Kid production by marked females, age ratios from a 24-year study, and the literature are used to evaluate hypotheses that three intrinsic and three extrinsic factors affect reproduction by female Rocky Mountain goats (Oreamnos americanus). On Sheep Mountain – Gladstone Ridge, Colorado, mountain goat age ratios declined while the herd grew during 1966–1979, and continued to decline with population stability during 1980–1989, suggesting a continued increase in ecological density of goats 39 years after they were introduced in 1950. Among intrinsic factors, age and persisting individual characteristics have influenced reproductive success of females. Reproductive success in any year has not limited success in the following year, except in 4-year-olds. Among extrinsic factors, reproductive success of female mountain goats has been negatively influenced by density or ecological density and by snowpack during gestation. Reproductive success of females may have been positively influenced by snowpack that enhanced forage conditions prior to breeding. The relative importance of these six factors in determining reproductive success of females may vary among and (temporally) within herds. Most hypotheses regarding reproductive success in female mountain goats remain poorly tested. Short-term observational studies hold little promise for testing hypotheses, owing to large among-years variation in reproductive success. Long-term, intensive observational studies, or manipulative experiments, are suggested.

Selenium levels and glutathione peroxidase (GSH-Px) activity were determined in the blood of wild and captive herds of bighorn sheep (Ovis canadensis), as well as in one wild mountain goat (Oreamnos americanus) herd. No significant relationship was established between blood selenium and GSH-Px activity for individual herds of bighorns, but when all herds were pooled, selenium was significantly (P < 0.01) correlated with GSH-Px. The hypothesis that bighorn sheep would exhibit higher GSH-Px activity per unit of blood selenium than domestic cattle was not supported. One bighorn population had blood selenium levels below those considered deficient in domestic sheep, yet exhibited no clinical signs of selenium deficiency. A blood selenium by GSH-Px relationship did not exist for the single mountain goat herd sampled. The seven blood samples collected from mountain goats did not differ from those from bighorn sheep in their GSH-Px activity relative to blood selenium levels.

Trench Area

Mountain goats (Oreamnos americanus) occupying the Rocky Mountain Trench area of southeastern British Columbia use natural earth licks in the spring (males) and early summer (females). Analysis of range vegetation reveals a low sodium content (mean about 0.004% dry weight). Despite low sodium intake from feed, blood sodium values were normal (m = 150.8 meq/liter). Loss of sodium via the fecal route increases abruptly in the spring. This period of increased loss corresponds with the lime of use of the natural licks. Mineral constituents of the licks were Ca (1050–85 000 ppm), P (0–25 ppm), and Na (115–5500 ppm). Each animal visited the lick but once during the summer and did so despite increased exposure to hazards of predation. Despite the low soil sodium content the inference is that the goats are eating the earth to compensate for Na deficiency.

A New Species

An oxyurid nematode of the genus Skrjabinema Wereschtschagin, 1926 is recorded from the Columbian mountain goat and mountain caribou in Canada. This parasite is the first Canadian and second North American record for the genus and is described as a new species. A key to the species of Skrjabinema is included.

Milk was obtained from a mountain goat that was killed near Haines Junction, Yukon, and from another that was killed near Taseko Lake, B.C. The gross composition of the milks and the fatty acid constitution of the milk fats were determined.
