Recent studies suggest that horizontal gene transfer (HGT) played a significant role in the evolution of eukaryotic lineages. We here review the mechanisms of HGT in plants and the importance of HGT in land plant evolution. In particular, we discuss the role of HGT in plant colonization of land, phototropic response, C4 photosynthesis, and mitochondrial genome evolution.
The Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) is now available. It provides policymakers with an assessment of information on climate change, its impacts and possible response options (adaptation and mitigation). Summaries for policymakers of three reports of IPCC working groups and of the Synthesis Report have now been approved by IPCC plenaries. This present...
It is frequently mentioned that during economic crisis one of the key elements of strengthening SMEs is permanent renewal and capability of innovation. However, only some businesses are able to carry out classical product/service innovation (Schumpeter). We are of the opinion that observing the best practice, adoption and/or adaption – the imitation – should be given a higher function in everyday...
The paper presents the process of cross-compliance implementation in Poland. The definition of the process as well as its components are discussed with the use of an example of the cross-compliance mechanism. This mechanism is shown at the macroeconomic level (country level) and the microeconomic level (on a farm), as well as the role of FAS bodies in the process of farm adaptation. Empirical studies...
The presence of ruderal and mid-field vegetation promotes conservation of biodiversity and provides an additional source of food for insect pollinators. The white deadnettle is a common synanthropic plant visited frequently by various groups of insects, as it is a source of pollen and nectar. In 2012–2013, in the city of Lublin (Poland), signalling and food attractants in L. album flowers were analysed...
Thanks to precision farming technology, farmers are able to optimise input in the field with management-zones. Management-zones (the smallest treatment unit in the field) are defined on the basis of knowledge of local conditions, e.g. physical and chemical soil conditions, soil productivity, the presence of weeds and/or pests as well as the incidence of disease. Precision farming technology is able...
Today no country in the world can hope for achieving a sustainable competitiveness of the national economic complex and, consequently, for its bright future, without its successful adaptation to the market management conditions. The article deals with the problems of a respective agrarian sector adaptation.
Seasonal changes in the morphometric and physiological parameters of the cockle Cerastoderma glaucum (Bivalvia) from the Baltic Sea (GD), the North Sea (LV), and the Mediterranean Sea (BL) were investigated. The cockles from GD were much smaller than those from other populations due to osmotic stress. The female to male ratios did not differ significantly from 1 : 1. The northern populations (GD,...
Two provenance experiments with Norway spruce in Slovakia were used to reveal trends in the behaviour of provenances after their transfer. Regressions between the average height and survival of provenances and the differences between the geographic and selected climatic characteristics of the place of origin and provenance plots were significant for most of the characteristics tested. Data from the...
