NASLOV: Obnova gozdičkov rjavih alg iz rodu Cystoseira
--------------------------------------------------------------------------------------------------------------------------
Rjave alge iz rodu Cystoseira s.l. (vključujoč rodove Cystoseira, Gongolaria in Ericaria) so pomembni gradniki habitata v Jadranskem morju in tudi širše v Sredozemskem morju. Za njih je značilna razvejana tridimenzionalna struktura steljke, ki tvori t.i. krošnje, te pa se združujajo v prave podvodne gozdičke. Ti podvodni gozdički so po pomembnosti in številu vrst lahko primerljivi celo z gozdovi na kopnem in nudijo številne ekosistemske storitve kot so visoka primarna produkcija, dolgotrajni ponor ogljika in zaščita obalnega pasu pred vremenskimi vplivi. Krošnje cistozir nudijo tudi življenjski prostor bogati ribji in nevretenčarski združbo, substrat za številne vrste epifitov, vir hrane za številne organizme in jasli za ribje mladice. Zaradi antropogenih pritiskov kot so prelov velikih predatornih rib, gradnja v obalnem pasu, onesnaževanje in evtrofikacija voda ter segrevanje morja so populacije cistozir v zadnjih desetletjih v upadanju. Zaradi slabe širitvene kapacitete, fragmentiranih populacij in intenzivne paše s strani morskih ježkov in rastlinojedih rib je naravna obnova populacij malo verjetna. Dobro organizirani in usmerjeni obnovitveni ukrepi so tako nujni za ohranitev teh pomembnih habitatov.

Mikroalge so zelo raznolika skupina mikroskopskih organizmov, ki jih najdemo tako v morskih, kot sladkovodnih okoljih. Tvorijo osnovo prehranjevalnih mrež številnih ekosistemov. Poleg taksonomije merila za razvrščanje mikroalg v skupine vključujejo tudi njihove morfološke, fiziološke in ekološke značilnosti. Glavne taksonomske skupine morskih mikroalg, tako po številu vrst kot po številčnosti, so diatomeje, dinoflagelati, kokolitoforidi in druge haptofiti, kriptofiti, enocelične zelene alge in cianobakterije. Tretja največja skupina mikroalg - kokolitoforidi - je skupina, za predstavnike katere je značilen zunanji skelet iz kalcitnih ploščic (CaCO3) različnih oblik – kokolitov. So pomemben primarni producent, ponor ogljika, imajo pa tudi pomembno vlogo pri biološki ogljični črpalki (BCP).

Predavatelj: Timotej Turk Dermastia
------------------------------------
Timotej Turk Dermastia is a marine biologist who transformed into a microbiologist during the course of his PhD. Currently, he is conducting postdoctoral research in the field of diatom interactions with their viruses and methods for the detection and characterization of novel diatom viruses. His PhD at MBP-NIB was focused on diatoms of the genus Pseudo-nitzchia, which is one of the most common diatoms encountered in the world's oceans but is also one of the few diatom genera that are occasionally harmful to the environment and humans due to the production of a toxin called domoic acid. During the PhD, under the supervision of Associate Professor Patricija Mozetič, he was a FEMS fellow in Banyuls-sur-Mer, France, and has received a Fulbright Postdoctoral fellowship, which will be conducted next year.

NASLOV: Diatoms and their complex network of interactions with their pathogens, simbionts, grazers and ecosystem as a whole.
--------------------------------------------------------------------------------------------------------------------------
Diatoms are one of the world's most important phytoplankton groups, responisble for roughly 40% of the total phytoplankton primary production. They typically form spring blooms, where they accumulate enormous biomass. They form important ecological interactions with numerous links in the food chain. Harmful diatoms in the genus Pseudo-nitzschia affect the ecosystem up to the top by forming a bioacumulating toxin domoic acid, capable of inducing mass mortality events in marine vertebrates. Most diatoms also produce compounds that impair the reproduction of zooplankton. Lately, viruses and bacteria associated with diatoms have also become the subject of studies worldwide as they show to have yet unaccounted for and very important ecological roles. In this seminar we will these exciting studies and look to the future for things yet to be discovered.

