[1] Most estimates of diffusive flux (F) of methane (CH4) and carbon dioxide (CO2) from lakes are based on single-point flux chamber measurements or on piston velocity (k) modeled from wind speed and single-point measurements of surface water gas concentrations (Caq). We analyzed spatial variability of F of CH4 and CO2, as well as Caq and k in 22 European lakes during late summer. F and k were ...

Lake Van is the largest saline soda lake in world and one of world’s few endorheic lakes greater than 3,000 km 2 surface area. Despite its huge size, no fish species have so far been known to permanently occur this due extreme environmental conditions. Here, we report discovery a population that inhabits some unique microbialites lake, at maximum depth 13 m about 500 offshore. We tested whether...

The elimination of triamcinolone acetonide after intra-articular administration varied widely among horses. Detection of triamcinolone in plasma samples from horses on day 10 post-triamcinolone acetonide administration suggests careful use of this drug before performance. Authors’ addresses: K.L. Maddy Equine Analytical Chemistry Laboratory, University of California, West Health Science Drive, ...

Ships, which are the essential elements of maritime transportation, have an indispensable role in world freight and passenger transportation. Besides sea routes, played by ships inland water transport is also very important. In addition to these important economic effects, a major pollutant source. These emissions negative effects on human health, cities, environment, as well causing atmospheri...

The Sustainable Development Goals (SDGs) are aimed to provide a comprehensive framework for all economies /industries work toward more prosperous and environmentally friendly future. Maritime transport its subsectors like Inland Waterway Transportation (IWT) needed attain most SDGs. Thus, it must raise awareness of how the marine industry, sub-sectors, scientific research contribute SDG achieve...

Population genetic compositions of the three largest spawning groups of Lake Erie walleyes Sander vitreus (Maumee River, Sandusky River, and Van Buren Bay reefs) were tested for temporal and spatial consistency across 14 years using nine nuclear DNA microsatellite loci from 726 adult walleyes collected in 1995, 1998, 2003, 2007, and 2008. Previous genetic work focused on a one-time “snapshot”; ...

Phosphate uptake capacity of natural phytoplankton populations was used as a physiological indicator of P limitation in the Loosdrecht lakes. During a substantial period of the growth season of 1983, P-limited growth was observed in Lake fireukeleveen and Lake Loosdrecht, but P limitation was less severe in the latter. In Lake Breukeleveen the maximum initial phosphate uptake rate (V,,) varied ...
