Resumo: | As human civilizations developed and invested in technology, fishing became one of the greatest threats to marine ecosystems, impacting the ecological functions mediated by trait species. However, the exploitation of functional traits over time have never been assessed. Here we investigated the functional spectrum of marine vertebrate taxa exploited in south-southeast Brazilian coast in three different periods: the Shellmounds (8,720 – 230 years BP), the Colonial (1500 – 1966) and the Current period (1967 – 2015). A functional trait space analysis together with kernel density estimates revealed that the full spectrum of functional traits was fished over time. We identified 423 exploited taxa, of which 56 were exploited in all periods. Over time, fisheries have been functionally selective by targeting habitat specialists, invertivorous and macrocarnivorous taxa, with medium and large body size, benthopelagic and pelagic habits. Currently, fishing technology has boosted the capture of new traits far from the coast, such as planktivorous, sedentary, benthic, solitary, and small-bodied taxa. Fishing the entire functional trait spectrum clearly shows that fishing is an activity unsustainable over the centuries, and may be unfeasible in the future for two reasons: depletion of stocks and ecosystem functioning weakened by the poverty of traits. |

No entanto, a exploração de atributos funcionais ao longo do tempo nunca foi avaliada. Aqui investigamos a diversidade funcional de vertebrados marinhos explorados na costa sul-sudeste brasileira em três períodos distintos: Sambaquis (8.720 – 230 anos AP), Colonial (1500 – 1966) e Atual (1967 – 2015). Uma análise de espaços funcionais juntamente com estimativas de densidade de Kernel revelou que todo o espaço de atributos funcionais foi explorado ao longo do tempo. Identificamos 423 táxons pescados, dos quais 56 foram explorados em todos os períodos. Ao longo do tempo, a pesca tem sido funcionalmente seletiva, visando táxons com médio e grande tamanho corporal, especialistas de habitat, invertívoros e macrocarnívoros, hábitos bentopelágicos e pelágicos. Atualmente, a tecnologia de pesca tem impulsionado a captura de novos atributos longe da costa, como táxons de pequeno tamanho corporal, sedentários, bentônicos, solitários e planctívoros. A exploração de todo o espaço funcional mostra que a pesca é uma atividade insustentável ao longo dos séculos, podendo ser inviável no futuro por dois motivos: esgotamento dos estoques e enfraquecimento do funcionamento dos ecossistemas devido à perda de espécies e seus atributos.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em Biodiversidade AnimalUFSMBrasilCiências BiológicasAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessAbordagem baseada em atributosConservação marinhaDiversidade funcionalEcologia históricaExploração a longo prazoFauna marinhaFunctional diversityHistorical ecologyLong-term exploitationMarine conservationMarine faunaTrait-based approachCNPQ::CIENCIAS BIOLOGICASPescando funções: atributos funcionais explorados pela pesca através do tempoFishing functions: trait exploitation over timeinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisGomes, Mariana Benderhttp://lattes.cnpq.br/2822365334277282Herbst, Dannieli FirmeCarlucci, Marcos Bergmannhttp://lattes.cnpq.br/6221493668201729Ferreira, Bruna Ceretta2000000000066006006006006004ef3c20c-7319-4dbf-b5d0-6c58d61e014175cb7e8f-dc21-4446-9ed2-c719960ac93e0bc4d6a9-1e06-4c1e-a4a0-ef34556bfc0a024e63e7-8bbd-4546-bf3e-b806dec91ee6reponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGBA_2022_FERREIRA_BRUNA.pdfDIS_PPGBA_2022_FERREIRA_BRUNA.pdfDissertação de mestradoapplication/pdf1124555http://repositorio.ufsm.br/bitstream/1/27940/1/DIS_PPGBA_2022_FERREIRA_BRUNA.pdf0c6203fdfcea0bfecfcd63655d1caffeMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

As human civilizations developed and invested in technology, fishing became one of the greatest threats to marine ecosystems, impacting the ecological functions mediated by trait species. However, the exploitation of functional traits over time have never been assessed. Here we investigated the functional spectrum of marine vertebrate taxa exploited in south-southeast Brazilian coast in three different periods: the Shellmounds (8,720 – 230 years BP), the Colonial (1500 – 1966) and the Current period (1967 – 2015). A functional trait space analysis together with kernel density estimates revealed that the full spectrum of functional traits was fished over time. We identified 423 exploited taxa, of which 56 were exploited in all periods. Over time, fisheries have been functionally selective by targeting habitat specialists, invertivorous and macrocarnivorous taxa, with medium and large body size, benthopelagic and pelagic habits. Currently, fishing technology has boosted the capture of new traits far from the coast, such as planktivorous, sedentary, benthic, solitary, and small-bodied taxa. Fishing the entire functional trait spectrum clearly shows that fishing is an activity unsustainable over the centuries, and may be unfeasible in the future for two reasons: depletion of stocks and ecosystem functioning weakened by the poverty of traits. |
