Fossil and modern penguin tarsometatarsi: cavities, vascularity, and resilience

Integrative Zoology, EarlyView.
In tarsometatarsi of Eocene and extant penguins, the distribution of primary diaphyseal nutrient foramina as well as dimensions of medullary cavities appears to align more with overall body‐size categories than geological age, albeit the extinct genus Anthropornis is unique in both respects.

Mitogenomes of museum specimens provide new insight into species classification and recently reduced diversity of highly endangered Nomascus gibbons

Integrative Zoology, EarlyView.
Our findings reveal that the western black crested gibbon (Nomascus concolor) did not divide into different subspecies, and the relatively low level of genetic diversity emphasizes the importance of monitoring this indicator for vulnerable wildlife.

Bayesian StairwayPlot for Inferring Single Population Demographic Histories From Site Frequency Spectra

Molecular Ecology Resources, EarlyView.
ABSTRACT The StairwayPlot approach provides an elegant, flexible and powerful method to estimate complex demographic histories of single populations from site frequency spectrum data. It uses expected coalescent times to compute the expected site frequency spectrum within a multinomial likelihood function.

Assessing fish movement and physiological traits along a salinity gradient by measuring stable oxygen isotope values in fish blood water and muscle water

Methods in Ecology and Evolution, EarlyView.
Abstract Variations in stable oxygen isotopes (δ18O) in the body water of animals reflect changes in δ18O values in environmental water and the animals' physiological processes. Euryhaline/anadromous/catadromous fish species move across salinity gradients; changes in δ18O values in environmental water thus lead to changes in δ18O values in body water ...
