  journal={Animal Behaviour},
Although postcopulatory displays are widespread in animals, little is known about their function or the intended receiver. The postcopulatory displays of dabbling ducks are among the best described for any animal group. We documented the presence of initial and additional postcopulatory displays in nearly all dabbling duck species. We then reconstructed the evolution of postcopulatory displays in dabbling ducks using a phylogeny derived from mitochondrial DNA sequences. The display immediately… 


The analysis revealed that many aspects of oropendola song are surprisingly evolutionarily conservative and thus are potentially useful characters for reconstructing historical patterns and suggest that complex vocalizations can provide information about phylogeny.

The evolution of social behaviour in sentinel crabs (Macrophthalmus): implications from molecular phylogeny

The analysis of fighting behaviour demonstrated that species with claw-extending fighting, being a more complex behaviour than grasping fighting, are found in the most ancestral part of the phylogeny, suggesting that fighting behaviour is not characterized by sufficient phylogenetic components.

Orgasm as a Post-Copulatory Display

This letter attempts to highlight several features of orgasm which are consistent with a Darwinian interpretation, and proposes that female and male sexual responses be considered together since orgasm and other components of sexuality derive from reproductive activities.

Female Goldeneye Ducks (Bucephala clangula) Do Not Discriminate among Male Precopulatory Display Patterns

It is suggested that there is not a correct sequence, or even a correct set of actions leading to copulation, in goldeneye species-specific precopulatory behavior as performed by adult males, although it apparently can be performed in a wide variety of patterns.

Response to interspecific vocalizations is affected by degree of phylogenetic relatedness in Streptopelia doves

This work tested the hypothesis that individuals are more responsive to signals from closely related species than from distantly related ones, and suggested a minor effect of sympatry, with the response to sympatric species being lower.

Hybridization patterns and the evolution of reproductive isolation in ducks

The authors' analyses of the number of interspecific crosses in relation to phylogenetic distance found a significant deviation between the observed and expected distribution of crosses controlling for the topology of the Anatinae phylogeny.

Phylogenetic analysis of non-stereotyped behavioural sequences with a successive event-pairing method

Non-stereotyped behaviour proved to be phylogenetically informative and to display low homoplasy, which opens an avenue for studying the evolution of behaviour in the framework of phylogenetic analysis, which was restricted until now to the study of stereotyped sequences and/or isolated features involved in courting or building activities.

Do forced extrapair copulations and interspecific brood amalgamation facilitate natural hybridisation in wildfowl

It is concluded that interspecific brood amalgamation has a stronger impact on natural hybridisation in wildfowl than forced extrapair copulations.


The size of the testes, the length of the intromittent organ, the height of the intrusions, the area covered by ridges and knobs increased significantly with the frequency of FEPC, and those relationships exist after correcting for common ancestry constraints.

Mating behaviour of the aphidophagous ladybird beetle Coelophora saucia (Coleoptera: Coccinellidae)

Results indicate that physical cues probably play a role in the initiation of courtship, while chemical signals are probably involved in the continuation of courtships, culminating in intromission in C. saucia.



Phylogeny and evolution of rodent copulatory behaviour

Phylogeny and biogeography of dabbling ducks (genus: Anas): A comparison of molecular and morphological evidence

It is suggested that the high dispersal ability of birds (especially dabbling ducks) has important implications for recovery of branches using molecular systematics and Geographic origin for most internal branches is ambiguous using several reconstruction methods.

A phylogenetic analysis and classification of recent dabbling ducks (Tribe anatini) based on comparative morphology

Cladistic analysis of 157 characters of definitive plumages and soft parts, natal plumages, tracheae, and nontracheal skeletons of 59 Anatini provided a phylogenetic hypothesis of high consistency and resolution and indicated that interspecific interfertility is a poor indicator of relationship.

Diversity and adaptation in rodent copulatory behavior

Detailed behavioral comparisons of a broad range of muroid species have revealed extensive behavioral diversity that was not anticipated from research confined to laboratory rats, and understanding of the adaptive significance of these behavioral patterns remains rudimentary.

Evolutionary trends in the behaviour and morphology of the Anatidae

The major evolutionary trends most clearly evident in the Anatidae are a trend from monomorphism to dimorphism in plumage, voice, voice and displays, and a trend towards the development of elaborate, often metallic-coloured, male plumage patterns and wing specula associated with displays that exhibit these patterns.

A phylogenetic analysis of recent anseriform genera using morphological characters

--A phylogenetic analysis of all Recent genera of the Anseriformes using 120 morphological characters supports much of the current consensus regarding intraordinal relationships. I found that (1)

Postinsemination Associations Between Males and Females in Insects: The Mate-Guarding Hypothesis

A major goal of evolutionary biologists is to identify the evolved function of particular traits. In developing hypotheses about the possible adaptive value of a characteristic of interest,

Copulatory patterns of primates as viewed in broad mammalian perspective

There are indications that variations in copulatory behavior are related to variations in genital morphology, and a tentative classification is proposed for 33 primate species.

Morphometrics of Flightlessness in the Alcidae

Analysis of skeletal measurements revealed that the genera of flightless Alcidae were characterized by relatively short distal wing elements and dorsoventral flattening of all major wing elements, in combination with relatively large core and pelvic dimensions, which were most pronounced in Mancalla.
