Molecular phylogenetic evaluation of classification and scenarios of character evolution in calcareous sponges (Porifera, Class Calcarea). [PDF]
, 2012 Calcareous sponges (Phylum Porifera, Class Calcarea) are known to be taxonomically difficult. Previous molecular studies have revealed many discrepancies between classically recognized taxa and the observed relationships at the order, family and genus ...

Evolution, Volume 76, Issue 12, Page 3041-3053, December 2022., 2022 Abstract Rensch's rule suggests that sexual size dimorphism (SSD) increases with species size when males are the larger sex, whereas it decreases when females are the larger sex. However, the process responsible for this pattern remains obscure. SSD can result from sexual selection, such as intrasexual competition for access to mates, or from natural ...

Revista Brasileira de Entomologia, 2002 Traditionally, the Drosophila guarani species group has been divided into two subgroups: the guarani and the guaramunu subgroups. Two, out of the four species included in this research, are members of the guarani subgroup (D. ornatifrons Duda, 1927 and D.

Phylogeny of the Neotropical element of the Randia clade (Gardenieae, Rubiaceae, Gentianales) [PDF]
Plant Ecology and Evolution, 2021 Background and aims – Generic limits of the tropical tribe Gardenieae (Ixoroideae, Rubiaceae) have partly remained unsettled. We produced a new phylogeny of the Randia clade, with emphasis on its Neotropical clade comprising five genera (Casasia, Randia,

Plant Systematics and Evolution, 2019 The monophyly of Nymphaeaceae (water lilies) represents an important, but controversial aspect in the effort to understand the evolutionary history of early-diverging angiosperms.

Recombination confounds the early evolutionary history of human immunodeficiency virus type 1: Subtype G is a circulating recombinant form [PDF]
, 2007 Human immunodeficiency virus type I (HIV-1) is classified in nine subtypes (A to D, F, G, H, J, and K), a number of subsubtypes, and several circulating recombinant forms (CRFs).

A Likelihood-Ratio Test of Monophyly [PDF]
Systematic Biology, 1996 Many phylogenetic analyses are inspired by or depend upon the monophyly of a group specified a priori. Also, many evolutionary problems for which phytogenies are useful do not require every detail of the phylogeny to be estimated correctly but depend upon the monophyly (or lack thereof) of a particular group.

Pangenomic Definition of Prokaryotic Species and the Phylogenetic Structure of Prochlorococcus spp.
Frontiers in Microbiology, 2018 The pangenome is the collection of all groups of orthologous genes (OGGs) from a set of genomes. We apply the pangenome analysis to propose a definition of prokaryotic species based on identification of lineage-specific gene sets.

Strong phylogenetic congruence between Tulasnella fungi and their associated Drakaeinae orchids
Journal of Evolutionary Biology, Volume 36, Issue 1, Page 221-237, January 2023., 2023 Representatives of five genera of Drakaeinae orchids, from top left to bottom right: Arthrochilus latipes, Chiloglottis trilabra, Caleana major, Paracaleana minor, Drakaea livida. Abstract The study of congruency between phylogenies of interacting species can provide a powerful approach for understanding the evolutionary history of symbiotic ...
