Ananlysis of gonadotrophin-releasing hormone-1 and kisspeptin neuronal systems in the nonphotoregulated seasonally breeding eastern rock elephant-shrew (Elephantulus myurus)
Medger, K.; Bennett, N.C.; Chimimba, C.T.; Oosthuizen, M.K.; Mikkelsen, J.D.; Coen, C.W. (Wiley Periodicals Inc., 2018)Of the 18 sub-Saharan elephant-shrew species, only eastern rock elephant-shrews reproduce seasonally throughout their distribution, a process seemingly independent of photoperiod. The present study characterizes gonadal ... -
Is reproduction of male eastern rock sengis (Elelphantulus myurus) from southern Africa affected by photoperiod
Medger, K.; Chimimba, C.T.; Bennett, N.C. (NRC Research Press, 2016)Many mammals use the change in day length to time physiological and behavioural activities on a seasonal basis. Particularly, mammals from temperate regions use photoperiod to regulate reproductive functions; however, ... -
Reproductive photoresponsiveness in male spiny mice from South Africa
Medger, K.; Chimimba, C.T.; Bennett, N.C. (Zoological Society of London, 2012)Many seasonally breeding mammals use changes in photoperiod as a reliable cue to time reproduction. Photoperiodic timing assists an animal in predicting annual environmental changes in its habitat and therefore, enables ... -
Seasonal changes in reproductive development in male spiny mice (Acomys spinosissimus) from South Africa
Medger, K.; Chimimba, C.T.; Bennett, N.C. (Elsevier, 2012)Seasonal reproduction is a common characteristic of many small mammals which inhabit seasonal environments in temperate regions, the sub-tropics as well as the tropics. It is important for an animal to reproduce during ... -
Seasonal reproduction in the eastern rock elephant-shrew: Influenced by rainfall and ambient temperature?
Medger, K.; Chimimba, C.T.; Bennett, N.C. (Zoological Society of London, 2012)Because environmental conditions vary seasonally in most regions, many small mammals reproduce at a specific time of the year to maximize their reproductive success. In the tropics and subtropics, the breeding season is ... -
Seasonal reproduction in the female spiny mouse from South Africa
Medger, K.; Chimimba, C.T.; Bennett, N.C. (The Zoological Society of London, 2010)Many mammal species reproduce seasonally because of annual fluctuations in temperature, rainfall and photoperiod in often nutritionally challenging habitats. The reproductive biology of many small southern African mammals ...
