Effects of climate on leaf phenolics, insect herbivory, and their relationship in pedunculate oak (Quercus robur) across its geographic range in Europe
Elena Valdés‑Correcher, Yasmine Kadiri, Audrey Bourdin, Anna Mrazova, Flavius Balacenoiu, Manuela Branco, Michal Bogdziewicz, Mona Chor Bjørn, Thomas Damestoy, Jovan Dobrosavljević, Maarten De Groot, 2025, original scientific article

Abstract: An increase in biotic interactions towards lower latitudes is one of the most consistent patterns in ecology. Higher temperatures and more stable climatic conditions at low latitudes are thought to enhance biotic interactions, accelerating biological evolution and leading to stronger anti-herbivore defences in plants. However, some studies report contradictory findings, highlighting the need for further investigation into the underlying mechanisms. We used a combination of field observations and feeding trials in controlled environments to investigate the effect of climate on chemical defences and insect herbivory in pedunculate oak (Quercus robur L.) throughout most of its geographic range in Europe, while controlling for physical defences. The concentration of lignin, flavonoids, and total phenolics increased significantly with temperature, whereas both field herbivory and weight of spongy moth (Lymantria dispar L.) larvae were negatively influenced by temperature. Lignin concentration positively influenced the weight of spongy moth larvae whereas it had no effect on field herbivory. We found no evidence of strong positive relationships between insect herbivory and larvae growth with leaf defences. Our study underscores the complexity of plant–herbivore interactions along climatic gradients and highlights the need for further research to disentangle these intricate relationships.
Keywords: leaf chemical defences, Lymantria dispar, larvae biomass, pant–insect interactions

Verjetnostna napoved sanitarnega poseka smreke zaradi podlubnikov v Sloveniji v 2025
Nikica Ogris, Maarten De Groot, 2025, other scientific articles

Abstract: Naredili smo verjetnostno napoved sanitarnega poseka navadne smreke zaradi podlubnikov v 2025 v Sloveniji. Napoved smo naredili s pomočjo prostorskega modela, ki je bil razvit z logistično regresijo in ima ločljivost 1 km × 1 km. Napoved modela temelji na podatkih iz lanskega leta. Sanitarni posek smreke zaradi podlubnikov se bo v letu 2025 verjetno zgodil v 52,6 % modelskih celic s smreko. Med najbolj ogroženimi so naslednja gozdnogospodarska območja: Slovenj Gradec, Nazarje in Kranj.
