The object ive was to determine the ef fect iveness of a regular prescribed burning programfor reducing tree mortal i ty in southern pine forests burned by wi ldf ire . This s tudy was conducted on publ ic and industry lands in northeast Florida. On the Osceola National Forest, mean mortality was 3.5% in natural stands and 43% in plantations two growing seasons after u June 1998 wildfire. Burn ...

Maternal cytoplasmic inheritance may cause an upward bias in heritabili ty estimates from daughter on dam regression. Inaccurate evaluations of bulls or dams of future sires would result if such estimates were used in genetic evaluation. Expected genetic selection differential for bulls would be overestimated, but genetic gain would be little affected by incorrect heritabili ty estimates. Genet...

where p, q, e ∈ C t0,∞ , with p t > 0 and 0 < α ≤ β being constants. By a solution of 1.1 , wemean a function y t ∈ C1 Ty,∞ , , where Ty ≥ t0 depends on the particular solution, which has the property p t |y′ t |α−1y′ t ∈ C1 Ty,∞ and satisfies 1.1 . We restrict our attention to the nontrivial solutions y t of 1.1 only, that is, to solutions y t such that sup{|y t | : t ≥ T} > 0 for all T ≥ Ty ....
