143. Sensitivity analysis, calibration and validation of a phenology model for Pityogenes chalcographus (CHAPY)Nikica Ogris, Mitja Ferlan, Tine Hauptman, Roman Pavlin, Andreja Kavčič, Maja Jurc, Maarten De Groot, 2020, original scientific article Abstract: A phenology model of Pityogenes chalcographus was developed. The model quite accurately simulates the seasonal dynamics of P. chalcographus. Sensitivity analysis revealed the most influential parameters. CHAPY was calibrated and validated for Slovenia. Development of the model revealed several knowledge gaps.

145. Možnosti zaznavanja drevesnih vrst v okviru Monitoringa gozdov in gozdnih ekosistemovAnže Martin Pintar, Robert Brus, Mitja Skudnik, 2020, original scientific article Abstract: Analizirali smo možnosti zaznavanja drevesnih vrst v okviru Monitoringa gozdov in gozdnih ekosistemov (MGGE) s poudarkom na manjšinskih in tujerodnih drevesnih vrstah ter možnosti zaznavanja razlik v pestrosti drevesnih vrst med posameznimi ekološkimi regijami. Zaznavanje minoritetnih in tujerodnih drevesnih vrst bi lahko izboljšali z obsežnejšim šifrantom drevesnih vrst, katerega dopolnitve smo predlagali. Take drevesne vrste bi zajeli z večjo verjetnostjo pri gostejši vzorčni mreži od obstoječe (4 km % 4 km). Opozorili smo tudi na pomen pravilne determinacije drevesne vrste na vzorčni ploskvi. V okviru MGGE smo ugotovili razlike v pestrosti drevesnih vrst med ekološkimi regijami; kot najpestrejša se je pokazala submediteranska ekološka regija.
Keywords: monitoring gozdov, gozdna inventura, seznam drevesnih vrst, manjšinske drevesne vrste, tujerodne drevesne vrste, pestrost drevesnih vrst, tree species diversity, non-native tree species

148. Post-fire effects on development of leaves and secondary vascular tissues in Quercus pubescensJožica Gričar, Polona Hafner, Martina Lavrič, Mitja Ferlan, Nives Ogrinc, Bor Krajnc, Klemen Eler, Dominik Vodnik, 2020, original scientific article Abstract: An increased frequency of fire events on the Slovenian Karst is in line with future climate-change scenarios for drought-prone environments worldwide. It is therefore of the utmost importance to better understand tree-fire-climate interactions for predicting the impact of changing environment on tree functioning. To this purpose, we studied the post-fire effects on leaf development, leaf carbon isotope composition (%13C), radial growth patterns and the xylem and phloem anatomy in undamaged (H-trees) and fire-damaged trees (F-trees) of Q. pubescens with good re-sprouting ability in spring 2017, the growing season after a rangeland fire in August 2016. We found that the fully developed canopy of F-trees reached only half of the LAI values measured in H-trees. Throughout the season, F-trees were characterised by higher water potential and stomatal conductivity and achieved higher photosynthetic rates compared to unburnt H-trees. The foliage of F-trees had more negative %13C values than those of H-trees. This reflects that F-trees less frequently meet stomatal limitations due to reduced transpirational area and more favourable leaf-to-root ratio. In addition, the growth of leaves in F-trees relied more on the recent photosynthates than on reserves due to the fire disturbed starch accumulation in the previous season. Cambial production stopped 3 weeks later in F-trees, resulting in 60% and 22% wider xylem and phloem increments, respectively. A novel approach by including phloem anatomy in the analyses revealed that fire caused changes in conduit dimensions in the early phloem but not in the earlywood. However, premature formation of the tyloses in the earlywood vessels of the youngest two xylem increments in F-trees implies that xylem hydraulic integrity was also affected by heat. Analyses of secondary tissues showed that although xylem and phloem tissues are interlinked changes in their transport systems due to heat damage are not necessarily coordinated.

150. Measuring techniques for concentration and stable isotopologues of CO2 in a terrestrial ecosystem : a reviewGrega E. Voglar, Saša Zavadlav, Tom Levanič, Mitja Ferlan, 2019, review article Abstract: Measurements of carbon dioxide and their stable isotopes are propulsive research tool in ecology and environmental science as they can give us insight into carbon cycle. They are widely used to investigate both natural and anthropogenic carbon sources in the atmosphere, hydrosphere and geosphere, as well as the exchange between these reservoirs. In this paper, we provide a basic overview of two different analytical measurement techniques, isotope ratio mass spectrometry (IRMS) and laser-absorption spectroscopy (LAS) which have been developed and utilized for monitoring of CO2 isotopologues in ecosystem. We present the basics for each technique, however with the emphasis on LAS measurement technique we are targeting readers who are not familiar with this topic. A major objective of this paper is to illustrate the current value and future potential of various analytical instruments in a wide range of applications deployed in the terrestrial ecosystem. Finally, we draw a conclusion from recent research campaigns by presenting a decision tree to better understand and choose a correct application combination for a selected scale of ecosystem.
Keywords: Isotope ratio mass spectrometry, laser-absorption spectroscopy, CO2 isotopologues, terrestrial ecosystem, decision tree, spectroscopic databases
