Abstract* The eastern or Tasmanian bettong ( Bettongia gaimardi) is one of four extant bettong species and is listed as 'Near Threatened' by the IUCN. We sequenced short read data on the 10x system to generate a reference genome 3.46Gb in size and contig N50 of 87.36Kb. Additionally, we used GeMoMa to provide and accompanying annotation for the reference genome. The generation of a reference genome for the eastern bettong provides a vital resource for the conservation of the species.

We present a genome assembly of Tethysbaena scabra (Arthropoda; Crustacea; Malacostraca; Eumalacostraca; Peracarida; Thermosbaenacea; Monodellidae), a species endemic to Mallorca, Spain. The genome size is 1.18 gigabases that is scaffolded into 17 chromosomes plus a mitochondrial genome of 16,5 kilobases in length.

Streptomyces sp. BTA 1-131 was isolated from the marine sponge Melophlus sarasinorum collected in Indonesia. The crude extracts of this strain displayed antibacterial and cytotoxic activity, and therefore, to further investigate the bioactive potential of the strain, whole genome sequencing was performed in this study. The whole genome sequencing of Streptomyces sp. BTA 1-131 was conducted using both Illumina NextSeq and Oxford Nanopore platforms with a de novo hybrid assembly approach. The high-quality genome obtained is 10.23 Mbp with a GC content of 71.57%. It is organised into a single chromosomal contig, two linear plasmids, and one circular plasmid. Interestingly, a long-terminal inverted repeat (L-TIR) sequence of 1.5 Mbp has been confirmed in the strain genome. Phylogenomic analysis suggested that the strain BTA 1-131 likely represents a new species within the genus Streptomyces. To the best of our knowledge, the genome data described here would be the first report on the hybrid genome sequence of Streptomyces associated with the rarely reported sponge Melophlus sarasinorum from Indonesia, with a unique feature of L-TIR. The complete genome data generated here will provide compelling information for further analysis of the biosynthetic potential of the strain BTA 1-131 to produce new bioactive compounds.

The red-legged partridge ( Alectoris rufa ) is a socio-economically important game bird in southern Europe. Despite previous efforts, achieving a high-quality, chromosome-level genome assembly has remained challenging. Here, we present a de novo phased, gapless reference genome of A. rufa , combining Nanopore long-read sequencing and Hi-C data from both sexes. The assembly resolves 40 nuclear chromosomes (38 autosomes and the 2 sex chromosomes, Z and W) and the mitochondrial genome, achieving chromosome-scale resolution and 99.1% completeness based on the Aves BUSCO dataset. This high-quality genome provides a critical resource for studying genetic diversity, sex-linked traits, and evolutionary adaptations.

We present a genome assembly of Caretta caretta (the Loggerhead sea turtle; Chordata, Testudines, Cheloniidae), generated from genomic data from two unrelated females. The genome sequence is 2.13 gigabases in size. The assembly has a busco completion score of 96.1% and N50 of 130.95 Mb. The majority of the assembly is scaffolded into 28 chromosomal representations with a remaining 2% of the assembly being excluded from these.

Cinnamomum burmanni (Nees & T.Nees) Blume (Lauraceae) belongs to the Magnoliids group and is mainly distributed in Indonesia and Southeast Asia. The complete chloroplast (cp) genome of C. burmanni sampled from Indonesia was assembled and annotated for the first time in this study. The length of the cp genome is 152,765 bp with a GC content of 39%, and it consists of four subregions: a large single-copy (LSC) region of 93,636 bp, a small single-copy (SSC) region of 18,893 bp and two inverted repeats (IR) regions (IRA 20,121 bp; IRB 20,115 bp) . The cp genome of C. burmanni encodes a total of 173 unique genes, which are 96 protein-coding genes, 19 rRNA genes, and 68 tRNA genes that can be utilized for advanced genetic and genomic studies of the species.

In the Americas, the expansion in incidence of arboviral infections including Mayaro virus (MAYV) has drawn attention to the resurgence of viruses associated with understudied arthropods. Mosquitoes belonging to the genus Haemagogus are generally geographically restricted to the forests of Central and South America and the Caribbean and are the known sylvan vectors for yellow fever virus and emerging MAYV. With an established population in Jamaica, Haemagogus equinus has been reported to be well-adapted to oviposition in artificial containers close to human populations. Its role in arboviral transmission however is not fully understood. Given the dearth of genetic information and the difficulty in morphologically identifying cryptic features in species belonging to this genus, we report the first mitochondrial genome of Hg. equinus. Using a genome skimming approach, two Hg. equinus mosquito specimens were sequenced using the Illumina Novaseq 6000 platform. A representative mitogenome of 16,471 bp, 80.7% AT and 37 genes was assembled using NOVOplasty. Phylogenetic analysis placed Hg. equinus in the Albomaculatus section of the Haemagogus subgenus supporting previously described taxonomic studies.

We present a genome assembly from an individual female Lycaena helle (the Violet Copper; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The genome sequence is 547.31 megabases in span. The entirety of the genome sequence was assembled into 25 contiguous chromosomal pseudomolecules with no gaps, including the Z and W sex chromosomes. The mitochondrial genome has also been assembled and is 15.5 kilobases in length. Gene annotation of this assembly identified 20,122 protein coding genes.

Abstract* The swift parrot ( Lathamus discolor) is a Critically Endangered migratory parrot that breeds in Tasmania and winters on the Australian mainland. Here we provide a reference genome assembly for the swift parrot. We sequence PacBio HiFi reads to create a high-quality reference assembly and identify a complete mitochondrial sequence. We also generate a reference transcriptome from five organs to inform genome annotation. The genome was 1.24 Gb in length and consisted of 847 contigs with a contig N50 of 18.97 Gb and L50 of 20 contigs. This study provides an annotated reference assembly and transcriptomic resources for the swift parrot to assist in future conservation genomic research.

The Kroombit tinkerfrog ( Taudactylus pleione) is a stream-dwelling amphibian of the Myobatrachidae family. It is listed as Critically Endangered and is at high risk of extinction due to chytridiomycosis. Here, we provide the first genome assembly of the evolutionarily distinct Taudactylus genus. We sequenced PacBio HiFi reads to assemble a high-quality long-read genome and identified the mitochondrial genome. We also generated a global transcriptome from a tadpole to improve gene annotation. The genome was 5.52 Gb in length and consisted of 4,196 contigs with a contig N50 of 8.853 Mb and an L50 of 153. This study provides the first genomic resources for the Kroombit tinkerfrog to assist in future phylogenetic, environmental DNA, conservation breeding, and disease susceptibility studies.
