Lab will focus on the use of phylogenetic software and the analysis of molecular data sets. Lec/lab. PREREQS: (ST 351 [D-] or ST 351H [D-] ) and (ST 352* [D-] or ST 411* [D-] ) and (BI 311 [D-] or BI 311H [D-] or BI 445 [D-] )

Top BI 481 BIOGEOGRAPHY (3) 
Biogeography is the study of the distribution of biodiversity. We focus on abiotic (geological, climatological) and biotic (ecological, evolutionary) factors that govern diversity across space and through time, emphasizing assembly of communities, global change, and conservation in today’s rapidly changing world. The course format includes lecture, computer-based activities, and discussion. Offered winter term in odd years. PREREQS: BI 370 [D-] or BI 370H [D-]

Top BI 483 POPULATION BIOLOGY (3)  Offered in current or future terms
Theoretical and empirical views of the structure and function of populations from across the tree of life, emphasizing the integration of ecological and evolutionary approaches. Lec. PREREQS: (MTH 241 [D-] or MTH 251 [D-] or MTH 251H [D-] ) and (ST 351 [D-] or ST 351H [D-] ) and (ST 352* [D-] or ST 411* [D-] ) and (BI 311 [D-] or BI 311H [D-] or BI 370 [D-] or BI 370H [D-] )

Top BI 495 DISEASE ECOLOGY (3)  Offered in current or future terms
An introduction to disease ecology--the study of disease processes in natural populations and communities. The course focuses on (I) the role parasites play in the ecology and evolution of animal populations, including humans; and (II) the relevance of ecological and evolutionary considerations in managing infectious diseases. PREREQS: BI 370 [C-]

Top BI 498 SENIOR BIOLOGY FIELD TEST (0)  Offered in current or future terms
