Phylogeny and systematics of the tribe Sonerileae (Melastomataceae) in Africa: A revised taxonomic classification

open access: yesJournal of Systematics and Evolution, Volume 61, Issue 4, Page 657-681, July 2023., 2023
The first in‐depth phylogenetic analysis of African Sonerileae to test monophyly of the currently recognized genera is here presented. Phylogenetic analyses neither support monophyly of the Old World nor African Sonerileae. The genera Calvoa, Dicellandra, Gravesia, and Preussiella form well‐supported clades while Amphiblemma and Cincinnobotrys are not ...

Histosols in an Upper Montane Environment in the Itatiaia Plateau [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2016
ABSTRACT: Highland environments favor accumulation and preservation of soil organic matter (SOM) due to low temperatures, leading to the formation of Histosols. The Itatiaia National Park (INP), Rio de Janeiro, Brazil, offers conditions for preservation of SOM deposited over time, which has led to the formation of these soils.

Liverworts show a globally consistent mid‐elevation richness peak

open access: yesEcology and Evolution, Volume 13, Issue 3, March 2023., 2023
The investigation of elevational gradients allows to draw conclusions on factors and mechanisms determining patterns in species richness distribution. In this study, we for the first time compared worldwide data of elevational species richness patterns of liverworts and found that a hump‐shaped pattern with highest richness at the middle of the ...

Unlocking the evolution of abdominal specializations in Luciuranus fireflies (Coleoptera, Lampyridae)

open access: yesZoologica Scripta, Volume 51, Issue 6, Page 708-723, November 2022., 2022
Abstract Understanding the evolution of genitalic traits and their co‐evolution between sexes is at the core of Evolutionary Biology. Cross‐species reproductive trait co‐variation can be the outcome of hybrid avoidance and/or sexual selection. Although the outcome of these two phenomena will look similar, they yield distinct patterns of species co ...
