Blocking primer improves detection of tick-borne pathogens in Ixodes scapularis (black-legged ticks) from a Lyme disease hotspot region in eastern Ontario, Canada.

Sreevatshan K Srinivasan, Sima Afsharnezhad, Amber R. Paulson…·Robert I. Colautti

The paper introduces a blocking primer to improve detection of tick-borne pathogens in Ixodes scapularis ticks using 16S rRNA metabarcoding, achieving sensitivity comparable to qPCR and detecting additional pathogens.

Changes in sea ice alter genetic structure of an iconic Arctic apex predator in less than three decades

Sean N. Vanderluit, Marie‐Josée Fortin, Peter van Coeverden de Groot…·Stephen C. Lougheed

The paper shows that polar bear genetic structure changed significantly in the Canadian Arctic over two decades due to sea ice loss.
