It has been suggested that differences in body size between consumer and resource species may have important implications for interaction strengths, population dynamics, eventually food web structure, function, evolution. Still, the general distribution of consumer–resource body-size ratios real ecosystems, whether they vary systematically among habitats or broad taxonomic groups, is poorly understood. Using a unique global database on sizes, we show mean aquatic herbivorous detritivorous...
While the physical dimensions of climate change are now routinely assessed through multimodel intercomparisons, projected impacts on global ocean ecosystem generally rely individual models with a specific set assumptions. To address these single-model limitations, we present standardized ensemble projections from six marine forced two Earth system and four emission scenarios without fishing. We derive average biomass trends associated uncertainties across food web. Without fishing, mean...
Existing methods to predict the effects of climate change on biomass and production marine communities are predicated modelling interactions dynamics individual species, a very challenging approach when distributions changing little is known about ecological mechanisms driving responses many species. An informative parallel develop size-based methods. These capture properties food webs that describe energy flux at particular size, independent species' ecology. We couple...
Changing temperature can substantially shift ecological communities by altering the strength and stability of trophic interactions. Because many rates are constrained temperature, new approaches required to understand how simultaneous changes in multiple alter relative performance species their We develop an energetic approach identify relationship between biomass fluxes standing across levels. Our links dynamics measure temperature-dependent interactions determine these food web stability....
Abstract Societal, economic and scientific interests in knowing where biodiversity is, how it is faring what can be done to efficiently mitigate further loss the associated of ecosystem services are at an all‐time high. So far, however, monitoring has primarily focused on structural compositional features ecosystems despite growing evidence that functions key elucidating mechanisms through which biological diversity generates humanity. This gap traced current lack consensus exactly track...
Projections of climate change impacts on marine ecosystems have revealed long-term declines in global animal biomass and unevenly distributed fisheries. Here we apply an enhanced suite ecosystem models from the Fisheries Marine Ecosystem Model Intercomparison Project (Fish-MIP), forced by new-generation Earth system model outputs Phase 6 Coupled (CMIP6), to provide insights into how projected will affect future ocean ecosystems. Compared with previous generation CMIP5-forced Fish-MIP...
Abstract Climate change effects on marine ecosystems include impacts primary production, ocean temperature, species distributions, and abundance at local to global scales. These changes will significantly alter ecosystem structure function with associated socio‐economic services, fisheries, fishery‐dependent societies. Yet how these may play out among basins over the 21st century remains unclear, most projections coming from single models that do not adequately capture range of model...
Previous reconstructions of marine fishing fleets have aggregated data without regard to the artisanal and industrial sectors. Engine power has often been estimated from subsets developed world, leading inflated results. We disaggregated into three sectors, (unpowered/powered) industrial, reconstructed evolution fleet its effort. found that global doubled between 1950 2015-from 1.7 3.7 million vessels. This driven by substantial expansion motorized fleet, particularly, powered-artisanal...
Abstract The diverse aquaculture sector makes important contributions toward achieving the Sustainable Development Goals (SDGs)/Agenda 2030, and can increasingly do so in future. Its role for food security, nutrition, livelihoods, economies, cultures is not clearly visible Agenda 21 declaration. This may partly reflect state of development policies compared with its terrestrial counterpart, agriculture, possibly also because production has historically originated from a few key hotspot...
