The species–area relationship (SAR) plays a central role in biodiversity research, and recent work has increased awareness of its temporal analogue, the species– time relationship (STR). Here we provide evidence for a general species–time–area relationship (STAR), in which species number is a function of the area and time span of sampling, as well as their interaction. For eight assemblages, ranging from lake zooplankton to desert rodents, this model outperformed a sampling-based model and two simpler models in which area and time had independent effects. In every case, the interaction term was negative, meaning that rates of species accumulation in space …

Straw bale building offers high performance at a low cost. Bale building, developed on the grasslands of Nebraska at turn of the last century, has been rediscovered. High insulation values and high interior thermal mass make straw bales a good choice for passive solar design.
