Precopulatory mate guarding in the hermit crab Pagurus middendorffii (Brandt) (Decapoda: Paguridae): effects of population parameters on male guarding duration
Abstract The effects of sex ratio, competitor size, and the encounter rate with females on the duration of male precopulatory guarding were tested in the hermit crab Pagurus middendorffii (Brandt,Expand

Mate choice by males of the hermit crab Pagurus filholi: Do males assess ripeness and/or fecundity of females?
Males of the hermit crab, Pagurusfilholi, often grasp the edges of shells occupied by females and drag them during the mating season. This behavior was experimentally confirmed to be a precopulatoryExpand

The design and production of a sexual signal: Hoods and hood building by male fiddler crabs Uca musica
Courting male fiddler crabs Uca musica sometimes build hoods at the entrances of their burrows to which females come for mating. Females differentially orient to burrows with hoods and thereby show aExpand

Impacts of male-only fishing and sperm limitation in manipulated populations of an unfished crab, Hapalogaster dentata
We examined how changes in population structure resulting from fishing selectively for males, including a decrease in male size and a skewed sex ratio toward females, might influence the reproductiveExpand

Antipredator defence of the hermit crab Pagurus filholi induced by predatory crabs
Hermit crabs have two antipredator tactics: taking refuge in its shell and fleeing. We examined the following two hypotheses using the hermit crab Pagurus filholi: (1) hermit crabs change theirExpand
