Nuclear war, beyond its devastating direct impacts, is expected to cause global climatic perturbations through injections of soot into the upper atmosphere. Reduced temperature and sunlight could drive unprecedented reductions in agricultural production, endangering global food security. [...]

11 p, 569.5 KB Regulation strength and technology creep play key roles in global long-term projections of wild capture fisheries / Scherrer, Kim J. N. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Many studies have shown that the global fish catch can only be sustained with effective regulation that restrains overfishing. However, the persistence of weak or ineffective regulation in many parts of the world, coupled with changing technologies and additional stressors like climate change, renders the future of global catches uncertain.

10 p, 1.1 MB Bioenergetic influence on the historical development and decline of industrial fisheries / Guiet, Jérôme (Universitat Autònoma de Barcelona.

Institut de Ciència i Tecnologia Ambientals) ; Cheung, William W. L. (University of British Columbia. Institute for the Oceans and Fisheries (Canada))
The global wild capture fishery expanded rapidly over the 20th century as fishing technology improved, peaking in the 1990s as most fisheries transitioned to fully- or over-exploited status. Historical records for individual large marine ecosystems (LMEs) tend to echo this same progression, but with local variations in the timing and abruptness of catch peaks. [...]

Under climate change, species composition and abundances in high-latitude waters are expected to substantially reconfigure with consequences for trophic relationships and ecosystem services. Outcomes are challenging to project at national scales, despite their importance for management decisions. [...]

23 p, 7.3 MB Assessing the role of high-frequency winds and sea ice loss on arctic phytoplankton blooms in an ice-ocean-biogeochemical model / Castro de la Guardia, Laura (University of Alberta.

Institut de Ciència i Tecnologia Ambientals) ; Myers, Paul (University of Alberta. Department of Earth and Atmospheric Sciences)
The long-term trend of increasing phytoplankton net primary production (NPP) in the Arctic correlates with increasing light penetration due to sea ice loss. However, recent studies suggest that enhanced stormy wind mixing may also play a significant role enhancing NPP. [...]

While the physical dimensions of climate change are now routinely assessed through multimodel intercomparisons, projected impacts on the global ocean ecosystem generally rely on individual models with a specific set of assumptions. [...]

13 p, 647.6 KB The fecal iron pump : global impact of animals on the iron stoichiometry of marine sinking particles / Le Mézo, Priscilla K. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
The impact of marine animals on the iron (Fe) cycle has mostly been considered in terms of their role in supplying dissolved Fe to phytoplankton at the ocean surface. However, little attention has been paid to how the transformation of ingested food into fecal matter by animals alters the relative Fe-richness of particles, which could have consequences for Fe cycling in the water column and for the food quality of suspended and sinking particles.

13 p, 2.4 MB Growth limitation of marine fish by low iron availability in the open ocean / Galbraith, Eric (Universitat Autònoma de Barcelona.

Atmospheric and Oceanic Sciences (USA)) ; Kroodsma, David (Global Fishing Watch (USA))
It is well-established that phytoplankton growth can be limited by the vanishingly low concentrations of dissolved iron found in large areas of the open ocean. However, the availability of iron is not typically considered an important factor in the ecology of marine animals, including fish. [...]

7 p, 3.6 MB Linking scaling laws across eukaryotes / Hatton, Ian (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Dobson, Andy P.

Institut de Ciència i Tecnologia Ambientals) ; Loreau, Michel (Centre National de la Recherche Scientifique. Station Eco Théorique Et Expérimentale (France))
Scaling laws relating body mass to species characteristics are among the most universal quantitative patterns in biology. Within major taxonomic groups, the 4 key ecological variables of metabolism, abundance, growth, and mortality are often well described by power laws with exponents near 3/4 or related to that value, a commonality often attributed to biophysical constraints on metabolism.
