Use of a Distributed Sensor Network to Parameterize a Model of Flows between the Soil, Vegetation, and Atmosphere in a Mixed Savanna-Agricultural Catchment in South Eastern Burkina Faso.

The hydrologic processes underlying a natural savanna in a semi-arid environment is altered when savanna is converted to agriculture. Inﬁltration is often observed to decrease while rapid runoff increases to the detriment of crop productivity, downstream p ...

Elevation-dependent influence of snow accumulation on forest greening

Ernesto Trujillo Gomez

Rising temperatures and declining water availability have influenced the ecological function of mountain forests over the past half-century. For instance, warming in spring and summer and shifts towards earlier snowmelt are associated with an increase in w ...

The mid-Holocene vegetation of the Mediterranean region and southern Europe, and comparison with the present day

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins

Aim To contribute to the intense debate surrounding the relative influence of climate and humans on Mediterranean-region land cover over the past 6000 years, we assess the Holocene biogeography and vegetation history of southern Europe by means of an exten ...

Biomass selection by floods and related timescales: Part 1. Experimental observations

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier, Peter Molnar, Zhe Jiang

Several research investigations have explored the interaction between morphodynamic and vegetation growth processes from both the modelling and the experimental viewpoints. Results have mainly been concerned with morphologic analyses of the effects of vege ...

Exclusion of root competition increases competitive abilities of subordinate plant species through root-shoot interactions

Alexandre Buttler, Pierre Rémi Mariotte, Charlotte Vandenberghe, Aurélie Thébault

Questions What is the importance of root competition in the competitive abilities of dominant and subordinate species? Location Pair-wise greenhouse experiment based on field data from a semi-natural grassland community in the Swiss Jura Mountains (Col du ...

Biomass selection by floods and related timescales. Part 2: Stochastic modeling

Paolo Perona, Benoît Crouzy

We analyze the results from a flume experiment presented in a companion paper by Perona et al. [1] exploring the selective action of floods on pioneer riparian vegetation. We study the way seedlings react to periodic flow disturbances in the early stages o ...

Evidence and modelling biomass selection by floods in a riverbed

Paolo Perona, Benoît Crouzy

Riparian and in-bed vegetation growth and erosion dynamics are strongly coupled with river hydrologic and morphodynamic processes. Many field observations documented the engineering role of vegetation and its contribution to build, stabilize and control er ...

Hydrological drivers of wetland vegetation community distribution within Everglades National Park, Florida

Andrea Rinaldo

The influence of hydrological dynamics on vegetation distribution and the structuring of wetland environments is of growing interest as wetlands are modified by human action and the increasing threat from climate change. Hydrological properties have long b ...

Effect of dung deposition on small-scale patch structure and seasonal vegetation dynamics in mountain pastures

Alexandre Buttler, Charlotte Vandenberghe, François Gillet

Cattle activity greatly influences plant species composition and biomass production of grassland ecosystems. Dung deposition by cattle together with grazing and trampling can be considered as one of the important factors driving vegetation dynamics in past ...

A rapid response of testate amoebae and vegetation to inundation of a kettle hole mire

Mariusz Lamentowicz

Our palaeoecological study covers 73 years of history (1929-2002) of a kettle hole peatland inundated by water from a nearby, dammed lake. Testate amoebae, pollen and non-pollen palynomorphs (NPPs) were used to track the shift to wetter conditions in the p ...
