Effects of intermating interval on spermatophore size and sperm number in the simultaneously hermaphroditic land snail Arianta arbustorum
We examined the effect of intermating interval on spermatophore size and number of sperm delivered in the simultaneously hermaphroditic land snail, Arianta arbustorum. Snails that remated after 6-7 dExpand

Nutritional stress changes sex-specific reproductive allocation in the simultaneously hermaphroditic land snail Arianta arbustorum
Summary 1 Sex allocation theory predicts that when resources are limited in simultaneous hermaphrodites, the allocation to one sexual function will automatically reduce the resources availableExpand

Sperm allocation in the simultaneously hermaphroditic land snail Arianta arbustorum
To test the idea that individuals of the simultaneously hermaphroditic land snail Arianta arbustorum can control the number of spermatozoa in their spermatophores, we investigated whether theyExpand

Incidence of dart shooting, sperm delivery, and sperm storage in natural populations of the simultaneously hermaphroditic land snail Arianta arbustorum
In several families of terrestrial pulmonates, simultaneously hermaphroditic animals form a sharp, hard, calcified or chitinous structure (the so-called love dart) in the female part of their repro...

A new technique to assess the number of spermatozoa in spermatophores of stylommatophoran gastropods
The infrastructure of molluscan spermatozoa is of systematic significance and has been studied fairly extensively." In contrast, little is known in molluscs on the number of spermatozoa transferredExpand

Sperm delivery and egg production of the simultaneously hermaphroditic land snail Arianta arbustorum exposed to an increased sperm competition risk
Summary Sperm competition theory predicts that males exposed to an increased risk of sperm competition should maximize fertilization prospects by inseminating more sperm per ejaculate. We designed aExpand

Intermating interval and number of sperm delivered in the simultaneously hermaphroditic land snail Arianta arbustorum (Pulmonata : Helicidae)
The number of sperm delivered is an important determinant for achieving fertilization in sperm competition. Hermaphroditic gastropods with short mating intervals may deplete their autosperm reserves.Expand

Isolation of microsatellite markers in the hermaphroditic land snail Arianta arbustorum (Gastropoda)
Five novel polymorphic microsatellite loci are presented for the simultaneously hermaphroditic land snail Arianta arbustorum. The isolation protocol was adapted from Estoup & Turgeon (see below).Expand
