Resumo: | Environmental quality for jaguar, puma and ocelot in Guaratuba Bay, State of Paraná, using the programs Capture and Presence. Two month-long expeditions to Guaratuba Bay in the southern Atlantic Forest of Brazil were conducted in 2006. Parameters calculated from vestiges and camera-trap sampling were mammalian richness and proportion of area occupied (PAO) by jaguar, puma, and opportunistically, by ocelot. Eight quadrats 4km2 in size were sampled, over an area of 130km2, where fourteen species of mammals were recorded (CI(Nˆ )=14 to 14, CAPTURE). PAO was 25% for puma, and 100% for both jaguar and ocelot. It is argued that jaguar was expected to have capture probabilities similar to those of puma, as they both leave signs on open trails when present. The resulting PAO for jaguar is thus likely to be an artifact derived from low area fi delity and/or low density, rather than a product of the species’ low detection probability. This conjecture is substantiated by the reduced presence of important prey species in many of the sampling quadrats. The results do not diminish the importance of the study site for jaguar conservation; instead, these observations objectively identify the need to restore prey populations in the area. |

Parâmetros calculados a partir de amostragem de vestígios e armadilhas-fotográficas foram riqueza de espécies de mamíferos (1kg) e proporção de área ocupada(PAO) por onça-pintada, puma, e oportunisticamente, por jaguatirica. Oito qua- drantes de 4km2 foram amostrados, em uma área de 130km2, resultando em uma estimativa de 14 espécies de mamíferos (CI(Nˆ)=14 a 14, CAPTURE). PAO resultou em 25% para puma, e 100% tanto para a onça-pintada como para a jaguatirica. Argumenta-se que o esperado seria uma probabilidade de captura da onça-pintada similar a do puma, já que ambos deixam sinais em trilhas abertas quando presentes. O resultado de PAO para a onça-pintada é, portanto, considerado um artefato derivado de uma baixa fi delidade espacial e/ou baixa densidade, mais do que um produto da baixa detectabilidade da espécie. Esta conjectura é substanciada pela reduzida presença de importantes espécies-presa.Os resultados não diminuem a importância da área para a conservação da onça-pintada, ao invés disto, estas observações objetivamente identificam a necessidade de restabelecimento de populações de espécies-presa na área.Universidade Federal de Santa Catarina2008-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2008v21n2p10510.5007/2175-7925.2008v21n2p105Biotemas; v. 21 n. 2 (2008); 105-1172175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2008v21n2p105/18913Copyright (c) 2008 Marcelo Mazzolli, Matthias Ludwig Alfons Hammerinfo:eu-repo/semantics/openAccessMazzolli, MarceloHammer, Matthias Ludwig Alfons2018-03-07T18:12:52Zoai:periodicos.ufsc.br:article/20890Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2018-03-07T18:12:52Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
