Change in Entomofauna Composition Across a Forest-Filed Transition and Kortright Conservation Area

Résumé

Forest fragmentation is becoming increasingly common in today’s anthropocentric world, pushing the study of ecotones and their interactions to the forefront of conservation biology. For this study, arthropods—ideal organisms for studying the environment—were sampled along three field-forest transitions at the Kortright Conservation Area in Woodbridge, Ontario (Canada) in order to investigate any changes in mean ordinal diversity or abundance. Various capture techniques are also examined in order to determine overall effectiveness. Results show that there is not a significant change in mean ordinal diversity over distance. However, there is a statistically significant negative linear relationship between arthropod abundance and distance. Results also show that yellow pan traps are the most effective method for capturing arthropods in this setting. This indicates that grasslands should be of primary concern when formulating a conservation strategy plan directed at arthropod biodiversity, and that painted pan traps are very important tools for entomological sampling.
