{"doi":"10.1038/s41598-023-30652-6","title":"Drosophilids with darker cuticle have higher body temperature under light","abstract":"<jats:title>Abstract</jats:title><jats:p>Cuticle pigmentation was shown to be associated with body temperature for several relatively large species of insects, but it was questioned for small insects. Here we used a thermal camera to assess the association between drosophilid cuticle pigmentation and body temperature increase when individuals are exposed to light. We compared mutants of large effects within species (<jats:italic>Drosophila melanogaster ebony</jats:italic> and <jats:italic>yellow</jats:italic> mutants). Then we analyzed the impact of naturally occurring pigmentation variation within species complexes (<jats:italic>Drosophila americana/Drosophila novamexicana</jats:italic> and <jats:italic>Drosophila yakuba/Drosophila santomea</jats:italic>). Finally we analyzed lines of <jats:italic>D. melanogaster</jats:italic> with moderate differences in pigmentation. We found significant differences in temperatures for each of the four pairs we analyzed. The temperature differences appeared to be proportional to the differently pigmented area: between <jats:italic>Drosophila melanogaster ebony</jats:italic> and <jats:italic>yellow</jats:italic> mutants or between <jats:italic>Drosophila americana</jats:italic> and <jats:italic>Drosophila novamexicana,</jats:italic> for which the whole body is differently pigmented, the temperature difference was around 0.6 °C ± 0.2 °C. By contrast, between <jats:italic>D. yakuba</jats:italic> and <jats:italic>D. santomea</jats:italic> or between <jats:italic>Drosophila melanogaster Dark</jats:italic> and <jats:italic>Pale</jats:italic> lines, for which only the posterior abdomen is differentially pigmented, we detected a temperature difference of about 0.14 °C ± 0.10 °C. This strongly suggests that cuticle pigmentation has ecological implications in drosophilids regarding adaptation to environmental temperature.\n</jats:p>","journal":"Scientific Reports","year":2023,"id":14396,"datarank":0.5295773235270539,"base_score":2.772588722239781,"endowment":2.772588722239781,"self_citation_contribution":0.41588830833596724,"citation_network_contribution":0.11368901519108669,"self_endowment_contribution":0.41588830833596724,"citer_contribution":0.11368901519108669,"corpus_percentile":null,"corpus_rank":null,"citation_count":15,"citer_count":15,"citers_with_citation_signal":9,"citers_with_endowment":9,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":113893,"name":"Luis-Miguel Chevin","orcid":null,"position":1,"is_corresponding":false},{"id":113894,"name":"Philippe Christol","orcid":null,"position":2,"is_corresponding":false},{"id":113895,"name":"Sylvie Méléard","orcid":null,"position":3,"is_corresponding":false},{"id":113896,"name":"Michael Rera","orcid":null,"position":4,"is_corresponding":false},{"id":113897,"name":"Amandine Véber","orcid":null,"position":5,"is_corresponding":false},{"id":113898,"name":"Jean-Michel Gibert","orcid":null,"position":6,"is_corresponding":false},{"id":113892,"name":"Laurent Freoa","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":2.772588722239781,"endowment":2.772588722239781,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"36864153","pmcid":"PMC9981618","openalex_id":"https://openalex.org/W4323037479","authors":[],"funders":[{"funder_name":"chair program Mathematical Modelling and Biodiversity","grant_id":"","title":null},{"funder_name":"CNRS Mission for Transversal and Interdisciplinary Initiatives","grant_id":"","title":null}],"total_grants":2,"fwci":4.3496,"citation_percentile":0.94504139,"influential_citations":2,"citation_trend":[{"year":2024,"count":5},{"year":2025,"count":9},{"year":2026,"count":1}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://www.nature.com/articles/s41598-023-30652-6.pdf","host_type":"journal"},{"url":"https://www.nature.com/articles/s41598-023-30652-6.pdf","host_type":"GOLD"},{"url":"https://www.nature.com/articles/s41598-023-30652-6.pdf","host_type":"publisher"},{"url":"https://www.nature.com/articles/s41598-023-30652-6","host_type":"publisher"},{"url":"https://doi.org/10.1038/s41598-023-30652-6","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/36864153","host_type":"repository"},{"url":"https://hal.science/hal-04014031","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/9981618","host_type":"repository"},{"url":"https://hal.science/hal-04183517/document","host_type":"repository"},{"url":"https://doaj.org/article/0d38047c1d3f47a3a8008669a6e7dd3b","host_type":"repository"},{"url":"https://hal.science/hal-04014031/document","host_type":"repository"},{"url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC9981618/pdf/41598_2023_Article_30652.pdf","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC9981618","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC9981618?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["Insect and Arachnid Ecology and Behavior","Neurobiology and Insect Physiology Research","Insect Utilization and Effects","Medicine","Biology","Environmental Science","Animals","Body Temperature","Drosophila melanogaster","Fever","Drosophila","Pigmentation","Diospyros"],"mesh_terms":["Animals","Body Temperature","Drosophila","Drosophila melanogaster","Fever","Pigmentation","Diospyros"],"keywords":["Drosophila melanogaster","Drosophila (subgenus)","Cuticle (hair)","Biology","Drosophilidae","Mutant","Melanogaster","Zoology","Anatomy","Genetics","Gene"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life in Land"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-01T09:25:39.596845Z","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":[]}
