Previous issue date: 2017-03-17 / Funda??o de Amparo ? Pesquisa do Estado da Bahia - FAPEB / This work has aimed to evaluate the size and shape of the wing of individuals of three Euglossini bee species (Euglossa cordata (Linnaeus, 1758), Euglossa ignita Smith, 1874 and Eulaema atleticana Nem?sio, 2009). For that, geometric morphometrics methods, as well as landscape metrics, were used for such evaluation. The analyzed specimens were collected in five areas, being four forest areas and one area of Agroforestry System (SAF). Morphometric analyzis were started with the right wing photograph of the individuals of each species and with the determination of anatomical landmarks and semilandmarks. Subsequently, the Cartesian coordinates obtained were used for analysis of variance of the shape and size of the wing of the populations. The results of the shape analysis were significant for the three species (p<0.05) and demonstrated that the individuals collected within the SAF area have had the greatest divergences in the shape of the wing. On the other hand, size differences were significant only for the populations of E. ignita (ANOVA: F = 5.923 and p = 0.00045). For E. cordata and El. Atleticana, there has been a significant correlation between morphometric data and landscape metrics (r<0.05), which shows a close relationship between these species and the forest cover. Thus, the present work underlines the importance of Euglossini bees in environmental quality monitoring studies, since morphometrics differences may reveal the existence of environmental stress. / Este trabalho teve como objetivo avaliar o tamanho e a forma da asa de indiv?duos de tr?s esp?cies de abelha Euglossini (Euglossa cordata (Linnaeus, 1758), Euglossa ignita Smith, 1874 e Eulaema atleticana Nem?sio, 2009) em resposta ? estrutura da paisagem. Assim, as abelhas foram coletadas em quatro fragmentos florestais com marcante influ?ncia antr?pica e numa ?rea de sistema agroflorestal(SAF). Para tal avalia??o, utilizou-se m?todos de morfometria geom?trica, bem como m?tricas da paisagem. As an?lises morfom?tricas iniciaram com a fotografia da asa direita dos indiv?duos de cada esp?cie e com a determina??o de marcos e semimarcos anat?micos. Posteriormente, as coordenadas cartesianas obtidas foram utilizadas para an?lise de vari?ncia da forma e do tamanho da asa das popula??es. Os resultados da an?lise de forma foram significativos (p<0.05) para as tr?s esp?cies e demonstraram que os indiv?duos coletados dentro da ?rea de SAF possuem as maiores diverg?ncias na forma da asa. Por sua vez, as diferen?as de tamanho foram significativas apenas para as popula??es de E. ignita (ANOVA: F= 4,557 e p= 0,001801. Para E. cordata e El. atleticana, houve correla??o significativa entre dados morfom?tricos e as m?tricas da paisagem (r<0.05), o que demonstra uma estreita rela??o destas esp?cies com a cobertura florestal. Assim, o presente trabalho salienta a import?ncia das abelhas Euglossini nos estudos de monitoramento de qualidade ambiental, uma vez que diferen?as morfom?tricas podem revelar a exist?ncia de stress ambiental.
