Autor: Elisabeth von der Esch, Maria Lanzinger, Alexander J. Kohles, Christian Schwaferts, Jana Weisser, Thomas Hofmann, Karl Glas, Martin Elsner, Natalia P. Ivleva

Publikováno v: Frontiers in Chemistry, Vol 8 (2020)

In the environment the weathering of plastic debris is one of the main sources of secondary microplastic (MP). It is distinct from primary MP, as it is not intentionally engineered, and presents a highly heterogeneous analyte composed of plastic frag

Eastern boundary upwelling systems (EBUS) contribute a disproportionate fraction of the global fish catch relative to their size and are especially susceptible to global environmental change. Here we present the evolution of communities over 50 d in

Extracellular enzyme activity in the coastal upwelling system off Peru: a mesocosm experiment

Autor: Kristian Spilling, Jonna Piiparinen, Eric P. Achterberg, Javier Arístegui, Lennart T. Bach, Maria T. Camarena-Gómez, Elisabeth von der Esch, Martin A. Fischer, Markel Gómez-Letona, Nauzet Hernández-Hernández, Judith Meyer, Ruth A. Schmitz, Ulf Riebesell

The Peruvian upwelling system is a highly productive ecosystem with a large oxygen minimum zone (OMZ) close to the surface. In this work, we carried out a mesocosm experiment off Callao, Peru, with the addition of water masses from the regional OMZ c

Extracellular enzyme production in the coastal upwelling system off Peru during different upwelling scenarios: a mesocosm experiment

The Peruvian upwelling system is a highly productive ecosystem that could be altered by ongoing global changes. We carried out a mesocosm experiment off Peru, with the addition of water masses from the regional oxygen minimum zone (OMZ) collected at
