First Record of Dark-sided Flycatcher (<i>Muscicapa sibirica</i>) for Temperate North America: Intercontinental Vagrancy and Migratory Misorientation. [PDF]
Ecol EvolWe document the extraordinary occurrence of a Dark‐sided Flycatcher (Muscicapa sibirica)—a migratory passerine from East Asia—in California, USA. We discuss the little‐known phenomenon of intercontinental vagrancy in migratory landbirds and examine this case study in detail, providing analysis of the age, molt status, subspecies, and likely origins of ...

Genomic Signatures and Demographic History of the Widespread and Critically Endangered Yellow-Breasted Bunting. [PDF]
Mol EcolABSTRACT Population declines may have long‐term genetic consequences, including genetic erosion and inbreeding depression, which could affect species' evolutionary potential and increase their risk of extinction. Small populations are more vulnerable to genetic threats than common species, but even species with large populations can also be at risk of ...

Mitogenomic Relationships and Demographic History of the Daurian Ground Squirrel (<i>Spermophilus dauricus</i>) in Response to Human Activity. [PDF]
Ecol EvolAn analysis of population genetics on the basis of the mitochondrial genomes of widely sampled Spermophilus dauricus, integrated with the results of species distribution models, reveals the following: There are differences in population differentiation among the three Spermophilus dauricus populations in the Northeast Plain, the Hulunbuir Plateau, and ...

Sedimentology, Volume 70, Issue 1, Page 235-258, January 2023., 2023 ABSTRACT Arctic warming and permafrost thaw visibly expose changes in the landscape of the Lena River delta, the largest Arctic delta. Determining the past and modern river regime of thick deltaic deposits shaping the Lena River mouth in north‐eastern Siberia is critical for understanding the history of delta formation and carbon sequestration. Using a

Ecological niche models reveal divergent habitat use of Pallas's cat in the Eurasian cold steppes
Ecology and Evolution, Volume 12, Issue 12, December 2022., 2022 The Pallas's cat with a widespread but isolated distribution shows a divergent habitat selection across Eurasian cold steppes. A sub‐taxon climate change projection revealed the different responses of the Pallas's cat subspecies to future global warming.

Dating Tips for Divergence-Time Estimation [PDF]
, 2015 The molecular clock is the only viable means of establishing an accurate timescale for Life on Earth, but it remains reliant on a capricious fossil record for calibration. 'Tip-dating' promises a conceptual advance, integrating fossil species among their

Central European forest–steppe: An ecosystem shaped by climate, topography and disturbances
Journal of Biogeography, Volume 49, Issue 6, Page 1006-1020, June 2022., 2022 Abstract The occurrence and origin of dry grasslands and their rich biota in the moderately humid Central‐European climate have fascinated scientists for over a century. Modern palaeoecological and phylogeographical data support earlier hypotheses that these grasslands are late Pleistocene relicts and can therefore be considered part of the Eurasian ...
