Medium and large-sized mammals in an Atlantic Forest fragment of Brazil: recording of threatened species

open access: yesJournal of Threatened Taxa, 2019
Deforestation and habitat fragmentation affect to a great extent larger wild mammals, which require large areas to establish their populations.  These mammals can have important functions in the structure and dynamics of tropical forests, acting as seed ...

Morphological homology, evolution, and proposed nomenclature for bear dentition [PDF]

open access: yesActa Palaeontologica Polonica, 2019
Bears are a group of carnivores with diverse diets and complicated dental structure. Several large rearrangements of dental structures are known in different lineages of bears, making the homology of dental structures between the different bears ...

Postcranial remains of basal typotherian notoungulates from the Eocene of northwestern Argentina [PDF]

open access: yesActa Palaeontologica Polonica, 2020
Notoungulates represent the most taxonomically diverse and temporally and geographically widespread group among South American native ungulates. Here, we analyze anatomical and systematic aspects of proximal tarsal bones recovered from the Lower and ...

Mammalian forelimb evolution is driven by uneven proximal-to-distal morphological diversity

open access: yeseLife, 2023
Vertebrate limb morphology often reflects the environment due to variation in locomotor requirements. However, proximal and distal limb segments may evolve differently from one another, reflecting an anatomical gradient of functional specialization that ...

Evidence for parallel development of ever-growing molars in Early Pleistocene rodents from southern Spain and their paleoenvironmental implications

open access: yesActa Palaeontologica Polonica, 2023
In this paper, we present a detailed survey on the rodent fauna from the site of Barranco de los Conejos (Guadix-Baza Basin, southern Spain). Its rodent fauna is composed of three arvicolines (Orcemys giberti, Manchenomys oswaldoreigi, and Tibericola ...

Mapping the Space of Genomic Signatures [PDF]

open access: yes, 2014
We propose a computational method to measure and visualize interrelationships among any number of DNA sequences allowing, for example, the examination of hundreds or thousands of complete mitochondrial genomes. An "image distance" is computed for each pair of graphical representations of DNA sequences, and the distances are visualized as a Molecular ...
