<em>Pilularia globulifera </em>is a subatlantic European fern threatened with extinction. In Poland, it reaches the eastern border of its continuous range. Up to the end of the 20th century, it was observed here in 21 stands; only 2 of them existed by the second half of the century, so the species was categorized as critically endangered. Five new locations have been found in western and northwestern Poland during the last 10 years. Abundant and permanent populations grow in 3 locations, while 2 stands were ephemeral. All the current stands are situated in anthropogenic habitats with spontaneous vegetation, in oligotrophic to eutrophic waters. One of the new localities is about 280 km distant from the eastern range of the limit known previously. <em>Pilularia </em>forms its own plant community <em>Pilularietum globuliferae</em>, enters plots of <em>Ranunculo-Juncetum bulbosi </em>and occurs in mesotrophic to eutrophic rushes of <em>Eleocharis palustris</em>, <em>Phragmites australis</em>, <em>Typha angustifolia </em>and <em>Equisetum fluviatile</em>. Specimens are vigorous and regularly produce sporocarps.

ABSTRACTHabitat loss and alteration is widely considered one of the main drivers of the current loss of pollinator diversity. Unfortunately, we still lack a comprehensive analysis of habitat importance, use and preference for major groups of pollinators. Here, we address this gap analysing a large dataset of 15,762 bee specimens (more than 400 species) across northeast USA. We found that natural habitats sustain the highest bee diversity, with many species strongly depending on such habitats. By characterizing habitat use and preference for the 45 most abundant species, we also show that many bee species can use human-altered habitats despite exhibiting strong and clear preferences for forested habitats. However, only a few species appear to do well when the habitat has been drastically modified. We conclude that although altered environments may harbor a substantial number of species, preserving natural areas is still essential to guarantee the conservation of bee biodiversity.

Abstract The genus Aneura is represented in Poland by two species - A. pinguis and A. maxima. A. pinguis in contrast to A. maxima is a complex of cryptic species temporarily named A. pinguis species: A, B, C, and E. All species of the A. pinguis complex and A. maxima differ in their geographic distribution and habitat preferences. A. pinguis species A grows mainly on humus over limestone rocks in the Western Carpathians, A. pinguis species B occurs mainly on clay soil in Bieszczady Mts. and in clayish areas of lowlands, A. pinguis species C grows both in lowlands and mountains and it occupies mostly wet sandy soils, on the shores of oligotrophic lakes and river and mountain stream banks, A. pinguis species E is connected with calcareous rocks in flowing water in mountains. A. maxima grows over the country - both in lowlands and mountains, in marshes situated on the river banks.

Various types of forest and meadow plant communities of the Kabardino-Balkar Republic (CentralCaucasus) from the steppes to the alpine were examined by the route method during floristic investigations in 2018–2019. New locations of five rare species of vascular plants of the region natural flora were found (Picea orientalis (L.)Peterm., Taxus baccata L., Betula raddeana Trautv., Acer trautvetteri Medw., Eriophorum angustifolium Honck.). Exactlocations for another five rare species within the previously designated areas were also identified (Pojarkovia pojarkovae(Schischk.) Greuter., Scopolia carniolica Jacq., Hypericum nummularioides Trautv., Securigera orientalis(Mill.) Lassen,Galanthus alpinus Sosn.). The article presents the data on the floristic finds, indicating the coordinates of specific locations,species habitat preferences in region, the number of populations, the species distribution in the Caucasus, and informationof inclusion in the Red Books of adjacent regions. The rarest vascular plant species for the native flora of the KabardinoBalkar Republic are Galanthus alpinus, Scopolia carniolica, Pojarkovia pojarkovae. All three species were revealed inmountain territories subject to high recreational (trampling by tourists, picking up flowers) and economic (grazing) loads.All three species were revealed in mountain territories. The findings of isolated populations of Picea orientalis, Taxus baccata, Betula raddeana, Acer trautvetteri provided new information about the distribution and ecology of these rarespecies listed in the latest edition of regional Red Data Book. For these species, the categories of rarity status acceptedin the Red Book of the Kabardino-Balkar Republic are confirmed. Galanthus alpinus, Scopolia carniolica, Pojarkoviapojarkovae, Hypericum nummularioides, Securigera orientalis, Eriophorum angustifolium are proposed for inclusion inthe next edition of the Kabardino-Balkar Red Data Book. The most endangered state was identified for Picea orientalis,for which only two habitats in the region are reliably known and those are subject to intense anthropogenic impact.

The Polish localities of <i>Orobanche ramosa</i> L., branched broomrape, are either extinct or have not been confirmed for many years. This paper presents two new localities of <i>O. ramosa</i> in Poland from the Płaskowyż Proszowicki plateau (Wyżyna Małopolska upland) and the Nizina Nadwiślańska lowland (Kotlina Sandomierska basin). Habitat preferences and the abundance at the sites are described. A revised map of the distribution and a historical analysis of preferred hosts in Poland are included. The taxonomy, biology, ecology and control methods of <i>O. ramosa</i> are also discussed.

The article presents information on floristic findings in the Kabardino-Balkari Republic. As a result of expedition research in 2020-2021 and inventory studies in the Herbarium of the Tembotov Institute of Ecology of Mountain Territories RAS, we revealed nine species new to the Kabardino-Balkar Republic and new locations of ten vascular plants species. Species new to the region flora were Carex acuta, Genista angustifolia, Amorpha fruticosa, Ambrosia psilostachya, Mercurialis annua, Echinocystis lobata, Phlomis majkopensis, Cleistogenes squarrosa, Bidens frondosa. New locations of seven species were identified for the Balkarskiy floristic region. These were three native species (Carex flacca subsp. erythrostachys, C. songorica, Eriophorum latifolium) and four alien species (Oenothera biennis, Elsholtzia ciliata, Sigesbeckia orientalis, Bidens frondosa). Carex elongata, Genista angustifolia, Ambrosia psilostachya, Mercurialis annua, Cleistogenes squarrosa, Amaranthus albus and alien species Acer negundo were revealed for the Tsentralno-Elbrusskiy and Kabardinskiy floristic regions, respectively. We also found the alien species Amorpha fruticosa, Echinocystis lobata and rare steppe species Phlomis majkopensis, Glaucium corniculatum in the Tursko-Sunzhensky floristic region. We provided data on floristic findings indicating the coordinates of the locations, species habitat preferences, and distribution in the Caucasus according to earlier literary sources.

Iris spuria L. was found at two new locations in the Vojvodina Province in 1997, both of them in the vicinity of Sombor: near the village of Krusevlje (CR59 according to 10x10 km UTM grid) and near the village of Backi Monostor in the Kozara Forest (CR47 according to 10x10 km UTM grid). Patches of the plants were sketched and observed until 2001. The populations in both locations had been stable, though under possible influence of humans (picking, burning) and animals: bloom-eater (Trapinota hirta), and wild pigs (Sus scrofa). Fencing off stand with Iris spuria L. population in the Kozara Forest is recommended.
