These Acacia species, having evolved in a Mediterranean fire-prone environment, thrived at the Cape in the absence of their natural controls and have since become problematic invasive species posing considerable threats to local biodiversity van Wilgen Holling, C.

Brook trout Salvelinus fontinalis , brown bullhead Ameiurus nebulosus , pumpkinseed Lepomis gibbosus , or smallmouth bass Micropterus dolomieu were other target species. MacArthur, Robert H. The simple, brilliant statements of molecular biology capture the imagination and offer a unified theoretical framework for a wide range of biological principles as they apply to certain levels of biological organization. Concerning most of the mercury now sequestered in the sediments of aquatic systems—mainly in marine sediments, Camargo concluded, however, that the high mercury concentrations currently reported in the global environment are a consequence of the huge pollution caused by human activities during the twentieth century.
