Retrotransposon-based genetic diversity of Deschampsia antarctica Desv. from King George Island (Maritime Antarctic)

Piotr Androsiuk, Katarzyna J. Chwedorzewska, Justyna Dulska, Sylwia Milarska & Irena Giełwanowska
Deschampsia antarctica Desv. can be found in diverse Antarctic habitats which may vary considerably in terms of environmental conditions and soil properties. As a result, the species is characterized by wide ecotypic variation in terms of both morphological and anatomical traits. The species is a unique example of an organism that can successfully colonize inhospitable regions due to its phenomenal ability to adapt to both the local mosaic of microhabitats and to general climatic fluctuations....

In the present study, agricultural biomass; palm kernel shell (PKS) and coconut shell (CS) were used to produce high porosity bioadsorbent using two-stage continuous physical activation method with different gas carrier (air and N2) in each stage. The activation temperature was set constant at 600°C, 700°C, 800°C or 900°C for both activation stages with the heating rate of 3°C min-1. Two parameters including the gas carrier and activation temperature were determined as the significant factors...

Nest-boxes alter the reproductive ecology of urban cavity-nesters in a species-dependent way

Joanna Sudyka, Irene Di Lecce, Lucyna Wojas, Patryk Rowiński & Marta Szulkin
Human-provided nesting shelters such as nest-boxes mitigate the shortage of natural breeding sites. Since artificial nests are not where animals evolved and optimised their reproductive performance, it remains inconclusive if these are adequate substitutes, ensuring equivalent fitness returns while breeding. In particular, most knowledge on the ecology of cavity-nesting birds comes from nest-box populations, but no study has directly compared fitness consequences of breeding inside nest-boxes in relation to natural cavities in cities. We directly...

Seniorzy w Polsce – stan zdrowia, wsparcie instytucjonalne i opieka nieformalna

Małgorzata Helena Herudzińska
W Polsce (choć nie tylko) ostatnie dziesięciolecia cechuje trwałe zjawisko, jakim jest wzrost udziału osób starszych w strukturze wieku ludności. Dynamika zmian społecznych, których źródłem są m.in. procesy demograficzne powoduje, że jednym z ważniejszych dziś wyzwań jest kwestia opieki nad seniorami. W naszym kraju opieka ta organizowana jest głównie w sferze prywatnej – ogromną rolę odgrywa tutaj rodzina. Tymczasem jej opiekuńczy potencjał maleje.

Antitumor activity of the protein kinase inhibitor 1-(β-D-2′-deoxyribofuranosyl)-4,5,6,7-tetrabromo- 1H-benzimidazole in breast cancer cell lines

Mirosława Koronkiewicz, Zygmunt Kazimierczuk & Andrzej Orzeszko
Abstract Background The protein kinases CK2 and PIM-1 are involved in cell proliferation and survival, the cell cycle, and drug resistance, and they are found overexpressed in virtually all types of human cancer, including breast cancer. In this study, we investigated the antitumor activity of a deoxynucleoside derivative, the protein kinase inhibitor compound 1-(β-D-2′-deoxyribofuranosyl)-4,5,6,7-tetrabromo-1H-benzimidazole (K164, also termed TDB), inter alia CK2 and PIM-1, on breast cancer cell lines (MDA-MB-231, MCF-7, and SK-BR-3).

Integracja europejska i współpraca regionalna w koncepcjach programowych parlamentarnych partii ludowych w Polsce (1989–2004)

Piotr Swacha
Celem artykułu jest analiza założeń programowych dotyczących polityki zagranicznej, które zostały sformułowane przez partie ruchu ludowego po roku 1989. Obszarem zainteresowania były kwestie stosunku do integracji europejskiej, koncepcji współpracy regionalnej, relacji Polski z sąsiadami, polskiej obecności w NATO oraz przyszłej wizji Unii Europejskiej. Analiza obejmuje programy przedwyborcze z lat 1991, 1993, 1997, 2001, jak również dokumenty programowe ogłoszone w 1989 r. przez dwa ugrupowania ruchu ludowego, które w tym okresie rozpoczęły swoją działalność.

