Male Antelope Lie To Get Sex

Home » All Things SimBio » Male Antelope Lie To Get Sex

May 25, 2010 //  by John Herron

Earlier I mentioned examples of critters that lie to get what they want. Last week in American Naturalist Jakob Bro-Jørgensen and Wiline M. Pangle reported a new—and at least half interesting—example.

The critter in question is the topi, an African antelope.

There are two relevant pieces of topi natural history. First, during the rut, male topi defend territories. When a female is in heat (for one day only), she visits numerous territories and mates with many of their owners. Second, when topi discover they are being stalked by a lion or other predator, they stare at the stalker and snort. Topi can escape most predators so long as they get a head start; the alarm snort says “I’ve spotted you already, so don’t bother chasing me.”

So now imagine a female topi in heat visits a male’s territory, gets what she came for, then heads for the border while our boy is still feeling amorous. He wants her to stay just a little bit longer. What can do to persuade her?

He can lie.

He stares off in the direction the female is walking and snorts. When she stops and looks around, he asks for one more dance.

Believe it or not, sometimes it works.

For more details, see Bro-Jørgensen and Pangle’s paper.

The topi photo is by Simyre, who has released it into the public domain.

Testimonials

“[SimBio’s modules] provide a powerful environment for hands-on, active learning in Ecology and Evolution. The depth, design, and pedagogical effectiveness of these packages is unequaled. They have greatly enriched student interest and understanding in all of my courses, from Introductory Biology to Advanced Population Biology”

— Dr. Brad Lister
Rensselaer Polytechnic Institute

“The lab simulations have been very helpful to reinforce the lecture content and encourage students to use critical thinking skills to solve problems.”

— Patti Fallest-Strobl
Neumann University

“I was amazed how quickly and effortlessly the simulation taught them a dynamic system.”

— Paula Philbrick
University of Connecticut

“The students like [it] so much that they are working ahead of what I have assigned. They just think it’s fun. And from the quiz results I have so far, they’re really getting it. You guys are geniuses.”

— Paulette Bierzychudek
Lewis & Clark College

“Since we began using Simbio’s Ecology chapters our students consistently come to class better prepared. This is a key to the success of our hybrid flipped classroom approach.”

— Dr. Peter Curtis
Ohio State University

“That was the most fun I’ve had teaching ecology and, I would venture to guess, the most fun my students have had taking ecology from me.”

— Matt Orr
Oregon State University, Cascades

“Our students are more prepared and our class discussions are more sophisticated because SimUText is such a great out of class “instructor”. Since our students have SimUText preparation we can spend class time applying concepts and evaluating new information.”

— Emily Bernhardt
Duke University

“I LOVE that every lab is based on a real study. I LOVE that all of the labs offer an open-ended inquiry. I LOVE that the labs gradually teach the concepts and build up a repertoire of data collection techniques. Thank you, for creating them.”

— Jeanette Williams
Community College of Vermont

“I just wanted to say how great simutext has been. I could have memorized facts about the electron transport chain and passed the test, but would not have had any solid concept of what was happening inside. I hope that we continue to use it often even when things return to normal.”

— Student
Rochester Community and Technical College

“Congratulations for developing such a high quality chapter. I was very impressed by its comprehensiveness, accuracy, and thoughtful design. It really is superb.”

— Richard Boone
Humboldt State University

“I recommend your modules to anyone I can, because of all the online materials I’ve found, SimBio is really the best in content and best managed. I am definitely a SimBio fan!”

— Valerie Anderson
Marymount California University
