Out in @AnimalEcology, we investigate the influence of masting on timing of reproduction in small mammals using a 12-year dataset. Seed availability alters probability of reproduction for both sexes and can change timing of reproduction by over 2 months!

Truffles and carnivores made the news. Our Ecology Letters paper was picked up by the @TheEconomist last week: economist.com/science-and-te…

Research shows that carnivores play an important role in ecosystem function by providing a largely overlooked mechanism for long-distance dispersal of beneficial mycorrhizal fungi. twin-cities.umn.edu/news-eve…

Out in @Ecology_Letters! We assessed the effectiveness of #carnivores as secondary dispersers of mycorrhizal #fungi. Larger carnivores deposited fewer spores but moved them farther, creating a continuum between the quantity & quality aspects of dispersal.

Outer space is harsh. Extreme temperatures and radiation can break down most materials, but a study on the International Space Station finds a biological molecule that holds its own: melanin derived from fungus. In PNAS: ow.ly/QvbA50VLAZb

Looking for wild owl scat and pellets. We are investigating secondary spore dispersal in owls and have some cool feeding trial results but would like to demonstrate that this is occurring in the wild. Looking for forest-dwelling species. Please reach out if want to collaborate.

Asked if this was an NMDS ordination. Turns out it’s “small mammal poops”. Looks like we have an #ecologist in the making; although I wonder what his teachers think when he explains his drawings.

Extremely excited to say that the final chapter of my MS thesis was just published open access in Ecology @ESA_org (doi.org/10.1002/ecy.4454)!

Autum is coming.
It's time to start tracking the fate of seeds dispersed by rodents. This season - invasive red oak (Quercus rubra) acorns.
I used seed tagging in several of my previous studies, e.g. link.springer.com/article/10…

I've found 9 AMF spore morphotypes in the scat of mammals and I'm wondering if anyone might be able to help me get to species, genus, or family level. Given that animals are eating them, many are likely sporocarpic species.

Last one. This one is very large and appears to be more melonized than the others. I also detected it less often.
