Aboveground production efficiency and canopy nutrient contents of mixed-hardwood forest communities along a moisture gradient in the central United States
Autor: Andrew J. R. Gillespie, Shibu Jose
Publikováno v: Canadian Journal of Forest Research. 26:2214-2223
The significance of canopy nutrients in regulating aboveground production efficiency of mixed-hardwood forest communities (ecological land type phases, ELTPs) was examined along a moisture gradient in southern Indiana, U.S.A. A total of 39 plots were

The influence of mountain laurel on regeneration in pitch pine canopy gaps of the Coweeta Basin, North Carolina, U.S.A
Autor: Andrew J. R. Gillespie, James M. Vose, Jayson R. Waterman, Wayne T. Swank
Publikováno v: Canadian Journal of Forest Research. 25:1756-1762
Because of its dense nature, mountain laurel (Kalmialatifolia L.) understories may be retarding the regeneration of xeric pitch pine (Pinusrigida Mill.) sites in the southern Appalachians and thereby influencing successional dynamics. This study exam

Amount and vertical distribution of foliage of young loblolly pine trees as affected by canopy position and silvicultural treatment
Autor: James M. Vose, H. Lee Allen, Andrew J. R. Gillespie
Publikováno v: Canadian Journal of Forest Research. 24:1337-1344
Silvicultural practices such as thinning and fertilization can affect both canopy foliage quantity and distribution, altering stand growth. The objectives of this research were to quantify the effects of tree size and silvicultural treatment on the v

Publikováno v: Applied Physics Letters. 80:3009-3011
A table-top plasma focus device is shown to be an ideal neutron source for the calibration and characterization of dark matter detectors and has been optimized to produce a maximum yield of 2.0310 7 neutrons per shot. The interaction of energetic neu

Deletion of glycogen synthase kinase-3β in cartilage results in up-regulation of glycogen synthase kinase-3α protein expression
Autor: Frank Beier, S. Patel, James R. Woodgett, Veronica Ulici, J. R. Gillespie, H. Dupuis, A. DiMattia, A. Higgs
Publikováno v: Paediatrics Publications
The rate of endochondral bone growth determines final height in humans and is tightly controlled. Glycogen synthase kinase-3 (GSK-3) is a negative regulator of several signaling pathways that govern bone growth, such as insulin/IGF and Wnt/β-catenin

Tropical forest biomass estimation from truncated stand tables
Autor: Sandra Brown, Ariel E. Lugo, Andrew J. R. Gillespie
Publikováno v: Forest Ecology and Management. 48:69-87
Total aboveground forest biomass may be estimated through a variety of techniques based on commercial inventory stand and stock tables. Stand and stock tables from tropical countries commonly omit trees below a certain commercial limit, often ⩾ 35c
