Intrasexual Selection: How Males Compete
Although modern sex roles acknowledge the fact that males and females both compete for and chose mates, there are sound theoretical reasons for...

Intrasexual cuticular hydrocarbon dimorphism in a wasp sheds light on hydrocarbon biosynthesis genes in Hymenoptera
Cuticular hydrocarbons (CHCs) cover the cuticle of insects and serve as desiccation barrier and as semiochemicals. While the main enzymatic steps of...

Body coloration as a dynamic signal during intrasexual communication in a cichlid fish
BackgroundIntrasexual competition over access to resources can lead to aggression between individuals. Because overt aggression, i.e. fights, can be...

Sexual Selection: Following Darwin’s Legacy
Much of the knowledge we treasure about evolution, and biology in general, rests on Darwin’s ideas about sexual selection put forward 150 years ago....

The Sexual Selection Landscape and Sexually-Selected Traits of the Crested Macaque (Macaca nigra)
Sexual selection explains the evolution of traits that impact mating and reproductive success. Primates are an excellent system for studying...

A new classification of mammalian uni-male multi-female groups based on the fundamental principles governing inter- and intrasexual relationships
Polygyny is the most common mating system in mammals, and many species form uni-male multi-female groups (UM-MF units). Polygynous systems are...

Social environment with high intrasexual competition enhances the positive relationship between faecal testosterone and cortisol metabolite levels in red deer
The relationship between reproductive and physiological stress hormones in vertebrates is poorly understood. In many species of mammals and...

Sexual selection leads to positive allometry but not sexual dimorphism in the expression of horn shape in the blue wildebeest, Connochaetes taurinus
Sexual selection is thought to be an important driver of adaptation, speciation and extinction. Empirically testing these predictions across...

Intrasexual variability of a conspicuous social signal influences attack rate of lizard models in an experimental test
Colorful sexual traits are shaped by the opposing pressures of natural and sexual selection. Although increased conspicuousness improves mating...

Sex in Killer Whales: Behavior, Exogamy, and the Evolution of Sexual Strategies in the Ocean’s Apex Predator
We present the current available knowledge about sexual behavior and mating systems in the killer whale, Orcinus orca, focusing primarily on the most...

The roles of sexual selection and sexual conflict in sha** patterns of genome and transcriptome variation
Sexual dimorphism is one of the most prevalent, and often the most extreme, examples of phenotypic variation within species, and arises primarily...

Conspecific scent marks may influence underground site selection by a fossorial reptile
AbstractConspecific cues often provide social information on habitat quality that is considered when deciding to settle at a specific site. The type...

Movement Patterns, Home Range and Habitat Selection of Australasian Marsupials
Knowledge of movement patterns, home range, and habitat selection is fundamental to understanding how species have adapted to their environments but...

Toward an understanding of the chemical ecology of alternative reproductive tactics in the bulb mite (Rhizoglyphus robini)
BackgroundUnder strong sexual selection, certain species evolve distinct intrasexual, alternative reproductive tactics (ARTs). In many cases, ARTs...

Habitat Selection and Space Use
This review provides support for the role of both macro- and micro-scale factors driving habitat selection by the little bustard. At a regional...

Androgens, antlers, and sexual selection: testosterone’s relationship to reproductive success and associated morphological characteristics in white-tailed deer
While hormones such as testosterone are known to drive reproduction and sexually selected traits in many species, research demonstrating a...

Socio-sexual behaviors and fecal hormone metabolites but not age predict female aggressive interactions in Macaca arctoides
AbstractThe role of androgens, age, and rank position in the regulation of intrasexual competition and aggression in primate males has been widely...

Sex-biased habitat selection by American marten in the Acadian Forest
ContextFor wildlife dependent on mature forest living in managed landscapes, habitat loss from land use can outpace habitat recovery from forest...

Behavioural Ecology of the Little Bustard: Sexual Selection and Mating Systems
In this chapter, we focus mainly on the behavioural ecology of the little bustard (i.e. how behaviour relates to ecology and evolution), with...
