With climate change, scientists and others are interested in the future of Pacific salmon in the Arctic. Chum, pink, sockeye, coho, and chinook salmon have been encountered in the Beaufort Sea, well within Canadian Arctic waters. Chum is the only salmon species regarded as natal to the Mackenzie River watershed, although both pink and chum salmon appear to be natal to Alaska’s North Slope river...

Chirality is fundamental to chemistry, molecular biology and photonics, but chirality itself not often in the spotlight. Lewis E. MacKenzie Patrycja Stachelek report on 2021 Chiral Materials meeting, which explored how manifests functional materials, it can lead new technological applications.

Occupancy modeling is important for exploring species distribution patterns and for conservation monitoring. Within this framework, explicit attention is given to species detection probabilities estimated from replicate surveys to sample units. A central assumption is that replicate surveys are independent Bernoulli trials, but this assumption becomes untenable when ecologists serially deploy r...
