Bayesian models describing microhabitat associations of infrequently captured small mammals sampled under a complex hierarchical design

Creator:

Lam, Tzeng Yih and Maguire, Douglas A.

Abstract:

Knowledge about the relationship between habitat structure and abundance of a target species facilitates biodiversity conservation in managed forests. However, modeling the relationship for infrequent small mammal species in silvicultural experiments introduces the challenge of excessive zero counts and complex hierarchical sampling. A common solution has been to ignore infrequent...

Exploration of statistical methods for synthesizing the effects of variable-retention harvesting on multiple taxa

Creator:

Lam, Tzeng Yih

Abstract:

Variable-retention harvesting was proposed to reduce loss of biodiversity and ecosystem processes associated with late-seral Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest. The Demonstration of Ecosystem Management Options experiment was established to test this hypothesis. Analysis presents various challenges to drawing statistical inferences about treatment effects. This dissertation explored...
