Abstract

Background: Grasslands provide a wide range of ecosystem services (ESs). However, there is currently no method for easily diagnosing the level of ESs produced. Our aim was to develop ES indicators based on botanical surveys, which are readily available data and integrative of grassland spatiotemporal variability. Methods: Based on academic knowledge and expertise, we identified several simple vegetation criteria that we aggregated using a multicriteria analysis tool to construct indicators of the level of ESs provided by grasslands. In this study, the indicators were calculated from over 2000 botanical surveys spread over a wide biogeographical gradient. Results: Analyses of correlation between the various indicators show that “forage supply” and “diversity conservation” were not correlated. “Forage availability” and “nitrogen availability for the vegetation” were positively linked together and negatively linked to the robustness of the plant community to extreme events. A temporal approach highlights that the “biodiversity conservation” score decreased from 1970 to 2010 and that “nitrogen availability for the vegetation” was lower in 1970 and 1980 than in 2000 and 2010. Conclusions: These results show that our aggregation method based on a large data set of botanical surveys could be appropriate for studying temporal dynamics of ESs.

Abstract

The current pollinator decline is a major issue, notably because one-third of the world agricultural production depends on pollination. However, quantifying whether the loss of some pollinators translates into less efficient pollination remains challenging, particularly at the scale of farmland territories, which is a relevant scale for action. On the one hand, clear links have been established between the abundance and diversity of pollinators and pollination efficiency only over relatively small areas, because time-consuming experimental methods prohibit studies over broader areas. On the other hand, nationwide or continentwide indices exist but they either measure potential pollination only or have not been validated against other metrics characterizing pollinators or pollination.The aim of our study was to assess the relevance of two pollination indicators developed at national or broader scale, to characterize pollination over a 950-ha farmland territory of field crops (Fénay platform near Dijon, France). We specifically evaluated the realized pollination service indicator, based on cropyields and their dependence on pollinators, and the potential pollination indicator simulated by the InVEST model, based on land use and landcover as proxies for potential floral and nesting resources.We examined the spatiotemporal variation of these indicators over the Fénay area between 2005 and 2019, their environmental correlates (farming practices, landscape, and weather) and how they were related to each other.Our results suggest that the two indicators designed for large spatial extent can prove useful within farmland territories: both indicators exhibit significant variation across the study area, some of which could be related with environmental variables known to influence pollinators. For example, the spatial variation in the realized pollination service index correlates with farming practices, e.g. less efficient pollination in plots with more herbicide use. No correlation with the distance to the nearest semi-natural element was found, which contradicts results from previous studies at the field scale. The temporal variation in the pollination service index correlates negatively with the duration and intensity of summer heat waves. The potential pollination indicator will be compared with the realized pollination indicator, and in the future with field measurements of pollination efficiency for cross validation.

Abstract

Simple Summary Permanent grasslands are main habitats for many plant species and pollinators. Their destruction as well as their intensification has a major impact on plant and pollinator biodiversity, which has a cascading effect on pollination. However, we lack an understanding of these effects, thereby limiting our ability to predict them. In this review, we synthesised the literature on the mechanisms behind this cascade to provide new insights into the relationship between land-use intensification and pollination. By matching functional traits that mediate the relationship between the two trophic levels, we identified major knowledge gaps about how land-use intensification affects plant–pollinator interactions and how it favours plants with generalised floral traits, which are likely harmful to pollination. Abstract Permanent grasslands are suitable habitats for many plant and animal species, among which are pollinating insects that provide a wide range of ecosystem services. A global crisis in pollination ecosystem service has been highlighted in recent decades, partly the result of land-use intensification. At the grassland scale, however, the underlying mechanisms of land-use intensification that affect plant–pollinator interactions and pollination remain understudied. In this review, we first synthesise the literature to provide new insights into the relationships between land-use intensification and pollination by using matching community and interaction traits. We then identify knowledge gaps and summarise how land-use intensification of grassland influences floral traits that may in turn be associated with modifications to pollinator matching traits. Last, we summarise how these modifications may affect pollination function on permanent grasslands. Overall, land-use intensification may lead to a shift in flower colour, a decrease in mean nectar tube depth and a decrease in reward production and pollen quality at the community level. This, in turn, may generate a decrease in pollinator mouthparts length and body size, that may favour pollinators that require a low amount of floral reward. We found no study citing the effect of land-use intensification on volatile organic compounds emitted by flowers despite the importance of these molecules in pollinator community composition. Overall, our review highlighted major knowledge gaps about the effects of land-use intensification on plant–pollinator interactions, and suggests that land-use intensification could favour plants with generalised floral traits that adversely affect pollination.

