Familie: Thraupidae – Tangaren
2020Nach der Auflistung von Winkler et al. (2015) und der Aktualisierung im HBW Alive (del Hoyo et al. 2019) werden die Tangaren aufgrund neuester molekularbiologischer Studien gegenwartig in 98 Gattungen und 377 Arten unterteilt. Damit sind sie eine der grosten Familien innerhalb der Passeriformes – und uberhaupt innerhalb der Aves.

Evidence of hybrid origin for Tachyphonus nattereri Pelzeln, 1870 (Aves: Thraupidae)
Zootaxa, 2017Tachyphonus nattereri is one of the three “mystery birds” collected almost 200 years ago by J. Natterer in Brazil whose validity has been disputed in many publications over the last century. Known only from the male holotype and perhaps a female specimen without type status, it is currently treated as either a valid species, a subspecies or a doubtful ...

Collection of Embryos from Darwin’s Finches (Thraupidae, Passeriformes)
Cold Spring Harbor Protocols, 2009INTRODUCTIONThere are no breeding colonies of Darwin’s finches anywhere in the world. Thus, all of the embryonic material is collected in the wild. This protocol describes how, in a field setting, fertilized eggs are collected and incubated at a precise temperature and how the resulting embryos are harvested and processed for in situ hybridization ...

The complete mitochondrial genome and phylogeny of Geospiza magnirostris (Passeriformes: Thraupidae)
Conservation Genetics Resources, 2018Geospiza magnirostris, an island species, was listed as of Least Concern (LC) on the IUCN Red List of Threatened Species; human entrapment, habitat destruction, predators, and competitors from the mainland have reduced its population. In this study, we first determined and described the complete mitochondrial genome of G.

A new species of tanager (Aves: Thraupidae) from the Eastern slopes of the Andes
ZootaxaThe Black-goggled Tanager (Trichothraupis melanops) is a South American forest species that comprises two disjunct populations in the Atlantic Forest and in the Andes. During visits to natural history museums, we noticed morphological differences between these populations, which led to a taxonomic revision of the species based on plumage patterns and ...

Evolution of Beak Size and Song Constraints in Neotropical Seedeaters (Thraupidae: Sporophila)
Acta Ornithologica, 2019Many traits influence birdsong diversity. Patterns observed in the acoustic parameters can be a result of morphological constraint and can also be explained by phylogenetic relationships. Understanding morphologic mechanisms that can act on song structure might account how they can catalyze speciation and how they evolve in lineages sort.

Molecular Phylogenetics and Evolution, 2015
The Neotropical ecoregion has been an important place of avian diversification where dispersal and allopatric events coupled with periods of active orogeny and climate change (Late Pliocene-Pleistocene) have shaped the biogeography of the region. In the Neotropics, avian population structure has been sculpted not only by geographical barriers, but also

Punctuated evolution of bill morphology in the largest family of songbirds (Thraupidae)
OrnithologyAbstract We assessed correlations between speciation rate and bill morphology in an ecologically diverse and continental-scale songbird radiation, the tanagers (Thraupidae). Our analyses showed that bill size, shape, and their evolutionary rates are not correlated with speciation rate.
