Macroinvertebrate Fauna

The development of the zoobenthic biocoenosis in the River Rhine in Germany during the 20th century has been documented in literature and by own investigations. The diversity of species and the structure of zoocoenosis are the elements of comparison. They show a drastic and continuing impoverishment in the benthic macroinvertebrate fauna throughout the 1950s, 1960s, and in the early 1970s. Since the raid-seventies a steady recovery of the communities has been observed. Causal dependencies between the development of the zoocoenosis and environmental factors like water pollution, river training, navigation and invasion of alien species (Neozoa) are discussed. Actions for improving the ecological situation are proposed.

Species Responses

Species responses to grazing and environmental factors were studied in an arid halophytic shrubland community in Western Australia. The grazing responses of major shrub species were defined by using reciprocal averaging ordination of botanical data, interpreted in conjunction with a similar ordination of soil chemical properties and measures of soil erosion derived from large-scale aerial photographs. An apparent small-scale interaction between grazing and soil salinity was also defined. Long-term grazing pressure is apparently reduced on localised areas of high salinity. Environmental factors affecting species distribution are complex and appear to include soil salinity, soil cationic balance, geomorphological variation and the influence of cryptogamic crusts on seedling establishment.
