“…For instance, available phylogenies suggest that the closest relatives of birds specialized in WSE occupy extra-Amazonian biomes such as tepuis, Cerrado, Caatinga and Atlantic Forest (Capurucho et al 2013;Matos et al 2016;Crouch et al 2018;Ribas and Aleixo 2019). The ancestors of these species may have occupied white sand ecosystems in periods of expansion of this environment and, subsequently, may have experienced a period of isolation long enough to have become independent species (Gubili et al 2016;Capurucho 2020). Ecomorphological comparisons between specialist birds and their relatives from other environments may shed light on ecomorphological adaptations on a broader temporal scale than that adopted in the present study.…”

Birds that inhabit white-sand ecosystems (WSE) in the Amazon are adapted to habitats distributed as isolated patches. These environments occur in sandy soils that are extremely poor in nutrients, have low floristic diversity and support bird assemblages restricted to WSE. We investigated whether bird species specialized in WSE have morphological or ecological traits that distinguish them from generalist birds that share the same habitat but are not restricted to WSE. We collected morphological and ecological data from 22 specialist and 102 generalist bird species from WSE and described their ecomorphological diversity using multivariate analyses and measures of functional diversity. Understory insectivorous species that move alone or in pairs, were the group with the most species among specialist birds from WSE. In contrast, canopy frugivorous species that form mono- or heterospecific groups were more frequent among generalist species. Specialist and generalist birds overlapped extensively in ecomorphological space, with specialists occupying a narrower space compared to generalists. Functional diversity, however, was not different between specialist and generalist species when controlling for the number of species within the communities. Further studies comparing the ecomorphological diversity of bird assemblages of other environments in the Amazon may highlight the ecological pressures leading to the functional diversity of specialist species in WSE observed in this study.

“…Colour polymorphism has evolved repeatedly and independently in all major taxonomic groups. In several of these groups, such as birds, lizards, fish and insects, an increasing number of colour polymorphic species have been characterised in recent years (Gubili et al ., 2016; McLean et al ., 2017; Saenko et al ., 2019; Ahi et al ., 2020), providing the opportunity to examine similarities and differences in the processes generating and maintaining discrete phenotypic variation. Such comparisons can be especially powerful when polymorphism has evolved on multiple independent occasions within taxonomic groups, which share similarities in their basic biology (Roulin, 2004; Jamie & Meier, 2020).…”

Convergence and divergence in lizard colour polymorphisms

Colour polymorphic species are model systems for examining the evolutionary processes that generate and maintain discrete phenotypic variation in natural populations. Lizards have repeatedly evolved strikingly similar polymorphic sexual signals in distantly related lineages, providing an opportunity to examine convergence and divergence in colour polymorphism, correlated traits and associated evolutionary processes. Herein, we synthesise the extensive literature on lizard colour polymorphisms in both sexes, including recent advances in understanding of the underlying biochemical, cellular and genetic mechanisms, and correlated behavioural, physiological and life‐history traits. Male throat, head or ventral colour morphs generally consist of red/orange, yellow and white/blue morphs, and sometimes mixed morphs with combinations of two colours. Despite these convergent phenotypes, there is marked divergence in correlated behavioural, physiological and life‐history traits. We discuss the need for coherence in morph classification, particularly in relation to ‘mixed’ morphs. We highlight future research directions such as the genetic basis of convergent phenotypes and the role of environmental variation in the maintenance of polymorphism. Research in this very active field promises to continue to provide novel insights with broad significance to evolutionary biologists.

“…While the higher level phylogeny and taxonomy of manakins has received significant attention (also see Tello et al, 2009), work exploring intraspecific genetic variation within manakins has been restricted to relatively few species (e.g. Brumfield et al, 2008; Capurucho et al, 2013; Cheviron et al, 2006; Cheviron et al, 2005; Francisco et al, 2007; Gubili et al, 2016; Luna et al, 2017; McDonald, 2003; Reis et al, 2020).…”

AbstractThe complex landscape history of the Neotropics has generated opportunities for population isolation and subsequent diversification that place this region among the most species-rich in the world. Detailed phylogeographic studies are required to uncover the biogeographic histories of Neotropical taxa, to identify evolutionary correlates of diversity, and to reveal patterns of genetic connectivity, disjunction, and potential differentiation among lineages from different areas of endemism. The White-crowned Manakin (Pseudopipra pipra) is a small suboscine passerine bird that is broadly distributed through the subtropical rainforests of Central America, the lower montane cloud forests of the Andes from Colombia to central Peru, the lowlands of Amazonia and the Guianas, and the Atlantic forest of southeast Brazil. Pseudopipra is currently recognized as a single, polytypic biological species. We studied the effect of the Neotropical landscape on genetic and phenotypic differentiation within this species using genomic data derived from double digest restriction site associated DNA sequencing (ddRAD), and mitochondrial DNA. Most of the genetic breakpoints we identify among populations coincide with physical barriers to gene flow previously associated with avian areas of endemism. The phylogenetic relationships among these populations imply a novel pattern of Andean origination for this group, with subsequent diversification into the Amazonian lowlands. Our analysis of genomic admixture and gene flow establishes a complex history of introgression between some western Amazonian populations. These reticulate processes confound our application of standard concatenated and coalescent phylogenetic methods and raise the question of whether a lineage in the western Napo area of endemism should be considered a hybrid species. Lastly, analysis of variation in vocal and plumage phenotypes in the context of our phylogeny supports the hypothesis that Pseudopipra is a species-complex composed of at least 8, and perhaps up to 17 distinct species which have arisen in the last ∼2.5 Ma.
