| physiology of common map turtles (graptemys geographica) hibernating in the lamoille river, vermont. | common map turtles (graptemys geographica) were collected from a natural underwater hibernaculum in vermont at monthly intervals during the winter of 1997-1998. blood was sampled by cardiac puncture and analyzed for ph, pco(2), po(2), and hematocrit; separated plasma was tested for na(+), k(+), cl(-), total [ca], total [mg], [lactate], and osmolality (mosm kg(-1) h(2)o). control (eupneic; 1 degrees c) values for ph, po(2), pco(2), [hco(3)(-)], and [lactate] were 7.98 +/- 0.03, 47.4 +/- 18.7, 10. ... | 2000 | 10617856 |
| map turtle winter leech loads. | adult common map turtles, graptemys geographica (n = 243), were obtained in november 1995 from a hibernation site in the lamoille river, vermont. of the 208 female turtles examined, 151 (72.6%) had at least 1 leech (placobdella parasitica) attached and 10 of 35 males (28.6%) were similarly parasitized. mean abundances were 1.49 (sd = 1.461, n = 208) for female turtles and 0.34 (sd = 0.591, n = 35) for males; the difference was significant (t = 4.558, df = 241, p < 0.001). leech broods were found ... | 1997 | 9406801 |
