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.

Assessing Cultural And Ecological Variation In Ethnobiological Research: The Importance Of Gender, Jeanine M. Pfeiffer
Jeanine M. Pfeiffer
Contending that a significant portion of current ethnobiological research continues to overlook cultural variation in traditional ecological knowledge (TEK) and practice, this paper explores the potential impacts of gender-imbalanced research on data collection, hypothesis testing, and the formulation and application of ethnobiological inventories and theories. A multidisciplinary review of over 220 studies addresses commonly held stereotypes underlying gender-imbalanced field research and demonstrates the need for more inclusive, finely-tuned studies which disaggregate indigenous knowledge and practice by gender. The paper outlines factors underlying gender-based spatial and temporal variation in ecosystem exposure and traditional ecological knowledge in rural societies worldwide, and discusses …
