ERGA-BGE Reference Genome of Loboptera subterranea: a cave adapted cockroach endemic to the Canary Islands

Species of the genus Loboptera from the Canary Islands are adapted to life in subterranean environments, except Loboptera canariensis and Loboptera decipiens which inhabit epigean, often influenced by human activities. The genome of Loboptera subterranea provides a valuable resource for understanding the genetic basis of how the Canarian Loboptera species evolved and thrived in subterranean environments. A total of 14 contiguous chromosomal pseudomolecules were assembled from the genome sequence. This chromosome-level assembly encompasses 2.7 Gb, composed of 486 contigs and 90 scaffolds, with contig and scaffold N50 values of 13.1 Mb and 202.7 Mb, respectively.

The reference genome of Androsace saussurei (Ericales: Primulaceae: Primuloideae) provides a valuable resource for understanding the mechanisms of plant adaptations to the most extreme environments where flowering plants can thrive and the speciation mechanisms of plants dwelling on high alpine sky islands. The entirety of the genome sequence was assembled into 20 contiguous chromosomal pseudomolecules. This chromosome-level assembly encompasses 413 Mb, composed of 253 contigs and 101 scaffolds, with contig and scaffold N50 values of 4.95 Mb and 21.2 Mb, respectively.

ERGA-BGE Reference Genome of Phyllidia flava (Nudibranchia: Phyllidiidae), a Relict Species Endemic to the Mediterranean Sea

Phyllidia flava, the only Mediterranean representative of the otherwise Indo-Pacific family Phyllididae, is a radula-less dorid nudibranch that feeds exclusively on toxic sponges, from which it derives defensive and camouflage compounds. Although not currently listed as endangered, this relict species remains vulnerable due to its restricted distribution and the rising temperatures of the Mediterranean Sea. A total of 13 contiguous chromosomal pseudomolecules were assembled, resulting in a chromosome-level genome spanning 1.9 Gb. This assembly comprises 2,032 contigs and 62 scaffolds, with contig and scaffold N50 values of 2.4 Mb and 169.7 Mb, respectively. This reference genome will serve as a valuable resource for conservation efforts, provide a robust calibration point for studying nudibranch phylogenetics based on the Tethys Ocean closure, and lay the groundwork for research into toxic prey diet specialisation.

ERGA-BGE Reference Genome of the Striped Field Mouse (Apodemus agrarius), a Widespread and Abundant Species in Central and Eastern Europe

The reference genome of Apodemus agrarius provides a valuable resource for phylogenetic studies of rodents, particularly mice, and for understanding factors that influence the geographical distribution of the species across East Asia and East Europe. A total of 25 contiguous chromosomal pseudomolecules were assembled from the genome sequence (23 autosomes and 2 sex chromosomes). This chromosome-level assembly encompasses 2.6 Gb, composed of 242 contigs and 60 scaffolds, with contig and scaffold N50 values of 35 Mb and 119 Mb, respectively.

ERGA-BGE Reference Genome of the Northern chamois (Rupicapra rupicapra): Europe's most abundant mountain ungulate

The reference genome of Rupicapra rupicapra (subsp. rupicapra) provides insights into the genetic makeup that enabled this iconic mountain ungulate to adapt to its harsh environment, including its ability to survive in extreme weather and high altitudes--factors that are increasingly important in the face of climate change. A total of 29 contiguous chromosomal pseudomolecules were assembled from the genome sequence. This chromosome-level assembly encompasses 2.62 Gb, composed of 124 contigs and 76 scaffolds, with contig and scaffold N50 values of 77 Mb and 101 Mb, respectively.

ERGA-BGE genome of Valencia hispanica (Valenciennes, 1826): a critically endangered Iberian toothcarp

The reference genome of Valencia hispanica, a critically endangered actinopterygian species endemic to the Iberian Peninsula, is key to unravelling its genetic architecture and adaptation to freshwater ecosystems. This genomic resource will enable targeted conservation efforts and shed light on the species essential role in ecological dynamics, including its contributions to algal biomass regulation and role in the aquatic food web while also highlighting the challenges it faces from habitat degradation and invasive species. Furthermore, it offers opportunities to gain valuable insights into the evolutionary paths within the Valenciidae family, significantly advancing our comprehension of genetic diversity and adaptability in aquatic ecosystems. The entirety of the genome sequence was assembled into 24 contiguous chromosomal pseudomolecules. This chromosome-level assembly encompasses 1.29Gb, composed of 99 contigs and 28 scaffolds, with contig and scaffold N50 values of 38.3Mb and 56.9Mb, respectively.

Introgression dynamics of sex-linked chromosomal inversions shape the Malawi cichlid adaptive radiation

Chromosomal inversions contribute to adaptive speciation by linking co-adapted alleles. Querying 1,375 genomes of the species-rich Malawi cichlid fish radiation, we discovered five large inversions segregating in the benthic subradiation that each suppress recombination over more than half a chromosome. Two inversions were transferred from deepwater pelagic Diplotaxodon via admixture, while the others established early in the deep benthic clade. Introgression of haplotypes from lineages inside and outside the Malawi radiation coincided with bursts of species diversification. Inversions show evidence for transient sex linkage and a striking excess of protein changing substitutions points towards selection on neuro-sensory, physiological and reproductive genes. We conclude that repeated interplay between depth adaptation and sex-specific selection on large inversions has been central to the evolution of this iconic system.

Reference genome sequence of the solitary bee Camptopoeum friesei Mocsary, 1894 (Hymenoptera, Andrenidae)

Bees are major pollinators of flowering plants and thus are important ecosystem service providers for natural habitats and crops. Evolution led to a wide range of adaptations in behaviors, morphology and ecological traits. Many plants rely on specialized bee species for pollination events, and so this interdependence can make them increasingly vulnerable to ongoing threats of habitat loss and pesticide exposure. Studying the genomes of bee species across different life histories and ecological specializations can help understand the evolution of these traits more generally, but also inform conservation efforts for Camptopoeum friesei specifically. Here, we present the reference genome of the solitary bee Camptopoeum friesei (Arthropoda; Insecta; Hymenoptera; Andrenidae). C. friesei is highly dependent on steppe habitats where it nests in saline soils. Further, it is highly specialized (oligolectic) on a few Asteraceae: Centaurea and Cirsium, in particular on Centaurea stoebe. As a consequence of its high specialization level, it is of its ecological niche with an extremely scattered and rare habitat, C. friesei is highly threatened in central Europe, albeit local aggregations can be rich in individuals. The high-quality genome assembly for the colourful bee Camptopoeum friesei was generated using long-read PacBio HiFi in combination with chromatin conformation capture (Hi-C) sequencing. The genome spans 367.7 megabases (Mb), N50 of 25.2 Mb. The majority of the assembly is scaffolded into 10 chromosomes and harbours [~]40% repeats.
