2011, General and Comparative EndocrinologyCitation Excerpt :Again in the tammar, the concentration of P4 that was extracted from CL throughout pregnancy showed a direct correlation with the mass and stage of development of the CL (Renfree et al., 1979). Finally, in vitro secretion of P4 by luteal tissue was demonstrated in both the tammar (Hinds et al., 1983; Kojima et al., 1993) and the quokka (Bradshaw and Bradshaw, 1992). In the quokka, secretion of P4 from the CL was enhanced when the luteal tissue received perifusate from the remaining ovarian tissue, thus demonstrating co-operativity between the CL and the ovarian interstitial tissue (Bradshaw and Bradshaw, 1992).

2008, General and Comparative EndocrinologyCitation Excerpt :Considerable variation in time to ovulation occurs in eastern quoll (Hinds, 1989), which could account for the extended interval we observed. The pattern of plasma progesterone concentrations during the luteal phase (LP) in Tasmanian devils resembled that described for other non-macropodid marsupials (Tyndale-Biscoe and Renfree, 1987; Hinds, 1989; Hinds and Selwood, 1990; Bradshaw and Bradshaw, 1992; Millis et al., 1999; Johnston et al., 2000). The primary source of progesterone is the autonomous CL (Tyndale-Biscoe and Renfree, 1987; Hinds, 1990; Gemmell, 1995); and in the eastern quoll (Hinds, 1989) and brown antechinus (Hinds and Selwood, 1990) the major sustained increase in plasma progesterone during the LP mirrors CL development.
Reproduction and embryonic diapause in a marsupial: Insights from captive female Honey possums, Tarsipes rostratus (Tarsipedidae)
2007, General and Comparative EndocrinologyCitation Excerpt :We suggest that the later, and more sustained increase during the last 10 days of the cycle, represents the full functioning of the corpora lutea, as in other marsupials studied in this regard (Cake et al., 1980; Harder and Fleming, 1981; Tyndale-Biscoe and Hinds, 1981; Hinds and Tyndale-Biscoe, 1982; Walker and Gemmell, 1983; Gemmell et al., 1987; Fletcher, 1989; Hinds and Selwood, 1990; Jones and Rose, 1992). The lower levels prior to this may represent the output from slowly developing corpora lutea, or post-ovulatory follicles (Bradshaw and Bradshaw, 1992). Pregnancy, in our study, was complicated by the phenomenon of embryonic diapause.
