On the biomechanics of seedling anchorage

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier

We propose a minimal model for the response of vegetation to pullout constraints at early development stage. We try to capture both the average mechanical properties of the root system and the stochastic component of the uprooting process of seedlings. We ...

Influence of root characteristics and soil variables on the uprooting mechanics of Avena sativa and Medicago sativa seedlings

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier, Paolo Burlando

The success of seedlings and rejuvenated woody debris growing on river bedforms depends on the resistance to uprooting by flow provided by their simple root architecture. Avena sativa and Medicago sativa seedlings were used in flume experiments as prototyp ...

Characterization of fulvic acid fractions of dissolved organic matter during ice-out in a hyper-eutrophic, coastal pond in Antarctica

Jennifer Guerard

Dissolved humic material (HDOM) is ubiquitous to all natural waters and its source material influences its chemical structure, reactivity, and bioavailability. While terrestrially derived HDOM reference materials distributed by the International Humic Subs ...

Land use and soil texture effects on organic carbon change in dryland soils, Senegal

Claire Guenat, Assize Touré

Soil organic carbon (SOC) losses due to poor soil management in dryland are now well documented. However, the in- fluence of soil properties on organic carbon change is not well known. The groundnut plant (Arachis hypogaea L.), and the dominant crop system ...

Effects of Subordinate Plant Species in Plant and Soil Community Structure and Ecosystem Functioning

Pierre Rémi Mariotte

The relevance of biodiversity to human health is an increasing international political issue as it causes concern for ethical and aesthetic reasons, but also has a strong impact on ecosystem properties and ecological goods and services utilised by humanity ...

Assessing the Bacterial Ecology of Organohalide Respiration for the Design of Bioremediation Strategies

Noam Shani

Groundwater is essential for human activities and is sometimes referred to as a non-renewable resource in the same way as oil and gas. During the past century, precious groundwater reserves worldwide have been threatened by anthropogenic release of chemica ...

Sustainable soil and water resources: modelling soil erosion and its impact on the environment

David Andrew Barry

With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of land to intensive agriculture has led to dramatic decreases ...

Soil-vegetation patterns in secondary slash and burn successions in Central Menabe, Madagascar

Alexandre Buttler, Jean-Michel Gobat

Slash and burn agriculture is a traditional and predominant land use practice in Madagascar and its relevance in the context of forest preservation is significant. At the end of a cycle of culture, the fields become mostly weed covered and the soil fertili ...

Extreme Deuterium Excesses in Ultracarbonaceous Micrometeorites from Central Antarctic Snow

Anders Meibom, François Robert

Primitive interplanetary dust is expected to contain the earliest solar system components, including minerals and organic matter. We have recovered, from central Antarctic snow, ultracarbonaceous micrometeorites whose organic matter contains extreme deuter ...

Response of terrestrial N2O and NOx emissions to abrupt climate change

Jed Oliver Kaplan, Mirjam Pfeiffer

Being a potent greenhouse gas, N2O emitted by the terrestrial biosphere during abrupt climate change events could have amplified externally forced warming. To investigate this possibility, we tested the sensitivity of terrestrial N2O emissions to an abrupt ...
