Shell occupation by the South Atlantic endemic hermit crab Loxopagurus loxochelis (Moreira, 1901) (Anomura: Diogenidae)

Abstract: -The evaluation of population characteristics, particularly those of endemic species, aids in population preservation and management. Hermit crabs present an innate behavior of occupying shells, which tends to individual needs and limits their distribution. This study characterized the pattern of occupation of gastropod shells by the hermit Loxopagurus loxochelis in three bays of the southwestern coast of Brazil. Monthly collections were made from January/1998 to December/1999 in the bays Ubatumirim (UBM), Uba… Show more

“…Loxopagurus loxochelis occupied a considerable number of shells of gastropod species (12), similar to the numbers registered by Ayres-Peres et al (2012) (14 species) and Frameschi et al (2013) (10 species), also on the North coast of São Paulo state. Olivancillaria urceus was one of main resources used by this species in this study (37.5%), compared with a frequency in previous studies of 77.7% (Ayres-Peres et al, 2012) and 31.3% (Frameschi et al, 2013).…”

According to Wait and Schoeman (2012), shell selection is a process that involves individual and sexual preferences in different dimensions, with the aim of providing the best protection for the hermit crab and sufficient space for the development of embryos and their oxygenation, because females that inhabit very small shells show difficulties in reproducing or reduced rates of reproduction (Fantucci et al, 2008).…”

“…Based on this assumption, the results of the present study suggest that, during juvenile growth, the morphology of the animal and the shell are not determining factors in the choice of the resource, given that hermit crabs categorized as juveniles (both males and females) are found in a shells with a variety of shapes. The variation of occupation in the smaller size classes was verified by Ayres-Peres et al (2012) and Frameschi et al (2013a) when they analyzed the utilization of shells by the hermit crab, L. loxochelis at the same site of the present study. This diverse exploration of shell species by D. insignis in the first four size classes is likely because of the presence of a larger availability of gastropod species with varied sizes in the environment .…”

“…During the CA, the associations of both types of variables (demographic group and spatial abundance) were summarized by the frequency of each table cell, and then positioned in a geometric dimensional space, since the positions of each line and column were consistent with the associations of the table (as performed by Frameschi et al 2013Frameschi et al , 2014. Statistical significance of the eigenvalues and proportion was assessed using the chisquared test with a simulated p-value (based on 2000 randomizations) (Nenadic and Greenacre 2007).…”
