Currently established molecular methods for biomonitoring rely heavily on classic metabarcoding utilising short reads, mostly through Illumina data. However, increasingly more studies use long‐read sequencing technologies, such as Oxford Nanopore Technologies (ONT) and Pacific Biosciences (PacBio), for analyses of environmental DNA (eDNA) and DNA barcoding. These long‐read sequencing approaches can be advantageous over existing methods by providing increased information content and opening new avenues for understanding biodiversity at a larger scale.</jats:p>\n                      </jats:list-item>\n                      <jats:list-item>\n                        <jats:p>In this review, we provide an overview of studies to date using long‐read sequencing platforms for biodiversity analyses of eukaryotes, from eDNA and community metabarcoding, shotgun sequencing, and DNA barcoding. We also give detailed information on each step required for sample processing, data generation and analysis of long‐read sequencing datasets for biodiversity applications. Even though the number of studies using long‐read sequencing technologies is rapidly increasing, clear established guidelines for sample preparation or analysis of such datasets are lacking. Furthermore, a side‐by‐side review for both ONT and PacBio technologies across different applications has not been presented.</jats:p>\n                      </jats:list-item>\n                      <jats:list-item>\n                        <jats:p>Long‐read sequencing platforms provide possibilities for metabarcoding (PCR‐based) of both short and long fragments, shotgun sequencing (PCR‐free), or DNA barcoding. ONT platforms, in particular, can also allow real‐time data acquisition, while the portability of the MinION instrument can support sequencing in the field. PacBio, on the other hand, can provide highly accurate reads and can be used to reliably address open questions in ecology and evolution for difficult‐to‐characterise taxa such as microeukaryotes. Streamlining the use of these technologies could enable sequencing of whole organelles or population‐level assessments from environmental samples, which would be a step change for DNA‐based monitoring.</jats:p>\n                      </jats:list-item>\n                      <jats:list-item>\n                        <jats:p>Here, we review existing applications, applied methodology, and future perspectives in the field. Overall, we aim to facilitate the use of long‐read sequencing technologies by the wider community, promote best practices for data generation and standardised data reporting that supports reproducibility, and to encourage open data policies and tools.</jats:p>\n                      </jats:list-item>\n                    </jats:list>\n                  </jats:p>","journal":"Methods in Ecology and Evolution","year":2026,"id":5806,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.0496,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2026-01-30","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":55989,"name":"Alexandra Lino","orcid":null,"position":1,"is_corresponding":false},{"id":55988,"name":"Iliana Bista","orcid":"0000-0002-6155-3093","position":0,"is_corresponding":true}],"reference_count":119,"raw_metadata":null,"created_at":"2026-03-01T18:20:47.508186Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
