Ecological and evolutionary preconditions of extended longevity in subterranean rodents
In the social African mole rat species with reproductive division of labor, the mortality of workers in wildlife is considerably higher than in breeders, while significant interspecific differences in the lifespan patterns may emerge in captivity, according to the evolutionary theory of aging.

Bone remodeling in the longest living rodent, the naked mole‐rat: Interelement variation and the effects of reproduction
It is concluded that other factors associated with development (and not uniquely related to biomechanical loading) can also have an important role in the development of bone remodeling. Expand
Life expectancy, family constellation and stress in giant mole-rats (Fukomys mechowii)
The influence of the social environment of giant mole-rats on intrafamilial aggression levels, indicators of long-term stress, and mortality, and, ultimately, mortality is analysed. Expand
Plasma oxidative stress in reproduction of two eusocial African mole-rat species, the naked mole-rat and the Damaraland mole-rat

One of the most prominent life-history trade-offs involves the cost of reproduction. Oxidative stress has been proposed to be involved in this trade-off and has been associated with reduced lifeExpand
Long bone histomorphogenesis of the naked mole‐rat: Histodiversity and intraspecific variation
A high histodiversity of bone matrices and the formation of secondary osteons in NMRs is described, which indicates that postnatal osteogenesis and its consequent cortical stratification most likely represents a plesiomorphic thermometabolic strategy among endotherms which has been suggested to be regulated by endogenous rhythms.

Reproductive Characteristics of the Northern Mole Vole at the Northeastern Periphery of Species Range
Analysis of age at maturity, timing of pregnancy, and rates of postnatal development in reproductive pairs of northern mole voles kept under laboratory conditions has shown that the test parameters in a population living at the northeastern periphery of the species range (Novosibirsk oblast) are different from those in apopulation from the optimal zone of the range.

The case for extended lifespan in cooperatively breeding mammals: a re-appraisal
Data supports a causal role of subterranean living on lifespan extension in mammals and does not find any consistent, strong evidence that cooperative breeders have longer lifespans than other mammals after having controlled for variation in body mass, mode of life and data quality. Expand
Age-related differences in physiology and survival of northern red-backed voles (Myodes rutilus) in captivity
The welfare and lifespan of wild animals in captivity may be affected by the environmental conditions in the period preceding removal of the animal from the wild, as the individual longevity of red-backed voles varied between years of captivity. Expand
Do cooperatively breeding mammals live longer? A re-appraisal
Current data makes it impossible to rule out a causal role of subterranean living on lifespan extension in mammals, and that any future studies wanting to test for such an association should wait until more high quality longevity data is available from a wider range of permanently subterranean species. Expand
Cortical bone adaptation and mineral mobilization in the subterranean mammal Bathyergus suillus (Rodentia: Bathyergidae): effects of age and sex
The data indicate no age-related decline in mineral content in B. suillus, and provides strong support for a pattern of sexual dimorphism in skeletal homeostasis, similar to that occurring in humans and other mammals, with females losing more bone throughout aging as compared to males due to reproductive factors.

African Mole-Rats: Ecology and Eusociality
This work has shown that the genetic structure of Mole-Rat populations and the evolution of sociality on African Mole-Rats populations is similar to that of other mammal species studied in the same area. Expand
A new glanapterygine catfish of the genus Listrura (Siluriformes: Trichomycteridae) from the southeastern Brazilian coastal plains
Listrura picinguabae, new species, is described from small tributary streams of rio da Fazenda, an isolated coastal river in Picinguaba, Sao Paulo State, southeastern Brazil. It is distinguished fromExpand
Seneszenz bei afrikanischen Sandgräbern (Bathyergidae, Rodentia) unter besonderer Berücksichtigung der Gattung Fukomys
Seneszenz ist aus evolutionsbiologischer Sicht ein hoch interessantes Phanomen. Viele Theorien sind entwickelt worden, um die ultimaten und proximaten Faktoren zu identifizieren, die dem Altern zuExpand
Sexual activity and reproduction delay ageing in a mammal
Here, it is shown that in a eusocial mammal, a nearly identical life history has evolved. Expand
Antioxidants do not explain the disparate longevity between mice and the longest-living rodent, the naked mole-rat
Maintenance of constant antioxidant defenses with age in NMRs concurs with previous physiological data, suggesting delayed aging in this species, and is nonetheless unlikely that antioxidant defenses are responsible for the eight-fold longevity difference between these two species. Expand
Biodemographic analysis of male honey bee mortality
It is shown that males initiating flight at a young age experience more flight events during their lifetime, and no (negative) relation between the age at flight initiation and lifespan exists, as might be predicted on the basis of the antagonistic pleiotropy theory of aging. Expand

Non-reproductive females in families of eusocial common mole-rats (Cryptomys sp., Rodentia) are not suppressed by their mother, (either behaviourally or pheromonally) as is generally assumed. They doExpand
