1. Ko lubadar postane zvezdar – ustaljenost terminologije kot temelj učinkovite komunikacije v gozdarstvuMaarten De Groot, Ana Brglez, Luka Capuder, Zina Devetak, Eva Groznik, Tine Hauptman, Nikica Ogris, Barbara Piškur, 2025, professional article Abstract: V času podnebnih sprememb, globalne trgovine in širjenja invazivnih organizmov je jasna, konsistentna in funkcionalna komunikacija med strokovnjaki, lastniki gozdov in javnostjo ključna za učinkovito gospodarjenje z gozdovi. Nedavna prizadevanja za posodobitev slovenskih imen podlubnikov, kot jih predlagajo Jurc in sod. (2024) v reviji Scopolia, odpirajo pomembno razpravo o strokovni ustreznosti, funkcionalnosti in ustaljenosti terminologije. S pričujočim komentarjem želimo opozoriti na pomen ohranjanja ustaljenih slovenskih poimenovanj, ki so v stroki uveljavljena že desetletja, ter predlagamo mehanizme za vzpostavitev strukturiranega procesa za usklajevanje slovenske terminologije.

2. Predlog optimalnega števila in lokacij kontrolno-lovnih nastav za prezimele osebke osmerozobegasmrekovega lubadarja ( Ips typographus ) v Sloveniji za leto 2026Nikica Ogris, Marija Kolšek, 2026, other scientific articles Abstract: Pripravili smo predlog optimalnega števila in lokacij kontrolno-lovnih nastav za prezimele osebke osmerozobega smrekovega lubadarja (Ips typographus) (nastave I. serije) za leto 2026. Pri pripravi smo sledili predlogu postopka za določitev optimalnega števila in lokacij kontrolno-lovnih nastav za osmerozobega smrekovega lubadarja. Predlagamo, da se nastave I. serije v letu 2026 položi na 107 lokacijah.

3. European beech decline in Slovenia is caused by a complex diseaseNikica Ogris, Ana Brglez, Andreja Kavčič, Janja Zajc Žunič, Maarten De Groot, Barbara Piškur, 2026, original scientific article Abstract: In recent decades, the average crown defoliation of European beech (Fagus sylvatica) in Central Europe has been steadily increasing, resulting in a decline in tree vitality. This study aimed to identify the key factors contributing to this deterioration. Forty healthy and 40 damaged European beech trees were felled on a systematic 16 × 16 km grid, and all tree parts were sampled for fungi and insects. Additionally, soil samples were collected for Phytophthora testing. Of 6400 cultured samples, 5828 fungal cultures were classified into 251 morphotypes. The twenty most frequent morphotypes from each tree part were selected for further molecular identification, revealing 44 different fungal taxa. The most frequently isolated fungal species were Neonectria coccinea, Neohendersonia kickxii, Apiognomonia errabunda and Aureobasidium pullulans—all well-known and common endophytes. Surprisingly, Phytophthora species were detected in only three of the 80 soil samples. The most frequent insect species were Orchestes fagi, Phyllaphis fagi, Psilocorsis reflexella and Phyllonorycter maestingella. The results indicate that the decline of European beech in Central Europe is driven by a multifaceted interplay of biotic and abiotic factors, with fungi playing the most significant role. Analysis revealed distinct differences in fungal and insect communities across sampled tree parts, but not between healthy and damaged trees. This finding is crucial, as it shows that healthy trees host endophytes that can exhibit pathogenic traits under external stress factors. Therefore, resilience and sustainability of beech will depend on mitigation of stressors and implementation of adaptive management strategies that address the evolving environmental challenges.

5. Preverjanje verjetnostne napovedi sanitarnega poseka smreke zaradi podlubnikov v Sloveniji v 2025Nikica Ogris, Maarten De Groot, 2024, other scientific articles Abstract: Preverili smo zanesljivost verjetnostne napovedi sanitarnega poseka smreke zaradi podlubnikov v Sloveniji v 2024. Verjetnostni model za napoved sanitarnega poseka smreke zaradi podlubnikov je potrdil visoko zanesljivost (AUC modela = 0,83, AUC napovedi = 0,83). Ugotovili smo optimalni prag za verjetnost sanitarnega poseka, ki ga bomo lahko uporabili pri naslednjih napovedih za bolj jasno določitev območij, kjer se bodo potencialno pojavila žarišča smrekovih podlubnikov. Napoved za leto 2024 smo naredili s pragom 0,45, ki pa se je izkazal za prenizkega, saj je bilo 24,1 % modelskih celic lažno pozitivnih. Optimalen prag za verjetnostni model v letu 2024 je bil 0,50, ki ga predlagamo za izdelavo vseh nadaljnjih verjetnostnih napovedih sanitarnega poseka smreke zaradi podlubnikov v Sloveniji.
