Energy crops affecting farmland birds in Central Europe: insights from a miscanthus-dominated landscape.

Biologia (Bratisl) 2019 5;74(1):35-44. Epub 2018 Nov 5.

Institute of Zoology, Poznań University of Life Sciences, Wojska Polskiego 71C, 60-625 Poznań, Poland.

The expansion of energy crops such as miscanthus has changed the habitat of European farmland birds. However, most studies on the subject are based in Western Europe. We surveyed the avian community in a sample bioenergy landscape in Poland to investigate the pattern of use of the crop by birds in Central Europe. Read More

Impact of troublesome expansive weed on species diversity of mountain pastures in Tatra National Park, Poland.

Biologia (Bratisl) 2019 11;74(1):15-24. Epub 2018 Dec 11.

2Faculty of Biology and Environmental Sciences, Cardinal Stefan Wyszyński University in Warsaw, Wóycickiego 1/3, 01-938 Warszawa, Poland.

Alpine dock () is a native plant species in many European mountain ranges. It comes from moist brushwood and open tall herb communities, though it has invaded mountain pastures. This troublesome weed forms permanent monodominant stands characterised by low nature conservation and agricultural values. Read More

Influence of short periods of increased water temperature on species composition and photosynthetic activity in the Baltic periphyton communities.

Biologia (Bratisl) 2018 13;73(11):1067-1072. Epub 2018 Sep 13.

Institute of Oceanography, University of Gdańsk, Al. Piłsudskiego 46, 81-378 Gdynia, Poland.

Periphyton plays a vital ecological role in shallow, well-lit ecosystems which are vulnerable to rapidly changing environmental conditions, including raising temperature due to global warming. Nevertheless, little is known on the effect of increased temperatures on the taxonomic structure and functioning of periphytic communities. In this study, the influence of short-term temperature increase on the species composition and photosynthetic activity of the Baltic periphytic communities was investigated. Read More

Uptake and reaction to roundup ultra 360 SL in soybean seedlings.

Biologia (Bratisl) 2018 6;73(7):637-646. Epub 2018 Aug 6.

2Department of Environmental Toxicology, Faculty of Environmental Management and Agriculture, University of Warmia and Mazury in Olsztyn, Prawocheńskiego 17, 10-720 Olsztyn, Poland.

Due to the widespread and frequent use of Roundup Ultra 360 SL in crops production, the active substance glyphosate is often present (in the soil or in post-harvest remnants) and may be toxic to plants, including the non-target species. The aim of the current study was to determine the sensitivity of young soybean seedlings to glyphosate in concentrations ranging from 0 to 10 μM. It was demonstrated that the seedlings take small quantities of soil glyphosate up. Read More

Activity of beavers as an ecological factor that affects the benthos of small rivers - a case study in the Żylica River (Poland).

Biologia (Bratisl) 2018 11;73(6):577-588. Epub 2018 Jun 11.

Department of Hydrobiology, Faculty of Biology and Environmental Protection, University of Silesia, Bankowa 9, 40-007 Katowice, Poland.

The Eurasian beaver () has a greater impact on local ecosystems than other herbivores, and the affected area exceeds the range of its presence. Its activity may change or create new habitats by modifying the availability of the biotic and abiotic resources available not only to beavers, but also to other groups of animals. Our aim was to study how beaver activity affects the benthos composition in a small river and in a beaver pond. Read More

Lymphatic drainage of cerebrospinal fluid in mammals - are arachnoid granulations the main route of cerebrospinal fluid outflow?

Biologia (Bratisl) 2018 27;73(6):563-568. Epub 2018 Jun 27.

Faculty of Veterinary Medicine, Department of Surgery, Wroclaw University of Environmental and Life Sciences, Pl. Grunwaldzki 51, 50-366 Wroclaw, Poland.

The outflow of the cerebrospinal fluid (CSF) in animals was over the years the subject of detailed analysis. For a long time it was stated that arachnoid granulations of the venous sinuses play a key role in CSF circulation. However, recent studies on this subject have shown that a considerable part of the CSF is drained to the lymphatic vessels. Read More

Impact of windstorm on a community of centipedes (Chilopoda) in a beech forest in Western Poland.

Biologia (Bratisl) 2018 26;73(2):165-173. Epub 2018 Mar 26.

Department of General Zoology, Adam Mickiewicz University, Umultowska 89, 61614 Poznań, Poland.

The study was carried out in the years 2016-2017, five years after a windstorm which destroyed 1/3 of the protected beech forest area in the west of Poland. The community of centipedes in the area affected by the windstorm was depleted in terms of the species richness, diversity, and population density. The dominance structures were shortened and the species composition was rebuilt. Read More

Resonance of about-weekly human heart rate rhythm with solar activity change.

Biologia (Bratisl) 1996 Dec;51(6):749-56

University of Minnesota, Lyon Laboratories, Minneapolis 55455, USA.

In several human adults, certain solar activity rhythms may influence an about 7-day rhythm in heart rate. When no about-weekly feature was found in the rate of change in sunspot area, a measure of solar activity, the double amplitude of a circadian heart rate rhythm, approximated by the fit of a 7-day cosine curve, was lower, as was heart rate corresponds to about-weekly features in solar activity and/or relates to a sunspot cycle.
