Weak effects of a microsporidian parasite on mottled sculpin in Michigan streams

Despite the widespread occurrence of microsporidian parasites in vertebrates and many invertebrates, research regarding their effects on wild populations remains uncommon. We used several metrics of individual growth, condition, and population characteristics to evaluate the effects of a microsporidian infection (Glugea) on six infected populations of mottled sculpin (Cottus bairdii) compared w...

Les objets intermédiaires dans les activités d'ingénierie collaborative

The design process asks for strong collaborative activities among various disciplines with different know ledges and competences. The organization of collaborative design activities requires, at the early stages of design, a definition of mechanisms which allow exchanging preliminary (evolutional and not valid) information. When information is not validated or not available, they have to make d...

Juvenile coho salmon (Oncorhynchus kisutch) responses to salmon carcasses and in-stream wood manipulations during winter and spring

We investigated the growth rate, winter survival, presmolt size, and emigration timing of juvenile coho salmon (Oncorhynchus kisutch) in response to salmon carcasses and in-stream wood. Experimental trials were conducted during two consecutive years and pre-winter fish size and densities differed between years. Sixteen pens with emigration traps were built in a side-channel of the Mamquam River...
