-> 2) #Invasivespecies are not necessarily bad for local communities! Our findings challenges the conventional wisdom that #invasivespecies are usually harmful and lead to the #extinctions and #collapses of local communities.

The trophic position of #invasivespecies (as #predator or #prey), the #sizes of local and invasive species & the abiotic conditions play a key role for invasion success -> 1) #Warming and #eutrophication are likely to accelerate invasions of smaller species!

-> Energetic Imbalances in #freshwater communities may disrupt the food webs, causing sudden population collapses & cascade extinction.

Our model highlights a diversity of potential collapses that may happen in freshwater systems in response to energetic imbalances in multichannel food webs

-> A ‘symmetry in asymmetries’ is critical to maintain multichannel food webs through two compensatory levels of asymmetry that modulate the energy flows in the different food web channels

We show that a ‘symmetry in asymmetries’ is critical to maintain multichannel food webs through two compensatory levels of asymmetry (i.e., competitive abilities of the consumers and their vulnerability to predation) that modulate the energy flows in the different food web channels
