Data Sheet 1_Feeding and reproduction of the tropical coastal copepod Pseudodiaptomus anna

Southeast Asian tropical coastal ecosystems are the focus of this dataset. It contains experimental results on the survival, feeding, and reproduction of the copepod Pseudodiaptomus annandalei under combined temperature (26, 29, 32, 35 °C) and copper (0-40 µg L⁻¹) exposure over seven days. The dataset was authored by Ngoc-Anh Vu and last updated on 2026-05-29.

Use Cases

• Modeling the non-linear interaction between temperature and copper toxicity on zooplankton based on the described experimental gradients.
• Assessing the thermal optimum for feeding and reproduction in a dominant tropical copepod based on performance peaks at 32°C.
• Studying variability in contaminant response within wild populations based on the high individual variability noted in the description.
• Informing ecological risk assessments for coastal pollution under climate change based on the realistic stressor gradients used.

Strengths

• Data covers a realistic gradient of two key stressors (5 copper levels, 4 temperature levels) relevant to tropical coastal ecosystems.
• Measures three key biological endpoints: adult survival, cumulative faecal pellet production, and cumulative nauplii production over a 7-day period.
• Released under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The dataset is relatively small at 4.4 MB, which may indicate a limited sample size.
