Ecology and behaviour of the Alder Flycatcher Empidonax alnorum, Tyrannidae in winter Ecology and behaviour of the Alder Flycatcher Empidonax alnorum, Tyrannidae in winter
The Alder Flycatcher Empidonax alnorum (Tyrannidae) winters from Colombia and Venezuela, south to northern Argentina. We studied the species in Manu National Park, Madre de Dios, Peru. In this area the species occupies riparian zones along lowland meander rivers as well as adjacent transition zone forest in the floodplain. These habitats have a number of age-related longitudinal zones...

Physical properties of sediments from the JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well Physical properties of sediments from the JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well
A 1150 m deep gas hydrate research well was drilled in the Canadian Arctic in February and March 1998 to investigate the interaction between the presence of gas hydrate and the natural conditions presented by the host sediments. Profiles of the following measured and derived properties are presented from that investigation: water content, sediment wet bulk density, grain size, porosity...

Enhancement of anti-Aeromonas salmonicida activity in Atlantic salmon (Salmo salar) macrophages by a mannose-binding lectin Enhancement of anti-Aeromonas salmonicida activity in Atlantic salmon (Salmo salar) macrophages by a mannose-binding lectin
We investigated the effects of a calcium-dependent mannose-binding lectin isolated from the serum of Atlantic salmon on Aeromonassalmonicida viability and the anti-A. salmonicida activity of Atlantic salmon macrophages. In the absence of other factors, binding of this lectin at concentrations of 0.8, 4.0 and 20.0 ng ml−1 to virulent A. salmonicida failed to significantly reduce (P>0.05)...

Biochemical and molecular typing of Streptococcus iniae isolated from fish and human cases Biochemical and molecular typing of Streptococcus iniae isolated from fish and human cases
Streptococcus iniae is an important bacterial pathogen of fish, causing up to 50% mortality in stocks, which has recently been associated with human infections. To determine whether S. iniae isolates from humans and fish are similar, the present authors examined the biochemical profiles and genetic relatedness of these isolates by random amplified polymorphic DNA (RAPD) analysis and...

Metabolic rates in an anadromous clupeid, the American shad (Alosa sapidissima) Metabolic rates in an anadromous clupeid, the American shad (Alosa sapidissima)
To assess the energetics of migration in an anadromous fish, adult American shad (Alosa sapidissima) were swum in a large respirometer at a range of speeds (1.0–2.3 body lengths (BL) s−1, 13–24 °C). Metabolic rate (MO2) was logarithmically related to swimming speed (Bl s−1; r2 = 0.41, slope = 0.23 ± 0.037) and tailbeat frequency (beats × min−1; r2 = 0.52, slope = 0.003 ± 0.0003)...

Water Resources Data: New Jersey, Water Year 1998, Volume 1, Surface-Water Data Water Resources Data: New Jersey, Water Year 1998, Volume 1, Surface-Water Data
This volume of the annual hydrologic data report of New Jersey is one of a series of annual reports that document hydrologic data gathered from the U.S. Geological Survey's surface- and ground-water data-collection networks in each State, Puerto Rico, and the Trust Territories. These records of streamflow, ground-water levels, and water quality provide the hydrologic information needed...

COMDYN: Software to study the dynamics of animal communities using a capture-recapture approach COMDYN: Software to study the dynamics of animal communities using a capture-recapture approach
COMDYN is a set of programs developed for estimation of parameters associated with community dynamics using count data from two locations or time periods. It is Internet-based, allowing remote users either to input their own data, or to use data from the North American Breeding Bird Survey for analysis. COMDYN allows probability of detection to vary among species and among locations and...
