Chick feeding in common diving petrels (Pelecanoides urinatrix exsul) and South Georgia diving petrels (P. georgicus) was studied on Bird Island, South Georgia. Complete chick meals removed from the proventriculus of adults averaged 25.5 g (n = 32) for common diving petrels (17.6% of adult mass) and 23.3 g (n = 24) for South Georgia diving petrels (20.2% of adult mass); neither contained stomach oils. The sum of the positive mass increments during overnight weighings (SUM) averaged 48.6 g for common diving petrel chicks (n = 78 chick nights) and 41.6 g for South Georgia diving petrel chicks (n = 78 chick nights). Average adult feeding frequencies were 0.95 meals day−1 and 0.92 meals day−1, respectively. Relative meal size in diving petrels was similar to that of other procellariiforms, but SUM averaged about twice that of other petrels. The lower conversion efficiency of meals to body mass in diving petrel chicks reflects the absence of stomach oils in the diet. Higher chick feeding frequency and lower variance in SUM are consistent with the hypothesis that diving petrels forage nearshore on reliable food supply compared with other procellariiforms.

<p>W artykule dokonano analizy powstania rynku mediów w Gruzji – jednej z republik byłego Związku Radzieckiego. Dziś Gruzja jest jednym z wiodących krajów regionu Kaukazu, co potwierdzają różne oceny międzynarodowe. Gruzja zajmuje pierwsze miejsce w indeksie wolności mediów w regionie, co świadczy o demokratycznej transformacji kraju. W artykule przedstawiono ustawodawstwo krajowe regulujące mass media i analizujące kluczowe podmioty rynku medialnego. Opisując główne etapy procesu formowania gruzińskiego radia i telewizji, autorzy zwrócili uwagę na to, że niektóre media-gatunki, na przykład radiowe, były bardzo popularne we wszystkich przestrzeniach postsowieckich i za granicą. Współczesna Gruzja jest krajem o rozwiniętym rynku medialnym z wiodącymi graczami światowymi obecnymi we wszystkich segmentach mediów (telewizja, radio, prasa, telewizja kablowa, telewizja satelitarna, internet, blogosfera, niezależne studia telewizyjne). Ponadto obywatele Gruzji są aktywnymi użytkownikami internetu, mediów społecznościowych i blogów. Autorzy konkludują, że pomimo pewnych istniejących trudności i problemów gruzińskiego rynku mediów ma on dobre perspektywy rozwoju.</p>

Pollen morphology of six Verbascum (Scrophulariaceae) taxa belonging to five different groups in the genus [V. georgicum (group E), V. nudatum var. nudatum (group F), V. cariense (group F), V. bithynicum (group H), V. pycnostachyum (group K), and V. lasianthum (group L)] was studied. Pollen slides were prepared according to the Woodhouse method and were examined with light-microscopy (LM) and Scanning Electron Microscopy (SEM). All studied pollen grains are generally monads, though tetrads (5 %) were observed in Verbascum nudatum var. nudatum. Pollen grains of all studied taxa were determined as isopolar and radially symmetric. In general terms, aperture types are trizonocolporate, but also trisyncolpate (V. lasianthum 10 %, V. pycnostachum 1 %, and V. georgicum 4 %) and trizonocolpate (V. cariense 10 %, V. bithynicum 10%, V. lasianthum 90%, V. pycnostachyum 9%, and V. georgicum 96 %) aperture types were observed. The shapes of the pollen grains were determined as prolate, subprolate, prolate-spheroidal and oblate-spheroidal. The sculpture was reticulate in all cases. The results of the study corroborate that morphological features, such as pollen shape, polar axis length (P), equatorial axis length (L), aperture type, surface ornamentation, muri thickness, and lumina shape, show differences which can be taken into consideration in the systematic discrimination within the groups, and also for discrimination of the groups in the genus.

AbstractPseudochaenichthys georgianus is a member of the unique Channichthyidae family of fishes, which lack haemoglobin. The distribution, length-frequency and summer diet are described from 14 bottom trawl surveys undertaken in the summers between 1986 and 2006. Pseudochaenichthys georgianus (50–590 mm TL) were caught throughout the South Georgia shelf from depths of 76–370 m, but very few specimens (< 1%) were caught on the Shag Rocks shelf. Multiple cohorts were present during each survey and length-frequency analysis of these cohorts suggests that growth is fast during the first 3–4 years. Stomach contents analysis (2005 & 2006) indicated that P. georgianus is a pelagic or semi pelagic predator, with the summer diet dominated by Antarctic krill (Euphausia superba). Fish (channichthyids and notothenids) were also taken, but were a relatively minor part of the diet.

