| comparison of sampling strategies for monitoring water quality in mesoscale canadian prairie watersheds. | the canadian prairies are subject to cold winter dynamics, spring snowmelt runoff, and summer storms; a process variability that makes it difficult to identify an adequate sampling strategy for capturing representative water quality data. hence, our research objective was to compare multiple water quality sampling strategies for prairie watersheds and rank them based on operational and statistical criteria. the focus was on the catfish creek watershed (manitoba, canada), which drains into the hy ... | 2015 | 26038319 |
| spinitectus macrospinosus n. sp. (nematoda: cystidicolidae) from the channel catfish ictalurus punctatus in southern manitoba and its distribution in other ictalurus spp. | spinitectus macrospinosus n. sp., a parasite of the channel catfish ictalurus punctatus, from the red and assiniboine rivers in southern manitoba, canada, is characterized by spines reaching a maximum length of 21.8-26.8 microm (means for males and females, respectively) in the anterior esophageal region, arranged in 4 sectors in the anterior region of the body. spines in this region of the body increase in size and decrease in number (from a maximum of 6 to 3 per sector). the combination of spi ... | 2003 | 14533691 |
