The optical dose in mJ/cm[superscript]2 for causing mortality of Escherichia coli, using wavelengths between 230-375 nm in the UV and 400-532 nm in the mid-visible spectral regions, has been determined in this study. ...

Resource-selection modelling techniques take either a deductive or inductive approach. Deductive methods take a “bottom-up” approach, where individual wildlife-resource relationships are the building blocks that define ...

This study documents sequence variation in three mitochondrial DNA (mtDNA) genes in the Yellow-billed Cuckoo {Coccyzus americanus) to re-examine the subspecies status of the western population (C.a. occidentalis). ...

Ecologists have paid considerable attention to how and why organisms select particular habitats. Of fundamental importance is discerning which physical factors of the environment restrict the occurrence of organisms to ...

Study area : Mackenzie River watershed, northeast of Thunder Bay, Northwestern Ontario (drains into Lake Superior)

If individuals base their patch and habitat choices on fine-scale differences in microhabitat, then their use o f patches, defined by capture sites, should correspond with measures o f microhabitat. But if individuals ...

Biomonitoring is a practice that has over time developed into a remarkably accurate form of detecting toxicity in the environment. The Toxicity Early Warning system (TEW) is a Real-Time Biomonitoring system developed to ...

The detection and identification of disease-causing parasites via DNA and the polymerase chain reaction (PCR) offers a new approach for quick and efficient disease diagnosis. Three nucleic acid based technologies have ...

Genetic profiling variations caused by tissue type, error, and damage have been studied only minimally in the past. Even though it is well accepted that damage to the DNA molecule and PCR induced error occur, little focus ...
