The acoustic competition hypothesis predicts that song variability within a species will be
inversely correlated with the amount of acoustic competition from other species. To test this …

Breast cancer is the most common cancer among Canadian women and the second cause
of death from cancer. Fine needle aspirate (FNA) is a technology used to investigate early …
