Wedge-tailed Shearwater Habitat and Trophic Niche Data 2016-2018

Stable isotope data from wedge-tailed shearwater chick feathers collected between 2015 and 2019 from two disjunct populations in eastern Australia. The dataset, hosted by the Australian Ocean Data Network, investigates spatial segregation, habitat use, and trophic niche variation between temperate and subtropical colonies. Analysis of δ15N and δ13C values reveals interannual variability in foraging strategies and niche areas.

Use Cases

• Modeling trophic niche partitioning between seabird populations based on stable isotope ratios (δ15N and δ13C).
• Analyzing interannual variability in foraging strategies in response to oceanic conditions as described in the study.
• Investigating spatial segregation and habitat use patterns of wedge-tailed shearwaters in temperate versus subtropical waters.
• Studying behavioral adaptability and potential range shifts of seabirds under projected climate-driven changes.

Strengths

• Data covers a multi-year study period from 2015 to 2019, allowing for analysis of interannual trends.
• Includes stable isotope analysis (δ15N and δ13C) from chick feathers, a common method for studying trophic ecology.
• Focuses on two distinct populations (temperate and subtropical) enabling comparative analysis.

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
