| motor control of tongue movement during prey capture in plethodontid salamanders | four species of salamander of the family plethodontidae were examined using electromyographic (emg) recording during prey-capture behavior to test the hypotheses that the tongue retractor, tongue protractor and jaw depressor muscles are activated simultaneously and in a stereotyped pattern, as was found in other salamanders, and to determine whether species with different tongue morphologies and tongue protraction abilities exhibit different motor control strategies. the results show that sequen ... | 1999 | 10574747 |
| a centromeric satellite dna in the european plethodontid salamanders (amphibia, urodela). | a highly repeated satellite dna (hy500) located in the centromeric heterochromatin of the european plethodontid salamander speleomantes (formerly hydromantes) was studied. the hy500 family represents about 1% of the speleomantes supramontis genome and has a major repeating unit of about 500 base pairs, which may have evolved from the progressive amplification of shorter sequences. this centromeric satellite is conserved in all the speleomantes species, which nevertheless show distinct patterns o ... | 1991 | 1778466 |
