This article analyses the pressures on seahorses and explores conservation responses. It
focuses on seahorses (Hippocampus spp.) but also considers pipefishes and seadragons …

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 …

Comparing five species of pipefish, egg size was significantly larger in species with brood
pouches (Syngnathus typhle, Syngnathus acus and Syngnathus rostellatus) than in species …

The pipefish brood pouch presents a unique mode of parental care that enables males to
protect, osmoregulate, nourish and oxygenate the developing young. Using a very fine O2 …

Offspring fitness generally improves with increasing egg size. Yet, eggs of most aquatic
organisms are small. A common but largely untested assumption is that larger embryos …

In animals with uniparental care, the quality of care provided by one sex can deeply impact
the reproductive success of both sexes. Studying variation in parental care quality within a …

Courtship is an important part of the reproductive process, ensuring reproductive
compatibility and conveying individual quality. One factor in aquatic environments that has …

In species that provide parental care, individuals should invest adaptively in their offspring in
relation to the pre-and post-zygotic care provided by their partners. In the broad-nosed …

Los caballitos de mar (Hippocampus Rafinesque 1810, Syngnathidae) se encuentran
globalmente amenazados debido a la declinación de sus poblaciones. En el presente …

Several studies have shown that mate choice based on condition leads to higher
reproductive success of the choosing individual. Yet, a growing body of literature has failed …
