Salvage and sanitation loggings (hereafter salvage logging) are usually practiced following such disturbance events and the generated deadwood is then extracted from the forest. Those practices affect a broad array of species, including fungi, lichens, invertebrates, and vertebrates that make use of deadwood either as habitat, food resource, foraging substrate, or as shelter. Woodpeckers, being a key group of forest birds dependent on deadwood, can be affected by salvage logging in two ways: (1) a reduction in the availability of food (i.e. removal of deadwood along with the saproxylic and predatory invertebrates that usually colonize dead or dying trees following forest disturbances) and (2) a decrease in potential nest sites due to the removal of dead trees. Therefore, we assessed the global effects of salvage logging on woodpecker abundance and reproduction by conducting a meta-analysis of published and unpublished data. We focused on comparing woodpeckers’ responses to forest disturbance in salvage-logged and unlogged sites. We considered different types of responses found in the literature, including abundance, occurrence, nest density, and breeding success. When analyzing the responses of woodpeckers, we also accounted for the potential effects of tree density, time since logging, elevation, latitude, and the continent. Recent Findings We found that both numbers and reproduction of woodpeckers were affected by salvage logging following a disturbance event. Apart from salvage logging, woodpecker responses were not significantly related to any other variables. This highlights that salvage logging can pose a substantial threat to woodpecker assemblages as well as secondary cavity-users dependent on them. Summary Salvage logging and related practices that affect deadwood availability should be carefully planned and preferably avoided entirely in areas important for woodpecker conservation. In managed forests, deadwood should be retained in sufficient quantities to avoid detrimental impacts on woodpeckers and on forest biodiversity in general.}, keywords = {}, pubstate = {published}, tppubtype = {article} } Purpose of Review Wildfires, wind storms, and pest outbreaks are the main large-scale disturbances of temperate and boreal forests, which often generate large amounts of deadwood in the landscape.

Prey groups Scarabeidae beetles and other beetles (Coleoptera other) were more abundant and frequent at Mollas than at Jorgucat, and spiders were more frequent at Jorgucat. These results suggest that the high abundance of orthopterans and beetles in the food supply in certain localities is the main reason for selection and stable occupancy of these massive communal roosting sites by lesser kestrels in Albania. |

Its wide host and environmental ranges have led to its global success as a pathogen and severe economic damage to pine forests in many regions. This comprehensive global population study elucidated the historical migration pathways of the pathogen to reveal the Eurasian origin of the fungus. When over 3800 isolates were examined, three major population clusters were revealed: North America, Western Europe, and Eastern Europe, with distinct subclusters in the highly diverse Eastern European cluster. Modeling of historical scenarios using approximate Bayesian computation revealed the North American cluster was derived from an ancestral population in Eurasia. The Northeastern European subcluster was shown to be ancestral to all other European clusters and subclusters.

Its wide host and environmental ranges have led to its global success as a pathogen and severe economic damage to pine forests in many regions. This comprehensive global population study elucidated the historical migration pathways of the pathogen to reveal the Eurasian origin of the fungus. When over 3800 isolates were examined, three major population clusters were revealed: North America, Western Europe, and Eastern Europe, with distinct subclusters in the highly diverse Eastern European cluster. Modeling of historical scenarios using approximate Bayesian computation revealed the North American cluster was derived from an ancestral population in Eurasia. The Northeastern European subcluster was shown to be ancestral to all other European clusters and subclusters. The Turkish subcluster diverged first, followed by the Central European subcluster, then the Western European cluster, which has subsequently spread to much of the Southern Hemisphere. All clusters and subclusters contained both mating-types of the fungus, indicating the potential for sexual reproduction, although asexual reproduction remained the primary mode of reproduction.

Materials and Methods: To answer this question, we investigated the infestation rates and determined tree death categories (uprooted, broken, and stump) in wind-damaged areas in Western Tatra Mts. in Carpathians (Slovakia) from 2014–2016, following a windthrow in May 2014. In total, we investigated 225 trees over eight transects. For every tree, we measured its morphological (tree height, crown characteristics), environmental (solar radiation, terrain conditions, trunk zenith), temporal (time since wind damage), and beetle infestation (presence, location of attack, bark desiccation) parameters. We applied Generalized Additive Mixed Models (GAMM) to unravel the main drivers of I. typographus infestations. Results: Over the first year, beetles preferred to attack broken trees and sun-exposed trunk sides over uprooted trees; the infestation on shaded sides started in the second year along with the infestation of uprooted trees with lower desiccation rates. We found that time since wind damage, stem length, and incident solar radiation increased the probability of beetle infestation, although both solar radiation and trunk zenith exhibited nonlinear variability. Our novel variable trunk zenith appeared to be an important predictor of bark beetle infestation probability. We conclude that trunk zenith as a simple measure defining the position of downed trees over the terrain can anticipate beetle infestation.

