Sociality in African mole-rats
Nigel Bennett Dept of Zoology and Entomology, University of Pretoria, Pretoria 0002, South Africa. A characteristic of COOPERATIVELY BREEDING mammals (see Glossary), where individuals other than the parents help care for offspring, is that reproduction is partitioned unequally among members of the social group (REPRODUCTIVE SKEW), with socially dominant individuals monopolizing breeding opportu...
متن کاملA Distinct Role of the Queen in Coordinated Workload and Soil Distribution in Eusocial Naked Mole-Rats
We investigated how group members achieve collective decision-making, by considering individual intrinsic behavioural rules and behavioural mechanisms for maintaining social integration. Using a simulated burrow environment, we investigated the behavioural rules of coordinated workload for soil distribution in a eusocial mammal, the naked mole-rat (Heterocephalus glaber). We tested two predicti...
متن کاملPup Shoving by Adult Naked Mole-Rats
Adult naked mole-rats (Heterocephalus glaber) characteristically perform an unusual behavior toward young: they shove small pups frequently and vigorously around the nest. We studied 15 litters in five captive colonies to quantify which adults shove pups, changes in shoving frequencies as pups develop, how external disturbances affect pup-shoving frequencies, and behavior of juveniles that were...
متن کاملGrowing out of a caste--reproduction and the making of the queen mole-rat.
Naked mole-rats have a eusocial colony structure consisting of non-reproductive workers and a reproductively active caste where a single, dominant queen and 1-3 males produce all of the offspring. Well-established queens have elongated bodies that characterize their caste. Worker females retain the ability to transform into queens, however the trigger and time course for this physical transform...
متن کاملChapter 5: Neuroanatomy and neuroendocrinology of the GnRH system of Cape mole-rats and the Natal mole-rats
This study mapped the distribution and morphology of the GnRH neuronal systems of Cape and Natal mole-rats and the GnRH-immunoreactivity of the median eminence was quantified. A comparison was made between the winter and summer seasons in both species and also between dominant and subordinate animals in the Natal mole-rat species. Although the Cape mole-rat is larger than the Natal mole-rat, it...
