February 24, 2025 Discovery of Natural Recovery
Danish cases on natural forest recovery
The third case study
The hurricane forest, Bornholm- Storm 1967
The second case study
Thy National Park, Stenbjerg Plantage - Forest fire in 2013
The first case study
Lovrup Skov - The storm in 1999 that destroyed the forest climate
Natural disturbances are an
important part of forest dynamics and create niches for many species to sustain
and for interesting forest images.
Our research into natural
recovery after disturbances takes place in some managed forests, which have
been heavily impacted by natural disturbances, i.e. Sønderjylland (storm 1999),
Thy (fire 2013), Bornholm (storm 1967).
After the disturbances, these
forests have been left for natural succession, so that the structures and
processes that support or inhibit the natural recovery can be studied.
In the cases we studied, we can
see that that salvaging the wood after disturbances, poorer site conditions and
deer browsing, inhibit natural recovery.

The presence of pre-disturbance
legacies, in the form of surviving trees, advanced regeneration and deadwood
support the recovery of the forest.

Under certain
conditions, natural recovery can be a viable alternative for forest recovery in
Denmark.

February 14, 2025 Brevkassen Spørg om Fysik: Om energier ved kvantespring
Vi har fået et spørgsmål, som er helt i Niels Bohrs ånd, det handler nemlig om atomfysik. Niels Bohr, han er jo kendt for at komme med en model af atomet, som kan forklare rigtigt meget om kvantemekanik.
Modellen minder lidt om solsystemet, hvor man har en positiv ladet kerne, en kompakt kerne, som er omgivet af elektroner, som sidder i forskellige energitilstande. Hvis man tilfører atomet noget energi, så kan man få en elektron til at ryge op i en anden energitilstand.
Og så kan den sidde der lidt, og så falde ned igen, og så udsende energien som en ny foton. Men energien af den foton, der kommer ind, den skal matche fuldstændig energiforskellen mellem de to energitilstande.
Hvis den har lidt for høj energi, eller hvis den har lidt for lav energi, så ryger den lige igennem. Og vi har så fået et spørgsmål fra Steen, som spørger: Er det virkelig rigtigt, at den energi som fotonen har, skal matche 100% energiforskellen mellem tilstanden her?

February 12, 2025 Interview med Dorthe Dahl-Jensen om EGRIP-projektet
I januar 2025 samledes omkring 80 forskere i København i et ugelangt symposium for at fremlægge deres resultater fra EGRIP-projektet. Det foregik i Videnskabernes Selskab, og var et resultat af 9 års feltarbejde på den Grønlandske indlandsis, dog afbrudt af 2 års COVID i 2020 og 2021.
Omkring halvdelen af de 80 fremmødte kommer fra fra Canada, USA, Japan, Korea og de fleste lande i Europa, og det er lige præcis hvad der er plads til i Videnskabernes Selskab.
Efter syv års boring var de gennem 2670 meter indlandsis nede ved grundfjeldet, og nu havde projektet nået sin afslutning, altså den del af projektet, der foregår ude i felten.
