In lek mating systems, males aggregate and defend arenas where they display for females; females select and mate with a male and then solely raise their offspring. Generally, female visits and copulations increase and ...

Sexual success of males in lek breeding systems is often determined by display activities that require high energetic costs and may represent honest signals of male quality to females. In this context, manakins (Aves, ...

Visual communication is important in many lizard species. One conspicuous visual signal is the headbob display, which consists in a stereotyped up and down movement of the head and/or torso. We analysed male headbob displays ...

Water turbidity deteriorates visibility and thereby may change the physiology and behavior of aquatic animals that rely on vision. In the guppy fish (Poecilia reticulata), a key element in the mating behavior and reproductive ...

Females that quickly and accurately locate and assess males can reduce their risks of predation, dehydration and heat stress while mate searching. Here we measured the accuracy and time it took female fiddler crabs, Uca ...

We describe the songs and courtship displays of three closely related hummingbirds, the Peruvian Sheartail (Thaumastura cora), Oasis Hummingbird (Rhodopis vesper), and the endangered Chilean Woodstar (Eulidia yarrellii). ...

Chemical cues play an important role in sexual recognition in several lizard species. Here, we investigated whether the neotropical lizard, Liolaemus pacha (Iguania: Liolaemidae) can discriminate between chemical information ...

We examine factors that influence male mating success in the glass frog Centrolene savagei; in addition, we describe courtship behaviour, oviposition and early parental behaviour. Fieldwork was conducted in the Colombian ...

Reproduction involves communication. Males usually evolve elaborate displays that may declare their qualities and attract females to mate, using signals from different modalities. Females may use cues encoded in courtship ...
