In this study, we employ in situ, meteorological, and remote sensing data to estimate chlorophyll-a concentration at different depths in a South American freshwater ecosystem, focusing specifically on a lake in southern Chile known as Lake Maihue. For our analysis, we explored four different scenarios using three deep learning and traditional statistical models. These scenarios involved using field data (Scenario 1), meteorological variables (Scenario 2), and satellite data (Scenarios 3.1 and 3.2) to predict chlorophyll-a levels in Lake Maihue at three different depths (0, 15, and 30 m). Our choice of models included SARIMAX, DGLM, and LSTM, all of which showed promising statistical performance in predicting chlorophyll-a concentrations in this lake. Validation metrics for these models indicated their effectiveness in predicting chlorophyll levels, which serve as valuable indicators of the presence of algae in the water body. The coefficient of determination values ranged from 0.30 to 0.98, with the DGLM model showing the most favorable statistics in all scenarios tested. It is worth noting that the LSTM model yielded comparatively lower metrics, mainly due to the limitations of the available training data. The models employed, which use traditional statistical and machine learning models and meteorological and remote sensing data, have great potential for application in lakes in Chile and the rest of the world with similar characteristics. In addition, these results constitute a fundamental resource for decision-makers involved in the protection and conservation of water resource quality.

Goiás state, situated in the Cerrado biome harbors several water bodies belonging to the Paraná, São Francisco, and Tocantins-Araguaia hydrographic regions. However, there are several gaps in the knowledge about the diversity and geographic distribution of aquatic invertebrates in the state, including microcrustaceans of the Superorder Cladocera. Thus, this study aims to elaborate an updated list of cladoceran species occurring in Goiás, using data from 37 literature sources and original samples from different ecosystems and localities. The history and type of publications were evaluated. The number of studies between 1988 and 2022 and the type of publications and species richness were listed. The literature data indicated that most studies reporting or describing species for Goiás were found in papers published in indexed journals (75%). Tocantins-Araguaia was the hydrographic region with the highest number of studies (20). The number of observed species was strongly related to the number of studies (r2 = 0.59; p < 0.0001). When observing literature data and findings from sampling, 92 species were recorded with five news reports: Scapholeberis freyi, Grimaldina freyi, Parvalona parva, Chydorus brevilabris, and Picripleuroxus quasidenticulatus. The number and composition of species in Goiás state should be considered relevant. However, the observed richness is lower than expected (114 spp), suggesting the need for increased sampling effort. The focus of this sampling should preferably occur in areas lacking information.
