Spotted souslik is one of the most endangered mammal species in Poland. Over the last few decades of the 20th century its population gradually decreased due to the influence of natural and anthropogenic factors: degradation of species habitats and reduction of their acreage. The aim of the study is to examine changes in the population of spotted souslik in eastern Poland, against threats to the species...
This paper presents the distribution of Pedicularis sylvatica, an endangered species across the whole Poland. In order to illustrate its dynamics four time periods were taken into consideration: before 1900, 1901-1950, 1951-1990 and after 1990. Until the present, 599 localities of P. sylvatica, have been known, half of which, i.e. 276 were recorded during intensive studies on wetland habitats in the...
As a result of the faunistic studies conducted in 2014-2015 in eight promotional forest complexes in Poland, 14 species of saproxylic beetles were recorded, representing 10 families. The presence of new localities for saproxylic beetles, i.e. Evodinellus borealis (Gyll.) (Cerambycidae), Pediacus dermestoides (F.) (Cucujidae), Triplax scutellaris Charp. (Erotylidae), Benibotarus taygetanus (Pic) (Lycidae)...
Thirty-nine weevil species are listed from the Świętokrzyskie Mountains for the first time, raising the total number of Curculionoidea (except Scolytinae) known to occur in this region of Poland to 438. New records concern species from the families Anthribidae (1), Apionidae (4) and Curculionidae (34). Several species are commented upon, providing also a critical discussion on host associations of...
A rare and protected species of the sedge Carex secalina was recorded in Dulsk near Inowrocław (Kujawy-Pomerania Province) in June 2014. It occupied the shores of ephemeral midfield water reservoirs in the complex of intensively used crop fields. Two subpopulations of this sedge with 36 tussocks in total were found. In the first subpopulation, the tussock diameter reached up to 25 cm, with 12–16 generative...
We provide information about two species, Pilosella bauhinii and P. cymosa subsp. vaillantii (Asteraceae), from new localities in north-central Poland (ATPOL DC18). All individuals of both species grew on a railway embankment in Górzno-Lidzbark Landscape Park. The ecological preferences for P. cymosa and P. bauhinii estimated according to average Ellenberg values nearly coincided with the original...
This paper presents the macromorphological and micromorphological characteristics of wood barley recorded in the Wielkopolska Lowland. On the basis of the collection of preserved specimens, the micromorphological features were examined under a scanning electron microscope (SEM) to assess their taxonomic value. The principal features include the size and shape of cork/silica cells, crown cells, prickles,...
