Biomonitoring in soil systems presents difficulties in retrieval and differentiation of test organisms from local populations. The aim of this study was to develop a simple method of in situ containment and efficient retrieval of earthworms. Visible Implant Elastomer (VIE) tags were used to identify earthworms Lumbricus rubellus and Aporrectodea caliginosa introduced to unpolluted pasture or a polluted site. Containment PVC tubes of different height (inserted differently into the soil and covered or not covered by a mesh) were used. Highest recovery rates for both species came from use of 0.3 m tubes (100% for A. caliginosa and 71% for L. rubellus). This study confirmed the feasibility of using VIE tags to identify and aid recovery of introduced earthworms from field experiments. Results suggested that recovery rates were influenced by behavioural differences in ecological groupings and site-specific factors. There is scope for further improvement in the tagging procedure, mortality assessment and investigation of containment for earthworms.
Psychological and neurodevelopmental implications of the COVID-19 pandemic in children and adolescents – a review of research and reports
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2022-12) Frączek, Paulina
The COVID-19 pandemic has affected the lives of people all over the world, including children and adolescents. Despite various clinical images of infection and potential long-term effects of it, there is a wide range of psychological implications resulting from stress, anxiety, and a feeling of helplessness rooted in containment measures and lockdowns. Children and adolescents, as a special group, need determined conditions to develop and learn. Proper development depends on contact with peers, a regular daily schedule, setting new challenges, and, above all, a sense of security that adults should provide. In the time of the global pandemic, these requirements are very difficult to meet. Consequently, we observe an increase in the frequency of appearance of mental disorders in the youngest groups. The article presents current data on the number and type of disorders described in children and adolescents associated with the COVID-19 pandemic, proposed diagnostic tools for these disorders, and recommendations for the management of a child in need of psychological intervention. The problem of neurodevelopmental disorders in children born during the pandemic is also shown. The article uses available, selected scientific studies and data from national and international reports.
