Ten Simple Rules to build a Model Life Cycle

Timothée Poisot, Daniel J Becker, Cole B Brookson, et al.

Published: 2024-02-09
Subjects: Bioinformatics, Ecology and Evolutionary Biology, Software Engineering

Just like data, models have their own life cycle. By recognizing how one’s model fits within the life cycle of the data (or at least, ensuring that the model life cycle is understood), we can identify opportunities to foster new collaborations, encourage better practices in data analysis, and ultimately accelerate research. In this manuscript, we introduce the Model Life Cycle and develop a [...]

A universal DNA barcode for the Tree of Life

Bruno A S de Medeiros, Liming Cai, Peter J Flynn, et al.

Published: 2024-01-18
Subjects: Bioinformatics, Computational Biology, Genomics, Other Ecology and Evolutionary Biology

Species identification using DNA barcodes has revolutionized biodiversity sciences and society at large. However, conventional barcoding methods do not reflect genomic complexity, may lack sufficient variation, and rely on limited genomic loci that are not universal across the Tree of Life. Here, we develop a novel barcoding method that uses exceptionally low-coverage genome skim data to create a [...]

A big data and machine learning approach for monitoring the condition of ecosystems

Ecosystems are highly valuable as a source of goods and services and as a heritage for future generations. Knowing their condition is extremely important for all management and conservation activities and public policies. Until now, the evaluation of ecosystem condition has been unsatisfactory and thus lacks practical implementation for most countries. We propose that ecosystem integrity is a [...]

1. Understanding the processes underlying the distribution of species through space and time is fundamental in several research fields spanning from ecology to spatial epidemiology. Correlative species distribution models (SDMs) involve popular statistical tools to infer species geographical distribution thanks to spatiotemporally explicit observations of species occurrences coupled with a set of [...]

Don’t make genetic data disposable: Best practices for genetic and genomic data archiving

Deborah M Leigh, Amy Vandergast, Maggie Hunter, et al.

Published: 2023-09-25
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences

In ecology and evolution, genetic and genomic data are commonly collected for a vast array of scientific and applied purposes. Despite mandates for public archiving, such data are typically used only once by the data-generating authors. The repurposing of genetic and genomic datasets remains uncommon because it is often difficult, if not impossible, due to non-standard archiving practices and [...]

CasPEDIA Database: A Functional Classification System for Class 2 CRISPR-Cas Enzymes

Benjamin A Adler, Marena I Trinidad, Daniel Bellieny-Rabelo, et al.

Subjects: Biochemistry, Biophysics, and Structural Biology, Bioinformatics, Life Sciences

CRISPR-Cas enzymes enable RNA-guided bacterial immunity and are widely used for biotechnological applications including genome editing. In particular, the Class 2 CRISPR-associated enzymes (Cas9, Cas12 and Cas13 families), have been deployed for numerous research, clinical and agricultural applications. However, the immense genetic and biochemical diversity of these proteins in the public domain [...]

STRyper: an open source macOS application for microsatellite genotyping

Jean Peccoud

Published: 2023-07-29
Subjects: Biodiversity, Bioinformatics, Molecular Genetics, Other Ecology and Evolutionary Biology

In the context of population genetics, microsatellite markers analyzed by capillary sequencing remain useful tools for quick genotyping and low-cost studies. This contrasts with the lack of a free application to analyze chromatograms for microsatellite genotyping that is designed for population geneticists. To fill this gap, I have developed STRyper, a macOS application whose source code is [...]

Understanding local plant extinctions before it’s too late: bridging evolutionary genomics with global ecology.

Moises Exposito-Alonso

Published: 2022-12-01
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Plant Sciences

Understanding evolutionary genomic and population processes within a species range is key to anticipating the extinction of plant species before it is too late. However, most models of biodiversity risk projections under global change do not account for the genetic variation and local adaptation of different populations. Population diversity is critical to understanding extinction because [...]

Best practices in designing, sequencing and identifying random DNA barcodes

Published: 2022-09-28
Subjects: Bioinformatics, Biotechnology, Cell and Developmental Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences

Random DNA barcodes are a versatile tool for tracking cell lineages, with applications ranging from development to cancer to evolution. Here we review and critically evaluate barcode designs as well as methods of barcode sequencing and initial processing of barcode data. We first demonstrate how various barcode design decisions affect data quality and propose a new optimal design that balances [...]

Maintenance and expansion of genetic and trait variation following domestication in a clonal crop

Oliver White, Manosh Biswas, Wendawek M. Abebe, et al.

Published: 2022-09-01
Subjects: Agriculture, Bioinformatics, Biosecurity, Genetics and Genomics, Genomics, Life Sciences, Plant Sciences

Clonal propagation enables favourable crop genotypes to be rapidly selected and multiplied. However, the absence of sexual propagation can lead to low genetic diversity and accumulation of deleterious mutations, which may eventually render crops less resilient to pathogens or environmental change. To better understand this trade-off, we characterise the domestication and contemporary genetic [...]

European light skin may have evolved as an adaptation to the Neolithic sedentary lifestyle

Manuel Ferrando-Bernal

Published: 2022-07-27
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Population Biology

Light skin facilitates the penetration of ultraviolet light (UV) radiation through the skin, increasing the synthesis of vitamin D that in turn stimulates bone formation. It has been suggested that light skin appeared in the ancestors of modern Europeans as an adaptation to the conditions of low UV radiation in high latitudes; however, paleogenetic studies have recently shown it did not evolve [...]

The coevolutionary mosaic of bat betacoronavirus emergence risk

Pathogen evolution is one of the least predictable components of disease emergence, particularly in nature. Here, building on principles established by the geographic mosaic theory of coevolution, we develop a quantitative, spatially-explicit framework for mapping the evolutionary risk of viral emergence. Driven by interest in diseases like SARS, MERS, and COVID-19, we examine the global [...]
