title: Raw data for publication: Residents and transients – fish community dynamics in a highly anthropized tidal North Sea estuary across the annual cycle

description: Occurrence, individual total length (mm), and mass (g) data of fish specimens collected from a stationary stow net (mesh size in the cod end: 12 mm) placed in the tidal Ems River near Leer, Germany (53°14’49.7”N 7°23’47.5”E). Samples were collected once per week (usually during effluent water, shortly before low tide) from November 2020 to December 2021, except for two subsequent weeks in February 2021 (total: 57 hauls). Specimens were identified to species or genus level based on morphology or using DNA barcoding (50 specimens). Total length (TL) and mass of every specimen were measured on thawed samples, excluding damaged specimens, as well as endangered and protected species (e.g., <i>Lampetra fluviatilis</i>). Available metadata are haul duration [h] and effective (i.e. submerged) net aperture [m2] averaged per haul (see journal publication for details of computation).

description: Large language models (LLMs) are increasingly used in clinical decision-making and patient education, including in complex specialties such as head and neck cancer (HNC). To evaluate the performance of ChatGPT-4o and DeepSeek-V3 in answering HNC-related clinical questions. A set of 154 questions across six clinical categories was submitted twice to both models. Responses were independently graded by head and neck surgeons using a four-point accuracy scale. Accuracy, reproducibility, and inter-model agreement were assessed. ChatGPT-4o and DeepSeek-V3 provided ‘’comprehensive/correct’’ answers in 92.2% and 89.6% of cases, respectively (<i>p</i> = .42). The accuracy ratings of both models’ responses overlapped in 85.1% of cases; however, the statistical agreement between them remained low (Cohen’s <i>κ</i> = 0.12; ICC = 0.21, <i>p</i> = .006). DeepSeek-V3 outperformed ChatGPT in <i>Treatment</i> category (96.3% vs. 81.5%, <i>p</i> = .08), while ChatGPT excelled in <i>Recovery, Complications, and Follow-up</i> (95.0% vs. 82.5%, <i>p</i> = .08); however, these differences did not reach statistical significance. Reproducibility was high for both models (ChatGPT-4o: 96.1%; DeepSeek-V3: 96.8%). Both models demonstrated strong accuracy and consistency in HNC-related queries. LLMs hold promise as reliable tools in clinical decision-making and patient education within HNCs when used with careful consideration of their inherent limitations.
