Total mercury and methylmercury dynamics in upland���peatland watersheds during snowmelt

Wetlands, and peatlands in particular, are important sources of methylmercury (MeHg) to susceptible downstream ecosystems and organisms, but very little work has addressed MeHg production and export from peatland-dominated watersheds during the spring snowmelt. Through intensive sampling, hydrograph separation, and mass balance, this study investigated the total mercury (THg) and MeHg fluxes from ...

Natural landscapes key to Canadian cities, rural areas for building climate resilience, experts say

In the South Okanagan area of B.C. lies an important area of grassland and wetlands known as the Park Rill Floodplain. It's home to species at risk like the peregrine falcon and the western screech owl. And as of last week, the 61 hectares of land are now protected from development after being purchased by the Nature Trust of B.C....

Demography of the Oregon spotted frog along a hydrologically modified river

Altered flow regimes can contribute to dissociation between life history strategies and environmental conditions, leading to reduced persistence reported for many wildlife populations inhabiting regulated rivers. The Oregon spotted frog (Rana pretiosa) is a threatened species occurring in floodplains, ponds, and wetlands in the Pacific Northwest with a core range in Oregon, USA. All life stages of...

Environmental defenders in Ecuador aren’t safe, new report shows

QUITO — For almost five years, Andres Durazno and his niece Elizabeth would march, block roads, and confront mining authorities and police together. They were leading the fight against mining in their community of Rio Blanco in the south of Ecuador, and defending the wetlands that the mine was destroying in the surrounding Andean mountains, […]...

Hydrologic variability in black ash wetlands: Implications for vulnerability to emerald ash borer

Black ash (Fraxinus nigra) wetlands are widespread, forested landscape features in the western Great Lakes region. However, the future of these ecosystems is threatened due to impending spread of the invasive emerald ash borer (EAB), which results in tree mortality, decreased transpiration, and potential shifts to wetter, non-forested conditions. The vulnerability to such ecohydrologic shifts like...

Evaluating the Untapped Potential of U.S. Conservation Investments to Improve Soil and Environmental Health

There is increasing enthusiasm around the concept of soil health, and as a result, new public and private initiatives are being developed to increase soil health-related practices on working lands in the United States. In addition, billions of U.S. public dollars are dedicated annually toward soil conservation programs, and yet, it is not well quantified how investment in conservation programs imp...

Time lags: Insights from the U S long term ecological research network

Ecosystems across the United States are changing in complex ways that are difficult to predict. Coordinated long-term research and analysis are required to assess how these changes will affect a diverse array of ecosystem services. This paper is part of a series that is a product of a synthesis effort of the U.S. National Science Foundation���s Long Term Ecological Research (LTER) network. T...
