Daniel Gruner - Biodiversity and Community Ecology

I am a community ecologist with empirical projects on tropical islands, and coastal wetlands, montane grasslands, and local agricultural systems, and I use a variety of analytical tools for synthetic reviews and statistical modeling. Generally, our lab investigates species interactions in food webs, the maintenance of biodiversity in ecological communities, and community feedbacks with ecosystem function. I research these topics primarily using arthropods in terrestrial ecosystems, but I work in soils and in treetops, with organisms from nematodes to birds to herbaceous plants, and in both temperate and tropical regions. I believe it is important to apply basic science to address environmental challenges, particularly with biodiversity conservation, biological invasions, and climate change.

Congratulations to Lily Durkee! In the Montgomery-Blair High School Senior Research Project Convention, she received two prizes for her research in the lab: first place in General Biology, and the top overall prize for biological sciences, the Dr. Vaccaro Research Scholarship! Lily will enroll at UMD in the fall on a FULL RIDE with a Banneker/Key Scholarship! (Apr 2014)

Elske's Masters thesis research is now published in Biological Conservation, here! (April 2014)

Cora Johnston presented her results from crab larvae and settlement surveys at the Benthics meeting in Jacksonville. (March 2014)

Two papers from the Nutrient Network collaboration appeared together in an issue of Nature! Meanwhile both are online, here and here. See also the news writeup prepared by Heather Dewar for the College of Computer, Mathematical, and Natural Sciences. In summary, this work demonstrates that eutrophication destabilizes grassland plant diversity, but herbivores can rescue diversity in many cases by opening up the canopy allowing light to penetrate.

"If you cultivate a healthy poverty and simplicity, so that finding a penny will literally make your day, then, since the world is in fact planted with pennies, you have with your poverty bought a lifetime of days."
