From the reviews: "Springer's Ecological Studies series provides an invaluable database and synthesis in ecology that students and researchers alike should be aware of. The series provides very useful insights into ecosystems, providing background and up-to-date information on whole ecosystems and how they function in relation to their environment. This book is no exception. ... I would recommend...
Recent projections of climatic change have focused a great deal of scientific and public attention on patterns of carbon (C) cycling as well as its controls, particularly the factors that determine whether an ecosystem is a net source or sink of atmospheric carbon dioxide (CO2). Net ecosystem production (NEP), a central concept in C-cycling research, has been used by scientists to represent two different...
ABSTRACT Understanding terrestrial carbon metabolism is critical because terrestrial ecosystems play a major role in the global carbon cycle. Furthermore, humans have severely disrupted the carbon cycle in ways that will alter the climate system and directly affect terrestrial metabolism. Changes in terrestrial metabolism may well be as important an indicator of global change as the changing temperature...
Abstract Downward transport of water in roots, in the following termed inverse hydraulic lift, has previously been shown with heat flux techniques. But water flow into deeper soil layers was demonstrated in this study for the first time when investigating several perennial grass species of the Kalahari Desert under field conditions. Deuterium labelling was used to show that water acquired by roots...
Abstract The need to combine data from CO2 field experiments with climate data remains urgent, particularly because each CO2 experiment cannot run for decades to centuries. Furthermore, predictions for a given biome need to take into account differences in productivity and leaf area index (LAI) independent of CO2-derived changes. In this study, we use long-term weather records and field data from...
On the basis of terpene composition, populations ofB. microphylla show north to south affinities on both the Baja California peninsula and the northwest coast of Mexico. The lack of east to west population affinities corresponds with the presumed absence of land connections between the peninsula and mainland throughout the history of this taxon. Morphological similarities between populations in an...
