Phylogenetic analysis suggests that the batrachian divergence occurred in the Middle Permian, rather than the late Carboniferous as recently estimated using molecular clocks18, 22, but the divergence with caecilians corresponds to the deep split between temnospondyls and lepospondyls, which is congruent with the molecular estimates.

For example, Keyfitz made the classification of the bifurcations in one state variable, without symmetry up to codimension 7; Golubitsky and Schaeffer obtained the classification of the bifurcation problems in one state variable with Z_2 symmetry, in one parameter up to codimension 3; Golubitsky and Roberts studied the classification of degenerate Hopf bifurcation in two state variables with dihedron D_4 symmetry, in one parameter up to topological codimension 2; Melbourne obtained the classification of bifurcations in three state variables with octahedral symmetry, in one parameter, up to

The model in this paper takes the form as belowThe main contents and results in this paper are as follows:In section 1, we state our main analytical results on equilibria of the above system. First, several sufficient conditions for coexistence of the steady-state are given by the standard fixed-point index theory in cone. Second, the global structure of the coexistence solutions and their local stability are established by using bifurcation theory. Third, the multiplicity, uniqueness and stability of positive steady-state solutions to this system are derived by means of perturbation theory of eigenvalues, standard regularity theory, Sobolev embedding theorem and fixed-point index theory.

By the analysis of the difference in the board before the Second Congress of the RSDLP, as well as the bifurcation between Martov and Lenin on the congress, I think the reason for Menshevik"s foundation is not their bifurcation on the problem of party member, but the difference between Martov and Lenin on the election of the RSDLP"s Central Committee and the editorial board of Iskra.

Thus, in every American deliberative assembly having no rules for conducting business, the motion to adjourn, when it does not dissolve the assembly, would be decided to be undebatable, as in Congress, the English parliamentary law to the contrary notwithstanding; so if the previous question were negatived, the debate upon the subject would continue, as in Congress, whereas in Parliament the subject would be immediately dismissed; so, too, the previous question could be moved when there was before the assembly a motion either to commit, or to postpone definitely or indefinitely, just as in Congress, notwithstanding that, according to English parliamentary law, the previous question could not be moved under such circumstances.
