ABSTRACT: Wading birds are important predators in intertidal communities. Their ecology anddistribution have been widely studied in estuarine wetlands, but little is known about the factorsdetermining their abundance and diversity in the more common non-estuarine coasts.

SUMMARY1. Periphyton chlorophyll a (chl a), ash‐free dry mass, taxonomic composition, and cellular and water‐column nutrients were analysed every 4 weeks for a year at sixteen stream sites in New Zealand. The hypothesis was investigated that broad‐scale differences in mean monthly periphyton development are defined primarily by the frequency of flood ...

Journal of Geophysical Research: Solid Earth, 2020
AbstractGeomagnetic storms can cause power grid instabilities and blackouts due to excessive geomagnetically induced currents (GICs) flowing in electric transmission systems. In this study, we assess regional vulnerability to GICs by modeling the geoelectric fields induced by significant historic geomagnetic disturbance events in the presence of 3D ...

Impacts on seafloor geology of drilling disturbance in shallow waters
Environmental Monitoring and Assessment, 2010This paper describes the effects of drilling disturbance on the seafloor of the upper continental slope of the Campos Basin, Brazil, as a result of the project Environmental Monitoring of Offshore Drilling for Petroleum Exploration--MAPEM. Field sampling was carried out surrounding wells, operated by the company PETROBRAS, to compare sediment ...

Abstract: Boreal wetlands are recognized as important wildlife habitats, especially as breeding and staging grounds for a large number of waterfowl. The main objectives of this study were to quantify the distribution of wetland and aquatic wildlife-habitat landscape types within boreal Quebec and to determine how such recognizable wildlife habitats ...

Geology of Disturbed Belt of Southeastern Idaho: ABSTRACT
AAPG Bulletin, 1954The Disturbed Belt of southeastern Idaho is located on the eastern edge of the Cordilleran geosyncline. The structure and stratigraphy are quite similar to that found along the eastern edge of the Cordilleran geosyncline from Canada to southern Nevada.

Structural geology of the Sawtooth Range at Sun River Canyon, Montana Disturbed Belt, Montana
1987Abstract The Sawtooth Range is located in northwest Montana in parts of Pondera, Teton, and Lewis and Clark counties. The range is part of the Rocky Mountain fold and thrust belt, or Disturbed Belt, and lies between Glacier National Park to the north and the Helena salient to the south.
