LAWSC provides easy flood tracking on the web – 25 May 2007

Flooding is a concern for everyone in Louisiana. Floods demand immediate and decisive action by governmental entities, businesses, and individual citizens, all of whom have to make critical decisions that directly impact the extent, duration, and mitigation of losses resulting from flooding. How high will the water get? How long will the flood last? What areas will be affected? What roads will...

Divergent species‐specific impacts of whole ecosystem warming and elevated CO2 on vegetation water relations in an ombrotrophic peatland

Boreal peatland forests have relatively low species diversity and thus impacts of climate change on one or more dominant species could shift ecosystem function. Despite abundant soil water availability, shallowly rooted vascular plants within peatlands may not be able to meet foliar demand for water under drought or heat events that increase vapor...
