Ecosystem Services from Forest Landscapes: Where We Are and Where We Go
No full textIn this chapter, we aim for three goals: 1. We summarize some key features from the chapters, as they pertain to the overall themes of the book. The chapters themselves provide great resources to bring awareness to some newer and broader aspects of forest ecosystem services as well as a literature-rich, synthetic approach to understanding these advances and future visions for related research and application. We will highlight some of those points here. 2. We then aim to provide some emerging messages resulting from these newer approaches to understanding the complexities of planning for, evaluating, and accentuating the FES. 3. Finally, we hope to provide some insights on science gaps, research priorities, and potentials for knowledge transfer mainly into practitioners and policy makers.Fil: Iverson, Louis R..

Rethinking the Term "Pi-Stacking"
No full textIt has become common to reference "pi-stacking" forces or "pi-pi interactions" when describing the interactions between neighbouring aromatic rings. Here, we review experimental and theoretical literature across several fields and conclude that the terms "pi-stacking" and "pi-pi interactions" do not accurately describe the forces that drive association between aromatic molecules of the types most commonly studied in chemistry or biology laboratories. We therefore propose that these terms are misleading and should no longer be used. Even without these terms, electrostatic considerations relating to polarized pi systems, as described by Hunter and Sanders, have provided a good qualitative starting place for predicting and understanding the interactions between aromatics for almost two decades. More recent work, however, is revealing that direct electrostatic interactions between polarized atoms of substituents as well as solvation/desolvation effects in strongly interacting solvents must also be considered and even dominate in many circumstances.Chemistr

Coupling between a glacier and a soft bed: II Model results
No full textAbstractThe relation between the local effective pressure and shear stress on till beneath Storglaciären, Sweden, discussed in Iverson and others (1999), provides an empirical basis for studying the processes that control the strength of the ice/bed coupling. Particles in the bed that protrude into the glacier sole support shear stresses that are limited by either ploughing or the traditional sliding mechanisms. Model calculations, based on studies of cone penetration through fine-grained sediment and sliding theory, agree with the observed relation between shear stress and effective pressure if the water layer at the ice/bed interface is assumed to thicken rapidly as the effective pressure approaches zero. Studies of the hydraulics of linked cavities provide support for this assumption, if the mean thickness of the water layer reflects the extent of microcavity development at the interface. Comparison of the calculated shear stress with the ultimate strength of till suggests that bed deformation limits the shear stress on till beneath Storglaciären only at intermediate effective pressures; at very low effective pressures, like those inferred at the site of the tiltmeter discussed in Iverson and others (1999), and at sufficiently high effective pressures, ploughing and sliding should focus motion near the glacier sole. A calculation using parameter values appropriate for Ice Stream B, West Antarctica, suggests that ploughing may occur there at shear stresses not sufficient to deform the bed at depth. This conclusion is reinforced by the likelihood that pore pressures in excess of hydrostatic should develop down-glacier from ploughing particles, thereby weakening the bed near the glacier sole. However, given the apparent sensitivity of the ice/bed coupling to basal conditions that may be highly variable, any blanket assumption regarding the flow mechanism of ice masses on soft beds should probably be viewed with skepticism.</jats:p
