We report on magnetoconductance measurements through a weakly coupled quantumdot, containing roughly 900 electrons, in a wide magnetic field range from 0 Tto 12 T. We find modulations of the conductance resonances in the quantum Hallregime for higher integer filling factors $6> \nu_\mathrm{dot} > 2$, inaddition to modulations at $2> \nu_\mathrm{dot} > 1$ and at fractional fillingfactors $\nu_\mathrm{dot} \gtrsim 2/3$, $1/3$. Depending on the internalfilling factor, edge reconstruction inside the quantum dot leads to theformation of multiple concentric compressible regions, which contain discretecharge and are separated by incompressible rings. Quasiparticle tunnelingbetween different compressible regions results inmagnetic-field-(pseudo)-periodic modulations of the Coulomb resonances withdifferent periodicities, additional super-periodicity or non-periodic features.The evolution of the period in magnetic field indicates cyclic depopulation ofthe inner compressible regions close to integer filing factors. We study thetemperature dependence of the conductance resonances for different magneticfields. While at low fields, the resonance amplitude decays inversely withtemperature, corresponding to single-level transport, the temperaturedependence of the amplitude evolves continuously into a linearly increasingbehavior for dot filling factor $2> \nu_\mathrm{dot} > 1$. This coincides witha reduction of the charging energy by approximately a factor of 2 in the sameregime. At zero magnetic field, the temperature dependence differs forindividual resonances, and is found to depend on the closeness to quantum dotstates that couple strongly to the leads. The presented experiments complementand extend previous results on internal rearrangements of quasiparticles forweakly coupled quantum dots in magnetic field.
