Natural disturbance regimes play key roles in shaping forest structure and development at stand and landscape levels. Disturbances are complex and variable, such that classical dichotomous characterization of disturbance regimes as following large infrequent disturbances or patch dynamics is too simplistic, especially when the resulting damage is more severe than the baseline of a single tree patch dynamic, but not severe enough to represent large infrequent disturbance. Ongoing climate change affects mountain Pic...

The paper is focused on manifestations of chaotic behavior in the time series of pollution concentration. Deterministic chaos denotes a type of complex behavior of a deterministic dynamical system. The most important algorithms for data representation, prediction, phase space reconstruction, dimension, entropies, persistence and Lyapunov estimation are applicate here. At first we estimated the time delay and the embedding dimension, which is needed for the Lyapunov exponent estimation and for the phase space recon...
