Uso Dos Isótopos Estáveis De Carbono, Nitrogênio E Enxofre Em Estudos De Ecologia Costeira

Abstract: RESUMOOs isótopos estáveis de carbono, nitrogênio e enxofre vêm sendo utilizados com sucesso para diversos fi ns em ecologia costeira. A maioria dos estudos tem se concentrado na elucidação de relações trófi cas em teias alimentares, em que têm-se empregado comumente os isótopos de carbono e nitrogênio, e às vezes os de enxofre. De forma similar, a determinação da origem da materia orgânica particulada na coluna d'água ou no sedimento de fundo tem sido bem sucedida com o uso de isótopos estáveis, notavelmente … Show more

“…Another mollusc, the golden mussel Limnoperna fortunei (Dunker, 1857), was introduced in the Paraná River 15 years ago and, due to its high biomass production, has become an important food resource for mammals, birds, and fish; therefore, the species has had a rather limited impact on the local fauna (Sylvester, Boltovskoy, & Cataldo, 2007). Human transport of this trout is considered to be a dispersal mechanism for the snail; economic activities related to fish farming should be monitored, especially since some programmes encourage release of the trout in parts of the continent (Lazzarotto & Caramaschi, 2009;MacCrimmon, 1971;Winckler-Sosinski, Silveira, Schulz, & Schwarzbold, 2008). Human transport of this trout is considered to be a dispersal mechanism for the snail; economic activities related to fish farming should be monitored, especially since some programmes encourage release of the trout in parts of the continent (Lazzarotto & Caramaschi, 2009;MacCrimmon, 1971;Winckler-Sosinski, Silveira, Schulz, & Schwarzbold, 2008).…”

“…The hydroclimatic model showed higher accuracy and higher val- America (Buenaño, 2010;Coradin & Tortato, 2006;Lasso, Machado-Allison, & Taphorn, 2016;Oporto & Latini, 2005) and occurs in some protected areas. Human transport of this trout is considered to be a dispersal mechanism for the snail; economic activities related to fish farming should be monitored, especially since some programmes encourage release of the trout in parts of the continent (Lazzarotto & Caramaschi, 2009;MacCrimmon, 1971;Winckler-Sosinski, Silveira, Schulz, & Schwarzbold, 2008). In Colombia, the rainbow trout has been established since 1926 (MacCrimmon, 1971), and has been recorded in the Cauca and Magdalena river basins, which together cover about 25% of the country and provide 11% of the water supply for its population (Cruz-Casallas, Medina-Robles, & Velasco-Santamaría, 2011).…”

“…(3) os valores isotópicos medidos em um consumidor devem refletir a assinatura de suas dietas (Peterson e Fry, 1987;Bearhop et al, 2004;Carvalho, 2008;Martinelli et al, 2009;Boecklen et al, 2011). Os isótopos mais empregados em estudos ecológicos são o de carbono ( 13 C/ 12 C) e o de nitrogênio ( 15 N/ 14 N).…”

“…Post (2002) (Post, 2002;Layman et al, 2007). Assim como o IRI é utilizado para caracterizar-se a dieta e a importância de diferentes itens alimentares na dieta de um predador através dos conteúdos gástricos, os modelos de mistura permitem que ele seja feito tendo como ponto de partida os valores isotópicos das presas e de seus respectivos consumidores (Carvalho, 2008 Gillespie (2013).

“…Além disso, a presença de peixes não-nativos predadores pode provocar o fenômeno de "Armadilha Evolutiva", ou seja, pela ausência histórica do novo predador no ambiente, espécies nativas são evolutivamente vulneráveis às espécies não-nativas predadoras (Schlaepfer et al 2002). Por exemplo, Oncorhynchus mykiss representa ameaça ao cascudo endêmico Pareiorhaphis garbei nas cabeceiras do rio Macaé, Rio de Janeiro (Lazzarotto & Caramaschi 2009). …”
