Revisiting projected shifts in the climate envelopes of North American trees using updated general circulation models
(Blackwell Publishing LtdWiley Periodicals, Inc., 2011-08)
Global climate models are constantly being upgraded, but it is often not clear what these changes have on climate change impact projections. We used difference maps to directly compare downscaled projections of temperature ...
Diversity, abundance, and distribution of NO ‐forming nitrite reductase–encoding genes in deep‐sea subsurface sediments of the S outh C hina S ea
(Wiley Periodicals, Inc.ASM Press, 2013-03)
In marine ecosystems, both nitrite‐reducing bacteria and anaerobic ammonium‐oxidizing (anammox) bacteria, containing different types of NO ‐forming nitrite reductase–encoding genes, contribute to the nitrogen cycle. The ...
Chronic N deposition alters root respiration‐tissue N relationship in northern hardwood forests
(USDA Forest Service Research Note INT‐RN‐217Wiley Periodicals, Inc., 2012-01)
Specific root respiration rates typically increase with increasing tissue N concentration. As a result, it is often assumed that external factors inducing greater root N concentration, such as chronic N deposition, ...
Clarifying the landscape approach: A Letter to the Editor on “Integrated landscape approaches to managing social and environmental issues in the tropics”
(RoutledgeWiley Periodicals, Inc., 2017-11)
Range position and climate sensitivity: The structure of among‐population demographic responses to climatic variation
(Chapman and HallWiley Periodicals, Inc., 2018-01)
Species’ distributions will respond to climate change based on the relationship between local demographic processes and climate and how this relationship varies based on range position. A rarely tested demographic prediction ...
Groundwater shapes sediment biogeochemistry and microbial diversity in a submerged Great Lake sinkhole
(U.S. Environmental Protection AgencyWiley Periodicals, Inc., 2017-03)
For a large part of earth’s history, cyanobacterial mats thrived in lowâ oxygen conditions, yet our understanding of their ecological functioning is limited. Extant cyanobacterial mats provide windows into the putative ...
Atmospheric CO 2 and O 3 alter competition for soil nitrogen in developing forests
(U.S. Department of Agriculture Forest Service North Central Experiment Station, General Technical Report NC‐214Wiley Periodicals, Inc., 2012-04)
Plant growth responses to rising atmospheric CO 2 and O 3 vary among genotypes and between species, which could plausibly influence the strength of competitive interactions for soil N . Ascribable to the size‐symmetric ...
Soil fungal-arthropod responses to Populus tremuloides grown under enriched atmospheric CO 2 under field conditions
(Blackwell Science Ltd, 1997-12)
Composition of the early Oligocene ocean from coral stable isotope and elemental chemistry
(Blackwell Science Ltd, 2004-04)
A sectioned and polished specimen of the coral Archohelia vicksburgensis from the early Oligocene Byram Formation (∼30 Ma) near Vicksburg, Mississippi, reveals 12 prominent annual growth bands. Stable oxygen isotopic ...
No evidence that elevated CO2 gives tropical lianas an advantage over tropical trees
(DR W. Junk PublishersWiley Periodicals, Inc., 2015-05)
Recent studies indicate that lianas are increasing in size and abundance relative to trees in neotropical forests. As a result, forest dynamics and carbon balance may be altered through liana‐induced suppression of tree ...
