Genetic Data for Hong Kong Yellow-crested Cockatoos, Including MtDNA and VCF Files

Astrid Andersson's dataset contains genetic data for a non-native population of approximately 200 critically endangered Yellow-crested Cockatoos (Cacatua sulphurea) in Hong Kong. It includes whole genome sequences, mitochondrial DNA alignments, and nuclear DNA VCF files, last updated on 2026 -04-20. The data was used to assess the genetic health and conservation value of this introduced urban population.

Use Cases

• Assessing inbreeding levels and genetic diversity in a small, isolated population based on whole genome sequences.
• Comparing genetic characteristics like effective population size (Ne) and nucleotide diversity across different wild parrot populations.
• Investigating population origins and admixture through mitochondrial DNA and nuclear DNA VCF analysis.
• Evaluating the potential of an introduced urban population as a genetic reservoir for a critically endangered species.

Strengths

• Includes whole genome sequences, mitochondrial DNA alignments, and nuclear DNA VCF files for a specific population.
• Data is focused on a population of approximately 200 critically endangered Yellow-crested Cockatoos.
• Comparisons are made to native-range C. sulphurea, Sulphur-crested Cockatoos, and five additional wild parrot populations.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
