Resumo: Aquatic food webs have been especially impacted in the last thirty years. This is particularly true for trophic webs with Mobile Generalist Species (MGS), which are species with high mobility (movement and dispersal) and flexibility in both foraging and habitat use. In general, MGS are large-sized species with the ability to move long distances, and they may be top predators (Large Generalist Predator; LGP) or feed lower in the food web than predicted from their size (Giant Secondary Consumers; GSCs). These species groups will play a fundamental role in connecting and rewiring human-impacted food webs, however this may be challenging because the stream network connectivity in most of the world’s largest river basins has been severely fragmented by dams

Isto ocorre em especial para teias tróficas com Espécies Generalistas Viajantes (MGS) que são espécies com alta mobilidade (movimento e dispersão) e flexibilidade em forrageamento e uso do habitat. Em geral, MGS são espécies de grande tamanho com habilidade de se mover longas distâncias como predadores de topo (Grande Predador Generalista, LGP) ou de se alimentar em estratos mais baixos da teia trófica do que o predito pelo seu tamanho, são espécies chamadas Consumidoras Secundárias Gigantes (GSC). Estes grupos de espécies terão papel fundamental em conectar e reestruturar as teias tróficas impactadas pelo homem. Entretanto, isto pode ser um desafio devido ao fato que as conectividades das redes hidrográficas nas maiores bacias do mundo têm sido severamente fragmentadas por barramentosAssociação Brasileira de LimnologiaAttribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/info:eu-repo/semantics/openAccessReservatóriosImpacto de hidrelétricasPredadores de topoPirâmide tróficaReservoirHydropower impactTop predators;Trophic pyramidAquatic food webs will need to stand on giants’ shouldersTeias tróficas aquáticas precisarão se apoiar sobre os ombros dos gigantesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleengreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNORIGINALAquaticFoodWebs_ANGELINI_2019.pdfAquaticFoodWebs_ANGELINI_2019.pdfapplication/pdf617675https://repositorio.ufrn.br/bitstream/123456789/30593/1/AquaticFoodWebs_ANGELINI_2019.pdff84d1b5d36c6eb0d657725328b1cc49eMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8914https://repositorio.ufrn.br/bitstream/123456789/30593/2/license_rdf4d2950bda3d176f570a9f8b328dfbbefMD52LICENSElicense.txtlicense.txttext/plain; charset=utf-81484https://repositorio.ufrn.br/bitstream/123456789/30593/3/license.txte9597aa2854d128fd968be5edc8a28d9MD53TEXTAquaticFoodWebs_ANGELINI_2019.pdf.txtAquaticFoodWebs_ANGELINI_2019.pdf.txtExtracted texttext/plain16697https://repositorio.ufrn.br/bitstream/123456789/30593/4/AquaticFoodWebs_ANGELINI_2019.pdf.txt527477704661adaa787ecf30aa8cfd0cMD54THUMBNAILAquaticFoodWebs_ANGELINI_2019.pdf.jpgAquaticFoodWebs_ANGELINI_2019.pdf.jpgGenerated Thumbnailimage/jpeg1515https://repositorio.ufrn.br/bitstream/123456789/30593/5/AquaticFoodWebs_ANGELINI_2019.pdf.jpgb9dc8273b8019c8f619eee2c7491719aMD55123456789/305932020-11-22 04:54:08.348oai:https://repositorio.ufrn.br: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Repositório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2020-11-22T07:54:08Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false
