Arthropods of Moon Woods


My Biological Diversity class (BIO 106) collected 8 species of ants in Moon Woods, which is slightly less than the 9 species we collected (with equal sampling intensity) at other forested sites on campus.   (Although we did not collect any fire ants in Moon Woods, they are almost certainly present, albeit in low density.)  The ant community in Moon Woods is more typical of one in undisturbed woodlands, with three species of Camponotus and one ponerine.  Disturbed sites, such as a clear cut on Lavender Mountain and the Victory Lake Basin, had ant communities dominated by Solenopsis invicta and Paratrechina vividula.

Carabid beetles are often useful indicators of disturbance.   We only collected one species of carabid beetle in Moon Woods.  Some of our other sites on campus had as many as 5 species of carabids.

Notably absent from our pitfall samples were scorpions (Vejovis carolinianus), daddy longlegs (2 species of Opiliones), and several millipedes (Polydesmida and Spirobo).  These are all very common in forests on the Mountain Campus.
 

Figure 1.  Wet weight of arthropods from pitfall traps in Moon Woods is approximately the same as that for other forested sites on campus, such Martha's Meadow (near Victory Lake Basin) and Upland Forest near the Old Mill.  Forested sites had considerably less wet biomass than an Upland Clear Cut and Victory Lake Basin.
