Animals often need to signal to attract mates and behavioural signalling may impose
substantial energetic and fitness costs to signallers. Consequently, individuals often …

Females use multiple cues from different sensory modalities to choose males of high
phenotypic or genetic quality to mate with. Fish may use visual and acoustic communication …

The present study describes the capture adaptation and reproduction of wild Lophiosilurus
alexandri broodstock in laboratory conditions. There were two periods when capturing was …

Acoustic signals can encode crucial information about species identity and individual
quality. We recorded and compared male courtship drum sounds of the sand goby …

To date, mate choice studies have mostly focused on establishing which mates are chosen
or how the choices are performed. Here, we combined these two approaches by empirically …

Human-induced eutrophication, resulting in increased algal growth and water turbidity, is an
alarming problem in aquatic systems. Many studies have focused on the effects of algal …

In aquatic environments, externally developing eggs are in constant contact with the
surrounding water, highlighting the significance of water parameters and pathogens for egg …

Highlights•Nest defence is a particularly costly component of parental care.•Yet, little is
known about how nest-builders react to the threat of future predation.•Egg predator …

Whether premating isolation is achieved by male‐specific, female‐specific or sex‐
independent assortative preferences often depends on the underlying evolutionary …

Conditional mating strategies enable individuals to modulate their mating behaviour
depending on 'individual status' to maximise fitness. Theory predicts that variation in …
