Development of the science of riparian ecology in the semi-arid western United States [Chapter 1]

Publications Posted on: November 27, 2018
The science of riparian ecology in the West developed over several decades, especially in the Southwest and California, as the importance of this ecosystem, its components, productivity, functions, and relationship to system hydrology became better understood.

Riparian research and management: Past, present, future: Volume 1

Publications Posted on: November 19, 2018
Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume range from the more mesic northwestern United States to the arid Southwest and Mexico.

Inferring presence of the western toad (Anaxyrus boreas) species complex using environmental DNA

Publications Posted on: September 17, 2018
Western toads (species complex comprised of Anaxyrus boreas, A. canorus, A. exsul, and A. nelsoni) are widely distributed in the western United States but are declining, particularly in the southeastern extent of their range. The subspecies A. b. boreas is listed as a Species of Greatest Conservation Need in New Mexico, Colorado, Utah, and Wyoming.

Life histories of potamodromous fishes [Chapter 4]

Publications Posted on: April 12, 2018
Potamodromous fishes move and complete their life cycle entirely within freshwater. Myers (1949) proposed the term potamodromous to distinguish freshwater migratory fishes from diadromous fishes, which migrate between the sea and freshwater and oceanodromous fishes that migrate wholly within the sea. Diadromous fishes include anadromous, catadromous and amphidromous fishes (see Chapter 2, Morais and Daverat 2016).

Climate change and special habitats in the Blue Mountains: Riparian areas, wetlands, and groundwater-dependent ecosystems [Chapter 7]

Publications Posted on: April 14, 2017
In the Blue Mountains, climate change is likely to have significant, long-term implications for freshwater resources, including riparian areas, wetlands (box 7.1), and groundwater-dependent ecosystems (GDEs, box 7.2). Climate change is expected to cause a transition from snow to rain, resulting in diminished snowpack and shifts in streamflow to earlier in the season (Leibowitz et al. 2014, Luce et al. 2012; see chapter 3).

Fish and other aquatic resource trends in the United States: a technical document supporting the Forest Service 2010 RPA Assessment

Publications Posted on: August 14, 2012
The Forest and Rangeland Renewable Resources Planning Act (RPA) of 1974 requires periodic assessments of the status and trends in the Nation's renewable natural resources including fish and other aquatic species and their habitats. Data from a number of sources are used to document trends in habitat quality, populations, resource use, and patterns of imperilment among aquatic fauna.
