Abstract: The scientific monograph THINKING TOGETHERNESS. PHENOMENOLOGY AND SOCIALITY, edited by Dr. Andrej Božič, comprises the contributions of 32 scholars from the field of phenomenological philosophy. The international and intergenerational configuration of the whole, within which the chapters are meaningfully arranged into seven thematic sections, imparts upon the volume the character of a panoramic scrutiny of the phenomenological manner of confronting the question what co-constitutes the fundamental traits of inter-personal co-habitation with others. The volume offers not only a historical account with regard to the development of phenomenology, but also quite straightforwardly concerns its relevance within the philosophical research that deals with the contemporary problems of society.

Abstract: Adriano Fabris nas v knjigo uvede s kritiko današnjih predstav o prehranjevanju in odnosu do jedi. Etika uživanja hrane ni povezana niti s temi, ki prepotujejo kilometre, da pridejo do lokala s slow food, niti s temi, ki so zadovoljni z goltanjem sendvičev iz restavracij s fast food. Prav tako ne zadeva obnašanja teh, ki prepovedujejo določeno hrano ali fetišizirajo določene vire hrane, kot so borci za pravice živali, vegetarijanci in vegani. Zadeva tiste, ki se zavedajo, da jesti pomeni odnos do vsega, kar nas lahko nahrani: spoštljiv, uravnotežen odnos, ki upošteva mnogotere vezi, v katere je vpleteno vsako živo bitje. To je delovanje tistih, ki razumejo, da je treba regulirati svojo željo in ne potrebe po prehranjevanju. V drugem poglavju avtor obravnava različne načine reguliranja prehranjevanja s predpisovanjem tega, kaj na bo dovoljeno jesti in kaj ne. V ozadju teh predpisov, zapovedi in prepovedi se kot specifični znak naše omejenosti pojavlja nezmožnost, da bi asimilirali vse, torej povsem zaužili tisto, s čimer se prehranjujemo, s čimer je povezana tudi potreba po puščanju ostankov in odpadkov. V tretjem poglavju je začrtana etiko uživanja hrane, ki izhaja iz predpostavke, da obstoj hrane implicira, spodbuja in izvršuje odnose ter da je prehranjevanje samo odnos. Na to se navezuje vprašanje, ali je za prehranjevanje samega sebe neizogibno izvajati nasilje nad drugimi organizmi. Etični vidik se oblikuje ob predpostavki odgovornega odnosa do živih bitij, ki ne vključuje le nas ljudi, marveč celoten ekosistem. Knjigo zaključuje manjši priročnik (dekalog), ki naj bi z normativnim pristopom usmerjal naše konkretne izbire v pri prehranjevanju. Od naše izbire je odvisno, ali bomo z etično motivirano izbiro dejansko spremenili naš odnos do prehranjevanja. Če bomo to storili, bo to prvi korak k uveljavitvi še bolj splošnih sprememb v našem odnosu do sveta in k odgovorni delitvi skupnega prostora z drugimi živimi bitji.

Abstract: To gain insight into the current population trends of Carabus variolosus nodulosus in Slovenia and assess the body condition of individuals, data from 17-year monitoring program were analyzed across five geographically distinct regions. The number of beetles captured per trap was recorded, and measurements of live specimens were taken to calculate both national and regional population trends, along with a body condition index. Additionally, linear mixed-effects models were used to examine the potential impact of sex and disturbances on body condition, and to explore the correlation between body condition and population density. The results indicated an overall stable population trend with marked regional differences. No correlation was found between body condition and population density or disturbances, though significant differences in body condition between sexes were observed. This study underscores the importance of long-term and multi-scale monitoring to detect stress factors and potential local extinctions that might otherwise remain undetected and proposes sampling efforts for future monitoring schemes for reliable trend assessments of the species.

Abstract: High altitude imposes several extreme constraints on life, such as low oxygen pressure and high levels of ultraviolet radiation, which require specialized adaptations. Many studies have focused on how endothermic vertebrates respond to these challenging environments, but there is still uncertainty on how ectotherms adapt to these conditions. Here, we used whole-genome sequencing of low-altitude (100–600 m) and high-altitude (3,550 m) populations of the wide-ranging Tenerife lizard Gallotia galloti to uncover signatures of selection for altitudinal adaptation. The studied populations show reduced differentiation, sharing similar patterns of genetic variation. Selective sweep mapping suggests that signatures of adaptation to high altitude are not widespread across the genome, clustering in a relatively small number of genomic regions. One of these regions contains BMPER, a gene involved with vascular remodeling, and that has been associated with hypoxia-induced angiogenic response. By genotyping samples across 2 altitudinal transects, we show that allele frequency changes at this locus are not gradual, but rather show a well-defined shift above ca. 1,900 m. Transcript and protein structure analyses on this gene suggest that putative selection likely acts on noncoding variation. These results underline how low oxygen pressure generates the most consistent selective constraint in high-altitude environments, to which vertebrates with vastly contrasting physiological profiles need to adapt in the context of ongoing climate change.

Abstract: Physico-chemical properties of microplastics (MPs) change during weathering in the environment. There is a lack of knowledge about the effects of such environmentally relevant MPs on organisms. We investigated: 1) the physico-chemical changes of MPs due to UV–VIS weathering, and 2) compared the effect of pristine and aged MPs on the behaviour of the water flea Daphnia magna and terrestrial crustacean Porcellio scaber. Dry powders of MPs were produced from widely used polymer types: disposable three-layer polypropylene (PP) medical masks (inner, middle and outer), polyester textile fibres, car tires and low-density polyethylene (LDPE) bags and were subjected to accelerated ultraviolet–visible (UV–VIS) ageing. Our results show that the extent of transformation depends on the type of polymer, with PP showing the most changes, followed by LDPE, textile fibres and tire particles. Obvious fragmentation was observed in PP and textile fibres. In the case of PP, but not polyester textile fibres, changes in FTIR spectra and surface properties were observed. Tire particles and LDPE did not change in size, but clear changes were observed in their FTIR spectra. Most MPs, aged and pristine, did not affect the swimming of daphnids. The only effect observed was a significant increase in path length and swimming speed for the pristine tire particles when the recording was done with particles remaining in the wells. After transfer to a clean medium, this effect was no longer present, suggesting a physical rather than chemical effect. Similarly, woodlice showed no significant avoidance response to the MPs tested, although there was a noticeable trend to avoid soils contaminated with pristine polyester textile fibers and preference towards the soils contaminated with aged MP of the middle mask layer. Overall, the apparent changes in physico-chemical properties of MPs after accelerated ageing were not reflected in their effects on woodlice and daphnids.
