The recently proposed concept of´ endangered living fossils'(ELFs) integrates high-
endangered status and evolutionary singularity for any species. In this review, I gathered …

The extinction of California's flightless duck, Chendytes lawi, stands out in the faunal history
of North America because it involved a marine animal that disappeared in the late Holocene …

Diving animals must sustain high activity with limited O2 stores to successfully capture prey.
Studies suggest that increasing body O2 stores supports breath-hold diving, but less is …

Authentic DNA sequences are crucial for reliable evolutionary inference. Concerns about
the identification of DNA sequences have been voiced several times in the past but few …

El Niño has profound influences on ecosystem dynamics. However, we know little about
how it shapes vertebrate faunal community composition over centennial time scales, and …

A major challenge in biology is to link cellular and molecular variations with behavioral
phenotypes. Here, we studied somatosensory neurons from a panel of bird species from the …

Insight into complex evolutionary histories continues to build through broad comparative
phylogenomic and population genomic studies. In particular, there is a need to understand …

We describe leg bones of a larger-sized representative of the Anatidae from the Tortonian of
the Hammerschmiede clay pit in southwestern Germany. Allgoviachen tortonica, n. gen. et …

Here we report the first recovery, sequencing, and identification of fossil biomineral proteins
from a Pleistocene fossil invertebrate, the stony coral Orbicella annularis. This fossil retains …

Changes in this supplement include the following:(1) 4 species (Grus monacha,
Macronectes halli, Elaenia parvirostris, and Turdus naumanni) are added to the main list on …
