  • Reviews for Richard Conniff’s Books

    Every Creeping Thing: True Tales of Faintly Repulsive Wildlife: “Conniff is a splendid writer–fresh, clear, uncondescending, and with never a false step; one can’t resist quoting him.” (NY Times Book Review)

    The Species Seekers:  Heroes, Fools, and the Mad Pursuit of Life on Earth by Richard Conniff is “a swashbuckling romp” that “brilliantly evokes that just-before Darwin era” (BBC Focus) and “an enduring story bursting at the seams with intriguing, fantastical and disturbing anecdotes” (New Scientist). “This beautifully written book has the verve of an adventure story” (Wall St. Journal)

    Swimming with Piranhas at Feeding Time by Richard Conniff  is “Hilariously informative…This book will remind you why you always wanted to be a naturalist.” (Outside magazine) “Field naturalist Conniff’s animal adventures … are so amusing and full color that they burst right off the page …  a quick and intensely pleasurable read.” (Seed magazine) “Conniff’s poetic accounts of giraffes drifting past like sail boats, and his feeble attempts to educate Vervet monkeys on the wonders of tissue paper will leave your heart and sides aching.  An excellent read.” (BBC Focus magazine)

Nose-Picking For New Species

Posted by Richard Conniff on October 17, 2013

For all of you who have been covertly digging for hidden treasure up your nose, here’s proof that it really can happen.  I came across this little gem on the Verge:

After returning from an African research expedition, pathobiology professor Tony Goldberg found an unexpected stowaway: a tick hiding up his right nostril. “When you first realize you have a tick up your nose, it takes a lot of willpower not to claw your face off,” Goldberg, a University of Wisconsin–Madison researcher, says in a statement.

But Goldberg managed to retrieve the tick from his nostril and send it off for analysis, leading him to not just discover a potentially new species of tick, but what could also be a new explanation for how diseases spread between chimps and humans.

Though DNA analysis could only confirm the tick’s genus — and not whether it was a new species — because it wasn’t fully developed, its presence made Goldberg curious about why it was hiding up there in the first place.

[Technical note:  That “wasn’t fully developed” makes no sense.  What Goldberg’s published account actually says is that the researchers couldn’t find a match on GenBank for the mitochondrial DNA they sequenced.]

Goldberg and other researchers began studying high-resolution photographs of chimps, and they noticed that 20 percent of the chimps had ticks hiding up their nostrils. And that number could be even higher: the photos were far from perfect for studying tick infestations, as they’d originally been  taken to examine chimps’ teeth. The researchers speculate that additional ticks may simply have been out of sight in the photographs.

The findings were published on September 30th in The American Journal of Tropical Medicine and Hygiene, and focus on chimps and ticks in the Kibale National Park in Uganda. In their paper, Goldberg and others suggest that hiding up nostrils may be an adaptation that these ticks have picked up in order to remain undetected. Chimps frequently groom each other, and by hiding up a nostril, the ticks may be able to feed safely.

But many of these ticks need to feed on three different hosts before they can complete their life cycle, and because they’ve been found to carry diseases, the researchers suggest these undetected ticks may enable pathogens to spread.

“This could be an underappreciated, indirect, and somewhat weird way in which people and chimps share pathogens,” says Goldberg. The researchers note this could allow diseases to spread between animals as well.

The researchers haven’t been able to capture any additional ticks, and though they might like to, examining chimps directly isn’t an option they’re currently considering. “It’s not really practical or safe to pick ticks out of chimps’ noses,” Goldberg says in a statement. “The chimps of Kibale are very well habituated to humans, but they would still object vigorously.”

The researchers admit that ticks making their way into a human nostril is a rare occurrence, but nonetheless, they suggest there’s some risk of international travelers unknowingly helping the ticks set up a population in a foreign country.

Here’s another account from the University of Wisconsin.  The whole thing makes me wonder if I flushed my chance at discovery down the toilet that time I came back from the Panama rain forest with ticks between my toes.  And what about those land leeches on Madagascar?

For all the rest of you nose-pickers out there, well, happy hunting.
