Estimating Population Abundance of Brook Trout: The Eleventh Hour

“The annual catch of brook trout and Atlantic salmon, however, is experiencing a relatively steady decline for a multitude of reasons; over-exploitation, habitat degradation, and the introduction of invasive species such as the smallmouth bass, for example, can account for some of this deterioration. In addition, brook trout are extremely sensitive to temperature-related stress and are intolerant to water temperatures above their thermal optima, which in general, is relatively low for salmonids.”

The Atlantic Canadian Roots of Nobel Laureate Dr. Arthur McDonald

“Nobel Laureate in physics Dr. Arthur McDonald has deep roots in Atlantic Canada. Born in Sydney, Nova Scotia, his passion for math and physics was instilled in him by his high school math teacher. By going out of his way to offer extra classes beyond the curriculum, this teacher was able to truly engage Dr. McDonald and other motivated classmates. Despite his clear affinity for mathematics, when Dr. McDonald went on to Dalhousie University for his undergraduate degree he was unsure of which science he intended to pursue. Another mentor, this time his first-year physics professor, showed Dr. McDonald the power of using mathematics as a tool for understanding and describing the universe. From here, Dr. McDonald embarked on a lifelong partnership with physics.“
