Density- and trait-mediated effects of a parasite and a predator in a tri-trophic food web
TLDR
A mixture of density-mediated and trait-mediated indirect effects of parasitism on non-host species creates rich and complex possibilities for effects of parasites in food webs that should be included in assessments of possible impacts of parasite eradication or introduction. Expand
Phenotypic plasticity, intraguild predation and anti‐cannibal defences in an enigmatic polymorphic ciliate
TLDR
Morph dynamics are consistent with the hypothesis that tailed microstomes function as an inducible defence against cannibalism, and the simultaneous induction of tailedmicrostomes and macrostomes suggests that both morphs comprise a coordinated adaptive response to the presence of intraguild prey. Expand
Spatial and temporal dynamics of a freshwater eukaryotic plankton community revealed via 18S rRNA gene metabarcoding
TLDR
Comparisons of sequence-based population survey data to conventional-based data revealed similar trends for taxa that were ranked among the most abundant in both approaches, although some groups were missing in each data set. Expand
Evaluating putative ecological drivers of microcystin spatiotemporal dynamics using metabarcoding and environmental data.
TLDR
Random forest regression analyses with 16S and 18S rRNA gene sequencing data and environmental data revealed that factors that were the most important in predicting MC-LR were also the mostimportant in predicting Microcystis population dynamics, and how these results relate to prevailing ecological hypotheses regarding the function of microcystin is discussed.

Trait-mediated apparent competition in an intraguild predator–prey system
TLDR
This work shows that trait-mediated apparent competition can arise from inducible offenses and show how it operates using experiments involving three ciliates, and indicates that developmental expansions such as those underlying the interactions observed in this study are not limited to cilia, but occur among many diverse taxa and may have a surprising degree of influence over the structure and dynamics of food webs.

High-throughput environmental DNA analysis informs a biological assessment of an urban stream
TLDR
It is suggested that even a simple seston eDNA filtering protocol can provide biodiversity information of value to stream bioassessment programs, and the approach bears further investigation as a potentially useful rapid assessment protocol to supplement more intensive field sampling efforts. Expand
Bringing Community Ecology to Bear on the Issue of Antimicrobial Resistance
TLDR
This review elucidate how species interactions promote and impede the establishment, maintenance, and spread of ARGs and indicates how management initiatives might benefit from leveraging the principles and tools of community ecology to better understand and manipulate the processes underlying AMR. Expand
Dynamics and adaptive significance of the inducible trophic polymorphism of tetrahymena vorax
TLDR
This dissertation provides unique insights into the link between ITPs and related phenomena – such as cannibalism, intraguild predation, omnivory, and expanded diet breadth – and open new avenues of inquiry regarding the importance of the genetic and functional diversity of natural communities. Expand
Metabarcoding quantifies differences in accumulation of ballast water borne biodiversity among three port systems in the United States.
TLDR
High throughput sequence metabarcoding of the 18S small subunit rRNA is used to test for and quantify differences in the accumulation of BW-borne biodiversity among three distinct recipient port systems in the United States, suggesting that saturation of introduced zooplankton diversity may be achieved quickly and molecular diversity may not decline significantly with BW age. Expand
Acquisition of Adaptive Traits via Interspecific Association: Ecological Consequences and Applications
TLDR
The mechanisms of this exogenous trait acquisition are reviewed and some of their repercussions and usefulness for natural resource management, industry, and human health are highlighted. Expand
