Naked mole-rat
It’s a mammal Jim, but not as we know it... Mammals are typically characterised as furry and warmblooded. The naked mole-rat is neither of these. Being underground and surrounded by hundreds of brothers and sisters, there is little fluctuation in surrounding temperature and they have all but lost the ability to regulate their body temperature physiologically. Living in the dark, they can no lon...
متن کاملDNA "fingerprinting" reveals high levels of inbreeding in colonies of the eusocial naked mole-rat.
Using the technique of DNA fingerprinting, we investigated the genetic structure within and among four wild-caught colonies (n = 50 individuals) of a eusocial mammal, the naked mole-rat (Heterocephalus glaber; Rodentia: Bathyergidae). We found that DNA fingerprints of colony-mates were strikingly similar and that between colonies they were much more alike than fingerprints of non-kin in other f...
متن کاملGenome Stability Maintenance in Naked Mole-Rat
The naked mole-rat (Heterocephalus glaber) is one of the most promising models used to study genome maintenance systems, including the effective repair of damage to DNA. The naked mole-rat is the longest lived rodent species, which is extraordinarily resistant to cancer and has a number of other unique phenotypic traits. For at least 80% of its lifespan, this animal shows no signs of aging or a...
متن کاملExploring Equivalence Metrics to Analyze Behavior in a Naked Mole Rat Colony
Many statistical and data mining techniques have been used to analyze the deluge of data generated by computerized, sensing devices. Behavioral psychologists traditionally have relied on "low-tech" methodologies for observing animal behavior in the wild and the laboratory. These methods are time intensive and laborious. When the observed animal is a colony animal, with many individuals to obser...
متن کاملUsing Frequent Pattern Mining To Identify Behaviors In A Naked Mole Rat Colony
Animal behavior analysis has, in the past, taken a very low tech approach, with direct observer surveillance and automated video surveillance as the norm. These methods are insufficient when one wants to study interactions between large numbers of animals in their housing environment. In this paper we use a housing environment that has been equipped with a system of RFID sensors. RFID transpond...
