Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
A “smart” tracer is a tracer that provides, directly or through measurement of its concentration or in combination with another compound, at least one “bit” more of information about the environment through which it travels than a conservative tracer. In this study we propose and present the chemical compound resazurin...
We propose the experimental use of resazurin (Raz) and develop a metabolically active transient storage (MATS) model to include processes that may provide additional information on transient storage from a biogeochemical perspective in stream ecosystems. Raz is a phenoxazine compound that reduces irreversibly to resorufin (Rru) in the presence of...
This conceptual paper explores the nexus between travel and learning; an area of investigation long neglected by tourism researchers. Using Aristotle’s concepts of phronesis, techne and episteme a framework for the major areas of literature dealing with touristic learning are considered and opportunities and challenges for expanding the boundaries of...
Excess NO₃⁻ in streams is a growing and persistent problem for both inland and coastal ecosystems, and denitrification is the primary removal process for NO₃⁻. Hyporheic zones can have high denitrification potentials, but their role in reach- and network-scale NO₃⁻ removal is unknown because it is difficult to estimate. We...
We investigated scaling of conservative solute transport using temporal moment
analysis of 98 tracer experiments (384 breakthrough curves) conducted in 44 streams
located on five continents. The experiments span 7 orders of magnitude in discharge
(10⁻ ³ to 10³ m³/s), span 5 orders of magnitude in longitudinal scale (10¹ to...

Harrya is described as a new genus of Boletaceae to accommodate Boletus chromapes,
a pink capped bolete with a finely scabrous stipe adorned with pink scabers, a chrome yellow
base, and a reddish brown spore deposit. Phylogenetic analyses of large subunit rDNA and
translation elongation factor 1α confirm Harrya as...
