The last interglaciation (~130 to 116 ka) is a time period with a strong astronomically induced seasonal forcing of insolation compared to the present. Proxy records indicate a significantly different climate to that of the modern, in particular Arctic summer warming and higher eustatic sea level. Because the forcings are relatively well constrained, it provides an opportunity to test numerical models which are used for future climate prediction. In this paper we compile a set of climate model simulations of the early last interglaciation (130 to 125 ka), encompassing a range of model complexities. We compare the simulations to each other and to a recently published compilation of last interglacial temperature...

Alnus viridis seedlings were planted on placer mine spoil in an Alaskan subalpine watershed to bypass a seedling establishment bottleneck for A. viridis, and to evaluate the interaction between A. viridis and the dominant riparian woody plants, Salix alaxensis and Populus balsamifera. The study area was divided into 11 replicate blocks, each on a homogeneous recontoured spoil pile. Blocks were divided into two 0.01 ha plots, and treatments without (control) and with 84 planted A. viridis seedlings were randomly assigned to plots. After 10 years, the Alnus treatment had a dense stand of A. viridis 1-2 m tall, while the control had fewer, smaller seedlings. Compared to the control, planted A. viridis had a neutral...
