Ecosystem size and resource flows are key factors driving biodiversity and ecosystem function. However, the question of whether and how these drivers interact has been largely overlooked. Here, we show how ecosystem size asymmetry affects biodiversity and function of two‐patch meta‐ecosystems connected through flows of nonliving resources using a ...

DNA polymerase activity from Tetrahymena pyriformis
The DNA polymerase of Z’etrahymena pyrifomis was first isolated from crude extracts of the cells by Pearlman and Westergaard [ 1,2] . The specific activity of this polymerase was increased if, prior to extraction, the cells were treated with either ultraviolet irradiation, electron irradiation, methotrexate plus uridine or ethidium bromide [2&4]. Using
