The total concentrations of trace elements in soils results from natural and anthropic factors. Knowledge of natural distribution (e.g. bio-geochemical background) helps assessing the impacts of human activities in terms of contaminations. But the processes generated by the modifications of the soil environment may also affect the form of a trace element, that is its distribution through various pools. We investigated the chemical speciation of some metallic trace elements (Cu, Zn, Cr, Ni, Pb, Co, Cd) in soils from various land-use environment: “natural” soils under forest, “typical” cultivated soils, kitchen-garden soils, soils developped on geogenic anomalies and on contaminated areas. The analysis protocol aims at identifying different pools from their reaction to various extraction phases, ordered by increasing intensity in a single sequence. The different fractions are so-called soluble, linked to carbonates, to organic matter, to manganese oxides, to weakly cristallized Fe-Al oxides, to well-cristallized oxides, and residual. The “available” and total fractions have also been measured. The results stress the fact that the comparisons are difficult from one situation to another because each one represents a particular case of human activity without a common logic. The relationships with the classical pedological parameters are therefore difficult to generalize. However some relationships between elements have been found inside the various types of land use, which could be usefull in the risk assesment of transfers from soils to plants. [less ▲]

In this paper, the modifications that have been recently introduced in the parametric fire model of Eurocode 1 are presented. The reasons behind these modifications are given. Some Problems that have been discovered in the present formulation are highlighted, namely the fact that the model is not continuous and the fact that the heat release of wood that has been used for the calibration of the model is not consistent anymore with the value that is now recommended in the Eurocode. A proposal is made that makes the model continuous. A new calibration of this modified model has been made on the base of the now recommended value of the heat release of wood with comparison to the results of some 50 full scale experimental fire tests.

At our remote study site in central Colorado, the population size of tiger salamanders (Ambystoma tigrinum nebulosum) has fluctuated cyclically over the past 20 years from fewer than 100 to over 5000 individuals. Comparative data between ponds with and without salamanders, and experimental studies suggest that this species is a keystone predator on benthic and planktonic prey communities. Here we present long-term community data that reveal taxon- and habitat-specific correlations in the population size of benthic and planktonic prey with fluctuations in salamander populations. Changes in the abundance of planktonic, but not benthic invertebrates in temporary habitats were correlated with fluctuations in the abundance of salamanders. In permanent ponds, we observed order-of-magnitude changes in benthic biomass that are negatively correlated with salamander abundance. Among the large-bodied and potentially most vulnerable benthic invertebrates (odonates, caddisflies, beetles, water bugs), several species exhibited negatively coupled cycles, but others fluctuated little or out of phase with changes in salamander abundance. The absence of major shifts in benthic community composition in permanent ponds is probably a result of conflicting predation pressures exerted by different year classes of salamanders. Salamander gut samples suggest that ontogenetic shifts in diet might explain why cyclic fluctuations in the abundance of this predator had only minor impacts on benthic community composition despite having major effects on invertebrate biomass.

The mechanisms underlying population fluctuation have been well studied in mammals and insects but less research has focused on amphibians. Yet, the current global decline of amphibians equires that we understand these mechanisms, and be able to distinguish between anthropogenically induced declines and natural population fluctuations. We have followed a marked population of the Arizona tiger salamander, Ambystoma tigrinum nebulosum, for over 16 years during which time the population has completed two “boom and bust” cycles, generated by a dominant cohort that appears to suppress larval recruitment until it senesces. We tested two hypotheses for this suppression, cannibalism and resource depression, using a series of meso- and microcosm experiments. We found significant lethal and sublethal (behavior, diet, growth rates) effects of cannibalism by large larvae and paedomorphic adults on hatchling and 1st-year larvae, suggesting that both cannibalism and the threat of cannibalism are important in cohort suppression. Resource depression experiments revealed that paedomorphic adults did not affect larval survival, diet, or growth, despite reduced prey densities, because paedomorphs mainly reduced large bodied prey, whereas hatchlings fed primarily on smaller benthic and zooplanktonic invertebrates. Future experiments will determine how hatchlings are impacted by boom cohorts that are more similar in size and diet. Our results lend insight into the mechanisms underlying fluctuations in this population, and suggest that a better understanding of natural population fluctuations will aid amphibian conservation efforts.

Repeated imaging of Jupiter's aurora has shown that the northern main oval has a distorted 'kidney bean' shape in the general range of 90-150o System III longitude, which appears unchanged since 1994. While it is more difficult to observe the conjugate regions in the southern aurora, no corresponding distortion appears in the south. Recent improved accuracy in locating the auroral footprint emission of Io has provided new information about the geometry of Jupiter's magnetic field in this and other areas. The persistent pattern of the main oval implies a disturbance of the local magnetic field, and the increased latitudinal separation of the locus of the Io footprint from the main oval implies a locally weaker field strength. The most recent images obtained with the Hubble Space Telescope Advance Camera for Surveys (ACS) allow us to complement previous observations with the location of the auroral footprints of Io, Europa, and Ganymede in the region of interest. Their footpaths vary in parallel and form a kink in the 90-150° S3 sector which strongly suggests the presence of a magnetic anomaly in this region. [less ▲]

