“…The divergent phenological patterns seen among plants with similar growth habits, as in the study by Petit (2001), however, may be explained by selective biotic pressures. Among the many possible selective factors, pollination agents have received the greatest attention.…”

“…Seasonal rainfall has often been cited as the determinant climatic factor in these areas (Reich 1994, Williams-Linera & Meave 2002, and has thus been associated with the seasonality of phenological phenomena -principally in plants having shallow root systems (and unable to use deep soil water) and non-succulents (Nobel 1977, Sarmiento & Monastério 1983, Bertiller et al 1991. Petit (2001) examined the responses of three sympatric columnar cacti to rainfall on the semi-arid island of Curaçao, and determined that each species responded differently to limitations presented by seasonal water shortages. These results are similar to those reported by Pavón & Briones (2001) for perennial shrubs in Mexico.…”

“…Buxb., Subpilocereus repandus (L.) Backeb. y Pilosocereus lanuginosus (L.) Byles & G.D. Rowley la fecundidad está asociada al número de tallos (Steenbergh & Lowe 1977, Petit 2001. Esto es debido a que las plantas más grandes tienen mayor área fotosintética y tejido suculento para almacenar agua que las plantas pequeñas, por lo tanto son capaces de acumular y asignar más recursos a la función reproductiva (Nobel 2002).…”

“…En el piso de cactáceas predominan: Neoraimondia arequipensis, Cereus amazonicus, Calymmanthium sp., Melocactus sp., Jatropha macrantha, Orthopterygium huancui y Viguiera sp. Estas plantas aumentan su densidad hacia los 1000 msnm (ONERN, 1976;Weberbauer, 1945 Rondón (1994) modificada para esta especie, considerando a los botones abortados como un estadio fenológico por presentarse en gran cantidad (Petit, 2001;McIntosh, 2002 (Greennacre, 1984;McCune & Grace, 2002). A partir de una tabla de contingencia que en este caso fue la tabla que muestra el número de individuos que presentaron una o más de las distintas nueve fenofases durante los meses de evaluación, se creó una matriz de disimilitud transformada empleando la distancia Chi-cuadrado, la cual dará una mayor ponderación a los estados fenológicos cuyas abundancias hayan sido muy bajas dentro de la matriz original.…”
