Karyological analyses of Pseudhymenochirus merlini and Hymenochirusboettgeri provide new insights into the chromosome evolution in theanuran family Pipidae
No full texttKaryological studies continue to clarify the evolutionary history of many taxa. We report here on thefirst chromosome survey of the frog Pseudhymenochirus merlini (Pipidae) in comparison with the relatedspecies Hymenochirus boettgeri.In addition to the 2n = 20 regular (A) chromosomes (eight metacentric and two subtelocentric pairs),H. boettgeri has an accessory B chromosome in about half of the scored karyotypes (2n = 21). P. merlinishowed a karyotype of 2n = 20 chromosomes, differing from the set of A chromosomes of H. boettgeri bythree inversions.Other differences are in the location of the nucleolus organizer regions (NORs), on the 10th chromosomepair in P. merlini instead of the 4th pair in H. boettgeri. Heterochromatin is less abundant in P. merlini, andlocalized in centromeric and telomeric regions of all chromosomes. The patterns in H. boettgeri resemblethose of another pipid species, Silurana tropicalis, as to chromosome number (2n = 20), morphology, andG-banding patterns. We propose that these characteristics are symplesiomorphic in Pipidae, allowing usto present a scenario for the chromosome evolution in this family. Our results identify a third mecha-nism of increase in chromosome numbers among pipid frog species, the addition of B chromosomes inHymenochirus, besides the known processes of polyploidization in Xenopus/Silurana, and centric fissionin Pipa
The Poem of Memory. "Triumphi"
No full textWriting of the "Triumphi" Fabio Finotti finds that its author undercuts a medieval idea of ascent to God in the structural progression from Love to Chastity, Death, Fame, Time, and Eternity. Here Petrarch programmatically counters Dante, transforming a universal, eschatological vision into a subjective, cultural and psychological experience

Prof. Tronchetti’s scholarly is primarily in the areas of international space law and public international law. His publications include two books and more than 20 articles in internationally peer-reviewed space law and policy journals, such as Space Policy, the German Journal of Air and Space Law, the Journal of Space Law, etc.
He holds a PhD in International Space Law (Leiden University) and an Advanced LL.M in International Relations (Bologna University, Italy). He is Member of the International Institute of Space Law (IISL), European Centre for Space Law (ECSL), and the Asian Society of International Law (ASIL). He is the recipient of the 2007 Diederiks-Verschoor award for the best paper submitted by an author not older than 40 years to the International Institute of Space Law (IISL) during the 58th International Astronautical Congress of the International Astronautical Federation (IAF).https://commons.erau.edu/stm-images/1076/thumbnail.jp
