Evolving towards semelparity in Andean Puya (Bromeliaceae): testing differential investment in reproductive displays. Co-authors Cody Williams and Kenneth J. Sytsma. Semelparity (syn. monocarpy), the life-history trait of senescing after a single, massive sexual reproduction episode, is relatively rare in long-lived angiosperms. Puya (Bromeliaceae), a large genus of long-lived, terrestrial Andean rosette plants, were found during fieldwork through the Andes to exhibit variability in life history type. The majority of species are iteroparous, producing vegetative daughter rosettes before producing terminal inflorescences. Several species, primarily from high elevations in the wetter northern Andes, often reproduce and die with no vegetative reproduction, and are a placed in a new category here called semi-semelparous. Only Puya raimondii, the largest bromeliad on earth from the high-elevation, drier central Andes, is always semelparous. Semelparous taxa in other giant rosette genera (Yucca, Agave, Lobelia ) have been shown to invest more energy in reproductive displays than close iteroparous relatives. To see if the semi-semelparous taxa are evolving towards true semelparity, photographs of the majority of Puya species in the field were converted into pixels and the ratio between the inflorescence and vegetative rosette area was calculated and compared between iteroparous, semi-semelparous and semelparous taxa. Permutations of these data (eg, exponentially scaled) were …

Composts various uses improve soil quality and productivity as well as prevent and control erosion. Mixed organic materials, such as animal manure, yard trimmings, food waste, and biosolids, must go through a controlled heat process before they can be used as high quality, biologically stable, and mature compost. Fertilizer, as defined by the US Department of Agriculture, is a single or blended substance containing one or more recognized plant nutrient(s) used primarily for its plant nutrient content claimed to have value in promoting plant growth. While compost contains many of the same characteristics as fertilizer, such as nutrients, it is not considered a complete fertilizer unless amended. The recovered organic materials from which compost and fertilizer are made include, but are not limited to, yard waste, food waste, manure and biosolids. Additional organic materials are listed on pages 4-8 of the document below, CPG V Appendices (Biosolids, Manure, and Fertilizers) (PDF) (30 pp, 112K, About PDF). EPA recognizes that these organic materials are the most commonly used in commercially available compost but other organic materials could also be used. Yard waste utilizes …
