Behavioural and hormonal aspects of the breeding ecology in sex-role reversed polyandrous birds
TLDR
It is suggested that males were unable to effectively guard their Christina Muck PhD Thesis 54 females to prevent extrapair paternity due to 1) the dense habitat they live in and 2) the onset of incubation before clutch completion.
Male-to-female testosterone ratios, dimorphism, and life history—what does it really tell us?
TLDR
The assumption that circulating testosterone should covary with ecologically relevant secondary sexual traits in females may be misleading: selection pressures on females differ from those on males and females may regulate behavior differently.
Testosterone in Females: Mediator of Adaptive Traits, Constraint on Sexual Dimorphism, or Both?
TLDR
It is hypothesized that sensitive traits could become subject to selection after a natural change in T and that traits with opposing fitness consequences in males and females could constrain dimorphism.

Aggression, Reproduction, and Androgens in Wild Dwarf Mongooses: A Test of the Challenge Hypothesis
TLDR
The challenge hypothesis states that as the breeding season commences, testosterone levels in essentially all species rise from a nonbreeding baseline to a slightly higher breeding baseline, and testosterone levels should rise to near the physiological maximum and remain highly elevated throughout he breeding season, which would facilitate behavior appropriate for male-male competition.
Experimental evidence of a testosterone-induced shift from paternal to mating behaviour in a facultatively polygynous songbird
TLDR
This study experimentally elevated T levels of monogamous males in the facultatively polygynous European starling, and compared mate attraction and paternal behaviour of T-treated males with those of controls (C-males).
Androgens and Mating Systems: Testosterone-induced Polygyny in Normally Monogamous Birds
TLDR
Data suggest strongly that the nature of avian mating systems is regulated proximately by temporal patterns of hormone secretion, and that, in monogamous males, plasma T is elevated only early in the season when territories and pair bonds are established, whereas, in polygynous forms, plasma levels of T are elevated for longer periods that may overlap the parental phase.
The "Challenge Hypothesis": Theoretical Implications for Patterns of Testosterone Secretion, Mating Systems, and Breeding Strategies
TLDR
This model indicates that there may be widely different hormonal responses to male-male and male-female interactions and presumably equally plastic neural mechanisms for the transduction of these signals into endocrine secretions.
DOES TESTOSTERONE AFFECT THE TRADE-OFF BETWEEN INVESTMENT IN SEXUAL/TERRITORIAL BEHAVIOUR AND PARENTAL CARE IN MALE GREAT TITS?
TLDR
It is discussed that the low overall responsiveness in the study might be related to a high fitness cost of neglecting offspring in favour of T-enhanced behaviour, which does not support the trade-off hypothesis.
Effects of Testosterone on Song, Aggression, and Nestling Feeding Behavior in Male Great Tits, Parus major
TLDR
The results suggest that vocal and physical aggression might be regulated differently in the great tit, and in contrast with most other studies on temperate bird species, T treatment did not affect male feeding rates.
Social modulation of androgen levels in male teleost fish.
Mating Season Aggression and Fecal Testosterone Levels in Male Ring-Tailed Lemurs (Lemur catta)
TLDR
Results suggest that the challenge hypothesis applies to mammals as well as to birds, reptiles, and fish, and elevations in testosterone were tightly circumscribed around days of estrus, suggesting a compromise between costs and benefits of elevated testosterone levels.
Evolutionary costs of aggression revealed by testosterone manipulations in free-living male lizards
TLDR
The natural plasmalevel of testosterone may be at an optimal level balancing any potential selection pressures for a higher level of testosterone through sexual selection with selection pressures through a lower level through a decrease in survivorship.
