The cycad %amia loddigesii Miq. forms a morphologically variable complex on the Yucatan peninsula, Mexico. Several diploid chromosome numbers have been found in the species: In= 17, 24, 25, 26 and 27. Differing karyotypes and chromosome numbers were found in individuals of the same population and die karyotypes differ widely in numbers of metacentric and telocentric chromosomes present. Centrometric fission as well as pericentric inversions and unequal translocations are suggested to be the probable mechanisms for this karyotype variation. There appears to be a correlation between high chromosome number and increasing dryness of the habitats. Coupled with the strongly asymmetrical karyotypes, this suggests that karyotype evolution in Z‐ loddigesii is recent.
El presente ensayo nos propone reflexionar sobre las corporalidades no binarias en relación con los conceptos tiempo/espacio, a partir de la censura de un mural[1] ocurrido durante el mes de noviembre de 2018, en el departamento de Chimbas de la provincia de San Juan. El hecho, que funciona como un disparador, nos permite, a través de nociones de la temporalidad y la geografía queer, dislocar la línea temporal y espacial de lo acontecido y vincularlo con otros hechos de marginalización. El texto nos conduce a un modo posible de comprender el acontecimiento de censura, como parte del dispositivo de control del sistema dicotómico sexo-género que moldea tanto cuerpos, performances, como espacios-tiempos.[1] Mural realizado dentro del Maaanso Encuentro Internacional de Muralistas y Graffiteros en el departamento de Chimbas, San Juan, durante el mes de noviembre de 2018.
