Fox Foto Friday - This Is Island Fox Science

Fresh from the fox swabs...This past week, Friends of the Island Fox had the opportunity to spend some time in the field with the biologists of the Catalina Island Conservancy during their final days this season counting and providing island foxes with health checks.

During health checks, samples, like the one shown above, were taken. (how are island foxes swabbed?)

Soon these swabs will be boxed up and sent across the country to enrich the data set of Dr. Alexandra De Candia. During FIF's first virtual "Date with a Fox," Dr. Allie shared her work on the island fox microbiome and its importance for fox health and immunity.

Dr. Allie explains that Catalina Island biologists "have been collecting swabs since 2017, so we are building a really nice longitudinal dataset. 2020–2021 samples will help that dataset grow. This will allow us to look at changes in fox microbiomes through time and (once we have enough repeat individuals sampled) see how treatment or past history of mite infection alters microbiomes in the short- and long-term."

If you missed the virtual event you can watch the video here.

More on the connection between microbiome and fox health on Catalina Island.

Not only were the CIC biologists taking these samples to enrich the microbiome data set, they were also putting radio collars, funded by you, on island foxes.

What smells like an island fox? Came from an island fox? But is contained on the tip of a cotton swab? A sample of island fox microbiome.

Friends of the Island Fox recently heard from FIF 2020 Research Grant recipient, Alexandria DeCandia, Ph.D.

DeCandia wrote "I wanted to let you know that microbiome samples from all six islands have arrived on the east coast :)" Swabs taken from island foxes during health checks have been transferred to a lab in Washington D.C. She added, "I'm very much looking forward to the next steps of this research!"

FIF's Research Grant is funding the DNA analysis of the swabs to get a picture of the biodiversity of microbes living on and in island foxes.

What Is She Looking For?

DeCandia's research is cutting edge science. Her early analysis of Catalina Island foxes led to some important findings on the possible relationships between bacteria in island fox ear canals and a tendency toward extreme immune system response to ear mites. This next stage of research builds on that work.

Maintaining healthy island foxes across the islands requires greater in depth understanding of their health, diet, position in the ecosystem, and interactions with other species, including humans. 

Friends of the Island Fox invests in research to invest in the island fox's future. Applications for the FIF 2021 Research Grant will be available April 15, 2021.
