Preservation of avian blood and tissue samples for DNA analyses
TLDR
The efficiency of chemical solutions containing high concentrations of salts and detergent at preserving DNA in bird tissue and blood samples stored at ambient temperature for extended periods of time and DNA extracted from samples preserved in these solutions for up to 24 weeks is tested.

DNA profiles of the eastern Canadian wolf and the red wolf provide evidence for a common evolutionary history independent of the gray wolf
The origin and taxonomy of the red wolf (Canis rufus) have been the subject of considerable debate and it has been suggested that this taxon was recently formed as a result of hybridization between…

Sequence variation at the major histocompatibility complex locus DQ beta in beluga whales (Delphinapterus leucas)
TLDR
Although the amount of allelic variation is low when compared with terrestrial mammals, the nature of the substitutions in the peptide binding sites indicates an important role for the DQ beta locus in the cellular immune response of beluga whales.

A RELIABLE MOLECULAR METHOD OF GENDER DETERMINATION FOR MAMMALS
TLDR
A polymerase chain reaction–based method was developed for gender determination in a wide variety of marine and terrestrial mammals, including cetaceans, pinnipeds, ungulates, canids, and ursids and only 1 primer set is needed for both gender determination and internal verification of amplification.

Genetic nature of eastern wolves: Past, present and future
TLDR
Recent molecular studies suggest that the eastern wolf is not a gray wolf subspecies, nor the result of gray wolf/coyote hybridization, and hybridization may be enhancing the adaptive potential of eastern wolves, allowing them to more effectively exploit available resources in rapidly changing environments.

Association of autism severity with a monoamine oxidase A functional polymorphism
TLDR
It is concluded that functional MAOA‐uVNTR alleles may act as a genetic modifier of the severity of autism in males.

Osteological differences between two sympatric forms of bottlenose dolphins (genus Tursiops) in Chinese waters
TLDR
Results provided strong evidence that the two sympatric forms of Tursiops in Chinese waters are isolated reproductively and do not support the current view of a monotypic genus.

Realized Reproductive Success of Polygynous Red-Winged Blackbirds Revealed by DNA Markers
TLDR
Genetically based measures of reproductive success show that individual males realize more than 20% of their overall success from extra-pair fertilizations, on average, and that this form of mating behavior confounds traditional measures of male success.

DNA fingerprinting reveals relation between tail ornaments and cuckoldry in barn swallows, Hirundo rustica
TLDR
Although elongated males were clearly preferred by females at the time of pair formation, tail elongation may have hampered the ability of a male to guard his mate, resulting in an increase in extrapair fertilizations (EPFs).

Detecting recent speciation events: the case of the finless porpoise (genus Neophocaena)
TLDR
A study conducted based on morphological characters and microsatellite and mitochondrial markers suggests that the two morphologically distinguishable forms of finless porpoise exist in sympatry in the strait of Taiwan and therefore represent different species as defined by the biological species concept.
