| oxygen consumption and the energetics of island-dwelling florida cottonmouth snakes. | we measured oxygen consumption (vo(2)) to estimate standard metabolic rates (smr) in cottonmouth snakes (agkistrodon piscivorus conanti) from seahorse key and the adjacent peninsula of northern florida. the island population is unusual because adult snakes feed on fish that are dropped by colonial nesting birds, and food resources are temporally limited relative to that of mainland populations. we found no differences in smr between island and mainland snakes at any of four experimental temperat ... | 2006 | 12024292 |
