This systematic treatment of the diatoms of the U.S. is written for the use of all those concerned with the multitude of kinds and the fascinating diversity of this very large and important group of algae of our fresh waters.

This volume represents the first part of a two part systematic treatment of the freshwater diatom flora of continental U.S. exclusive of Alaska.

Besides those taxa found in fresh water, a few taxa found in estuaries of rivers and belonging to genera that commonly occur in fresh water are included. No strictly fossil species are included; however, many of the species embraced are found in recent fossil material.

Although this book is concerned with the U.S., it should be helpful to the students of diatom floras in Mexico, Canada, and other areas. Illustrations.

Taxing Caloric Sweetened Beverages: Potential Effects on Beverage Consumption, Calorie Intake, and Obesity (ISBN: 9781437935931)

Despite budget deficits and calls by health advocates, soda taxes have failed to pass recently in New York, Philadelphia, Vermont, Mississippi, Kansas and Alaska, the New York Times reports.

The link between high U.S. obesity rates and the over-consumption of added sugars, largely from sodas and fruit drinks, has prompted calls for a tax on caloric sweetened beverages (CSB). Faced with a tax, consumers may reduce consumption of these CSB and substitute non-taxed beverages, such as bottled water, juice, and milk.

A tax-induced 20% price increase on CSB could cause an average reduction of 3.8 pounds of body weight over a year, for adults and an average of 4.5 pounds over a year, for children.

Given these reductions in calorie consumption, results show an estimated decline in adult overweight prevalence and obesity prevalence, as well as the child at-risk-for-overweight prevalence and the overweight prevalence. Charts and tables.
