Faulkner, S.G., Tonn, W.M., Schmitt, D.R., Welz, M.
Blasting in or near water can negatively affect fish. In Canada, there are maximum allowable limits for blasting-induced overpressure (100 kPa) and peak particle velocity (PPV; 13 mm/s) to protect fish and their incubating eggs, respectively. No studies, however, have related PPVs from blasting...

Life History Strategies in Extreme Environments: Comparative Demography of Arctic and Alpine Ptarmigan
Download2005
Hannon, S. J., Sandercock, B. K., Martin, K.
Abstract: Arctic and alpine habitats are extreme environments characterized by short breeding seasons, cold temperatures, limited food availability, and potentially high predation rates. Stringent ecological conditions are likely to have important consequences for the evolution of life history...

Mathematical modeling of nitrous oxide emissions from an agricultural field during spring thaw
Download1999
Confidence in regional estimates of N2O emissions used in national greenhouse gas inventories could be improved by using mathematical models of the biological and physical processes by which these emissions are known to be controlled. However these models must first be rigorously tested against...

Minimizing invasion risk by reducing propagule pressure: a model for ballast-water exchange
Download2005-01-01
Lewis, Mark A., Wonham, Marjorie J., MacIsaac, Hugh J.
Biological invasions are a major and increasing agent of global biodiversity change. Theory and practice indicate that invasion risk can be diminished by reducing propagule pressure, or the quantity, quality, and frequency of introduced individuals. For aquatic invasions, the primary global...

Moisture and temperature effects on survival and infectivity of first-stage larvae of Parelaphostrongylus odocoilei and P. tenuis (Nematoda: Metastrongyloidea).
Download1984
The survival of first-stage larvae (LI) of Parelaphostrongyluosd ocoilei and P. tenuis (Nematoda: Metastrongyloidea) and their infectivity to the snail Triodopsism ultilineata were determined experimentally in a variety of temperature and moisture conditions. Survival of larvae of P. odocoilei...

Movement and settlement patterns of animal offspring, along with the costs of occupying familiar and unfamiliar habitats, have been inferred frequently, but rarely have they been documented directly. To obtain such information, we monitored the individual fates of 205 (94%) of the 219 offspring...

Serpe, Michael J., Islam, Molla R.
In this submission we fabricated a humidity-responsive polymer-based actuator by layering negatively charged poly(N-isopropylacrylamide)-co-acrylic acid microgels and positively charged poly(diallyldimethyl ammonium chloride) on top of a flexible plastic substrate. We show that the extent of the...

Response of the Mediterranean Sea thermohaline circulation to observed changes in the winter wind stress field in the period 1980-1993
Download1999
Josey, Simon, Samuel, Sarah, Myers, Paul G., Haines, Keith
This paper seeks to model changes in deep water production in the eastern Mediterranean induced by changes in winter wind stress. An analysis of individual monthly wind stress fields over the Mediterranean for 1980–1993 from the SOC flux data set shows that an intensification of the winter mean...
