Opuntia phaeacantha centers, and sometimes peach, pinkish or reddish overall. The edible fruits are red or purple with green flesh. The pads and fruit bear tiny glochids which can lodge in the skin and cause irritation. This plant, like other "Opuntia" species, is attacked by cactus moth. Older names for this species, and names for old species which are now considered variants of this species, include plateau prickly pear, brown-spined prickly-pear, Mojave prickly pear, and Kingman prickly pear. The species is widespread, from California to Texas to Colorado and New Mexico, and into Mexico. There are multiple variations and perhaps these will
Plant functional type key parameters are defined, such as fecundity, competitiveness, resorption (rate at which plant decays and returns nutrients to the soil after death), etc.; the value of each parameter is determined or inferred from observable characteristics such as plant height, leaf area, etc. Climatologists and ecologists struggle to determine which minimal set of plant characteristics best model the actual responses of the biosphere in response to climate changes. Plant functional type Plant functional types (PFTs) is a system used by climatologists to classify plants according to their physical, phylogenetic and phenological characteristics as part of an overall effort to develop a
