In hydroponics, the addition of EDTA caused a decrease in Cd uptake by maize, particularly when the ratio of total EDTA ([EDTA] (T) ) to total Cd ([Cd] (T) ) was greater than 1. At [Cd] (T) = 1 mu M, when [EDTA] (T) /[Cd] (T) < 1, the model indicated that Cd uptake was predominantly due to the absorption of free Cd2+, whose pool was replenished by the dissociation of Cd-EDTA. When [EDTA] (T) /[Cd] (T) > 1, the low Cd uptake was mostly due to Cd-EDTA absorption. In soil spiked with 5 mg Cd kg(-1), Cd uptake was not affected by the various EDTA additions, because of the buffering capacity of the soil solid phase.

Kinetic results showed that biochar particle sizes controlled metal sorption rate despite a similar specific surface area, which indicated a limitation by intra-particle diffusion. Isotherms showed a partially reversible sorption to biochar following the order Pb>Cu>CdZn>Ni, which we explained primarily by the (co)precipitation of metals or their adsorption on specific biochar mineral phases. Effective metal immobilization was observed with biochar in both contaminated soils but could not be predicted from the sorption isotherms. This immobilization appeared to be governed by the soil pH increase, which induced a greater retention of metals on soil particles.

Based on a solid-liquid extraction using a Tenax (R) resin, we suggest a protocol to assess the bioavailability of PAHs, dedicated to aged industrial wasteland soils. Desorption kinetics were measured on three representative contaminated industrial soils. Results were modeled using a first order two-compartment model that provided an estimate of the rapidly desorbing fraction, which was considered to be available, over a 30 h extraction period.

Ni was probably adsorbed onto amorphous Fe-oxides and was also exchangeable in secondary smectites. High availability of Ni in soils was confirmed by DTPA extractions. However, it varied significantly along the toposequence, being higher in upslope soils, where Ni-bearing amorphous Fe-oxides were abundant and total organic carbon higher and sensibly lower downslope on the Vertisols: Ni-DTPA varied from 285 mg kg(-1) in the surface of soil I (upslope) to 95.9 mg kg(-1) in the surface of Fluvic Cambisols.

However, alternative cropping patterns which include rhizosphere microbial communities can significantly influence the extraction of metals, as well as soil protection and quality. Therefore, the objective of this work was to study the effect of species-rich vegetation cover, which consisted of three hyperaccumulator plant species, on the efficiency of nickel extraction from a naturally mineralized ultramafic soil. An experiment was set up with three hyperaccumulator species (Leptoplax emarginata, Noccaea tymphaea and Alyssum murale). Plants were cultivated separately (monospecific cover), or in combination (multispecies cover) in mesocosms under controlled conditions, on a nickel-rich ultramafic soil. Plants were grown for 92 days in controlled conditions. Each plant produced more biomass when grown in multispecies cover than alone. Noccaea and Alyssum showed the highest shoot Ni concentrations but Alyssum had by far the lowest shoot biomass. So, in this soil, Noccaea and Leptoplax have greater potential for hyperaccumulation than Alyssum. The amount of nickel accumulated in total biomass of Noccaea alone and of the multispecies cover was higher than that accumulated in either the monospecies Leptoplaxor Alyssum. Furthermore, the highest values of microbial biomass were obtained with the multispecies cover and a consistent production of auxin compounds by bacterial communities was measured, which emphasized the role of rhizosphere bacteria. The bacterial genetic structure also depended on the plant covers. A combination of the three species (multispecies cover), could be a good strategy for phytoremediation. (C) 2014 Elsevier B.V.

