Differential high‐altitude adaptation and restricted gene flow across a mid‐elevation hybrid zone in Andean tit‐tyrant flycatchers
A previously unknown hybrid zone between recently diverged flycatchers (Aves, Tyrannidae) with partially overlapping elevational ranges is reported, concluding that differential respiratory specialization on atmospheric pressure combined with competitive exclusion maintains replacement along an elevational contour, despite interbreeding.

Test for adaptive convergence in hemoglobin (Hb) function among high-altitude passerine birds that are native to the Qinghai-Tibet Plateau and examines whether convergent increases in Hb–O2 affinity have a similar molecular basis in different species.

It is found that prevailing emission inventories underestimate black carbon levels in the United States through the first decades of the 20th century, suggesting that black carbon’s contribution to past climate forcing may also be underestimated.
Global inequity in scientific names and who they honor
This work interrogates how power and authority over the natural world are claimed through Western scientific naming practices to evaluate the legacies of imperialism, dispossession, and exclusion in these practices and contextualizes disparities in naming and authorship within broader global structures of access and power.
Satellite imagery reveals new critical habitat for Endangered bird species in the high Andes of Peru
The utility of Google Earth for applied conservation is demonstrated and improved prospects for the persistence of the Polylepis-associated avifauna are suggested.
Elevational patterns of bird species richness on the eastern slope of Mt. Gongga, Sichuan Province, China
It is found that MDE, IB and STR play important but varying roles in shaping the elevational richness patterns of different bird species categories, and model-averaging indicates that small-ranged species appear to be mostly influenced by IB, as opposed to large-ranged Species, which exhibit patterns more consistent with the MDE model.
Mobile hotspots and refugia of avian diversity in the mountains of south‐west China under past and contemporary global climate change
To identify hotspots of endemic and non‐endemic avian diversity in the mountains of south‐west China and delineate biodiversity corridors that connect the faunas of northern and southern Asia. To…
Dung‐associated arthropods influence foraging ecology and habitat selection in Black‐necked Cranes (Grus nigricollis) on the Qinghai–Tibet Plateau

New insights are provided into the role of livestock dung in defining foraging habitats and resources for insectivorous predators and how dung‐associated arthropods affect trade‐offs between vegetation structure, arthropod abundance, and access to prey.
Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows
A case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution is revealed, shedding light on early stages of adaptive evolution to a novel environment.
Life history predicts flight muscle phenotype and function in birds.

This approach provides a framework of the selective forces that shape functional variation within and between species, and found more variation in flight muscle traits within species than has been previously described between species of birds under 20 g.
