Resumo: | (SPATIAL VARIATIONS IN INTERACTION NETWORKS OF PLANTS AND FLOWER VISITORS AT MULTIPLE SCALES) Most studies on interactions between plants and flower visitors with a network approach are descriptive and lack empirical tests of their properties. Although many studies point out that communities of animals and plants respond to habitat variations and to landscape characteristics, there are still a few evidences that demonstrate the effect of these factors on interaction networks. Aiming at investigating factors that explain spatial variation in networks of visitors and flowers, I selected 15 sampling units of 0.25 ha, from 1.5 km to 8.0 km apart from each other, in the surroundings of Parque Municipal de Mucugê (12°59'18"S and 41°20'22"W), Chapada Diamantina, Bahia, where the dominant vegetation is composed of rocky fields intercalated with Cerrado patches, and the regional climate is tropical semi-humid. The plants and their visiting species were sampled in March, April and May (main flowering period), totalizing a sampling effort of 33 hours/area. Using visit data, I built local interaction networks, described with the following parameters: number of vertices, number of links, diameter, number of components, average shortest path, centralization, degree of nestedness and degree of agglomeration. Sampling units were described according to their habitat characteristics, similarity of floral resources, similarity of flower visitor communities, vegetation type, distance between sampling units and landscape characteristics (obtained from the characterization of the surroundings of each unit in buffers of 250, 500 and 750 m, based on a Ikonos satellite image with 1-m resolution, and using parameters of composition and configuration). Using a principal component analysis (PCA) I extracted explanatory axes for network, habitat and landscape parameters. In order to test for the association between explanatory factors and network characteristics I estimated correlations with adjusted significance levels. None of the factors analyzed showed a significant relationship with the network properties. Hence, results indicate that even if communities vary spatially, their network properties are constant. Those findings advanced knowledge in this field and may be important for conservation. |

Diversos trabalhos apontam que as comunidades de animais e plantas respondem a variações de habitat e ao contexto da paisagem, no entanto, ainda são poucas as evidências que demonstram o efeito desses aspectos sobre as redes de interações. Visando investigar fatores explicativos para a variação espacial das redes de interações de visitantes e flores, foram selecionadas 15 unidades amostrais de 0,25ha, distando de 1,5km a 8,0km, no entorno do Parque Municipal de Mucugê (12°59'18"S e 41°20'22"W), Chapada Diamantina, Bahia, onde predomina a vegetação do tipo campo rupestre intercalada por áreas relictuais de cerrado, e clima tropical semi-úmido. As plantas e suas espécies visitantes foram inventariadas nos meses de março, abril e maio (período de maior intensidade de floração), totalizando esforço amostral de 33 horas/área. A partir dos dados de visitação foram obtidas as redes de interações locais, caracterizadas quanto ao n° de vértices, n° de arestas, diâmetro, n° de componentes, caminho mínimo médio, centralização, grau de aninhamento e grau de aglomeração. As unidades amostrais foram caracterizadas quanto às suas características do habitat, similaridade dos recursos florais, similaridade das comunidades de visitantes florais, tipo de fitofisionomia, distância entre as unidades, e características da paisagem (obtidas a partir da caracterização do entorno de cada unidade em buffers de 250, 500 e 750m, a partir de imagem IKONOS com resolução de 1m, por parâmetros de composição e de configuração). Através da análise de componentes principais (PCA), foram extraídos os eixos explicativos para os parâmetros de rede, de habitat e de paisagem, e para verificação de associação entre os possíveis fatores explicativos e as características das redes foram realizados testes de correlação, com o nível de significância ajustado. Nenhum dos fatores investigados apresentou relação significativa com as propriedades das redes, de modo que talvez esses resultados sejam um indicativo de que mesmo que as comunidades variem espacialmente, as propriedades das redes se mantêm, o que pode ser uma informação importante para a conservação, uma vez que constitui um avanço nesse campo do conhecimento.Submitted by Bruno Matos Nascimento (brunomatos@uefs.br) on 2020-06-05T20:09:06Z No. of bitstreams: 1 TESE_CAMILA MAGALHÃES PIGOZZO.pdf: 39966188 bytes, checksum: 60ce488311112f708bffcc5611ffdd80 (MD5)Made available in DSpace on 2020-06-05T20:09:06Z (GMT).
