Consumer-mediated recycling and cascading trophic interactions.

Cascading trophic interactions mediated by consumers are complex phenomena, which encompass many direct and indirect effects. Nonetheless, most experiments and theory on the topic focus uniquely on the indirect, positive effects of predators on producers via regulation of herbivores. Empirical research in aquatic ecosystems, however, demonstrate that the indirect, positive effects of consumer-m...

The Lost Buckyballs

A 15-year-old female with no past medical history presented 3 hours after ingesting 2 Buckyballs she had been using to create a mock tongue piercing. Buckyballs are 5-mm magnets made of neodymium, which is 5 times more powerful than a regular magnet. They are used as educational toys and as an artistic medium. Buckyball stopped production in 2012 after many cases of ingestion and a United State...

Importance of species interactions to community heritability: a genetic basis to trophic-level interactions.

Recent community genetics studies have shown that specific genotypes of a host plant support distinct arthropod communities. Building upon these findings, we examined the hypothesis that a trophic community consisting of cottonwood trees, a galling herbivore and avian predators could also be related to the genetics of the host tree. We found genetic correlations among phytochemistry of individu...
