The work presents information about the range, occurrence conditions, geographical and historical status and dynamic tendencies of Melilotus wolgica in Eurasia and Poland. In Poland, the species was noted for the first time in Szczecin at the end of 19th century. Later, it was observed in the anthropogenic localities in the Opole Province, Kraków and Warszawa. In Wielkopolska, M. wolgica was observed...
This paper presents new distribution stands for 70 species of lichenized town from Łomża town (Podlasie, NE Poland). The investigations in the area of Łomża were carried out in the years 2014–2015, on 34 research stands. Seven species have been put on the Red list of the lichens in Poland (Cieśliński et al. 2006), including Rhizocarpon lavatum in critically endangered – CR, Ramalina fastigiata, R...
The object of analysis is a heat conduction problem within the frames of tolerance modelling in multicomponent, multilayered composites with functional gradation of effective material properties. The equations of proposed model for considered composites are partial differential equations with slowly-varying coefficients. The one-dimensional, stationary problem of heat conduction in direction perpendicular...
The distribution of nematodes was studied in rice fields in Guilan province, Iran, from 2014 to 2016. Nematode biodiversity of 250 soil and root samples was examined. Thirty nematode species were identified morphologically, including plant parasites, microbivores and mycetophagous and predator species. Molecular techniques were also used for further identification of three plant parasitic species...
Rhynchosporium commune (formerly known as Rhynchosporium secalis), the causal agent of scald disease on barley, is known to spread asexually by splash dispersed conidia. However, there are multiple lines of evidence for the possibility of a clandestine sexual cycle occurrence in this species including extensive genotypic diversity, equal distribution of mating type alleles across the world and expression...
In this paper the problem of non-parametric estimation of the probability density function for hydrological data is considered. For a given random sample X1, X2, ..., Xn we define an estimator fˆn of the density function ƒ based on a function K of a real variable – the so-called kernel of a distribution – and a properly chosen number sequence {hn} from the interval (0, ∞). This estimator of density...
Two parasitoid wasps, Torymus artemisiae Mayr and Torymoides violaceus (Nikol’skaya), were reared on Artemisia herba-alba (Asteraceae) galles, in central Iran. Torymus artemisiae and T. violaceus were developed from the gall midges: Rhopalomyia navasi Tavares and R. hispanica Tavares, respectively. The occurrence of these two parasitic wasps in Iran, and their associations with R. navasi and R. hispanica,...
New localities of Arnoseris minima (L.) Schweigger et Koerte (Asteraceae) in the Podlasie region (NE Poland) are presented. The current distribution of the species was established on the basis of the authors’ floristic field studies, revised herbarium materials, published data, and unpublished sources. The collected data enabled us to revise the map of the species’ distribution in the Podlasie region...
The paper reports new localities of lichens Parmelia ernstiae and P. serrana in Poland. Both species are reported for the first time from the Polish part of the Sudety Mountains (southwestern part of the country). The new localities were found in the area of the Sowie Mountains (central part of the Sudety Mts) as well as Śnieżnik Massif and Bialskie Mountains (eastern part of the Sudety Mts). Most...
The paper presents models of potential geographical distribution of Xanthoparmelia delisei, X. loxodes, and X. verrucu-lifera in Central Europe. The models were developed with MaxEnt (maximum entropy algorithm) based on 224 collection localities and bioclimatic variables. The applied method enabled to identify the areas where climatic conditions are the most suitable for modeled species outside their...
A paper presents a list of 89 species found in Supraśl town (Podlasie, NE Poland). The investigations in the area of Supraśl were carried out in 2013–2014, on 41 research stands. Eighteen species are considered to be threatened in Poland. The lichens occur on all substrate types: soil, decaying wood, bark of all trees and shrubs species, boulders, concrete, foundation, mortar, plaster and bryophytes...
Knowledge of a species’ distribution and habitat preferences is of paramount importance when assessing its conservation status. We used accurately recorded occurrence records and ecological niche modeling to predict the distribution of two poorly known small carnivore species that occur in Asia, the spotted linsang (Prionodon pardicolor) and banded linsang (Prionodon linsang), and analyzed their niche...
