Temporal degradation of data limits biodiversity research
Ecology and Evolution, 2017 AbstractSpatial and/or temporal biases in biodiversity data can directly influence the utility, comparability, and reliability of ecological and evolutionary studies. While the effects of biased spatial coverage of biodiversity data are relatively well known, temporal variation in data quality (i.e., the congruence between recorded and actual ...

Bayesian state-space models with multiple CPUE data: the case of a mullet fishery
Scientia Marina, 2017 We propose a novel Bayesian hierarchical structure of state-space surplus production models that accommodate multiple catch per unit effort (CPUE) data of various fisheries exploiting the same stock.
