This ebook offers a transparent and available advent to the modeling of organic invasions. It demonstrates the most recent theories and versions, and comprises information and examples from numerous case experiences exhibiting how those types should be utilized to difficulties from lethal human illnesses to the unfold of weeds.

Their concern is accentuated by the common conception of obesity as a causal precursor of diabetes and cardiovascular disease. In the context of this major epidemic there has been no commensurate surge in research into the etiology/etiogenesis of obesity – barogenesis could be the term for weight gain (Gr. baros, ‘weight’) – as the causation of weight gain has been taken to be obvious and well known, on a-priori grounds. Gary Taubes (ref. in sect. 1) addresses this situation quite critically. ) – and conversely, of course.

In the Conclusion, very notably, there was nothing about dietary carbohydrates in the etiogenesis of obesity and of its associated metabolic anomalies in the metabolic syndrome. Instead, the review was said to have been about “childhood overweight and its metabolic consequences” (italics ours). And as for the etiogenesis of overweight/obesity, the conclusion was a simple affirmation of the prevailing orthodoxy (sect. 4): “Strategies aimed at reducing caloric intake and increasing caloric expenditure through regular exercise, early and aggressively, are necessary :::” The 2011 issue of the Reviews, on screening – a topic in respect to prostate cancer already (above) – began with an Overview by R.