Some forest understorey plants recover carbon (C) not only from their own photosynthesis, but also from mycorrhizal fungi colonizing their roots. How these mixotrophic plants use the resources obtained from mycorrhizal and photosynthetic sources remains unknown. 2. We investigated C sources and allocation in mixotrophic perennial orchids from the genus Epipactis. Based on the assumption that fungal biomass has high delta C-13 and N content, while photosynthetic biomass has lower delta C-13 and N content, we indirectly estimated the respective contributions of these two resources to various organs, at various times over the growth season. Fully heterotrophic and fully autotrophic plants from the same sites were used as references for delta C-13 and N content of biomass purely issuing from fungi and photosynthesis, respectively. 3. In four investigated populations, the biomass shifted from fully heterotrophic in young spring shoots to 80-100% autotrophic in leaves and fruits at fruiting time, suggesting that photosynthesis supported mostly fruiting costs. In addition, fungal colonization decreased in roots over this period. 4. Based on delta C-13 and N content, below-ground organs and young spring shoots from green (mixotrophic) individuals and spontaneous achlorophyllous variants (fully heterotrophic) displayed similar fungal C contributions. Similar fungal contributions were also found in shoots of individuals that were either sprouting (and thus partially photosynthetic) or dormant (and thus fully heterotrophic) in the previous years. Therefore, fungal C supported mostly young spring shoots and below-ground organs. 5. Although experimentally shaded plants had decreased contributions of photosynthetic C in shoots, experimentally defoliated plants showed no increase in fungal C contribution as compared with non-defoliated controls. Strikingly, these defoliated plants maintained the same seed production: they likely compensated defoliation by increasing stem and fruit photosynthesis. 6. Synthesis. We propose a falsifiable model of C resource allocation in mixotrophic orchids, where mycorrhizal fungi mostly support below-ground organs and survival, while photosynthesis mostly supports above-ground sexual reproduction, but not below-ground reserves. We discuss how this allocation pattern, where seed production depends on photosynthesis, complicates the evolutionary route to full heterotrophy in mixotrophic orchids.", "publicationTitle": "JOURNAL OF ECOLOGY", "publisher": "", "place": "", "date": "septembre 2014", "volume": "102", "issue": "5", "section": "", "partNumber": "", "partTitle": "", "pages": "1183-1194", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1111/1365-2745.12274", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0022-0477", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "C-13" }, { "tag": "N content" }, { "tag": "Stable isotopes" }, { "tag": "albino plants" }, { "tag": "dormancy" }, { "tag": "mycoheterotrophy" }, { "tag": "mycorrhizas" }, { "tag": "photosynthesis in the shade" }, { "tag": "plant-soil (below-ground) interactions" } ], "collections": [ "UN4ZBN6K" ], "relations": {}, "dateAdded": "2014-10-23T13:14:16Z", "dateModified": "2014-10-23T13:14:16Z" } }, { "key": "MKQX22N2", "version": 3, "library": { "type": "group", "id": 275408, "name": "LSE", "links": { "alternate": { "href": "https://www.zotero.org/groups/lse", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/275408/items/MKQX22N2", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/lse/items/MKQX22N2", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1721057, "username": "pya", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/pya", "type": "text/html" } } }, "creatorSummary": "Vega et al.", "parsedDate": "2014", "numChildren": 0 }, "data": { "key": "MKQX22N2", "version": 3, "itemType": "journalArticle", "title": "PTrees: A point-based approach to forest tree extraction from lidar data", "creators": [ { "creatorType": "author", "firstName": "C.", "lastName": "Vega" }, { "creatorType": "author", "firstName": "A.", "lastName": "Hamrouni" }, { "creatorType": "author", "firstName": "S.", "lastName": "El Mokhtari" }, { "creatorType": "author", "firstName": "J.", "lastName": "Morel" }, { "creatorType": "author", "firstName": "J.", "lastName": "Bock" }, { "creatorType": "author", "firstName": "J. -P.", "lastName": "Renaud" }, { "creatorType": "author", "firstName": "M.", "lastName": "Bouvier" }, { "creatorType": "author", "firstName": "S.", "lastName": "Durrieu" } ], "abstractNote": "This paper introduces PTrees, a multi-scale dynamic point cloud segmentation dedicated to forest tree extraction from lidar point clouds. The method process the point data using the raw elevation values (Z) and compute height (H = Z-ground elevation) during post-processing using an innovative procedure allowing to preserve the geometry of crown points. Multiple segmentations are done at different scales. Segmentation criteria are then applied to dynamically select the best set of apices from the tree segments extracted at the various scales. The selected set of apices is then used to generate a final segmentation. PTrees has been tested in 3 different forest types, allowing to detect 82% of the trees with under 10% of false detection rate. Future development will integrate crown profile estimation during the segmentation process in order to both maximize the detection of suppressed trees and minimize false detections.

