or if they are, not considered as flowers. For example, the bearded tufts at the tips of grasses, the heads of cattails, the unripe ears of corn and the small tassels that somewhat resemble certain caterpillars and hang from birches and alders early in spring, are all clusters” of real...
32. It has long been known that soil can affect plant evolution through imposing selection on mechanisms for nutrient gain, potentially leading to edaphic specialization and the formation of plant races1,8,78. We show
Plants including grasses, shrubs, and trees absorb and volatilize heavy metals from polluted soil, some can accumulate As, Pb, Hg, Cr, Zn, Cu and get trapped in roots [14]. Accumulation of heavy metals in plant harvestable tissues involves the metals-tolerant to extract contaminates from ...
When considering invasive species, grasses might not be at the top of mind. However, one type of grass is particularly dangerous to Florida's natural ecosystem: cogon grass. Indigenous to southeast Asia, this species came to the U.S. in 1911. Classified as both a weed and a pest, cogo...
For these reasons, dachshunds and terriers belong among the most common breeds for hunting all kinds of game in the Czech Republic. These breeds are considered to be independently working breeds that are able to work without visual contact with the hunter. We used two different dog-breed ...
35. The significance of biochar in promoting water retention and shallow slope stability was also demonstrated by Ng et al.36. They reported that the soil micropore increased by 22% in response to adding 0 to 10% biochar. Ng et al.37also stated that the grassed cover with 0 to 10% ...
Because we are students, we must obey many different kinds of rules in our classroom. We should first understand(明白,理解)these rules and then we can really obey them. For example(例如), students can’t bring food into the classroom, because our classroom is a place for studying, not ea...
Thyme (Thymusgenus) and oregano (Origanumgenus) are two important kinds of medicinal and aromatic plants in the Lamiaceae family. At the time this paper was written, the World Flora Online (WFO,http://www.worldfloraonline.org) website has collected 366 thyme species or subspecies, 118 thyme...
Tolerance of grasses to heavy metals and microbial functional diversity in soils contaminated with copper nine tailings. Pedosphere 18, 363–370 (2008). 38. Martens, D. A., Johanson J. B. & Frankenberger, J. W. T. Production and persistence of soil enzymes with repeated addition of ...
Savannah ecosystems extend across tropical and subtropical regions of the world. Continuous herbaceous layers, usually dominated by grasses or sedges, and a discontinuous layer of trees and/or shrubs, as well as a deep seasonality, characterize these ecosystems and their functioning1,2. Humans have...
