    Authors: Chevaldonné, P.; Sket, B.; Marschal, C.; Lejeusne, C.; +1 Authors

    Dark littoral submarine caves can act as enclaves of the deep aphotic zone in shallow coastal areas, and their survey has revealed the existence of a very particular fauna of specialized and poorly known organisms among which crustaceans are particularly well represented. In these particular habitats, the use of conventional sampling techniques, such as hand nets, is often not recommended since they disturb bottom sediments causing hazardous situations to scientific divers. The use of baited traps, while technically possible, is not. always practical is such remote habitats. The present work describes a simple and inexpensive manual device that can be operated by divers ill submarine caves and other cryptic habitats to recurrently catch small motile organisms such as mysid crustaceans, caridean shrimps, or even gobiid fishes. This small suction bottle derived and improved from the original "Sket bottle" design considerably reduces the risks of disturbing the cave's bottom sediment and can be easily operated using a single hand. The described sampling device can also be easily used outside caves, in a variety of particular habitats, e.g., rubble filled bottoms, branching coral reefs, cracks, and small holes on rocky surfaces, in which small motile organisms usually escape from traditional sampling gears, e.g., fishnets and traps, or simply go unnoticed by researchers during sampling. info:eu-repo/semantics/publishedVersion

    International audience; Collembola is an abundant group of soil organisms playing a major role on litter decomposition process and nutrient cycling in forest ecosystems. Habitat structure strongly influences Collembola assemblages as plant litter physical characteristics and quantity provide structural niches and determine the outcome of their interactions with predators. Collembola are also extremely sensitive to environmental conditions such as soil temperature that control their demographic parameters and activity. In this context, increasing temperature with the ongoing climate change can have strong impact on Collembola assemblages and their responses to predation either directly by altering their behaviour or indirectly by altering their habitat structure. We therefore examined how the increase of temperature combined to the decrease of specific leaf area (SLA, a major functional plant trait) of the European common oak (Quercus robur L.) and the presence of a centipede predator (Chilopoda Lithobiidae) will affect the abundance of Folsomia candida (Collembola Isotomidae) in a 5-week microcosm experiment. Increasing temperature, decreasing SLA and presence of centipede altered F. candida abundance. We observed a significant temperature × predation interaction suggesting differential effects of increasing temperature on F. candida abundance with and without predator. We also observed a significant SLA × predation interaction highlighting that lower SLA decreases F. candida abundance only in predator presence. Finally, our findings evidenced that increasing temperature and decreasing SLA amplify the negative effect of centipede predation on F. candida abundance, suggesting that both direct and indirect effects of climate change would conjointly strengthen the top-down control of predators on preys.

    International audience; A green roof is an option for improving a building thermal comfort. The investigation is here performed within the specific climate context of Reunion Island in south hemisphere. This type of roof system involves choice difficulties for plant species that are more favorable to establish that comfort. The objective of this work is to simulate the dynamic behavior of this system towards external requests in wet tropical zones and vis-à-vis influences of certain number of physical parameters related to this system. As long as possible, authors used the electrical analogy method to establish a mathematical model associated to the studied system. Based on this model, a Matlab computing code was finalized. Weather data of Reunion Island were used for simulations; the green roof potential and benefit were highlighted by surveying the temperature gain and the heat flux crossing the roof as well as the energy saving performance. Furthermore, the energy consumption being surveyed while doing sensitivity analysis with Fourier Amplitude Sensitivity Test method, the most influential parameters of the model were identified. Full scale experimental results are provided and consisting in monitoring green roof on the top of a public building. According to the results, we can assert that the green roof decreases heat flux entering through the roof during the day and restrains the restoration of accumulated heat at night. Indeed, the support on which the plantation ground bases affects the building thermal insulation. The experimental data are also conducted to prove the effectiveness of thermal insulation by green roofs in reducing temperature in the building between 5°C and 7°C in relation to plants type and the canopy Leaf Area Index (LAI). A comparison of experimental values and model results is done. Among other uses, this code can be used as a tool for choosing the plants and the drain materials to be experimented on the green roof. The results offer hints to optimize the design and thermal performance of extensive green roofs.

    Authors: Brochier, Jacques;

    International audience; Culling profiles are important and widely used statistical objects in archaeozoological studies. Topics such as site specific use (like seasonal cave penning), sites complementarity, site status (“producer” versus “consumer” sites), specialized production strategies (milk, meat and/or wool strategies) and, more generally, long term evolution of pastoral practices rely strongly upon this kind of data. Here we show that a long lasting and widespread error in the construction and interpretation of culling profiles sheds doubts on the validity of the economic, territorial and breeding practice models proposed in old world recent prehistory.

