  We report on magnetoconductance measurements through a weakly coupled quantum
dot, containing roughly 900 electrons, in a wide magnetic field range from 0 T
to 12 T. We find modulations of the conductance resonances in the quantum Hall
regime for higher integer filling factors $6> \nu_\mathrm{dot} > 2$, in
addition to modulations at $2> \nu_\mathrm{dot} > 1$ and at fractional filling
factors $\nu_\mathrm{dot} \gtrsim 2/3$, $1/3$. Depending on the internal
filling factor, edge reconstruction inside the quantum dot leads to the
formation of multiple concentric compressible regions, which contain discrete
charge and are separated by incompressible rings. Quasiparticle tunneling
between different compressible regions results in
magnetic-field-(pseudo)-periodic modulations of the Coulomb resonances with
different periodicities, additional super-periodicity or non-periodic features.
The evolution of the period in magnetic field indicates cyclic depopulation of
the inner compressible regions close to integer filing factors. We study the
temperature dependence of the conductance resonances for different magnetic
fields. While at low fields, the resonance amplitude decays inversely with
temperature, corresponding to single-level transport, the temperature
dependence of the amplitude evolves continuously into a linearly increasing
behavior for dot filling factor $2> \nu_\mathrm{dot} > 1$. This coincides with
a reduction of the charging energy by approximately a factor of 2 in the same
regime. At zero magnetic field, the temperature dependence differs for
individual resonances, and is found to depend on the closeness to quantum dot
states that couple strongly to the leads. The presented experiments complement
and extend previous results on internal rearrangements of quasiparticles for
weakly coupled quantum dots in magnetic field.
