Welcome to postdocs Laura and Patrick!

Standard

We’re a little late in getting Patrick’s start announced, and very late for Laura’s, but on the principle of better late than never:

Dr. Laura Lopez started as a postdoc in August (I told you we’re late in getting this announced!) Laura is earned her PhD in 2017 from the University of Wollongong in Australia, where she worked with Andy Davis and Marian Wong. She then did an Australia Awards Endeavour postdoc at UC Davis, where she worked with Andy Sih. Laura is interested in behavioral ecology and natural enemy ecology, as well as the conservation of freshwater ecosystems. She’s working on projects at the interface of behavioral ecology, disease ecology, and predation.

Dr. Patrick Clay started as a postdoc in April (phew, we’re not so late in announcing his start!) Patrick just earned his PhD from Rice University, where he worked with Volker Rudolf (but also collaborated with the Duffy Lab!) Patrick is a disease ecologist who is especially interested in co-infections and in how processes that occur at the within host level scale to populations and communities.

We’re very excited to have both of them in the lab!

Daphnia go to Washington to argue for the importance of basic scientific research!

Standard

Meghan visited Washington, DC for the Coalition for National Science Funding exhibition, where she talked about the importance of basic scientific research. She got a chance to introduce lots of folks, including Congressman Jack Bergman, to Daphnia!

Meghan’s day was filled with meetings with staffers on the Hill, followed by her poster presentation at the CNSF exhibition. More information on the trip can be found here.

Duffy Lab research featured by PBS NewsHour!

Standard

PBS NewsHour recently featured Daphnia! Their piece includes both video and a write up, which begins:

From a human perspective, the clear, calm waters of Michigan’s lakes — surrounded by trees, filled with fish, reflecting the sky — could hardly be more peaceful.

For the tiny critters below the surface, it’s a life-or-death battlefield. “Water fleas” dart from place to place, collecting food, dodging predators and fighting diseases.

We’re really excited about how it all turned out. Click through to read the whole article! You can watch the video either in that article or here:

Two recent papers on interactions between parasites!

Standard

Patrick Clay, a visiting grad student from Rice who will return as a postdoc this spring, is lead author on two papers exploring how interactions between parasites influence ecological dynamics. Most studies focus on just a single parasite infecting a host, but the norm in nature is that there are multiple parasites circulating in a population at a time. (If you doubt this, just visit the nearest daycare.)

In a Clay et al. paper that just appeared in The American Naturalist, we show that the order in which two parasites arrive in a single infected host influences the effects they have on each other and on the host. That, in turn, influences how likely it is that the two parasites will coexist. This paper uses data collected by former Duffy Lab undergrad Kailash Dhir.

The second paper (in press at Oikos) is a theory paper that shows that parasites that harm each other within individual hosts can actually facilitate each other’s spread at the population scale. These results suggest that within‐host priority effects can change host population‐scale infection patterns in systematic (and initially counterintuitive) ways, and that taking them into account may improve disease forecasting in coinfected populations.

Clara to teach at UMBS this spring!

Standard

Clara Shaw will be teaching the Spring Term section of General Ecology at the University of Michigan Biological Station this May-June. Clara received a Master’s in Education from the University of Mississippi before joining our EEB PhD program, so this will be a great way to combine her love of ecology and her love of teaching.

More info can be found here! And congrats, Clara!
