Globalization and economic growth are widely recognized as important drivers of biological invasions. Consequently, there is an increasing need for governments to address the role international trade in their strategies prevent species introductions. However, many most problematic alien not recent arrivals but were introduced several decades ago. Hence, current patterns alien-species richness may better reflect historical rather than contemporary human activities, a phenomenon which might be...
Abstract In the context of climate change, effects prolonged or more severe droughts on pest and pathogen damage are a major concern for forest ecosystems. To date, there is great uncertainty about direction, magnitude sources variation in responses to drought by insects fungi. We report outcomes meta‐analysis 100 pairwise comparisons insect water‐stressed control trees from 40 publications. The type feeding substrate fungi water stress severity emerged as main factors influencing level...
Oaks are an important part of our natural and cultural heritage. Not only they ubiquitous in most common landscapes1 but have also supplied human societies with invaluable services, including food shelter, since prehistoric times2. With 450 species spread throughout Asia, Europe America3, oaks constitute a critical global renewable resource. The longevity (several hundred years) probably underlies their emblematic historical importance. Such long-lived sessile organisms must persist the face...
The aim of the present study was to explore possible effects climate change on geographic range or local impact several forest-pathogenic fungi. To this aim, (i) parameters species' responses climatic variables were determined, in two types models (specific statistical and generic model CLIMEX); (ii) these used make simulations under a future scenario based general circulation climate, which regionalized over France. A pathogens commonly reported Europe studied: Melampsora larici-populina,...
Abstract This study examines the effects of climate warming on one most widely distributed and destructive forest pathogens, Phytophthora cinnamomi . In Europe, winter survival pathogen is dominant cue for development disease it causes to oaks, especially Quercus robur Q. rubra The potential geographic ranges were compared in France between two reference periods, 1968–1998 2070–2099. Simulations obtained by combining a physiologically based approach predicting relation microhabitat...
Abstract • Context Powdery mildew is one of the most common diseases oaks in Europe. After alarming reports beginning twentieth century following presumed introduction invasive fungus, disease has become familiar to foresters. However, its impact may vary greatly according intrinsic and extrinsic factors. Aims We aimed at providing updated synthesised information on powdery oak effects environment disease. Methods A comprehensive literature review was performed, including old early epidemics...
Summary Little is known about the potential effect of climate warming on phyllosphere fungi, despite their important impact dynamics and diversity plant communities. The structure fungal assemblages along elevation gradients may provide information this effect, because correspond to temperature over short geographic distances. We thus investigated variations in composition inhabiting E uropean beech ( F agus sylvatica ) at four sites a gradient 1000 m rench P yrénées M ountains, by using...
Abstract Fungi are among the most diverse and ecologically important kingdoms in life. However, distributional ranges of fungi remain largely unknown as do ecological mechanisms that shape their distributions 1,2 . To provide an integrated view spatial seasonal dynamics fungi, we implemented a globally distributed standardized aerial sampling fungal spores 3 The vast majority operational taxonomic units were detected within only one climatic zone, spatiotemporal patterns species richness...
Abstract Sphaeropsis shoot blight, caused by Diplodia pinea and scrobiculata , damage conifers throughout the world. In France, first disease outbreaks were reported during 1990s. The factors associated with pathogen presence in stands relationship between distributions analysed order to understand emergence. Eighty‐two of Pinus nigra, sylvestris, pinaster radiata visited. Cones collected on ground assess frequency. spp isolated determined a species‐specific PCR test. role potential...
Summary The timing of tree flushing follows strong phenotypic and genetic clines across environmental gradients. It may be seen as an adaptive response to abiotic (escape spring frost maximizing growing season length) biotic pest disease) hazards. However, few studies have investigated jointly both types We assessed exposure (spring frost) (powdery mildew) hazards within between sessile oak populations along elevation gradients, during the period in several years. For each population...
Novel methods for sampling and characterizing biodiversity hold great promise re-evaluating patterns of life across the planet. The airborne spores with a cyclone sampler, sequencing their DNA, have been suggested as an efficient well-calibrated tool surveying fungal diversity various environments. Here we present data originating from Global Spore Sampling Project, comprising 2,768 samples collected during two years at 47 outdoor locations world. Each sample represents DNA extracted 24 m
In 1995 and 1996, a survey for the presence of Phytophthora cinnamomi in cork holm oak sites southeastern France was carried out.Twenty-four were chosen.Tree decline severity other characteristics assessed.Subplots four trees more fully investigated: relative soil water content assessed isolation attempted from samples.When cortical lesions observed, isolations out infected tissues.In six one sites, P. isolated or trunks.All different isolates obtained aggressive on oaks.However, these...
Compartmentalization and nestedness are common patterns in ecological networks. The aim of this study was to elucidate some the processes shaping these a well resolved network host/pathogen interactions.Based on long-term (1972-2005) survey forest health at regional scale (all French forests; 15 million ha), we uncovered an almost fully connected 51 tree taxa 157 parasitic fungal species. Our analyses revealed that compartmentalization maps out ancient evolutionary history seed plants, but...
Quercus robur and Q. petraea are major European forest tree species. They have been affected by powdery mildew caused Erysiphe alphitoides for more than a century. This fungus is biotrophic foliar pathogen that diverts photosynthetate from the plant its own nutrition. We used dendrochronological approach to investigate effects of different levels infection severity on radial growth young oak trees. Oak was monitored at individual level, two sites in southwestern France, over five-year period...
Historically, fungal multigene phylogenies have been reconstructed based on a small number of commonly used genes. The availability complete genomes has given rise to new wave model organisms that provide large genes potentially useful for building robust gene genealogies. Unfortunately, cross-utilization these resources study phylogenetic relationships in the vast majority non-model fungi (i.e. "orphan" species) remains an unexamined question. To address this problem, we developed method...
Abstract Forest disease management relies principally on a preventive approach in which epidemiological surveillance plays crucial role. However, efficient and cost‐effective methods are not currently available for large spatial scales. Nevertheless, aerobiological networks have been set up several decades many countries to monitor pollen dispersal provide real‐time assessments of allergenic risk. Here, we suggest that the same could be used forest pathogens. Using molecular methods,...
