Abstract In 2016, day butterflies were tracked in order to establish the importance of 33 edge effects (EB) formed by three traditional agroforestry systems immersed in a fragmented mesophilic forest in Xochitla, Mixtla de Altamirano, Veracruz. Systematic sampling and counting in points with fixed radius were established: the analyzes were carried out by: A) families with EB; B) subfamilies with EB; C) families by sampling; and D) subfamilies by sampling. Wealth and relative abundance were assessed using Jacknife1 and diversity with Shannon-Wiener. Kruskal-Wallis for the three indices, Cluster (wealth and abundance) and X2 (abundance). Jacknife1 showed values: 70.62; 47.6; 96.66, 80.27%. There were no differences: F= 16, p= 0.724; F= 9, p= 0.4966; F= 20, p= 0.6584; F= 13, p= 0.5953. Cluster exhibited 3 to 5 amalgamations. The IAR presented minimum-maximum average values of 0.001-0.578. There were no discrepancies: F= 26, p= 0.5642; F= 20, p= 0.6271; F= 22, p= 0.8414; F= 30, p= 0.4376. Cluster exhibited 3 to 5 amalgamations. X2 manifested values: p= 0.5396, p= 0.7577, p= 0.5708, p= 0.3083. Shannon-Wiener exhibited values: H’= 1.38; H’= 2.4; H’= 1.49; H’= 2.49. In two cases there were no differences: F= 3, p= 0.2839; F= 3, p= 0.2839; however, in two if: F= 5, p= <0.0003; F= 11, p= <0.0015. Results are shown, respectively for A, B, C, D. The parameters under study of diurnal butterflies in the considered EB were estimated-compared, this lays the basis for future research of Lepidopterofauna in agroforestry and EB systems for this particular region from Veracruz.
Resumen En el año 2016 se realizó el seguimiento de mariposas diurnas con el objeto de establecer la importancia de 33 efectos de borde (EB) conformados por tres sistemas agroforestales tradicionales inmersos en un bosque mesófilo fragmentado en Xochitla, Mixtla de Altamirano, Veracruz. Se estableció muestreo sistemático y recuento en puntos con radio fijo: Los análisis se realizaron por: A) familias con EB; B) subfamilias con EB; C) familias por muestreo; y D) subfamilias por muestreo. La riqueza y abundancia relativa se evaluaron mediante Jacknife1 y la diversidad con Shannon-Wiener. Kruskal-Wallis para los tres índices, Clúster (riqueza y abundancia) y X2 (abundancia). Jacknife1 mostró valores: 70.62; 47.60; 96.66, 80.27%. No existieron diferencias: F= 16, p= 0.724; F= 9, p= 0.4966; F= 20, p= 0.6584; F= 13, p= 0.5953. Clúster exhibieron de 3 a 5 amalgamaciones. El IAR presentó valores promedios mínimos-máximos de 0.001-0.578. No existieron discrepancias: F= 26, p= 0.5642; F= 20, p= 0.6271; F= 22, p= 0.8414; F= 30, p= 0.4376. Clúster exhibieron de 3 a 5 amalgamaciones. X2 manifestó valores: p= 0.5396, p= 0.7577, p= 0.5708, p= 0.3083. Shannon-Wiener exhibió valores: H’= 1.38; H’= 2.4; H’= 1.49; H’= 2.49. En dos casos no hubo diferencias: F= 3, p= 0.2839; F= 3, p= 0.2839; sin embargo, en dos si: F= 5, p= <0.0003; F= 11, p= <0.0015. Se muestran resultados, respectivamente para A, B, C, D. Se estimaron-compararon los parámetros bajo estudio de mariposas diurnas en los EB considerados, la presente sienta las bases para futuras investigaciones de la Lepidopterofauna en sistemas agroforestales y EB para esta región particular de Veracruz.
