Woody debris, which is supplied by branch litter, is an important component of forest ecosystems as it contains large quantities of organic matter and nutrients. We evaluated changes in branch wood dry weight and nutrient content of six common species (Fraxinus rhynchophylla, Pinus densiflora, Prunus sargentii, Quercus mongolica, Acer pseudosieboldianum, and Symplocos chinensis for. pilosa) in ...

The resorption protection hypothesis, which states that anthocyanins protect foliar nutrient resorption during senescence by shielding photosynthetic tissues from excess light, was tested using wild-type (WT) and anthocyanin-deficient mutants of three deciduous woody species, Cornus sericea, Vaccinium elliottii (Chapmn.), and Viburnum sargentii (Koehne). WT Betula papyrifera (Marsh) was include...

We surveyed variation in allozymes and in the mtDNA cytochrome oxidase subunit II (COII) gene in populations of three nominal species of hairstreak butterßies in the genus Mitoura in northern California. These species are separated on the basis of wing pattern and larval hostplant differences: M. nelsoni (Boisduval) larvae feed on incense cedar, Calocedrus decurrens (Torrey); M. muiri(Hy.Edward...

Climate change will alter natural areas on a global scale within the next century, especially in low-lying coastal where sea-level rise is predicted to severely degrade or destroy many ecosystems. As continues, it expected that salinity due saltwater intrusion impact soil health and agricultural production, this of even greater importance such as South Florida surface groundwater resources are ...

Dams are gray infrastructure, providing various benefits such as flood control, water supply, and power generation. In order to create the next generation of infrastructure that explores how nature can act meet development ecological sustainability, artificial plantings have been attempted on dam slopes in Korea since 2000. As planted trees now stabilized form a forest, it is time study floral ...
