Anthropogenic transformation of forest ecosystems by geochemical and photosynthetic parameters

چکیده
Geochemical and physiological indices gained at the background area under anthropogenic impact were compared. The study sites comprise 30 sample areas each. Overall, 600 samples of pine needles designated for delayed chlorophyll fluorescence measurement as well 60 soil needle correspondingly selected to perform geochemical analysis. biological uptake urban ecosystems is represented in range: Mn (10,16) > P (7,19) Ag (2,78) Ba (2,76) Cu (2,31) Sr (1,85) Ni (1,80) Zn (1,75) Pb (0,86) Co (0,48) Cr (0,40) Zr (0,37) V (0,36) Ga (0,33) Ti (0,21). In comparison with site data increased regard V, Ti, Ni, Cu, Cr. methodology implies method recording relative index help fluorimeter “Photon 10”. accumulated course analysis allowed distinguish common features revealed differences qualities. value (RIDF) considerable lower by 25% more related site. This deviation testifies that human present even on early stage ecosystem degradation.

compactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

Coral reef ecosystems and anthropogenic climate change
Coral reef ecosystems are among the most biologically diverse ecosystems on the planet. In addition to their value in terms of biodiversity, coral reefs provide food and resources for over 500 million people. Despite their importance, coral reefs are declining at a rapid rate (1–2% per year) as a result of a range of local (e.g., overexploitation of fisheries, declining water quality) and globa...
متن کاملOrganic Geochemical Biosignatures in Alkaline Hydrothermal Ecosystems
The 13C content of microbial products are controlled by many factors, including the 13C content of the growth substrate, growth rate, the flux of carbon through various parts of the biochemical network, and the isotopic fractionation imposed by the enzymes of that network. We analyzed the 13C content of products of the methanogen Methanosarcina barkeri and found that fractionation varied strong...
