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! besjournals.onlinelibrary.wiley.com/doi/10.1111/13…
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-events/pr…
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. onlinelibrary.wiley.com/doi/10.1111/el…
PHD STUDENT WANTED! ...to work in my project “How does animal-mediated seed dispersal affect range shifts of European beech in the Swiss Alps?” All details provided in the link. *funded by National Science Centre in Poland (Sonata) ibs.bialowieza.pl/ogloszenia/nab…
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.
I'm recruiting a PhD student and at least one masters student starting fall 2025. Please get in touch if you are interested! #Ecology
Check out the new paper in Mycologia by Alassane Sow et al. - a collaboration by our lab and Greg Bonito's lab at MSU describing two edible North American truffles. @BenLemmond @JudVanWyk : tandfonline.com/doi/full/10.10…

Ectomycorrhizal fungi in the genus Tuber form hypogeous fruiting bodies called truffles. Many Tuber species are highly prized due to their edible and aromatic ascomata. Historically, there has been...
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.44…)!
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/10.100…

I'm awaiting funding decisions but anticipate recruiting a PhD student for fall 2025 If ur @ #TWS2024, have interests & skills that align w/our lab, & want 2 talk, pls get in touch or stop by the poster session where I'll present on coyote work done w/@RolandKays & #SnapshotUSA
Europe is facing a seed dispersal “crisis,” due to extinction threats and population changes among the animals that do the seed dispersing, according to a new study in Science. bit.ly/4dKyW0s
