Title: City longhorn beetle (Aeolesthes sarta): A review of the species, its distribution, ecology, damage, prevention and control
Abstract: The city longhorn beetle (Aeolesthes sarta) (CLB) (Coleoptera - Cerambycidae) is a polyphagous invasive pest of both healthy and suppressed broadleaved trees in central Asia. CLB causes a great degree of damage in the countries of its origin. To understand this pest in a better way, a detailed review study has been conducted to gather all the valuable information related to the CLB. This review study covers the main aspects of the CLB, its morphology, ecology, distribution, damage, and control measures. The life span of the CLB is two years. It is mainly distributed in the central Asian countries and preferably damages broadleaved tree species, especially Juglans regia, Populus alba, P. euphratica, Acer spp, Salix alba, S. babylonica, Malus pumila, M. sylvestris, Platanus orientalis and Ulmus spp. Effective control and management practices include cutting, removing + burning of infested trees, cultivating high resilient tree species, use of biocontrol agents (i.e. fungus), and use of aluminium phosphide as a pesticide to significantly help control the CLB population. A CLB invasion in a new favourable habitat could impose a serious threat to broadleaf forests and plantations. Therefore, the keen monitoring and surveying of woodland management techniques are recommended. The strict monitoring and inspection of traded wood material at airports and seaports are highly recommended. There is a need to conduct multiple research studies to profoundly understand the CLB phenology, ecology, transportation mode, and damage severity to bridge the gap.

Title: Analyses of periodic annual increment by diameter and volume in differently aged black locust (Robinia pseudoacacia L.) stands: Case study
Abstract: Black locust is one of the most commonly planted exotic tree species in the world. It has a crucial role in mitigating the negative effects of climate change. Its increment analyses have a key role in forest planning. Increment is added to the wood stock of the forest over and over again, and only this continuous replenishment makes the sustainable forest management possible. This study presents the results of the analysis of periodic annual increment (PAI) by diameter (dbh) and volume (v) of two differently aged black locust (Robinia pseudoacacia L.) stands, growing under similar ecological conditions. The main correlations are as follows: PAIdbh and diameter at breast height: r = 0.601 and 0.704 (P = 0.01); PAIv and mean tree volume (v): r = 0.721 and 0.849 (P = 0.01). The presented correlations clearly demonstrate the importance of individual differentiation within a stand.

Title: Understanding psychological factors influencing ecosystem conservation behaviours of forest professionals
Abstract: This study was embarked upon to assess forest guards' Knowledge, Attitude and Practice (KAP) behavioural change sequences in Nigeria lowland forest reserves using a structural equation modelling approach. Two research questions were raised and corresponding hypotheses were tested. From the data analysed, it was revealed that both knowledge and attitude variables significantly predicted the behaviour of the forest guards' towards the management of the forest and its resources. Although the attitude variable on its own did not significantly predict the forest guards' behaviours (t = 1.401, P > 0.05), it can be stated that the knowledge of the forest guards towards the forest is a better predictor to their environmental behaviours and their behavioural change sequence (AKP) is inclined towards developing affinity to the forest. Hence seminar and symposiums should be organized for all forest guards with the objectives of having better efforts and persistence, preparation for action, better visualization of success, reduce stressors, and fewer intrusive negative thoughts in managing the forest and its resources. This will help boost their affinity to the forest and self-efficacy as the study revealed that the Attitude-Knowledge-Practice (AKP) sequence explains better the behaviour of the forest guards in protecting the forest reserves.

Title: Spatial relationships of trees in middle taiga post-pyrogenic pine forest stands in the European North-East of Russia
Abstract: Information on the structural organization of forest stands obtained on sample plots is the basis for long-term monitoring of post-fire pine forest structure and dynamics in the European North-East. These data can be used as a marker of native pine stands of the European taiga. Here, we studied vertical and horizontal structure in the post-pyrogenic pine forests of Vacciniosum, Vaccinioso-cladinosum and Myrtillosum site types in the boreal forest of the Komi Republic. The type of horizontal structure of uneven-aged forest stands changed with age from grouped to random one. Large trees were randomly distributed on the plot. We observed the weak aggregation of undergrowth trees (natural tree regeneration) in stands at distances of 2-6 m. Undergrowth individuals were characterized by group distribution at smaller distances than 1-2 m. Spatial relationships between large, small and codominant trees demonstrated random distribution in most cases. Undergrowth individuals did not show any competitive relations. However, we revealed a "taking off" effect between mature trees of pine and pine undergrowth. The direction of the displacement of tree crown centre projections relative to the bases of their trunks was ambiguous. The shift of the crown space towards the maximum solar radiation was detected in a thinned stand with old age and big size of trees. In other site types, no one-sided orientation of the tree crown development emerged.
