Two-dimensional habitat modeling in the Yellowstone/Upper Missouri River system Two-dimensional habitat modeling in the Yellowstone/Upper Missouri River system

This study is being conducted to provide the aquatic biology component of a decision support system being developed by the U.S. Bureau of Reclamation. In an attempt to capture the habitat needs of Great Plains fish communities we are looking beyond previous habitat modeling methods. Traditional habitat modeling approaches have relied on one-dimensional hydraulic models and lumped...

Book review: Riparian ecosystem recovery in arid lands: Strategies and references Book review: Riparian ecosystem recovery in arid lands: Strategies and references

Increasingly, ecosystem managers are attempting to restore riparian ecosystems in the arid West that have been degraded by land and water management practices. This book will fill a vacant niche in the library of these practitioners. Briggs emphasizes several concepts that should be fundamental to restoration projects but that too often are ignored. One of these central concepts is that...

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...
