Download or read book The Evolutionary Synthesis written by Ernst Mayr and published by Harvard University Press. This book was released on 1998 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology was forged into a single, coherent science only within living memory. In this volume the thinkers responsible for the "modern synthesis" of evolutionary biology and genetics come together to analyze that remarkable event. In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines varied considerably in their degree of acceptance of Darwin's theories. Mayr shows us that these differences were played out in four separate periods: 1859 to 1899, 1900 to 1915, 1916 to 1936, and 1937 to 1947. He thus enables us to understand fully why the synthesis was necessary and why Darwin's original theory--that evolutionary change is due to the combination of variation and selection--is as solid at the end of the twentieth century as it was in 1859.

This book was released on 2013-03-20 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant geographical description of the area, syntaxonomy, spatial patterns, floristic richness, structure of plant communities in relation to soil properties and herbivore influence were described for a mountain region that is difficult to access. Seasonal, inter-annual, and long-term dynamics of vegetation are discussed on the base of long-term observations as well as pollen and phytolith analyses. Population biology of alpine plants is studied by combination of field observations and mathematical modelling. Plant population strategies and soil seed banks are described for alpine plants from several communities. Results of long-term ecological experiments (plant reciprocal transplantations, dominant removals, light limitation) showed the significance of competition and facilitation for community organization. Structure of soil algal and fungal communities is represented as well as mycorrhiza of alpine plants. Main animal groups (wild) history and modern nature conservation problems are discussed.
