RaxmlGUI 2.0: A graphical interface and toolkit for phylogenetic analyses using RAxML

Edler, Daniel ; Klein, Johannes ; Antonelli, Alexandre ; Silvestro, Daniele

In: Methods in Ecology and Evolution, 2020, vol. -, no. -, p. -

raxmlGUI is a graphical user interface to RAxML, one of the most popular and widely used softwares for phylogenetic inference using maximum likelihood.Here we present raxmlGUI 2.0, a complete rewrite of the GUI which seamlessly integrates RAxML binaries for all major operating systems with an intuitive graphical front‐end to setup and run phylogenetic analyses.Our program offers automated...

Impossibility results on stability of phylogenetic consensus methods

Delucchi, Emanuele ; Hoessly, Linard ; Paolini, Giovanni

In: Systematic Biology, 2020, vol. 69, no. 3, p. 557–565

We answer two questions raised by Bryant, Francis, and Steel in their work on consensus methods in phylogenetics. Consensus methods apply to every practical instance where it is desired to aggregate a set of given phylogenetic trees (say, gene evolution trees) into a resulting, “consensus” tree (say, a species tree). Various stability criteria have been explored in this context, seeking...

Richness, phylogenetic diversity, and abundance all have positive effects on invader performance in an arid ecosystem

El‐Barougy, Reham ; Mac, Ivor, J. Scott ; Arnillas, Carlos A. ; Nada, Reham M. ; Khedr, Abdel‐Hamid A. ; Cadotte, Marc W.

In: Ecosphere, 2020, vol. 11, no. 2, p. -

In search of generalities in biological invasions, it is sometimes forgotten that invader success can be a function of both the diversity of the invaded community and the relatedness of the invader relative to community residents. Both qualities are likely to be especially important in stressful ecosystems, and identifying the species and community attributes that influence biological ...

Phylogenetic diversity is a better predictor of wetland community resistance to Alternanthera philoxeroides invasion than species richness

Qin, Tian‐Jian ; Zhou, Jian ; Sun, Yan ; Müller‐Schärer, Heinz ; Luo, Fang‐Li ; Dong, Bi‐Cheng ; Li, Hong‐Li ; Yu, Fei‐Hai

In: Plant Biology, 2020/n/a/n/a/-

Highly biodiversity communities have been shown to better resist plant invasions through complementarity effects. Species richness (SR) is a widely used biodiversity metric but lacks explanatory power when there are only a few species. Communities with low SR can have a wide variety of phylogenetic diversities (PD), which might allow for a better prediction of invasibility. We assessed the...

Biogeography and phylogenetic relationships of Hyrcanian wild apple using cpDNA and ITS noncoding sequences

Yousefzadeh, Hamed ; Khodadost, Ali ; Abdollahi, Hamid ; Ali, Syed Shujait ; Kozlowski, Gregor ; Bina, Hamid

In: Systematics and Biodiversity, 2019, vol. 17, no. 3, p. 295–307

The Hyrcanian forest of northern Iran is considered one of the potential centres for the evolution and domestication of the genus Malus (Rosaceae). However, the biogeography, phylogenetic position, and taxonomic status of the Hyrcanian wild apples have never been evaluated. In our study, the nucleotide sequences of the internal transcribed spacer (ITS) and the trnH-psbA intergenic spacer...

Necrosaurus or Palaeovaranus? Appropriate nomenclature and taxonomic content of an enigmatic fossil lizard clade (Squamata) = Necrosaurus ou Palaeovaranus ? Nomenclature appropriée et contenu systématique d’un clade énigmatique de lézards fossiles (Squamata)

Georgalis, Georgios L.

In: Annales de Paléontologie, 2017, vol. 103, no. 4, p. 293–303

Necrosaurus cayluxi is an enigmatic lizard from the Paleogene of the Phosphorites of Quercy, France that was first mentioned in the 19th century. Although it is generally believed that Filhol was the author who established this taxon, I am herein demonstrating that authorship should in fact be attributed to Zittel, a fact that also influences not only its generic nomenclature, but also its...

Ordering by the numbers in anatomy and by letters Too

Neumann, Paul E. ; Baud, Robert ; Sprumont, Pierre

In: Clinical Anatomy, 2017, vol. 30, no. 6, p. 700–702

Here, new rules of Latin anatomical nomenclature are proposed to deal with cases not covered by existing or other recommended rules. Determiners (e.g., numerals, letters, alphanumeric strings, and Latin names of Greek letters) should follow the noun they specify or limit, just as it is recommended that adjectives should follow the noun they modify. In general, Roman numerals, Latin letters,...
