This is an integrated introduction to methods, design, and data analysis tailored to cross-cultural research. With examples from cognitive and educational assessment, personality, health, and management, this guide presents key methodological and statistical tools and focuses on the research questions that can be tackled with particular techniques.
From France to the sub-Antarctic islands. Celebrating the work and life of Prof. Dr. René Le Cohu on the occasion of his 80th birthday
This Beiheft of Nova Hedwigia features twenty contributions by more than 40 authors, representing the entire range of Prof. Le Cohu's work and interests. Topics of the contributions range from purely taxonomic papers to articles dealing with diatom biodiversity, ecology, paleoecology and biogeography. The papers apply both traditional and novel techniques. They describe more than 20 new species (high quality SEM images) and three new genera and several taxa are revised. Geographically, the contributions to this volume span a a wide region, from the part of France, where Ren� le Cohu started his research, to the sub-Antarctic Kerguelen Islands from where he has described a great number of species. This Beiheft is dedicated to Prof. Dr. Ren� Le Cohu on the occasion of his 80th birthday, in recognition of his life-long scientific work on the taxonomy and ecology of algae, and diatoms in particular. It addresses phycologists and other researchers working on diatoms and algae.
The freshwater and terrestrial diatom composition of the Subantarctic island Ile de la Possession is investigated in detail. The island is part of the Crozet Archipelago, situated in the southern Indian Ocean. A total of 220 diatom taxa, belonging to 44 genera have been identified after surveying more than 500 samples, taken from all over the island. The most diverse genera are Pirmularia (41 taxa), Nitzschia (19 taxa), Psammothidium (13 taxa) and Diadesmis (11 taxa). Detailed SEM analysis of all observed taxa resulted in the description of several new species and varieties, especially in the genera Diadesmis and Pinnularia, whereas several others need further observations to be described later on as new taxa. In addition, the taxonomy of the so-called Subantarctic taxa has been thoroughly revised based on the most recent insights. All taxa are morphologically and ecologically characterized and elaborately documented with both LM and SEM micrographs.
