In many animal species, males may exhibit one of several discrete, alternative ways of
obtaining fertilisations, known as alternative reproductive tactics (ARTs). Males exhibiting …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

Males that exhibit alternative reproductive tactics (ARTs) often differ in the risk of sperm
competition and the energetic trade-offs they experience. The resulting patterns of selection …

With their large brains, elaborate sense organs and complex behaviour, cephalopods are
among the world's most highly evolved invertebrates. This second edition summarises the …

Sperm competition is a post‐copulatory, sexual selection force that, together with phylogeny
and fertilization mode, has been regarded as one of the main factors explaining the diversity …

Here, three researchers who have recently embarked on careers in cephalopod biology
discuss the current state of the field and offer their hopes for the future. Seven major topics …

Species preservation depends on the success of fertilization. Sperm are uniquely equipped
to fulfill this task, and, although several mechanisms are conserved among species, striking …

Traditionally, it has been assumed that sperm are a vehicle for genes and nothing more. As
such, the only source of variance in offspring phenotype via the paternal line has been …

Cephalopod life cycles generally share a set of stages that take place in different habitats
and are adapted to specific, though variable, environmental conditions. Throughout the …

Strategic ejaculate adjustments occur when males modify their investment in sperm and
nonsperm components of the ejaculate according to the context. This strategy is expected to …
