Species-specific dynamics may cause deviations from general biogeographical predictions - evidence from a population genomics study of a New Guinean endemic passerine bird family (Melampittidae).

This study uses population genomics to compare two Melampittidae bird species in New Guinea, finding that habitat dependence affects population connectivity in the rare species.

DNA metabarcoding reveals the threat of rapidly expanding barred owl populations to native wildlife in western North America

This study uses DNA metabarcoding to analyze the diet of invasive barred owls in western North America, revealing their broad predatory impact on native species.

Sodium channel toxin-resistance mutations do not govern batrachotoxin (BTX) autoresistance in poison birds and frogs

The paper shows that Nav mutations are not responsible for BTX resistance in poison frogs and birds, suggesting alternative mechanisms like toxin sequestration.

Speciation and gene flow across an elevational gradient in New Guinea kingfishers

The paper tests the gradient speciation hypothesis in New Guinea kingfishers, finding reciprocally monophyletic gene trees and evidence of gene flow maintaining species boundaries.

Genomic variation and population histories of spotted (Strix occidentalis) and barred (S. varia) owls

This study analyzes genomic variation and population histories of spotted and barred owls, identifying hybrids and revealing genetic isolation and population bottlenecks.
