Outstanding, Ella Maltby!

Ella Maltby has received the St. Francis Xavier University Outstanding Graduate Research Award! Ella finished her MSc in fall 2021, and her research has been judged to be the top graduate work of the year. Here’s an excerpt from her nomination package:

Maltby’s thesis plays a crucially significant role in the science that will surround the complicated historical, societal, economic, and political issues related to Boat Harbour, its remediation, and the knock-on effects in both the fishing and forestry industries. Maltby’s first chapter surveyed contaminants at three different sites in Northumberland Strait, across three different age classes of lobsters.  Maltby found that overall, contaminant levels were low across the three sites and all age classes.  The only contaminant of concern was Arsenic, which, as has been found in a range of studies of both marine and terrestrial studies, tends to be elevated in and around Nova Scotia, linked to our underlying geology. Any future assessments of the effects of remediation of Boat Harbour will rely on Maltby’s baseline study as a comparison prior to remediation or prior to effluent release.

Maltby’s second chapter reports the first attempt at developing a behavioural bioassay for lobster.  Maltby found effects of the common contaminant Cadmium on several aspects of behaviour.  This proof of principle supports the notion that such behavioural bioassays could be used for future testing of pollutant effects on lobsters.  On the other hand, the relatively subtle behaviour effects combined with some effects on mortality, suggest that behaviours are relatively robust to the toxic effects of Cadmium at least, and thus there is a relatively narrow window in which behavioural effects could be detected before the pollutant becomes lethal. 

Congrats again Ella!
