Abstract There is tremendous diversity of interactions between plants and other species. These relationships range from antagonism to mutualism. Interactions with members their ecological community can lead a profound metabolic reconfiguration the plants’ physiology. This favour beneficial organisms deter antagonists like pathogens or herbivores. Determining cellular molecular dialogue plants, microbes, insects, its evolutionary implications important for understanding options each partner...
Global change challenges the adaptive potential of forests. Large-scale alterations forest canopies have been reported across Europe, and further modifications are expected in response to predicted changes drought windstorm regimes. Since dynamic interfaces between atmosphere land surface, communities canopy-dwelling insects at forefront major both direct indirect effects climate change. First, we briefly introduce factors shaping arthropod canopy temperate Second, cover significant impacts...
Abstract The genus Agrilus is one of the most diverse insect genera worldwide. larval feeding activity causes extensive damage in both forests and orchards. In addition, more than 30 species have been introduced outside their native range so far, including emerald ash borer planipennis Fairmaire. Thus, availability efficient trapping protocols for early detection at entry points utmost importance. this study we tested whether developed surveillance A. North America were also effective other...
Abstract Aim Climate is a major driver of large‐scale variability in biodiversity, as likely result more intense biotic interactions under warmer conditions. This idea fuelled decades research on plant‐herbivore interactions, but much less known about higher‐level trophic interactions. We addressed this gap by characterizing both bird diversity and avian predation along climatic gradient at the European scale. Location Europe. Taxon Insectivorous birds pedunculate oaks. Methods deployed...
The phylogeography of the bark beetle Ips typographus was assessed using five microsatellite markers. Twenty-eight populations were sampled throughout Europe on host tree Picea abies. I. showed very low levels genetic diversity, and study revealed a lack structure across Europe. No significant barrier to gene flow found, even though P. abies has fragmented distribution. A weak but effect isolation by distance found. These results suggest high dispersal capacity typographus, which leads...
Abstract Aim The strength of species interactions is traditionally expected to increase toward the Equator. However, recent studies have reported opposite or inconsistent latitudinal trends in bottom‐up (plant quality) and top‐down (natural enemies) forces driving herbivory. In addition, these rarely been studied together thus limiting previous attempts understand effect large‐scale climatic gradients on Location Europe. Time period 2018–2019. Major taxa Quercus robur . Methods We...
The SoilTemp database will identify the microhabitats that best buffer amplitude of warming. temperature heterogeneity at spatial scales below meter also requires attention.

The genus Agrilus includes two species, A. planipennis and anxius , that are of particular phytosanitary concern regulated by the European Union legislation. This implies agencies all EU countries obliged to establish specific surveillance programmes verify absence these species from their territory. These activities commonly consist use green-colored traps, which however attractive not only for but also a wide range other species. For this reason, much time expertise is required sort...
Abstract An increase in biotic interactions towards lower latitudes is one of the most consistent patterns ecology. Higher temperatures and more stable climatic conditions at low are thought to enhance interactions, accelerating biological evolution leading stronger anti-herbivore defences plants. However, some studies report contradictory findings, highlighting need for further investigation into underlying mechanisms. We used a combination field observations feeding trials controlled...
This study was aimed at determining the composition of Ips typographus L. (Coleoptera: Scolytidae) associated fungal flora in France, its virulence, and ability to stimulate host defence reactions. The relationship between these parameters beetle population levels also considered. conducted 2001, 2002, 2003 Norway spruce (Picea abies (L.) Karst.) stands, with different bark damage levels. In each stand, frequency association fungi I. determined. virulence most frequent species assessed...
Abstract Global warming is predicted to enhance the development rate and increase number of generations in multivoltine insects. For secondary forest pests, such as pine bark beetle I ps sexdentatus , resulting population level could trigger more frequent outbreaks. However, this positive effect be outweighed by a temperature‐dependent decrease offspring quality. To test these hypotheses, we carried out laboratory rearing experiment with maritime logs at six temperature regimes reproducing...
Buprestids are an emerging threat to broadleaf forests across the world. Species such as emerald ash borer (EAB, Agrilus planipennis) seriously threaten (Fraxinus spp.) in North America and Europe. As it continues spreading west from European Russia, native populations will suffer dramatic losses. Due their cryptic lifestyle of egg larval stages on developing bark vascular tissue, buprestids other wood borers can be difficult detect. Early detection tools vital implement fast eradication...
Abstract Pityogenes chalcographus L. (Coleoptera: Scolytinae) causes damage in European coniferous forests, primarily on Picea abies Karst., but is also recorded other native and exotic Pinaceae species. Estimating the adequacy between adult preference larval performance of this beetle among its host‐range, as well influence plant taxonomic relatedness these parameters, would provide useful information beetle's ability to shift onto novel hosts. Choice no‐choice assays were conducted under...
Abstract 1. Variations in developmental conditions of bark beetles, particularly intraspecific competition, can induce morphological and physiological modifications the offspring. It is hypothesised that competition could also affect host selection behaviour. Such behavioural changes might be manifested response to (alpha‐pinene) or beetle (verbenone) compounds. 2. Ips pini were bred at different densities. The offspring measured for size, weight, lipid concentration, then subjected...
We examined the influence of seasonal water stress on resistance Pinus yunnanensis (Franch.) to inoculation with Leptographium yunnanense, a pathogenic fungus associated aggressive bark beetle, Tomicus n. sp. Experiments took place between October 1997 and November 1999 in two plots located at top foot hill Shaogiu, China, region characterized by dry winters wet summers. Following isolated mass fungal inoculations, we observed reaction zone length, growth phloem, occlusion, blue-staining...
