Announcement of a workshop series – “Climate for Biodiversity”
In 2022–2023, the Institute of Dendrology of the Polish Academy of Sciences is carrying out a project titled “Climate for Biodiversity,” funded by the Ministry of Education and Science’s “Social Responsibility of Science” program (no. SONP/SP/513422/2021).
The goal of this project is to raise awareness of the Institute’s scientific activities and to share the findings of its research. As part of this initiative, our specialists have prepared a series of 18 workshops that will present—through accessible audiovisual and graphic materials—state-of-the-art techniques and research methods used in the Institute’s laboratories.
Very soon, these materials will be available on our website and on social media—here on Facebook, as well as on our YouTube channel.

We invite you to listen to Dr. Katarzyna Sękiewicz’s lecture entitled “Endemic species and climate change.”
Climate change is proceeding at an alarming rate, leading to a loss of biodiversity. An important component are endemic species, which are particularly vulnerable to these changes. Preservation and protection of endemic woody species is of the greatest concern. Due to their longevity, many trees may not be able to adapt to these changes. Therefore, the preservation of endemics that represent the unique biological heritage of an area is becoming a priority in global conservation strategy.

We invite you to listen to Dr. Anna Napierała-Filipiak’s lecture entitled “Elm trees, biodiversity, climate.”
Elm trees significantly affect the forest ecosystem, shaping the forest litter and undergrowth. Research in the Netherlands on a species of mountain elm has identified 79 species of insects associated with it, highlighting its contribution to biodiversity. Graphiosis and climate change are severely limiting the resources of these trees. Prolonged summer droughts and extreme temperature fluctuations in January and February pose serious threats, negatively affecting seedling development, flowering and seed setting. Protecting against disease and adapting to a changing climate are becoming crucial to maintaining their ecosystem role.

We invite you to listen to Dr. Krzysztof Ufnalski’s lecture entitled “Contribution of late wood in pines from Scandinavia.”
In 2012, Prof. Jacek Oleksyn organized an expedition to Scandinavia, continuing the research of Swedish scientist Nils Sylvén conducted 100 years ago. The characteristics of pine trees growing from the 56th to 68th degree of north latitude were analysed. Based on data collected from 53 plots, we analysed the characteristics of trees, taking into account age, width of annual growth, and the proportion of early and late wood. The study showed that the proportion of late wood in annual growth decreases in the northern direction, which may be due to the shorter growing season and lack of time for the maturation of late wood cells. The length of the growing season explains 48% of this variation. Average annual temperatures in the study areas explain 44% of the variation in the proportion of late wood.

We invite you to listen to Prof. Adam Boratyński’s lecture entitled “Junipers around the Mediterranean.”
The juniper genus evolved before about 50-60 million years ago, under hot and dry climate conditions. Today, about 100 taxa of junipers are known, grouped into three sections that are the three oldest clades in molecular analysis. Junipers are light-demanding, drought-tolerant plants, with individual species adapted to broad range of temperatures. There are 20 species and subspecies of junipers around the Mediterranean, representing all 3 sections.
