721. Effects of biotic and abiotic stressors on asymmetries and head size in two sympatric lizard speciesAjša Alagić, Miha Krofel, Marko Lazić, Anamarija Žagar, 2020, complete scientific database of research data Abstract: Organisms face numerous environmental stressors, which can affect developmental precision. Developmental instability can be used as an efficient and reliable bioindicator of environmental stressors and individual health. However, little information is available about effects of interspecific interactions on occurrence of developmental instability. We analyzed fluctuating asymmetry in two sympatric lizard species (Iberolacerta horvathi and Podarcis muralis), which exhibit a competitive interaction, to determine potential effects of altitude, interspecific competition and urbanization on a set of physical characteristics. We sampled 16 syntopic and allotopic populations and used methods of geometric morphometrics to analyze head morphology. We detected significant effect of altitude, but the trend was not linear: lizards had most asymmetrical heads at mid altitudes, which could be related to lower availability of favorable lizard habitats (open areas) at this altitude and therefore higher competition. We observed that lizards from allotopic populations attained larger head sizes compared to lizards in syntopy that experienced interspecific competition. This could suggest that in sites where competing species is absent, individuals can invest more energy in the development of the body. Moreover, head shape of Iberolacerta horvathi was more asymmetric compared to Podarcis muralis, which could indicate difference between species in the vulnerability to stress effects. We did not detect any statistically significant effect of urbanization, which could relate to relatively low degree of pollution and habitat degradation in our study area. Our results highlight the possibility of using lizards and developmental instability for bioindication of environmental stressors.

723. Data from: Towards a functional understanding of species coexistence: ecomorphological variation in relation to whole-organism performance in two sympatric lizardsAnamarija Žagar, Miguel A. Carretero, Al Vrezec, Katarina Drašler, Antigoni Kaliontzopoulou, 2018, complete scientific database of research data Abstract: 1. We examined intra- and interspecific variation in functional morphology and whole-organism performance in a sympatric lizard species pair, Iberolacerta horvathi and Podarcis muralis, in the area with a high potential for competition. 2. The biggest variation between species was found in two functional traits, bite force and climbing speed, linked with corresponding morphological traits. 3. The species with larger and taller heads, P. muralis, exhibited correspondingly stronger bite forces. The other species exhibited smaller and flatter head. Both traits may potentially promote segregation between species in trophic niche (stronger bites relate to harder prey) and in refuge use (flatter heads allow using narrower crevices, hence, influencing escaping from common predators). Stronger bites and larger heads also provide one species with a dominant position in interspecific agonistic interactions. 4. Females had longer trunks that impacted negatively on climbing speed, which may lower anti-predator escape abilities of the more trunk-dimorphic species, but positively influence reproductive effort. 5. Our results exemplify how the joint examination of morphological and functional traits of ecologically similar and sympatric species can provide a mechanistic background for understanding their coexistence, namely syntopic populations that are frequent in the study area. 6. The identified roles of functional morphology in this system of sympatric rock lizards support the contribution of functional diversification for the complexity of community structure via coexistence.

724. Chloroplast redox state changes indicate cell-to-cell signalling during the hypersensitive response : version v3Tjaša Lukan, Kristina Gruden, Anže Županič, Tjaša Mahkovec Povalej, 2021, complete scientific database of research data Abstract: We performed detailed spatiotemporal analysis of chloroplast redox response to potato virus Y (PVY) infection in resistant Ny‐1-gene-bearing potato and its transgenic counterpart with impaired SA accumulation and compromised resistance. We found that the chloroplasts are highly oxidized in the cells adjacent to the cell death zone at different stages after virus inoculation in both genotypes. This hypothesis is further supported by highly induced formation of stroma filled tubules that extend from chloroplasts (stromules) in the cells adjacent to signalling cells. This dataset s a deposit of all the raw microscopy images of the study, plus the relevant metadata in ISA-tab compliant folder structure. After receiving reviews, we have made an additional experiment using a ROS inhibitor. The raw and processed data for this is in a separate file: _S_chlROS_inhibitor.zip

725. Po poteh vil in gradov : sprehod skozi zgodovinoDragica Čeč, Urška Bratož, Matic Batič, Oskar Opassi, Damjana Fortunat-Černilogar, Miha Mlinar, Vojko Pavlin, 2022, professional monograph Abstract: Publikacija predstavlja historične in umetnostnozgodovinske poudarke izbranih dvorcev in vil v zahodni Sloveniji, pri čemer se ne posveča zgolj najpomembnejšim arhitekturnim poudarkom, ampak poskuša zgodovino stavb in njihovih posameznikov razložiti v zgodovinskem kontekstu, v katerem so živeli. Izpostavlja posameznike, ki so s svojimi življenjskimi zgodbami in karierami pustili poseben pečat v svojem času, ustvarili zavidljive knjižne in umetniške zbirke in na svojih dvorcih gostili pomembne osebnosti. Gre namreč za okolje, ki je zaradi političnih sprememb na začetku 16. stoletja omogočilo predstavnikom številnih plemiških rodbin (Cobenzl, Lanthieri, Hofer, Rabatta, Thurn, Thurn-Valsassina, Herberstein, Edling, Dornberk, Coronini) hiter vzpon znotraj plemiške hierarhije zaradi diplomatskih in dvornih služb, od uspešnih diplomatov na cesarskem dvoru do spretnih rodbinskih in kariernih povezav, mnogi pa so svoj prestiž in ugled izkazovali tudi skozi podobe dvorcev, ki so predstavljeni v publikaciji. Ob izumrtju nekaj najpomembnejših novoveških rodbin so lastniki nekaterih dvorcev postali meščani in prav ti so spisali prav neverjetne znanstvene in karitativne zgodbe. Publikacija pomeni pregled obsežne obstoječe literature, pri določenih lokacijah (Žablje, Kozlov rob, Coronini, Lože, Rihemberk, dvorec Ravne pri Pivki, Šilentabor) pa so bile opravljene tudi nove raziskave.

730. Amphiphilic coumarin-based probes for live-cell STED nanoscopy of plasma membraneHana Kokot, Boštjan Kokot, Anja Pišlar, Hana Esih, Alen Gabrič, Dunja Urbančič, Rojbin El, Iztok Urbančič, Stane Pajk, 2024, original scientific article Abstract: Plasma membranes are vital biological structures, serving as protective barriers and participating in various cellular processes. In the field of super-resolution optical microscopy, stimulated emission depletion (STED) nanoscopy has emerged as a powerful method for investigating plasma membrane-related phenomena. However, many applications of STED microscopy are critically restricted by the limited availability of suitable fluorescent probes. This paper reports on the development of two amphiphilic membrane probes, SHE-2H and SHE-2N, specially designed for STED nanoscopy. SHE-2N, in particular, demonstrates quick and stable plasma membrane labelling with negligible intracellular redistribution. Both probes exhibit outstanding photostability and resolution improvement in STED nanoscopy, and are also suited for two-photon excitation microscopy. Furthermore, microscopy experiments and cytotoxicity tests revealed no noticeable cytotoxicity of probe SHE-2N at concentration used for fluorescence imaging. Spectral analysis and fluorescence lifetime measurements conducted on probe SHE-2N using giant unilamellar vesicles, revealed that emission spectra and fluorescence lifetimes exhibited minimal sensitivity to lipid composition variations. These novel probes significantly augment the arsenal of tools available for high-resolution plasma membrane research, enabling a more profound exploration of cellular processes and dynamics
