Convergent Evolution

Convergent Evolution

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while microarray-based...

Area of Science:

Bioacoustics
Animal Behavior
Computational Biology

Background:

Analyzing multi-individual vocalizations is challenging due to microphone clock drift and noise.
On-board recording devices are increasingly used, generating complex datasets.

Purpose of the Study:

Introduce callsync, an R package to process and analyze animal vocal recordings.
Address issues of recording alignment, vocalization detection, assignment, and noise filtering.

Main Methods:

Developed callsync, an R package for bioacoustic data processing.
Applied the package to cockatiel vocalization recordings with significant clock drift.
Utilized spectrographic cross-correlation for vocal similarity assessment.

Main Results:

Successfully aligned recordings with initial drift of ~2 minutes to within ~2 seconds.
Detected and assigned 2101 vocalizations from multi-hour recordings.
Demonstrated the package's effectiveness with and without auditory markers.

Conclusions:

The callsync package provides a robust pipeline from raw audio to analyzed vocal features.
It offers modularity, allowing users to customize analysis steps.
Facilitates advanced study of animal communication in multi-individual settings.
