Rare earth elements and yttrium in cold mineral and thermal (~30-60 °C) waters from Tertiary aquifers in the Mura Basin, north-eastern Slovenia: a review
Polona Kralj, 2022, review article

Abstract: Cold mineral and thermal waters from Tertiary aquifers in the Mura Basin mainly belong to the Ca-(Mg)-(Na)-HCO3 and Na-HCO3 hydrogeochemical facies, respectively, and the concentrations of yttrium (Y) and lanthanides or rare earth elements (REEs) are far below (10-2 – 10-4) the abundances in the aquifer sediments. Mineral waters are high pCO2, and the plots of concentrations of YREEs normalised to Post Archean Australian Shale (PAAS) show fractionation of Y and heavy REEs (HREEs) over light REEs (LREEs), and a significant positive europium (Eu) anomaly. Thermal water from regionally developed aquifer Thermal I (recently also termed the Mura/Ujfalu Formation aquifer) shows a similar PAAS-normalised pattern with an obvious positive Eu anomaly and the tendency of enrichment with middle REEs (MREEs). The plots of PAAS-normalised YREE concentrations in thermal waters from the underlying low-permeability aquifers with poorly developed fracture porosity and abundant CO2 are flat with insignificant positive Eu anomaly. The abundance and fractionation of YREEs in mineral and thermal waters seems to be mainly controlled by the presence of carbonate complexing ligands, permeability of the aquifers and the related time of water-rock interaction.

River distance, stand basal area, and climatic conditions are the main drivers influencing lying deadwood in riparian forests
Janine Oettel, Martin Braun, Marcus Sallmannshofer, Maarten De Groot, Silvio Schueler, Charlotte Virgillito, Marjana Westergren, Gregor Božič, Laszlo Nagy, Srdjan Stojnić, Katharina Lapin, 2022, original scientific article

Abstract: Riparian forests are among the most diverse terrestrial ecosystems, yet their biodiversity is increasingly threatened by habitat degradation, climate change, river regulation and invasive species. We investigated deadwood, widely recognized as an indicator for forest biodiversity, in riparian forests of the Mura-Drava-Danube Transboundary Biosphere Reserve. The Biosphere Reserve is a conservation area that spans five countries and three rivers located in south-eastern Europe. In detail, we analyzed the drivers of lying deadwood volume, occurrence and decay related to floodplain type, silvicultural management, and climatic conditions using regression models. Lying deadwood occurrence and volume significantly decreased as distance from the river edge increased, indicating that river dynamics likely play a role in deadwood accumulation in riparian forests. Deadwood volume was also positively influenced by stand basal area, a parameter that can be directly addressed by silvicultural management. Deadwood decay was affected positively by temperature and negatively by precipitation, highlighting the importance of climatic conditions on decay progression. However, in order to draw more accurate conclusions about the drivers and dynamics of deadwood in riparian forests, further monitoring efforts that consider river flooding and flow regime, deadwood transport and saproxylic organism activity in addition to forest management and site conditions, are needed.

Podpora lokalnega prebivalstva izvajanju naravovarstvenih ukrepov v območjih Natura 2000 poplavnih gozdov Mure
Kaja Plevnik, Anže Japelj, 2021, original scientific article

Abstract: Reka Mura je v svojem celotnem toku vključena v omrežje območij Natura 2000, a so hkrati predeli teh območij v neugodnem ohranitvenem stanju, kar je posledica preteklih hidromelioracijskih ukrepov, onesnaženja voda in krčenja gozdov za nove kmetijske površine. Z javnomnenjsko anketo med prebivalstvom desetih krajev v okolici pilotnih območij Gornje Bistrice in Murske šume (junij–julij 2015; N = 303) smo želeli ugotoviti poznavanje različnih naravovarstvenih režimov, dojemanje omejitev za lastnike zemljišč, mnenje o pritiskih ljudi na poplavne gozdove ter podporo do štirih varstvenih ukrepov za izboljšanje ohranitvenega stanja gozdnih habitatnih tipov v obeh pilotnih območjih. Ugotovili smo relativno dobro poznavanje območij s posebnim režimom upravljanja, splošno strinjanje, da so omejitve v teh območjih pomembne, in da je večinsko prepričanje, da lastnikov zemljišč ne omejujejo precej oziroma zelo ter da poplavni gozdovi ob Muri niso izrazito niti izpostavljeni niti ne-izpostavljeni pritiskom družbe. Na podlagi podpore varstvenim ukrepom – (1) odstranjevanje tujerodnih invazivnih vrst; (2) sajenje vrbe in jelše v habitatih vidre in bobra; (3) osnovanje sestojev avtohtonih drevesnih vrst; (4) povečevanje količine odmrle drevesne biomase v habitatih saproksilnih hroščev – je bilo anketirance mogoče razvrstiti v tri razrede z različnimi preferencami do izvajanja ukrepov. V vseh treh razredih so vprašani izrazili pozitivne preference do večje površine sestojev z avtohtonimi drevesnimi vrstami, v enem do odstranjevanja invazivnih vrst in v enem do vzpostavitve stabilnega stanja populacije saproksilnih hroščev. V dveh razredih so izrazili negativne preference do povečevanja populacije bobra in vidre in hkrati do odstranjevanja invazivnih vrst. Presenetljiva je predvsem ugotovitev, da so bili anketirani bolj naklonjeni stabilizaciji populacij saproksilnih hroščev kot povečevanju populacij bobra in vidre, kar si razlagamo tudi tako, da lahko bober in vidra človeku povzročata škodo (vidra z lovljenjem rib, bober s škodo na kmetijskih pridelkih in na drevju).

Participativni pristop pri pripravi upravljavskih načrtov na primeru izbranih gozdnih habitatnih tipov in živalskih vrst ob Muri
Andreja Ferreira, Petra Grošelj, Špela Planinšek, 2021, original scientific article

Abstract: Evropska komisija za območja Natura 2000 priporoča izdelavo upravljavskih načrtov, ki vključujejo lokacijsko specifične cilje in na njih temelječe ukrepe ohranjanja narave. Da bi se izognili morebitnim poznejšim konfliktom, je treba v proces pravočasno in smiselno vključiti vse zainteresirane deležnike. V okviru projekta GoForMura sta bila kot vzorčni primer oblikovana upravljavska načrta za gozdni območji Natura 2000 na študijskih območjih Gornja Bistrica in Murska šuma v Prekmurju. Posebno težo v procesu nastajanja prvih tovrstnih dokumentov je imelo sodelovanje zainteresiranih deležnikov, še posebej lastnikov oz. upravljavcev gozdov.
