  abstract = {1. {T}he stress-gradient hypothesis ({SGH}) states that environmental stress modulates species interactions, causing a shift from negative interactions to net positive interactions with increasing stress. 2. {P}otentially, this modulation of species interactions could in turn influence biodiversity-ecosystem function ({B}-{EF}) relationships along stress gradients. {A}lthough the {SGH} has been extensively discussed in plant community ecology in the past two decades, it has received little attention from animal ecologists. 3. {T}o explore whether the {SGH} could be applied to animal communities, we conducted a litter decomposition experiment with aquatic detritivorous invertebrates in which we manipulated litter quality and measured species interactions along this resource quality gradient. {L}itter quality was manipulated by presenting detritivores with leaves of plant species varying in specific leaf area and decomposition rate in streams. 4. {W}e found a switch from negative to neutral interactions with increasing resource quality stress, in line with the {SGH}. {H}owever, by re-examining other published results with aquatic detritivores from the perspective of the {SGH}, we found that a diversity of patterns seem to characterize detritivore interactions along stress gradients. 5. {A}lthough the basic pattern proposed by the {SGH} may not apply to animal systems in general, we show that aquatic detritivore interactions do change along stress gradients, which underlines the importance of incorporating environmental stressors more explicitly in {B}-{EF} research.},
