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.

Assessment And Choice: An Operant Simulation Of Foraging In Patches, John P. Roche, D. Alan Stubbs, William E. Glanz

Biology and Ecology Faculty Scholarship

Pigeons were presented with an operant simulation of two prey patches using concurrent random ratio schedules of reinforcement. An unstable patch offered a higher initial reinforcement probability, which then declined unpredictably to a zero reinforcement probability in each session. A stable patch offered a low but unvarying reinforcement probability. When the reinforcement probability declined to zero in a single step, the birds displayed shorter giving-up times in the unstable patch when the ratio between the initial reinforcement probabilities in the unstable and stable patches was greater and when the combined magnitude of the reinforcement probabilities in the two patches was …

B846: Growing Season Parameter Reconstructions For New England Using Killing Frost Records, 1697-1947, William R. Baron, David C. Smith

Bulletins

In New England, killing frosts in the late spring and early fall mark the limits of the region's growing seasons. Over the years, farmers have tried to anticipate when to plant and when to harvest to safely prevent their crops from experiencing the harmful effects of freezing. As a hedge against failing memory, some farmers kept notes on when killing frosts occurred so that they could more readily calculate in the years to come when to sow and when to reap. Some of these notes have survived and are now preserved in archives and libraries across the region, or remain …

Mr400: Assessing Compliance With Bmps On Harvested Sites In Maine: Final Report, Russel D. Briggs, Alan J. Kimball, Janet Cormier

Miscellaneous Reports

The research was designed to help answer three questions: (1) What are the documented types of impacts on water quality from forestry activities in Maine? (2) Do timber harvesters use the best management practices recommended by the state to control water pollution? (3) Are these practices effective when they are used?

Mr399: Forestry-Related Nonpoint Source Pollution In Maine: A Literature Review, Craig Stafford, Mark Leathers, Russell Briggs

Miscellaneous Reports

A great deal of research effort has been devoted to the topic of erosion and sedimentation from forest lands. This report reviews the literature dealing with the potential sources of forestry-related nonpoint source pollution and impacts on surface water, with particular emphasis on those studies conducted in Maine and in the Northeast. This review is organized along the following topics: sediment, temperature, nitrate, phosphorus, acidity, and herbicides.

B843: The Ecology, Economics, And Management Of Potato Cropping Systems: A Report Of The First Four Years Of The Maine Potato Ecosystem Project, A. Randall Alford, Francis A. Drummond, Eric R. Gallandt, Eleanor Groden, David A. Lambert, Matt Liebman, Michele C. Marra, Jeffrey C. Mcburnie, Gregory A. Porter, Bacilio Salas

Bulletins

The bulletin reports on the first four years of the Maine Potato Ecosystem Project, a long-term, multidisciplinary study of alternative crop management strategies. The study site is a 15-acre tract on the northern boundary of the University of Maine's Aroostook Farm in Presque Isle, Maine, divided into 96 main plots that are grouped into four blocks. Each block is an area where soil survey data show similar soil characteristics. Thus, given the same production inputs, the crop output is expected to be the same on each plot within a block. Within each block there are 24 plots to which the …

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.

Charting A Course For The Future Of Maine's Fisheries: An Interview With Commissioner Robin Alden, Robin Alden

Maine Policy Review

In a January, 1996 interview, Commissioner of the Maine Department of Marine Resources, Robin Alden shared her concerns about the direction of federal fisheries management and her goals for building a more dynamic and self-managing system here in Maine. In particular, Alden described the recent legislation which creates zone councils and an apprenticeship system in Maine’s lobster fishery. Alden articulated a direction for Maine’s fisheries that challenges conventional fisheries management and as such, is being watched closely by fisheries managers in Maine as well as elsewhere in the U.S. and overseas.

Options For Managing Maine’S Fisheries: Fisheries Management From An Ecological Perspective, James A. Wilson

Maine Policy Review

Jim Wilson counters the concerns raised by Ralph Townsend [this issue].The current policy course set by Marine Resources Commissioner Robin Alden is based on an approach to fisheries management which redefines the sustainability problem as an ecosystem problem. Wilson argues that, within this new paradigm, questions such as “how, when, and where” to fish (or not fish) are much more central than species-specific quota setting. These questions not only change the rules under which co-management is implemented but also may improve fisheries management in ways that quota systems have failed, that is the long term conservation of species and habitats.

Clearcutting In Maine: Would Somebody Please Ask The Right Question?, John M. Hagan Iii

Maine Policy Review

In November [1996], Maine citizens will cast their votes for or against the Green Party-initiated referendum on forest practices. Better known as the clearcutting referendum, its supporters and opponents have staked out their terms in what has become a bitter debate over "jobs for Maine people" versus the "future of the Maine North Woods." Yet, amidst the deluge of media campaigns and ideological predictions, rest important questions—about forest management practices and how best to ensure a viable future for the people and forests of Maine. John Hagan contributes a perspective to this debate, blending scientific data with personal experience of …

Options For Managing Maine’S Fisheries: Traditional Fisheries Management, Ralph Townsend

Maine Policy Review

Ralph Townsend discusses the historic evolution of fisheries management as well as more current trends toward co-management in Maine’s groundfisheries. Looking at successful experiences with co-management, he wonders whether current efforts in Maine’s lobster industry will be successful without tackling the tough issue of access limitation.
