Cocopah identity and cultural survival: Indian gaming and the political ecology of the lower Colorado River delta, 1850-1996
… the ways in which the political ecology of the Colorado River have influenced Cocopah identity. In approaching Cocopah identity from a political ecology perspective, it is argued that the federal bureaucracy's criteria for tribal status and the recognition of individuals as belonging to …

First-year growth and survival of habitat revegetation trials on the lower Colorado River, Mexico
Sweeping changes across the Colorado River watershed in the 20th century resulted in near-complete collapse of the natural communities in the Colorado River Delta (CRD) in Mexico. A brief return of freshwater flows in the 1980s and 1990s showed the riparian corridor remains resilient to past …

HABITAT USE AND THE EFFECTS OF DISTURBANCE ON WINTERING BIRDS USING RIPARIAN HABITATS IN SONORA, MEXICO
… undisturbed and highly disturbed sites at three river systems in Sonora. There is, in general, little effect of disturbance on the composition of wintering communities, with less than 20% of the most common species having significant differences in their abundances between relatively undisturbed …

Cyclically-Forced Hyperpycnites of the Ancient Colorado River Proximal Prodelta
<p>Prodeltaic deposits record a distal, minimally reworked archive of dominant processes active at the fluvial-marine interface. The Fish Creek-Vallecito Basin (CA, US) preserves an ~3 km-thick, lower Pliocene, progradational deltaic succession formed when the ancestral Colorado River infiltrated …
