Descrizione dell’articolo da parte del venditore

Multiple discriminant analysis and principal component analysis were found useful in interpreting distributions of two land snails in a desert canyon in Arizona. Snail presence and abundance in small, arbitrarily chosen sites can be accurately predicted from 5 environmental variables: elevation, slope angle, slope aspect, percent vegetational cover and substrate type. Though correlation among the environmental variables was high, vegetational cover was found to account for most of the variance in snail presence. Independent of vegetation, slope aspect, slope angle, and elevation were not demonstrated to affect the presence of snails. The 2 snail species commonly found living in the canyon, Discus cronkhitei and Sonorella baboquivariensis cossi, differ significantly in their preference of slope angle and substrate. Apparently Sonorella was found more commonly on steep rocky slopes because it requires rocks for shelter. Discus, a much smaller snail, can find adequate shelter in loosely packed humus and thus inhabits shallower slopes where humus accumulates. 7 pp., 2 figs, gr. 8.

Founded in 1985 we are specialized in worldwide literature on Mollusca and marine invertebrates. Our publishing house has meanwhile published approximately 60 titles on that field of interest. We have stocks of most available international books on Malacology and a huge amount of antiquarian literature, even of the latter most titles are only available once.
