Behavioural responses to heat in an arid-zone bird vary with thermal, hygric and social factorsNARA Subscribed
The severity of fitness costs resulting from behavioural trade-offs between heat dissipation and activities such as foraging is increasing with advancing climate change. In terrestrial habitats, shade and water may buffer individuals from the negative effects of heat exposure, as may load-lightening in group-living species. We tested the hypothesis that thermal and hygric properties of home ranges (shade and water availability...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Understanding the genetic diversity among accessions and germplasm is an important requirement for crop development as it allows for the selection of diverse parental combinations for enhancing genetic gain in varietal selection, advancement and release. The study aimed to characterize 183 provitamin A cassava ( Manihot esculenta Crantz) accessions and five Sierra Leonean varieties using morphological traits, total carotenoid...
A fixed‐dose approach to conducting emamectin benzoate tolerance assessments on field‐collected sea lice, Lepeophtheirus salmonisNARA Subscribed
In N ew B runswick, C anada, the sea louse, L epeophtheirus salmonis, poses an on‐going management challenge to the health and productivity of commercially cultured A tlantic salmon, S almo salar . While the in‐feed medication, emamectin benzoate ( SLICE ® ; M erck), has been highly effective for many years, evidence of increased tolerance has been observed in the field since late 2008. Although bioassays on motile stages are...
Sea lice monitoring on A tlantic salmon farms in N ew B runswick, C anada: comparing audit and farm staff countsNARA Subscribed
Sea lice audits were performed by the A tlantic V eterinary C ollege on commercial aquaculture sites in N ew B runswick, C anada, in 2011. Although the primary objective was to verify that farms were reporting similar lice counts to third‐party counts, more detailed comparisons were made to identify when lice counts were more likely to differ between the audit team and farm employees. A total of 28 sea lice audits were conduct...
