ALTERNATIVE male mating tactics are widespread among animal taxa1–3, but there are few well documented examples of genetic polymorphisms for them4–6. The dimorphism in male courtship behaviour between independent and satellite ruffs, Philomachm pugnax7,8 (a lekking sandpiper), has often been cited as a potential example but this has been questioned9,10 because of the lack of data11 and the widespread phenotypic plasticity in the development or expression of alternative tactics in other species1… 

The genetic polymorphism linked to mate-securing strategies in the male damselfly Mnais costalis Selys (Odonata: Calopterygidae)

By rearing two groups of larvae from the same female but sired by different male morphs, it is shown that differential morph development is genetically controlled and consistent with a single-locus two-allele autosomal genetic polymorphism.

A determines highly divergent male reproductive morphs in the ruff.

Novel behavioural, testes size, and steroid metabolic differences among morphs are described in Philomachus pugnax, a lek-breeding wading bird.

Structural genomic changes underlie alternative reproductive strategies in the ruff (Philomachus pugnax)

Using whole-genome sequencing, this work proposes an evolutionary scenario where the Satellite chromosome arose by a rare recombination event about 500,000 years ago and resolved the enigma of how such complex phenotypic differences can have a simple genetic basis.

Genetic mapping of the female mimic morph locus in the ruff

Two unlinked loci appear to control behavioural development in ruffs, and the Melanocortin-1 receptor (MC1R) gene is a candidate gene involved in alternative male morph determination in ruffed.

High frequency of polyandry in a lek mating system

The frequencies of polyandrous mating and multiple paternity in the ruff, a lekking shorebird with a genetic dimorphism in male mating behavior, are determined and active genetic diversification may apply with respect to the behavioral polymorphism.

Genetic interaction between male mating strategy and sex ratio in a marine isopod

Evidence is presented that two other factors—an autosomal gene, transformer (Tfr), and an extrachromosomal factor—interact with primary sex determination loci and with alleles at Ams, causing certain individuals to change sex, thereby biasing family sex ratios.

Evolutionary Ecology of Fixed Alternative Male Mating Strategies in the Ruff (Calidris pugnax)

This work focuses on the polymorphism of male mating strategies in the ruff, and proposes three lines of research avenues that will help to understand the eco-evolutionary dynamics of phenotypic differences within natural populations of this iconic model species.

Evidence for alternative male morphs in a Tanganyikan cichlid fish

Evidence is presented that Neolamprologus modestus males represent an alternative small-bodied male morph that may practice alternative reproductive tactics in this species, and that individuals may not change morphs within their lifetime, but instead may adopt distinct life history strategies.

The mechanisms of morph determination in the amphipod Jassa: implications for the evolution of alternative male phenotypes

The comparison of major and minor growth trajectories identified a heterochronic shift in maturation times between morphs, indicating that ecological selective pressures, rather than just sexual selection, may be involved in the maintenance of this conditional strategy.



Male polymorphism inLimia perugiae (Pisces: Poeciliidae)

Breeding experiments with the male-polymorphic poeciliid fish,Limia perugiae, a small teleostean endemic to the southeast of the Caribbean island Hispañola, can best be explained by a model of Y-linked genes for small and large size which are both suspended by the activity of an autosomal recessive repressor responsible for the development of intermediate males.

Behavioural dimorphism in male ruffs Philomachus pugnax (L.)

Arguments for the hypothesis that the status (independent or satellite) of an individual depends on genetical and environmental factors are presented, which suggests that males with independent plumages are homozygotes with respect to a particular gene, and that Males with satellite plumages represent the same condition but with alternative alleles.

Plumage color correlates with body size in the Ruff (Philomachus pugnax)

This chapter discusses adaptations for breeding in birds and the importance of certain assemblages of birds as information centres for food-finding within a Herring Gull colony.

Results from experiments designed to assess the relative importance of genetic and environmental factors as determinants of male horn morphology support recent theories on sexual selection which predict that male ornaments will evolve to be reliable indicators of male quality.

Paternal investment inversely related to degree of extra-pair paternity in the reed bunting

An exceptionally high proportion of extra-pair paternity is found in a wild population of reed buntings using single-locus DNA fingerprinting and it is proposed that males can assess their likelihood of paternity and adjust their nestling provisioning rates accordingly.

Phenotypic Plasticity and the Origins of Diversity

Much recent progress has been made toward integrating developmental and evolutionary biology, especially in vertebrate morphology, developmental genetics, and molecular biology, though an unfortunate one because it seems to imply that the main effect of developmental constraints is that of "Developmental constraints".

Canalization Versus Developmental Conversion in a Spatially Variable Environment

The results demonstrate that environmental control of development requires a cost to the stress-tolerant morphology, and suggest that a mixture of genetic and environmental control is an evolutionarily stable state under some conditions.

The Evolutionary Maintenance of Alternative Phenotypes

Polyphenism may be restricted to circumstances in which the developmental switch occurs during very early development, and the abundance of seasonal polyphenisms in multivoltine organisms suggests that where environments are favorable, developmental systems are often flexible enough for the establishment of simple polyphenism.
