Summary An analysis of incidence Phytophthora spp. in 732 European nurseries producing forest transplants, larger specimen trees, landscape plants and ornamentals, plus 2525 areas which trees shrubs were planted, is presented based on work conducted by 38 research groups 23 countries between 1972 2013. Forty‐nine taxa recorded 670 (91.5%); within these nurseries, 1614 1992 nursery stands (81.0%) infested, although most affected appeared healthy. In plantings, 56 recovered from 1667 tested...
Abstract Non-native pests, climate change, and their interactions are likely to alter relationships between trees tree-associated organisms with consequences for forest health. To understand predict such changes, factors structuring communities need be determined. Here, we analysed the data consisting of records insects fungi collected from dormant twigs 155 tree species at 51 botanical gardens or arboreta in 32 countries. Generalized dissimilarity models revealed similar relative importance...
The number of invasive alien pest and pathogen species affecting ecosystem functioning, human health economies has increased dramatically over the last decades. Discoveries pests pathogens previously unknown to science or with host associations yet damaging on novel hosts highlights necessity developing tools predict their appearance in hitherto naïve environments. use sentinel plant systems is a promising tool improve detection before introduction provide valuable information for...
Multispectral imagery from unmanned aerial vehicles (UAVs) can provide high-resolution data to map tree mortality caused by pests or diseases. Although many studies have investigated UAV-imagery-based methods detect trees under acute stress followed mortality, few tested the feasibility and accuracy of detecting chronic stress. This study aims develop test how well UAV-based multispectral pine needle disease long before mortality. images were acquired four times through growing season in an...
European ash (Fraxinus excelsior) is threatened by the invasive ascomycete Hymenoscyphus fraxineus originating from Asia. Ash leaf tissues serve as a route for shoot infection but also sporulation substrate this pathogen. Knowledge of niche partitioning indigenous fungi and H. needed to understand fungal community receptiveness invasion. We subjected DNA extracted unwashed washed leaflets healthy diseased PacBio sequencing ITS1-5.8S-ITS2 rDNA region. Leaflets co-inhabiting rowan trees...
During extensive surveys of global
Abstract International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi insects) to spread into new areas. To mitigate these risks, a large-scale assessment tree-associated insects is needed. We present records endophytic twigs 17 angiosperm gymnosperm genera, from 51 locations 32 countries worldwide. Endophytic were characterized by high-throughput sequencing 352 samples 145 species 28 countries. Insects reared 227 109 18 sorted...
Summary Dothistroma needle blight (DNB) is among the most serious foliar diseases affecting Pinus spp. globally. Infected needles were collected from potential host species in four locations western Ukraine and eastern Georgia during spring–summer 2015 to update knowledge on pathogen distribution these countries. detected using isolation, sequencing species‐specific priming (SSPP) PCR. Two new hosts for recorded Ukraine: D. septosporum nigra var. australica pini P. mollet . was found...
Abstract In western Ukraine, forest decline and dieback of several broadleaved tree species have become increasingly evident during recent years, surveys in some areas shown symptoms indicative Phytophthora infections. this study, we aimed to determine the occurrence diversity associated with ( Alnus glutinosa , Betula pendula Castanea sativa, Fagus sylvatica Quercus robur ) from stands where has been observed. Rhizosphere soil samples were collected 14 2017 2018 tested for presence using...
Summary Ten saplings of European ash ( F raxinus excelsior L.) naturally infected by the invasive dieback pathogen Hymenoscyphus fraxineus were collected in Ukraine and Norway examined for bark necrosis extension discoloration sapwood pith a stem region. Tissue‐specific colonization profiles determined spatial analyses symptomatic visually healthy tissues using H. fraxineus‐ specific qPCR assay light microscopy. Our data suggest that hyphal growth starch‐rich perimedullary is particular...
За останні десятиліття на території Українських Карпат відбувається масове всихання похідних ялинових насаджень, створених у висотних поясах дубових та ялицево-букових лісів. Встановлено, що причини лісів мають комплексний характер і є наслідком взаємодії трьох компонентів складної системи (тріади) конкретних умовах той самий час:1) чинники зовнішнього середовища (абіотичні, антропогенні), які погіршують стан дерев посилюють дію патогену (або групи патогенів) сприяють масовому розвитку...
Abstract Lecanosticta acicola is a pine needle pathogen causing brown spot blight that results in premature shedding with considerable damage described North America, Europe, and Asia. Microsatellite mating type markers were used to study the population genetics, migration history, reproduction mode of pathogen, based on collection 650 isolates from 27 countries 26 hosts across range L. . The presence Georgia was confirmed this study. Migration analyses indicate there have been several...
Abstract In declining broadleaf forests in western Ukraine, several Phytophthora species including P. plurivora , bilorbang polonica gonapodyides and cactorum were recovered using soil baiting assays identified morphological molecular methods. Pathogenicity tests of selected isolates performed on black alder ( Alnus glutinosa (L.) Gaerth.) silver birch Betula pendula Roth.) to assess susceptibility these two tree the newly detected species. showed higher pathogenicity both compared other tested
Summary Occurrence of Phytophthora species in the rivers Stryj and Yasenytsya lake situated National Park „Skoliwski Beskidy” Ukraina was studied. Detection pathogen carried out October November 2011. Baiting technique with rhododendron leaf baits cultivar Nova Zembla used for microorganisms isolation from water. Species were identified on basis their morphological features using molecular methods. Studies showed occurrence gonapodyides, P. lacustris Pythium litorale analyzed water sources....
Інвазійні види комах є важливим чинником, який суттєво впливає на стан дерев у лісах і насадженнях населених пунктів. Встановлено видовий склад найбільш небезпечних видів інвазійних комах-філофагів (фоліофагів), які проникли територію України. Охарактеризовано біологічні особливості філофагів із груп: комахи гризним ротовим апаратом, мінуючі, колюче-сисним галоутворюючі комахи. Виявлено небезпечні та охарактеризовано їхній вплив лісів зелених насаджень Серед комах-інвайдерів види, успішно...
