St Lawrence River

Benthos samples collected in 37 sites interspersed along a 230 km stretch of the St. Lawrence River, between Lake St. Pierre and Ile aux Oies, were analyzed. The distribution of the main taxa shows the downstream succession of many of the dominant species. Benthic groups of the upstream and downstream sections of the upper estuary are characterized by the hydrobiid B. tentaculata and the viviparid V. georgianus, respectively. The structure of the benthic groups undergoes a gradual change downstream from Gentilly and the samples collected in the lower section add up to a much more heterogeneous community than the samples collected in the upper or the middle reaches of the estuary.[Journal Translation]

St Lawrence River

The structure and distribution of the macrobenthos were determined to evaluate the present state of the section of the St. Lawrence River which might be affected by the cooling waters of the Gentilly nuclear reactors. Ten groups were recognized, characterized by the presence of one to three constant and dominant species. In lentic conditions characterized by the presence of the gastropod Bithynia tentaculata the zonation is depth dependent. Three groups inhabit the littoral zone characterized by the Glossoscolecidae Sparganophilus tamesis. There are two groups in the sublittoral zone characterized by the Tubificidae Limnodrilus hoffmeisteri and two groups in the deep waters characterized by the Sphaeriidae Sphaerium striatinum. Bithynia tentaculata, a hydrobiid, seldom inhibits the lotic environment where the Tubificidae Limnodrilus hoffmeisteri is the only typical species.

Seventeen samples were collected at regular intervals from September 1970 to December 1971 from four sites on lake St. Louis; these stations received their water either from the St. Lawrence River, the Ottawa River, or both. For each species and sample of the 178 phytoplankton entities found, the number of cells per liter was estimated. A general view of the distribution of plankton organisms at each station is given as well as the seasonal variation of the major systematic groups and the dominant species.

The studies were mostly concentrated in Nine forest ranges of the WLS including the core areas. The soil of this region mostly is dry, red and with iron and silica content. Though the soil mites are prevalent in moist humid condition, we got a diversed population of 20 different species under 14 genera which is less than average probably due to the soil condition. Protoribates magnus is the dominant species in this study. The species with larger ranges were Scheloribates curvialatus.

Human beings have evolved to become the most dominant species on Earth. This astonishing transformation is usually explained in terms of cognitive ability—people are just smarter than all the rest. But this book argues that culture—our ability to learn from each other—has been the essential ingredient of our remarkable success. The book shows how a unique combination of cultural adaptation and large-scale cooperation has transformed our species and assured our survival—making us the different kind of animal we are today. The book is based on the Tanner Lectures delivered at Princeton University, featuring challenging responses across the chapters.
