General understanding of freshwater positive interactions has been far
outpaced by knowledge of these important relationships in terrestrial and
marine ecosystems. Positive interactions are sensitive to human impacts,
necessitating synthetic approaches to elucidate broad patterns and predict
future changes if these interactions are altered or lost. We conducted a
global meta-analysis to evaluate the magnitude of positive interactions
across freshwater habitats. In 340 studies, we found substantial positive
effects, with facilitators increasing beneficiaries by, on average, 81%
across all taxa and response variables. Mollusks in particular were
commonly studied as both facilitators and beneficiaries. Amphibians were
one group benefiting the most from positive interactions, yet amphibians
were not commonly studied. Invasive facilitators had stronger positive
effects on beneficiaries than native facilitators. We compared positive
effects between high and low stress conditions (n = 13) and found no
difference in the magnitude of benefit. Future areas of research include
understudied facilitators and beneficiaries, the stress gradient
hypothesis, patterns across space or time, and the influence of declining
taxa whose elimination would jeopardize fragile positive interaction
networks. Freshwater positive interactions occur among a wide range of
taxa, influence populations, communities, and ecosystem processes, and
deserve further exploration
Please see readME.txt for associated metadata. The attached dataset
includes both the full dataset used for the analysis
(PositiveInteractionsF.csv), a small subset of the data used to evaluate
the stress gradient hypothesis (PositiveInteractionsStress.csv), and
geographical information on study locations
(PositiveInteractionsLocs.csv).
