Journal ArticleDOI
Disturbances and structural development of natural forest ecosystems with silvicultural implications, using Douglas-fir forests as an example
Jerry F. Franklin,Thomas A. Spies,Robert Van Pelt,Andrew B. Carey,Dale A. Thornburgh,Dean Rae Berg,David B. Lindenmayer,Mark E. Harmon,William S. Keeton,David C. Shaw,Ken Bible,Jiquan Chen +11 more
TL;DR: In this paper, the authors discuss the use of principles from disturbance ecology and natural stand development to create silvicultural approaches that are more aligned with natural processes, including the role of disturbances in creating structural legacies that become key elements of the post-disturbance stands.
Journal ArticleDOI
Cell stress-regulated human major histocompatibility complex class I gene expressed in gastrointestinal epithelium.
TL;DR: A highly divergent human MHC class I molecule, MICA, encodes a cell surface glycoprotein, which is not associated with beta 2-microglobulin, is conformationally stable independent of conventional class I peptide ligands, and almost exclusively expressed in gastrointestinal epithelium.
Journal ArticleDOI
Broad tumor-associated expression and recognition by tumor-derived γδ T cells of MICA and MICB
Veronika Groh,Rebecca Rhinehart,Heather Secrist,Stefan Bauer,Kenneth H. Grabstein,Thomas A. Spies +5 more
TL;DR: MICA/B are tumor-associated antigens that can be recognized, in an apparently unconditional manner, by a subset of tumor-infiltrating γδ T cells, and raise the possibility that an induced expression of Mica/B, by conditions that may be related to tumor homeostasis and growth, could play a role in immune responses against tumors.
Journal ArticleDOI
Light regimes beneath closed canopies and tree-fall gaps in temperate and tropical forests
Charles D. Canham,Julie S. Denslow,William J. Platt,James R. Runkle,Thomas A. Spies,Peter S. White +5 more
TL;DR: In this paper, the authors compared light regimes beneath closed canopies and tree-fall gaps for five temperate and tropical forests using fish-eye photography of intact forest canopie and a model for calculating light penetration through idealized gaps.
Journal ArticleDOI
Lidar Remote Sensing of the Canopy Structure and Biophysical Properties of Douglas-Fir Western Hemlock Forests
Michael A. Lefsky,Warren B. Cohen,S.A. Acker,Geoffrey G. Parker,Thomas A. Spies,David J. Harding +5 more
TL;DR: In this paper, a three-dimensional lock was developed to characterize the structural complexity of the forest canopy in moderate to high bioods of canopy description, which can be directly related to the indianalysis of lidar waveforms.
