1741. Five-year monitoring of the ecological status of the Cymodocea nodosa meadow near the Port of KoperMartina Orlando-Bonaca, Diego Bonaca, Romina Bonaca, Erik Lipej, Domen Trkov, 2024, original scientific article Abstract: Seagrass meadows are among the most productive ecosystems in marine environments worldwide and are
often considered to symbolise near-pristine conditions on sedimentary bottoms, but their condition is associated to various types of anthropogenic stressors. In the Mediterranean Sea, Cymodocea nodosa is considered
an effective indicator of environmental change, due to its universal distribution, its sensitivity to various natural
and anthropogenic pressures, and the measurability of the species’ responses to these impacts. The aim of this
study is to present the improvement of the ecological status of the C. nodosa meadow near the port of Koper
over a period of five years and to compare these results with the reference site in the northern Adriatic Sea.
Keywords: Cymodocea nodosa, MediSkew index, Port of Koper, status assessment, northern Adriatic Sea

1742. Singular $p$-biharmonic problem with the Hardy potentialAmor Drissi, Abdeljabbar Ghanmi, Dušan Repovš, 2024, original scientific article Abstract: The aim of this paper is to study existence results for a singular problem involving the $p$-biharmonic operator and the Hardy potential. More precisely, by combining monotonicity arguments with the variational method, the existence of solutions is established. By using the Nehari manifold method, the multiplicity of solutions is proved. An example is also given to illustrate the importance of these results.
Keywords: p-biharmonic equation, variational methods, existence of solutions, Hardy potential, Nehari manifold, fibering map

1746. Uporabnost nacionalnih podatkov laserskega skeniranja in cikličnega aerofotografiranja pri zaznavanju gozdnih vrzeliAnže Martin Pintar, Mitja Skudnik, 2024, original scientific article Abstract: Gozdna tla zastirajo drevesne krošnje in gozdna vrzel je vsaka večja ali manjša površina tal, ki je ne prekrivajo krošnje zgornjega sloja dreves. Velikost vrzeli vpliva na to, katera drevesna vrsta se bo pomladila, pa tudi na vertikalno in horizontalno strukturo gozda. Na Pohorju (Pahernikova gozdna posest, za katero so značilni gozdovi, v katerih se na majhnih površinah pojavljajo drevesa različnih premerov in starosti) smo analizirali možnosti samodejnega zaznavanja vrzeli na podlagi podatkov Laserskega skeniranja Slovenije (LSS) in Cikličnega aerofotografiranja Slovenije (CAS). Uporabili smo digitalna modela krošenj (DMK), pridobljena iz obeh virov podatkov. Skupna natančnost zaznavanja tudi najmanjših vrzeli (manjših od 50 m2 ) na podlagi podatkov LSS je znašala 94,4 %, na podlagi podatkov CAS pa 83,1 %. Na podlagi podatkov LSS je mogoče zaznati večje število in površino vrzeli, prav tako so vrzeli, pridobljene na podlagi podatkov LSS, bolj razčlenjene in podolgovate. Zaznavanje vrzeli s podatki CAS in LSS je medsebojno bolj primerljivo pri najmanjših površinah vrzeli 100 m2 , natančnost zaznave takšnih vrzeli je 85,4 oziroma 94,4 %. Rezultati kažejo, da je ob odsotnosti podatkov LSS uporaba podatkov CAS za določanje vrzeli smiselna na velikopovršinski ravni in pri zaznavanju vrzeli, večjih od 100 m2 .
