Microbial Phylogeny

Microbial Phylogeny

Understanding the evolutionary relationships among microorganisms is fundamental to microbial ecology and taxonomy. Phylogenetic trees are essential tools for inferring these relationships, relying primarily on comparative analyses of molecular sequences such as DNA, RNA, or proteins. In microbial studies, these trees typically depict the evolutionary paths of diverse bacterial and archaeal species by mapping genetic differences accumulated over time.Phylogenetic trees are composed of tips,...

Ecological Disturbance

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

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...

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...

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.

Area of Science:

Ecology
Evolutionary Biology
Biogeography

Background:

Ecologists often use single phylogenetic trees, overlooking their hypothetical nature and limitations with incomplete data.
Phylogenetic uncertainty is frequently unquantified in ecological analyses, potentially distorting evolutionary process inferences.

Purpose of the Study:

To introduce a novel analytical strategy for maximizing incomplete phylogenetic information.
To account for multiple sources of phylogenetic uncertainty in macroecological and trait evolution studies.

Main Methods:

Developed a new analytical strategy to incorporate incomplete phylogenetic data.
Applied the method to a clade-wide hummingbird analysis, assessing uncertainty impacts on trait evolution and biogeography.

Main Results:

The proposed method effectively utilizes incomplete phylogenetic information.
Demonstrated how phylogenetic uncertainty influences comparative analyses of trait evolution and biogeographic patterns.

Conclusions:

The strategy broadens the scope of evolutionary studies with limited phylogenetic data.
Enables estimation and control of statistical errors stemming from phylogenetic uncertainty.
