Article
Effective communication of taxonomic concepts is crucial to meaningful application in all biological sciences, and thus the development and following of best practices in taxonomy and the formulation of clear and practical rules of nomenclature underpin a wide range of scientific studies. The International Code of Nomenclature for algae, fungi and...
Conference Paper
Full-text available
The timing of the origins of angiosperms is a long-standing topic of debate in plant evolution. Different disciplines and approaches provide highly variable age estimates. It is generally accepted, that early macro- and mesofossils showing unequivocal angiosperm features occur in lower Aptian deposits. The oldest widely accepted fossilized flowers...

Thesis
Full-text available
The overarching aim of this thesis was to integrate the Bonenburg section and its extremely well- preserved palynoflora within the existing framework of end-Triassic records, and describe and compare its paleoenvironmental changes and vegetation history during the end-Triassic mass extinction. In 􏰀􏰁􏰂􏰃􏰄 the outcrop of 􏰅Bonenburg􏰆 in Western Germany...
Article
This is a biography and obituary of the German Democratic Republic palynologist Dr Eberhard Schulz (1931–2017). A pioneer in Mesozoic palynology, he established, together with other important palynologists of that time, the basis of today’s palynological research, especially in the Triassic and Jurassic of Eastern Germany. His comprehensive range c...
Conference Paper
Full-text available
A disturbed spore/pollen production can result in increased amounts of abnormal spores or pollen. Usually, this is linked to naturally occurring environmental stress in the mother plant due to sudden changes related to weather, e.g. draught, water logging, temperature changes, in which case the environmental stress is seasonal and may only affect p...

Project
How far can we reliably back in the pollen record to find the oldest angiosperms? Focusing on pre-Aptian records of the Lusitanian Basin/ Portugal and using fluorescent microscope techniques to find the needle in the haystack.
Project
Taxonomy is the very basis of all subsequent paleopalynological studies, be it for environmental reconstructions, diversity estimates or evaluation of teratology. Although taxonomy got a bit 'out of fashion' due to temporal and financial limitations, this project reevaluates original type material in joined view with newer and better-studied sections. Together with an eye on nomenclature, this is to complement other studies and further the taxonomical knowledge that is the palynologists#' 'daily bread'.
Project
When we study literature at school or university, we always learn about the historical background of the body of text in question. I believe that considering the historical background of scientific texts helps us as well to interpret older literature and should therefore be a concomitant field of study. At the moment we face a turnover in scientists - many positions in many different institutions are lost and lack of succession poses the threat that a lot of diligently collected information gets lost. In order to bridge this problem, this project attempts to preserve historical knowledge about palynology and the people that shaped it.
