Start small. End big. March, capped by a hyperactive 10-day stretch, registered a real impact on SI.com's latest mixed martial arts rankings.

Here's a by-the-numbers look across eight weight divisions, plus pound-for-pound:

1 ... Bantamweight has a new man at the top. Again. Stability doesn't appear to be a hallmark of the 135-pound class, but Dominick Cruz intends to do something about that. With his victory on March 6 over Brian Bowles, Cruz vaulted to the division's top spot -- the only change at No. 1 heading into April.

5 ... Promotional organizations represented in the pound-for-pound list: UFC (4); WEC (2); Strikeforce (2); Dream (1); M-1 Global (1).

6 ... Bookended by familiar faces, the chunk of the heavyweight division brought about shifts in positions 3 through 8. From Frank Mir, Cain Velasquez, Antonio Rodrigo Nogueira, Alistair Overeem, Shane Carwin and Junior dos Santos at the beginning of March to Carwin, Velasquez, Dos Santos, Mir, Nogueira and Overeem at its close. The top -- Fedor Emelianenko and Brock Lesnar -- and bottom -- Brett Rogers and Alistair Overeem -- pairs stay the same.

7 ... Currently-ranked fighters who competed under the UFC banner from March 21-31. ... Number of spots Japan's Masakatsu Ueda dropped after taking the first loss of his career, which caused him to relinquish the Shooto 132-pound belt to Shuichiro Katsumura.

9 ... Nationalities according to frequency: U.S. (36); Brazil (19); Japan (17); Armenia (2); England (2); Russia (1); Canada (1); Netherlands (1); Belarus (1)

10 ... Jorge Santiago recaptured his position at the bottom of the middleweight division following a five-round decision against Mamed Khalidov. Santiago, who retained his Sengoku title against the Polish Khalidov, is joined by Jon Jones, featherweight Marlon Sandro, and bantamweight Masakatsu Ueda as fighters appearing at No. 10 for the first time. Ueda surrendered his perfect record and fell seven spots.

22 ... Age of Jones, the youngest fighter on the list, debuts in the light heavyweight division.

68.5 ... Percent of ranked fighters from heavyweight to bantamweight under contract to Zuffa.

125 pounds ... The only division to remain untouched throughout March.
