Spotted owls (SOs, Strix occidentalis) are a flagship species inhabiting old-growth forests in western North America. In recent decades, their populations have declined due to ongoing reductions in suitable habitat caused by logging, wildfires, and competition with the congeneric barred owl (BO, Strix varia). The northern spotted owl (S.

This report assesses risk factors associated with mortality in patients presenting with COVID-19 infection and healthcare disparities.
Methods: We conducted a retrospective cohort study of consecutive patients presenting to emergency departments within an integrated health system who tested positive for COVID-19 between 7 March and 30 April 2020 in metropolitan Detroit.
Rationale: Transmitted resistance to integrase strand inhibitors (INSTI) has been uncommon, but is slowly becoming more prevalent among those living with HIV. In an era with 2-drug regimens for antiretroviral therapy, transmitted resistance for INSTI is alarming.
Patient Concerns: A 28-year-old African American female was recently diagnosed with HIV during a 30-week prenatal visit.
Importance: In late December 2019, an outbreak caused by a novel severe acute respiratory syndrome coronavirus 2 emerged in Wuhan, China. Data on the clinical characteristics and outcomes of infected patients in urban communities in the US are limited.
Objectives: To describe the clinical characteristics and outcomes of patients with coronavirus disease 2019 (COVID-19) and to perform a comparative analysis of hospitalized and ambulatory patient populations.
We used molecular data to assess the degree of genetic divergence across the breeding range of the orange-crowned warbler () in western North America with particular focus on characterizing the divergence between populations on the mainland of southern California and on the Channel Islands. We obtained sequences of the mitochondrial gene and genotypes at ten microsatellite data for 192 from populations spanning all four recognized subspecies. We recovered shallow, but significant, levels of divergence among populations across the species range.

We analyzed low-coverage, whole-genome sequence data from fifty-one barred and spotted owls to investigate recent introgression between these two species. Although we obtained genomic confirmation that these species can and do hybridize and backcross, we found no evidence of widespread introgression.

Methods: This retrospective chart review and telephone interview included patients with severe, refractory hidradenitis suppurativa treated with intravenous ertapenem between March 2013 and December 2016.
We report here the successful assembly of the complete mitochondrial genomes of the northern spotted owl () and the barred owl (). We utilized sequence data from two sequencing methodologies, Illumina paired-end sequence data with insert lengths ranging from approximately 250 nucleotides (nt) to 9,600 nt and read lengths from 100-375 nt and Sanger-derived sequences. We employed multiple assemblers and alignment methods to generate the final assemblies.

We generated Illumina paired-end sequence data at 90× coverage using nine libraries with insert lengths ranging from ∼250 to 9,600 nt and read lengths from 100 to 375 nt. The genome assembly is comprised of 8,108 scaffolds totaling 1.

Hybridization capture using restriction site-associated DNA probes (hyRAD) is a recently developed method for population genomics with museum specimens. The hyRAD method employs fragments produced in a restriction site-associated double digestion as the basis for probes that capture orthologous loci in samples of interest.

We collected two specimens in breeding condition in northwestern Sierra Norte de Chiapas, Mexico. Morphologic and genetic evidence support their identity as Elaenia frantzii.

The genome is 2,152 bp in length and is most similar (30 to 44.5% amino acid identity) to the genome sequences of other single-stranded DNA (ssDNA) circular viruses belonging to the gemycircularvirus group.
