| isotopic evidence for methane-based chemosynthesis in the upper floridan aquifer food web. | anecdotal observations of the dougherty plain cave crayfish (cambarus cryptodytes), the georgia blind cave salamander (haideotriton wallacei), and albinistic isopods (caecidotea sp.) at great depths below the land surface and distant from river corridors suggest that obligate aquifer-dwelling (troglobitic) organisms are widely distributed throughout the limestone upper floridan aquifer (ufa). one mechanism by which subterranean life can proliferate in an environment void of plant productivity is ... | 2006 | 16862438 |
