Haemosporidian parasites and incubation period influence plumage coloration in tanagers (Passeriformes: Thraupidae)
<p><span>Birds are visually oriented and use their plumage coloration as an important signaling trait in social communication. Males and females may have different patterns of plumage coloration, a phenomenon known as sexual dichromatism. Because males tend to have more complex plumages, sexual dichromatism is usually attributed to female choice. However, plumage coloration is partly condition-dependent, therefore other selective pressures affecting individuals' success may also drive the evolution of this trait. Here we used tanagers to study the relationships between dichromatism and plumage coloration complexity with parasitism by haemosporidians, investment in reproduction, and life-history traits. We screened blood samples from 2849 birds belonging to 52 tanager species for detecting haemosporidian parasites. We used publicly available data for plumage coloration, bird phylogeny, and life-history traits to run models with plumage dichromatism and complexity in males and females. We found that dichromatism was more pronounced in bird species with higher prevalence of haemosporidian parasites. Lastly, females with high plumage coloration complexity were associated with a longer incubation period. Our results indicate an association between haemosporidian parasites and plumage coloration suggesting that parasites impact mechanisms of both sexual selections, increasing differences between sexes, and social (non-sexual) selection, driving females to develop more complex colorations. </span></p>

Genetic confirmation of a hybrid between two highly divergent cardinalid species: A Rose-breasted Grosbeak (Pheucticus ludovicianus) and a Scarlet Tanager (Piranga olivacea)
<p><span>Using low-coverage whole-genome sequencing, analysis of vocalizations, and inferences from natural history, we document a first-generation hybrid between </span><span>a rose-breasted grosbeak (<em>Pheucticus ludovicianus</em>) and a scarlet tanager (<em>Piranga olivacea</em>). These two species occur sympatrically throughout much of eastern North America, although were not previously known to interbreed. Following the field identification of a putative hybrid, we use genetic and bioacoustic data to show that a rose-breasted grosbeak was the maternal parent and a scarlet tanager was the paternal parent of the hybrid, whose song was similar to the latter species. These two species diverged >10 million years ago, and thus it is surprising to find a hybrid formed under natural conditions in the wild. Notably, the hybrid has an exceptionally heterozygous genome, with a conservative estimate of a heterozygous base every 100 bp. The observation that this hybrid of such highly divergent parental taxa has survived until adulthood serves as another example of the capacity for hybrid birds to survive with an exceptionally divergent genomic composition.</span></p>

Hubbard Brook site, station 10-hectare bird count plot at Hubbard Brook Experimental Forest, study of animal abundance of Piranga olivacea (scarlet tanager) in units of numberPer10Hectares on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Hubbard Brook (HBR) contains animal abundance of Piranga olivacea (scarlet tanager) measurements in numberPer10Hectares units and were aggregated to a yearly timescale.

Data from: New insights into New World biogeography: an integrated view from the phylogeny of blackbirds, cardinals, sparrows, tanagers, warblers, and allies
Understanding the biogeographic origins and temporal sequencing of groups within a region or of lineages within an ecosystem can yield important insights into evolutionary dynamics and ecological processes. Fifty years ago, Ernst Mayr generated comprehensive—if limited—inferences about the origins of the New World avifaunas, including the importance of pre-Isthmian dispersal between North and South America. Since then, methodological advances have improved our ability to address many of the same questions, but the phylogenies upon which such analyses should be based have been incompletely sampled or fragmentary. Here, we report a near-species-level phylogeny of the diverse (~832 species) New World clade Emberizoidea—the group that includes the familiar sparrows, cardinals, blackbirds, wood-warblers, tanagers, and their close relatives—to our knowledge the largest essentially complete (≥95%) phylogenetic hypothesis for any group of organisms. Biogeographic analyses based on this tree suggest initial dispersal into the New World via Beringia, with rapid subsequent diversification, including early dispersal of 1 lineage (the tanagers, Thraupidae) into South America. We found substantial dispersal between North and South America prior to closure of the Isthmus of Panama, but with a notable increase afterward, with a directional bias from north to south. With much greater detail and historical rigor, these analyses largely confirm Mayr's speculations based on taxonomy, resolving outstanding ambiguity regarding the continental origins of some groups such as the Emberizidae and Icteridae. The phylogeny reported here will be a resource of broad utility for addressing additional evolutionary and ecological questions with this diverse group.

FIGURE 2. Maximum clade credibility trees reconstructed in BEAST for the core tanagers (Thraupinae) based on ND2 (A) and Cyt b (B) genes. While the ND2 topology indicates that Chlorospingus flavovirens is closely related to Bangsia arcaei, the Cyt b topology points to C. flavovirens as sister to all Bangsia species, although this relationship is weakly supported. For each node, the posterior probability from the BEAST analysis is given above the branch leading to that node, and the maximum likelihood value from the RAxML analysis is given below the branch. Nodes that lacked bootstrap support based on 1000 maximum-likelihood replicates are indicated by ''–''. Numbers in front on taxon names correspond to sample ID (see Supplementary file).
