Using venom for predation often leads to the evolution of resistance in prey. Understanding
individual variation in venom resistance is key to unlocking basic mechanisms by which …

Population divergence through selection can drive local adaptation in natural populations
which has implications for the effective restoration of declining and extirpated populations …

Elevated temperatures resulting from climate change are expected to disproportionately
affect ectotherms given their biological function has a direct link to environmental …

Millions of wild animals in captivity are reared on diets that differ in their uptake and
composition from natural conditions. Few studies have investigated whether such novel …

Aquaculture practices continuously seek to improve efficiency to produce larger fish at lower
cost. Selective breeding within brood stocks can result in undesirable effects, promoting …

Chronic stress is a major source of welfare problems in many captive populations, including
fishes. While we have long known that chronic stress effects arise from maladaptive …

While outbreeding is a common method used to introduce variation to a broodstock in
aquaculture to maintain healthy genetic stocks, little consideration is given to identifying …

Alternative reproductive tactics are widespread in fishes. In Pacific salmon, males either
become a competitive hooknose, or a sneaker jack, which is undesirable in aquaculture …

In this thesis I explore the topic of maternal effects, and namely the effects of maternal stress
on various aspects of offspring phenotype. More specifically, I examine how chronically …

Triploid salmon–fish with three sets of chromosomes–are regularly used in aquaculture as
they are functionally sterile and therefore avoid the decline in flesh quality associated with …
