Book ChapterDOI
Fatty acid trophic markers in the pelagic marine environment.
TL;DR: A conceptual model of the spatial and temporal dominance of group-specific primary producers, and hence the basic fatty acid patterns available to higher trophic levels is presented and is based on stratification.
Journal ArticleDOI
Effects of climate and overfishing on zooplankton dynamics and ecosystem structure: regime shifts, trophic cascade, and feedback loops in a simple ecosystem
TL;DR: Mollmann et al. as discussed by the authors investigated the role of zooplankton and fish trophic changes in a brackish waterbody in the Central Baltic Sea.
Journal ArticleDOI
Baltic cod recruitment – the impact of climate variability on key processes
Friedrich W. Köster,Christian Möllmann,Hans-Harald Hinrichsen,Kai Wieland,Jonna Tomkiewicz,Gerd Kraus,Rüdiger Voss,Andrei Makarchouk,Brian R. MacKenzie,Michael St. John,Dietrich Schnack,Norbert Rohlf,Tomasz Linkowski,Jan Beyer +13 more
TL;DR: The present study aims at disentangling the interactions between reproductive effort and hydrographic forcing leading to variable recruitment in the eastern Baltic cod stock using updated environmental and life stage-specific abundance and production time-series.
Journal ArticleDOI
End-To-End Models for the Analysis of Marine Ecosystems: Challenges, Issues, and Next Steps
Kenneth A. Rose,J. Icarus Allen,Yuri Artioli,Manuel Barange,Jerry Blackford,Francois Carlotti,Roger Allan Cropp,Ute Daewel,Karen P. Edwards,Kevin J. Flynn,Simeon L.

Lan Smith,Caleb Smith,Cosimo Solidoro,Michael St. John,Meng Zhou +25 more
TL;DR: End-to-end modeling is in its early developmental stages and thus presents an opportunity to establish an open-access, community-based approach supported by a suite of true interdisciplinary efforts.
Journal ArticleDOI
A Dark Hole in our Understanding of Marine Ecosystems and their Services: Perspectives from the mesopelagic community.
Michael St. John,Ángel Borja,Guillem Chust,Michael R. Heath,Ivo Grigorov,Adrian Martin,Ricardo S. Santos,Patrizio Mariani +7 more
TL;DR: In the face of increasing anthropogenic pressures acting on the Earth system, urgent actions are needed to guarantee efficient resource management and sustainable development for our growing human population as mentioned in this paper, which can directly impact upon food security and the wellbeing of humanity.
