Abstract The development of encompassing general models of ecology is precluded by underrepresentation of certain taxa and systems. Models predicting context‐dependent outcomes of biotic interactions have been tested using plants and bacteria, but their applicability to higher taxa is largely unknown. We examined context dependency in a reproductive mutualism between two stream fish species: mound nest‐building bluehead chub Nocomis leptocephalus and mountain redbelly dace Chrosomus oreas…

Mutualism or parasitism: Partner abundance affects host fitness in a fish reproductive interaction
TLDR
Results show that outcomes of biotic interactions in freshwater systems are context‐dependent, and that partner abundance can be a key source of context‐dependency in nest associations, and encourage future studies on freshwater mutualisms, which are thus far largely overlooked.
Positive co‐occurrence between feeding‐associative savannah fishes depends on species and habitat
TLDR
It is indicated that biotic interactions between species of freshwater fish can be evident beyond the microhabitat scale to positively influence species co‐occurrence and adds to evidence from other groups of freshwater organisms indicating the importance ofBiotic interactions in facilitating species co-occurrence.
Positive Interactions in Freshwater Systems
Positive interspecific interactions (mutualism, commensalism, and facilitation) are ubiquitous in nature, but understudied in freshwater ecosystems. This review assesses the state-of-the-knowledge of
Strong effects of a mutualism on freshwater community structure.
TLDR
The results are the first to demonstrate strong effects of a mutualism on freshwater communities and both members of this mutualism are found throughout the northern hemisphere, so similar impacts may occur in many other waterways.
Positive biotic interactions in freshwaters: A review and research directive
Positive interspecific interactions such as mutualism, commensalism, and facilitation are globally ubiquitous. Although research on positive interactions in terrestrial and marine systems has
Disentangling Reproductive Interactions among Communal Spawning Minnows Using Reproductive Condition and Visual Observations
TLDR
Paired together, the GSI and behavioral observations suggest stoneroller does not require chub nests for spawning and may exploit nests as a trophic resource if no eggs are contributed, demonstrating the close reproductive link between some symbiotic species and their hosts that is required for successful reproduction.
Diverse reproductive patterns of Bluehead Chub (Nocomis leptocephalus) and their relationships with nest size and interactions with an associate, Yellowfin Shiner (Notropis lutipinnis)
TLDR
It is suggested that complex mechanisms mediate host nest size and interactions with nest associates, and individual variation likely shapes dynamics of the mutualistic reproductive interaction.
DNA Barcoding Elucidates Cyprinid Reproductive Interactions in a Southwest Virginia Stream
TLDR
This work used visual surveys and DNA barcoding to identify cyprinids that were associated with the nests of spawning chub in Catawba Creek, a small tributary of the James River in southwestern Virginia.
Muddying the waters: investigating the generality of silt-resistance in mound-building Nocomis spp. using hornyhead chub (Nocomis biguttatus) and redspot chub (Nocomis asper)
TLDR
The results suggested that neither species were silt-resistant, potentially meaning their ability to function as keystone engineers could be compromised in streams with excess sedimentation, and the implementation of land management practices that reduce soil erosion may be necessary to recover populations of these Nocomis spp.
A case for conserving common species
TLDR
This is the story of building my niche as an ecosystem engineer, and of recognizing the ecological role of species the authors take for granted—and why they should fund research on common species that may sustain the rare ones.

Quantitative synthesis of context dependency in ant-plant protection mutualisms.
TLDR
A meta-analysis of ant-plant protection mutualisms to examine the generality of context-dependent effects of ants on herbivory and plant performance (growth, reproduction) indicates that context dependency may not be a general feature of mutualistic interactions.
Lotic cyprinid communities can be structured as nest webs and predicted by the stress-gradient hypothesis.
TLDR
It is demonstrated that nest webs can be useful in a variety of systems and that SEM can be a quantitative extension of this framework, and the SGH can be used to understand positive interactions in animal communities and can be extended to predict proportional representation of facilitating and beneficiary species in communities.
Biotic interactions in freshwater benthic habitats
TLDR
Benthologists are urged to explore how populations evolve in response to biotic interactions embedded in benthic communities and to assess how these responses might redefine trophic and community structure and their emergent properties.
Evidence of mutual benefits of nest association among freshwater cyprinids and implications for conservation
TLDR
Nest association mechanisms were explored using a multiple working hypotheses framework on fish assemblage data from 25 reaches in three tributaries of the New River, Virginia, USA and chubs and associates appear to receive a net benefit from the association, suggesting a mutualistic relationship.
The mutualism-parasitism continuum in ectomycorrhizas: a quantitative assessment using meta-analysis.
TLDR
The results indicate that the variation in ectomycorrhizal fungi perceived by the host may be of a discrete (presence/absence) rather than continuous nature (variation in identity or abundance of ectomy corollary fungi).
Diversity in interspecific interactions between a nest-associating species, Pungtungia herzi, and multiple host species
TLDR
Compared with another known host, the freshwater perch Coreoperca kawamebari, the observed differences in the impact of nest association to the associate species likely correspond to Differences in the spatial reproductive resources used by the respective hosts.
Biotic interactions and habitat drive positive co‐occurrence between facilitating and beneficiary stream fishes
TLDR
This study provides some of the first large-scale quantitative evidence of positive co-occurrence among vertebrates, and demonstrates the importance of abiotic context for mediating interspecific interactions.
Impacts of insect herbivory on cactus population dynamics: experimental demography across an environmental gradient
TLDR
Tree cholla density increased significantly with elevation, while abundance of and damage by a suite of native, cactus-feeding insects decreased, prompting the hypothesis that systematic spatial variation in chronic insect herbivory affects patterns of plant distribution.
How context dependent are species interactions?
TLDR
Meta-analysis is used to quantify variation in species interaction outcomes (competition, mutualism, or predation) for 247 published articles and urges that studying context dependency per se can provide a general method for describing patterns of variation in nature.
The Strength of Nocomis Nest Association Contributes to Patterns of Rarity and Commonness among New River, Virginia Cyprinids
TLDR
Nest association strength is related to rarity; this potentially crucial aspect of conservation has been previously overlooked and should be pursued through protection of their host and, consequently, the mutualism they have evolved to exploit.
