Blue-crowned Manakin Sequence Assembly Release Notes Background: The blue-crowned manakin (Lepidothrix coronata) is a species of bird in the Pipridae family which ranges from the Pacific slope of Costa Rica to northwestern Ecuador and in western Amazonia from Venezuela, ... Colombia, Ecuador, Peru, Brazil to Bolivia. The males have a brilliant blue crown and a black body throughout much of its range, while in the subspecies found in southeastern Peru, southwestern Brazil and northern Bolivia males have a blue crown and green body (L. coronata caelestileata, regalis, exquisita); females of all subspecies are green. Relationships among the currently recognized 8 subspecies are not well understood. It's natural habitats are primarily tropical and occasionally subtropical moist forests (0-1350 m). Blue-crowned manakin males aggregate in leks, where they engage in competitive displays that may entice visiting females who are surveying prospective partners for copulation. Females appear to select males for mating based on both song and display rates, and often only one male within a given lek is reproductively successful. High reproductive skew among males has led to the question why males join leks when their chances of reproductive success are so low. Avian plumage traits are the targets of both natural and sexual selection. Consequently, genetic changes resulting in plumage variation among closely related taxa as in the blue-crowned manakin subspecies might represent important evolutionary events. The molecular basis of such differences in the blue-crowned manakin is an active area of research. The blue-crowned manakin DNA for shotgun sequencing is derived from an adult male (Lepidothrix coronata; B3197) from the genetic resources collection of the Louisiana State University Museum of Natural Science. Locality data for the voucher specimen (LSUMZ #110521) are as follows: Peru: Loreto Department; 1.5 km S Libertad, S. bank Rio Napo, 80 km N Iquitos. Total sequence genome input coverage on the Illumina HiSeq instrument was approx. 61x (41x fragments, 17x 3kb, and 3x 8kb) using a genome size estimate of 1Gb. The combined sequence reads were assembled using ALLPATHS-LG software (Gnerre et al 2011) and where possible, scaffold gaps were closed by mapping with 20X coverage of Illumina sequences and local gap assembly. Long insert reads were used to link assembled sequences into scaffolds using the program SSPACE (Boetzer 2011). This Lepidothrix coronata 1.0 version has been cleaned of contaminating contigs, and contigs 200bp and less were removed. The assembly is made up of a total of 4620 scaffolds (including single contig scaffolds) with an N50 scaffold length of 5.01Mb (N50 contig length is 142kb). The assembly spans 1.0.8Gb.
