The relationship between hypoxia exposure and circulating cortisol levels in social and solitary African mole-rats: An initial report [PDF]
, 2023 Hypoxemia from exposure to intermittent and/or acute environmental hypoxia (lower oxygen concentration) is a severe stressor for many animal species. The response to hypoxia of the hypothalamic-pituitary-adrenal axis (HPA-axis), which culminates in the ...

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.

The case for extended lifespan in cooperatively breeding mammals: a re-appraisal [PDF]
PeerJ, 2020 Recent comparative studies have suggested that cooperative breeding is associated with increases in maximum lifespan among mammals, replicating a pattern also seen in birds and insects.

Functional implications of craniomandibular morphology in African mole-rats (Rodentia: Bathyergidae) [PDF]
, 2015 African mole-rats are subterranean rodents from the family Bathyergidae. The family consists of six genera, five of which (Cryptomys, Fukomys, Georychus, Heliophobius and Heterocephalus) are chisel-tooth diggers, meaning they dig underground using ...

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron
Angewandte Chemie, EarlyView.Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Phylogeny and biogeography of the African Bathyergidae: a review of patterns and processes [PDF]
PeerJ, 2019 Background We review genealogical relationships, biogeographic patterns and broad historical drivers of speciation within the Bathyergidae, a group of endemic African rodents, as well as identify key taxa which need further research.

Functional anatomy and disparity of the postcranial skeleton of African mole-rats (Bathyergidae)
Frontiers in Ecology and Evolution, 2022 The burrowing adaptations of the appendicular system of African mole-rats (Bathyergidae) have been comparatively less investigated than their cranial adaptations.

Functional histology of the skin in the subterranean African giant mole-rat: thermal windows are determined solely by pelage characteristics [PDF]
PeerJ, 2020 Excavation of burrows is an extremely physically demanding activity producing a large amount of metabolic heat. Dissipation of its surplus is crucial to avoid the risk of overheating, but in subterranean mammals it is complicated due to the absence of ...

The impact of gape on the performance of the skull in chisel-tooth digging and scratch digging mole-rats (Rodentia: Bathyergidae) [PDF]
Royal Society Open Science, 2016 The African mole-rats (Bathyergidae) are a family of rodents highly adapted for life underground. Previous research has shown that chisel-tooth digging mole-rats (which use their incisors to dig burrows) are clearly distinguishable from scratch diggers ...