    International audience; This contribution brings to a close a special issue of Hydrology and Earth System Sciences concerning the assessment of nitrogen dynamics in catchments across Europe within a semi-distributed Integrated Nitrogen model for multiple source assessment in Catchments (INCA). The wide range of issues involved in relation to hydrology and within-catchment processes, scale (from small catchments to major river basins), climate (from sub-arctic to Mediterranean regimes) and pollution (atmospheric, agricultural and urban sources) is outlined. Consideration is then given to how well the model has performed and future research requirements are outlined. Keywords: nitrogen, nitrate, ammonium, organic nitrogen, catchments, streams, rivers, river basins

    Authors: Escobar Gutierrez, Abraham, A.; Combe, Laurette;

    International audience; The objective of this work was to describe the dynamics of senescence of field-grown maize from silking to harvest, at both leaf and plant level. At the leaf level, the dynamics of symptoms of senescence were considered on each leaf taken individually and described according to zones from the tip to the base of the leaf lamina. At the whole plant level, foliar ranks were each considered as an entity to describe the time course of senescence. To this end, we use a database built-up from field trials conducted during three consecutive years (1994-1996) and thus undergoing variable meteorological and soil water conditions. Leaf chlorophyll content was estimated using two different methods based on the optical properties of the leaves. In Trial I, chlorophyll estimates were based on leaf optical density measured with a MacBeth TR-924 densitometer. In Trial II and Trial III, chlorophyll estimations were based on measurement using a hand-held Minolta SPAD-502 device. In Trial II and Trial III, chlorophyll fluorescence analyses under filed conditions were performed. These analyses focused on the photosystem II (PSI!) maximum efficiency (Fv'/Fm') parameter in the light-adapted state. Measurements were done with a Waltz PAM-2000 portable fluorometer. We report detailed descriptions of the spatio-temporal dynamics of these indicators of senescence. We found that, after silking, a strong relationship exists between available water and leaf chlorophyll content. Further, the maximum efficiency of PSII decreased faster in maize plants undergoing low available soil water than in irrigated plants. The rank of a leaf is determinant of the time for the beginning of the decline in both chlorophyll content and maximum efficiency of PSII. At plant and leaf level, the onset of senescence was marked by a decrease in chlorophyll content that was not concomitant with a dramatic decrease in the maximum efficiency of PSII. Our analyses suggest that a non-linear functional relationship could exist between these two parameters during monocarpic senescence. In the mean time, the results presented in this paper could be used to refine the senescence related modules in plant and crop models.

  • Authors: Lecoeur, J.; Wery, J.; Turc, Olivier; Tardieu, Francois, F.;

    We have followed the expansion of individual pea leaves from initiation to maximum area, over two markedly different periods. During the first one (2/3 of total leaf development time), cell production occurred while cell and leaf expansions were slow. Rapid expansion (95% of total) occurred for a second period lasting 1/3 of total development time, whereas cell division was virtually completed. Water deficits of 15 d were applied during either slow or rapid expansion, and characterized by measurements of soil water potential, stomatal conductance, leaf water potential and xylem [ABA]. Plants which experienced water deficit during the slow expansion period had markedly reduced expansion during the second period (i.e. 1 or 2 weeks after cessation of deficit), while all variables characterizing water status were returned to the level of the control. This 'after effect' was accounted for by a reduced cell number per leaf, while individual cell area was not affected. In contrast, water deficit occurring during rapid leaf expansion immediately reduced leaf expansion via cell area, without affecting cell number per leaf. These experiments indicate a role, in the response to water deficits, for events occurring very early in the development of pea leaves, while leaf expansion is too slow to be measured with macroscopic methods. This role would be accounted for by cell production during the first 2/3 of leaf development while cell expansion would account for changes in the area of leaves experiencing a later stress. These results suggest that long-term temporal analysis may be essential in the study of dicot leaf expansion compared to monocot leaves where temporal analysis can be inferred from spatial analysis.

