51. Spletna orodja za upravljanje s smrekovimi podlubniki : Web tools for management of Spruce Bark BeetlesNikica Ogris, 2020, professional article Abstract: V prispevku predstavljamo spletna orodja, s katerimi si lahko pomagamo pri upravljanju s smrekovimi podlubniki. Na voljo je več spletnih orodij, ki pomagajo pri načrtovanju spremljanja kontrolnih pasti in kontrolnih nastav, ki jih uporabljamo za ugotavljanje gostote populacij smrekovih podlubnikov. Na podlagi teh podatkov vsako leto ugotavljamo lokacije pasti, kjer so se podlubniki prenamnožili. Posledično moramo na takšnih lokacijah povečati obseg ukrepov in pospešiti izvajanje varstva gozdov pred podlubniki zaradi preprečevanja škode v gozdovih. Rezultate teh analiz objavljamo v spletni reviji Napovedi o zdravju gozdov. V okviru Javne gozdarske službe na Gozdarskem inštitutu Slovenije, tj. Poročevalsko prognostično-diagnostične službe za gozdove, vsako leto izdelamo kratkoročno napoved sanitarnega poseka smreke. Napoved je verjetnostna in pomaga pri bolj osredotočenem iskanju žarišč smrekovih lubadark; najprej iščemo žarišča na lokacijah, kjer je največja verjetnost pojava žarišč. Tako se poveča verjetnost, da žarišča najdemo še v zgodnji fazi napada, kar omogoči več časa za ukrepanje. Ko enkrat najdemo žarišče, nas zanima, koliko časa imamo za sanacijo. Za ta namen smo razvili spletno orodje, ki izračuna priporočeni rok za izvedbo ukrepov za zatiranje smrekovih podlubnikov. S tem orodjem si lahko postavimo prioritete za sanacijo žarišč lubadark, tj. najprej saniramo žarišča, katerim bo rok za izvedbo ukrepov potekel najprej. Izdelali smo tudi dolgoročno napoved sanitarne sečnje zaradi žuželk, ki je lahko v pomoč pri določitvi smernic za dolgoročno gospodarjenje s smreko in pri usmerjanju ciljne drevesne sestave v gozdnogospodarskih načrtih. Vsa navedena spletna orodja je razvil Gozdarski inštitut Slovenije in so javno dostopna na spletnem portalu Varstvo gozdov (www.zdravgozd.si).

52. Growth-limiting factors and climate response variability in Norway spruce (Picea abies L.) along an elevation and precipitation gradients in SloveniaJernej Jevšenak, Ivan Tychkov, Jožica Gričar, Tom Levanič, Jan Tumajer, Peter Prislan, Domen Arnič, Margarita Popkova, Vladimir V. Shishov, 2020, original scientific article Abstract: Norway spruce (Picea abies L.) is among the most sensitive coniferous species to ongoing climate change. However, previous studies on its growth response to increasing temperatures have yielded contrasting results (from stimulation to suppression), suggesting highly site-specific responses. Here, we present the first study that applies two independent approaches, i.e. the nonlinear, process-based Vaganov-Shashkin (VS) model and linear daily response functions. Data were collected at twelve sites in Slovenia differing in climate regimes and ranging elevation between 170 and 1300 m a.s.l. VS model results revealed that drier Norway spruce sites at lower elevations are mostly moisture limited, while moist high-elevation sites are generally more temperature limited. Daily response functions match well the pattern of growth-limiting factors from the VS model and further explain the effect of climate on radial growth: prevailing growth-limiting factors correspond to the climate variable with higher correlations. Radial growth correlates negatively with rising summer temperature and positively with higher spring precipitation. The opposite response was observed for the wettest site at the highest elevation, which positively reacts to increased summer temperature and will most likely benefit from a warming climate. For all other sites, the future radial growth of Norway spruce largely depends on the balance between spring precipitation and summer temperature.

For a meaningful estimation of ecosystem production and the cycling of water, energy, nutrients and carbon, the integration of soil processes and the exchanges at the surface is crucial. It is increasingly recognized that soil biota play an important role in soil organic carbon and nutrient cycling, shaping soil structure and hydrological properties through their activity, and in water and nutrient uptake by plants through mycorrhizal processes. In this article, we review the main soil biological actors (microbiota, fauna and roots) and their effects on soil functioning. We review to what extent they have been included in soil models and propose which of them could be included in ecosystem models. We show that the model representation of the soil food web, the impact of soil ecosystem engineers on soil structure and the related effects on hydrology and soil organic matter (SOM) stabilization are key issues in improving ecosystem-scale soil representation in models. Finally, we describe a new core model concept (KEYLINK) that integrates insights from SOM models, structural models and food web models to simulate the living soil at an ecosystem scale.