Functional traits represent one of the main opportunities to bring new insights into the understanding of soil invertebrate responses to environmental changes. They are properties of individuals which govern their responses to their environment. As no clear conceptual overview of soil invertebrate trait definitions is available, we first stress that previously-described concepts of trait are applicable to soil invertebrate ecology after minor modification, as for instance the inclusion of behavioural traits. A decade of literature on the use of traits for assessing the effects of the environment on soil invertebrates is then reviewed. Trait-based approaches may improve the understanding of soil invertebrate responses to environmental changes as they help to establish relationships between environmental changes and soil invertebrates. Very many of the articles are dedicated to the effect of one kind of stress at limited spatial scales. Underlying mechanisms of assembly rules were sometimes assessed. The patterns described seemed to be similar to those described for other research fields (e.g. plants). The literature suggests that trait-based approaches have not been reliable over eco-regions. Nevertheless, current work gives some insights into which traits might be more useful than others to respond to a particular kind of environmental change. This paper also highlights methodological advantages and drawbacks. First, trait-based approaches provide complementary information to taxonomic ones. However the, literature does not allow us to differentiate between trait-based approaches and the use of a priori functional groups. It also reveals methodological shortcomings. For instance, the ambiguity of the trait names can impede data gathering, or the use of traits at a species level, which can hinder scientific interpretation as intra-specific variability is not taken into account and may lead to some biases. To overcome these shortcomings the last part aims at proposing some solutions and prospects.

Research has focused on phytoremediation and many have presented this technology as the process ideally combining efficiency, low cost and environmental acceptance. However, the applicability of phytoremediation on soils contaminated by bio-recalcitrant organic compounds, such as polycyclic aromatic hydrocarbons (PAH), has not yet proved as successful as expected. We propose here a review and discussion of the overall question of PAH status in soil and their potential for treatment. The limits and applicability of bioremediation technologies are discussed, and the specific beneficial effect of plants is objectively evaluated with a special interest to processes which lead to rhizoattenuation.

To investigate this, soil and leaf litter were sampled in the urban area of Naples, Italy and the collembolan community was analyzed using taxonomic and functional approaches. The results indicated that collembolan density was negatively affected by site pollution, and that species richness, diversity and evenness were positively affected by the organic matter content of the soil. Folsomia lawrencei was the most abundant species in sites with high metal contamination and low soil organic matter content, whereas Mesaphorura sp. and Parisotoma notabilis were the most ubiquitous taxa overall.

Their ecological reclamation by key members of the soil fauna, such as earthworms, is a promising way to ensure such services. However, literature which treats these animals as a biological agent of constructed Technosol functioning is very scarce. This work assesses the effects of the composition of a constructed Technosol (i.e. the proportions of the constituent materials) on earthworm (Lumbricus terrestris) surface cast production and composition, and to a lesser extent on earthworm survival and biomass. Earthworms were placed in laboratory microcosms made of different proportions of materials: green-waste compost (GWC) and thermally treated industrial soil mixed with paper mill sludge (TIS/PS), for 30 days. We found that 25% of GWC on the surface and 75% of TIS/PS below was the most beneficial composition in that it gave the highest body mass gain. Furthermore, this composition generated a moderate surface cast production compared to other compositions and an increase in microorganism activity and number compared to non-ingested by earthworm soil. This composition also led to casts with bacteria of diverse morphologies and largest microaggregates compared to compositions without GWC, resulting from the ingestion and mixing of the two materials in the earthworm gut. However, earthworms did not modify the carbon contents of surface casts. This laboratory approach was a necessary step before field assessment of ecological reclamation by earthworms. From a soil engineering point of view, this contributes to better-managed soil construction for ecological reclamation. (C) 2014 Elsevier B.V.

Results showed that the profile was composed of a succession of sub-horizontal layers arranged in two groups according to their structure and composition, linked to the composition of the industrial effluent. Group 1 was composed of iron-, carbonate-and aluminosilicate-rich layers exhibiting a compact structure. Group 2 contained manganese-rich layers with a friable structure.

