Transferrin Polymorphism

A number of polymorphisms involving characteristics of the blood have been described in Australian marsupials, but the genetical control of these has been established only for variation in the iron-binding serum protein transferrin in the red kangaroo Macropus rufus (Desmarest) (= Megaleia rufa) (Cooper and Sharman 1964), and the eastern and western grey kangaroos Macropus giganteus (Shaw) and Macropus fuliginosus (Desmarest) (Kirsch and Poole 1967). Transferrin variation in the brush-tail possum Trichosurus vulpecula (Kerr), first detected by Kirsch (personal communication), is being studied in this laboratory. The inheritance of the protein patterns developed on a starch gel after electrophoresis may be ascribed to the actions of two or more autosomal allelic genes without dominance.

Australian Marsupial

The reproductive tracts of males from eight species of Australian marsupial were examined (Macropus eugenii, Potovous tridactyhs, Sminthopsis crassicaudata, Antechinus stuartii, Pseudocheirus peregrinus, Trichosurus vulpecula, Isoodon macrourus, and Perameles nasuta). The prostate glands of these species were found to be of two shapes, carrot-like or heart-like. From one to three pairs of Cowper's glands were observed; these were mostly bulbous in shape but some were kidney-shaped. Both prostate and Cowper's glands were tubular in structure with the glandular tubules lined by a simple columnar epithelium. The glandular tubules of Cowper's glands were of much larger diameter than those of the prostate. The prostate glands were segmented, and this segmentation was usually shown by variations in the height and staining reactions of the tubular epithelium and in the volume of connective tissue between glandular tubules. Differences in microanatomy between pairs of Cowper's glands were far less than those between prostate segments. Mucosubstance appeared to be the major contribution of the prostate to the seminal plasma. This mucosubstance was mainly neutral, with glycogen largely absent. The present results indicate that the Cowper's glands secrete mucus but that various glands also contributed lipid and glycogen.

We measured daily changes in plant water content to see if red kangaroos (Macropus rufus), in foraging at night, may gain more water than foraging by day. If so, it could be influential in dictating their time of foraging. The study was stimulated by work in Africa which showed that, by choosing to feed at night, gazelles are able to take advantage of increased plant water content. Daily changes in water content of 15 known forage plants were examined at Idalia National Park in semi-arid western Queensland in February, April and July 2002, during progressive drying of the country in an extraordinarily dry year. Of 29 day-night comparisons of plant water content, thirteen showed no difference, two (both of red spinach, Trianthema triquetra) showed a substantial increase at night, eight showed small but statistically significant increases, and six showed small but statistically significant decreases. We conclude that the choice of red kangaroos to forage at night is unlikely to be explained by nightly increases in plant water content.

Lactating Females

The kangaroo populations of Kinchega National Park respond differently to shifts in pasture productivity, red kangaroos Macropus rufus being mobile and unevenly distributed with respect to soil and vegetation types, by comparison with the more evenly dispersed western grey kangaroos M. fuliginosus and the sedentary and localized euros M, robustus erubescens. Red kangaroo population classes tend to be differentially distributed, so that large males and heavily lactating females predominate on the seasonally preferred pastures, while other classes tend to predominate elsewhere. This finding has several implications for the management of red kangaroos and for our understanding of their resource ecology and mating systems.

By the use of starch gel electrophoretic technique the muscle myogens of the five Pacific west coast species of the Oncorhynchus genus, the steelhead trout (representative of the genus Salmo), the lingcod, and Atlantic cod have been separated. The characteristic protein patterns were used to group the members of the Oncorhynchus genus into sockeye, pink, and chum salmon on the one hand and the spring and coho salmon on the other. Correlation of the groupings based upon their protein pattern is discussed in relation to a similar grouping arrived at through behavior studies by other workers. The relationship between column and gel electrophoretic separations has been investigated.
