Resumen: "Over a 31- day period, the decom positio n pro cess, beetl e di versity and success ion on clothed pig (Sus
scrofa L.) carcass es were studied in ope n (agricu ltural lan d) and sha ded habitat (second ary fores t) in
South ern Mexico. The decom positi on process wa s catego rised into ?ve stages: fre sh, bloate d, active
decay , adv anced decay and rem ains. Except for th e bloate d sta ge, th e elapsed time for each
decomp ositio n stage was s imilar betwe en ope n and sha ded hab itats, all carcasses reached an advan ced
decay stage in seven days, and th e ?fth sta ge (rema ins) was not record ed in any carcass during the time
of this s tudy. A tot al of 6344 bee tles, belong ing to 130 specie s and 21 famil ies, we re collected during the
entire deco mpositi on process, and abunda nces increa sed from fresh to adv anced decay stages.
Staphylin idae , Scarab aeid ae and Histerid ae were taxonomi cally and num ericall y domi nant, accoun ting
