ORNITHO-ENDOCRINO project data investigates endocrine mechanisms in the breeding phenology of black-legged kittiwakes in Kongsfjorden, Svalbard. The dataset includes hatch dates and breeding success from 1970-2009, with additional metrics like stress hormone levels, body mass, diet, and foraging/wintering areas collected from 1997-2009. It was produced by SCIOPS in collaboration with the Norsk Polar Institute and the Norwegian University of Science and Technology.
Use Cases
- Analyze the relationship between stress hormone levels (corticosterone) and annual variations in laying date and reproductive success.
- Model survival rates using capture-ringing-recapture data collected between 1997 and 2009.
- Correlate foraging area data from miniaturized GPS (2008-2009) with body mass and diet composition metrics.
- Investigate long-term trends in hatch dates and breeding success from 1970 to 2009 in relation to environmental factors.
- Map wintering areas from geolocator (GLS) data (2008-2009) to study migration patterns and habitat use.
Strengths
- Long-term temporal coverage for core breeding phenology metrics spanning 40 years (1970-2009).
- Multifaceted data collection includes physiological (hormone levels), behavioral (foraging), and demographic (survival) features.
- Collaborative provenance involving established polar and research institutions (Norsk Polar Institute, NTNU).
Limitations
- Sample size and row count are unknown, limiting assessment of statistical power.
- Key data streams like hormone levels and GPS tracking have shorter temporal coverage (e.g., 2000-2009, 2008-2009).
- Geographic scope is limited to a single fjord system in Svalbard, reducing generalizability.