At [Cd] (T) = 1 mu M, when [EDTA] (T) /[Cd] (T) < 1, the model indicated that Cd uptake was predominantly due to the absorption of free Cd2+, whose pool was replenished by the dissociation of Cd-EDTA. When [EDTA] (T) /[Cd] (T) > 1, the low Cd uptake was mostly due to Cd-EDTA absorption. In soil spiked with 5 mg Cd kg(-1), Cd uptake was not affected by the various EDTA additions, because of the buffering capacity of the soil solid phase.

Research has focused on phytoremediation and many have presented this technology as the process ideally combining efficiency, low cost and environmental acceptance. However, the applicability of phytoremediation on soils contaminated by bio-recalcitrant organic compounds, such as polycyclic aromatic hydrocarbons (PAH), has not yet proved as successful as expected. We propose here a review and discussion of the overall question of PAH status in soil and their potential for treatment.

This work assesses the effects of the composition of a constructed Technosol (i.e. the proportions of the constituent materials) on earthworm (Lumbricus terrestris) surface cast production and composition, and to a lesser extent on earthworm survival and biomass. Earthworms were placed in laboratory microcosms made of different proportions of materials: green-waste compost (GWC) and thermally treated industrial soil mixed with paper mill sludge (TIS/PS), for 30 days. We found that 25% of GWC on the surface and 75% of TIS/PS below was the most beneficial composition in that it gave the highest body mass gain. Furthermore, this composition generated a moderate surface cast production compared to other compositions and an increase in microorganism activity and number compared to non-ingested by earthworm soil. This composition also led to casts with bacteria of diverse morphologies and largest microaggregates compared to compositions without GWC, resulting from the ingestion and mixing of the two materials in the earthworm gut. However, earthworms did not modify the carbon contents of surface casts. This laboratory approach was a necessary step before field assessment of ecological reclamation by earthworms. From a soil engineering point of view, this contributes to better-managed soil construction for ecological reclamation. (C) 2014 Elsevier B.V.

Hypereutric Cambisols dominate upslope; Cambic Vertisols and Fluvic Cambisols occur downslope. The soil mineralogy showed abundance of primary serpentine all over the sequence. It is predominant upslope but secondary smectites dominate in the Vertisols. Free Fe-oxides are abundant in all soils but slightly more abundant in the upslope soils. Whereas serpentines hold Ni in a similar and restricted range in every soil (approx. 0.3 %), Ni contents in smectites may vary a lot and Mg-rich and Al-poor smectites in the Vertisol could hold up to 4.9 % Ni. Ni was probably adsorbed onto amorphous Fe-oxides and was also exchangeable in secondary smectites. High availability of Ni in soils was confirmed by DTPA extractions. However, it varied significantly along the toposequence, being higher in upslope soils, where Ni-bearing amorphous Fe-oxides were abundant and total organic carbon higher and sensibly lower downslope on the Vertisols: Ni-DTPA varied from 285 mg kg(-1) in the surface of soil I (upslope) to 95.9 mg kg(-1) in the surface of Fluvic Cambisols. Concentration of Ni in Alyssum murale shoots varied from 0.7 % (Hypereutric Cambisols) to 1.4 % (Hypereutric Vertisol). Amazingly, Ni uptake by A. murale was not correlated to Ni-DTPA, suggesting the existence of specific edaphic conditions that affect the ecophysiology of A. murale upslope.", "publicationTitle": "ENVIRONMENTAL MONITORING AND ASSESSMENT", "publisher": "", "place": "", "date": "juillet 2014", "volume": "186", "issue": "7", "section": "", "partNumber": "", "partTitle": "", "pages": "4431-4442", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1007/s10661-014-3709-6", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0167-6369", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Alyssum murale" }, { "tag": "Bioavailability" }, { "tag": "Hyperaccumulation" }, { "tag": "Serpentine soil" }, { "tag": "Soil mineralogy" } ], "collections": [], "relations": {}, "dateAdded": "2014-07-23T12:03:29Z", "dateModified": "2014-07-23T12:03:29Z" } }, { "key": "V3TGNRI5", "version": 2, "library": { "type": "group", "id": 275408, "name": "LSE", "links": { "alternate": { "href": "https://www.zotero.org/groups/lse", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/275408/items/V3TGNRI5", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/lse/items/V3TGNRI5", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1721057, "username": "pya", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/pya", "type": "text/html" } } }, "creatorSummary": "Rees et al.", "parsedDate": "2014-01", "numChildren": 0 }, "data": { "key": "V3TGNRI5", "version": 2, "itemType": "journalArticle", "title": "Short-term effects of biochar on soil heavy metal mobility are controlled by intra-particle diffusion and soil pH increase", "creators": [ { "creatorType": "author", "firstName": "F.", "lastName": "Rees" }, { "creatorType": "author", "firstName": "M.

