Convergent evolution in warm deserts(1st Edition) An examination of strategies and patterns in deserts of Argentina and the United States (US/IBP synthesis series 3) by Gordon H. Orians, OttoThomasSolbrig, Otto T. Solbrig Hardcover, 333 Pages, Published 1977 by Dowden, Hutchinson & Ross, Inc. ISBN-13: 978-0-87933-276-1, ISBN: 0-87933-276-X
"the demography of branches on trees and of the relationships between numbers
and size as the 'architectural blueprint' of the tree manifests itself. A
rapprochement between tree modellers and tree biologists remains to be made,
but the new insights on plant morphology offered by Halle, Oldeman & Tomlinson
(1978) must be a foundation. The task of counting and measuring branches on
trees is tedious, but it seems that it can be achiev ..."
The World's Savannas(1st Edition) Economic Driving Forces, Ecological Constraints and Policy Options for Sustainable Land Use (International Congress, Symposium and Seminar Series,) by OttoThomasSolbrig, John Young M. D., Editor-M.D. Young, Michael Denis Young Hardcover, 350 Pages, Published 1993 by Crc Press ISBN-13: 978-1-85070-417-1, ISBN: 1-85070-417-1
"In this book, natural and social scientists examine savanna land use within a policy perspective. The text assesses the ecological, social, and economic constraints to savanna development and identifies the nature of policy changes necessary to enhance prospects for economic growth and development throughout the savanna regions. The book emphasizes development of policy recommendations at a national and international level."
""So Shall You Reap" is a broad-gauged exploration of the intersections of farming and history. Beginning with the prehistorical era, Otto and Dorothy Solbrig describe the evolution of farming. When and how did people learn to irrigate, to fertilize, to rotate their crops -- and why?Along with its fundamental importance to history, farming has radically altered the physical world. Natural landscapes have been completely transformed to pr ..."

" As the world transitions from an industrial society to an information society, agriculture has undergone a dramatic transformation. Food production in the 20th century was transformed by three revolutions: first mechanical, then genetic, and finally chemical. Now, in the 21st century, agriculture is going through at least two more revolutions: an information technology revolution leading to precision farming, and a biotechnology revol ..."
"The loss of biodiversity of organisms and the effects of global change (including changes in soil, water, vegetation and atmosphere) are two major issues that confront today’s biologists and environmental scientists. The objective of this book is to assess biodiversity loss in the context of global change. The book was originally published in 1992 by the International Union of Biological Sciences, and is now reprinted with minor revisio ..."
"Savannas are the most widespread ecosystem in the tropics and as such are subjected to great human pressure that may result in massive soil degradation. The book addresses the role of species in the function of savanna ecosystems. It is shown that savannas are enormously diverse and that four factors determine the function of savanna ecosystems: Plant Available Moisture; Plant Available Nutrients; Fire; Herbi ..."
"2 Determinants of Tropical Savannas Otto T. Solbrig, Ernesto Medina, and Juan F
. Silva 2.1 Introduction Tropical savannas, defined as ecosystems formed by a
continuous layer of graminoids (grasses and sedges) with a discontinuous layer
of trees and/or shrubs, are the most common vegetation type (physiognomy) in
the tropics. Tropical savannas are found over a wide range of conditions: rainfall
from approximately 200 mm to 1500 mm a ..."