Abstract

International audience; The invasive pest Drosophila suzukii (Matsumura, 1931) is a fruit fly native to Asia that infests a wide variety of cultivated and wild fruits, causing important damages on agricultural production. Wild plant species are major reservoirs for D. suzukii populations but their infestation rates varies greatly among geographical areas. This heterogeneity could partly be caused by a heterogeneity of environmental conditions acting across different spatial scales. This study aimed to disentangle the relative roles of macroclimatic, landscape and local factors that could affect the success of D. suzukii infestation of elderberry fruits (Sambucus nigra), a major and widespread host plant along climatic gradients. We collected elderberry fruits and measured vegetative and reproductive life traits of the plants in 215 sites distributed in 13 regions from North to South France during summer 2020. We counted the number of D. suzukii emerging from sampled fruits and tested for an effect of macroclimatic, landscape and local abiotic and biotic variables, as well as plant traits using linear mixed models with region as random factor. Latitude and mean maximum temperature had respectively the strongest positive and negative effects on mean infestation rates across regions (R = 0.761, p = 0.003 and R = −0.758, p = 0.004). Mixed models also showed that fruit infestation rate increased with the number of mature fruits within corymb and with forest cover in a 100 m radius around sampling sites and decreased with mean maximum temperature. The latitudinal and climatic clines in infestation rates suggests that D. suzukii population size might vary greatly among geographic regions. Our results also suggest that population sizes are larger in the presence of semi-natural habitats such as forest patches in the surrounding landscape. Our work contributes to enhancing our understanding of D. suzukii ecology, which is important to predict how infestation rates might change in the context of global climatic changes.

Abstract

Many recent studies show that grassland biodiversity is linked to ecosystem functioning (BEF Theory) and to its capacity to deliver a large diversity of ecosystem services (ES). However, till now no methods allow an easy diagnosis of the level of ES produced, neither a concomitant evaluation of these services (i.e. forage production, biodiversity conservation and pollination or carbon sequestration). Our goal was to develop indicators of ES using botanical surveys (as a proxy of biodiversity), because botanical survey is quite easily accessible and is integrative of the spatiotemporal variability of grassland ecosystems. We used a multicriteria analysis tools to aggregate different criteria calculated from botanical survey to assess ES scores (ranged from 0 to 1). This tool used a set of indicators, which mixed academic knowledge and expertise. The first step was to develop a set of indicators (selection of the botanical survey criteria and the way to aggregate them) based on literature survey. Then, they were discussed with 20 experts during a workshop to produce a more finalized version of the indicators. 6 ES, i.e. forage production and quality, flexibility of forage production, nitrogen availability for vegetation, biodiversity conservation, resilience hazards and pollination, were selected.

Abstract

International audience; Permanent grasslands cover one third of the total utilised agricultural area in Europe. They play a major role in livestock feeding and ecosystem service supply. European grasslands are submitted to agricultural practices with different levels of intensity defining land-use intensifica- tion. Land-use intensification impacts indirectly pollinator communities due to change in flower traits. These modifications of the plant-pollinator interactions and pollinator communities can impact pollination function in grasslands. However, little is known about the mechanisms ex- plaining the modification of pollinator communities and pollination function due to change in flower traits with land-use intensification. Furthermore, no study establishes these links with a set of quantitative flower traits giving a holistic view of flower. Hence, we will answer to the following questions: (1) what are the impacts of contrasting land-use intensification levels on functional diversity of flower traits of grasslands? (2) What are the consequences of these im- pacts on plant-pollinator interaction frequencies, which are proxies of pollination function? We selected 16 grassland plots with a contrasting level of intensification in the North East of France (Moselle). 2800 pollinators belonging mainly to three Orders (Hymenoptera, Diptera, Lepi- doptera) were captured in interaction with flowers on transects five times from May to August 2017 on each plot. Flower areas were measured on 47 grassland plant species. Using linear mixed models, our first results indicate a negative relationship between the land-use intensification and the community weighted mean of flower area. We also found a positive relationship between the flower area (community weighted mean and functional diversity) and plant-pollinator interac-tion frequencies. These results suggest an impact of land-use intensification on diversity of floral traits and change in plant-pollinator interactions. Our future measurements of other flower andpollinator traits will allow us to better understand the relationships between level of land-use intensification and pollination function in European grasslands.