Within the periurban areas of big cities, soils are often contaminated by heavy metals spread by human activity: atmospheric fallouts due to industry and traffic, recycling of urban wastes (directly or after water treatment), fertilizers and pesticides used in agriculture… This is, among others, verified in the surroundings of Kunming (Yunnan, PR China) and Lille (Nord-Pas de Calais, France), areas with high density of population and traditional metallurgical industries. These areas have also intensive agricultural activities characterized by important vegetable productions, and are generally known as the "green belts" of the cities. These cultures, with short vegetative period, need high biodisponibility of nutrients, biodisponibility which may also occur for other unwanted elements existing in the soil, such as heavy metals. For evident human health reasons the quality of the crops must be ensured and their heavy metal content kept as low as possible, at least under the values of relevant legal thresholds. Thus, vegetables are particularly sensitive to the presence of heavy metals in the soils where they are growing. It is therefore necessary to manage these soils in order to preserve public health or, more basically, the income of the farmers, as contaminated vegetables would not be marketable. Thus, for these large areas contaminated by diffuse pollution, bioremediation looks to be appropriate. But the kind of the bioremediation which will be applied has to be adapted to the severity of the soil pollution and to the intended land use. In this project, we have assessed the contents of Pb, Cd, Zn and Cu of soils and vegetables within the Chenggong county (near Kunming), and compared the results to the already known situation of the surroundings of two lead and zinc smelters located close to Lille. Then goals and ways of bioremediation have been discussed and the first steps of implementation experimented. [less ▲]

The electromagnetic interaction between Io and Jupiter's magnetic field leads to single or multiple UV spots in both jovian hemispheres. Variations of the multiplicity of the spots and the inter-spots distances have been observed and are linked to the position of Io in its plasma torus. These morphological changes have a timescale of a few hours. We have studied the footprint evolution with a time resolution of a few tens of seconds using the HST/STIS camera in the time-tag mode. This approach resulted in an evaluation of the impact of the rapid evolution of the jovian magnetic field lines when measuring the dimensions of the spots with a longer exposure time. More basically, evidence of strong brightness variations of the main spots (up to 40%) have been observed with a typical growth time of 1 minute. Finally, unexpected simultaneous fluctuations of both primary and secondary spots have also been found in the southern hemisphere. In conclusion, the characterisation of the variations mentioned herein provides clues for a complex and rapidly evolving energetic electrons precipitation mechanism. [less ▲]

The mechanisms underlying population fluctuation have been well studied in mammals and insects but less research has focused on amphibians. Yet, the current global decline of amphibians requires that we understand these mechanisms, and be able to distinguish between anthropogenically induced declines and natural population fluctuations. We have followed a population of the Arizona tiger salamander, Ambystoma tigrinum nebulosum, over 16 years and through two cycles of population fluctuation, which is typified by the production of “boom” cohorts followed by suppression of larval recruitment by paedomorphic adults in this cohort. We tested two hypotheses for this suppression, cannibalism and resource depression, using a series of meso- and microcosm experiments. We found significant direct (mortality) and indirect (behavior, diet, growth rates) effects of cannibalism by larger larvae and paedomorphic adults on hatchling and 1st-year larvae, suggesting that both cannibalism and the threat of cannibalism play a large role in suppression of larval cohorts. In contrast, paedomorphic adults showed no substantial effects on larval survival, diet, or growth via resource depression, in part because paedomorphic adults reduced availability of large benthic invertebrates, while hatchlings fed primarily on smaller benthos and zooplankton. However, current experiments suggest that hatchlings can be impacted by cohorts of larvae that are more similar in size and diet. Our results lend insight into the mechanisms underlying fluctuations in this population, and suggest that a better understanding of natural population fluctuations will aid amphibian conservation efforts.

We present the results of a statistical analysis of the location of commonly-occurring auroral features in Saturn's southern polar ionosphere. Using a magnetospheric model, modified for Saturn from a data-based terrestrial model (Tsyganenko, 1996), we estimate the region in the equatorial plane of the outer magnetosphere that maps to the observed aurora. We then discuss the possible magnetospheric processes that may cause these auroral emissions. [less ▲]

Au Cameroun, le processus de la gestion durable des forêts a conduit une société d'exploitation forestière industrielle à procéder depuis quelques années, en partenariat avec des institutions de recherche locales ou internationales, à des études scientifiques d'espèces identifiées comme vulnérable dans ses concessions. A ce titre, la détermination de techniques d'interventions sylvicoles pragmatiques ainsi que l'écologie d'espèces telles que l'iroko, Milicia excelsa sont étudiées afin de comprendre et de remédier au faible niveau de régénération naturelle. Les observations portent d'une part sur les performances de fructification (phénologie, pluie de graine, germination) et de dispersion des semences, et d'autre part, sur la dynamique de populations naturelles de juvéniles. Etant donné qu'une faible performance de régénération peut être due à la consanguinité, elle-même résultant de la raréfaction des populations, il est prévu également une analyse de la diversité génétique locale. Parallèlement, des essais de plantations permettent de juger des effets de différents facteurs abiotiques ou biotiques sur la dynamique des plantules. [less ▲]
