Summary In this work we analyzed the degradation of floral scent volatiles from Brassica nigra by reaction with ozone along a distance gradient and consequences for pollinator attraction. For purpose used system comprising three tubes in which conducted measurements using proton‐transfer‐reaction time‐of‐flight mass spectrometer ( PTR ‐ TOF MS ) GC . We also tested effects on responses generalist Bombus terrestris The chemical analyses revealed that supplementing air led to an increasing...
Ecology Letters (2010) 13: 1172–1181 Abstract Volatile organic compounds (VOCs) emitted by damaged plants convey information to undamaged neighbouring plants, and previous research has shown that these signals are effective over short distances in nature. Many herbivore‐induced VOCs react with ozone, which is the most important tropospheric air pollutant rural areas. We used extrafloral nectar (EFN) secretion as a phenotypic indicator of between‐plant communication Phaseolus lunatus L. (Lima...
Abstract Plant-emitted volatile organic compounds (VOCs) play important roles in plant-insect interactions. Atmospheric pollutants such as ozone (O 3 ) can react with VOCs and affect the dynamics fidelity of these However, effects atmospheric degradation plant on interactions remains understudied. We used a system comprising Brassica oleracea subsp. capitata (cabbage) specialist herbivore Plutella xylostella to test whether O -triggered VOC disturbs larval host orientation investigate...
Botanical air filtration is a promising technology for reducing indoor contaminants, but the underlying mechanisms need better understanding. Here, we made set of chamber fumigation experiments up to 16 weeks duration, study efficiencies seven volatile organic compounds (VOCs; decane, toluene, 2-ethylhexanol, α-pinene, octane, benzene, and xylene) monitor microbial dynamics in simulated green wall systems. Biofiltration functioned on sub-ppm VOC levels without concentration-dependence....
Abstract. Ecosystems exchange climate-relevant trace gases with the atmosphere, including volatile organic compounds (VOCs) that are a small but highly reactive part of carbon cycle. VOCs have important ecological functions and implications for atmospheric chemistry climate. We measured ecosystem-level surface–atmosphere VOC fluxes using eddy covariance technique at shallow subarctic lake an adjacent graminoid-dominated fen in northern Sweden during two contrasting periods: peak growing...
ABSTRACT Soil microbial diversity and community structure play pivotal roles in maintaining multiple ecosystem functions biogeochemical cycling. However, the patterns mechanisms of grazing effects on bacterial fungal remain poorly understood a broad scale. To address this issue, we conducted meta‐analysis by compiling comprehensive dataset consisting 543 paired observations from 48 manipulative experiments grassland ecosystems. Pooling all data, our results indicated that significantly...
Summary 1. Many plant species have two inducible indirect defences against herbivores, emission of volatile organic compounds (VOCs) and secretion extrafloral nectar (EFN). Moreover, herbivore‐induced VOCs can serve as airborne signals in plant–plant communication, inducing and/or priming undamaged neighbouring plants. However, it remains largely unknown, particularly woody plants, whether induce prime these simultaneously. 2. We investigated the VOC‐mediated induction VOC EFN hybrid aspen (...
Epichloë endophytes are common symbionts living asymptomatically in pooid grasses and may provide chemical defences against herbivorous insects. While the mechanisms underlying these fungal have been well studied, it remains unknown whether endophyte presence affects host's own defences. We addressed this issue by examining variation impact of on constitutive herbivore-induced emissions volatile organic compounds (VOC), a well-known indirect plant defence, between two grass species,...
Abstract Background The point mutation at codon 200 ( TTC → TAC , F200Y ) of the β 2 ‐ tubulin gene confers resistance to benzimidazole fungicide in Fusarium asiaticum . These isolates with this have been detected mainly by determining minimum inhibitory concentration MIC fungicides, which is always time consuming, tedious and inefficient. Results A visual, rapid efficient method high specificity was developed, based on loop‐mediated isothermal amplification LAMP ). Six sets primers were...
Insect herbivory is known to augment emissions of biogenic volatile organic compounds (BVOCs). Yet few studies have quantified BVOC responses insect in natural populations pan-Arctic regions. Here, we assess how quantitative and qualitative change with increasing herbivore feeding intensity the Subarctic mountain birch (Betula pubescens var pumila (L.)) forest. We conducted three field experiments which manipulated larval density geometrid moths (Operophtera brumata Epirrita autumnata), on...
Dark septate endophytes (DSEs), one of the most common fungal colonizers roots, are considered to overlap in function with mycorrhizal fungi. However, there is little knowledge on distribution and identity DSEs 'non-mycorrhizal' plants. In current study, colonization diversity colonizing roots eight typically families were assessed. total, 120 root samples 31 plant species all colonized by DSEs. Intensity DSE varied greatly among different species, a range 0.56–47.56%, 8.13% average....
Abstract Some insectivorous birds orient towards insect‐defoliated trees even when they do not see the foliar damage or herbivores. There are, however, only a few studies that have examined mechanisms behind this foraging behaviour. Previous suggest can use olfactory cues (e.g. volatile organic compounds ( VOC s) emitted by defoliated plants), indirect visual combination of two sensory cues. s from plants are known to attract natural enemies herbivores, and researchers hypothesized could...
Abstract Traditionally, biogenic volatile organic compound (BVOC) emissions are often considered a unidirectional flux, from the ecosystem to atmosphere, but recent studies clearly show potential for bidirectional exchange. Here we aimed investigate how warming and leaf litter addition affect exchange (flux) of BVOCs in long‐term field experiment Subarctic. We also assessed changes net BVOC fluxes relation time day influence different plant phenological stages. The study was conducted full...
Abstract Climate change increases the insect abundance, especially in Arctic ecosystems. Insect herbivory also significantly plant emissions of volatile organic compounds (VOCs), which are highly reactive atmosphere and play a crucial role atmospheric chemistry physics. However, it is unclear how effects on VOC interact with climatic changes, such as warming increased cloudiness. We assessed experimental manipulations temperature light availability subarctic tundra, that had been maintained...
The mountain birch [Betula pubescens var. pumila (L.)] forest in the Subarctic is periodically exposed to insect outbreaks, which are expected intensify due climate change. To mitigate abiotic and biotic stresses, plants have evolved chemical defenses, including volatile organic compounds (VOCs) non-volatile specialized (NVSCs). Constitutive induced production of these compounds, however, poorly studied populations birch. Here, we assessed joint effects herbivory, elevation season on foliar...
In arctic and subarctic regions, rapid climate changes enhance biogenic volatile organic compound (BVOC) emissions from vegetation, with potentially significant influence on atmospheric processes. However, the seasonal diel patterns of bidirectional exchange (flux) BVOCs remain poorly studied in these regions. Here, we deployed a proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF-MS) to investigate ecosystem-level BVOC fluxes over growing season tundra heath Abisko, Northern...
