Abstract Pocket gophers (Geomys pinetis), Gopher Tortoises, armadillos, and fire ants were
the primary soil disturbance agents in a longleaf pine ecosystem. Pocket gopher mounds …

Sea-level rise and frequent intense hurricanes associated with climate change will result in
recurrent flooding of inland systems such as Gulf Coastal pitcher plant bogs by storm surges …

Mounds formed by pocket gophers (Geomys pinetis) in a longleaf pine—wiregrass savanna
had larger daily soil temperature fluctuations than surrounding matrix locations. Microsite …
