Landscape Planning and Conservation Biology: Systems Thinking Revisited
(Society for Conservation Biology, 2006)
The Riverside and Berwyn experience: Contrasts in landscape structure, perceptions of the urban landscape, and their effects on people
(Elsevier B. V., 2006)
Humans not only structure the landscape through their activities, but their perceptions of nature are affected by the spatial and temporal arrangements (structure) in the landscape. Our understanding of these interactions, ...
Meeting Public Expectations with Ecological Innovation in Riparian Landscapes
(American Water Resources Association, 2001)
Appearances matter for managing riparian landscapes because the appearance of landscapes affects public willingness to accept plans and designs that improve ecological quality. Riparian landscape design and planning should ...
Physical-Biological Coupling in Southern Lake Michigan: Influence of Episodic Sediment Resuspension on Phytoplankton
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-10)
The influence of episodic, sediment resuspension on phytoplankton abundance/volume and composition, the photosynthetic maximum rate (P B max ) and efficiency (α B ), and chlorophyll-specific growth (μ Chl ) was evaluated ...
Fine root chemistry and decomposition in model communities of north-temperate tree species show little response to elevated atmospheric CO 2 and varying soil resource availability
(Springer-Verlag, 2005-12)
Rising atmospheric [CO 2 ] has the potential to alter soil carbon (C) cycling by increasing the content of recalcitrant constituents in plant litter, thereby decreasing rates of decomposition. Because fine root turnover ...
Microbial community composition and function beneath temperate trees exposed to elevated atmospheric carbon dioxide and ozone
(Springer-Verlag, 2002-04)
We hypothesized that changes in plant growth resulting from atmospheric CO 2 and O 3 enrichment would alter the flow of C through soil food webs and that this effect would vary with tree species. To test this idea, we ...
Microbial Community Structure and Oxidative Enzyme Activity in Nitrogen-amended North Temperate Forest Soils
(Springer-Verlag; Spreinger-Verlag, 2004-10)
Large regions of temperate forest are subject to elevated atmospheric nitrogen (N) deposition which can affect soil organic matter dynamics by altering mass loss rates, soil respiration, and dissolved organic matter ...
Extracellular Enzyme Activities and Soil Organic Matter Dynamics for Northern Hardwood Forests receiving Simulated Nitrogen Deposition
(Kluwer Academic Publishers; Springer, 2005-08)
Anthropogenic nitrogen enrichment alters decomposition processes that control the flux of carbon (C) and nitrogen (N) from soil organic matter (SOM) pools. To link N-driven changes in SOM to microbial responses, we measured ...
Fine-root biomass and fluxes of soil carbon in young stands of paper birch and trembling aspen as affected by elevated atmospheric CO 2 and tropospheric O 3
(Springer-Verlag, 2001-07)
Rising atmospheric CO 2 may stimulate future forest productivity, possibly increasing carbon storage in terrestrial ecosystems, but how tropospheric ozone will modify this response is unknown. Because of the importance of ...
