Contiguous haplotype assemblies of Tigriopus aff. angulatus

Tigriopus copepods are found in splash pools on all seven continents from the equator to Arctic and Antarctic regions. Given their geographic distribution, frequent exposure to extreme environmental conditions in the high intertidal zone, and strong signatures of local adaptation, these copepods have become models for exploring patterns of stress tolerance and adaptation to stressful environments. However, most studies focus on a relatively small subset of Tigriopus species, and there are few genome resources representing the diversity of Tigriopus species and populations. We combined long-read, Pacific Biosciences HiFi data with short-read, Illumina HiC and RNA-seq data to assemble and annotate genome sequences representing a Tigriopus population collected from the coast of central Chile. The haplotypes that we assembled are placed into 12 major scaffolds (N50 18-19 Mbp, L50 6-7), equivalent to the number of chromosomes in other Tigriopus species. BUSCO and k-mer analyses of each haplotype and BUSCO analyses of gene models are relatively complete (95-99%) with respect to gene and k-mer content.
