Deforestation and forest fragmentation has been shown to have varying effects on biodiversity. In general, invertebrate diversity is expected to increase in the edge areas created by forest fragments. This study looked at the diversity of Hymenoptera in pasture, ecotone and secondary forest fragment in La Cruz to observe the effects of different habitats in diversity. The Shannon-Weiner diversity index values for pasture, ecotone and forest were 1.146, 1378 and 1.674 respectively, indicating highest diversity in the forest. Significant differences were found between the Shannon-Weiner diversity index comparisons (p <0.001).


Con mi proyecto estudio el efecto de la fragmentación del bosque para la biodiversidad. Observo Hymenoptera en La Cruz en Finca de Jim Wolfe 24 octubre – 8 noviembre, 2000. Quiero saber si hay diferencia en la diversidad Hymenoptera entre el potrero, el borde y el bosque. Colecto Hymenopteras con red para insectos, mientras estaba caminando diez metros en cada hábitat. Separe los Hymenopteras de las especies morpho y las envié a la Universidad de Costa Rica para identificación de familias. Con estadísticas determine que tiene más diversidad en el bosque que en otros hábitats.
