Evolution: Radiotracking Sexual Selection
The development of sexual differences in body size in Odonata in relation to mating systems
TLDR
It is found that although larval differences in size may be present between the sexes, these are not necessarily shown in the adult stage (they may change or disappear), and the mating system was not related to patterns of adult SSD.
Mating system, male territoriality and agility as predictors of the evolution of sexual size dimorphism in hummingbirds (Aves: Trochilidae)
TLDR
It is suggested that evolutionary increases in male-biased SSD are related to increases in lekking behaviour and an allometric pattern for SSD consistent with Rensch’s rule is found that was not explained by estimates of male competition and agility.
Sexual size dimorphism in seabirds: sexual selection, fecundity selection and differential niche‐utilisation
TLDR
It is suggested that seabird SSD is most consistent with the sexual selection hypothesis via the agility of male displays, although further data and tests are required to establish whether different resource utilisation by males and females may also select for SSD.
Evolution of sexual size dimorphism in grouse and allies (Aves: Phasianidae) in relation to mating competition, fecundity demands and resource division
TLDR
The results are most consistent with the hypothesis that lekking behaviour led to the evolution of male‐biased SSD in Phasianidae.
Sexual Size Dimorphism in Hyla Savignyi Audouin, 1827 (Anura: Hylidae) from Nasiriyah Province, Southern of Iraq.
TLDR
There is a significant difference between genders in the frog of a tree population Hyla savignyi Audouin, 1827 (Anura: Hylidae), females larger than males.
Sexual selection on size and shape in Japanese beetles (Popillia japonica)
TLDR
Multivariate selection analyses support the prediction that smaller body size and larger wings in males benefit their mating success and partially explain the evolution of female-biased size dimorphism in this species.
Sexual selection, sexual size dimorphism and Rensch’s rule in Odonata
TLDR
The results suggest that sexual selection acting on male sizes influences SSD in Odonata, although this influence is modulated by territorial mating strategy and thus the likely advantage of being large.
Sexual selection on body size and secondary sexual characters in 2 closely related, sympatric chameleons in Madagascar
TLDR
Although difficult to determine the relative contributions of intra and intersexual selection on traits with dual benefits (both fighting and mate choice), both types of selection on body size and secondary sexual characters in these 2 chameleon species are documented.
Unusual allometry for sexual size dimorphism in a cichlid where males are extremely larger than females
TLDR
It is reported that the allometric relationship was negative across populations of a shell-brooding cichlid fish Lamprologus callipterus, although males are extremely larger than females, suggesting that females are more strongly subject to size selection associated with shell size availability than males.

SEXUAL SIZE DIMORPHISM IN SHOREBIRDS, GULLS, AND ALCIDS: THE INFLUENCE OF SEXUAL AND NATURAL SELECTION
TLDR
It is suggested that sexual selection has had a major influence on sexual size dimorphism in Charadrii, whereas divergence in the use of feeding resources while breeding was not supported by analyses.
Directional changes in sexual size dimorphism in shorebirds, gulls and alcids
TLDR
The results suggest that the observed variation in dimorphism of Charadrii can be best explained by male body size responding more sensitively to variable sexual selection than female body size.
Sexual selection explains Rensch's rule of size dimorphism in shorebirds.
Sexual size dimorphism shows a remarkably widespread relationship to body size in the animal kingdom: within lineages, it decreases with size when females are the larger sex, but it increases with…
Sexual size dimorphism in fallow deer (Dama dama): do larger, heavier males gain greater mating success?
TLDR
It is concluded that larger mature fallow bucks have advantages over other males when competing for matings, and sexual selection therefore continues to act on sexual size dimorphism in this species.
SEXUAL DIMORPHISM, MATING SYSTEM AND BODY SIZE IN NEW WORLD BLACKBIRDS (ICTERINAE)

  • 1992
TLDR
It is argued that it is inappropriate to assume that associations between a trait and body size or phylogeny are evidence of nonadaptive evolutionary “constraints,” and suggested that large body size itself, or the ecology of large species, promotes the development of coloniality and a polygynous mating system.
Male aerial display and reversed sexual size dimorphism in the dunlin
TLDR
During aerial display, small males also performed costly hovering flights more often and for relatively longer than large males, which support the aerial display hypothesis.
Female Moorhens Compete for Small Fat Males

  • 1983
Female moorhens in flocks competed with each other to obtain mates. The heaviest females won most of the agonistic encounters, and these females paired with males that had large fat reserves. Fat…
Sexual Dimorphism in Physiological Performance of Whiptail Lizards (Genus Cnemidophorus)
TLDR
Investigating physiological sexual dimorphism in the lizard genus Cnemidophorus by measuring whole‐animal traits, all of which are likely to influence fitness in these species: burst speed, endurance, maximal exertion capacity, standard metabolic rate, and evaporative water loss rate, revealed a strong trend toward higher absolute trait values in males for all variables except endurance.
A comparative study on the evolution of reversed size dimorphism in monogamous waders
TLDR
The analysis of wing shape showed that males of species with acrobatic flight displays had wings with higher aspect ratio than non-acrobatic species, which probably increases flight manoeuvrability during acrobotic displays.
Predicting the evolution of sexual size dimorphism
TLDR
The results suggest that genetic correlations constrain both the short‐term and long‐term evolution of SSD less than predicted by the Lande model.
