Shrub Encroachment Alters Sensitivity of Soil Respiration to Temperature and Moisture
Author(s):Cable, J. M.; Barron-Gafford, G. A.; Ogle, K.; Pavao-Zuckerman, M.; Scott, R. L.; Williams, David G.; Huxman, T. E.; Cable, J. M.; Barron-Gafford, G. A.; Ogle, K.; Pavao-Zuckerman, M.; Scott, R. L.; Williams, David G.; Huxman, T. E.
A greater abundance of shrubs in semiarid grasslands affects the spatial patterns of soil temperature, moisture, and litter, resulting in fertile islands with potentially enhanced soil metabolic activity. The goal of this ...
Reclassification of North American Haplopappus (Compositae : Astereae) Complete : Rayjacksonia Gen Nov
Author(s):Lane, M. A.; Hartman, Ronald L.; Lane, M. A.; Hartman, Ronald L.
Rayjacksonia R. L. Hartman & M. A. Lane, gen. nov. (Compositae: Astereae), is named to accommodate the ''phyllocephalus complex,'' formerly of Haplopappus Cass. sect. Blepharodon DC. The new combinations are R. phyllocephalus ...
Protein Use and Muscle-Fiber Changes in Free-Ranging, Hibernating Black Bears
Author(s):Tinker, Daniel B.; Harlow, H. J.; Beck, T. D. I.; Tinker, Daniel B.; Harlow, H. J.; Beck, T. D. I.
Studies of the metabolic and physiological changes that bears undergo during hibernation have, for the most part, supported the paradigm that bears use only fatty tissues as a metabolic substrate during hibernation. This ...

Author(s):Brown, Gregory K.; Gilmartin, A. J.; Brown, Gregory K.; Gilmartin, A. J.
Meeting abstract of "Chromosome numbers in Bromeliaceae" in American Journal of Botany, 1986, presented at the Annual Meetings of the Botanical Society of America.
On the Representativeness of Plot Size and Location for Scaling Transpiration from Trees to a Stand
Author(s):Mackay, D. S.; Ewers, Brent E.; Loranty, M. M.; Kruger, E. L.; Mackay, D. S.; Ewers, Brent E.; Loranty, M. M.; Kruger, E. L.
Scaling transpiration from trees to larger areas is a fundamental problem in ecohydrology. For scaling stand transpiration from sap flux sensors we asked if plot representativeness depended on plot size and location, the ...
