Present and Future dendrochronological research in Lebanon.

The presentation will be an overview of Lebanon topography, climate, and forest types. It will discuss the different biop-climatic zones and forest types and species found in these zones. The forest products, services, and decline it will also be discussed. Finally, the presentation will focus on past, present, and future dendrochronological research in Lebanon.

Archaeology of “Empty Spaces” in the Southern Andes

The highlands of SW Bolivia, NW Argentina, and N Chile are the most arid part of the Andes. In this area, opportunities for human settlement concentrate in deep river valleys, piedmont oases, and to the lowest basins of the Altiplano (highplateau). This environmental structure has resulted in a long-term pattern of discontinuous settlement, with relatively small populations concentrated in favorable areas, separated by vast expanses of unpopulated mountain heights and deserts.

The Role of Invasive Earthworms as Ecosystem Engineers and the Associated Implications for Tree-Ring Research in the Great Lakes Region of North America

European earthworms have only recently been recognized as an invasive threat to the hardwood forests of the Great Lakes Region of North America, yet mounting evidence indicates that the invasion of earthworms into forests that had been earthworm-free since at least the last glacial maximum is profoundly and fundamentally altering nutrient cycling, soil structure, and the forest floor communities of these ecosystems. Less attention has been given to how earthworm invasions influence tree growth and productivity.
