Sexual selection is often characterized by polygynous breeding systems, size dimorphism, and skewed operational sex ratios. Koalas are sexually dimorphic in multiple domains, yet are absent from the literature on sexual selection and the structure of their mating system is unclear. We provide the first documentation of the strength of sexual selection in koalas by using microsatellite markers to identify sires. We combine the genetic data with morphological data in order to assess the role of… 
Male-Biased Mate Competition in King Penguin Trio Parades
It is concluded that intrasexual selection in this colony follows the typical pattern of mate competition observed in species in which sexual dimorphisms and OSR are male biased, and the ultraviolet difference within the framework of the king penguins' colour perception is discussed.
Paternity in eastern grey kangaroos: moderate skew despite strong sexual dimorphism
Assessment of the distribution of paternities and quantified skew in male reproductive success in 2 populations of a marsupial with strong sexual dimorphism, the eastern grey kangaroos over 5 years suggests an unexpectedly low reproductive skew.

The Role of Bioacoustic Signals in Koala Sexual Selection: Insights from Seasonal Patterns of Associations Revealed with GPS-Proximity Units
It is concluded that indirect male-male competition, female mate choice, and possibly female competition, mediate sexual selection in koalas.
Disentangling the mechanisms of mate choice in a captive koala population
It is predicted that utilizing a variety of behavioral and MHC-dependent mate choice mechanisms improves female fitness through increased reproductive success and highlights the complexity ofmate choice mechanisms in a species.
Inbreeding and disease avoidance in a free‐ranging koala population
No evidence that female koalas can avoid mating with relatively more related available mates is found, which is concerning from a conservation perspective, as small, isolated populations may be at even higher risk of inbreeding depression than expected.
Movement of Free-Ranging Koalas in Response to Male Vocalisation Playbacks
Simple Summary Conservation management is critical for threatened wildlife species and an effective conservation approach relies on good understanding of animal behaviour in natural habitat.
Cues to body size in the formant spacing of male koala (Phascolarctos cinereus) bellows: honesty in an exaggerated trait
The findings show that the formant spacing of male koala bellows has the potential to provide receivers with reliable information on the caller's body size, and reveal that vocal adaptations allowing callers to exaggerate (or maximise) the acoustic impression of their size have evolved independently in marsupials and placental mammals.
Free-Ranging Male Koalas Use Size-Related Variation in Formant Frequencies to Assess Rival Males
The results indicate that male koalas invest more effort into their vocal responses when they are presented with bellows that have lower formants indicative of larger rivals, but also show that males are slower to engage in vocal exchanges with larger males that represent more dangerous rivals.


Sexual dimorphism and the mating ecology of polar bears (Ursus maritimus) at Svalbard
The wide range of male size in male-female pairs and the age-related signs of injury suggest that male polar bears engage in both scramble competition and contest competition for access to breeding females.
Variance in the male reproductive success of western gorillas: acquiring females is just the beginning
This study illustrates how a detailed analysis of the components of male reproductive success can shed light on the interrelated social and ecological aspects that affect it.
Female control : sexual selection by cryptic female choice
Cryptic female choice establishes a new bridge between sexual selection theory and reproductive physiology, in particular the physiological effects of male seminal products on female reproductive processes, such as sperm transport, oviposition, and remating.
Reproductive strategies of rhesus macaques
A common denominator to the reproductive strategies of both female and male rhesus macaques is that feeding patterns affect body condition which influences reproductive output and regulates relative reproductive success.
Mating patterns and reproductive success in captive koalas (Phascolarctos cinereus)
It is suggested that sexual selection regulates koala mating tactics primarily in the context of non-agonistic male competition and that field studies will reveal that females in the wild probably capitalize on the link between male vocal and olfactory advertisements and male age as a mechanism to foster positive assortative mating by age.
On the Opportunity for Sexual Selection, the Bateman Gradient and the Maximum Intensity of Sexual Selection

The meaning of Bateman's principles in the context of selection theory is considered, which provides a clearer focus on the important aspects of precopulatory sexual selection than other methods and therefore should be an important part of future studies of sexual selection.
Does body mass dimorphism increase male–female dietary niche separation? A comparative study of primates
There is some degree of dietary niche separation between the sexes of primates as body mass dimorphism increases, according to existing studies of intersexual niche separation.
Maternal effort and joey growth in koalas (Phascolarctos cinereus)
It is suggested that ecological and energetic constraints have moulded koala maternal strategies such that females maximize allocation of resources to offspring, regardless of sex, in order to increase prospects for joey survivorship.
