Hawaiian Names on the Volcanoes
Four Decades of Landscape Change on a Granite Dome (Enchanted Rock, Texas)
This study focuses on photographic analysis of Enchanted Rock, a granite dome in central Texas; fourteen photo pairs compare contrasting views after—thirty-six to forty-six years, and assess changes in geomorphology, sediments, and vegetation on miniature landforms, especially erosional depressions—gnammas and vernal pools. Several distinct landscape changes occurred during the study period, but these affected sites unevenly. Vegetation displayed…
Phytogeomorphic Influence of Stone Covers and Boulders on Plant Distribution and Slope Processes in High‐Mountain Areas
This study reviews several effects stones have on slope geomorphic processes and plant distribution at high elevations, with emphasis on low‐latitude mountains and volcanic environments and rosette plants. It begins by considering how vegetation becomes established on relatively stable footslopes and the principal influences that outcrops and isolated boulders have on slope movement and vegetation development, moves to a comparison of the princip…

Geophagy of Holstein Hybrid Cattle in the Northern Andes, Venezuela
During the course of a Quaternary stratigraphic reconnaissance of the northern Venezuelan Andes, W. C. Mahaney and M. Bezada observed Holstein hybrid cattle consuming reddish-brown soil formed in residual regolith from bedrock outcrops (Figure 1). In all cases, the source sites of the eaten soils were located above 3,000 m a.s.l. in the Venezuelan paramo. While there are a number of such sites, only one was sampled to characterize mineral composi…
A High-Andean Toposequence
Turf Destruction by Cattle in the High Equatorial Andes
The Paramo de Piedras Blancas is a high-altitude area of the Venezuelan Andes, located 40 km northeast of the city of Merida at 80 51' N, 700 53' W. Its climate is characterized by frequent nightly freezing (down to --11? C at 4,265 m); this allows recurrent growth of needle ice, a type of ground frost extremely destructive of vegetation (Perez, 1987). Yearly precipitation is <: 800 mm, distributed into two distinct seasons. Paramo vegetation is …
The Ecological Impact of Cattle on Caulescent Andean Rosettes in a High Venezuelan Paramo
The impact of cattle on caulescent Andean rosettes was studied in the Paramo de Piedras Blancas, Venezuela. Cattle were introduced into the Andes by the Spaniards in the late 1500s, but probably did not affect this paramo until the 19th century. Cows feed on the leaves of one species, Coespeletia timotensis, as a diet supplement mainly during the dry season, but avoid other rosettes. Browsing is concentrated on the intermediate size-classes of ro…
