Bald-faced hornet hydrocarbons serve as a barrier to moisture diffusion and thus prevent dehydration in wasps. Cuticular hydrocarbon profiles vary over species and nests, and so cuticular hydrocarbons are a proposed mechanism for nest-mate recognition. Worker and queen cuticular lipids have similar components, but their distributions differ dramatically, implying that cuticular hydrocarbons also play a role in caste differentiation. The following lipid profiles were determined from specimens collected in the summer and early fall of northeastern Georgia in 1989. The dominant hydrocarbons recovered from the cuticles of workers were n-alkanes and methyl branched and dimethyl branched alkanes with a C27 or a
Bald Mountain (New York) Bald Mountain (New York) Bald Mountain, or Rondaxe Mountain, is a part of the Adirondack Mountains in the U.S. state of New York. The trail leading up the mountain is a popular hike, likely due to its proximity to tourist towns (such as Old Forge, NY). The mountain is also home to the Rondaxe Mountain Fire Tower, which contributes to the trail's popularity. Bald Mountain was used by Verplanck Colvin in the 1870s as a survey point. Colvin suggested in 1886 that the summit take the name "Mt. St. Louis". Bald Mountain is the name most commonly used today, but
