Cassie Stoddard wins Packard Fellowship for early-career scientists
Oct. 16, 2018

Mary Caswell "Cassie" Stoddard is one of 18 researchers to receive a Packard Fellowship for Science and Engineering from The David and Lucile Packard Foundation, targeted to innovative, early-career scientists and engineers. Stoddard studies the extraordinary diversity of signals and traits in nature. Her lab investigates the evolution of…

Ant-y social: Successful ant colonies hint at how societies evolve
Oct. 3, 2018

Graduate student Chris Tokita in the Tarnita Lab worked closely with researchers from Rockefeller University to investigate ant colonies looking at the relationship between group size and social behaviors. They found that simply increasing group size, even if it doesn’t lead to division of labor, can benefit members of the group. “Our findings…

Bridgett vonHoldt: A genetic test helps determine a dog's social tendencies
Sept. 24, 2018

Pet lovers seeking a better understanding of their four-footed friends might benefit from a new genetic test for sociability in dogs. While studying the genomes of canines Bridgett vonHoldy, assistant professor of ecology and evolutionary biology, and her colleagues discovered genes in domestic dogs that are similar to those linked to hyper…

Cole Morokhovich studies color vision of hummingbirds in the Colorado Rockies
Sept. 10, 2018

I spent my summer as a research assistant for Professor Stoddard in the Stoddard lab researching hummingbird color vision at the Rocky Mountain Biological Laboratory in the Colorado Rockies. Part of my responsibilities included taking spectrophotometer measurements of flowers frequently visited by hummingbirds, as well as filming the…

Jack Corso looks at the spatial ecology of the fringing, barrier and outer slope reef ecosystems
Aug. 2, 2018

Undergraduate Jack Corso '19 works in Steve Pacala's lab at Princeton. This summer he spent his time in La Jolla, California learning the intricacies of the coral reef photomosaic methodology. Corso also traveled to the French Polynesian island of Moorea, located in the Society Island Archipelago. While on Moorea he stayed and worked out of the…

Parasitization of plains zebras and the endangered Grevy’s zebras
Aug. 2, 2018

Undergraduate Lindsay Martinez spent her summer working on her senior thesis project at the Mpala Research Centre in Kenya. She is looking at the parasitization of plains zebras and the endangered Grevy’s zebras by a gastrointestinal parasite called a strongyle. To study the intensity of infection with strongyles she opportunistically collected…

Understanding the ecosystem dynamics of the shrubland biomes
Aug. 2, 2018

Graduate student Ciro Cabal is trying to understand the ecosystem dynamics of the shrubland biomes, and concretely some endogenous and exogenous causes of its existence and physiognomy. Among the endogenous causes, I am interested in disentangling the role of the optimization of individual reproduction allocation in woody plants, developing…

What can Rocky Mountain wildflowers tell us about pathogen evolution?
Aug. 2, 2018

PhD student Ian Miller spent part of his summer outside of Crested Butte, Colorado, studying wild flax and its fungal rust pathogen. The flax-rust system is the classic "gene-for-gene" system, in which pathogens evolve "virulence alleles" that allow them to infect hosts that have evolved "resistance alleles." The ability to infect hosts is…

Members of EEB call for an integrative molecular approach to wildlife disease studies
Aug. 1, 2018

An essay by Alexandra DeCandia, Andy Dobson, and Bridgett vonHoldt argues for more widespread adoption of diverse molecular methods – examining host and parasite genetics, epigenetics, and microbiome – in studies of wildlife disease. They review insights gained from these analyses in recent years (predominantly focusing on chytridiomycosis in…