Abstract

Climate reconstructions in temperate Europe have been widely based on oak species. However, other co‐occurring species, largely distributed in Europe, may be used for recording climate variability. In this paper, we documented the inter‐trees and inter‐species variations over 1960‐2007 of oxygen and carbon isotopic compositions in ring cellulose of F. sylvatica, P. sylvestris and Q. petraea co‐occurring in the Fontainebleau forest (France). Our results indicated that large levels of series replication (11 trees on average) were required to generate isotopic mean series representative of the populations. We calculated mean isotopic ratios in pine higher than in the deciduous species, and hypothesized that these contrasts resulted from differences in stomatal conductance, phenology and canopy structure, and, for oxygen, also in water uptake depth and isotopic exchange rate. We found that δ18O and δ13C chronologies were significantly correlated to one another in the three species and responded primarily to air moisture and Tmax, which indicated that stomatal conductance was an important driver of changes in both types of records. We determined that the correlations were strong with the May to July climate variables in F. sylvatica, and with the July and August ones in Q. petraea and P. sylvestris. We showed that the oxygen records were systematically more coherent than those of carbon. This study demonstrated that δ18O, and to a lesser extent δ13C, from the three different species are reliable proxies for reconstructing past hydroclimatic variations in Europe.

Abstract

International audience; Ring δ13C is a physiological and climatic archive that offers resolution at the annual and seasonal time scales. In this contribution, we synthesize our results relative to the functional understanding of the intra-ring δ13C variations. Our experimental approach consists in studying processes that are likely to influence the seasonal δ13C variations. We focus on two deciduous European species: Quercus petraea and Fagus sylvatica.One main result in oak is the identification of a recurrent pattern of the seasonal variations of the δ13C. These variations were mainly related to the mobilization of carbon reserves at the beginning of growth (high δ13C values) and to the influence of environmental conditions on the photosynthetic discrimination during the rest of the growing season. The δ13C of the latewood was correlated to climatic conditions (especially vapor pressure deficit, soil water content). For Fagus, there was no apparent reserve effect at least in healthy trees. However, in declining beech trees, δ13C values tended to be higher (Granda et al. in prep) and an intra-ring δ13C decrease reveals a difference in starch storage dynamics compared to healthy trees (Michelot et al. in prep).The δ13C intra-annual variations of the ring bulk organic matter were little influenced by variations in biochemical composition (in particular, lignin and holocellulose contents, Eglin et al. 2009). Comparisons between water use efficiency (WUE, the ratio of carbon assimilation and stomatal conductance to water) calculated from a leaf carbon isotope discrimination model applied to δ13C ring data and simulated or measured WUE at the tree or ecosystem levels suggest that latewood δ13C is a seasonal recorder of WUE with a time lag corresponding to the mixing time of sugars in the phloem (Michelot et al. 2011). Recent results at the inter-annual scale over 8 years indicate that the maximal correlation between WUE deduced from δ13C and that obtained from C and H2O flux is obtained with a time lag of 1-20 days. Moreover, intra annual δ13C patterns exhibited important inter-annual and inter-individual variability which were mainly attributed to inter-annual climate variations and competitive status of the trees respectively.These data from experiments have been used to elaborate a mechanistic model simulating the carbon isotopic balance at tree-scale (Eglin et al. 2010). This model has been coupled with CASTANEA, a model simulating the carbon, water and energy balances at stand-scale, then calibrated and validated on measurements of intra-annual variations of δ13C within oak rings, sampled in the Barbeau forest (ICOS network, http://www.barbeau.u-psud.fr/). Results from ISOCASTANEA showed a strong attenuation of the carbon isotopic signal from the leaf to the ring. Key parameters influencing the simulated whole-tree-ring δ 13C was tested by a sensitivity analysis: budburst date, growth rate and the discrimination during respiration are particularly important. From a physiological point of view, use of inter-annual intra-ring δ13C associated with other variables like anatomy, microdensity could particularly relevant to examine the importance of the functional life history of the trees to explain their vulnerability to climate change.

