Comparative methods are often used to infer loss or gain of complex phenotypes, but few
studies take advantage of genes tightly linked with complex traits to test for shifts in the …

The limpet form–a cap-shaped or slipper-shaped univalved shell–convergently evolved in
many gastropod lineages, but questions remain about when, how often, and under which …

ABSTRACT The Upper Cretaceous (Coniacian-Santonian) of the Western Canada Foreland
Basin, contains a rich record of scaphitid ammonites (scaphites). We describe four species …

Abrupt environment changes can elicit an array of genetic effects. However, many of these
effects can be overlooked by functional genomic studies conducted in static laboratory …

Chemosensation detects environmental chemical cues and mediates many behaviors
directly related to fitness (eg finding food, mates). Mammals have a secondary …

This bulletin contains three closely integrated papers that treat Upper Cretaceous
(Coniacian-Santonian) strata of the Western Canada Foreland Basin (WCFB). Our research …
