    Plant ecology
    • This textbook covers Plant Ecology from the molecular to the global level. It covers the following areas in unprecedented breadth and depth: - Molecular ecophysiology (stress physiology: light, temperature, oxygen deficiency, drought, salt, heavy metals, xenobiotica and biotic stress factors) - Autecology (whole plant ecology: thermal balance, water, nutrient, carbon relations) - Ecosystem ecology (plants as part of ecosystems, element cycles, biodiversity) - Synecology (development of vegetation in time and space, interactions between vegetation and the abiotic and biotic environment) - Global aspects of plant ecology (global change, global biogeochemical cycles, land use, international conventions, socio-economic interactions) The book is carefully structured and well written: complex issues are elegantly presented and easily understandable. It contains more than 500 photographs and drawings, mostly in colour, illustrating the fascinating subject. The book is primarily aimed at graduate students of biology but will also be of interest to post-graduate students and researchers in botany, geosciences and landscape ecology. Further, it provides a sound basis for those dealing with agriculture, forestry, land use, and landscape management.

    • The identification of inputs and outputs is crucial in testing and analyzing complex systems. By adhering to natural laws like conservation of mass and electroneutrality, input/output analysis reveals the system's dynamic status, indicating whether changes are reversible or irreversible and if input variations cause hysteresis responses. Additionally, measuring input and output fluxes can reveal a system's storage capacity, resilience to external variations, and potential structural changes, aiding predictions about ecosystem stability. This analysis is akin to engineers measuring the input/output properties of electronic devices, where the overall instrument's performance is compared to expected design variations. Varying inputs and outputs provide insights into the stability and regulatory properties of the device. However, the circuit as a whole exhibits unique properties that cannot be inferred by examining individual components in isolation. The instrument's overall input/output characteristics differ from those of its subcircuits, highlighting the importance of a holistic approach in analysis.
