PLoS ONE, 2020 Understanding the patterns of chemical exposure among biota across a landscape is challenging due to the spatial heterogeneity and complexity of the sources, pathways, and fate of the different chemicals.

Biosystems, 2021 The earliest record of animal life comes from the Ediacaran of Newfoundland, including dm scale fossil organisms, most of which are inferred to have been epibenthic immotile eumetazoans. This work introduces the palaeobiology of the major fossil groups in the Newfoundland assemblages including strange fractal-like taxa and addresses some of ...

Legacy DDT and its metabolites in Brook Trout from lakes within forested watersheds treated with aerial applications of insecticides. [PDF]
PLoS ONETo manage defoliation from insect outbreaks, about half of the forested land in New Brunswick, Canada, was treated with dichlorodiphenyltrichloroethane (DDT) between 1952 and 1968. Aerial applications of DDT have thus likely increased the risk of chronic

ARCTIC, 2015 Sediment cores from three lakes located in the northernmost region of Ungava, Quebec (Canada) were examined to define aquatic community and ecosystem variability during the Late Holocene period. A chironomid-based transfer function was used to reconstruct August air temperature trends, and lacustrine primary production was inferred from sedimentary ...

Environment International, 2012 Per- and poly-fluorinated compounds (PFCs), which include perfluorinated carboxylates (PFCAs) and sulfonates (PFSAs) and various precursors, are used in a wide variety of industrial, commercial and domestic products. This includes aqueous film forming foam (AFFF), which is used by military and commercial airports as fire suppressants.

Microplastics in the digestive tract of Gryllus pennsylvanicus crickets in a biosolid – treated agricultural field [PDF]
Scientific ReportsMicroplastic ubiquity, its general toxicology, and its suitability for ingestion by biota are leading ecological and human health concerns. Microplastics are abundant in terrestrial environments including agricultural settings where municipal biosolids ...

, 2014 In Ontario, standing trees are reserved to “lifeboat” organisms in harvested forests. I examined epiphytic lichen on residual trees in two natural and managed mixedwood forests. Effects of management intensity, tree species, diameter at breast height (DBH), elevation, and distance to landscape features were investigated on lichen species richness ...

The stratigraphic relationship between the Shuram carbon isotope excursion, the oxygenation of Neoproterozoic oceans, and the first appearance of the Ediacara biota and bilaterian trace fossils in northwestern Canada [PDF]
Chemical Geology, 2013 Abstract A mechanistic understanding of relationships between global glaciation, a putative second rise in atmospheric oxygen, the Shuram carbon isotope excursion, and the appearance of Ediacaran-type fossil impressions and bioturbation is dependent on the construction of accurate geological records through regional stratigraphic correlations.
