This week, we need to do work to address a component of our application that requires immediate attention. As a result, you may experience ERA to be intermittently available. We apologize for any inconvenience this may cause, and thank you for your patience as we attend to the care and feeding of ERA!

Ecological controls on net ecosystem productivity of a mesic arctic tundra under current and future climatesDownload
Abstract: Changes in arctic C stocks with climate are thought to be caused by rising net primary productivity (NPP) during longer and warmer growing seasons, offset by rising heterotrophic respiration (Rh) in warmer and deeper soil active layers. In this study, we used the process model ecosys to...
Effects of the endophyte Piriformospora indica on growth, physiology and water relations of tobacco (Nicotiana tobacum)Download
In the current study, wildtype and transgenic tobacco constitutively over-expressing Arabidopsis aquaporins PIP 1;4 and PIP 2;5 were grown in association with the endophyte Piriformospora indica. Root hydraulic conductivity along with various physiological parameters and aquaporin expression were...
Physiological responses of glycophytic and halophytic grasses Poa pratensis, Poa juncifolia, and Puccinellia nuttalliana to salt stressDownload
Responses of two halophytic grasses Puccinellia nuttalliana and Poa juncifolia to treatments with NaCl were compared with the glycophytic grass Poa pratensis to better understand salt tolerance mechanisms in these plants. The experiments were carried out under controlled-environment conditions...
Resource allocation, water relations and crown architecture examined at the tree and stand-level in northern conifersDownload
Variation in quantity of light has driven plants to employ many strategies in order to persist in high and low light. It is also a primary driver of lower branch mortality and crown recession. Fine roots and leaves are complimentary tissues representing belowground and aboveground resource...
