Opis:
Morphological and molecular analyses of Battarrea phalloides from Macedonia were done. While B. phalloides specimens shown three kind of spore ornamentation, each one related to a clade in the phylogenetic ITS nrDNA tree; all specimens from Macedonia shown spores with anastomosing truncate ridges and very low variability of the ITS nrDNA sequences. The low genetic variability of these specimens, could be because of genetic drift.

Opis:
Current and historical occurrence as well as coenotic affinity and ecology of Carex secalina in the Czech Republic and Slovakia are presented. The study is based on revision of herbarium specimens from 25 herbaria, literature data excerption and a field survey carried out during 2004-2010. Altogether, 168 sites were documented in the Czech Republic divided to two separate areas. Stabile occurrence trend was found in last decades, because 45 localities were documented in period 1975-1999 (27% of sites) and recent occurrence was confirmed at 42 localities (24% of sites). On the basis of our current knowledge the species was included into the IUCN threat category VU (vulnerable). In Slovakia, 19 localities of the species were recorded in total, but only 4 sites were confirmed recently (21% of sites recorded). However, only a small number of individuals was recorded there (less than 50 individuals in total) and half of this sites is acutely threatened by destruction (ploughing, secondary succession). Therefore, the C. secalina status in the Slovak Red List was changed to the IUCN category “critically endangered” (CR). Results of the study are summarised in the maps of historical and current species distribution. C. secalina usually occurred in halophytic grassland communities, especially in association Agrostio stoloniferae-Juncetum ranarii Vicherek 1962. However, it may occur in many other communities which suggest that the species had not well-defined coenotic relationships. On the basis of our knowledge, we consider C. secalina as an obligate halophyte.

Opis:
The study presents recent data on the distribution of Fellhanera gyrophorica (Pilocarpaceae, Ascomycota) in Poland, a rare lichen with a crustose, usually sterile thallus. Both previous and new localities of the species are presented with data on its ecology and general distribution. Furthermore, this paper provides detailed results on floristic investigations of the species in the forest areas of the Pojezierze Olsztyńskie Lakeland (Northern Poland). Fertile specimens of F. gyrophorica have been observed in Poland for the second time and in the world – for the third time. Also, a new substrate for this species has been found: Acer platanoides. In addition, Carpinus betulus and Populus tremula were also found to be the species' substrates in Poland. Based on this study and previous reports, F. gyrophorica seems to be a relatively common species in north-eastern Poland.

Opis:
Micropaleontological investigation has been carried out, for the first time to study the systematic of recent Benthic Foraminifera from the southeast coast flowing river estuaries Cauvery, Athankarai and Thamirabarani, Tamil Nadu, India. Totally 16 sediment samples were collected during December 2018. Benthic foraminiferal species, belonging to 14 species, 7 families and 5 Sub-orders are identified. Among this Miliolida (>75%) occupies the dominant place followed by Rotaliida (<25%). The higher species are observed in the rivermouth area particularly in the Cauvery estuary sample (365 species of Ammonia beccarii). The following species are abundantly distributed in this region namely Ammonia beccarii, Quinqueloculina and Miliolinella subrotunda. The abundance of species in the river mouth may be due to the mixing of marine and nearshore environment.

Opis:
Dionysia involucrata Zaprjag. (Primulaceae) is known as critically endangered endemic species of Hissar Mountains in Tajikistan. It is reported from few localities mainly in Varzob River valley and its tributaries. The species inhabits steep or overhanging faces of granite rocks in narrow river gorges. During the research all known populations of D. involucrata were examined in respect of the habitat conditions and species composition of vegetation plots. We analyzed the population extent of the species in its range in Tajikistan and the main threats in order to assess its conservation status. The detrended correspondence analysis was performed on a matrix of 65 relevés and 49 species (vascular plants and mosses), to classify the phytocoenosis with domination of D. involucrata according to their floristic composition in relation to other petrophytic vegetation units. Using our field data regarding present extent of occurrence and area of occupancy we conclude that the threat category of D. involucrata should be reassessed from critically endangered to endangered. The species shows decline tendency in extent of occurrence, area of occupancy as well as in number of locations. The vegetation plots with domination of D. involucrata have relatively high level of separateness due to different species composition. We define the new association – Dionysietum involucratae – representing chasmophytic vegetation of submontane and montane zone in Middle Asia (ca. 1000–1600 m a.s.l.). The plots of Dionysietum involucratae were found mainly on granite rocks, on very steep or overhanging faces, on southwestern or southern exposition. The association is rather poor in species with inconsiderable contribution of mosses. Despite the diagnostic species, Campanula incanescens, Carex koshewnikowii and Scutellaria hissarica were the most abundant and frequent taxa within the researched patches of vegetation.

