Colonization by nearshore fish on small artificial reefs in Barkley Sound, British Columbia
TLDR
The structure of a temperate nearshore fish community is investigated by examining the development of fish assemblages on small artificial reefs of concrete blocks constructed in two series 6 months apart, where a species equilibrium was rapidly reached within 6 months.
Quaternary geologic map of the Vicksburg 4° x 6° quadrangle, United States
NOTE: This map is the product of collaboration of State geological surveys, universities, and the U.S. Geological Survey, and is designed for both scientific and practical purposes. It was prepared
CONTRASTING HABITAT ASSOCIATIONS OF SAGEBRUSH-STEPPE SONGBIRDS IN THE INTERMOUNTAIN WEST.
TLDR
It is suggested that the three sagebrush obligates are best conserved by promoting shrublands over a broad range of elevations, containing both sagebrush and other shrubs in patches of mixed height, and minimizing invasive annual grasses.
STORM WATER RUNOFF QUALITY FROM THREE LAND-USE AREAS IN SOUTH FLORIDA1
: Storm water runoff studies of three small basins (20, 40, and 58 acres) in the Fort Lauderdale area of Florida were conducted by the U.S. Geological Survey in 1974–78. The basins were homogeneously
Effects of Prey Abundance on Breeding Season Diet of Northern Goshawks (Accipiter gentilis) Within an Unusual Prey Landscape
TLDR
The diet of Northern Goshawks was low in diversity, with high overlap among nests, indicating a strong local dependence on the dominant food item, and the proportion of mammalian prey in the diet was greater in larger broods than in smaller broods.
Erratum: Space utilization in a community of temperate reef fishes inhabiting small experimental artificial reefs
TLDR
Only Sebastes melanops showed consistent shifts in its space use in response to increases in the density of the other members of the community, indicating that, with this exception, interspecific competition was probably a weak force in this system.
Drip application of nitrogen is efficient
TLDR
The goal is to develop cultural practices by which crop nutrient needs are satisfied by maximum uptake from a minimum quantity of applied fertilizer.
