| 實物特徵: | Abundance, distribution and species association of Trichocereus pasacana were studied at Los Cardones National Park Salta, Argentina. 3200 ha were sampled using areal methods. Mean density was 34,33 individuals ha. Two distinctive groups were found: one of higher density including number of renewals, and the other of lower density and absence of renewals. Altitude was negatively related to density. Adults distribute randomly, while renewals are found agregated. 20% of individual s were associated to Larrea divaricata and 37% with L. divaricata, Bougainvillea sp., Baccharis spp. and Prosopis ferox. Only II % was not associated |
