Genomic Studies

Northern cardinals (Cardinalis cardinalis) are common, mid-sized passerines widely distributed in North America. As an iconic species with strong sexual dichromatism, it has been the focus of extensive ecological and evolutionary research, yet genomic studies investigating the evolution of genotype–phenotype association of plumage coloration and dichromatism are lacking. Here we present a new, highly-contiguous assembly for C. cardinalis. We generated a 1.1 Gb assembly comprised of 4,762 scaffolds, with a scaffold N50 of 3.6 Mb, a contig N50 of 114.4 kb and a longest scaffold of 19.7 Mb. We identified 93.5% complete and single-copy orthologs from an Aves dataset using BUSCO, demonstrating high completeness of the genome assembly. We annotated the genomic region comprising the CYP2J19 gene, which plays a pivotal role in the red coloration in birds. Comparative analyses demonstrated non-exonic regions unique to the CYP2J19 gene in passerines and a long insertion upstream of the gene in C. cardinalis. Transcription factor binding motifs discovered in the unique insertion region in C. cardinalis suggest potential androgen-regulated mechanisms underlying sexual dichromatism. Pairwise Sequential Markovian Coalescent (PSMC) analysis of the genome reveals fluctuations in historic effective population size between 100,000–250,000 in the last 2 millions years, with declines concordant with the beginning of the Pleistocene epoch and Last Glacial Period. This draft genome of C. cardinalis provides an important resource for future studies of ecological, evolutionary, and functional genomics in cardinals and other birds.

AbstractA 6.5-year-old female bearded dragon (Pogona vitticeps) was presented with a swollen right pelvic limb. A tissue core biopsy from the swollen area was performed and a presumptive histopathological diagnosis of adenocarcinoma was made. This diagnosis was confirmed after limb amputation. Two months after amputation a sudden deterioration in the overall health of the patient occurred. Ultrasound examination of the coelomic cavity revealed hypoechoic lesions in the liver. The patient was euthanized and submitted for necropsy which revealed a severely enlarged liver with multiple coalescing yellowish nodules. Cholangiocarcinoma of the liver with metastases to the spleen, left mesovarium and right pelvic limb was diagnosed after histopathological examination.

AbstractSix species of the syringophilid mites belonging to the genus Syringophiloidus Kethley, 1970 (Acari, Prostigmata) are recorded from eight avian hosts from USA. Four new species are described and illustrated: S. molothrus sp. nov. from the Brown-headed Cowbird Molothrus ater (Boddaert) (Passeriformes, Icteridae), S. carolae sp. nov. from the Acorn Woodpecker Melanerpes formicivorus (Swainson) (Piciformes, Picidae) and from the Northern Cardinal Cardinalis cardinalis (Linnaeus) (Passeriformes, Cardinalidae), S. sialius sp. nov. from the Western Bluebird Sialia mexicana Swainson (Passeriformes, Turdidae), and S. thryothorus sp. nov. from the Carolina Wren Thryothorus ludovicianus (Latham) (Passeriformes, Troglodytidae). The previously described species S. motacillae Bochkov et Mironov, 1998 is new for USA. Two host species, the American Robin Turdus migratorius Linnaeus (Turdidae) and the Steller’s Jay Cyanocitta stelleri (Gmelin) (Passeriformes, Corvidae), are new for S. presentalis Chirov et Kravtsova, 1995.
