Andrzej Witkowski Livres

This impressive volume features twenty-nine peer-reviewed contributions that encompass the full spectrum of current diatom research. Topics include the taxonomy of freshwater and marine diatoms, fossil records from various habitats, planktonic diatoms, and the potential of diatoms and ostracods as bioindicators. It also explores the application of diatom assemblages in climatic reconstructions, the use of molecular tools in phylogeny, and the threat posed by invasive and potentially toxic diatoms, alongside highlights from the diatom collection of Józef Pantocsek. The diverse subjects reflect the extensive research interests of Prof. Horst Lange-Bertalot. These papers were contributed by colleagues and friends in celebration of his 75th birthday during the 5th Central European Diatomologists Meeting in Szczecin, Poland, in February 2011. Many authors have drawn from Prof. Lange-Bertalot’s deep knowledge and floristic expertise. His remarkable contributions to diatom research have significantly influenced ecology, biodiversity, and conservation, particularly in water quality assessment, European and global floristics, and synthesizing these studies. This volume serves as a tribute to Professor Lange-Bertalot, a leading diatom taxonomist, and will be of great interest to researchers focused on diatoms and their ecological impacts.

Several hundred samples collected from marine coasts of various geographic regions have been primarily studied by means of light microscopy supplemented by SEM and TEM observations. As a result almost 2000 taxa could be identified. The first volume contains ca. 1100 taxa representing 120 genera illustrated on 219 plates in 4504 micrographs. A considerable number of taxa was compared with the original (type) material. 30 new species or infraspecific taxa and 10 new genera are described. The material studied originates from temeperate zones, the Arctic and (sub) tropic climates of both hemispheres. Our intention in preparing - step by step- the diatom flora of marine coasts is to provide diatomologists working in the marine littoral with an equivalent of the „Süßwasserflora von Mitteleuropa“ by Krammer and Lange-Bertalot. We hope the first volume will help to fill up the considerable deep gap of knowledge. Freshwater diatoms are commonly better known whereas the identities of marine species are much more questionable. Our biggest handicap up to now has been inadequate microphotographic information on species diversity in the marine littoral.

Ks. Jerzy Popiełuszko został porwany 19 października 1984 roku w Górsku. Zamordowali go w sposób bestialski funkcjonariusze Służby Bezpieczeństwa. To makabryczne morderstwo było szokiem dla społeczeństwa i po raz kolejny pokazało, że komunistyczne władze nie mają oporów wobec swoich przeciwników i nikt nie może czuć się bezpiecznie, nawet kapelan Solidarności. Prokurator Andrzej Witkowski był osobą która była najbliżej wyjaśnienia sprawy. W rozmowie z Ryszardem Gromadzkim opowiada kulisy sprawy która pomimo upływu prawie 40 lat nie może znaleźć swojego finału, a rozwikłanie jej może sprawić, że historię PRL i transformacji trzeba będzie napisać od nowa.
