Summary Traits which differ among species in a genus are considered to be the product of relatively rapid evolution. Laboratory studies indicate that copulation differs between two species of the banana slug Ariolimax with A. dolichophallus having a pattern of a single, long duration (typically greater than 1 h) intromission which is simultaneously reciprocal, and A. californicus having mating encounters typically involving a bout of brief (typically 10–20 min) unilateral intromissions… 

A review of mating behavior in slugs of the genus Deroceras (Pulmonata: Agriolimacidae)*

It is hypothesized that the radiation of mating behaviors and associated structures has been driven by an arms race resulting from conflicting interests of mating partners over sperm donation and use and this could also have increased the rate of speciation in Deroceras.

Phally polymorphism and reproductive biology in Ariolimax (Ariolimax) buttoni (Pilsbry and Vanatta, 1896) (Stylommatophora: Arionidae)*

Phally polymorphism, uniparental reproduction, and the variation in generation time should play important roles in determining the variance of mating success and the potential for sexual selection in this hermaphroditic species.

Mating in Veronicella sloanii (Cuvier, 1817) (Veronicellidae)

Aggressive behavior during mating in this slug was manifested by non-mating individuals pushing themselves between mating pairs resulting in the withdrawal of the penis of the mating pairs and cessation of copulation.

Records of the slugs Ariolimax columbianus (Ariolimacidae) and Prophysaon foliolatum (Arionidae) imported into Sweden

Two North American slug species are reported from three locations in southern Sweden: three records (in 2005, 2014 and 2015) of Ariolimax columbianus (Gould) and one 2005 record of Prophysaon

A literature database on the mating behavior of stylommatophoran land snails and slugs*

This work reviews studies on the mating behavior of snails and slugs and creates a central access point and database for use as a resource by those interested in stylommatophoran mating behavior.

Female loggerhead sea turtles (Caretta caretta L.) rarely remate during nesting season

Benefits to loggerhead females likely equal their costs and subsequent mating is likely determined by female preference, suggesting that females likely mate at the beginning of the season and use stored sperm for multiple clutches.

Tales of two snails: sexual selection and sexual conflict in Lymnaea stagnalis and Helix aspersa.

Findings support the existence of sexual conflict in simultaneously hermaphroditic snails, and its importance for the evolution of mating behaviors and reproductive morphologies is discussed.

Reproductive strategies in hermaphroditic gastropods: Conceptual and empirical approaches

The suggestions are to focus on sex-biased traits, to take biologically reliable measurements at both the pre- and post-copulatory level that relate to reproductive success, and to examine the fitness consequences of biased sex allocation.



Behavior Patterns of the Aplysiid Gastropod Bursatella leachii in Its Natural Habitat and in the Laboratory

The rich behavioral repertoire exhibited by B. leachii, and the ease with which these animals are observed in their native habitat, provide favorable systems for studying neuronal mechanisms involved in the organization and evolution of complex behavior.

Sex economy in benthic polychaetes

Simultaneous hermaphroditism is stabilized by slow sperm production and regular egg trading between partners of a pair and some 80% of the physiological reproductive effort is allocated to the female functions.

Sexual conflict in simultaneous hermaphrodites: evidence from serranid fishes

A comparative analysis of the mating systems described for a group of species of simultaneously hermaphroditic serranid fishes offers evidence that cheating in the male role is found in all of the species studied and explains the harem polygyny system of two species.

Polygyrid land snail phylogeny: external sperm exchange, early North American biogeography, iterative shell evolution

A fresh assessment of reproductive behaviour and anatomy, combined with new allozyme data, results in a phylogenetic hypothesis for the 23 polygyrid genera that differs substantially from previous

Intra-sexual selection in Drosophila.

Epigamic selection includes the major part of what Darwin meant by sexual selection, and is introduced to apply to characters which increased the fertility of a given mating and therefore had a selective value for the species as a whole.

Simultaneous hermaphroditism and sexual selection.

It is suggested that egg production by simultaneous hermaphrodites also obeys this principle-that fertilized eggproduction by an individual is not limited by sperm availability, but by resources allocated to eggs.
