Аннотация: During 1993-1996, in central Siberia, a silkmoth (Dendrolimus superans sibiricus Tschetw.) infestation damaged approximately 700 000 ha of fir, Siberian pine and spruce stands. Temporal (1995-1997) Advanced Very High Resolution Radiometer (AVHRR) images were used for pest outbreak monitoring of this event. Damaged stands were detected, with heavy (50-75% dead and dying trees) plus very heavy (75%) levels of damage classified. Summer and winter images were used for delineation of the northern border of the region of pest outbreaks. The Siberian taiga insects were classified with respect to their harmfulness to forests, based on the frequency Of Outbreaks, the size of the damaged territory, and the available food sources based on forest type.

Аннотация: Species of Leptographium are well-known inhabitants of conifers in the Northern Hemisphere, in which they cause a blue-stain. They are also known to be associated with insects, especially bark beetles (Coleoptera: Scolytidae). Surveys of dying stands of Siberian fir (Abies sibirica) have resulted in the consistent isolation of an unknown Leptographium from the galleries of the fir sawyer beetle, Monochamus urussovi (Coleoptera: Cerambycidae). This fungus is responsible for the blue-stain in living trees. Comparison with known species of Leptographium led to the conclusion that it had not been previously described, and the name Leptographium sibiricum sp. nov, is introduced here.

Аннотация: The emerald ash borer, Agrilus planipennis, is a beetle native to East Asia where it is considered a minor pest, preferentially attacking weakened or dying ash trees. It was first discovered in North America in 2002 and has since become one of the most serious invasive insect pests, killing millions of healthy ash trees in urban and forested settings. Similar damage is now occurring in the region of Moscow, Russia, which causes serious concern for Europe. In this paper, we review the current knowledge on A. planipennis in Asia and North America, provide new information on its occurrence in the region of Moscow and Eastern Russia and make recommendations for research and management strategies in Europe.

Аннотация: A large-scale outbreak of the Siberian moth (Dendrolimus sibiricus) in the forests of the Lower Angara valley region (1993-1996) was analyzed on the basis of NOAA/AVHRR imaagery. The applicability of this type of imagery for detecting the foci of damage of tree stands with the discrimination of strong (50-75%) and very strong (>75%) dying and dead trees is demonstrated. The applicability of data from a winter survey was determined by the discovery of damaged tree stands. Summer/winter images were used in demarcating the northern boundary of the focal propagation of the Siberian moth.

Аннотация: Biotrophic fungus Melampsorella caryophyllacearum (Pucciniastraceae, Pucciniomycetes, Basidiomycota) developing in tissues of a fir (Abies sibirica) causes broom rust. Physiological mechanisms of plant resistance and fungus pathogenicity are not clear. The purpose of this work was an assessment of a role of secondary compounds and carbohydrates in mechanisms of interaction of Siberian fir and fungus M. caryophyllacearum. The 20-year age trees of Siberian fir grow in a mountain taiga zone in suburban forests of Krasnoyarsk (Central Siberia). Two options (one-year axes and needles of the current year without signs of damage by the fungus, and infected ones) were compared. Samples were taken on 3 trees 3 times during vegetation season: on June 21 (a phenology stage of shoot growth and a formation of pathogen etion), on July 19 (a phenology stage of summer vegetation and the period of active sporulation) and on September 10 (a phenology stage of autumn coloration of leaves and dying off the infected needles). The lignin and resin content were determined by weight method (the lignin determined with thioglycolic acid, the resins - by dissolving in pentane), carbohydrates - by the method of copper reduction using glucose as a standard, PAs - by coloring of solution after adding n-butanol / HCl mixture and heating. Starch was determined by coloring with iodine. The analysis of ANOVA proved reliable influence of various factors (phenology stage, plant organ (needles, axis), presence/absence of fungus infestation) on the content of PAs, lignin, monosaccharides (p < 0.05). The content of resin depended on plant organ only (resin content was more in axes, than in needles; p < 0.05). The tendency to starch accumulation in the infected axes during vegetation appeared to be caused by breakage of carbohydrates outflow. Infecting by the fungus caused decrease in the content of monosaccharides (p<0.05) that probably was connected with active consumption of mobile carbohydrates by the biotroph. The accumulation of PAs was revealed in needles and axes induced by M. caryophyllacearum fungus. Unlike PAs, the lignin concentration differently changed in the infected plant tissues. The accumulation of lignin was noted in diseased needles. In the infected axes in July the lignin content was significantly lower in comparison with control (p < 0.05). The found effect appeared to be manifestation of successful inhibition of plant protection by fungus. We suggested a hypothesis of the delayed lignification according to which a fungus inhibits synthesis of lignin and increases the chances in overcoming of protective barriers of a host. Perhaps, the pathogen influences carbon distribution by reducing its part for synthesis of lignin and increasing thereby synthesis of carbohydrates which further actively uses. The obtained data is agreed with concept according to which with effector molecules, biotrophs manipulate the defense machinery of the host in order to delay defense responses to gain enough time to multiply and spread into neighboring cells. © 2017 Russian Academy of Sciences.

Аннотация: The crown of the Siberian fir (Abies sibirica) is characterized by a specific organization, namely, a narrow-pyramidal form, apical dominance, tiering by types of sexualization, and whorled branching. The gravitational vector is clearly manifested at all levels of the organization of the crown, that is, in the architecture (diageotropism of branches), morphostructure (dorsoventrality of tissues and organs of shoots, as well as the location of reproductive organs in the tree crown and on the shoot), and physiological processes. It was shown that the internal state of the tree is a determining factor in graviperception. When Siberian fir trees weaken, the diageotropism of branches is lost, which can serve as a universal biomarker of impairment of homeostasis. © 2020, Pleiades Publishing, Inc.

Аннотация: Due to relatively long development and long life of forest-forming species most of the conclusions on stand dynamics are based on the data collected by indirect methods of comparative research and analysis of cenosis forming theoretically temporal and spatial succession sequences and need to be verified and clarified. The most reliable results on the stand dynamics can be received on stationary objects such as permanent sample areas. The article presents the analysis results of long-term monitoring (1968-2012) of a pine (Pinus sylvestris L.) stand in low-mountain Eastern Sayan on the south slope with a steepness of 7-8 degrees. The intermittent test of morphometric indicators of trees mapped on the permanent sample area was used. It is shown that the sum of tree trunk cross-section areas at breast height (1.3 m) varied by no more than 10 % with timber reserves on the lower, central and upper equal sites of the sample area during the entire observation period. At the same time heterogeneity of ecological conditions, taking place even on a small section of a smooth slope, influences the plantation self-thinning intensity. In the 42-year-old stand density ratio at lower, central and upper sites was 1:1.5:2.1. Stand density difference along the slope had been decreasing gradually over time, although it remained around 30 % at the time of the last observation. Over the years of observation, 53, 47, and 32 % of pines on the lower, central, and upper sites, respectively, have survived. The calculated average age of the died trees showed that in all groups of natural diameter classes, there was an earlier die-off of pines at the bottom of the slope with an increase in dying age up to the slope. Trees with larger trunk diameter (first telling) died later. All this led to a rearrangement of the horizontal structure of the plantation, a decrease in the average diameter and average volume of trees up to the slope. Typical for mountain forests clinal tree distribution, which affects their morphological indicators, is important to consider when studying and modeling forest ecosystems, as well as when implementing forest management measures.
