Population ecology of landlocked Arctic charr, <i>Salvelinus alpinus L</i>., in the Canadian High Arctic
… of two distinct size modes, "Dwarf" and "Normal" charr, but with major differences both in size and relative numbers between the lakes. Tentative correlations between population structure, growth rate variation and possible genetic divergence are suggested by this fieldwork and the models …

The Light and Water Stress Tolerance of Two Invasive Legumes: <I>Cytisus scoparius</I> (Scotch broom) and <I>Spartium junceum</I> (Spanish broom)
… constraints on distributions of these plants. A reaction norm experimental design was used to determine growth and physiological responses of each to imposed conditions. Light treatments were stressful for both species. Increases in shade led to decreases in relative growth rates (RGR); however, …

Investigation into the potential invasiveness of the exotic Narrow-leaved Bittercress, (Cardamine impatiens L.), Brassicaceae
Exotic species often invade new areas and displace native species. The problems associated with such invasions are well known, but for many exotic species, experimental work has not yet been done to predict which, and under what conditions they may become a problem. Two greenhouse experiments were …

Genomic Selection, Quantitative Trait Loci and Genome-Wide Association Mapping for Spring Bread Wheat (Triticum aestivum L.) Improvement
… across-year genomic prediction using the reaction norm model, using a large TP size for making accurate genomic predictions, and not making across-population genomic predictions except for highly related populations.

Genetic and Environmental Modulation of the Chickpea - Mesorhizobium Symbiosis
Chickpea (Cicer arietinum) is a valuable crop grown worldwide. It fixes atmospheric nitrogen by establishing a symbiotic relationship with rhizobia and secretes organic acids from its roots and green tissues that play a role in interactions with beneficial microbes, insect herbivores, and …

Index selection in terminal sire sheep: implications for genetic improvement in a crossbreeding system
… traits were mostly above 0.8, indicating no GxE. Reactions norms for sires were fitted. For weight traits and UMD, sires had positive slopes (were environmentally sensitive) that were similar in value, thus performance improved with improving environments. For UFD, reaction norm slopes varied form …
