Channel narrowing and vegetation development following a great plains flood Channel narrowing and vegetation development following a great plains flood
Streams in the plains of eastern Colorado are prone to intense floods following summer thunderstorms. Here, and in other semiarid and arid regions, channel recovery after a flood may take several decades. As a result, flood history strongly influences spatial and temporal variability in bottomland vegetation. Interpretation of these patterns must be based on understanding the long—term...

Kangaroo rat bone compared to white rat bone after short-term disuse and exercise Kangaroo rat bone compared to white rat bone after short-term disuse and exercise
Kangaroo rats (Dipodomys ordii) were used to study the effects of confinement on mechanical properties of bone with a long range objective of proposing an alternative to the white rat model for the study of disuse osteoporosis. Kangaroo rats exhibit bipedal locomotion, which subjects their limbs to substantial accelerative forces in addition to the normal stress of weight bearing. We...

Circulating levels of prolactin and progesterone in a wild population of red kangaroos (Macropus rufus) Marsupialia: Macropodidae Circulating levels of prolactin and progesterone in a wild population of red kangaroos (Macropus rufus) Marsupialia: Macropodidae
Circulating progesterone and prolactin levels were measured in shot and live-caught wild red kangaroos using radioimmunoassays validated for the red kangaroo. The objective of the study was to correlate hormone profiles with reproductive status and determine if red kangaroos follow the general pattern elucidated for other macropodids. During Phase 2a lactation (

Elk response to the La Mesa fire and current status in the Jemez Mountains Elk response to the La Mesa fire and current status in the Jemez Mountains
Faunal remains in local archeological sites and historic information suggest that elk populations in the Jemez Mountains were low from ca. 1200 A.D. through ca. 1900 A.D., when they were extirpated from this region. Elk were reintroduced to the Jemez country in 1948 and 1964- 1965, and their population apparently grew exponentially, reaching 1000 animals in the 1970's and about 7000 by...

Fire effects in southwestern forests: Proceedings of the Second La Mesa Fire symposium Fire effects in southwestern forests: Proceedings of the Second La Mesa Fire symposium
In 1977, the La Mesa Fire burned across 15,444 acres of ponderosa pine forests on the adjoining lands of Bandelier National Monument, the Santa Fe National Forest, and Los Alamos National Laboratory. Following this event, several fire effects studies were initiated. The 16 papers herein document longer-term knowledge gained about the ecological effects of the fire and about Southwestern...

Overview of La Mesa studies Overview of La Mesa studies
This 1994 Symposium on the La Mesa Fire reflects the efforts of the presenters and organizers to share some of the know ledge gained since 1977 about the ecological effects of the La Mesa Fire in particular, and Southwestern fire ecology in general. We are glad you came. We hope that you come away from this symposium with: 1) a greater understanding and appreciation for the varied and...

Milk composition in a field population of red kangaroos, Macropus rufus (Desmarest) (Macropodidae: Marsupialia) Milk composition in a field population of red kangaroos, Macropus rufus (Desmarest) (Macropodidae: Marsupialia)
The composition of milk from early pouch life (0-40 days) to weaning (360 days) was determined in samples collected from a field population of red kangaroos, Macropus rufus (n = 150). Total milk solids increased from 11% at 0-40 days to 26% at permanent emergence from the pouch (235 days), then decreased towards weaning. Compared with other macropodids, milk from red kangaroos is...
