Spotted Stream Frog Genetic Sequences from Southeast Asia

Genetic sequence data from spotted stream frogs (Hylarana) collected across Southeast Asia, Sundaland, and the Philippines. The dataset includes sequences from two mitochondrial and two nuclear gene regions, used to analyze biogeographic patterns and test the 'dual-invasion' hypothesis. It contains samples from land-bridge and oceanic island populations.

Use Cases

• Reconstruct phylogenetic relationships among Hylarana species using mitochondrial and nuclear gene sequences.
• Test biogeographic hypotheses like the 'dual-invasion' scenario for Philippine endemics using sequence data.
• Analyze genetic variation and population structure across land-bridge versus oceanic island frog clades.
• Identify potential unrecognized species lineages within the Hylarana picturata, similis, and signata groups.

Strengths

• Data includes sequences from multiple genetic loci (two mitochondrial and two nuclear), enabling robust phylogenetic analysis.
• Geographic sampling covers a key biogeographic region, including mainland Southeast Asia, Sundaland, and the Philippine archipelago.
• Dataset is associated with a peer-reviewed study that tested a specific, falsifiable biogeographic hypothesis.

Limitations

• The dataset size, including the number of samples or sequences, is not specified in the provided metadata.
• Data is focused on a specific taxonomic group (Ranidae frogs), limiting broader ecological or cross-taxa applications.
• Temporal coverage of the sample collection is not detailed, which may affect interpretations of demographic history.
