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 [...]

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 [...]

Broad-scale Applications of the Raspberry Pi: A Review and Guide for Biologists

The field of biology has seen tremendous technological progress in recent years, fuelled by the exponential growth in processing power and high-level computing, and the rise of global information sharing. Low-cost single-board computers are predicted to be one of the key technological advancements to further revolutionise this field. So far, an overview of current uptake of these devices and a [...]

Diversity and structure of arbuscular mycorrhizal fungal commmunities and their chemical drivers across dryland habitats in Qatar

Sakeenah Adenan, Jane Oja, Juha Alatalo, et al.

Subjects: Biodiversity, Bioinformatics, Biotechnology, Desert Ecology, Ecology and Evolutionary Biology, Life Sciences

Qatar is largely characterized by a hyper-arid climate and low soil fertility, which combine to create a stressful soil environment for arbuscular mycorrhizal (AM) fungi. Here we present a study on AM fungi communities and their relationship to soil chemical characteristics. We used high-throughput seqeuncing technique for identifying AM fungal diversity and community composition from different [...]
