BIO 227 Chapter Notes - Chapter final: Carbon Footprint, Quino Checkerspot, Plantago Erecta
Document Summary
Quino checkerspot butterfly populations mostly occur in metapopulations, as the success rate is higher than isolated habitat patches. Local habitat patch populations are linked through extirpation and mutual recolonization, which occur every 10 to 40 years. These habitat patch distributions are found primarily on nectar and oviposition plants, as well as basking sites. Oviposition plants of quino checkerspot include dwarf plantain (plantago erecta), which have soils with cryptogamic crusts or finely-textured clay, woolly plantain (plantago patagonica), and white snapdragon (anterrhinum coulterianum). The most important characterisitics of the host plants are exposure to solar radiation and timing of development (phenology). The ideal host plant is surrounded by bare ground or sparse low-growing vegetation, is in full sunlight, and remains edible for about 8 weeks. The first petition to list the quino checkerspot butterfly as endangered was published on august. The final rule listing the quino checkerspot as endangered was published january 16, 1997.
