741. Nevarnosti v morju, ki večinoma to nisoVesna Flander-Putrle, Alenka Malej, Manja Rogelja, 2020, druge monografije in druga zaključena dela Povzetek: Morske trave niso alge, temveč spadajo med cvetnice. Od okoli 60 vrst, ki obstajajo na svetu, samo 4 izvorno uspevajo v Evropi – in vse najdemo tudi v slovenskem morju. To so: prava morska trava (Zostera marina), mala morska trava (Zostera noltii), kolenčasta cimodoceja (Cymodocea nodosa) in pozejdonka (Posidonia oceanica). Za vse so značilni tanki, ozki in dolgi listi. Pri nas tvori največje in najgloblje travnike kolenčasta cimodoceja (Cymodocea nodosa). Prisotnost morske trave je pokazatelj dobre kakovosti obalnega morja, travniki pa so pomemben habitat za številne organizme.

742. Čudovita pestrost živegaMojca Pibernik, Blaž Koderman, Danilo Bevk, 2020, druge monografije in druga zaključena dela Povzetek: Biotska pestrost (tudi biotska raznolikost, biotska raznovrstnost, biodiverziteta) je raznolikost živih bitij. Vključuje vse rastline, živali in druge organizme. Vsi organizmi so med seboj tesno povezani in se med seboj dopolnjujejo, sami pa ne bi mogli preživeti. Tudi ljudje smo kot del narave močno odvisni od biotske pestrosti, zato je pomembno, da se njenega pomena zavedo že otroci.
Ključne besede: biodiverziteta, otroci, pestrost živega, LIFE Naturaviva

744. Application of a metric for complex polynomials to bounded modification of planar Pythagorean-hodograph curvesRida A. M. T. Farouki, Marjetka Knez, Vito Vitrih, Emil Žagar, 2025, izvirni znanstveni članek Povzetek: By interpreting planar polynomial curves as complex-valued functions of a real parameter, an inner product, norm, metric function, and the notion of orthogonality may be defined for such curves. This approach is applied to the complex pre-image polynomials that generate planar Pythagorean-hodograph (PH) curves, to facilitate the implementation of bounded modifications of them that preserve their PH nature. The problems of bounded modifications under the constraint of fixed curve end points and end tangent directions, and of increasing the arc length of a PH curve by a prescribed amount, are also addressed.
Ključne besede: complex polynomials, inner product, norm, metric, Pythagorean-hodograph curves, bounded modification

746. Begomovirusi uvrščeni v točko 13.F. Priloge II Uredbe 2019/2072/EUZala Kogej Zwitter, Nataša Mehle, 2021, druge monografije in druga zaključena dela Povzetek: Virusi iz rodu begomovirusov (družina Geminiviridae) lahko okužijo številne vrste rastlin. Opisanih je več kot 400 različnih begomovirusov, od tega jih več kot 200 lahko okuži bučevke in/ali paradižnik. Vsi begomovirusi z izjemo Abutilon mosaic virus, Sweet potato leaf curl virus, Tomato leaf curl New Delhi virus, Tomato yellow leaf curl virus, Tomato yellow leaf curl Sardinia virus, Tomato yellow leaf curl Malaga virus in Tomato yellow leaf curl Axarquia virus, so uvrščeni v točki 13. F priloge II/A Uredbe 2019/2072/EU.

748. ICPP 2023 Satellite event: high-throughput sequencing in plant virology: from discovery to diagnostics (Sunday, 20 August 2023 – all day) : Lyon, France2023, druge monografije in druga zaključena dela Povzetek: High-throughput sequencing (HTS) technologies have revolutionized plant virus research and diagnostics by accelerating the discovery of new viruses and by providing a sensitive untargeted approach for the detection of viruses. The latter, together with high data-generation potential of HTS, enables discovery of new and emerging viruses from diverse hosts, archived or ancient samples, and untargeted virus detection in diverse matrices, as well as research on a broad range of topics, such as plant virus epidemiology, diversity, and evolution. Many new plant virus discoveries, increased availability of sequence data, and a lagging biological characterization of HTS-based findings call for a broad consideration on harmonization of sequencing and data analysis approaches, as well as the interpretation of the results from the scientific and regulatory perspective. During this satellite meeting, different aspects of applying HTS in plant virology will be addressed and discussed. Topics will include: discovery and detection of new and emerging viruses; virus diversity, epidemiology, and evolution studies; development of virus detection and identification protocols and validation of HTS-based tests for plant virus diagnostics.
