Effects of Photoperiod on Epididymal and Sperm Morphology in a Wild Rodent, the Viscacha (Lagostomus maximus maximus)
The viscacha (Lagostomus maximus maximus) is a seasonal South American wild rodent. The adult males exhibit an annual reproductive cycle with periods of maximum and minimum gonadal activity. Four segments have been identified in the epididymis of this species: initial, caput, corpus, and cauda. The main objective of this work was to relate the seasonal morphological changes observed in the epid...

متن کاملProbable effect of photoperiod on seasonal variation in the nuclear volume of the adrenal cortex of viscacha (Lagostomus maximus maximus).
The neuroendocrine system regulates several organic functions such as reproduction, metabolism and adaptation to the environment. This system shows seasonal changes linked to the environment. The experimental model used in the present study was Lagostomus maximus maximus (viscacha). The reproduction of males of this species is photoperiod dependent. Twenty-four adult male viscachas were capture...

متن کاملMilk composition in the plains viscacha (Lagostomus maximus).
Milk samples were taken from 10 plains viscacha between 9 and 64 days post partum. Mean concentrations (+/- s.e.) were 17 +/- 1.1 mM-Na; 32 +/- 1.6 mM-K; 35 +/- 2.2 mM-Cl; 116 +/- 3.3 mM-lactose (total reducing sugar) (all in 8 samples); less than 10-220 mg citrate/l (range of 4 samples); 15.7 +/- 0.64 g total nitrogen/l (3 samples). The Na:K ratio was 1:1.95 +/- 0.17. It was estimated that the...
