Resumen

Este estudio establece la clasificación subgenérica formal para el género Merodon (Diptera: Syrphidae). Los datos combinados moleculares y morfológicos revelan cinco nuevos subgéneros dentro de este diverso grupo de insectos europeos.

Área de la Ciencia:

Entomología
Estudio sistemático
Biología evolutiva

Sus antecedentes:

El género Merodon es el género de moscas voladoras más rico en especies de Europa.
Las investigaciones anteriores se han centrado principalmente en la taxonomía a nivel de especie y los rasgos fenotípicos, con una investigación limitada de las relaciones filogenéticas intragenéticas.

Objetivo del estudio:

Establecer una clasificación subgenérica formal para el género Merodon.
Resolver las relaciones filogenéticas dentro del género Merodon utilizando datos moleculares y morfológicos integrados.

Principales métodos:

Compilación de un conjunto de datos de carácter morfológico para Merodon y taxones relacionados.
Generación de datos moleculares utilizando COI mitocondrial y secuencias de genes de ARNr nucleares 28S y 18S.
Análisis filogenéticos combinados utilizando métodos de parsimonia y de máxima probabilidad.

Principales resultados:

El análisis integrado de 3151 caracteres (2947 bp moleculares, 204 morfológicos) en 80 taxones apoyó una nueva clasificación.
Se identificaron y describieron formalmente cinco nuevos subgéneros: Albimerodon. Nov., subgénero Auremerodon. Nov., del subgénero Avidumerodon. Nov., del subgénero Desutumerodon. nov., y el subgénero Natamerodon. No lo sé.

Conclusiones:

El estudio proporciona un marco filogenético robusto para el género Merodon.
Los subgéneros recién descritos ofrecen una clasificación refinada para este importante grupo europeo de sobrevuelo.

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Phylogeny

Phylogeny

Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

Phylogenetic Trees

Phylogenetic Trees

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

Gene Evolution - Fast or Slow?

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...