Data from: Species interactions increase the temporal stability of community productivity in Pinus sylvestris-Fagus sylvatica mixtures across Europe

Forrester, Michael Heym, Václav Hurt, Viktor Kurylyak, Magnus Löf, Fabio Lombardi, Ekaterina Makrickiene, Bratislav Matovic, Frits Mohren, Renzo Motta, Jan Den Ouden, Maciej Pach, Quentin Ponette, Gerhard Schütze … & Lars Drössler
1.There is increasing evidence that species diversity enhances the temporal stability of community productivity in different ecosystems, although its effect at population and tree levels seems to be negative or neutral. Asynchrony in species responses to environmental conditions was found to be one of the main drivers of this stabilizing process. However, the effect of species mixing on the stability of productivity, and the relative importance of the associated mechanisms, remain poorly understood in forest...

Over 80 years without major disturbance, late successional Białowieża woodlands exhibit complex dynamism, with coherent compositional shifts towards true old‐growth conditions

Bogdan Brzeziecki, Kerry Woods, Leszek Bolibok, Jacek Zajączkowski, Stanisław Drozdowski, Kamil Bielak & Henryk Żybura
1. Controversies about successional dynamics of woodland communities have a long history, dating back to the classical debates between Clements and Gleason and continuing into the present. These debates have largely concerned the predictability or convergence of forest developmental trends as well as the relative importance of different mechanisms and forces driving forest succession. However, opportunities for rigorous testing of competing hypotheses are limited, mainly because plot-based studies of forest vegetation spanning more than a...

Data from: N-mixture models estimate abundance reliably: a field test on Marsh Tit using time-for-space substitution

Grzegorz Neubauer, Alicja Wolska, Patryk Rowiński & Tomasz Wesołowski
Imperfect detection in field studies on animal abundance, including birds, is common and can be corrected for in various ways. The binomial N-mixture (hereafter binmix) model developed for this task is widely used in ecological studies owing to its simplicity: it requires replicated count results as the input. However, it may overestimate abundance and be sensitive to even small violations of its assumptions. We used a 33-year dataset on the Marsh Tit, Poecile palustris, a...

Small-dimension drill-hole deflection in selected fibreboards

Patryk Król
The dataset consists of scans of MDF, HDF, and hard fibreboard specimens with holes of different diameters (0.5, 1.0, 2.0, 3.0 mm). NGC file attached as an example of gcode used (9 samples at once). Feedrates: 2, 6, 10, 16, 25, 35, 45 inch/min. The samples were made on a self-made milling machine and scanned with a flatbed scanner (Canon CanoScan LiDE 200, CIS technology, 4800 dpi).Samples were to correlate feed rate, material type, and...

Emerging stability of forest productivity by mixing two species buffers temperature destabilizing effect

Miren Del Rio, Ricardo Ruiz‐Peinado, Stig‐Olof Holm, Aris Jansons, Thomas Nord‐Larsen, Kris Verheyen, Andrés Bravo‐Oviedo, Hans Pretzsch, Ricardo Ruiz-Peinado, Hervé Jactel, Lluís Coll, Magnus Löf, Jorge Aldea, Christian Ammer, Admir Avdagić, Ignacio Barbeito, Kamil Bielak, Felipe Bravo, Gediminas Brazaitis, Jakub Cerný, Catherine Collet, Sonia Condés, Lars Drössler, Marek Fabrika, Michael Heym … & Andrés Bravo-Oviedo
The increasing disturbances in monocultures around the world are testimony to their instability under global change. Many studies have claimed that temporal stability of productivity increase with species richness, although the ecological fundaments have mainly been investigated through diversity experiments. To adequately manage forest ecosystems, it is necessary to have a comprehensive understanding of the effect of mixing species on the temporal stability of productivity and the way in which this it is influenced by...
