Campioli, M., Samson, R., Michelsen, A., Jonasson, S., Baxter, R., Lemeur, R.
Abstract Bryophytes and lichens abound in many arctic ecosystems and can contribute substantially to the ecosystem net primary production (NPP). Because of their growth seasonality and their...
Fahy, M. P., Michelsen, A., Srinivasan, R., Creel, B., Brown, C., Sheng, Z.
Over the last five years, the Paso del Norte Watershed Council’s Coordinated Water Resources Database and GIS Project (Project) was developed to provide improved access to regional water resources...

Soil microbial biomass in arctic heaths has been shown to be largely unaffected by treatments simulating climate change with temperature, nutrient and light manipulations. Here, we demonstrate that...
Olsrud, M, Michelsen, A, Wallander, H
The relationship between ergosterol content in ericaceous hair roots and ericoid mycorrhizal (ErM) colonization versus dark septate endophytic (DSE) hyphal colonization was examined in a dwarf...
Response of ericoid mycorrhizal colonization and functioning to global change factors (2004)
Olsrud, M, Melillo, JM, Christensen, TR, Michelsen, A, Wallander, H, Olsson, PA
Here, we investigated effects of increased atmospheric CO2 concentration, increased temperatures, and both factors in combination on ericoid mycorrhizal colonization, mycorrhizal functioning and...
Falkengren-Grerup, U, Michelsen, A, Olsson, MO, Quarmby, C, Sleep, D
Our aim was to study whether the in situ natural abundance N-15 (delta(15)N)-values and N concentration of understory plants were correlated with the form and amount of mineral N available in the...
Cornelissen, J. H. C., Callaghan, T. V., Alatalo, J. M., Michelsen, A., Graglia, E., Hartley, A. E., ...
Macrolichens are important for the functioning and biodiversity of cold northern ecosystems and their reindeer-based cultures and economies. 2We hypothesized that, in climatically milder parts of the...

Nutrient availability is a major constraint to plant production and carbon storage in arctic ecosystems, but there are few studies coupling processes in the decomposer and microbial food web and the...
DoD Weapon Systems Software Management Study. Appendix C. Airborne Systems. (1998)
Bradshaw, J. F., Foard, T. R., Hazan, P. L., Ginsberg, H., Michelsen, A.
This appendix to the DoD Weapon Systems Software Management Study conducted by APL contains information on Airborne Systems presented in more detail than is given in the main report. The specific...
A new biophysical method to determine the gain of the acoustic trachea in bushcrickets (1994)
Michelsen, A., Rohrseitz, K., Stumpner, A.
Abstract A method is described for measuring the gain (i.e., the change of amplitude and phase angle) for sounds that propagate to the internal surface of the tympana in ears working as pressure...
EVALUATING THE EFFECTIVENESS OF CONSERVATION WATER-PRICING PROGRAMS
Huffaker, R., Whittlesey, N., Michelsen, A., Taylor, R., McGuckin, T.
Charging farmers increasing block prices for irrigation deliveries is advocated as a means of encouraging agricultural water conservation in the West. We formulated a model of a hypothetical...
