ERGA-BGE reference genome of the Azores Bullfinch - Pyrrhula murina Godman, 1866: an IUCN Vulnerable Species endemic to a single island in the Azores Archipelago (Portugal)

TL;DR

This paper presents the first reference genome for the Azores Bullfinch, a vulnerable bird species found only on one island in the Azores.

Contribution

The study provides a high-quality chromosome-level genome assembly for Pyrrhula murina, enabling genetic monitoring and population analysis.

Findings

A chromosome-level genome assembly of 1.2 Gb was achieved with high contig and scaffold N50 values.

The genome includes 42 contiguous chromosomal pseudomolecules assembled from the sequence data.

The genome will help assess genetic diversity and population trends over time.

Abstract

Pyrrhula murina’s reference genome will substantially enhance the current monitoring of genetic diversity and population viability and will allow us to understand the effective population size trends throughout time and recent bottlenecks and population expansions. A total of 42 contiguous chromosomal pseudomolecules were assembled from the genome sequence. This chromosome-level assembly encompasses 1.2 Gb, composed of 65 contigs and 60 scaffolds, with contig and scaffold N50 values of 64.8 Mb and 76 Mb, respectively.