NASLOV: Economic impact of parasites/diseases on a highly popular fish species in Norway
--------------------------------------------------------------------------------------------------------------------------
The focus of my talk will be on the economic impact of parasites/dieases on a highly popular fish species in Norway, the Atlantic salmon (Salmo salar) and the Gyrodactylus salaris parasite. I will present how to measure the impact by using revealed preferences method (travel cost method) and the cost-benefit ratio of eradicating the parasite. G. salaris was introduced in Norway in 1975 by the fish- farming industry, and infected more than 50 rivers out of the 400 rivers with atlantic salmon.
petek, 27. oktober 2023 Martin Vodopivec: Meduze in numerično modeliranje
V sredo, 8. novembra 2023, bo izveden 3. seminar iz morskih vsebin.
ČAS IN PROSTOR: Predavanje bo potekalo v Livadah 1.0 (Livade 6, Izola), predavalnica Epsilon (pritličje), od 12. do 13. ure.
------------------------------------
Predavatelj: Martin Vodopivec
------------------------------------
Lecturer studied physics at the University of Ljubljana and graduated with a thesis on the influence of giant molecular clouds and dark matter halos on the distribution of stars in our galaxy. After graduation, however, he was allowed to join a group of researchers working on the development of a chain of numerical ocean models. The project was a collaboration between the Agency of Environment and the National Institute of Biology, where he became more and more involved with marine biology. This led to a PhD thesis on the influence of offshore platforms on the Adriatic moon jellyfish population and a shift in his career towards biophysical modelling. He is currently head of the physical oceanography sub-unit at the Marine Biology Station Piran and is in charge of in situ oceanographic measurements and satellite data analysis. He is working on a coupled physical-biogeochemical model of the Adriatic Sea, focusing on the role of jellyfish in the ecosystem, and developing an individual-based model of Pelagia noctiluca (mauve stinger jellyfish).
--------------------------------------------------------------------------------------------------------------------------
NASLOV: Meduze in numerično modeliranje
--------------------------------------------------------------------------------------------------------------------------
Jellyfish are widespread throughout the world's oceans and are expected to thrive under projected future ocean changes (i.e., warming, acidification, oxygen depletion) and increased ocean exploitation (i.e., overfishing, maritime transport, marine infrastructure development). Due to their adaptability and simplicity, they are ubiquitous in various marine ecosystems and, under favorable conditions, form massive blooms that significantly disrupt the ecosystem. I will present two coupled physical-biological models of jellyfish population dynamics. Both are based on particle-tracking algorithms which were modified to incorporate individual based models. One was developed to elucidate the impact of offshore gas platforms on the population of the moon jellyfish (Aurelia aurita s.l.) in the Adriatic Sea, the other to better understand the occurrence of mauve stinger (Pelagia nociluca) in different parts of the Mediterranean Sea. The latter is still under development and I will present some preliminary results.

NASLOV: Marine Microbes in the sea of change
---------------------------------------------------------------------------------------------------------------------------------------
POVZETEK: Oceans and seas constitute the largest part of Earth's biosphere, and their smallest inhabitants – microbes - are invisible to the naked eye, but account for most of the ocean’s biomass and are the most productive and diverse members of marine food webs. The key factor contributing to the cosmopolitan distribution of microbes in oceanic habitats is the plasticity of their genomes (and thus their adaptability) and the different types of metabolic processes, some of which unique to microbes. In seawater, the pool of organic matter (OM) is composed of a plethora of chemical compounds of different origins, characterized by different size, complexity, availability, and reactivity. Through a chain of biochemical reactions, all particulate OM is eventually transformed into dissolved OM, which is almost exclusively accessible to microbes that operate various metabolic networks, and in this way, drive biogeochemical cycles at the base of the oceanic food web. The abundance, metabolic activity, and composition of microbial communities are influenced by a range of physical, chemical, and biological parameters, as well as by various interactions among organisms. Marine microbes are subject to constant fluctuations in environmental parameters, especially in coastal areas, and the resulting changes in microbial community dynamics affect the structure and functioning of marine ecosystems. Natural and anthropogenic influences are paving the way for projected changes in future oceans and will likely inevitably impact marine life, microbes, and the biogeochemical cycles they drive. However, the complexity, underlying mechanisms, and consequences of these processes remain unclear. Recent methodological advances in analytical chemistry and "omics" technology are providing insights into the relationship between individual compounds within the complexity of the OM pool and the metabolic network operated by the microbial community under specific environmental conditions. Only when we have gained this mechanistic understanding will we be able to predict the response of the marine ecosystem to natural and anthropogenic perturbations.

NASLOV: "Plant mating systems response to rapid environmental change – examples of contemporary evolution and adaptive phenotypic plasticity".
----------------------------------------------------------------------------------------------------------------------------------------
About the seminar: I will summarise two research projects investigating different mechanisms of plant mating system adaptation to rapid environmental variation. The first one explores contemporary evolution in entomophilous, short-lived arable weeds in response to climate change and pollinator decline using the resurrection approach. This approach consists of resurrection ancestral genotypes harvested in natural populations in the past and stored in seed repositories for several generations, then growing them side-by-side with their contemporary descendants harvested in the same population at present. The second one explores the adaptive value of plastic cleistogamy; a mixed-mating system where plants produce variable proportions of closed (cleistogamous) flowers which are obligately self-pollinated, and open, chasmogamous flowers which are potentially outcrossed. I investigate how cleistogamy varies between natural populations coming from contrasting climates and habitats, whether this variation is due to plasticity or genetic differentiation, and whether it confers an adaptive reproductive advantage in response to environmental variation.
