 Ramba uchiverenga ndima iyi - Iri ndiro rondedzero yemhuka dzomusango dzinoyamwisa dzomunharaunda dzakanyorwa muMexico. Pakazosvika September 2014, paiva nemhando dzemhuka dzinoyamwisa kana kuti dzesubspecies 536 dzakanyorwa. Zvichienderana nemashoko eIUCN, Mexico ine 23 yemarudzi emhuka dzinoyamwisa dzisiri dzemhuka kupfuura US neCanada dzakabatanidzwa munzvimbo yakakura 10 chete, kana kuwanda kwemarudzi kanopfuura ka12 kupfuura evavakidzani vayo vekuchamhembe. Kusiyana-siyana kwezvinhu zvipenyu zvinokambaira muMexico kunoratidzawo zvakasiyana-siyana zvinorarama munyika yacho, kubva kumasango anogara achinaya ari munzvimbo dzakaderera kusvika kunzvimbo dzisina kunyanya kunaya, uye kubva kumasango emumakomo kusvika kunzvimbo dzakakwirira. Kuwedzera kworudzi rwoupenyu hwomunyika huri kufamba kuenda kuEquator ndechimwe chinhu chinokosha pakuenzanisa. Mexico inosanganisira mazhinji emasango eMesoamerican neMadrean pine-oak nzvimbo dzinopisa dzemarudzi akasiyana-siyana. Kubva pakuona kwoupenyu nenzvimbo, chikamu chikuru cheMexico chakabatanidzwa nedzimwe nyika dzokuNorth America sechikamu chenyika yeNearctic. Zvisinei, nzvimbo dzakaderera dzokumaodzanyemba kweMexico dzakabatanidzwa neCentral America neSouth America sorutivi rwenyika yeNeotropical. Kusanganiswa kukuru kwemarudzi emhuka dzinoyamwisa dzomuNearctic neNeotropical kwakatanga makore mamiriyoni matatu bedzi apfuura, apo kuumbwa kweIsthmus yePanama kwakagumisa nhambo refu yokuzviparadzanisa kweSouth America ndokukurumidzisa Great American Interchange. Makumi maviri emarudzi asingabhururuki aripo muMexico opossums, armadillos, anteaters, tsoko uye zvipembenene zvinonzi caviomorph anobva kuSouth America. Zvizhinji zvezvisikwa zvikuru zvaimbogara munharaunda yacho zvakatsakatika pakupera kwePleistocene makore 10 000 akapfuura, nguva pfupi vanhu vokutanga vasvika. Kuwedzera kwekushandurwa nekuparadzwa kwenzvimbo dzinogarwa nevanhu nekuwedzera kwenhamba yevanhu mukati memazana emakore mashoma apfuura kuri kukonzera kumwe kuparara kwehupenyu mudunhu iri, sezvakaratidzwa ne hotspot mazita nekutsanangurwa, nzvimbo dzakadai dzakarasikirwa neanopfuura 70 emiti yavo yekutanga.
