Yet, empirical validation of these patterns has so far focused on less diverse taxa, with comparable assessments of mega-diverse groups historically constrained by the taxonomic impediment. Location: Global Time period: 2010-2017 Major taxa studied: Terrestrial arthropods Methods: Here we assess the temporal and spatial dynamics of arthropod communities using a beta-diversity framework, drawing on samples across 129 globally distributed monitoring sites. Overall, we encountered more than 150,000 unique barcode index numbers (BINs) (i.e. species proxies). We assessed between site differences in community diversity using beta-diversity and the partitioned beta-diversity components of species replacement (i.e. turnover) and richness difference (i.e. a measure of nestedness). Results: We show that global differences in community compositional change are linked to latitudinal, spatial, and temporal gradients. General global beta-diversity trends remained consistent across biogeographic regions, with beta-diversity (dissimilarity) increasing with decreasing latitude, greater spatial distance and greater temporal distance. By contrast, species replacement and richness difference patterns varied across biogeographic regions, suggesting different underlying processes are shaping regional biodiversity patterns. Latitudinal effects on species replacement or richness difference were significant for 3 out of 5 regions. Comparably we found significant spatial distance relationships with species replacement or richness difference for 3 out of 5 regions. Temporal distance was significantly associated with species replacement or richness difference for all 5 regions. Main conclusion: The general expectations of the latitudinal diversity gradient (LDG) are supported using a large, extensive global sampling effort. Our findings generally support the global LDG expectations, however, partitioned assessment of beta-diversity indicates the underlying processes driving the general global pattern, here species replacement and richness difference, may be regionally linked to differences in seasonality effects or variation in spatial distribution of environmental factors.

Yet, empirical validation of these patterns has so far focused on less diverse taxa, with comparable assessments of mega-diverse groups historically constrained by the taxonomic impediment.\u003c/p\u003e\n\u003cp\u003eLocation: Global\u003c/p\u003e\n\u003cp\u003eTime period: 2010-2017\u003c/p\u003e\n\u003cp\u003eMajor taxa studied: Terrestrial arthropods\u003c/p\u003e\n\u003cp\u003eMethods: Here we assess the temporal and spatial dynamics of arthropod communities using a beta-diversity framework, drawing on samples across 129 globally distributed monitoring sites. Overall, we encountered more than 150,000 unique barcode index numbers (BINs) (i.e. species proxies). We assessed between site differences in community diversity using beta-diversity and the partitioned beta-diversity components of species replacement (i.e. turnover) and richness difference (i.e. a measure of nestedness).\u003c/p\u003e\n\u003cp\u003eResults: We show that global differences in community compositional change are linked to latitudinal, spatial, and temporal gradients. General global beta-diversity trends remained consistent across biogeographic regions, with beta-diversity (dissimilarity) increasing with decreasing latitude, greater spatial distance and greater temporal distance. By contrast, species replacement and richness difference patterns varied across biogeographic regions, suggesting different underlying processes are shaping regional biodiversity patterns. Latitudinal effects on species replacement or richness difference were significant for 3 out of 5 regions. Comparably we found significant spatial distance relationships with species replacement or richness difference for 3 out of 5 regions. Temporal distance was significantly associated with species replacement or richness difference for all 5 regions.\u003c/p\u003e\n\u003cp\u003eMain conclusion: The general expectations of the latitudinal diversity gradient (LDG) are supported using a large, extensive global sampling effort. Our findings generally support the global LDG expectations, however, partitioned assessment of beta-diversity indicates the underlying processes driving the general global pattern, here species replacement and richness difference, may be regionally linked to differences in seasonality effects or variation in spatial distribution of environmental factors.\u003c/p\u003e","manuscriptTitle":"Global Arthropod beta-diversity is spatially and temporally structured by latitude","msid":"","msnumber":"","nonDraftVersions":[{"code":2,"date":"2023-09-22 21:06:46","doi":"10.21203/rs.3.rs-2180975/v2","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}},{"code":1,"date":"2022-10-27 13:08:36","doi":"10.21203/rs.3.rs-2180975/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"d37a919d-ec7e-4c6f-b99d-afdcd8cdcb35","owner":[],"postedDate":"September 22nd, 2023","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[{"id":24945708,"name":"Biological sciences/Ecology/Biodiversity"},{"id":24945709,"name":"Biological sciences/Ecology/Biogeography"},{"id":24945710,"name":"Biological sciences/Ecology/Molecular ecology"}],"tags":[],"updatedAt":"2024-05-09T00:37:15+00:00","versionOfRecord":{"articleIdentity":"rs-2180975","link":"https://doi.org/10.1038/s42003-024-06199-1","journal":{"identity":"communications-biology","isVorOnly":false,"title":"Communications Biology"},"publishedOn":"2024-05-08 00:37:14","publishedOnDateReadable":"May 8th, 2024"},"versionCreatedAt":"2023-09-22 21:06:46","video":"","vorDoi":"10.1038/s42003-024-06199-1","vorDoiUrl":"https://doi.org/10.1038/s42003-024-06199-1","workflowStages":[]},"version":"v2","identity":"rs-2180975","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-2180975","identity":"rs-2180975","version":["v2"]},"buildId":"7rjqhiLT3MXkJMwkYKINL","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
