Seaweed‐associated microbes are the metabolic heavy lifters in the symbiotic relationship between the seaweed microbiome and their host macroalgae. In exchange for fixed carbon and an exclusive niche habitat offered by the host, the microbial consort performs a litany of crucial metabolic functions including vitamin production, nitrogen fixation, growth and reproductive signalling, pathogen resistance and mitigation of environ...

Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) may occur at least 10 years before a clinical diagnosis of an α-synucleinopathy, such as dementia with Lewy bodies (DLB), Parkinson’s disease (PD) or multiple system atrophy (MSA). The extent to which people with iRBD manifest subtle features of these conditions is an area of active research and whether these changes can be measured remotely in the community is a...

Gait and key-tapping are individually associated with mild cognitive impairment (MCI) and dementia. However, it is unclear if these motor functions are correlated, or whether combining them improves classification of objective (dementia, MCI) and subjective cognitive impairment (SCI). We recruited 73 participants with dementia, 106 MCI, 57 SCI, and 83 cognitively healthy controls (HC). Consensus diagnosis was made after gold-s...

Theory suggests that animals make hierarchical, multiscale resource selection decisions to address the hierarchy of factors limiting their fitness. Ecologists have developed tools to link population‐level resource selection across scales; yet, theoretical expectations about the relationship between coarse‐ and fine‐scale selection decisions at the individual level remain elusive despite their importance to fitness. With GPS‐te...

Marine reservoir age is reported for Foxe Basin, Canada, during deglaciation of the Laurentide Ice Sheet. Radiocarbon ( 14 C) measurements were made on pairs of contemporaneous molluscs and Salix (willow) macrofossils, yielding a mean marine reservoir age of 985 ± 10 14 C a. Mean regional Δ R is calculated to be 615 ± 20 14 C a relative to a mean global reservoir age of ca. 400 14 C a. Previous studies in the Canadian Arctic t...
