 | | Use of terrestrial habitats by amphibians in the sandhill uplands of north-central Florida. |  | | In North America, many amphibians have a biphasic life cycle consisting of an egg and larval stage in water, metamorphosis into a terrestrial adult, and remigration back to water as adults to breed and lay eggs. |  | | In certain instances, it may be desirable to inventory amphibians using specialized techniques, such as by employing traps (e.g., soft or hard minnow traps), coverboards, PVC pipe, debris bags (Pauley and Little, 1998) or drift fences with pitfalls. |

| | Siren, the Amphibian - Waterman and Hill-Traveller's Companion |
 | | Sirens are generalists when it comes to feeding and can survive on a large size-range of food ranging from microscopic organisms which they filter feed to large creatures like small fish, dragonfly larvae and crayfish. |  | | Sirens, like most salamanders in our area, don't hibernate since they're active as long as their ponds remain full, even when covered with ice. |  | | They have a pair of small front legs which they use to pull themselves through their weedy, murky world - and no hind legs - and unlike any other salamander each of their four toes ends in a claw or toenail which on a salamander is a very odd thing indeed. |

| | Use of Amphibians as Indicators of Ecosystem Restoration Success |
 | | The siren in the trap was transferred to the bucket to be measured, weighed, and permanently marked using a microchip transponder. |  | | Amphibians are found in virtually all habitats from pine forests to sawgrass marshes to mangrove estuaries, and they can become extremely abundant locally. |  | | Another major impact on amphibians in the Everglades may be the introduction of invasive species. |

| | Greater siren : Siren lacertina |
 | | The common name "greater" comes from the fact that the other species in the genus, the Lesser Siren (Siren intermedia) measures less than 2 feet in total length, in contrast to the "greater" sirens which can exceed 3 feet in length. |  | | They feed primarily on aquatic invertebrates, such as crustaceans and insect larvae. |  | | One female may lay up to 1400 eggs a year. |