Abstract

Afin d’identifier et de promouvoir les mesures qui permettront de diminuer la vulnérabilité de la société face aux effets du réchauffement climatique,la France a mis en place son premier Plan National d’Adaptation au Changement Climatique(PNACC) en 2011. Concernant les écosystèmes forestiers, ce plan prévoit notamment deux mesures complémentaires : la mise en ligne d’indicateurs de changement climatique en forêt (2.3) et la valorisation et l’adaptation du monitoring forestier pour le suivi de la réponse des écosystèmes au changement climatique (2.4). En France, l’Observatoire National sur les Effets du Réchauffement Climatique (ONERC) met à disposition du public un jeu d’indicateurs sur le changement climatique et ses impacts (tous milieux confondus). Le nombre d’indicateurs a progressivement augmenté depuis 2005 pour atteindre environ 25 à ce jour. Parmi eux, un seul indicateur concerne la forêt: le front d’expansion de la chenille processionnaire du pin. Le projet SICFOR a été mené durant l’année 2013 afin d’établir un jeu d’indicateurs potentiels du changement climatique en forêt. Financé par le Ministère de l'agriculture, de l'agroalimentaire et de la forêt et coordonné par le GIP Ecofor, il s’est appuyé sur une expertise associant chercheurs, agents du développement et décideurs. Le travail a été structuré en cinq groupes thématiques autour des différents types d’indicateurs : bioclimatiques, phénologiques, productivité et santé des forêts, répartition des espèces, et adaptation de la gestion forestière. Les questions auxquelles les indicateurs potentiels devaient répondre ont été formulées, puis chaque indicateur a été évalué selon une grille construite à partir de modèles existants. Les principaux résultats du projet SICFOR sont (i) une synthèse des indicateurs du changement climatique disponibles au niveau mondial, en particulier pour les écosystèmes forestiers, (ii) une proposition d’un jeu d’indicateurs potentiels et leur évaluation, (iii) le recensement des données actuellement disponibles pour la construction de ces indicateurs, notamment via les dispositifs d’observation existants, et (iv) la présentation des recherches en cours et les limites pour mener à bien les actions sus-mentionnées du PNACC.

43. Using Matching Traits to Study the Impacts of Land-Use Intensification on Plant-Pollinator Interactions in European Grasslands: A Review.

Author

Goulnik J, Plantureux S, Dajoz I, and Michelot-Antalik A

Abstract

Permanent grasslands are suitable habitats for many plant and animal species, among which are pollinating insects that provide a wide range of ecosystem services. A global crisis in pollination ecosystem service has been highlighted in recent decades, partly the result of land-use intensification. At the grassland scale, however, the underlying mechanisms of land-use intensification that affect plant-pollinator interactions and pollination remain understudied. In this review, we first synthesise the literature to provide new insights into the relationships between land-use intensification and pollination by using matching community and interaction traits. We then identify knowledge gaps and summarise how land-use intensification of grassland influences floral traits that may in turn be associated with modifications to pollinator matching traits. Last, we summarise how these modifications may affect pollination function on permanent grasslands. Overall, land-use intensification may lead to a shift in flower colour, a decrease in mean nectar tube depth and a decrease in reward production and pollen quality at the community level. This, in turn, may generate a decrease in pollinator mouthparts length and body size, that may favour pollinators that require a low amount of floral reward. We found no study citing the effect of land-use intensification on volatile organic compounds emitted by flowers despite the importance of these molecules in pollinator community composition. Overall, our review highlighted major knowledge gaps about the effects of land-use intensification on plant-pollinator interactions, and suggests that land-use intensification could favour plants with generalised floral traits that adversely affect pollination.

Abstract

Forest decline is reported in recent decades all over the world. However, developing a clear vision of the associated tree dysfunctioning is still a challenge for plant physiologists. In this study, our aim was to examine the seasonal carbon adjustments of beech trees in the case of a long-term drought-induced decline. We compared healthy and declining trees in terms of stem radial growth, phloem sugar content and δ13C, together with xylem carbohydrates and intra-ring δ13C patterns. The radial growth of declining trees was clearly reduced by lower growth rates and shorter growing season length (44 days compared with healthy trees). The soluble sugar content was higher in the xylem of declining trees compared with the healthy ones, but similar in the phloem except at the end of their growth. Declining trees increased their levels of xylem starch content from budburst until the date of maximal growth rate. These reserve dynamics revealed an early trade-off between radial growth and starch storage that might be the result of an active or passive process. For declining trees, the slight decrease of intra-ring cellulose δ13C pattern during the early growing season was attributed to the synthesis of 13C enriched starch. For healthy trees, δ13C patterns were characterized by a progressive 13C increase along the ring, attributed to increased water-use efficiency (WUE) in response to decreased water availability. Individual variations of the crown area were negatively correlated to the intra-ring δ13C amplitude, which was ascribed to variations in canopy WUE and resource competition for healthy trees and partly to variations in the amount of reserves accumulated during spring for declining ones. Our study highlights the carbon physiological adjustment of declining trees towards reducing spring growth while storing starch, which can be reflected in the individual intra-ring cellulose δ13C patterns., (© The Author(s) 2019.
