Mandibles and labrum-epipharynx of tiger beetles: Basic structure and evolution (Coleoptera, Carabidae, Cicindelitae)
Download2011
Acorn, J. H., Ball, G. E., Shpeley, D.
Abstract: Using for comparison with, and as outgroups for, supertribe Cicindelitae, we describe and illustrate the mandibles and labrum-epipharynx of the basal geadephagans Trachypachus gibbsii LeConte, 1861 (family Trachypachidae), and family Carabidae: Pelophila rudis (LeConte, 1863)...

Mathematical modeling of nitrous oxide emissions from an agricultural field during spring thaw
Download1999
Confidence in regional estimates of N2O emissions used in national greenhouse gas inventories could be improved by using mathematical models of the biological and physical processes by which these emissions are known to be controlled. However these models must first be rigorously tested against...

Chang, S. X., Sidders, D., Jassal, R. S., Bhatti, J. S., Arevalo, C. B. M.
Abstract: This study compares soil respiration and its heterotrophic and autotrophic components in four land use types: agriculture, 2 and 9 year old hybrid poplar plantations, grassland, and a native aspen stand in north central Alberta, Canada, over a period of two growing seasons (2006 and...

Temperature sensitivity of N2O emissions from fertilized agricultural soils: Mathematical modeling in ecosys
Download2008
N2O emissions have been found to be highly sensitive to soil temperature (T-s) which may cause substantial rises in emissions with rises in Ts expected in most climate change scenarios. Mathematical models used to project changes in emissions during climate change should be able to simulate the...
