The deep-sea environment is a sink for a wide variety of contaminants including heavy metals and organic compounds of anthropogenic origin. Life history traits of many deep-water fish species including longevity and high trophic position may predispose them to contaminant exposure and subsequent induction of pathological changes, including tumour formation....
Two myxozoan species were observed in the kidney of topsmelt, Atherinops affinis, during a survey of parasites of estuarine fishes in the Carpinteria Salt Marsh Reserve, California. Fish collected on 3 dates in 2012 and 2013 were sectioned and examined histologically. Large extrasporogonic stages occurred in the renal interstitium of...
Atrazine (ATZ) is a selective triazine herbicide used primarily for pre-emergent weed control in corn, sorghum and sugar cane production. It is one of the most widely used herbicides in North America. Some research published over the last decade suggests that chronic exposure to environmentally relevant ATZ concentrations can adversely...
Climate changes in the Pacific Northwest, USA, may cause both retreat of alpine glaciers and increases in the frequency and magnitude of storms delivering rainfall at high elevations absent significant snowpack, and both of these changes may affect the frequency and severity of destructive debris flows initiating on the region's...

Chronic heavy alcohol consumption is a risk factor for cortical bone fractures in males. The increase in fracture
risk may be due, in part, to reduced bone quality. Intracortical (osteonal) bone remodeling is the principle
mechanism for maintaining cortical bone quality. However, it is not clear how alcohol abuse impacts...
Fusarium crown rot (FCR) is one of the most widespread root and
crown diseases of wheat in the Pacific Northwest (PNW) of the United
States. Our objectives were to characterize crown rot severity and
distribution throughout the PNW by conducting a survey of 210 fields
covering the diverse dryland wheat-producing...
