For sexual selection to act on a given sex, there must exist variation in the reproductive
success of that sex as a result of differential access to mates or fertilisations. The …

The Darwin–Bateman paradigm recognizes competition among males for access to multiple
mates as the main driver of sexual selection. Increasingly, however, females are also being …

The seahorses, pipefishes and seadragons (Syngnathidae) are among the few vertebrates
in which pregnant males incubate developing embryos. Syngnathids are popular in studies …

Sexual selection is a cornerstone of evolutionary theory, but measuring it has proved
surprisingly difficult and controversial. Various proxy measures—eg, the Bateman gradient …

Male pregnancy in seahorses, pipefishes and sea dragons (family Syngnathidae)
represents a striking reproductive adaptation that has shaped the evolution of behaviour and …

In two experiments, radioactively labelled nutrients (either 3H‐labelled amino‐acid mixture
or 14C‐labelled glucose) were tube‐fed to brooding male Syngnathus typhle. Both nutrients …

The goal of this review was to provide a historical overview of how molecular techniques
have increased the understanding of the ecology and evolution of the family Syngnathidae …

Understanding how demographic processes influence mating systems is important to
decode ecological influences on sexual selection in nature. We manipulated sex ratio and …

Empirical studies of sexual selection often focus on events occurring either before or after
mating but rarely both and consequently may fail to discern the relative magnitudes and …

The occurrence of male pregnancy in the family Syngnathidae (seahorses, pipefishes, and
sea dragons) provides an exceptionally fertile system in which to investigate issues related …
