Relative Effects of Eutrophication and Warming on Freshwater Ecosystems Across Ecological Levels. [PDF]

open access: yesGlob Chang Biol
This experimental study explores the effects of global change on different ecological levels. We demonstrate that warming primarily impacts lower ecological levels, such as community composition, whereas eutrophication predominantly affects the most integrative ecological level, that is, ecosystem.

Effects of competition and predation risk from a life history intraguild predator on individual specialisation. [PDF]

open access: yesJ Anim Ecol
Individual niche specialisation is widespread within animal populations and can have important ecological consequences. Predation and competition are known drivers of individual specialisation, but their combined effects are unstudied. This mesocosm experiment shows that competition and predation from a single antagonist can have variable effects on ...

Procambarus virginalis Lyko, 2017: A new threat to Iberian inland waters. [PDF]

open access: yesEcol Evol
We provide the first record of Procambarus virginalis in the Iberian Peninsula, based on morphological and genetic evidence (molecular barcoding of COI). We discuss its most plausible introduction pathways, update its global geographical distribution, highlight the potential impacts if it becomes invasive in Iberia and recommend some proposal ...
