We investigated the presence of spatial genetic groups within forest tree populations and determined if the genetic divergence among these groups is greater than that between populations using Scots pine (Pinus sylvestris) as a model species. We genotyped 890 adult trees of Scots pine in six natural populations in Lithuania at 11 nuclear microsatellite loci. We used a Bayesian clustering approach to identify the within-population genetic groups within each of the six populations.

Article Synopsis
  • - The study emphasizes the importance of high-resolution annual forest growth maps, using tree-ring width (TRW) data, to better understand forest carbon sequestration and the impact of climate change and drought on forest ecosystems.
  • - By integrating high-resolution Earth observation data with climate and topography information, the researchers found that species-specific models could explain over 52% of variance in tree growth, enhancing the accuracy of growth predictions compared to using just climate and elevation data.
  • - The research successfully generated a map of annual TRW for 2021, demonstrating that combining different data sources can lead to more effective models for forest growth, while also identifying areas where predictions may be less reliable, particularly in climate marginal zones.

Alzheimer's disease (AD) is a progressive memory loss and cognitive dysfunction brain disorder brought on by the dysfunctional amyloid precursor protein (APP) processing and clearance of APP peptides. Increased APP levels lead to the production of AD-related peptides including the amyloid APP intracellular domain (AICD) and amyloid beta (A), and consequently modify the intrinsic excitability of the hippocampal CA1 pyramidal neurons, synaptic protein activity, and impair synaptic plasticity at hippocampal CA1-CA3 synapses. The goal of the present study is to build computational models that incorporate the effect of AD-related peptides on CA1 pyramidal neuron and hippocampal synaptic plasticity under the AD conditions and investigate the potential pharmacological treatments that could normalize hippocampal synaptic plasticity and learning in AD.

Background: Siblings of children requiring palliative care are often forgotten and overlooked, as the focus tends to be on the ill child and their parents. Limited knowledge of non-bereaved siblings' perspectives makes it challenging to provide appropriate support for them. A review of existing literature is thus needed to better understand the experiences of these siblings and to identify research gaps that may require further examination.

The continuing attention of scholars and practitioners to the teaching profession, teachers and teaching is based above all on the fact that societal progress is impossible without an effective education system. Teachers are the "soft" dynamic, and at the same time, a driving force in this constantly changing system, and research into the prerequisites for their effective performance requires constant attention. In this study, the main phenomenon under analysis is the emotional resilience of teachers-the internal capacity to adapt, manage or cope with emotionally demanding situations.

The use of religious resources in helping victims of workplace mobbing.

Front Psychol

November 2023

Department of Theology, Faculty of Catholic Theology, Vytautas Magnus University, Kaunas, Lithuania.

Research shows that in providing assistance to individuals who have experienced psychological traumas, it is beneficial not only to take into account the specific religious spiritual needs but also to employ religious resources. Although the role of religious counsellors using various psychological theories in helping to cope with traumatising experiences is acknowledged, there is still a lack of a conceptualising approach to the possibilities of employing religious resources used in Christian spiritual assistance, seeking to help cope with the effects of workplace mobbing. Therefore, this study aims to conceptualise the perspective of integrating Christian spiritual assistance resources in overcoming the individual consequences of workplace mobbing.

Environ Sci Pollut Res Int

December 2023

Bioeconomy Research Institute, Vytautas Magnus university, Akademija, Kaunas Region, Studentu 11, LT-53361, Lithuania.

The aim of this study is to employ panel data approach to investigate determinants of total GHG emissions in all European Union (EU) economies in years 1990-2018 and evaluate the role of nuclear energy in climate change mitigation. It incorporates the following variables potentially affecting the greenhouse gas (GHG) emissions: economic-gross domestic product (GDP) per capita and GDP per capita squared to control for non-linear relationship between economic output and GHG emissions; structural-economic structure reflected in the share of manufacturing in total gross value added (GVA); energy-mix-share of nuclear power and renewable sources in total gross electricity production; environmental policy-the amount of environmental taxes (as a percentage of GDP) and the number of European Union Emission Trading System (EU ETS) allowances auctioned or sold (as a percentage of GDP per capita). The main findings of this study confirm the long-run relationship between GHG emissions, GDP level, and energy-mix variables.
