Introduction Noise pollution is a major stressor in the marine environment; however, responses of economically and ecologically important invertebrates, such as oysters, are largely unknown. Methods Under laboratory conditions, we measured acute behavioral and physiological responses of eastern oysters ( Crassostrea virginica) to sound treatments mimicking human activity in the environment. Results Oysters immediately reduced...

This study assessed the paternal effects on the growth of early juvenile winter flounder Pseudopleuronectes americanus and examined the energy allocation strategy employed during this critical stage. Males from three different locations (Passamaquoddy Bay, Baie‐des‐Chaleurs and the St Lawrence Estuary) were crossed with females from the Baie‐des‐Chaleurs, and the growth characteristics of hybrids from settlement to 45 days pos...

Nitrogen fertilization is considered as an important source of atmospheric N 2 O emission. A seven site‐year on‐farm field experiment was conducted at Ottawa and Guelph, ON and Saint‐Valentin, QC, Canada to characterize the affect of the amount and timing of N fertilizer on N 2 O emission in corn ( Zea mays L.) production. Using the static chamber method, gas samples were collected for 28‐days after preplant and 28‐days after...
