Systematic Analysis of Periodic Vegetation Patterns [PDF]
Progress of Theoretical Physics, 2001 Summary: Spatially periodic vegetation patterns are observed in many semiarid regions. They are classified according to their symmetry as vegetation stripes on hillsides or spotted patterns on flat ground. We propose a simple model based on the interactions among water, soil and vegetation, which gives a systematic description of the variety of ...

Similarity of vegetation dynamics during interglacial periods [PDF]
Proceedings of the National Academy of Sciences, 2005 The Velay sequence (France) provides a unique, continuous, palynological record spanning the last four climatic cycles. A pollen-based reconstruction of temperature and precipitation displays marked climatic cycles. An analysis of the climate and vegetation changes during the interglacial periods reveals comparable features and identical major ...

Periodic versus scale-free patterns in dryland vegetation [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2010 Two major forms of vegetation patterns have been observed in drylands: nearly periodic patterns with characteristic length scales, and amorphous, scale-free patterns with wide patch-size distributions. The emergence of scale-free patterns has been attributed to global competition over a limiting resource, but the physical and ecological origin of this ...

Atmosphere, 2022 Climate change brings to the whole world numerous challenges such as an increase in the global temperature, weather fluctuations, periods of drought and heat alternating the local floods. While the majority of the effects are negative for agricultural production, some can be beneficial. Our work presents the evaluation of the changes in the duration of

Return period of vegetation uprooting by flow [PDF]
Journal of Hydrology, 2019 Abstract Fluvial environments are dynamic systems whose evolution and management are strongly affected by the resilience of riparian vegetation to uprooting by flow. Similarly to other natural phenomena, the interactions between flow, sediment and vegetation uprooting is governed by both the magnitude and duration of hydrological events. In this work,

Vegetation context and climatic limits of the Early Pleistocene hominin dispersal in Europe [PDF]
, 2010 The vegetation and the climatic context in which the first hominins entered and dispersed in Europe during the Early Pleistocene are reconstructed, using literature review and a new climatic simulation. Both in situ fauna and in situ pollen at the twelve