The paper presents an assessment of the prospects for the use of five species of the Pyrus L. genus: Pyrus communis L., P. caucasica Fed., P. georgica Kuth., P. vsevolodii Heideman, P. salicifolia Pall. in cultivation on the territory of the Greater Caucasus. These are the species that are most common in the north-eastern part of the Greater Caucasus (Azerbaijan). The evaluation of the studied species was carried out in terms of their viability in ex situ conditions. To assess the prospects for the introduction of trees and shrubs in ex situ conditions, the scale of E. O. Iskendarov was used. The work carried out made it possible to reveal that these plant species are divided into two groups under ex situ conditions. As a result, it was found that none of the species fell into the lower group. Group 1 of promising plants included 3 species (P. salicifolia Pall., P. georgica Kuth., P. vsevolodii Heideman). The other 2 species are assigned to the 2nd group of promising plants.

L'exploration de la niche écologique d'une espèce implique une analyse à plusieurs échelles, car différentes contraintes environnementales peuvent avoir des conséquences écologiques importantes. Cependant, l'absence d'informations précises sur l'écologie des petites espèces de procellariiformes a considérablement limité leur étude, impactant notre capacité à définir une planification de conservation appropriée. Les avancées technologiques dans la miniaturisation des enregistreurs de données permettent depuis peu de collecter des données écologiques sur ces espèces. Dans cette étude, une approche multidisciplinaire a été utilisée pour étudier la niche écologique des pétrels plongeurs communs et de Géorgie du Sud. Les principaux objectifs étaient de : 1) décrire leur écologie alimentaire pendant les périodes de reproduction et de non-reproduction, et étudier leurs variations interannuelles ; 2) déterminer les différences écologiques entre les populations de l'Océan Austral ; et 3) étudier les variations de leur écologie tout au long du cycle annuel dans un contexte de ségrégation écologique entre ces deux espèces sœurs. Les résultats ont démontré que les pétrels plongeurs présentent des capacités de vol remarquables malgré leur charge alaire élevée, se nourrissant sur de vastes zones pendant la reproduction et migrant à plusieurs milliers de kilomètres de leur colonie pendant la période post-reproduction. Ces analyses ont révélé d'importantes différences écologiques au sein des espèces, notamment en termes de phénologie et de zone de migration. La collecte de données sur plusieurs années a considérablement renforcé ces résultats et fournit des informations précieuses pour comprendre les limites des niches écologiques des pétrels plongeurs. Enfin, la variation de ségrégation en fonction du stade de reproduction a démontré l'importance d'une approche multi-outils pour mieux décrire et comprendre la coexistence d'espèces écologiquement similaires
Exploring a species’ ecological niche entails investigating at multiple scales, as different environmental threats and niche constraints between intra-species levels may lead to important ecological and conservation consequences. However, the absence of precise information about small procellariiform species ecology has greatly limited ecological niche modelling studies, directly impacting our ability to delineate proper conservation planning. Technological advancements in the miniaturisation of data loggers have made it possible to collect ecological data of such species. In the present study, a multi-tooled approach was used to investigate the ecological niche of the common and the South-Georgian diving petrels. The primary objectives were to: 1) describe their foraging ecology during the breeding and non-breeding periods, and investigate their inter-annual variations; 2) determine the ecological differences between populations throughout the Southern Ocean; and 3) study the variations in their foraging ecology throughout the entire annual-cycle in the context of niche segregation between two sibling species. The results demonstrated that diving petrels exhibit remarkable flying abilities despite their high wing loading, foraging over large areas during the breeding season, and migrating several thousands of kilometres from their colony during the post-breeding period. These analyses revealed important ecological differences throughout the species distribution, particularly in terms of phenology and migration area. Collecting data over several years substantially strengthens results and provides valuable information to understand the variations and the limits of diving petrel ecological niches. Finally, a stage-dependent and context-dependent niche segregation analysis demonstrated the importance of a multi-tooled approach to better describe and understand the co-existence of ecologically similar species

In a process that spanned over three years, Georgia adopted some important changes to its constitution that is meant to complete the country’s transition from a “semi-presidential to a parliamentary system of governance” (Civil.ge, 17 Dec. 2018). In the last 2020 parliamentary elections, Georgia’s current (revised) electoral mixed system was already the most proportional the country had seen in three decades (Bogishvili, 2020). 120 Members of Parliament (MPs) were elected proportionally by a party list (previously the number was 77) and the remaining 30 were single mandate (majoritarian) MPs elected by the ‘first-past-the-post’ rule (previous number was 73) (Bogishvili, 2020; OSCE, 2021, p.6). However, in the next parliamentary elections, due to take place in 2024, Georgia is meant to move to a fully proportional system (Civil.ge, 17 Dec. 2018). This rapid review explores some of the questions surrounding proportional representation in Georgia. In particular, what do these constitutional changes mean for Georgia? What might be some of the implications of Georgia’s move to proportional representation in 2024 and how might this affect governance? The report examines some of the main aspects of these constitutional changes during 2017-20 and puts them in context. It outlines some of the main discussions in Georgia concerning opportunities and challenges often associated with proportional representation and highlights some of the main points that emerge from these discussions on the future dynamics of governance in Georgia. Material summarised in this report is based on a mixture of (online) newspaper articles, government and other reports, and policy, and practitioner-based literature.
