klaasi) try introduce. Hermit crab species in the a hundred meters was in fact the quintessential equally marketed (J? = 0.79) because they had been at least equally distributed within 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 hookupdate free trial 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.

Suggest thickness (+SD) out of hermit crabs by species within an enthusiastic (e-f) coastlines. D. pallescens regarding Sepangar wasn’t provided because of really low thickness and you will is missing in the most common stations.

3.1.2 Sulaman shore

There had been just a couple types from the Sulaman coast; the principal D. foresti (SL dos.83 ± 1.03 mm) and something Diogenes sp. (Profile 3b) that has been too little (SL step one.53 ± 0.42 mm) to-be completely known. Variety and you can evenness indicator just weren’t computed getting hermit crabs into the Sulaman because of a minimal number of varieties. Thickness out of D. foresti essentially diminished of step 3.33 ± 2.65 ind/meters dos from the 0 yards so you’re able to 0.16 ± 0.28 ind/yards dos on 31 m (Profile 2e). Diogenes sp. try missing within 29 m and you will occurred in small number that have a complete imply occurrence from 0.21 ± 0.32 ind/m 2 . Chi-square shot shown no relationship (? 2 = 0.15, df = 2, p > 0.05) between hermit crab species and you can route in the Sulaman shore.

3.2 Layer fool around with

On Sepangar shore, a total of 31 shell species were used because of the hermit crabs with most filled shells getting Clypeomorus batillariaeformis (%) followed by C. bifasciata (8.61%) and you may Rhinoclavis sinensis (4.13%) if you’re use of other type from shells was in fact markedly lowest (Desk step three). Shells employed by hermit crabs in the channel 5 looked like one particular diverse (H? = step one.31, J? = 0.51) among all the channels while station dos are the least varied (H? = 0.66, J? = 0.30) (Table cuatro). New constitution from hermit crabs according to the five very occupied shells was shown for the Profile cuatro. Brand new shell class ‘others’ is short for new collective proportion of hermit crabs by the kinds one used the left twenty six layer brands. This new empty shells regarding C. batillariaeformis made most shells used by every hermit crab species while shells out of C. bifasciata illustrated generous ratio from shells used by C. striolatus (17%), D. tumidus (11%) and you will D. klaasi (6%) (Profile 4). Within Sulaman coast, simply a couple shells were utilized from the hermit crabs: Nassarius livescens and you can Cerithidea cingulata toward latter occupied of the 98% of your hermit crabs (Table step three).
