Migration

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

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,...

Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

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...

Area of Science:

Computational biology
Phylogenetics
Epidemiology

Background:

Understanding species movement and dispersal is crucial in ecology and epidemiology.
Phylogenetic methods offer insights into evolutionary history and spatial spread.
Integrating environmental data with phylogenetic information can reveal movement drivers.

Purpose of the Study:

To introduce SERAPHIM (Studying Environmental Rasters and PHylogenetically Informed Movements), a novel computational method.
To enable the analysis of environmental factors influencing phylogenetic reconstructions of spatial movement.
To provide tools for visualizing dispersal history and assessing the impact of environmental variables on organism spread.

Main Methods:

SERAPHIM extracts spatio-temporal data from phylogenetic trees.
It calculates environmental "weights" for phylogenetic branches based on raster data.
Correlations between movement duration and environmental weights are assessed using randomization procedures.

Main Results:

SERAPHIM quantifies the influence of environmental variables on lineage movement.
It provides statistical significance for the impact of environment on dispersal.
The method visualizes spatial spread and dispersal history.

Conclusions:

SERAPHIM offers a robust framework for studying phylogeography in an environmental context.
The method is applicable to any phylogeny with spatial and temporal data.
It is particularly relevant for emerging infectious disease research and growing population genomic datasets.
