Activity of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services for biodiversity conservation
(2017)W artykule przedstawiono zwięzłe sprawozdanie dotyczące chronologii oraz działalności Międzyrządowej Platformy Polityki Naukowej w sprawie Różnorodności Biologicznej i Usług Ekosystemowych (IPBES). Organizacja ta przywiązuje ... -
Wild bee decline and conservation in North America
(2017)Pszczoły - to niezwykle różnorodna i ważna grupa owadów; około 4600 gatunków pszczół występuje w Ameryce Północnej. Dzikie pszczoły „świadczą usługi” w zakresie zapylania roślin, a ich działalność jest prawdopodobnie ... -
Skin ectoparasites of domestic animals
(2017)Zwierzęta towarzyszące ludziom, w tym zwierzęta domowe odgrywają ważną rolę w otaczającym nas środowisku. Jednak większość z nich może być narażona na kontakt z gatunkami pasożytniczych roztoczy i owadów, o dużym znaczeniu ... -
Allelopathic activity of the Baltic picocyanobacterium Synechocystis sp.
(2017)Allelopathic compounds produced by picocyanobacteria could affect the growth and development of biological systems. The main aim of this study was to investigate the influence of unknown allelochemicals obtained from ... -
Allelopathic effect of the Baltic picocyanobacterium Synechococcus sp. on selected diatoms
(2017)It is commonly believed that the structure of phytoplankton and the formation of cyanobacterial and algal blooms may be explained by allelopathic interactions. The main aim of this study was to investigate the ... -
A record of Silene viscaria (L.) Jess. (Caryophyllaceae) with achromatic flowers in the Mordovia State Nature Reserve (Central Russia)
(2017)Silene viscaria (L.) Jess. is a common species of Central Russian flora. It has attractive purple, crimson, or dark-pink inflorescences. Some literature sources indicate the possibility of white-colour flowers. However, there ... -
The yield of Jerusalem artichoke plant Helianthus tuberosus L. grown in various combinations of fertilisation – preliminary research
(2017)Jerusalem artichoke is a perennial plant, which originates from North America. Tubers are characterised by high nutritional and energy values and can therefore be a source of food for humans and animals. The interest in ... -
The influence of foliar “feeding” of urea on yield and its components of Iranian hybrid rice Oryza sativa L. ‘Bahar 1’
(2017)Because of waterlogged conditions in rice cultivation, much of the surface-broadcasted urea dissolves in paddy water and is unreachable to the rice crop for this reason. A field experiment was conducted to estimate the ... -
The photosynthetic activity of Paramecium bursaria endosymbiotic algae in varying temperature conditions
(2017)The aim of this study was to investigate the effect of higher temperatures on the photosynthesis of endosymbiotic Chlorella sp. of two Paramecium bursaria Ehrenberg 1831 strains originating from regions with a warmer and ... -
The impact of temperature and photosynthetically active radiation on the growth and pigments concentration in Baltic picocyanobacterium Synechococcus sp.
(2017)The experiments on three Baltic picocyanobacterial strains of Synechococcus (BA-120 – red strain, BA-124 – green strain and BA-132 – brown strain) were conducted at four scalar irradiances in Photosynthetically Active ... -
Spiders (Araneae) of the abandoned pasture near the village of Malé Kršteňany (Western Slovakia)
(2017)Abandoned pastures are frequent phenomenon throughout central Europe due to the reduction of grazing. This also concerns the abandoned pasture near the village of Malé Krštenany (Western Slovakia). We dealt with the ... -
Composition of phytoplankton in the Puck Bay and the open Baltic Sea
(2017)The Puck Bay is an area characterised by specific hydrodynamic conditions that determine the distribution and composition of phytoplankton. The aim of this study was to investigate the differences in the phytoplankton ... -
The succession of abandoned glades and its impact on the diversity of flora in Beskid Mały Mountains (Southern Poland)
(2017)The influence of grazing, mowing, and other usable treatments on the flora diversity of glades in the Beskid Mały in southern Poland was investigated. The field research was carried out between 2015 and 2016. Flora analysis ...
