We assessed by using a bomb calorimeter the energy density of the main species of Patagonian freshwater ecosystems, including fish, crustaceans, gastropods, oligochaetes, and insects. Fish (5048-5789 Cal/g) were the most energy density group, followed by insects (5062- 5232), crustaceans (3364-3994), oligochaetes (3471) and gastropods (1143). These data consist on the first direct energy density estimations of freshwater species and are intended as a baseline information for modelling the energy fluxes in Patagonian freshwater ecosystems. |

Environmental conditions experienced by aquatic organisms are archived in biogenic carbonates such as fish otoliths, bivalve shells and coral skeletons. These calcified structures present an accretionary growth and variations in optical properties - color or opacity - that are used to reconstruct time. Full and reliable exploitation of the information extracted from these structures is, however, often limited as the metabolic processes that control their growth and their optical properties are poorly understood. Here, we propose a new modeling framework that couples both the growth of a biogenic carbonate and its optical properties with the metabolism of the organism. The model relies on well-tested properties of Dynamic Energy Budget (DEB) theory. It is... |
