Organization:March Mammal Madness

The 2016 Logo for Mammal March Madness designed by Cyn Rudzis.

March Mammal Madness is an alternate March Madness tournament focusing on simulated combat between mammals. Katie Hinde created March Mammal Madness, using a 64 animal bracket, with the goal of using biological research to create (simulated) battles.

Katie Hinde, originally an assistant professor in the Department of Human Evolutionary Biology at Harvard University and currently an associate professor in the School of Human Evolution and Social Change at Arizona State University, later brought in three other educators to help her organize the event. This includes assistant professor at Boston University School of Medicine Kristi Lewton, lecturer at Columbia University Joshua Drew, and assistant professor at Dominican University Christopher Anderson. Along with these educators, the artist Charon Henning provides artwork of the various mammal competitors throughout the whole tournament. Together, they heavily research all of the combatants, using what they learn to provide an entertaining and informative experience.

In 2017, more educators were added on to the March Mammal Madness team to help with the competition. This includes Ph.D. student at the University of Notre Dame Mauna Dasari, postdoctoral fellow at the University of Notre Dame Marc Kissel, post-doctoral researcher and instructor at the University of Utah Patrice Kurnath Connors, visiting assisting professor for the department of biological sciences at Southern Illinois University Danielle Lee, and associate professor and curator of mammals at the Texas A&M University Jessica Light. Two other educators were added to tweet about genetics, genomics, and the phylogeny of the various mammals participating. This includes Anne Stone of the School of Human Evolution and Social Change, and Melissa Wilson Sayres from the School of Life Sciences at Arizona State University.

Bracket

The bracket itself is modeled after the NCAA championship, including an Elite Eight and a Final Four. The bracket is divided into four divisions, which change yearly. The 64 animals are chosen and put into the various divisions based on their characteristics. In the 2015 bracket, the chosen divisions were Mighty Mini Mammals, Mythical Mammals, Critically Endangered Mammals, and Sexy Beasts. Mammals such as the dwarf mongoose and the Java mouse-deer were chosen for the Mighty Mini Mammals, while legendary beasts such as Ratatoskr and the Yeti battled it out in the Mythical Mammals. The mammals compete against others in their division, eventually working their way down to the Final Four (one from each division), and finally the championship.

Battles

The battles are decided by a mix of scientific research, and an element of chance. Katie Hinde and the March Mammal Madness organizing team do in-depth research on the mammal contestants. Temperament, diet, social behavior, environment, size, and fight style are just a few of the factors that are taken into consideration. After these factors are weighed against each other, Hinde and the rest determine probability of one animal defeating another. This is how they develop the seed, or rank, of each mammal. Then a 100 sided die is rolled with a determined percentage numbers attributed to each animal. This adds an element of chance, since out in nature nothing is 100% guaranteed. Additionally, the environment in which the encounter takes place can be a major factor in the outcome. For the first few rounds, each fight takes place in the environment of the higher seeded animal. After the Sweet Sixteen, it is chosen at random and announced immediately prior to the encounter.

Combining research with an element of chance has led to some major upsets, just like with any sports bracket. In round one of the 2015 Mighty Mini Mammal division, the 14th-seeded numbat defeated the 3rd-seed quokka. The research is then used to create a narrative to explain the loss. The narratives can range from a serious battle, to humorous happenstance. In 2014, research showed the pangolin to be the most trafficked animal on the planet. Before the match even began, the pangolin was captured by poachers and shipped away, forfeiting the fight. Each round has a scheduled day and time, found on Katie Hinde's blog, Mammals Suck... Milk!.

Instead of just announcing the winners, the written narratives are live-tweeted like the match was happening that very moment. Fans can follow along and tweet back using the designated March Mammal Madness hashtag, creating a fun and exciting atmosphere where people can learn about the animals they support.

In 2017, the wildcard match was performed as a live-action movie to celebrate the 5th anniversary of the tournament. The wildcard match was also done with four mammal competitors instead of the usual two. Members of the March Mammal Madness team dressed up as the competing mammals and acted out the battle in front of a green screen. The battle was then edited together and the final video was tweeted out during the first day of the 2017 March Mammal Madness season.

In 2018, brief summaries of the battles in the style of sports reporting were added, providing for a short recap of each encounter.

All tables begin with round two, after the first elimination. If no animals advanced the cell is grey, if the animal was the champion the cell is gold.
