“…Habitat types were classi ed according to Tobias et al [69], complemented by Sigrist [70] and [71]: closed habitats include dense closed canopy forests, while semi-open habitats include environments such as open shrub forests, parks, forest dry, or dense savannah; in turn, open habitats include deserts, grasslands, undergrowth, rocky habitats, beaches, oceans, and cities. The extent of species distribution (km 2 ) was also compiled from Tobias et al [69].…”

BACKGROUND Several bird species involved in commercial trade of pets in Brazil, have presented occurrences outside their natural habitat, which may indicate possible introductions due to this activity. In this context we sought to evaluate the factors that influence the public’s interest in wild birds sold as pets in Brazil, and the relationship of those factors with new occurrences of birds outside their natural distribution area, discussing the relationship of commercial trade with possible introductions in new environments. METHODS We compiled the richness of bird species traded in Brazil and obtained comparative data of public interest directed to these species through the Google Trend tool. In addition, we gathered data on biological attributes and data on the sale price of the species in the trade, to analyze which factors would be related to public interest. New occurrences of birds outside their natural range were considered only if they were at a minimum distance of 800 km. Thus, factors related to public interest were then used to assess whether there was a relationship with these new occurrences. Data analysis was performed using Mixed Generalized Linear Models (GLMMs). RESULTS The results indicated that the public’s interest in certain species varies according to the region of the country, suggesting that the profile of interest in wild birds by people on the internet can be guided by sociocultural factors of each location. In addition, we found that the public interest is greater for songbirds, with generalist diet, which live in more open environments, have a greater distribution area and are sold at lower prices. All those factors, except for the distribution area, also showed to be related to the birds that presented new occurrences. CONCLUSIONS The public's preference for birds from more open and more generalist environments is probably the most important data, as such factors generally indicate greater environmental tolerance, which may favor the establishment of these birds in new environments. Thus, actions aimed at the conservation of commercialized species are essential to reduce the interregional trade of species, and consequently reduce the impact on natural populations and reduce the potential for new biological introductions.

“…From the literature, we also compiled information on the species' minimum and maximum elevations [51] (see the electronic supplementary material, table S9a for additional references). We combined the species' geographical distributions with their elevational range limits into range maps at the 2 arc-minute resolution [52].…”

“…Information on hummingbird habitat preferences was compiled by Stotz et al [51]. From this compilation, we categorized five different habitats: arid shrubland (arid lowland shrub and arid montane shrub), paramo-puna grasslands, humid highland (elfin forest, Polylepis woodland and humid montane shrub), cloud forest (montane evergreen forest), and humid lowlands (comprising all remaining lowland habitats).…”

Biodiversity cradles and museums segregating within hotspots of endemism

The immense concentrations of vertebrate species in tropical mountains remain a prominent but unexplained pattern in biogeography. A long-standing hypothesis suggests that montane biodiversity hotspots result from endemic species aggregating within ecologically stable localities. Here, the persistence of ancient lineages coincides with frequent speciation events, making such areas both ‘cradles’ (where new species arise) and ‘museums’ (where old species survive). Although this hypothesis refers to processes operating at the scale of valleys, it remains supported primarily by patterns generated from coarse-scale distribution data. Using high-resolution occurrence and phylogenetic data on Andean hummingbirds, we find that old and young endemic species are not spatially aggregated. The young endemic species tend to have non-overlapping distributions scattered along the Andean treeline, a long and narrow habitat where populations easily become fragmented. By contrast, the old endemic species have more aggregated distributions, but mainly within pockets of cloud forests at lower elevations than the young endemic species. These findings contradict the premise that biogeographical cradles and museums should overlap in valley systems where pockets of stable climate persist through periods of climate change. Instead, Andean biodiversity hotspots may derive from large-scale fluctuating climate complexity in conjunction with local-scale variability in available area and habitat connectivity.

“…Environment and/or habitat can influence multimodal signal evolution [5,23,24,26]; thus, to examine such effects in the context of woodpecker drum and colour evolution, we collected data for each species' primary habitat, as indicated by Stotz et al [62] and Del Hoyo et al [45]. We then classified these habitats in one of two broad categories-closed or open-which are thought to represent two extremes of the habitat continuum to which signalling strategies (visual and acoustic) are adapted [23,24].…”

Correlated evolution between colour conspicuousness and drum speed in woodpeckers

Sexual selection drives the evolution of many spectacular animal displays that we see in nature. Yet, how selection combines and elaborates different signal traits remains unclear. Here, we investigate this issue by testing for correlated evolution between head plumage colour and drumming behaviour in woodpeckers. These signals function in the context of mate choice and male–male competition, and they may appear to a receiver as a single multimodal display. We test for such correlations in males of 132 species using phylogenetic linear models, while considering the effect of habitat. We find that the plumage chromatic contrast is positively correlated with the speed of the drum, supporting the idea that species evolving more conspicuous plumage on their head also evolve faster drum displays. By contrast, we do not find evidence of correlated evolution between drum speed and head colour diversity, size of the head's red patch, or extent of the plumage achromatic contrast. Drum length was not correlated with any of the plumage coloration metrics. Lastly, we find no evidence that habitat acts as a strong selective force driving the evolution of head coloration or drumming elaboration. Coevolution between different signal modalities is therefore complex, and probably depends on the display components in question.