It causes significant defoliation of affected trees; intensive attacks lead to damages of the whole stand. The relationship of trends in disease severity and intensity with climatic variables were studied in three Austrian pine plantations (Jahodná, Kálnica, Litava) during 2014–2018. During the monitoring period, the greatest variability in disease severity was observed in the top third of the crowns, which showed the highest correlation with the variants of the most important climatic conditions (temperature and relative humidity) tested. For the spread of DNB, based on statistical assessment, a higher number of intervals of environmentally favourable climatic conditions is crucial. Both Dothistroma species (D. septosporum and D. pini), which are causal agents of the disease, were identified in Jahodná. In Kálnica and Litava, only D. septosporum was present. |

The highest values of abundance and species richness were noted in summer 2016 and autumn 2017 and 2018. The highest values of mycorrhizal percentage were recorded in 21-year-old forest stands (41.95%), and the lowest values were recorded in 51-year-old stands (35.86%). Shannon index values (H´) indicate a slightly lower species diversity of ECM fungi in young stands (1.65) compared with older stands (1.71). The values of species richness and fruiting bodies abundance were statistically strongly significant (p < 0.001) during seasonality (month) and through the interaction (month/year). Amanita muscaria, Chalciporus piperatus, Russula aeruginea, and Suillus grevillei were found as indication species in the youngest stands. Amanita rubescens, Imleria badia, Inocybe lacera, and Tricholoma equestre were found as indication species in the oldest stands. |

We considered (1) the current and historical pathogen records, both positive and negative, based on confirmed reports from Europe and globally; (2) the genetic diversity and population structure of the pathogen; (3) the current distribution of PPC in Europe, comparing published models of predicted disease distribution; and (4) host susceptibility by reviewing literature and generating a comprehensive list of known hosts for the fungus. These data were collated from 41 countries and used to compile a specially constructed geo-database (http://bit.do/phytoportal). A review of 6297 observation records showed that F. circinatum and the symptoms it causes on conifers occurred in 14 countries, including four in Europe, and is absent in 28 countries. Field observations and experimental data from 138 host species revealed 106 susceptible host species including 85 Pinus species, 6 non-pine tree species and 15 grass and herb species. Our data confirm that susceptibility to F. circinatum varies between different host species, tree ages and environmental characteristics. Knowledge on the geographic distribution, host range and the relative susceptibility of different hosts is essential for disease management, mitigation and containment strategies.

We investigated how tree trunk and lower branch thickness affects the occurrence of females on trunks and branches and how the density of females and tree trunk thickness affects the occurrence of males on trunks. The research was carried out in a xeric thermophilous oak forest in southern Slovakia (Central Europe) in the winter season 2014–2015. The moths were obtained from Quercus pubescens trees by sticky bands. Three autumn species Operophtera brumata, Erannis defoliaria, Alsophila aceraria and four spring species Agriopis leucophaearia, Agriopis marginaria, Apocheima hispidaria, Phigalia pilosaria were recorded. We have found out that females had not exclusively negative geotactic behaviour as they (except for the rare P. pilosaria) occurred also on lower branches.

We investigated how tree trunk and lower branch thickness affects the occurrence of females on trunks and branches and how the density of females and tree trunk thickness affects the occurrence of males on trunks. The research was carried out in a xeric thermophilous oak forest in southern Slovakia (Central Europe) in the winter season 2014–2015. The moths were obtained from Quercus pubescens trees by sticky bands. Three autumn species Operophtera brumata, Erannis defoliaria, Alsophila aceraria and four spring species Agriopis leucophaearia, Agriopis marginaria, Apocheima hispidaria, Phigalia pilosaria were recorded. We have found out that females had not exclusively negative geotactic behaviour as they (except for the rare P. pilosaria) occurred also on lower branches.

Background and Objectives: In the context of climate and environmental changes, the following question of high importance in scientific studies is: How will Norway spruce, which forms a dominant component in European mountain and boreal forests, be able to cope with the increasing frequencies and intensities of drought periods? The aim of the study was to investigate the physiological responses of eight-month-old seedlings, as a most vulnerable phase of forest tree life, for different spruce provenances, to find out variable strategies in relation to controlled drought stress. Materials and Methods: We performed an experiment under controlled conditions with spruce seedlings from a climatologically warmer stand of 410 m above sea level (a.s.l.), and a moderately cool stand of 931 m a.s.l. The soil water content, leaf predawn water potential, the osmotic potential of needles, the relative water content of needles, and the photosynthetic performance and the contents of primary metabolites (proline and abscisic acid) were investigated as indicators of the spruce seedlings’ responses to water stress. The status of the indicators was analyzed at different temporal intervals, using repeated measures analysis of variance (ANOVA), reflecting the seedlings’ water conditions (early drought, drought, or recovery). On a daily basis, the differences among the indicators were tested with one-way ANOVA. A principal component analysis (PCA) was used to identify the provenance-specific responses of tree drought indicators in a multi-dimensional data set. Results: The responses to drought stress differed between the provenances. Whereas seedlings of ‘warm’ provenance from a low altitude performed a conservation strategy, with high amounts of accumulated abscisic acid and closing the stomata faster, the reactions of ‘cool’ provenance seedlings from a higher altitude were not so sensitive and the plants’ water supply and photosynthetic performance remained significantly higher. These findings indicate that a higher drought resistance in ‘cool’ provenance could be related to greater amounts of proline amino-acids, which are accumulated from the beginning of the drought simulation. Furthermore, proline accumulation resulting in increased stress tolerance is controlled through another mechanism than osmotic adjustment. Conclusions: The observed variations in the regulatory mechanisms used to develop adaptive strategies in different provenances are an important factor for seedling survival under a changing climate.}, keywords = {}, pubstate = {published}, tppubtype = {article} } Research Highlights: In this study, we found different regulatory mechanisms in two contrasting provenances of Norway spruce responding to progressive drought stress.

Differences in necroses lengths were significant between clones and between two ash species. Longer necroses were formed in F. angustifolia than in F. excelsior. Some clones exhibiting some resistance to the pathogen were identified. |
