Data from: Palaeobiology of the early sauropodomorph Mussaurus patagonicus inferred from its long bone histology

Ignacio Cerda
We present here a detailed histological study of long bones from an ontogenetic series of Mussaurus patagonicus, an early sauropodomorph from the Early Jurassic of Argentina. Twenty long bones, including humeri, femora and fibulae, obtained from thirteen individuals of different body sizes were sampled for histological analysis. In general terms, the cortical bone is formed by a well vascularized fibrolamellar and parallel fibred bone. Except for the smaller individuals, cyclical growth marks (CGMs) are well...

Taxonomy based on limited genomic markers may underestimates species diversity of rockhopper penguins and threaten their conservation

Delimiting recently diverged species is challenging. During speciation, genetic differentiation may be distributed unevenly across the genome, as different genomic regions can be subject to different selective pressures and evolutionary histories. Reliance on limited numbers of genetic markers that may be underpowered can make species delimitation even more challenging, potentially resulting in taxonomic inconsistencies. Rockhopper penguins of the genus Eudyptes comprise three broadly recognized taxa: northern (E. moseleyi), southern (E. chrysocome), and eastern rockhopper (E....

Information from diversity inventories is used to study patterns of biodiversity and species distribution; likewise, it may be useful to identify priority areas for conservation, and to guide future sampling efforts. In this context, we compiled information on non-volant small mammal communities from the high Andes (> 2,000 m.). Here we present an open resource data set containing information diversity (species composition, number of individuals captured ), inventory design (type of traps, sampling efforts), and...
