INTRODUCTION

BioHydrology 2016 is the fourth international conference on biohydrology, after those of Prague (2006), Bratislava (2009) and Landau (2013). As the previous conferences, the aim is providing a forum to discuss any question related to the interactions between biotic systems and hydrology. Such interactions can be simple, bidirectional or including feedback, and occurring at any spatial or time scale. The conference is addressed to experts from ecology, hydrology, geography, soil science, environmental sciences, biology, geomorphology, forestry and similar; but any expert focusing in this issue is welcome and interdisciplinary contributions are encouraged.

The conference includes five topics covering a wide thematic range. This time the congress moves from central Europe to Almeria, at the extreme south-east Spain, probably the most arid region in Europe, and the peculiarities of the interactions between living organisms, biocenosis or organic matter and hydrological processes in drylands is the first topic. The areas were water is a limiting factor during at least a part of the year account for more than the 40% of the emerged land at planetary scale. The increasing human population as well as its socio-economic development increases the water demand and the availability of water is already a concern in most countries. On the other hand, this concern tends to increase due to climatic change. The deep understanding of these natural biohydrological processes, even those studied at very detailed scales, can have important consequences, e.g., in food production, water harvesting, nature conservation, flood prevention, ecosystem function understanding, land management or guidelines for sustainable land uses.

The conference includes some plenary lectures from top international scientists, and a session for every topic, with keynote lectures from relevant scientists in every session as well as oral and poster communications from the participants.

Topics

1. Water-limited conditions and biohydrology

Conveners: Yolanda Cantón, Esteban Jobbagy, Giora J. Kidron, Francisco Domingo, Emilio Rodríguez Caballero.

Keynote speakers: Bradford Wilcox, Xiao Yan Li, Cristina Armas, Susana Bautista

This session will explore the peculiarities of the relationships between hydrology and living organisms in drylands at multiple spatial and temporal scales. The effects of the distinctive aspects of dry ecosystems, such as their discontinuous vegetation cover or the presence of biological soil crusts, on the soil-water balance are addressed, including two-way water fluxes along the soil-vegetation-atmosphere continuum. Contributions also deal with the effects of the amount and type of water inputs (rain events of varying size and intensity, run-off/run-on fluxes, or dew) on the ecophysiological functioning of dryland plants, biocrusts and soil microbiota, and the structure of the communities that they integrate. Investigations of the dynamic feedbacks that emerge from the reciprocal interactions between the living organisms or biocenosis and the hydrological system are especially invited to participate in this session.

2. Biohydrology in land degradation and restoration

Conveners: Albert Solé-Benet, Elisabeth Huber-Sannwald, Mariano Moreno de las Heras, Alexia Stokes

Keynote speakers: Rony Wallach, Juan Puigdefábregas, Jan Frouz, Stanley J.Kostka

Land degradation in drylands involves large changes in key biohydrological processes that rule ecosystem stability (e.g., surface redistribution of water, nutrients and seeds, landscape optimization of the use and cycling of resources). This degradation frequently leads to persistent degradation, which hinders the recovery of landscape function and integrity. This session will be devoted to the study of interrelationships between hydrology and living organisms from the perspective of their impacts on land degradation and restoration. The session will include contributions on the effects of biohydrological feedbacks in land degradation, as well as on the development of soil and plant management strategies to optimize ecological restoration for sustainable land use.

3. Hydrological effects of plant-soil complex from patch to landscape

Conveners: Lubomir Lichner, Erik L.H. Cammeraat, Andrea Carminati, Artemi Cerdá

Keynote speakers: Mathieu Javaux, Saskia Keesstra, Radka Kodešová, Peter Mathews.

This session will discuss the role of plants and soils in biohydrological interactions. Topics include bacterial and root exudates altering the wetting properties of soil particles, rhizosphere biophysical properties, root water uptake dynamics and root-soil interactions. Contributions addressing strategies to reduce water repellency in forest, agriculture and turf science are encouraged. Multiscale and cross-scale studies of biohydrological processes at different time scales in varying ecosystems are welcome.

4. The impact of forest fires on hydrology

Conveners: Jorge Mataix-Solera, Matthias Boer, Saskia Keesstra, Paulo Pereira

Keynote speakers: Patrick Lane, Pete Robichaud

This session will address the effects of fires on soil properties and their consequences for hydrology. This includes all kinds of fires, not only those affecting forests but also those affecting shrublands, grasslands, croplands, or meadows or any kind of discontinuous dryland natural vegetation, as well as prescribed fires.

5. Role of biogeochemical interfaces in biohydrology

Conveners: Gabriele E. Schaumann, Jörg Bachmann

Keynote speakers: Horst H. Gerke, Marcus A. Horn, Nick Jarvis

The role of biological activity in regulating the physical and hydraulic properties of the porous medium, its impact on micro- as well as on macroscale fluxes and its potential in modifying numerous material functions remains largely ignored, especially by soil hydrologists. Vice versa, biologists often use oversimplified models and experimental designs that ignore governing properties of natural environments affecting biological activity in unsaturated soils. This session aims to describe the complex interplay of interactions between biological systems and interfaces in the soil from the pore to the landscape scale.
