--- name: molecular-ecology description: Use when targeting Molecular Ecology (Mol Ecol) or deciding whether a manuscript applying molecular approaches to ecological, evolutionary, or conservation questions fits this venue. Encodes the journal's fit, framing, method-and-evidence bar, house style, official-submission re-check, and desk-reject heuristics. --- # Molecular Ecology (molecular-ecology) ## Journal positioning Molecular Ecology is a Wiley journal and the flagship venue for work that uses molecular tools to answer ecological, evolutionary, and conservation questions. Its defining character is the integration of molecular data with a genuine ecological or evolutionary question: the molecular method is the means, not the end. The journal rewards population genomics, phylogeography, landscape genetics, molecular adaptation, eDNA and metabarcoding, host-microbe and community molecular ecology, and conservation genomics — provided the study is hypothesis-driven and the biological interpretation is as strong as the genetic analysis. It is not a venue for marker-development notes, methods without a biological question, or descriptive genotyping without ecological inference. Readership spans molecular ecologists, evolutionary geneticists, and conservation biologists. This skill is a **fit / venue-selection / re-framing** tool. It does not replace the journal's current official guidelines. Before submitting, re-check the live author instructions on the Molecular Ecology Wiley site. ## When to trigger - The author names Molecular Ecology as the target for a study applying molecular or genomic data to an ecological, evolutionary, or conservation question. - A population-genomics, phylogeography, eDNA, or landscape-genetics manuscript is choosing between Molecular Ecology, Molecular Biology and Evolution, and Nature Ecology & Evolution. - A study has strong molecular data but the author needs to confirm the ecological/evolutionary question is framed sharply enough for this venue. - The author needs Molecular Ecology's data-archiving, reproducibility, and scope conventions, plus desk-reject criteria, before submission. ## Scope & topic fit - Population genomics and landscape genetics: structure, gene flow, demographic history, and adaptation across landscapes inferred from genome-wide data. - Phylogeography: the geographic distribution of genealogical lineages and the historical processes — refugia, colonization, vicariance — that produced them. - Molecular adaptation and selection: genome scans, environmental-association analyses, and functional links between genotype, phenotype, and environment. - Environmental DNA, metabarcoding, and community molecular ecology: biodiversity assessment, species detection, and community composition from molecular data with ecological inference. - Host-microbe and symbiosis ecology: microbiome structure and function analyzed in an ecological or evolutionary framework. - Conservation genomics: effective population size, inbreeding, hybridization, units of conservation, and adaptive capacity informing management. ## Method & evidence bar - The ecological or evolutionary question must drive the study; molecular data are evidence toward a hypothesis, not the result in themselves. - Sampling design must support the inference: population/site replication, sample sizes, and geographic or temporal coverage adequate for the claims. - Genomic analyses must be current and appropriate — suitable marker density or sequencing depth, correct population-genetic models, and attention to confounders such as population structure, linkage, and ascertainment bias. - Statistical support is expected: model comparison, demographic-inference validation, simulation or resampling where relevant, and honest treatment of uncertainty. - Bioinformatic pipelines must be reproducible: software versions, parameters, and filtering steps reported; custom code deposited. - Raw sequence data and genotype/processed datasets must be archived in appropriate public repositories (e.g., NCBI SRA/GenBank, Dryad/Zenodo) per current policy. ## Structure & house style - Molecular Ecology publishes full-length research articles; re-check current article types, length, and figure limits on the live site. - The Introduction must establish the ecological/evolutionary question and hypotheses before the molecular approach; Methods document sampling, lab/sequencing, and bioinformatics in reproducible detail. - Results should integrate genetic patterns with biological interpretation rather than presenting genotype summaries in isolation; the Discussion must return to the opening question. - Figures favor informative population-genetic visualizations — structure plots, ordinations, maps, demographic models — each carrying a clear inference. - Extensive bioinformatic detail, parameter tables, and supplementary analyses belong in Supporting Information; the main text stays focused on the question. - A clear data-accessibility statement with all repository accessions is a standard required element; confirm the current format. ## Official-submission checklist - Before giving submission-ready advice, read `../../resources/source-basis.md` and `../../resources/official-source-map.md`; start from the official source anchors for this journal family, then cite the current journal-specific page you checked. - Search the live site for "Molecular Ecology author guidelines" and follow the current Wiley version. - Re-check current article types, length and figure limits, and any distinction between full articles and shorter formats. - Re-check the data-accessibility policy: required repositories for raw sequence data, genotypes, and code, plus the data-accessibility-statement format. - Re-check competing-interests, funding, ethics/permits (sampling, CITES), and AI-use disclosure requirements; confirm preprint policy (bioRxiv/EcoEvoRxiv generally compatible). - If the live official instructions conflict with this skill, the official instructions win. ## Pre-submission self-check - [ ] One sentence — the ecological or evolutionary question driving the study and how the molecular data answer it. - [ ] The molecular method is a means to a biological inference, not the manuscript's main result. - [ ] Sampling design and sample sizes support the population-genetic or phylogeographic claims. - [ ] Bioinformatic pipeline is reproducible: versions, parameters, and filtering reported. - [ ] Raw sequence data, processed datasets, and code are archived with accessions ready. - [ ] Required collection/export permits and ethics approvals are documented. ## Common desk-reject triggers - A marker-development, primer, or genotyping-protocol note without an ecological or evolutionary question. - Descriptive population genotyping that reports structure or diversity statistics without testing a hypothesis or drawing ecological inference. - A study whose sampling design (too few populations, too few individuals) cannot support its demographic or selection claims. - A microbiome or eDNA dataset presented as a species/taxa list without ecological or evolutionary interpretation. - A genomics-heavy paper whose biological question is generic, post hoc, or weakly connected to the molecular results. ## Re-routing decision - Molecular-evolutionary or phylogenetic methodology and molecular-evolution theory at the core: Molecular Biology and Evolution (`molecular-biology-and-evolution`). - A conceptually broad eco-evolutionary advance of general significance beyond the molecular-ecology community: Nature Ecology & Evolution (`nature-ecology-and-evolution`). - A concise conceptual advance integrating theory and data: Ecology Letters (`ecology-letters`). - A primarily bioinformatic method or software tool: a methods venue (e.g., Methods in Ecology and Evolution, Molecular Ecology Resources). ## Output format ```text [Fit] High / Medium / Low (one-line reason) [Target] Molecular Ecology [Topic tags] <2–3 closest topics> [Method/evidence] [Top risk] [Official items to re-check]
