Abstract
DNA technologies have many advantages for biomonitoring and biodiversity analyses, but these depend on the availability of relevant reference DNA barcodes. To be most useful, a DNA barcode should be linked to a taxonomic name, which can in turn be connected to ecological information. This linking can be achieved by DNA barcoding of taxonomically identified specimens. Museums are a promising source of such specimens, but the DNA in museum specimens is often degraded, necessitating carefully optimised DNA extraction methods. In this issue of Molecular Ecology Resources, Holmquist et al. (2025) present a DNA extraction protocol for museum insect specimens, using in-house formulated Solid Phase Reversible Immobilisation (SPRI) beads. The authors carried out several experiments with statistical evaluation to determine optimal DNA extraction parameters, before testing the protocol on a large and diverse pool of museum-held insect specimens. The result is a low-cost and effective DNA extraction protocol for diverse museum insect specimens.
期刊介绍：
Molecular Ecology Resources promotes the creation of comprehensive resources for the scientific community, encompassing computer programs, statistical and molecular advancements, and a diverse array of molecular tools. Serving as a conduit for disseminating these resources, the journal targets a broad audience of researchers in the fields of evolution, ecology, and conservation. Articles in Molecular Ecology Resources are crafted to support investigations tackling significant questions within these disciplines.
In addition to original resource articles, Molecular Ecology Resources features Reviews, Opinions, and Comments relevant to the field. The journal also periodically releases Special Issues focusing on resource development within specific areas.
