Dental peculiarities in the silvery mole-rat: an original model for studying the evolutionary and biological origins of continuous dental generation in mammals [PDF]
PeerJ, 2015 Unravelling the evolutionary and developmental mechanisms that have impacted the mammalian dentition, since more than 200 Ma, is an intricate issue. Interestingly, a few mammal species, including the silvery mole-rat Heliophobius argenteocinereus, are ...

Journal of Morphology, Volume 284, Issue 3, March 2023., 2023 This work highlights morphological variations in skulls and humerus in extant rodents with varying locomotion, to predict this parameter in the extinct species Diamantomys luederitzi (Early Miocene, Napak, Uganda). The use of LDA and phylogenetic flexible discriminant analyses with different data sets (measurements and landmarks) allow a better ...

Journal of Morphology, Volume 284, Issue 1, January 2023., 2023 Our morphometric analyses permit to discuss the putative behavioral and environmental parameters shaping the skull of ground squirrels in relation to their digging activity. Our paper reports that these sciurid rodents do show convergent morphological traits on both cranium and mandible in relation to fossorial life.

Postnatal ontogeny of the femur in fossorial and semiaquatic water voles in the 3D‐shape space
The Anatomical Record, Volume 305, Issue 5, Page 1073-1086, May 2022., 2022 Abstract Water voles of the genus Arvicola constitute an excellent subject to investigate to which extent function affects postnatal developmental growth of limb structures in phylogenetically close species. We performed a comparative analysis of postweaning femur form changes between Arvicola sapidus (semiaquatic) and Arvicola scherman (fossorial ...

Social structure predicts genital morphology in African mole-rats. [PDF]
PLoS ONE, 2009 BACKGROUND:African mole-rats (Bathyergidae, Rodentia) exhibit a wide range of social structures, from solitary to eusocial. We previously found a lack of sex differences in the external genitalia and morphology of the perineal muscles associated with the

Frontiers in Ecology and Evolution, 2021 African mole-rats of the genus Fukomys (Northern common mole-rats) combine a monogamous mating system and pronounced sexual size dimorphism; a pattern highly untypical for mammals.

Biological Reviews, Volume 97, Issue 1, Page 115-140, February 2022., 2022 ABSTRACT The naked mole‐rat (Heterocephalus glaber) has fascinated zoologists for at least half a century. It has also generated considerable biomedical interest not only because of its extraordinary longevity, but also because of unusual protective features (e.g.

Biogeography of Angolan rodents: The first glimpse based on phylogenetic evidence
Diversity and Distributions, Volume 27, Issue 12, Page 2571-2583, December 2021., 2021 Abstract Aim Assessment of phylogenetic diversity and biogeographical affinities of the rodent fauna from one of the most neglected areas in Africa. Location Angola (with biogeographical implications in adjacent areas). Methods Inference of mitochondrial phylogenies for rodent genera occurring in Angola, delimitation of molecular operational taxonomic ...

Extended longevity of reproductives appears to be common in Fukomys mole-rats (Rodentia, Bathyergidae). [PDF]
PLoS ONE, 2011 African mole-rats (Bathyergidae, Rodentia) contain several social, cooperatively breeding species with low extrinsic mortality and unusually high longevity.

Animals, 2023 Small size in mammals usually restricts long-term, frequent monitoring of endocrine function using plasma as a matrix. Thus, the non-invasive monitoring of hormone metabolite concentrations in excreta may provide an invaluable approach.
