AbstractThe paper deals with bryophytes collected by Polish researchers from the mires in the eastern part of Lithuania in 1934–1940 and deposited at the Herbarium of W. Szafer Institute of Botany, Polish Academy of Sciences (KRAM). The collection provides data on bryophyte diversity and distribution patterns in the mires of Lithuania. The collection (868 specimens) was revised in 2016–2017. Almost 90% of all herbarium specimens were collected by Irena Dąbkowska. The specimens were identified by the collectors themselves or by Polish bryologist Zygmunt Czubiński; 254 specimens of the collection were not identified. After revision, a total of 112 bryophyte species were ascertained in the collection, two of these (Palustriella decipiens and Polytrichum swartzii) have not been reported to Lithuania before. The specimens were collected in 47 localities, the mires in nearly half of them at the moment are disturbed due to drainage or use for peat extraction. Information about the localities of rare species Hamatocaulis vernicosus, Meesia triquetra and Mesoptychia rutheana is valuable for the estimation of their population status.

Abstract Assessing distribution patterns of valuable taxa plays an important role in the biodiversity conservation of these taxa. The genus Crocus L. (Iridaceae) comprises about 100 species that are distributed mainly in the Mediterranean region and western Asia. The present study purposed to assess the distribution patterns of Iranian Crocus species (including C. sativus L. and 8 wild species) and their conservation status in Iran as one of diversity centers of Crocus in the Middle East. A set of geographic distribution data was compiled through field studies, and reviews of herbarium specimens, iNaturalist, and various Flora. Localities were marked on geo-referenced maps (1/106) of Iran using ArcView version 3.2 (Esri, 2000). The distribution patterns of the taxa were mapped per 0.25° × 0.25° universal transverse Mercator grid cells (25 km2 with the exception of boundary area). Based on the species distribution (SDI) (33%) and species specialization (SSI) (44%) indices, those Iranian Crocus species that are threatened are mainly distributed in Irano-Turanian region. The mountainous ecosystems of Almeh and Western Alborz are important distribution centers of these taxa. Iranian Crocus species with SSI < 0.5 (C. almehensis, C. gilanicus, C. michelsonii, and C. caspius) have the highest conservation value.

Indobanalia thyrsiflora is an endemic species occurring in peninsular India (Andhra Pradesh, Karnataka, Kerala and Tamil Nadu States) and Sri Lanka. A nomenclatural study of the basionym Banalia thyrsiflora, published by Moquin-Tandon in Candolle’s Prodromus (year 1849), is carried out and the name is lectotypified on a specimen deposited at P (barcode P00609924); isolectotypes are traced at K and CAL. A preliminary morphological characterization of the species is also given, based on field surveys and examination of herbarium specimens. We noted that I. thyrsiflora is highly variable. However, we prefer to avoid, for the moment, taxonomic conclusions about the various morphotypes found, waiting the complete results of this ongoing morphological and molecular investigations.

AbstractWe explore the environmental status of three low surface brightness dwarf spheroidal galaxies (dSphs) KKH65, KK180 and KK227 using the results of our long slit spectroscopic observations at the 6m telescope of the Russian Academy of Sciences and surface photometry on the Sloan Digital Sky Survey (SDSS) images. The objects were selected by Karachentseva in 2010 as presumably isolated galaxies. The obtained surface brightness profiles demonstrate that our sample dSphs are less centrally concentrated than the objects of the same morphological type in the Virgo cluster (VC). Using the derived kinematic data we searched for possible neighbours of the dSphs within the projected distances from them Rproj > 500 kpc and with the differences in radial velocities |Δ V| > 500 kms−1. We applied the group finding algorithm by Makarov and Karachentsev to the selected sample. Our analysis shows that the dwarf galaxies of our study are not isolated. KKH65 and KK227 belong to the groups NGC3414 and NGC5371, respectively. KK180 is in the VC infall region. We conclude that it is not possible at the moment to justify the existence of isolated dSphs outside the Local Volume. The searches are complicated due to the lack of the accurate distances to the galaxies farther than 10 Mpc.

The article is devoted to the analysis of the role that environmental education and upbringing play in the formation of eco-friendly awareness and thinking. The author outlines that at the moment, it is becoming clear that it is impossible to overcome the ecological crisis exclusively by technical means. It is also noted that the creation of a system of environmental education and upbringing is one of the most important ways to overcome the environmental crisis. The result of the work of such a system should be the formation of a developed eco-friendly awareness among all age and social groups. Theoretical bases. The features of environmentalism and the principles of eco-friendly awareness formulated by N.F. Reimers are reviewed; the main requirements for modern environmental education are analyzed. Special attention is paid to ecological culture in the philosophy of ecology. The scientific and educational projects in the field of ecology aimed at the exchange of experience and practical skills between the older and younger generations are described. As part of the course "History and philosophy of science" at the Institute of philosophy of the Russian Academy of Sciences, postgraduate students of biological specialties are taught a course on the basics of bio-and ecophilosophy to develop a holistic worldview in the field of science under study. It is concluded that environmental education contributes to the development of eco-friendly awareness, ecological culture and eco-friendly thinking, which is the most important condition for overcoming the environmental crisis and the harmonious coexistence of humanity and nature.

Initial Results

&lt;p&gt;Sedimentary ancient DNA has by now become a recognized source of information on past biodiversity change, but our understanding of its dynamics and taphonomy is still limited. While for environmental DNA in water, dedicated investigations on its provenance and degradation are being increasingly carried out, we know very little about sedimentary DNA, in particular with respect to aquatic organisms. We are therefore conducting investigations on the distribution of DNA in surface sediments and a short sediment core, with a focus on aquatic communities in the large and heterogeneous Lake Constance. Targeted organisms range from phyto- and zooplankton to fish and waterbirds. Initial results and comparison with sightings of rare species indicate that the DNA is not distributed uniformly or widely across the lake, especially for multicellular animals, but rather linked to the local presence of the organisms. This has implications for our understanding of how DNA enters the sediment and for paleoecological inferences derived from these records.&lt;/p&gt;
