Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century
Fisheries Management and Ecology, EarlyView.ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

, 1997 We calculate the process $\gamma \gamma \rightarrow e^- \bar{\nu}_e u \bar{d}$ with the full set of Feynman diagrams. We consider different implementations of the $W$ width and different combinations of the photon polarisations.

International Journal of Modern Physics D, 2009 In quantum gravity, one seeks to combine quantum mechanics and general relativity. In attempting to do so, one comes across the "problem of time" impasse: the notion of time is conceptually different in each of these theories. In this paper, I consider the timeless records approach to resolving this.

ROBERT WALSER'S ‘BLEISTIFTWEG’: POETICS OF ATTENTION AS CRAFT
German Life and Letters, EarlyView.ABSTRACT This article examines Robert Walser's entry into what he called his ‘Bleistiftgebiet’ in the early 1920s, when in response to a profound crisis as a writer he began to produce manuscripts in minuscule size, the so‐called ‘Mikrogramme’ (microscripts). Intertwining the analysis of the short prose form with Walser's reflections on the short‐lived

New Phytologist, EarlyView.Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Theory and Practice of Logic Programming, 2007 AbstractWe present in this paper a general algorithm for solving first-order formulas in particular theories called decomposable theories. First of all, using special quantifiers, we give a formal characterization of decomposable theories and show some of their properties.
