Inbreeding in Littledale's whistling rat Parotomys littledalei.
Despite its rarity in nature, inbreeding is sometimes evident in species occupying ephemeral, unpredictable habitats, and which occur at low densities. One such species is Littledale's whistling rat, Parotomys littledalei, a murid rodent endemic to the south-west arid region of South Africa. Using a captive population of P. littledalei, I studied mate choice for kin and nonkin, and the reproduc...
متن کاملVariability in alcohol preference in Maudsley reactive inbred male rats
Maudsley Reactive (MR) inbred rats, selected for high defecation in an open field, relative to Maudsley Nonreactive (MNR) rats, have been compared for alcohol preference (AP) many times. Maudsley rats from the North American Harrington derivation (MR/ Har) exhibit high AP under varying conditions [Adams N, Blizard DA (2002) Behav Genet 32:277– 299]. Whereas MR/Har females often show high AP acr...
متن کاملBurrow Use and the Influence of Ectoparasites in Brants’ Whistling Rat Parotomys brantsii
In Brants’ whistling rat, Parotomys brantsii, single animals inhabit unusually complex burrow systems containing several nest chambers. We investigated burrow use and examined the effect of ectoparasites on choice of alternative nest chambers by radiotelemetrically monitoring the nocturnal sleeping locations of individual whistling rats, before and after treating them to remove ectoparasites. P...
متن کاملThoughts before whistling.
Whistleblowing is a public alert by an insider of an organisation to a practice or concerning potential they observe in the organisation. This paper proposes that the risk, values at stake, timeliness and manner of complaint be considered before a whistle is blown. It also notes education and monitoring mechanisms.
متن کاملSocial common mole-rats enhance outbreeding via extra-pair mating.
Females in many species engage in matings with males that are not their social mates. These matings are predicted to increase offspring heterozygosity and fitness, and thereby prevent the deleterious effects of inbreeding. We tested this hypothesis in a cooperative breeding mammal, the common mole-rat Cryptomys hottentotus hottentotus. Laboratory-based studies suggested a system of strict socia...
