Pinyon-juniper woodlands

Pinyon-juniper woodlands are one of the largest ecosystems in the Southwest and in the Middle Rio Grande Basin (Fig. 1). The woodlands have been important to the region's inhabitants since prehistoric times for a variety of natural resources and amenities. The ecosystems have not been static; their distributions, stand characteristics, and site...

Population biology of the Florida manatee

The Florida manatee (Trichechus manatus latirostris) is a unique element of the U.S. fauna. It is a distinct subspecies of the West Indian manatee (Domning and Hayek 1986) and one of the largest inshore mammals of the continent, reaching weights to 1,650 kg (Rathbun et al. 1990). Annual migratory circuits of some individuals through the...

An assessment of riparian environmental quality by using butterflies and disturbance susceptibility scores

The butterfly community at a revegetated riparian site on the lower Colorado River near Parker, Arizona, was compared to that found in a reference riparian site. Data indicated that the herbaceous plant community, which was lacking at the revegetated site, was important to several butterfly taxa. An index using butterfly sensitivity to habitat...

Are cicadas (Diceroprocta apache) both a "keystone" and a "critical-link" species in lower Colorado River riparian communities?

Apache cicada (Homoptera: Cicadidae: Diceroprocta apache Davis) densities were estimated to be 10 individuals/m2 within a closed-canopy stand of Fremont cottonwood (Populus fremontii) and Goodding willow (Salix gooddingii) in a revegetated site adjacent to the Colorado River near Parker, Arizona. Coupled with data drawn from the literature, I...

Ecological perspective: Linking ecology, GIS, and remote sensing to ecosystem management

Awareness of significant human impacts on the ecology of Earth's landscapes is not new (Thomas 1956). Over the past decade (Forman and Godron 1986, Urban et a1. 1987) applications of geographic information systems (GIS) and remote sensing technologies have supported a rapid rise in landscape.stale research. The heightened recognition within the...

Winter phytoplankton dynamics in a subalpine lake, Colorado, U.S.A

The temporal dynamics of phytoplankton were examined in The Loch, a subalpine lake in Rocky Mountain National Park, over the winter seasons of 1987-88 and 1988-89. The Loch was ice-covered from early November until early to mid May. The pattern of phytoplankton biovolume during ice-cover was consistent between the two years with maxima occurring...
