Understanding the origin maintenance and loss of biodiversity in ecological systems is a goal of the highest scientific priority given the rapidity of global biodiversity loss. The dynamical behavior of an ecological communities will be considered and benchmarked against the exact predictions of an effective non-interacting model near or at stationarity. The approach provides a description of the relative species abundance leads to a quantitative understanding of the species turnover distribution and extinction times and a measure of the temporal scales of evolution. The problem of stability and diversity of an interacting ecosystem will be discussed in relation with the topology of the interaction network.