Opis:
The record of Hexagonarta in the Lower and Middle Devonian shows that only slow rates of change occurred at these times, whereas in Frasnian time there occurred complex diversity and speciation patterns. Very rapid faunal changes and mass extinctions in corals have been observed near the boundary of Middle Devonian and Upper Devonian and at the end of Fr 1 time. Based on the study of population variation, ecological variation and phylogenetic lineage, the complete evolutionary patterns of Hexagonaria can be traced in the Givetian and Frasnian. The evolutionary patterns observed in different facies demonstrate that: 1. most changes in diversity and speciation were strictly related to differences in the biology of species adapted to different or changing environments, 2. the critical factors in encouraging diversification of species appear to be a combination of ecologic conditions and paleogeographic situations, 3. some parallel evolutions were independent of environments and paleogeographic isolation but were due to time.

Opis:
Six well exposed mid−Ludlow stromatoporoid−dominated reef biostromes in four localities from the Hemse Group in southeastern Gotland, Sweden comprise a stromatoporoid assemblage dominated by four species; Clathrodictyon mohicanum, “Stromatopora” bekkeri, Plectostroma scaniense, and Lophiostroma schmidtii. All biostromes investigated in this area (of approximately 30 km²) are interpreted to belong to a single faunal assemblage forming a dense accumulation of fossils that is probably the best exposed stromatoporoid−rich deposit of the Silurian. The results from this comprehensive study strengthen earlier interpretations of a combination of genetic and environmental control on growth−forms of the stromatoporoids. Growth styles are similar for stromatoporoids in all six biostromes. Differences in biostrome fabric are due to variations in the degree of disturbance by storms. The uniformity of facies and the widespread low−diversity fauna support the view that palaeoenvironmental conditions were similar across the area where these biostromes crop out, and promoted the extraordinary growth of stromatoporoids in this shallow shelf area.

Opis:
Phylogenetic analyses place Octaviania asterosperma in the Boletales, with Leccinum being the closest relative. Results of the structural investigation of O. asterosperma ectomycorrhiza with Fagus confirm this systematic position. In Europe the species is an ectomycorrhizal partner of broad-leaved trees, such as Carpinus, Corylus, Fagus, Quercus and Tilia. This paper aims at presenting the new data to the distribution of O. asterosperma in Central Europe. The description of the basidiocarps discovered in Poland in the recent years is also given, together with evidence for the parasitic relationship of Sepedonium laevigatum with O. asterosperma. We also present the information concerning all known localities of the species in Poland and its distribution map. Data on the ecology, distribution and status of O. asterosperma in Europe, and some structural aspects of basidiocarps and spores, are also summarized.
Rosnące zainteresowanie grzybami podziemnymi sprawia, że odkrywane są nowe stanowiska dawno nie notowanych gatunków. Jednym z nich jest Octaviania asterosperma, podziemka gwiaździstozarodnikowa, należąca do podziemnych Basidiomycota. Wyniki analizy filogenetycznej, a także dane na temat mikoryzy Octaviania, stanowią argumenty za przynależnością rodzaju do rzędu Boletales. Niniejszy artykuł przedstawia dane na temat nowych oraz znanych z literatury stanowisk O. asterosperma wraz z mapą rozmieszczenia gatunku w Polsce. Prezentuje także opis owocników odnalezionych w ostatnich latach w południowej i środkowej części naszego kraju oraz wyniki obserwacji pasożytowania Sepedonium laevigatum na owocnikach podziemki gwiaździstozarodnikowej. W artykule podsumowane są również informacje na temat ekologii, rozmieszczenia i statusu gatunku w Europie, a także dane o strukturze i rozwoju owocników oraz zarodników Octaviania asterosperma.

Opis:
The objective of the paper was to know preferences of consumers from Małopolskie Voivodeship as a fundamental factor of growth and functioning of distribution channels of organic products. A fast development of the organic products market as well as growing requirements of the society with regard to the quality of sale and form are observed. More and more often consumers pay attention to the source of goods and the form in which the product is offered to them. Research and analyses are a precious source of information for agricultural producers on account of production orientation and the form of sale. It will also facilitate development of existing distribution channels and formation of new ones. Research results indicate that consumers are interested in the purchase of products in small packaging or loose. Sums which they spend on organic food do not exceed PLN 400 per a month.
Celem pracy było poznanie preferencji konsumentów z terenu województwa małopolskiego jako podstawowego czynnika rozwoju i funkcjonowania kanałów dystrybucji produktów ekologicznych. Obserwujemy szybki rozwój rynku produktów ekologicznych, jak też rosnące wymagania społeczeństwa co do jakości i formy sprzedaży. Coraz częściej konsumenci zwracają uwagę na źródło pochodzenia towaru oraz postać w jaki produkt jest im proponowany. Prowadzenie takich badań i analiz jest cennym źródłem informacji dla producentów rolnych pod kątem ukierunkowania produkcji oraz doboru odpowiednich form sprzedaży. Ułatwi to również rozwój istniejących już kanałów dystrybucji oraz łatwiejsze tworzenie nowych. Wyniki badań wskazują na fakt, że konsumenci zainteresowani są zakupem produktów w małych opakowaniach lub luzem, a kwoty jakie wydają na produkty ekologiczne nie przekraczają 400 PLN w skali miesiąca.