The effects of biochar on the mobility of metals in soils are, however, poorly understood. To identify the predominant processes, we focused on (i) a possible kinetic limitation by transport in biochar particles, (ii) the evolution of biochar mineral phases and (iii) the effect of biochar on soil pH. Batch experiments were conducted to measure the sorption kinetics of copper (Cu), cadmium (Cd) and nickel (Ni) and the sorption-desorption isotherms for lead (Pb), Cu, Cd, zinc (Zn) and Ni in a wood-derived biochar. Sorption data were then compared with extraction test results using biochar with one acidic and one basic soil contaminated by Zn, Cd and Pb. Kinetic results showed that biochar particle sizes controlled metal sorption rate despite a similar specific surface area, which indicated a limitation by intra-particle diffusion. Isotherms showed a partially reversible sorption to biochar following the order Pb>Cu>CdZn>Ni, which we explained primarily by the (co)precipitation of metals or their adsorption on specific biochar mineral phases. Effective metal immobilization was observed with biochar in both contaminated soils but could not be predicted from the sorption isotherms. This immobilization appeared to be governed by the soil pH increase, which induced a greater retention of metals on soil particles. Short-term effects of biochar on contaminated soils may therefore be controlled by diffusion in biochar particles and by soil alkalinization processes.", "publicationTitle": "EUROPEAN JOURNAL OF SOIL SCIENCE", "publisher": "", "place": "", "date": "janvier 2014", "volume": "65", "issue": "1, SI", "section": "", "partNumber": "", "partTitle": "", "pages": "149-161", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1111/ejss.12107", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1351-0754", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2014-07-23T12:03:29Z", "dateModified": "2014-07-23T12:03:29Z" } }, { "key": "9HNMQRSK", "version": 2, "library": { "type": "group", "id": 275408, "name": "LSE", "links": { "alternate": { "href": "https://www.zotero.org/groups/lse", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/275408/items/9HNMQRSK", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/lse/items/9HNMQRSK", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1721057, "username": "pya", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/pya", "type": "text/html" } } }, "creatorSummary": "Zhang et al.", "parsedDate": "2014", "numChildren": 0 }, "data": { "key": "9HNMQRSK", "version": 2, "itemType": "journalArticle", "title": "SELECTION AND COMBUSTION OF NI-HYPERACCUMULATORS FOR THE PHYTOMINING PROCESS", "creators": [ { "creatorType": "author", "firstName": "Xin", "lastName": "Zhang" }, { "creatorType": "author", "firstName": "Vivian", "lastName": "Houzelot" }, { "creatorType": "author", "firstName": "Aida", "lastName": "Bani" }, { "creatorType": "author", "firstName": "Jean Louis", "lastName": "Morel" }, { "creatorType": "author", "firstName": "Guillaume", "lastName": "Echevarria" }, { "creatorType": "author", "firstName": "Marie-Odile", "lastName": "Simonnot" } ], "abstractNote": "Ni recovery from serpentine soils by phytomining has proved feasible. Phytomining involves the crop of hyperaccumulating plants with high Ni contents and the valorization of Ni by pyro or hydrometallurgical process. In order to evaluate the Ni content of different plants, we analyzed the organs of 14 hyperaccumulators from three genera: Alyssum, Leptoplax and Bornmuellera. The highest concentration was recorded in the leaves of Leptoplax (34.3 +/- 0.7 mg g(-1) DM). Additionally, we investigated biomass combustion which is the first step of the process we designed to obtain a nickel salt. We showed that temperature and duration were important parameters to ensure a good quality of ashes. At the bench scale, the best conditions were 550 degrees C and 3 h.
