Morphological deformities in larvae of procladius skuse diptera chironomidae and their biomonitoring potential

, : Morphological deformities in larvae of procladius skuse diptera chironomidae and their biomonitoring potential. Canadian Journal of Fisheries & Aquatic Sciences 46(7): 1255-1270

Morphological deformities in Procladius larvae from sites in eastern and western Canada are described and compared. A framework for categorizing deformities in individual head capsule structures is presented to serve as a basis for indexing the severity of individual deformities and, eventually, to provide a more accurate measure of community response to contaminants. Comparison of morphological responses between Chironomus and Procladius suggest that Procladius is the more tolerant of environmental contaminants. It is proposed to use these differences in response to extend the range over which contaminant concentrations can be monitored.

The most common tracers used for lymphatic mapping in sentinel lymph node dissection (SLND) are blue dye and radio-colloid. The former is associated with hypersensitivity, and the latter is not available in some institutions. It is still unclear a...

Monolayer two-dimensional (2D) transition metal dichalcogenides (TMDs) show interesting optical and electrical properties because of their direct bandgap. However, the low absorption of atomically thin TMDs limits their applications. Here, we repo...
