Estimating the effects of non‐native species on nutrient recycling using species‐specific and general allometric models

Abstract: Non‐native species are now common in community assemblages, but the influence of multiple introductions on ecosystem functioning remains poorly understood. In highly invaded systems, one promising approach is to use functional traits to scale measured individuals’ effects on ecosystem function up to the community level. This approach assumes that functional traits provide a common currency among species to relate individuals to ecosystem functioning. The goals of this study were to (i) test whether the relatio… Show more

“…We found that family was overall best supported as the taxonomic level at which body nutrient content is conserved, although genus was a better predictor of some nutrient ratios. This finding is consistent with past studies testing EST [10][11][12] and inconsistent with others. For example, Gonzalez et al 18 found that the level of taxonomy that best predict body nutrient content was dependent on the element in question, and Wiesenborn 57 found P in invertebrates was best predicted by order.…”

“…Because they are often the dominant pool of biomass (particularly in many aquatic systems), animals can also represent an important reservoir of nutrients stored in their tissue 9 . While previous work has shown the supply of nutrients from animals via excretion is highly predictable based on rules of allometry [10][11][12] , no universal factor has been found to broadly predict the amount of nutrients stored in the body tissue of organisms [13][14][15][16][17][18] .…”

“…Establishing links between traits and their functions to ecosystems is a challenging endeavor (Bellwood et al, 2019), although some studies have highlighted the importance of intraspecific trait variability to aquatic ecosystem processes (Raffard et al, 2017). For example, body size is perhaps the most commonly measured individual trait used to predict fish contributions to ecosystem processes (Villéger et al, 2017), often in the form of nutrient transport and recycling (Fritschie & Olden, 2018). However, individuals of the same body size in two species of estuarine snappers ( Lutjanus griseus and L. cyanopterus ) demonstrated a twofold difference in estimated ecosystem function when intraspecific variability in behavioral traits was considered (Allgeier et al, 2020).…”

“…The following hypotheses were tested: (H 1 ) decapod presence would result in increased consumption of resources, especially by invasive species (Haddaway et al., ; Rosewarne et al., ), particularly slow‐moving species such as gastropods and other invertebrates, leading to (H 2 ) reduced grazing pressure and an increase in primary and gross primary production. It was also expected that (H 3 ) decomposition rates would be maintained or even enhanced in invasive species treatments, despite depletion of shredding invertebrates, due to high omnivory amongst decapods (Doherty‐Bone et al., ; Dunoyer et al., ; Usio, ); and (H 4 ) invasive alien decapods would alter water quality through changes to dissolved nutrients from excretal products (Doherty‐Bone et al., ; Evans‐White & Lamberti, ; Fritschie & Olden, ; Usio, Suzuku, Konishi, & Nakano, ), increased turbidity from bioturbation (Harvey et al., ) and particulate carbon from detritivory (Doherty‐Bone et al., ).…”
