Tb162: Red Maple And White Pine Litter Quality: Initial Changes With Decomposition, Mairin T. Delaney, Ivan J. Fernandez, Jeffrey A. Simmons, Russel D. Briggs
Technical Bulletins
The specific objectives of this study were (a) to define the organic and inorganic composition of foliar litter from red maple (Acer rubrum L.) and white pine (Pinus strobus L.), and (b) to determine the shifts in the organic and inorganic composition of these two litter types during the initial stages of decomposition. These two species were chosen because of their prominence in the northeastern U.S. and the contrast they afforded in litter quality characteristics which have a strong influence on litter decomposition.
Tb161: Forestry Investments And Option Values: Theory And Estimation, Andrew J. Plantinga
Tb161: Forestry Investments And Option Values: Theory And Estimation, Andrew J. Plantinga
Technical Bulletins
This bulletin considers option values related to a principal problem for forestry investors, the timing of harvests. The purpose is to present a general theory of the rotation problem under uncertainty and irreversibility and provide a methodology for empirically estimating option values. Modifications of the framework for analyzing options values related to other aspects of forestry investments are also discussed.

Tb160: The Horse Flies And Deer Flies Of Maine (Diptera, Tabanidae), L. L. Pechuman, Richard Dearborn
Technical Bulletins
The distribution of Maine Tabanidae is of special interest because of the number of species with more southern ranges which reach their northeastern limit in Maine. A few northern species reach their southern limit in the state. This paper includes all of the species known or likely to be found in Maine with specific localities by county for the more unusual species and for species not found throughout the state.
