Waterfowl communities in the northern plains: Chapter 13 Waterfowl communities in the northern plains: Chapter 13
Features that determine the composition of avian communities have received extensive and enthusiastic attention, both empirically and theoretically (e.g., Cody 1974; Strong et al. 1984; Wiens, 1989a,b). Interspecific competition for limited resources is one influence widely regarded as critical, but others include species-specific responses to environmental conditions, predation...

Hydrological and thermal response of lakes to climate: Description and modeling Hydrological and thermal response of lakes to climate: Description and modeling
Lake systems continually respond to climatic conditions that vary over broad scales of space and time. The spatial distribution of lakes on the Earth’s surface is indicative of long-term patterns of atmospheric circulation, and the annual cycle of climate over lake basins is reflected in seasonal change in the size and temperature of lakes. Lake size is determined by the balance of water...

Modeling mangrove canopy reflectance using a light interaction model and an optimization technique Modeling mangrove canopy reflectance using a light interaction model and an optimization technique
At 20 sites, incorporating mixtures of black, red, and white mangroves, canopy reflectance spectra were derived from high resolution spectral data taken from a helicopter platform. Canopy characteristics were predicted from the canopy reflectance spectra by using measured and estimated data as inputs into a light-canopy interaction model within a optimization routine. Pertinent to...

Porphyry copper and other intrusion-related mineralization in Mexico Porphyry copper and other intrusion-related mineralization in Mexico
Intrusion-related copper-bearing ore deposits in Mexico span a wide-range of deposit types and geological settings and formed from the mid-Mesozoic through the Holocene. These deposits include world-class copper porphyry and skarn deposits as well as a continuum of similar skarn, porphyry, vein, and replacement deposits that contain variable quantities of molybdenum, zinc, silver, lead...

Geometry of sandy deposits at the distal edge of the Mississippi Fan, Gulf of Mexico Geometry of sandy deposits at the distal edge of the Mississippi Fan, Gulf of Mexico
Sidescan sonar provides a map of the seafloor that has greatly improved the understanding of depositional processes on modern deep-sea fans (e.g. Mutti and Normark 1991). Here, we present a sidescan-sonar mosaic from the eastern Gulf of Mexico that images the distal reaches of a channel on the Mississippi Fan and the deposits associated with it (Fig. 41.1). This area is one of several...
