Resumo: | Natural landscapes have been dramatically affected by habitat loss and fragmentation, which transform continuous forest in habitat patches imbedded in areas of non-habitat (matrices). This matrices, inhospitable or not, affect countless ecological process, like dispersal. One of the ways to understand this effect of matrix on dispersal is studying animal’s perceptual range. Which is a range at which an animal perceive landscape elements. This perception is directly connected to the success to reach a new habitat patch while animals navigate through matrix. To contribute to this knowledge we evaluate the habitat perception of Heliconius erato. However, we were also interest in evaluate the effect of butterflies age and matrix type on its perception. Consequently, we raised butterflies on laboratory and matched with butterflies from forest during a release experiment. To determinate perceptual range, we did releases in two different matrices at three distances from forest (0, 30 and 100 meters) and measured the final angle reached for butterflies. We found that: I) butterflies released in edge were strongly oriented to forest; II) than higher the release distance the lower perceptual ability and III) there is an interaction between age and matrix type. Naïve butterflies oriented better on open field (perceptual range: 30-100 meters and experienced oriented better at coconut plantation (perceptual range: 30-100 meters). |

Essas matrizes, inóspitas ou não, afetam incontáveis processos ecológicos, como a dispersão. Uma das formas de compreender o efeito da matriz no processo de dispersão é estudando o alcance da percepção do habitat dos animais, o qual é definido como o alcance (distância) em que um animal pode perceber elementos da paisagem. Essa percepção está diretamente relacionada ao sucesso de chegada à um novo habitat, enquanto o animal navega por uma matriz. Nós avaliamos a percepção do habitat em Heliconius erato, uma borboleta tropical. Entretanto nós também estávamos interessados em avaliar o efeito da idade das borboletas e do tipo de matriz na percepção do habitat. Consequentemente, nós criamos borboletas em laboratório e pareamos com borboletas coletadas na floresta durante um experimento de soltura. Para determinar o alcance da percepção, nós realizamos solturas em duas diferentes matrizes (coqueiral e campo em regeneração) à três distâncias da floresta (0,30 e 100 metros) e medimos o ângulo final alcançado pelas borboletas. Nós encontramos que (I) borboletas soltas na borda se orientaram fortemente para a floresta; (II) quanto maior a distância de soltura, menor a habilidade de perceber o habitat e (III) há interação entre matriz e idade da borboleta. Borboletas inexperientes se orientaram melhor no campo aberto (alcance da percepção: 30-100 metros) e experientes se orientaram melhor no coqueiral (alcance da percepção entre 30-100 metros).porUniversidade Federal do Rio Grande do NortePROGRAMA DE PÓS-GRADUAÇÃO EM ECOLOGIAUFRNBrasilCNPQ::CIENCIAS BIOLOGICAS::ECOLOGIAHabitat fragmentationNaïveButterflyHeliconius eratoPerceptual rangeFinding the way home: movement of butterflies in non-familiar habitatsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNORIGINALFindingWayHome_Morais_2015.pdfFindingWayHome_Morais_2015.pdfapplication/pdf1108230https://repositorio.ufrn.br/bitstream/123456789/20505/1/FindingWayHome_Morais_2015.pdf991dd1219cb6612e1e50a7f59e2672aaMD51TEXTVanessaRodriguesDeMorais_DISSERT.pdf.txtVanessaRodriguesDeMorais_DISSERT.pdf.txtExtracted texttext/plain43773https://repositorio.ufrn.br/bitstream/123456789/20505/6/VanessaRodriguesDeMorais_DISSERT.pdf.txt0d62e7e27105ccd560ffda4ae6791b8fMD56FindingWayHome_Morais_2015.pdf.txtFindingWayHome_Morais_2015.pdf.txtExtracted texttext/plain43744https://repositorio.ufrn.br/bitstream/123456789/20505/8/FindingWayHome_Morais_2015.pdf.txta5e92a7faeffb1212aa2adb7d4a92025MD58THUMBNAILVanessaRodriguesDeMorais_DISSERT.pdf.jpgVanessaRodriguesDeMorais_DISSERT.pdf.jpgIM Thumbnailimage/jpeg2660https://repositorio.ufrn.br/bitstream/123456789/20505/7/VanessaRodriguesDeMorais_DISSERT.pdf.jpg5290ca0115e830a76cde738c4c9893ffMD57FindingWayHome_Morais_2015.pdf.jpgFindingWayHome_Morais_2015.pdf.jpgGenerated Thumbnailimage/jpeg1282https://repositorio.ufrn.br/bitstream/123456789/20505/9/FindingWayHome_Morais_2015.pdf.jpgba37f5e6009407e6ef3be5526bcbed77MD59123456789/205052019-06-02 02:18:31.957oai:https://repositorio.ufrn.br:123456789/20505Repositório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2019-06-02T05:18:31Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false |
