Article
Aim The latitudinal diversity gradient (LDG) is a primary emergent property of the biosphere, yet the cause(s) of this pattern are still debated. Key to many hypotheses is the origins and maintenance of tropical hyperdiversity, and the role of climate in driving low latitude speciation. Here, we analyse patterns of tropical and extratropical floral...

The project represents a comprehensive application of X-ray and neutron radiography in palaeontology, particilarly palaeobotany. These methods, the cutting edge technologies in palaeontological research worldwide, enable the investigation of anatomical characters of fossils in a progressive, nondestructive way. The chosen approach is particularly suitable for unique, delicate and rare specimens. Radiographic non-destructive imaging methods will provide data suitable for 3D modeling. The examination of anatomical characters of well preserved fossilswill enable better understanding of their evolution and systematics. The developed specific methodologies will be tested through case studies based on Cretaceous fossil plants from the pteridophyte families, conifers and angiosperms

NECLIME is an open international network of scientists working on Cenozoic climate evolution and related changes of continental ecosystems. During the past 65 million years of Earth history, globally warmer-then-present conditions prevailed in a world with almost modern paleogeography. These timespans represent promising case studies for anticipated future scenarios. Within the NECLIME network, we aim to combine data on past climate change and its environmental impact for large-scale reconstructions. NECLIME research activities comprise paleoclimate reconstructions, including atmospheric CO₂ and ecosystem analysis using multiple quantitative methods on various primarily continental proxies (plants; vertebrates; invertebrates; geochemistry and geological proxies). Complementing model studies are employed to assess connections and processes driving ocean, atmosphere and biosphere at global and regional scales. NECLIME was established in 1999 with the aim to understand Neogene trends across Eurasia. This basic idea quickly and constantly expanded to a global interest and a wider stratigaphical frame. The steadily growing NECLIME network with currently around 140 members in 34 countries is coordinated by a team of researchers and an advisory board. NECLIME holds annual conferences and workshops and administers working groups bringing forward scientific exchange, joint projects, and the integration of research data.

Editor-in-Chief, THE INTERNATIONAL FOSSIL PLANT NAMES INDEX (IFPNI) since May, 2014. IFPNI is an online database [http://ifpni.org] of fossil names of plants, algae, fungi, allied prokaryotic forms (formerly treated as algae and Сyanophyceae in particular), algae-related protists and fossil microproblematica (so-called ‘ambiregnal’ organisms). IFPNI is a platform to provide an online, open-access, and community-generated registry of fossil plant nomenclature as a service to the global scientific community. Dynamic database aims to document all nomenclatural novelties (new scientific names of extinct organisms) and associated data, including registry of the scientific publications (taxonomic literature) containing nomenclatural acts, and authors in palaeobotany/palaeontology. Establishing IFPNI as a global registry of fossil plant names will largely provide an opportunity to introduce unprecedented stability into botanical nomenclature. Not only will taxonomic data be freely available, but also an alerting-service targeting taxa of interest to particular user groups will be provided. The IFPNI interface will provide automatic checking for Code-compliance, and thus prevent new homonymy, stabilize spellings, fix genders and stems, and provide stability in gender agreement. A possible additional benefit of IFPNI would be universal availability of new original descriptions and partially original descriptions from retro literature. The database is not yet complete, and more work should be done on some remained to verified and analyzed data. As a result for the work 2014-onwards, at present IFPNI has registered 76632 names from 9576 publications from 1626 journals and 959 books authored by 5097 authors [statistics on 18 May 2021].
