【 摘 要 】
Dwarf mistletoes ( Arceuthobiumspp.) are important plants in temperate forests of Mexico due to their high incidence. At the south side of the Papayo Hill in the “Zoquiapan y Anexas” Natural Protected Area, Mexico State, both,Arceuthobium vaginatumsubsp.vaginatumandA. globosumsubsp.grandicaulecoexist within the same zone and, frequently, on the same host tree of the speciesPinus hartwegii . We studied the vertical distribution of both species on the stem, and we registered thatA. vaginatumis found more frequently to lower heights of the pines thanA. globosum . These results suggest that the nutritional resources are taken in a differential manner, causing a probable competitive relation between the two species.
