Effect of simulated emerald ash borer infestation on nitrogen cycling in black ash (Fraxinus nigra) wetlands in northern Minnesota, USA

Black ash (Fraxinus nigra) wetlands are an important economic, cultural, and ecological resource in the northern Great Lake States, USA, and are threatened by the invasive insect, emerald ash borer (Agrilus planipennis Fairmmaire [EAB]). EAB-induced ash mortality can increase air temperatures, alter understory vegetation communities, and modify wetland hydrology by elevating the water table follow...

Spectral evidence for substrate availability rather than environmental control of methane emissions from a coastal forested wetland

Knowledge of the dynamics of methane (CH4) fluxes across coastal freshwater forested wetlands, such as those found in the southeastern US remains limited. In the current study, we look at the spectral properties of ecosystem net CH4 exchange (NEECH4) time series, and its cospectral behavior with key environmental conditions (temperature (Ts5), water table (WTD) and atmospheric pressure (Pa)) and p...

In Brazil’s Pantanal, a desperate struggle to save a hyacinth macaw refuge from fire

Firefighters are working around the clock to protect a forested ranch in Brazil’s Mato Grosso state that’s an important refuge of the threatened hyacinth macaw. The Pantanal wetlands in which the ranch is located are experiencing severe wildfires, sparked by human activity and exacerbated by drought and climate change....

Forest vegetation change and its impacts on soil water following 47 Years of managed wildfire

<p>Managed wildfire is an increasingly relevant management option to restore variability in vegetation structure within fire-suppressed montane forests in western North America. Managed wildfire often reduces tree cover and density, potentially leading to increases in soil moisture availability, water storage in soils and groundwater, and streamflow. However, the potential hydrologic impacts...

OFO water testing on Limestone Coast

OneFortyOne’s annual water testing program has confirmed its forestry operations are having minimal impact on the Limestone Coast environment. Each winter, OneFortyOne conducts water testing at between 10 and 15 sites to determine whether herbicides applied to control weeds when pine seedlings are planted, are having any off-site effects. Source: Timberbiz OneFortyOne Research Manager Danielle W...

Climate Change and the Future of Southern Wetlands

The Southeast hosts an impressive network of forested wetlands. These wetlands improve water quality, reduce flooding, store excess carbon, and provide important habitat for wildlife. They are also particularly vulnerable to changes in climate and land use. With researchers from North Carolina State University, USDA Forest Service scientist Peter Caldwell designed a model to assess […]...

Estimation of aboveground and belowground carbon stocks in urban freshwater wetlands of Sri Lanka

Abstract Background The occurrence of climate change at an unprecedented scale has resulted in alterations of ecosystems around the world. Numerous studies have reported on the potential to slow down climate change through the sequestration of carbon in soil and trees. Freshwater wetlands hold significant potential for climate change...

Fires in the Pantanal: ‘We are facing a scenario now that is catastrophic’

A canopy of thick smoke blanketed a vast patch of Brazil’s Pantanal wetlands, stretching as far as the eye could see. Underneath, flames were engulfing the yellowed grasslands of the Pantanal Matogrossense National Park, parched by weeks of drought. Fed by gusty winds, the fire had already been burning for days and showed no signs […]...

In Bogotá, communities weave an unlikely wetland success story

BOGOTA — The first time biologist Luis Jorge Vargas visited the Conejera wetlands in 1993 it was as an undergraduate doing research. He said he and his fellow classmates remained “a little bit removed” when they first saw armed guards escorting dump trucks discarding waste into the site. But when he saw the guards beating […]...

Sacramento-San Joaquin System [Chapter 8]

The Great Central Valley of California occupies 22,500 square miles (58,000 square kilometers) in the interior of northern and central California. At the time of the Gold Rush in 1849, nearly 1 million acres (1,600 square miles, 4,000 square kilometers) of riparian vegetation covered the Central Valley floor along with approximately an equal area of wetlands. The riparian area flourished in the la...

It’s not all bad news - riparian areas in the Anthropocene [Chapter 6]

An abundance of information, some of which is included in other chapters in these volumes, documents and laments the historic loss of or changes to riparian ecosystems. Historic impacts to most riparian organisms, ranging in size from cottonwood trees to microbes, are fairly well documented. Causes of these changes are also well documented or speculated upon based on the best available information...
