  • The analysis of food web properties under different environmental conditions informs us how the ecosystem functions. Here, Tunneyet al. use post-glacial lakes as model ecosystems to show how macroscopic patterns of food webs vary with changes in habitat and resource accessibility.

  • Species richness patterns are driven by biotic and abiotic factors, the relative strengths of which are unclear. Here, the authors test how species interactions or environmental traits influence fish richness across over 700 Canadian lakes, showing a surprisingly small role of negative interactions.

  • A synthesis of empirical and theoretical literature shows the extent to which food production has homogenized and rewired food webs to increase productivity but with negative consequences for stability.

  • Analyses of a long term fishery-independent trawl survey dataset reveal substantial loss of trawlable biomass and shift in community structure in a marine ecosystem, with little signs of recovery.

  • Climate change is spatially asymmetrical and so will alter the behaviour of generalist consumer species, affecting food webs in two ways. Movement into novel ecosystems will affect the topology of food webs, while changes within an ecosystem will affect interaction strengths.
