Inhaltsbeschreibung top ↑

Die vorliegende Studie stellt mit Mitteln der klassischen morphologisch-anatomischen Merkmalsanalyse an 77 Gattungen eine phylogenetische Rekonstruktion der Jubulineae mit Schwerpunkt bei den Lejeuneaceae und Jubulaceae dar.
Erstmalig wurden 20 Sporophyten-Merkmale neu für die Wissenschaft erhoben, l2 bei einigen Gattungen bereits beobachtete Strukturen als Merkmale kodiert und 9 bereits in der Phylogenie verwendete Merkmale ausgeweitet und im Kontext bereits vorhandener Daten diskutiert. Die Sporophyten von 21 Gattungen wurden erstmalig bearbeitet, von l4 Gattungen wurden die Sporophyten fast vollständig neu bearbeitet, da nur zu maximal drei Merkmalen Literaturangaben vorhanden waren. Bei weiteren 42 Gattungen wurden bis über 70% der Merkmale neu erarbeitet oder mit umfangreichen neuen Daten ergänzt.
Die Sporophyten-Merkmale können systematisch verwendet werden und tragen zu einer natürlicheren Einteilung der untersuchten Gruppe bei.
In einer kladistischen Analyse konnte gezeigt werden, daß in allen Untersuchungen mit kombinierten Sporophyten- und Gametophyten-Merkmalen Goebeliella (Goebeliellaceae) separat in der Nähe der Außengruppe Porella steht. Die Jubulaceae bilden die Schwestergruppe zu den monophyletischen Lejeuneaceae. Innerhalb der Lejeuneaceae steht Nipponolejeunea (Subfam. Nipponolejeunoideae) als Schwestergruppe zur Kerngruppe. In dieser Gruppe befinden sich basal die Ptychantheae als paraphyletische Schwestergruppe zu den monophyletischen Lejeuneoideae, diese bestehen aus den Stictolejeuninae, den monophyletischen Brachiolejeuninae und den monophyletischen Lejeuneae s.l.. Innerhalb der Lejeuneae bilden die „Cololejeuneen“ und die „Omphalantheen“ monophyletische Gruppen. Die „Tuyamaelleen“ erwiesen sich jedoch als polyphyletisch durch die Sonderstellung von Haplolejeunea.

Synopsis top ↑

This study presents a phylogenetic analysis of 77 genera of Jubulaceae and Lejeuneaceae (Jubulineae) and related groups, using morphological and anatomical characters of gametophytes and sporophytes.
The sporophytes of 21 genera were examined for the first time, those of 14 other ones were almost completely newly described. For additional 42 genera more than 60% of the characters were either re-examined or complemented with more comprehensive new data.
The study shows that sporophytic characters are important to provide a natural classification of the investigated group.
The phylogenetic analysis showed that Goebeliellaceae are the sister group of the Porellaceae and Jubulaceae of the (monophyletic) Lejeuneaceae.
Within Lejeuneaceae the Nipponolejeunea (subfam. Nipponolejeunoideae) form a sister group to the core group, based on the paraphyletic Ptychanthoideae and the monophyletic Lejeuneoideae. Within the Lejeuneae the “Cololejeunoideae” and the “Omphalanthus-complex” form monophyletic groups, the “Tuyamaelloideae” however, turn out to be polyphyletic when Hapolejeunea is included.

The study presents the relationship of species of 77 genera of Jubulaceae and Lejeuneaceae and related groups, based on morphological and anatomical characters.

The author shows that sporophytic characters are most important. Beside this,sporophytes of 21 genera were examined for the first time. Due to the systematic the Goebeliellaceae are placed near Porella, and the Jubulaceae are a sister group of theLejeuneaceae. Most valuable is the presentation of new morphological and anatomical dates.

Review: The Bryologist 106(2),p.344 (2003) top ↑

Morphologically, the Lejouneaceae are one of the most diverse bryophyte families in existence. Hepaticologists continue trying to understanding how this startling display of variability can be used to unlock the evolutionary history of the family. Perhaps due to the conspicuousness and aesthetic allure of the gametophyte, its characters have been consistently over-represented relative to those of the more ephemeral sporophyte in systematic studies of the Lejouneaceae. In this book, Gabriele Weis demonstrates that the neglected diploid generation offers a viable source of data for reconstructing evolutionary relationships both within the family, and among other closely allied Jungermannalian taxa. The book includes a large phylogenetic analysis based on sporophytic features, and offers a refreshing taxonomic alternative in an era where morphology-based phylogenies too consistently take a back seat to gene-genealogies.
Weis has organized her book into four sections:
1) an introduction detailing the taxa used in her survey, and including a 45-word glossary of salient anatomical terms, as well as an historical review (1838 to the present) of research previously conducted on sporophytes of the Lejouneaceae and Jubulaceae;
2) a conspectus of written descriptions and SEM photographs of sporophyte features (e.g., foot, seta, inner and outer capsule structure, elator, and spore surface) from 231 species in 77 genera representing four families;
3) a phylogenetic analysis based on 36 coded sporophyte features from more than 70 taxa; and
4) a summary of previously published broad-scale systematic research on the Jungermanniales, I found Weis's concise summaries of earlier hypotheses on the phylogeny of the Jungermanniales not only place her new results in an historical context, but also offer the reader insight into the myriad phylogenetic hypotheses generated over nearly two centuries of taxonomic research. Her quantitative (e.g., cladistic) approach to her analyses demonstrates strong support of many traditionally accepted sub-familial relationships within the Lejouneaceae. In my opinion, one of the more interesting results is the discovery of Cololejeunioideae (e.g., facultative epiphyllous taxa) as a well-supported monophyletic clade sister to the sprawling Lejeunioideae complex.
The historical summary ends with a treatment of sub-familial taxonomy within the Lejouneaceae differing only marginally from other recent treatments. Although we have a long road ahead to understanding the full extent of evolutionary relationships within the Lejeunaceae, Gabriele Weis has convincingly demonstrated that patterns in sporophyte morphology are important pieces of the large taxonomic puzzle presented by this fascinating family of hepatics. For hepaticologists who truly understand the anonymous quote on the book's title page ("Small things mean nothing, till you see them"), her book is a necessity.
