Evolutionary ecology of breeding systems and life history: from individual to population responses in fish

点击翻译按钮获取中文摘要

A major challenge for ecologists and conservation biologists is to understand processes that shape variability among individuals and influence population abundances, particularly in response to natural and human-driven environmental change. The proposed research program explores these processes using Atlantic salmon, brown trout and Atlantic cod as model systems for experimental study. A range of approaches are involved, from controlled laboratory experiments to large-scale field experiments to molecular analyses that explore the expression of individual and population characteristics, particularly as they relate to reproduction. The aim is to more fully understand the linkages among reproductive behaviour, offspring success and the productivity of populations, and how this understanding may be applied to conservation biology and fisheries management.
