Influência do tamanho da amostra na estimativa da riqueza em espécies em levantamentos de abelhas silvestres (Hymenoptera, Apoidea)

Abstract: The effect of area size, number of collecting hours and months surveyed, on the estimation of relative richness of bees is analized. In order to characterize a biogeographical region, it is suggested to collect various samples of no less than 400 especimens for each one, in contrasting localities within a region, utilizing the usual standardized methodology for wild bees collecting. Thus, it is possible to have a better profit of the effort invested in the survey, making it possible to… Show more

“…Comparative analyses among faunas from different places are usually hindered because of the differences in the sampling intensity, sampling period, area size and the type of habitat studied (Heithaus 1979, Cure et al 1990). However, qualitative and quantitative comparisons of studied faunas that used similar methodologies can supply information about possible richness and abundance patterns for communities from the same ecosystem type, ecotone zones or different ecosystems (Silveira & Campos 1995, Viana et al 1997, Neves & Viana 2002).…”

“…Due to the low temperatures registered between the months of May and August, with consequent reduction of flowering plants and bee activity, these months were not sampled in 2007. The option of not performing collections during the cold months followed the work of Cure et al (1991). These authors state that reliable estimates of relative bee richness can be performed from partial samplings involving only the months of greater activities of these insects.…”

“…Almeida (2002) e Andena (2002) estudando a comunidade de abelhas no cerrado de outros municípios do Estado de São Paulo encontraram a mesma proporção. A família Apidae também apresentou maior abundância em outras formações vegetais, como a caatinga (MARTINS, 1990;CAVALHO, 1999), campos rupestres (FARIA; CAMARGO, 1996) e pastagem abandonada (CURE et al, 1993;SILVEIRA et al, 1993 (LAROCA , 1974;HEITHAUS, 1979;CURE-HAKIM, 1983;CAMPOS, 1989;LAROCA, 1990;ZANELLA, 1991;PEDRO, 1992;BARBOSA;LAROCA, 1993;MATEUS, 1998;CARVALHO, 1999). Segundo Andena (2002) este padrão é típico de ecossistemas tropicais.…”
