Nitrous oxide and methane production and emission in wetlands receiving nonpoint source nitrate loads

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Although wetland restoration is a promising strategy to reduce nonpoint source nitrogen (N) loads, there is some concern over the potential for increased nitrous oxide (N2O) emissions. We examined the production and emission of N2O and methane (CH4) from wetlands designed to intercept and reduce elevated, nonpoint source nitrate (NO3−) loads ...

Agricultural sustainability in the semi-arid Near East [PDF]

open access: yesClimate of the Past, 2007
Agriculture began in the eastern Mediterranean Levantine Corridor about 11000 years ago toward the end of the Younger Dryas when aridity had diminished wild food resources.

Mid‐Holocene drying of K'gari lakes (subtropical eastern Australia) necessitates re‐evaluation of the El Niño–Southern Oscillation climate links and future drying risk

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Holocene history of Australia's climate is surprisingly poorly understood. This is, in part, because of the relatively weak forcing of Holocene climate versus that of the late Pleistocene. However, it is commonly suggested that eastern Australia dried during the mid‐ to late‐Holocene and that this was in response to increased activity in ...

Nitrous oxide and nitric oxide fluxes differ from tea plantation and tropical forest soils after nitrogen addition

open access: yesFrontiers in Forests and Global Change
South Asia is experiencing a rapid increase in nitrogen (N) pollution which is predicted to continue in the future. One of the possible implications is an increase in gaseous reactive N losses from soil, notably in the form of nitrous oxide (N2O) and ...

Breeding home range selection of Eastern Population sandhill cranes across the boreal forest

open access: yesThe Journal of Wildlife Management, EarlyView.
We evaluated breeding home range habitat selection of sandhill cranes (Antigone canadensis) in the boreal forest of eastern Canada. Overall, we found that sandhill cranes selected breeding home ranges with greater proportions of wetlands, cropland, and recently disturbed forest.

Multiscale habitat analysis for the shoals spider lily: A species of conservation interest

open access: yesThe Journal of Wildlife Management, EarlyView.
We applied a multiscale analysis to determine what stream characteristics predicted shoals spider lily habitat in Stevens Creek, South Carolina. Shallow stream depth and coarse substrate were the most important predictors of spider lily presence at the microhabitat scale.

The importance of periodic droughts for maintaining diversity in the freshwater environment [PDF]

open access: yes, 1996
Whereas some species may rely on periodic drought conditions for part of their life histories, or have life strategies suited to exploiting the habitat or changed environmental conditions that are created by drought, for other organisms it is a time of ...
