, 1999 We examined patterns of variation in skeletal morphometrics (29 characters), allozymes (34 loci), mitochondrial DNA (mtDNA) restriction sites (n = 74) and fragments (n = 395), and mtDNA sequences (1,739 bp from cytochrome b, ND2, ND6, and the control ...

Quantum Zeno Effect Underpinning the Radical-Ion-Pair Mechanism of Avian Magnetoreception [PDF]
arXiv, 2008 The intricate biochemical processes underlying avian magnetoreception, the sensory ability of migratory birds to navigate using earths magnetic field, have been narrowed down to spin-dependent recombination of radical-ion pairs to be found in avian species retinal proteins.

Adaptive morphing of wing and tail for stable, resilient, and energy-efficient flight of avian-informed drones [PDF]
npj Robotics, 2(1), 8 (2024)Avian-informed drones feature morphing wing and tail surfaces, enhancing agility and adaptability in flight. Despite their large potential, realising their full capabilities remains challenging due to the lack of generalized control strategies accommodating their large degrees of freedom and cross-coupling effects between their control surfaces.

Population Genetic Structure and Species Delimitation of a Widespread, Neotropical Dwarf Gecko [PDF]
, 2019 Amazonia harbors the greatest biological diversity on Earth. One trend that spans Amazonian taxa is that most taxonomic groups either exhibit broad geographic ranges or small restricted ranges.

Evidence supporting the recent origin and species status of the Timberline Sparrow
, 1999 The Timberline Sparrow (Spizella taverneri), although originally described as a species, is currently classified as a subspecies of the more widespread Brewer\u27s Sparrow (S. breweri). We investigated the taxonomic status and recent evolutionary history

Evolutionary factors affecting the cross-species utility of newly developed microsatellite markers in seabirds [PDF]
, 2015 Microsatellite loci are ideal for testing hypotheses relating to genetic segregation at fine spatio-temporal scales. They are also conserved among closely related species, making them potentially useful for clarifying interspecific relationships between ...

Correlates of genetic monogamy in socially monogamous mammals: insights from Azara's owl monkeys [PDF]
, 2014 Understanding the evolution of mating systems, a central topic in evolutionary biology for more than 50 years, requires examining the genetic consequences of mating and the relationships between social systems and mating systems.

Divergence with gene flow and fine-scale phylogeographical structure in the wedge-billed woodcreeper, Glyphorynchus spirurus, a Neotropical rainforest bird. [PDF]
, 2009 Determining the relative roles of vicariance and selection in restricting gene flow between populations is of central importance to the evolutionary process of population divergence and speciation. Here we use molecular and morphological data to contrast

Global patterns of sex-biased migrations in humans [PDF]
arXiv, 2013 A series of studies have revealed the among-population components of genetic variation are higher for the paternal Y chromosome than for the maternal mitochondrial DNA (mtDNA), which indicates sex-biased migrations in human populations. However, this phenomenon might be also an ascertainment bias due to nonrandom sampling of SNPs.
