In early summer 1995, we surveyed total system metabolism in the Plum Island estuary. Objectives included (1) estimation of ecosystem metabolism via open-water oxygen measurements, (2) determination of the autotrophic and heterotrophic regions of the estuary, and (3) comparison of the loading of organic carbon from the watershed to measurements of autochthonous production. Metabolism was calcul...

Integration of ichnologic, sedimentologic, and stratigraphic studies of cores from Lower Pennsylva-nian oil and gas reservoirs (lower Morrow Sandstone, southwest Kansas) allows researchers to distinguish between estuarine-and open-marine deposits. This study represents one of the first published ichnologic analyses of a Paleozoic reservoir and, therefore, provides a unique opportunity to test t...

This study focused on the influence of local-scale environmental factors on key metrics of fish community structure and function at Guanabara Bay, an estuarine system that differs from all other south-western Atlantic estuaries due to the influence of an annual low-intensity upwelling event during late spring and summer, between November and March, when a warm rainy climate prevails. The spatia...

Biological degradation of cyanobacterial hepatotoxin microcystins in estuarine and coastal water samples from the Patos Lagoon estuarine system, a coastal lagoon situated at the southernmost region of Brazil, was observed. Samples of natural surface water were spiked with purified and semi-purified microcystins (MC-LR and [D-Leu(1)]MC-LR) and their concentrations were monitored by HPLC analysis...

INTRODUCTION Questionnaires to evaluate hand function are variable in the number of items, domains and diseases in which they had been previously used. OBJECTIVES a) To translate to Spanish and validate the m-SACRAH and AUSCAN questionnaires; b) to do a transcultural adaptation of DASHe, previously validated in Spain), and c) to compare them and the Cochin questionnaire (previously validated ...
