Smaller beaks for colder winters: Thermoregulation drives beak size evolution in Australasian songbirds

et al. 2017

Birds' beaks play a key role in foraging, and most research on their size and shape has focused on this function. Recent findings suggest that beaks may also be important for thermoregulation, and this may drive morphological evolution as predicted by Allen's rule. However, the role of thermoregulation in the evolution of beak size across species remains largely unexplored. In particular, it remains unclear whether the need for retaining heat in the winter or dissipating heat in the summer plays the greater role in selection for beak size. Comparative studies are needed to evaluate the relative importance of these functions in beak size evolution. We addressed this question in a clade of birds exhibiting wide variation in their climatic niche: the Australasian honeyeaters and allies (Meliphagoidea). Across 158 species, we compared species' climatic conditions extracted from their ranges to beak size measurements in a combined spatial-phylogenetic framework. We found that winter minimum temperature was positively correlated with beak size, while summer maximum temperature was not. This suggests that while diet and foraging behavior may drive evolutionary changes in beak shape, changes in beak size can also be explained by the beak's role in thermoregulation, and winter heat retention in particular.

“…Among the oscine passerines, by far the largest radiation of birds, these resources are limited to five species from the Passerides clade. Yet the early evolution of the Oscines involved multiple branching in the Australo‐Papuan region in the Oligocene before the emergence of the Corvides and Passerides, the two groups that ultimately gave the oscines their numerical and ecological dominance (Marki et al, ; Oliveros et al, ). The superb fairy‐wren is an exemplar of the largest clade of that early radiation, the Meliphagides, which has almost 300 species.…”

The superb fairy‐wren, Malurus cyaneus, is one of the most iconic Australian passerine species. This species belongs to an endemic Australasian clade, Meliphagides, which diversified early in the evolution of the oscine passerines. Today, the oscine passerines comprise almost half of all avian species diversity. Despite the rapid increase of available bird genome assemblies, this part of the avian tree has not yet been represented by a high‐quality reference. To rectify that, we present the first high‐quality genome assembly of a Meliphagides representative: the superb fairy‐wren. We combined Illumina shotgun and mate‐pair sequences, PacBio long‐reads, and a genetic linkage map from an intensively sampled pedigree of a wild population to generate this genome assembly. Of the final assembled 1.07‐Gb genome, 975 Mb (90.4%) was anchored onto 25 pseudochromosomes resulting in a final superscaffold N50 of 68.11 Mb. This high‐quality bird genome assembly is one of only a handful which is also accompanied by a genetic map and recombination landscape. In comparison to other pedigree‐based bird genetic maps, we find that the fairy‐wren genetic map more closely resembles those of Taeniopygia guttata and Parus major maps, unlike the Ficedula albicollis map which more closely resembles that of Gallus gallus. Lastly, we also provide a predictive gene and repeat annotation of the genome assembly. This new high‐quality, annotated genome assembly will be an invaluable resource not only regarding the superb fairy‐wren species and relatives but also broadly across the avian tree by providing a novel reference point for comparative genomic analyses.

“…This is in strong contrast with closely related Malurus , where seasonal timing of acquisition of the male ornamental plumage is critical for female EP mate choice, and thereby for male reproductive success, due to very high EPP levels (Figure ). Because M. coronatus ' phylogenetic position is nested within this clade (Marki et al., ; Figure ), male breeding plumage in this species could represent a sexual trait formerly selected by female EP mate choice that underwent a shift in function, being subsequently selected by male–male competition. Alternatively, it is possible that breeding plumage elaboration ancestrally had a dual function, being used in both female choice and male–male competition (as may currently be the case in at least one species; Figure ), whereby the former function was lost as extreme EPP levels and female EP mate choice disappeared (see Kingma et al., ).…”

From ornament to armament or loss of function? Breeding plumage acquisition in a genetically monogamous bird

The evolution of conspicuous male traits is thought to be driven by female mate choice or male-male competition. These two mechanisms are often viewed as distinct processes, with most studies focusing on female choice. However, both mechanisms of sexual selection can act simultaneously on the same trait (i.e., dual function) and/or interact in a synergistic or conflicting way. Dual-function traits are commonly assumed to originate through male-male competition before being used in female choice; yet, most studies focusing on such traits could not determine the direction of change, lacking phylogenetic information. We investigated the role of conspicuous male seasonal plumage in male-male competitive interactions in the purple-crowned fairy-wren Malurus coronatus, a cooperatively breeding bird. Male breeding plumage in most Malurus species is selected by female choice through extra-pair mate choice, but unlike its congeners, M. coronatus is genetically monogamous, and females do not seem to choose males based on breeding plumage acquisition. Our study shows that, within groups, subordinate males that were older, and therefore higher-ranked in the queue for breeder position inheritance, produced a more complete breeding plumage. In line with this, subordinate males that were older and/or displayed a more complete breeding plumage were more successful in competitively acquiring a breeder position. A role as a signal of competitive ability was experimentally confirmed by presenting models of males: in breeding colours, these received more aggression from resident breeder males than in nonbreeding colours, but elicited limited response from females, consistent with competitors in breeding plumage being perceived as a bigger threat to the breeder male. The role of the conspicuous breeding plumage in mediating male-male interactions might account for its presence in this genetically monogamous species. As phylogenetic reconstructions suggest a past female choice function in M. coronatus, this could represent a sexual trait that shifted functions, or a dual-function trait that lost one function. These evolutionary scenarios imply that intra- and intersexual functions of ornaments may be gained or lost independently and offer new perspectives in understanding the complex dynamics of sexual selection.
