Sometimes a single food source suddenly becomes hugely abundant, and animals that normally eat other things switch to feast on it. These food pulses can set off chain reactions through a food web.

What they work on

  1. Test whether ants opportunistically shift their foraging to periodical cicadas during the spring emergence and the later summer hatch, using direct observations, nutrient baiting and pitfall trapping.
  2. Measure whether cicada-driven foraging shifts change the seed dispersal, scavenging and aphid protection that ants provide, using ant exclusion experiments in forest plots.
  3. Use stable isotope analysis to test whether ants that start at different trophic positions converge on a common diet in cicada emergence years compared with non-emergence years.
  4. Examine how cicada pulses change the strength of competition among ant species and their mutualisms, through comparisons within and between years.

More about the research

Every 13 or 17 years, billions of periodical cicadas emerge at once in the eastern U.S. Their emergence is one of the largest insect food pulses on Earth. This collaborative project asks how cicada pulses affect ants, which are among the most abundant animals on the planet. It also asks whether ants keep doing their usual ecological jobs when they switch diets.

Why it matters

Ants disperse seeds, scavenge, and tend insects in ways that matter for forestry and agriculture. Learning how a sudden food surplus changes these services could help predict how forest ecosystems respond to disruptions. It also adds data to the very limited body of work on how food pulses affect land invertebrates.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