    International audience; The cellular and molecular adaptations of non-model woody species to environmental changes are still poorly understood. We have cloned and characterised a novel non-symbiotic hemoglobin from oak roots (QpHb1) which exhibits a specific cellular distribution in the root. The QpHb1 gene is strongly expressed in the protoderm and the protoxylem cells in two Quercus species (Q. petraea and Q. robur) with contrasting adaptive potential to drought and flooding. The constitutive expression of QpHb1 in both oak species in specific root tissues combined with the reported presence of nitric oxide in the same tissues and its potential for protein S-nitrosylation could support a role for non-symbiotic hemoglobins in signalling changes in the root environment and/or in controlling some aspects of root development.

    Variations du coût de construction associées au renouvellement de la surface foliaire chez de jeunes plants de deux espèces sympatriques de forêt tempérée (Acer platanoides L. et Fraxinus excelsior L.) le long d'un gradient de lumière. Le renouvellement des feuilles et des structures nécessaires à leur maintien (l'ensemble correspondant à la tige feuillée) représente chaque année un coût pour les plants. La contribution de la composition biochimique (coût de construction des tissus, CC) et des caractéristiques morphologiques (répartition de la biomasse, masse des feuilles par unité de surface, LMA) aux changements du coût associé à l'étalement des feuilles (coût de construction de la tige feuillée, par unité de surface foliaire, CCA) a été étudiée chez de jeunes plants de Acer platanoides L. et Fraxinus excelsior L. croissant dans un gradient naturel de lumière sous un couvert forestier. Une diminution de LMA avec l'ombrage et des modifications de répartition de biomasse au profit des feuilles et des pétioles et au détriment de la tige expliquent la forte diminution de la masse de la tige feuillée de l'année par unité de surface foliaire (SMA), et l'essentiel de la plasticité observée pour CCA de la tige feuillée chez les deux espèces. En plus, une diminution du coût de construction des feuilles chez A. platanoides contribue également à la diminution de CCA de la tige feuillée avec l'ombrage chez cette espèce. Le coût de construction des feuilles est positivement corrélé à LMA chez F. excelsior, positivement corrélé à LMA et à l'absorbance de l'épiderme dans l'UV (AUV) chez A. platanoides. CC des feuilles est négativement corrélé au contenu en cendre chez les deux espèces. La forte corrélation négative entre AUV et le contenu en azote pourrait tamponner les variations de CC des feuilles chez F. excelsior. The yearly renewal of leaves and their holding organs (the leafy shoot) represent an energetic cost for saplings. The contribution of both biochemical (tissue construction cost, CC) and morphological traits (biomass partitioning and leaf mass per unit area, LMA) to the cost associated with leaf area renewal (construction cost of the leafy shoot per unit leaf area, shoot CCA) was studied in saplings of Acer platanoides L. and Fraxinus excelsior L. growing in a natural light gradient below forest canopy. Decrease in LMA with shade and change in biomass partitioning from stems towards leaves and petioles accounted for the strong decrease in mass per unit area of the leafy shoot (SMA) with shade and for most of the plasticity of shoot CCA in both species. In addition, a decrease in leaf CC in A. platanoides also contributed to the overall decrease of shoot CCA with shade in this species. Leaf CC was positively correlated with LMA in F. excelsior, positively correlated with both LMA and epidermal absorbance of UV (AUV) in A. platanoides. Leaf CC was negatively correlated with ash content in both species. The strong negative correlation between AUV and nitrogen content might have damped variations in leaf CC in F. excelsior.

    ABSTRACTSoil flooding is an environmental constraint that is increasingly important for forest ecosystems, affecting tree growth and regeneration. As a result, selection pressure will alter forest diversity and distribution by favouring tree species tolerant of soil oxygen deprivation. Sessile and pedunculate oaks are the most abundant oak species and they exhibit a strong differential tolerance to waterlogging. In order to gain some understanding of the mechanisms of tolerance of both species to hypoxia, we undertook the characterization of the physiological, morphological, cellular and molecular responses of both species to flooding stress. Our results indicate that pedunculate oak, the more tolerant species, succeeded in maintaining its growth, water status and photosynthetic activity at a higher level than sessile oak. Furthermore, pedunculate oak developed aerenchyma in its root cortex as well as adventitious roots. The later exhibited a strong accumulation of class1 non‐symbiotic haemoglobin localized by in situ hybridization in the protoderm and in some cortical cells. In conclusion, the higher tolerance of pedunculate oak to flooding was associated with an enhanced capacity to maintain photosynthesis and water homeostasis, coupled with the development of adaptive features (aerenchyma, adventitious roots) and with a higher expression of non‐symbiotic haemoglobin in the roots.
