AI model analyzes 52 factors to flag extinction risks for 10,000 fish species Whether it's redfin pickerel in the Kennebec River or sturgeon in the Great Lakes, nearly one-third of freshwater fish species are facing possible extinction, threatening food supplies, ecosystems and outdoor recreation.

Environment , taxonomy, and socioeconomics predict non-imperilment in freshwater fishes The dataset developed for this study involved the compilation and processing of 12 global data sources (Table 1). Predictive data sources were selected based on their offering of information relevant to one or more of three broad categories: Environmental, Socioeconomic, and Intrinsic. Each of the initial 122 candidate predictive variables in our dataset was also classified into one of 13 sub-categories (i.e., Habitat, Climate, Hydrology, Economy, Development, Footprint, Threats, Impoundments, Taxonomy, Physiology, Life-history, Knowledge, Conservation), based on their domain. A predictor representing knowledge gaps was calculated using unknown attributes, the number of predictive variables with NA values, for each species. For the present study, we only used one response variable (i.e., the latest IUCN Red List conservation status), provided as binary (imperiled and non-imperiled) and ordinal (five classes) responses for random forest and ordinal forest models, respectively. For a more detailed description of each variable in the conflated dataset, see Table S1. Intrinsic and species response data We accessed species conservation data from the IUCN Red List of Threatened Species26 (2024-v2) using the IUCN Red List API: http://apiv3.iucnredlist.org. Data included the latest conservation assessments, identified threats, and necessary management actions for species recovery. Original threat classes (15) were binned into...

Global distribution of the number of imperiled freshwater fishes

Consequently, freshwater taxa are among the most threatened, yet many species have not been assessed for conservation status. We developed a machine learning framework that predicts the conservation status of freshwater fishes.

Figure 3. Redundancy analysis of the seven behavioural variables (black arrows) with metabolic traits (blue arrows) as constraints in toothcarp (see Suppl. material 3: fig. S6 for the plot for mosquitofish). Each red dot represents an individual.

Metabolism–behaviour link: in toothcarp, movement was more related to baseline metabolism (SMR), with individuals with higher SMR moving less. In mosquitofish, metabolism explained little of the behavioural variation.

Figure 2. Box-plots of movement behavioural variables of mosquitofish (purple) and toothcarp from both sexes (yellow) pooled across salinity treatments. Metrics include the proportion of time near edges, median speed, proportion of time stationary, median turning speed, proportion of time sharply turning (> 45 °/s), proportion of arena visited, and the coefficient of variation (CV) of arena use.

Mosquitofish spent more time moving and used space more uniformly, whereas toothcarp showed more restricted, stop–go movement, shedding light on differences in ecological strategy and invasion success.

Figure 1. Box-plots of metabolic responses (SMR, MMR, FAS, and AAS) for female mosquitofish (purple), female toothcarp (green), and male toothcarp (yellow) across salinity treatments.

Toothcarp maintained metabolic performance across salinities, while mosquitofish showed lower aerobic performance at elevated salinity.

Data from: Global patterns and gaps in research on salinity tolerance of inland fishes Freshwater salinization is an emerging threat impacting one-third of the world's freshwater bodies. However, the salinity tolerance of many inland fishes remains understudied, despite being a crucial factor in determining species distributions and fitness. We analyzed a global database of experimental salinity tolerance of inland fishes, compiled from 128 sources, to investigate geographical and taxonomic biases. Additionally, we examined how salinity tolerance relates to fish traits and how experimental data align with field-reported salinity levels..Experimental data on salinity tolerance was available for less than 1% of the world’s inland fishes, with data severely lacking from diverse tropical regions and orders such as Siluriformes. Most studies focused on relatively large and widely distributed species from North America, Europe and Oceania. Our results showed that fish salinity tolerance was strongly associated with fish habitat type, taxonomy, aspects of morphology, migratory behaviour and the experimental approach used (direct vs. gradual). Our results also showed significant, though sometimes weak relationships between field-reported salinity levels and experimental estimates. Overall, maximum salinities reported for habitats occupied by inland fishes were lower than experimentally-estimated tolerances.Improved understanding of fish salinity tolerance will be essential for assessing impacts of freshwater salinization and forecasting the invasion potential of non-native species.

In this paper we observed that environmental fluctuations (conductivity, water level, oxygen) in coastal Mediterranean ponds barely affect zooplankton community structure and diversity, since zooplankton organisms present adaptations to these dynamic ecosystems.
