Abstract

Biofuels have become a key source for fuel globally as we move away from fossil fuel use. The US has created mandates which seek to increase fuel produced from biofuels, and the Southeast is a prime source area for biofuel development. Land use change required for increased biofuel cultivation may have negative impacts on biodiversity. This study explores how one critical component of diversity, bees, will be impacted. I observe bees' interactions with flowering plants via changes in pollen carrying behavior within a variety of conditions resulting from traditional vs biofuels-oriented practices concerning pine plantations. I used pollen carrying behavior to understand: 1) If bees were foraging for food successfully and 2) If bees were pollinating plants successfully. I found that open area conditions promoted high foraging success with low pollination success while covered area conditions promoted low foraging success with high pollination success. By implementing a biofuels regime to meet fuel needs, alternating states of poor foraging for bees and poor flowering plant reproduction will result. This will lead to a decline in reproduction for both bees and pollinator-dependent plants.
