The diet of Prionotus nudigula in coastal waters off Uruguay and northern Argentina (36°–41° S) and their variation in relation to body size, region and season were determined by analysis of stomach contents. Additionally, the trophic level of this species was estimated to establish its ecological role in this marine region. A total of 352 individuals were analysed, of which 308 (87.05%), ranging from 78 to 285 mm in total len...

This paper proposes a new statistical framework for modeling precipitation patterns in a specific geographic region using Hidden Markov Models (HMMs). Unlike conventional HMMs, where the hidden state process is Markovian, our approach introduces non-Markovian behavior by incorporating phase-type distributions to model state durations. This extension allows for a more realistic representation of alternating dry and wet periods,...
